Methods: A total of 100 patients with gastrointestinal reactions who were hospitalized in the oncology department of Nanning Third People’s Hospital from January to December 2023 were selected as study subjects. They were randomly divided into two groups: the observation group (n = 50) received standard antiemetic treatment in conjunction with Shen-Shi Zhi-Tong plaster and Lei-Huo moxibustion, while the control group (n = 50) received only standard antiemetic treatment and Lei-Huo moxibustion. The occurrence of nausea and vomiting during chemotherapy was recorded using a CINV nursing log, and the incidence rates of acute and delayed vomiting were statistically analyzed. Results: The incidence rate of acute vomiting in the observation group was 42%, significantly lower than the control group’s 64% (P = 0.0300);the incidence rate of delayed vomiting was 36% in the observation group compared to 48% in the control group (P = 0.1900). The mean nausea grade in the observation group was 1.08, significantly lower than 2.02 in the control group (P Conclusion: Shen-Shi Zhi-Tong plaster combined with Lei-Huo moxibustion can effectively reduce the incidence of nausea and vomiting in patients undergoing highly emetogenic chemotherapy and shows good clinical application prospects. This study provides strong support for the adoption of such combined therapies in the prevention and treatment of CINV in the future.展开更多

The clinical therapeutic efficacy and hematologic parameters in patie nts were observed, and systemic gene analysis was conducted with PAGE, PCR, PCR SSCP, RT PCR and DNA sequences analysis and mRNA detection, in order to s tudy the molecular mechanism from the relationships between genetic mutation and clinical efficacy, gene expression and its regulation. Results: YSSXL showed obvious therapeutic effect in treating β thalassemia. Gene analysis revealed that it did not change the genetic mutatio n type, but could obviously increase hemoglobin, fetal hemoglobin (HbF), γ/(β+ γ) globin ratio, γ globin mRNA expression and GM CSF mRNA expression in patients, as well as the GM CSFmRMA in marrow of mice after 60 Co radia tion. Conclusion: YSSXL has a remarkable therapeutic effect on β tha lassemia, and its possible mechanism is its action in unlocking γ gene, in creasing the γ globin expression and enhancing HbF synthesis so as to compe nsate for the gene defect. This study has opened a new path for the treatment of β thalassemia with TCM.展开更多

Based on the chromatographic retention behavior, fragmentation patterns of chemical components, published literatures, and literature databases, an UPLC-Q-TOF/MS(LC-TOF/MS) method was established to identify the components of ZSP and its metabolites in biological samples. A total of 101 compounds were identified and tentatively characterized from the ZSP, including alkaloids, xanthones, and timosaponins. Except for 33 prototype components, 22 metabolites were detected in the plasma, urine, and prostate, and mainly came from Phellodendri Amurensis Cortex and Anemarrhenae Rhizoma. It was found that glucuronidation and sulfation were the major metabolic processes of xanthones, while oxidation, demethylation, and glucuronidation were the major metabolic pathways of alkaloids. In summary, the present study provided important chemical information on the metabolism of ZSP, indicating that alkaloids might be able to be absorbed into the prostate. The results provided a basis for further studies of the mechanisms of action for ZSP.展开更多

By selecting the Shen-Dong coal mining subsidence area as the research field, this paper studies the changes in precipitation infiltration recharge in the circumstances of coal mining subsidence by means of field geological investigation and laboratory simulation experiments, which is expected to provide a scientific basis for eco-environmental restoration in the mining area. The results indicate that at the unstable stage of subsidence, three types of subsidence in the Shen-Dong mining area have positive effects on the precipitation infiltration recharge, and the type of full-thickness bedrock subsidence has the greatest influence. In the stable stage of subsidence, the precipitation infiltration process after long- term drought and the moisture migration in the aeration zone undergo three different stages： evaporation-infiltration before precipitation, infiltration-upward infiltration-infiltration during precipitation and evaporation-infiltration after precipitation. During a heavy rainfall infiltration process, the wetting front movement in fine sand, coarse sand and dualistic structure of fine-coarse sand consists of two stages： the stage of wetting front movement during precipitation, in which the wetting front movement distance has linear relationship with the depth, and the stage of wetting front movement after precipitation, in which the wetting front movement distance has the power function relationship with the depth. The wetting front movement velocity is influenced by the rainfall amount and the lithology in the aeration zone. However, as the depth increases, the movement velocity will decay exponentially.展开更多

The COH implantation dysfunction model in ...The effect and underlying mechanism of Bu-Shen-An-Tai recipe on ovarian apoptosis in mice with controlled ovarian hyperstimulation(COH) implantation dysfunction were studied. The COH implantation dysfunction model in mice was established by intraperitoneal injection of 7.5 IU pregnant mare’s serum gonadotrophin(PMSG), followed by 7.5 IU human chorionic gonadotrophin(HCG) 48 h later. Then the female mice were mated with male at a ratio of 2:1 in the same cage at 6:00 p.m. The female mice from normal group were injected intraperitoneally with normal saline and mated at the corresponding time. Day 1 of pregnancy was recorded by examining its vaginal smears at 8:00 a.m. of the next day. Fifty successfully pregnant mice were equally randomly divided into 5 groups: normal control pregnant group(NC), COH implantation dysfunction model group(COH), low dosage of Bu-Shen-An-Tai recipe group(LOW), middle dosage of Bu-Shen-An-Tai recipe group(MID) and high dosage of Bu-Shen-An-Tai recipe group(HIGH). Then from day 1, the mice in different groups were respectively intragastrically given corresponding treatments at 9:00 a.m. for 5 consecutive days. The concentrations of 17β-estradiol(E) and progesterone(P) were determined by radioimmunoassay(RIA). The ultrastructural changes of ovarian tissues were observed by transmission electron microscope(TEM). The histopathological changes of ovarian tissues were observed by HE staining. The number of atretic follicles and pregnant corpus luteum were also recorded. TUNEL was applied to measure apoptotic cells of ovarian tissues. Western blotting was used to detect the protein expression of apoptosis-related factors like Bax, Bcl-2 and cleaved-caspase-3 in ovarian tissue of mice. The results showed that ovarian weight, the concentrations of Eand P, the number of atretic follicles and pregnant corpus luteum, as well as the apoptosis of granulosa cells were significantly increased in the COH group. The ultrastructures of ovarian tissues in the COH group showed that chromatin in granulosa cells was increased, agglutinated, aggregated or crescent-shaped. The focal cavitation and the typical apoptotic bodies could be seen in granulosa cells in the late stage of apoptosis. After the treatment with different doses of Bu-Shen-An-Tai recipe, the ultrastructural changes of ovarian granulosa cells apoptosis were dramatically improved and even disappeared under TEM. Visible mitochondria and mitochondrial cristae were increased and vacuoles were significantly reduced. The lipid dropltes were shown in a circluar or oval shape. The protein expression levels of Bax and cleaved-caspase-3 were decreased, and the expression of Bcl-2 protein was increased after treatment. It was concluded that Bu-Shen-An-Tai recipe can inhibit the apoptosis of ovarian granulosa cells, probably by up-regulating the protein expression of Bcl-2 and down-regulating Bax and cleaved-caspase-3, which contributes to the formation and maintenance of ovarian corpus luteum. It’s helpful to promote the embryonic implantation, to reduce embryo loss and ultimately to improve the success rate of pregnancy.展开更多

METHODS: In this study, we carried out gavage with SZL oral solution in an APP/PS-1 heterozygous double transgenic AD mouse model for 12 continuous weeks. Haematoxylin and eosin staining, Nissl staining and Annexin V/Propidium Iodide staining were used to detect the brain histopathology in AD mouse model. Immunofluorescence staining was used to detect the expression levels of autophagy's proteins. Morris water maze test was used to detect the learning and memory ability in AD mouse model. RESULTS: Pathological results showed that neuronal loss in the hippocampus of mice in the SZL intervention group was significantly alleviated and the number of apoptotic neurons was significantly decreased compared with the control group (physiological saline and non-intervention groups). Immunofluorescence staining results showed that the expression of autophagy activators, Beclin-1 and LC3B, was significantly increased in the hippocampal neurons of mice of the SZL intervention group, while the expression of the apoptotic factor, caspase- 3, was significantly decreased. At the same time, hippocampal accumulation of Aβ42 protein was significantly decreased. In addition, results of the water maze experiment showed that the latency period in mice from the SZL intervention group was significantly reduced. CONCLUSION: In summary, we believe that the SZL oral solution significantly activates autophagy in hippocampal neurons, effectively reducing the accumulation of Aβ42 peptides, alleviating neuronal injury and apoptosis, and ultimately improving the cognitive function in a mouse model of AD.展开更多

Methods: Sixty patients with AD were divided into 3 groups according to their MMSE and ADL scores before treatment, using randomized block design. They were treated separately with TXR, BSR and Donepezil (Dp) for 12 weeks. The changes of MMSE score, ADL score, neuro-psychology amount table score, including FOM, RVR, DS and BD, as well as the overall operational evaluation before and after treatment were analyzed. Results: The recognition and daily life capacity of patients in the 3 groups were improved after treatment. MMSE score in the TXR group increased from 16.10±1.94 scores before treatment to 17 90±2 59 scores after treatment, in the BSR group, from 16 15±2 16 to 17 50±2 59, and in the Dp group, from 17 35±1 90 to 19 60±3 39, all showed significant difference (all P<0 01). Change of ADL score showed that in the TXR group, it lowere d from 43 10±3 86 to 41 50±4 40, in the BSR group from 43 30±4 53 to 41 60±4 12 and in the Dp group, from 42 95±3 58 to 40 60±5 23, which also showed significan t difference (P<0 05 or P<0 01). Moreover, increase of FOM, RVR and DS score was shown in the TXR and the Dp group, and increase of RVR and BD score was shown in the BSR group, with significant difference in compar ison of corresponding score before and after treatment, inter-groups comparison showed significant difference of FOM score between the BSR and the Dp group ( P<0 01). Overall operational evaluation (total effective rate) in the TXR group was 70%, in the BSR group 65% and in Dp group 75%, with no significant difference among them. Conclusion: TXR and BSR are effective TCM drugs in treating AD展开更多

It was found that glucuronidation and sulfation were the major metabolic processes of xanthones, while oxidation, demethylation, and glucuronidation were the major metabolic pathways of alkaloids. In summary, the present study provided important chemical information on the metabolism of ZSP, indicating that alkaloids might be able to be absorbed into the prostate. The results provided a basis for further studies of the mechanisms of action for ZSP.

文摘Coal mining subsidence is a universal environmental-geological problem in mining areas. By selecting the Shen-Dong coal mining subsidence area as the research field, this paper studies the changes in precipitation infiltration recharge in the circumstances of coal mining subsidence by means of field geological investigation and laboratory simulation experiments, which is expected to provide a scientific basis for eco-environmental restoration in the mining area. The results indicate that at the unstable stage of subsidence, three types of subsidence in the Shen-Dong mining area have positive effects on the precipitation infiltration recharge, and the type of full-thickness bedrock subsidence has the greatest influence. In the stable stage of subsidence, the precipitation infiltration process after long- term drought and the moisture migration in the aeration zone undergo three different stages： evaporation-infiltration before precipitation, infiltration-upward infiltration-infiltration during precipitation and evaporation-infiltration after precipitation. During a heavy rainfall infiltration process, the wetting front movement in fine sand, coarse sand and dualistic structure of fine-coarse sand consists of two stages： the stage of wetting front movement during precipitation, in which the wetting front movement distance has linear relationship with the depth, and the stage of wetting front movement after precipitation, in which the wetting front movement distance has the power function relationship with the depth. The wetting front movement velocity is influenced by the rainfall amount and the lithology in the aeration zone. However, as the depth increases, the movement velocity will decay exponentially.

文摘The effect and underlying mechanism of Bu-Shen-An-Tai recipe on ovarian apoptosis in mice with controlled ovarian hyperstimulation(COH) implantation dysfunction were studied. The COH implantation dysfunction model in mice was established by intraperitoneal injection of 7.5 IU pregnant mare’s serum gonadotrophin(PMSG), followed by 7.5 IU human chorionic gonadotrophin(HCG) 48 h later. Then the female mice were mated with male at a ratio of 2:1 in the same cage at 6:00 p.m. The female mice from normal group were injected intraperitoneally with normal saline and mated at the corresponding time. Day 1 of pregnancy was recorded by examining its vaginal smears at 8:00 a.m. of the next day. Fifty successfully pregnant mice were equally randomly divided into 5 groups: normal control pregnant group(NC), COH implantation dysfunction model group(COH), low dosage of Bu-Shen-An-Tai recipe group(LOW), middle dosage of Bu-Shen-An-Tai recipe group(MID) and high dosage of Bu-Shen-An-Tai recipe group(HIGH). Then from day 1, the mice in different groups were respectively intragastrically given corresponding treatments at 9:00 a.m. for 5 consecutive days. The concentrations of 17β-estradiol(E) and progesterone(P) were determined by radioimmunoassay(RIA). The ultrastructural changes of ovarian tissues were observed by transmission electron microscope(TEM). The histopathological changes of ovarian tissues were observed by HE staining. The number of atretic follicles and pregnant corpus luteum were also recorded. TUNEL was applied to measure apoptotic cells of ovarian tissues. Western blotting was used to detect the protein expression of apoptosis-related factors like Bax, Bcl-2 and cleaved-caspase-3 in ovarian tissue of mice. The results showed that ovarian weight, the concentrations of Eand P, the number of atretic follicles and pregnant corpus luteum, as well as the apoptosis of granulosa cells were significantly increased in the COH group. The ultrastructures of ovarian tissues in the COH group showed that chromatin in granulosa cells was increased, agglutinated, aggregated or crescent-shaped. The focal cavitation and the typical apoptotic bodies could be seen in granulosa cells in the late stage of apoptosis. After the treatment with different doses of Bu-Shen-An-Tai recipe, the ultrastructural changes of ovarian granulosa cells apoptosis were dramatically improved and even disappeared under TEM. Visible mitochondria and mitochondrial cristae were increased and vacuoles were significantly reduced. The lipid dropltes were shown in a circluar or oval shape. The protein expression levels of Bax and cleaved-caspase-3 were decreased, and the expression of Bcl-2 protein was increased after treatment. It was concluded that Bu-Shen-An-Tai recipe can inhibit the apoptosis of ovarian granulosa cells, probably by up-regulating the protein expression of Bcl-2 and down-regulating Bax and cleaved-caspase-3, which contributes to the formation and maintenance of ovarian corpus luteum. It’s helpful to promote the embryonic implantation, to reduce embryo loss and ultimately to improve the success rate of pregnancy.

文摘OBJECTIVE: To investigate the effector mechanisms and effector targets of Shen-Zhi-Ling (SZL) oral solution in the treatment of Alzheimer's disease (AD). METHODS: In this study, we carried out gavage with SZL oral solution in an APP/PS-1 heterozygous double transgenic AD mouse model for 12 continuous weeks. Haematoxylin and eosin staining, Nissl staining and Annexin V/Propidium Iodide staining were used to detect the brain histopathology in AD mouse model. Immunofluorescence staining was used to detect the expression levels of autophagy's proteins. Morris water maze test was used to detect the learning and memory ability in AD mouse model. RESULTS: Pathological results showed that neuronal loss in the hippocampus of mice in the SZL intervention group was significantly alleviated and the number of apoptotic neurons was significantly decreased compared with the control group (physiological saline and non-intervention groups). Immunofluorescence staining results showed that the expression of autophagy activators, Beclin-1 and LC3B, was significantly increased in the hippocampal neurons of mice of the SZL intervention group, while the expression of the apoptotic factor, caspase- 3, was significantly decreased. At the same time, hippocampal accumulation of Aβ42 protein was significantly decreased. In addition, results of the water maze experiment showed that the latency period in mice from the SZL intervention group was significantly reduced. CONCLUSION: In summary, we believe that the SZL oral solution significantly activates autophagy in hippocampal neurons, effectively reducing the accumulation of Aβ42 peptides, alleviating neuronal injury and apoptosis, and ultimately improving the cognitive function in a mouse model of AD.
文摘Objective: To explore the therapeutic mechanism of Tiaoxin Recipe and Bushen Recipe (BSR, ) in treating Alzheimer’s d isease (AD). Methods: Sixty patients with AD were divided into 3 groups according to their MMSE and ADL scores before treatment, using randomized block design. They were treated separately with TXR, BSR and Donepezil (Dp) for 12 weeks. The changes of MMSE score, ADL score, neuro-psychology amount table score, including FOM, RVR, DS and BD, as well as the overall operational evaluation before and after treatment were analyzed. Results: The recognition and daily life capacity of patients in the 3 groups were improved after treatment. MMSE score in the TXR group increased from 16.10±1.94 scores before treatment to 17 90±2 59 scores after treatment, in the BSR group, from 16 15±2 16 to 17 50±2 59, and in the Dp group, from 17 35±1 90 to 19 60±3 39, all showed significant difference (all P<0 01). Change of ADL score showed that in the TXR group, it lowere d from 43 10±3 86 to 41 50±4 40, in the BSR group from 43 30±4 53 to 41 60±4 12 and in the Dp group, from 42 95±3 58 to 40 60±5 23, which also showed significan t difference (P<0 05 or P<0 01). Moreover, increase of FOM, RVR and DS score was shown in the TXR and the Dp group, and increase of RVR and BD score was shown in the BSR group, with significant difference in compar ison of corresponding score before and after treatment, inter-groups comparison showed significant difference of FOM score between the BSR and the Dp group ( P<0 01). Overall operational evaluation (total effective rate) in the TXR group was 70%, in the BSR group 65% and in Dp group 75%, with no significant difference among them. Conclusion: TXR and BSR are effective TCM drugs in treating AD
