Such spacecraft operate under various gravity conditions, but previous studies have mostly considered the influence of gravity conditions on the constrained melting process of a PCM and not on its unconstrained melting process. In this study, a numerical model was constructed to comprehensively analyze the constrained and unconstrained melting processes of a PCM inside a spherical capsule under low-gravity conditions. After validation, the model was then applied to investigating the effects of low-gravity conditions on the evolution of velocity, temperature, melt layer thickness, heat transfer, liquid fraction, and total melting time. For the unconstrained melting process, low-gravity conditions weaken buoyancy-driven natural convection and slow down the solid PCM downward trend, thereby limiting the melting rate. In addition, the melt layer thickness does not increase linearly with decreasing gravity. Specifically, the increase in melt layer thickness is smaller by about 1.06 mm when the gravity drops from 0.4g to 0.2g compared to when it drops from 0.2g to 0.1g. The local heat flux in the contact melting area gradually decreases with the reduction of gravity during the unconstrained melting process. During the constrained melting process, notable oscillations in the local heat flux were observed. Decreasing the gravity from g to 0g increased the total melting times of the constrained and unconstrained melting processes by 417% and 621%, respectively.展开更多

文摘BACKGROUND The accuracy of blind intra-articular injections in the shoulder is rather low.Inaccurate injections tend to lead to poorer treatment outcomes.The“Delaware posterior bone touch technique”has shown higher accuracy in young,slender,healthy volunteers than the classical“Cyriax technique”.AIM To investigate whether the Delaware technique would also be more accurate in older patients with capsulitis.METHODS We analyzed the files of 100 consecutive patients with capsulitis who were treated with an intra-articular injection containing a mixture of triamcinolone,lidocaine,and air.After the injection,the shoulder was moved to determine whether a squishing sound could be produced.The squishing sound was interpreted as an accurate injection.The scores with the new Delaware technique were compared against those with the Cyriax technique in a previous study.RESULTS Squishing was heard after 87%of the injections.This was 13%(10%points)more than the 77%in the previous study(P=0.004).CONCLUSION The Delaware technique was significantly more accurate than the Cyriax technique also in middle aged patients with capsulitis.We hypothesize that the difference is caused by a lower risk that a part of the opening of the needle is still outside the capsule.

文摘Objective:To observe the clinical efficacy of different acupuncture modalities in the treatment of adhesive capsulitis a tthrough different clinical stages.Methods:Ninety patients of adhesive capsulitis weregraded in three different stages based on clinical presentations.Patients in painful stage were treated with silver needles once every 5 to 7 days for two courses;patients in adhesive stage were given acupotomy treatment every 7 to 10 days for two courses;while patients in recovery stage were treated with acupuncture with warm needles by moxibustion on tendon knots,once a day 10 times in a course,for two courses of treatment.The disease scores were compared between all groups before and after the treatment,and clinical efficacy was evaluated after the treatment.Results:The disease scores in patients of all three stages were higher after treatment,and the differences were statistically significant(all P<0.05).Among 90 patients with adhesive capsulitis,32 cases were clinically under controlled,37 cases claimed remarkably effective,18 were effective,and 3 ineffective cases,thus the total effective rate for this stage-based treatment is 96.7%.Conclusion:For adhesive capsulitis,different acupuncture modalities targeting patients in different clinical stages were feasible and effective,the disease scores of patients were significantly improved.
文摘BACKGROUND Adhesive capsulitis is a relatively common condition that can develop in cancer patients during treatment.Positron emission tomography-computed tomography(PET-CT)is routinely performed as a follow-up study in cancer patients after therapy.Being aware of PET-CT findings to suggest shoulder adhesive capsulitis may help to alert clinicians for the diagnosis of unsuspected shoulder capsulitis.AIM To assess the association of shoulder adhesive capsulitis with cancer/therapy type and symptoms in cancer patients undergoing PET-CT.METHODS Our prospective study received Institutional Review Board approval.Written informed consent was obtained from all patients,who answered a questionnaire regarding shoulder pain/stiffness at the time of PET-CT study,between March 2015 and April 2019.Patients with advanced glenohumeral arthrosis,metastatic disease or other mass in the shoulder,or shoulder arthroplasty were excluded.Patterns of shoulder capsule 18F-fluorodeoxyglucose(FDG)uptake were noted.Standard Uptake Value(SUV)max and SUVmean values were measured at rotator interval(RI)and deltoid muscle in bilateral shoulders.Normalized SUV(SUV of RI/SUV of deltoid muscle)was also calculated.We assessed if SUV values are different between symptomatic and asymptomatic patients in both shoulders.Covariates were age,gender,and therapy type(surgery,chemotherapy,radiation).Wilcoxon rank sum tests were used to compare unadjusted marginal differences for age,SUV measurements between symptomatic and asymptomatic patients.Multiple linear regression models were used to examine the relationship between right or left shoulder SUV measurements and symptom status,after adjusting for covariates.Statistical significance level was set at P<0.05.RESULTS Of 252 patients initially enrolled for the study(mean age 66 years,67 symptomatic),shoulder PET-CT data were obtained in 200 patients(52 were excluded due to exclusion criteria above).The most common cancer types were lymphoma(n=61),lung(n=54)and breast(n=53).No significant difference was noted between symptomatic and asymptomatic patients in terms of age,gender,proportion of patients who had surgical therapy and radiation therapy.A proportion of patients who received chemotherapy was higher in patients who were asymptomatic in the right shoulder compared to those symptomatic in the right shoulder(65%vs 48%,P=0.012).No such difference was seen for the left shoulder.In both shoulders,SUVmax and SUVmean were higher in symptomatic shoulders than asymptomatic shoulders(Left SUVmax 2.0 vs 1.6,SUVmean 1.6 vs 1.3,both P<0.002;Right SUVmax 2.2 vs 1.8,SUVmean 1.8 vs 1.5,both P<0.01).For lung cancer patients,bilateral RI SUVmax and SUVmean values were higher in symptomatic shoulders than asymptomatic shoulders.For other cancer patients,symptomatic patients had higher left RI SUVmax/mean than asymptomatic patients after adjustment.CONCLUSION In symptomatic patients metabolic activities in RI were higher than asymptomatic patients.Adhesive capsulitis should be considered in cancer patients with shoulder symptoms and positive FDG uptake in RI.
文摘The objective of this study was to compare the effectiveness of Kaltenborn joint mobilization techniques with muscle energy techniques in adhesive capsulitis.Study was conducted in population of Sargodha who is seeking physiotherapy treatment for adhesive capsulitis in physiotherapy rehabilitation departments and centers.The study design was randomized,controlled,and multicenter.Around 75 patients were selected by inclusion and exclusion criteria,and were divided into three groups by lottery method of randomization.Group 1 obtained Kaltenborn method of treatment,Group 2 obtained muscle energy technique,and Group 3 is control group that obtained conventional treatment in the form of heat and range of motion exercises.Duration of study was 6 months,and the interventions were performed for two weeks,with a total of 10 sessions.A baseline measurement was taken on shoulder pain and disability index(SPADI).A post intervention measurement was taken on same outcome measurement tools and was compared using ANOVA statistical analysis.The pre-intervention measurements on SPADI were 61.11±8.79,60.91±9.90,and 61.18±9.00 in control,Kaltenborn,and METs groups,respectively.The post intervention measurements were 49.33±9.95,39.09±9.45,and 27.69±11.97 in control,Kaltenborn,and METs groups,respectively.This study concluded that both techniques are effective in the treatment of adhesive capsulitis to decrease the pain and disability in experimental groups in comparison to control groups.METs is superior to Kaltenborn in pain and disability management when compared to each other.

文摘Encapsulation of water-soluble cargoes in millimeter-sized capsules has enabled major advances in various fields,including pharmaceuticals,food,cosmetics,packaging,and materials.However,because of the lack of fabrication precision,low cargo retention,suboptimal mechanical properties,and difficulty in preventing water evaporation,this technique is more challenging than microencapsulation techniques.In this study,we developed a surfactant-free and organic solvent-free water-in-oil in-air emulsification approach for synthesizing double-layered“milli-capsules”for the precise encapsulation,enhanced retention,and force-triggered burst release of water-soluble bioactive cargoes.In particular,we synthesized milli-capsules with a first shell of poly(ethylene glycol dimethacrylate)for the efficient encapsulation of bioactive cargoes and a second shell of beeswax to prolong the retention of the entrapped bioactive compounds.Unlike traditional milli-capsules,which exhibit poor shape uniformity and mechanical stability,we introduced metallic ions to stabilize the interfacial tension and employed constant rotation to balance the gravity,buoyancy,inertial,and viscous forces imposed on the droplets,resulting in uniform and rigid milli-capsules with narrow rupture forces.Furthermore,additional hydrophobic beeswax coating prevented water volatilization and substantially prolonged the shelf life of the encapsulated compounds from a few days to a few months while maintaining their bioactivities.The proposed milli-capsule system addresses the challenge of precise fabrication of large carriers for water-soluble cargoes,representing a significant step toward the long-term storage and controlled release of bioactive cargoes for various industrial applications.
文摘AIM:To assess the visual acuity and visual quality of cataract patients who received femtosecond laser-assisted cataract surgery(FLACS)and multifocal intraocular lens(MIOL)implantation with an improved polishing technique during a 1-year follow-up period.METHODS:This study included 74 eyes from 37 patients,comprising 17 males and 20 females,with a mean age of 51.74±7.80 years.Using a coin toss method,one eye per patient was randomly selected for improved anterior capsular polishing,while the other eye received standard irrigation/aspiration(I/A)polishing.The polishing group consisted of 37 eyes,including 21 right and 16 left eyes,while the control group comprised the contralateral fellow eyes of the same individuals in the polishing group.Visual acuity and quality of the patients were evaluated before surgery and at 1 wk,1,6,and 12 mo after surgery.The OPD-Scan III was utilized to assess high-order aberrations,while the optical quality analysis system(OQAS)was employed to evaluate modulation transfer function(MTF cutoff),Strehl ratio(SR),and objective scatter index(OSI)for the purpose of visual quality assessment.Paired t-tests and repeated measures analysis of variance(ANOVA)were utilized to compare the results,and the SNK-q post hoc test was applied to identify significant differences.RESULTS:The polishing group’s uncorrected distant visual acuity(UDVA)and uncorrected near visual acuity(UNVA)significantly improved 1-week post-surgery(all P<0.05).At 12-months,UDVA,UNVA,and corrected distant visual acuity(CDVA)were better than the control group(P<0.05).The MTF cutoff,SR,OSI,and high-order aberrations in the polishing group also showed significant improvements compared to the control group at 12 mo(P<0.05).CONCLUSION:The improved capsular polishing method has been demonstrated to effectively maintain visual acuity and visual quality in patients with MIOL after FLACS within 1 a.

文摘The melting process of a phase change material(PCM) inside a capsule can be promising in the thermal management of spacecraft. Such spacecraft operate under various gravity conditions, but previous studies have mostly considered the influence of gravity conditions on the constrained melting process of a PCM and not on its unconstrained melting process. In this study, a numerical model was constructed to comprehensively analyze the constrained and unconstrained melting processes of a PCM inside a spherical capsule under low-gravity conditions. After validation, the model was then applied to investigating the effects of low-gravity conditions on the evolution of velocity, temperature, melt layer thickness, heat transfer, liquid fraction, and total melting time. For the unconstrained melting process, low-gravity conditions weaken buoyancy-driven natural convection and slow down the solid PCM downward trend, thereby limiting the melting rate. In addition, the melt layer thickness does not increase linearly with decreasing gravity. Specifically, the increase in melt layer thickness is smaller by about 1.06 mm when the gravity drops from 0.4g to 0.2g compared to when it drops from 0.2g to 0.1g. The local heat flux in the contact melting area gradually decreases with the reduction of gravity during the unconstrained melting process. During the constrained melting process, notable oscillations in the local heat flux were observed. Decreasing the gravity from g to 0g increased the total melting times of the constrained and unconstrained melting processes by 417% and 621%, respectively.

文摘Wireless capsule endoscopy(WCE)has the potential to fully replace conventional wired counterparts for its low invasiveness.Recent studies have attempted to expand the functions of capsules toward this goal.However,limitations in space and energy supply have resulted in the inability to perform multiple diagnostic and treatment tasks using a single capsule.In this study,we developed a dual-functional capsule robot(DFCR)for drug delivery and tissue biopsy based on magnetic torsion spring technology.The delivery module was shown to rotate the push rod with a thrust of 894 mN to release approximately 0.3 mL of semisolid drug.The biopsy module used a built-in blade to cut tissue with a shear stress of 22.87 MPa,producing a sample of approximately 1.8 mm3.Additionally,a five-degree-of-freedom permanent magnet drive system was developed.By adjusting the strength of the unidirectional magnetic field generated by an external magnet,the capsule can be wirelessly controlled to sequentially trigger the two functions.Ex vivo tests on porcine stomachs confirmed the feasibility of the prototype capsule(12 mm in diameter and 45 mm in length)in active movement,medication,and tissue biopsy.The newly developed DFCR further expands the clinical application prospects of WCE robots in minimally invasive surgery.
文摘BACKGROUND Mucosal healing has become an important goal of Crohn’s disease(CD)treat-ments.Modulen,enriched with transforming growth factor-beta 2,and budeso-nide are commonly accepted treatments for mild-moderate CD.However,their effects on the small bowel(SB)mucosa remain underexplored.AIM To prospectively assess clinical and mucosal responses to Modulen vs budesonide in adults with CD,using SB capsule endoscopy.METHODS Thirty patients were divided into two groups:Modulen+home-based diet(21 patients)and budesonide(9 patients)for an eight-week intervention followed by four weeks of follow-up.Clinical,laboratory,and endoscopic responses were evaluated.The mucosal changes were assessed through SB capsule endoscopy.RESULTS Results indicated significant clinical improvement in the Modulen group with reduced CD activity index(P=0.041)and improved inflammatory bowel disease questionnaire score(P=0.016).Moreover,Modulen was associated with a signifi-cant SB mucosal improvement,evidenced by a decrease in Lewis score(P=0.027).No significant changes were observed in calprotectin or other laboratory parame-ters.Conversely,budesonide exhibited more modest clinical effects,but it improved calprotectin,hemoglobin,and C-reactive protein levels(P=0.051,P=0.014,and P=0.038,respectively).The capsule endoscopy did not reveal a significant mucosal response in the budesonide group.CONCLUSION Both interventions have a role in CD treatment.Yet,their effects differ and may complement each other:Modulen yields clinical and mucosal improvements,while budesonide primarily leads mainly to laboratory improvements.

文摘OBJECTIVE:To explore the potential molecular mechanism of Qigu capsule(芪骨胶囊,QGC) in the treatment of sarcopenia through network pharmacology and to verify it experimentally.METHODS:The active compounds of QGC and common targets between QGC and sarcopenia were screened from databases.Then the herbs-compounds-targets network,and protein-protein interaction(PPI) network was constructed.Gene ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were performed by R software.Next,we used a dexamethasone-induced sarcopenia mouse model to evaluate the anti-sarcopenic mechanism of QGC.RESULTS:A total of 57 common targets of QGC and sarcopenia were obtained.Based on the enrichment analysis of GO and KEGG,we took the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt) signaling pathway as a key target to explore the mechanism of QGC on sarcopenia.Animal experiments showed that QGC could increase muscle strength and inhibit muscle fiber atrophy.In the model group,the expression of muscle ring finger-1 and Atrogin-1 were increased,while myosin heavy chain was decreased,QGC treatment reversed these changes.Moreover,compared with the model group,the expressions of pPI3K,p-Akt,p-mammalian target of rapamycin and pForkhead box O3 in the QGC group were all upregulated.CONCLUSION:QGC exerts an anti-sarcopenic effect by activating PI3K/Akt signaling pathway to regulate skeletal muscle protein metabolism.
文摘Naturally degradable capsule provides a platform for sustained fragrance release.However,practical challenges such as low encapsulation efficiency and difficulty in sustained release are still limited in using fragranceloaded capsules.In this work,the natural materials sodium alginate and gelatine are dissolved and act as the aqueous phase,lavender is dissolved in caprylic/capric triglyceride(GTCC)as the oil phase,and SiO_(2) nanoparticles with neutralwettability as a solid emulsifier to form O/W Pickering emulsions simultaneously.Finally,multi-core capsules are prepared using the drop injection method with emulsions as templates.The results show that the capsules have been successfully prepared with a spherical morphology and multi-core structure,and the encapsulation rate of multi-core capsules can reach up to 99.6%.In addition,the multi-core capsules possess desirable sustained release performance,the cumulative sustained release rate of fragrance at 25℃over 49 days is only 32.5%.It is attributed to the significant protection of multi-core structure,Pickering emulsion nanoparticle membranes,and hydrogel network shell for encapsulated fragrance.This study is designed to deliver a new strategy for using sustained-release technology with fragrance in food,cosmetics,textiles,and other fields.
文摘Background:Polycystic ovary syndrome(PCOS)is one of the most common reproductive endocrine metabolic diseases.Combined use of metformin and diane-35 has better curative effect in regulating serum hormone level(LH,FSH,T and E2)than using metformin alone.Traditional Chinese medicine(TCM)can also be used to treat PCOS.According to some studies,the combined use of metformin and diane-35 and TCM have achieved better curative effect than combining metformin and diane-35 in the treatment of patients with PCOS.Methods:Computerized searches of the science,Medline,VIP,Wan Fang and China HowNet(CNKI)databases were conducted to identify eligible randomized controlled trials(RCTs)from the data obtained up to March 1,2022.The Cochrane Collaboration risk of bias tool was used to assess the risk of bias in individual RCTs,and R software(version 4.0.3)was used for data statistical analysis.Results:Nine RCTs involving 1035 patients were included.Comparing to D+M,significant reduce of LH(mean difference[MD]:-1.93,95%confidence interval[CI]:-3.44,-0.42;Unit:U/L P<0.01;I2=89%)、T(MD:-1.44,95%CI-2.59,-0.30;Unit:nmol/L P<0.01;I2=98%)and significant increase of E2(MD:31.43,95%CI 24.54,38.33;Unit:pmol/L P<0.01;I2=96%)were shown in TCM+D+M.Comparing to D+M,TCM+D+M group has higher ovulation rate(RR 1.1495%CI 1.07,1.22;P=0.42;I2=0%)and higher pregnancy rate(RR 1.2995%CI 1.15,1.44;P=0.37;I2=7%).There is no significant difference between the two therapies in FSH changes(MD:-1.00,95%CI-2.27,0.28;Unit:U/L P<0.01;I2=95%).Subgroup analysis showed that compared with the Guizhi Fuling capsule group,the Kuntai capsule group had more FSH reduction and E2 increase more.In other outcome indicators,the two subgroup did not show significant differences.Conclusion:Kuntai Capsule+Diane-35+Metformin is better than Guizhi Fuling Capsule in reducing FSH,and it is also better in increasing E2.There was no significant difference between the two in LH and T hormones.There was no significant difference between Kuntai Capsules+Diane-35+Metformin and Guizhi Fuling Capsules+Diane-35+Metformin.As for the effect in lessen insulin resistance,Kuntai Capsule+Diane-35+Metformin was significantly better than Guizhi Fuling Capsules+Diane-35+Metformin.
文摘In this letter,we comment on a recent article published in the World Journal of Gastroenterology by Xiao et al,where the authors aimed to use a deep learning model to automatically detect gastrointestinal lesions during capsule endoscopy(CE).CE was first presented in 2000 and was approved by the Food and Drug Administration in 2001.The indications of CE overlap with those of regular diagnostic endoscopy.However,in clinical practice,CE is usually used to detect lesions in areas inaccessible to standard endoscopies or in cases of bleeding that might be missed during conventional endoscopy.Since the emergence of CE,many physiological and technical challenges have been faced and addressed.In this letter,we summarize the current challenges and briefly mention the proposed methods to overcome these challenges to answer a central question:Do we still need CE?
文摘BACKGROUND Surveillance colonoscopies are predominantly normal,identifying patients for potential polypectomy is advantageous.AIM To assess colon capsule endoscopy(CCE)and/or faecal immunochemical test(FIT)as filters in surveillance.METHODS Patients aged≥18 due for polyp surveillance were invited for CCE and FIT.Identifying polyps or colorectal cancer resulted in a positive CCE.Significant lesions(≥3 polyps or≥6 mm polyps),incomplete studies and positive FITs(≥225 ng/mL)were referred for endoscopy.CCE and endoscopy results,FIT accuracy and patient preference were assessed.RESULTS From a total of 126 CCEs[mean age 64(31-80),67(53.2%)males),70.6%(89/126)were excreted,86.5%(109/126)had adequate image quality.CCE positivity was 70.6%(89/126),42.9%(54/126)having significant polyps with 63.5%(80/126)referred for endoscopy(19 sigmoidoscopies,61 colonoscopies).CCE reduced endoscopy need by 36.5%(46/126)and 51.6%(65/126)were spared a colonoscopy.CCE positive predictive value was 88.2%(45/51).Significant extracolonic findings were reported in 3.2%(4/126).Patients with positive CCEs were older>65[odds ratio(OR)=2.5,95%confidence interval(CI):1.1517-5.5787,P=0.0159],with personal history of polyps(OR=2.3,95%CI:0.9734-5.4066,P=0.045),with high/intermediate polyp surveillance risk(OR=5.4,95%CI:1.1979-24.3824,P=0.0156).Overall,5/114(4.4%)FITs were positive(range:0-1394 ng/mL,mean:54 ng/mL).Sensitivity(9.6%)and negative predictive values(20.3%)were inadequate.Receiver operating curve analysis gave a sensitivity and specificity of 26.9%and 91.7%,for FIT of 43 ng/mL.Patients preferred CCE 63.3%(76/120),with less impact on daily activities(21.7%vs 93.2%)and time off work(average days 0.9 vs 1.2,P=0.0201).CONCLUSION CCE appears effective in low-risk polyp surveillance.FIT does not appear to be of benefit in surveillance.
文摘Context:In irrigated agriculture,the salt stress is a major problem due to accumulation of salt from the irrigation water in the soil layers.Objectives:The aim of this study is to determinate the effect of salinity on some agromorphological traits and seed nutritional quality of three sesames(Sesamum indicum L.)varieties.Methodology:This is how four solutions of different NaCl concentrations from 0,60,120 to 240 mM were used to water sesame plants at the five-leaves stage and this for two months in completely randomized device with four repetitions.Results:The results show a negative effect of the salinity growth and yield parameters,mineral elements,ascorbic acid(to 21.4% in White cultivar,28% in Brown and 24.2% in Black cultivar from 0 to 240 mM NaCl),oil(to 22.6%in White cultivar,32% in Brown and 25.5% in Black cultivar from 0 to 240 mM NaCl)and accumulation of Na(Sodium)content(to 11.8% in White cultivar,15.3% in Brown and 12.2% in Black cultivar from 0 to 240 mM NaCl),osmolytes as proteins(to 14.5% in White cultivar,11.5% in Brown and 9.6%in Black cultivar from 0 to 240 mM NaCl)and antioxydants components.Varieties White and Brown were less affected by salinity.Conclusion:White variety exhibited higher adaptive potential under salinity stress when compared to Brown variety(rich in fiber)and closely followed by Black variety.Thus White variety could be recommended for consumer oil,minerals and proteins.As for Black variety,it could be used,as glucid and antioxydants additives in food.

文摘Environmentally friendly slow-release fertilizers are highly desired in sustainable agriculture.Encapsulating fertilizers can routinely achieve controlled releasing performances but suffers from short-term effectiveness or environmental unfriendliness.In this work,a bio-derived shellac incorporated with polydodecyl trimethoxysilane(SL-PDTMS)capsule was developed for long-term controlled releasing urea.Due to enhanced hydrophobicity and thus water resistance,the SL-PDTMS encapsulated urea fertilizer(SPEU)demonstrated a long-term effectiveness of 60 d,compared with SL encapsulated urea fertilizer(SEU,30 d)and pure urea fertilizer(U,5 min).In addition,SPEU showed a broad pH tolerance from 5.0 to 9.0,covering most various soil pH conditions.In the pot experiments,promoted growth of maize seedlings was observed after applying SPEU,rendering it promising as a high-performance controlled-released fertilizer.
文摘BACKGROUND Proper antidepressant use can improve mood and reduce desire to drink alcohol in alcohol-induced-affective-disorder patients.Shugan Jieyu capsules(SJC)have various impacts on the central nervous system,producing antidepressant effects.Traditional Chinese medicine(including Shugan Jieyu)is highly therapeutic in treating alcohol dependence,with few side-effects.However,research on its combination with Western antidepressants(e.g.,sertraline)to improve patients’depression is insufficient.AIM To evaluate the clinical efficacy and safety of SJC combined with sertraline vs sertraline monotherapy in alcohol-dependent patients with comorbid depression.METHODS We conducted a randomized,double-blind,placebo-controlled trial.Sixty patients(aged 18-65 years)were randomly assigned to two groups(n=30 per group).Primary outcome:Hamilton Depression Rating Scale(HAMD)-17 changes over 6 weeks.Benzodiazepines were permitted for severe insomnia.RESULTS The HAMD-17 score of the study(vs control)group was lower at treatment weeks 2,4,and 6(P<0.05).Regarding intra-group comparisons,the study group’s HAMD score was significantly lower than that before treatment from week 2(P<0.05),while that of the control group was significantly lower than that before treatment from week 4(P<0.05).The study and control groups’total efficacy rates were 90%and 73.3%,respectively,showing a significant difference in efficacy(χ^(2)=4.812,P=0.028).No significant difference was observed in adverse reactions’incidence between the groups at treatment weeks 2,4,and 6(P>0.05).CONCLUSION SJC-sertraline combination therapy accelerates depressive symptom relief(by 2 weeks)and improves response rates(+16.7%)in alcohol-dependent patients,without increasing adverse events.Clinical outcomes suggest potential synergistic mechanisms,though no biomarker analyses were performed.
