Objective To observe the effects of Danqi Granules combined with Xianling Gubao Capsules on bone metabolism and bone mineral density (BMD) in patients with postmenopausal osteoporotic vertebral compression fractures (OVCF) after surgery. Methods 90 cases of postmenopausal women with OVCF were randomly divided into the control group and the observation group, 45 cases in each group. The two groups were treated by vertebroplasty (PVP), and after the surgery, the control group was treated with Xianling Gubao Capsules while the observation group was additionally given Danqi Granules. The serum markers of bone metabolism [(25 (OH) D, PINP, β-CTX] and BMD of L2-4 and left femoral neck were detected before and after treatment. Results The level of serum 25 (OH) D in the observation group after treatment was significantly higher while the levels of PINP and β-CTX were significantly lower than those in the control group (P<0.05), and the BMD of L2-4 and left femoral neck of the observation group were significantly higher than those of the control group (P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups. Conclusion Danqi Granules combined with Xianling Gubao Capsules can significantly accelerate fracture recovery, and improve bone mineral density in the treatment of postmenopausal women with OVCF.

Objective To investigate the effects of angiotensin Ⅱ (Ang Ⅱ) on the expression of TLR4 and its role in lipopolysaccharide (LPS)-induced NF-κB activation and CD40 expression in rat peritoneal mesothelial cells (RPMCs). Methods RPMCs were harvested from Spragne-Dawley rat peritoneal cavity and maintained under defined in vitro condition. The cells were treated with Ang Ⅱ at different concentrations (10-9, 10-8, 10-7, 10-6 mol/L) and exposed to Ang Ⅱ (10-7 mol/L) for different times (1, 2, 4, 8, 12, 24, 48 h for mRNA and 6, 12, 24, 36, 48 h for protein, respectively). Meanwhile, the influence of AT1 receptor antagonist (AT1R, losartan, 10-5 mol/L) and AT2 receptor blocker (AT2R, PD123177, 10-5 mol/L) on the TLR4 induced by Ang Ⅱ was observed. After synchronization for 24 hours, the cells were randomly assigned to four groups: the control group, the Ang Ⅱ (10-7 tool/L) group, the LPS (1 mg/L) group, the Ang Ⅱ (10-7 mol/L) plus LPS (1 mg/L) group, which were used to investigate the effects of Ang Ⅱ on the NF-κB activation and CD40 expression induced by LPS. The mRNA expression of TLR4 and CD40 was measured by RT-PCR and the protein abundance of TLR4, NF-κB p65, phospho-p65, IKBα and phospho-IκBα were analyzed by Western blot. Immunofluorescence was performed to determine the subcellular localization of p65 subunit of NF-κB. Results (1) Treatment of RPMCs with Ang Ⅱ resulted in a concentration-dependent increase in the expression of TLR4. Ang Ⅱ at 10-9, 10-8, 10-7 and 10-6 mol/L increased TLR4 mRNA expression by 70.5%, 89.5%, 102.9%, and 121.9%, respectively and protein expression by 12.1%, 27.7%, 51.2%, and 41.6%, respectively (P<0.01). Treatment of RPMCs with 10-7 mol/L Ang Ⅱ resulted in a time-dependent increase in the expression of TLR4, with the peak of mRNA expression at 8 and 12 h (P<0.01) and the protein expression at 12 and 24 h (P<0.01). (2) Losartan antagonized Ang Ⅱ-stimulated expression of TLR4 by 33.5% (P<0.05), PD123177 had no such effect (P0.05). (3) Treatment of RPMCs with LPS (1 mg/L) for 60 rain significantly increased the ratio of phospho-IκBα to IκBα by 362.6% (P< 0.01) , phospho-p65 to p65 by 67.4% (P<0.05), and LPS (1 mg/L) for 4 h significantly increased the expression of CD40 mRNA by 299.9% (P<0.01) compared to the control group. In comparison to the LPS (1 mg/L) group, preincubation of RPMCs with AngⅡ (10-7 mol/L) for 24 h then treated with LPS (1 mg/L) for 60 rain significantly increased the ratio of phospho-IκBα to IκBα by 49.1% (P<0.01), phospho-p65 to p65 by 29.3%(P<0.05), and LPS (1 mg/L) for 4 h significantly increased the expression of CD40 mRNA by 56.8%(P<0.01). (4) The p65 subunit of NF-κB was dominantly distributed in the cytoplasm in the control and Ang Ⅱ group. Following exposure to LPS for 60 min, p65 subunit labeling was upregulated and translocated into the nuclei. A significantly increased nuclear staining of p65 in ceils treated with Ang Ⅱ plus LPS were observed. Conclusions Ang Ⅱ induces the expression of TLR4 in dose- and time-dependent manner in RPMCs, resulting in enhanced NF-κB signaling and induction of CD40 expression, Locally produced Ang Ⅱ in the peritoneum may play an amplified role in LPS-induced peritoneal inflammation.

A total of 60 non-acupuncture master postgraduates were divided into control class and experimental class randomly, 30 postgraduates in each class. The control class was taught by traditional teaching methods and experimental class was taught by new teaching methods. The test was conducted after one month later. All the scores were analyzed by SPSS17.0. The result showed that the oretical score ,the practical score and disease recognition rates in the experimental class were significantly higher than those in the control class (P<0.05). The questionnaires showed experimental class had obvious advantage than control class (P<0.05). The new teaching methods of acupuncture has obvious advantage than traditional teaching methods and can provide a new way for teaching acupuncture during resident standardization training.

Under the background of dual-track training mode, the current clinical program of professional master's graduate education lacks complete and unified content and requirements. We set out a unified teaching scheme of subspecialty, in the main subject acupuncture. We identified the teaching management and innovated the teaching and examination methods in the scheme. Our research gradually formed a multidisciplinary talents training system, as the foundation of developing the standardization training. This method could help to cultivate qualified graduates as the high quality talents for the national medicine development.

In order to observe the effect of Bushenantai recipe on the expression of endometrial leukemia-inhibitory factor (LIF) in mice with embryonic implantation dysfunction (EID), 120 Kunming mice post coition were randomized into three groups: normal control group, model group and traditional Chinese medicine group (TCM group) (n=40 in each group). Uterus was collected on the pregnancy day (Pd) 4, 5, 6 after an intravenous injection of Evan's blue. The endometrium was dyed by Evan's blue and the mean points of response were observed on Pd 5. The expression of LIF mRNA and protein was detected by RT-PCR and immunohistochemistry respectively and analyzed statistically by image system. The results showed that the number of implantation sites in model group was remarkably less than in normal control group and TCM group. There was no significant difference between normal control group and TCM group. The expression of LIF mRNA and protein in model group was delayed. Bushenantai recipe could increase the expression of LIF mRNA and protein in endometria of mice with EID. It was suggested that Bushenantai recipe could improve embryo implantation of mice with EID by promoting the endometrial LIF expression and endometrial decidualization.

Methods Patients were recruited from January 1, 2014, until December 31, 2015, in the Hematology hematopoietic stem cell transplantation ward. Thiry-two patients were recruited in the control group. Ninety patients wererecruited in the experience group. They were randomly assigned to three groups with 30 cases each, extracting different amounts of itraconazole before infusion, back phlebotomize in group A, B, C respectively was 10.0, 0.5, 1.0 ml. Comparing the phlebitis and obstruction after ten days from the transfusion day on. Results Catheter obstruction was not observed in any case. There was a significant difference between control group (21.9%,7/32) and observation group (0) regarding the incidence of phlebitis (χ2=21.157,P < 0.05). No statistical difference was noted among the observation groups regarding the incidence of phlebitis (P>0.05). Conclusions Drawing a small amount of blood volume before itraconazole injection through PICC can effectively avoid the drug-induced catheterobstruction. What′s more, transfusion through PICC can significantly reduce the incidence of phlebitis compared with peripheral infusion.

BACKGROUND: A large number of experiments in vivo and in vitro have shown that mesenchymal stem cells may obviously inhibit the lymphocytes and other immunocytes.OBJECTIVE: To investigate the effect of human umbilical cord mesenchymal stem cell transplantation on the immune function and prognosis of patients suffering decompensated liver cirrhosisn due to hepatitis B.METHODS: 118 patients with decompensated cirrhosis due to hepatitis B were randomly divided into control group (n=59) and observation group (n=59). The two groups all received normal medical treatment, and in addition, the observation group also received human umbilical cord mesenchymal stem cell transplantation. (4.0-4.5)×108 stem cells were transplanted twice by intervention via proper hepatic artery (10 mL) and intravenous infusion (10 mL) within 1 week after admission. The levels of serum interleukin-6, tumor necrosis factor-α, interleukin-10, transforming growth factor-β and the percentage of lymphocyte subsets in the peripheral blood were determined in the two groups before and 1, 4 weeks after treatment. The model for end-stage liver disease (MELD) score and Child-Pugh score of 118 patients after treatment for 12 weeks were observed and recorded, and liver failure, complications and survival during follow-up period in the two groups were observed. RESULTS AND CONCLUSION: After treatment for 1 and 4 weeks, the levels of serum interleukin-6 and tumor necrosis factor-α in the observation group were significantly lower than those in the control group (P < 0.05 or P <0.001), but the levels of serum interleukin-10 and transforming growth factor-β in the observation group were significantly higher than those in the control group (P < 0.05 or P < 0.001). After treatment for 1 week, the percentagesof CD3+CD4+T cell and CD4+CD25+Treg cells in the observation group were significantly higher than those in the control group (P < 0.001), but the percentages of CD3+CD8+ T cells and CD3-CD19+ B cells were significantly lower than those in the control group (P < 0.05 or P < 0.001). After treatment for 4 weeks, the percentages of CD3+ T cell ,CD3+CD4+ T cells and CD4+CD25+ Treg cells in the observation group were significantly higher than those in the control group (P < 0.05 or P < 0.001), but the percentages of CD3+CD8+ T cell and CD3-CD19+ B cells were significantly lower than those in the control group (P < 0.05 or P < 0.001). After treatment for 12 weeks, the MELD and Child-Pugh scores in the observation group were significantly lower than those in the control group (P < 0.05).During the follow-up period, none of the cases in the observation group developed liver failure, but five cases in the control group did. In addition, the incidence of complications and cumulative mortality in the observation group were significantly lower than those in the control group (P < 0.05). These results show that the human umbilical cord mesenchymal stem cell transplantation may alleviate liver inflammation and improve liver function, and then may reduce the incidence of hepatic failure and mortality for patients with decompensated cirrhosis due to hepatitis B.

Objective: To compare the effectiveness of qualitative and quantitative fecal immunochemical tests (FIT) in identifying colorectal cancer, so as to provide insights into perfecting screening strategies for colorectal cancer. Methods: Participants in the Colorectal Cancer Screening Program for Key Populations in Zhejiang Province from May 2020 to December 2021 were recruited, and their demographic information, lifestyle and disease history were collected through a questionnaire survey. Qualitative or quantitative FIT along with a questionnaire-based risk assessment were employed as the initial screening tests. Individuals who were positive in any FIT or had high-risk assessment results were required to attend a subsequent colonoscopy examination. The positive rate, detection rate of colorectal cancer, positive predictive value and number of colonoscopies required were compared between qualitative and quantitative FITs, and stratified analyses by gender and age were conducted. Results: Totally 4 099 769 participants were included. The qualitative FIT group included 3 574 917 individuals, yielding a positive rate of 11.35%, a detection rate of 1.19%, a positive predictive value of 0.48% and 83.84 colonoscopies required to detect one cancer case. The quantitative FIT group involved 524 852 individuals, yielding a positive rate of 6.70%, a detection rate of 2.31%, a positive predictive value of 1.01% and 43.23 colonoscopies required to detect one cancer case. The quantitative FIT group showed significantly higher detection rate of colorectal cancer, higher positive predictive value and less number of colonoscopies required compared to the qualitative FIT group (all P<0.05). The same results were obtained after stratification by gender and age. Conclusion Compared to qualitative FIT, quantitative FIT improves the detection of colorectal cancer and reduces the workload of colonoscopy examinations, making it more suitable for colorectal cancer screening in large-scale populations.
