This article presents the design of a bioreactor using hollow fiber membrane and, isolated hepatocytes of suckling pigs, and the experimental study of its efficacy in vitro. Liver cells were harvested from suckling pigs with collagenase perfusion in situ, and parenchymal and non-parenchymal hepatocytes were cocultured in a hollow fiber module which was rotated sporadically. Bioartificial liver(BAL) was developed using this bioreactor,and the BAL was perfused with ascites of patients suffering from liver cirrhosis. The yield of viable hepatocytes was (6.29 +/- 0.37) x 10(8) cells, and cell viability was greater than 84%. Hepatocytes aggregated to multi-cells spheroids after being rotated every thirty minutes for three hours. The hepatocytes in the bioreactor could synthesize urea. Total billirubin was decreased, and AST was significantly increased in the group of bioreactor, as compared with that in the control group. Glucose decreased in the group of bioreactor,whereas there was no significant descent in the control group; and the difference between the two groups was significant. The above results demonstrate that this bioreactor is effective for decreasing total bilirubin and glucose.

Objective:
To analyze the mental health status and its impact factors among nurses, finding ways to improve the mental health of nurses.
Methods:
A total of 13 425 female healthcare workers aged from 18 to 65 were selected as study objects. The survey was conducted with unified design questionnaire. The survey included the basic situation of the individuals and SCL-90 questionnaire. Comparing the female doctors, the mental health status and its impact factors of nurses were analyzed.
Results:
The income, age, education and occupation, which include shift work, heavy work load and overtime work are different between nurses and doctors. The main mental health problems of nurses were obsessive-compulsive symptoms, depressive symptoms and somatization. The results of univariate analysis indicated that shift work, overtime work, and heavy work load affected the positive rate of each factor. The results of multivariate analysis showed that occupation, shift work, overtime work, and heavy work load have significant adverse effects on the positive rate of the total score in female healthcare workers (

Objective:To evaluate the efficacy of Baduanjin combined with mecobalamin tablets in the treatment of type 2 diabetic peripheral neuropathy. Methods:Eighty patients with type 2 diabetic peripheral neuropathy who met the inclusion criteria were randomly divided into two groups with 40 patients in each group ( n=40). The control group took oral mecobalamin tablets and self-management, and the treatment group were treated with Baduanjin on the basis of the control group. All patients were treated for 12 weeks. The clinical symptoms were evaluated by Toronto Clinical Scoring System (TCSS), and the motor nerve conduction velocity (MCV) of tibial nerve and the sensory conduction velocity (SCV) of superficial peroneal nerve were measured by EMG evoked potential instrument. The hemorheological indexes (whole blood low shear viscosity, whole blood high shear viscosity and plasma viscosity) were measured before and after treatment. The clinical efficacy was evaluated and adverse events were recorded. Results:In the course of treatment, 39 patients in each group completed the study with each one dropout. The total effective rate was 87.2% (34/39) in the treatment group and 64.1% (25/39) in the control group. There was significant difference between the two groups ( χ2=5.64, P=0.018). After treatment, the TCSS score of the treatment group was significantly lower than that of the control group ( t=-6.23, P<0.01), the tibial nerve MCV (43.06 ± 4.19 m/s vs. 39.55 ± 4.30 m/s, t=3.65), the superficial peroneal nerve SCV (43.23 ± 4.31 m/s vs. 39.92 ± 3.74 m/s, t=3.62) in the treatment group were significantly higher than the control group ( P<0.001), while the whole blood high shear viscosity, the whole blood low shear viscosity, and the plasma viscosity in the treatment group were significantly lower than the control group ( t value were -10.36, -14.21, -13.88, all Ps<0.001). During the treatment, no serious adverse events occurred in both groups. Conclusion:Baduanjin combined with mecobalamin tablets in the treatment of type 2 diabetic peripheral neuropathy can reduce blood viscosity, promote blood circulation, increase nerve conduction velocity, improve clinical symptoms and signs, and improve clinical efficacy.

Objective:To evaluate the efficacy of Qinggan Bupi Jiangtang Decoction combined with western medicine in the treatment of adult type 2 diabetes mellitus (T2DM) with with liver hyperactivity and spleen deficiency syndrome.Methods:Prospective cohort study. A total of 103 T2DM patients with liver hyperactivity and spleen deficiency syndrome in the Department of endocrinology of Shanghai Municipal Hospital of Traditional Chinese Medicine from February 2020 to February 2021 were randomly divided into the observation group (52 cases) and the control group (51 cases) according to random number table method. Both groups were treated with conventional western medicine, the control group was treated with sitagliptin phosphate on the basis of routine treatment, and the observation group was treated with Qinggan Bupi Jiangtang Decoction on the basis of routine treatment. Both groups were treated for 12 weeks. TCM symptom scores were performed before and after treatment. The FPG, 2hPBG, HbA1c and fasting insulin (FINS) were detected by dry chemistry method and Roche electroluminescence method, and insulin resistance index (HOMA-IR) was calculated. The clinical efficacy was evaluated by dynamic blood glucose monitoring indexes TIR (percentage of time when glucose was in the range of 3.9-10.0 mmol/L), TAR (percentage of time when glucose was higher than the target range ≥ 11.1 mmol/L) and TBR (percentage of time when glucose was lower than the target range <3.9 mmol/L).Results:The total effective rate was 92.3% (48/52) in the observation group and 56.9% (29/51) in the control group ( χ2=15.32, P<0.01). The score of TCM syndrome in the observation group was significantly lower than that of the control group ( t=6.30, P<0.01). The compliance rate of HbA1c in the observation group was 46.2% (24/52) and that of the control group was 23.5% (12/51). There was significant difference between the two groups ( χ2=5.80, P=0.016). Compared with the groups before treatment, MAGE, TAR, TBR significantly decreased and TIR significantly increased in both groups after treatment ( P<0.01), but there was no significant difference between the two groups after treatment ( t values were 0.78, 1.06, 0.22 and 1.45, respectively, P>0.05). Compared with the groups before treatment, the levels of FPG, 2 hPBG and HbA1c in the two groups significantly decreased after treatment ( P<0.01), but there was no significant difference between the two groups after treatment ( t values were 1.32, 0.18,1.50, respectively, P>0.05). Compared with the groups before treatment, the levels of FINS and HOMA-IR in the two groups significantly decreased after treatment ( P<0.01), but there was no significant difference between the two groups after treatment ( t values were 1.25, 0.51, respectively, P>0.05). There were no adverse reactions in the observation group, 2 cases of mild nausea and 1 case of transient diarrhea in the control group. There was no significant difference between the two groups ( χ2=3.15, P=0.118). Conclusion:Qinggan Bupi Jiangtang Decoction combined with routine treatment can improve the blood glucose level, TIR and blood glucose standard rates of adult T2DM with liver hyperactivity and spleen deficiency syndrome, and the curative effect is equivalent to sitagliptin phosphate tablets.

Objective:To investigate the effects of external application of Sanying Plaster on the size of thyroid nodules and the states of depression and anxiety in patients with benign thyroid nodules.Methods:A randomized controlled trial was conducted. A total of 120 patients with benign thyroid nodules from the outpatient clinic of the Department of Thyroid Diseases at Shanghai Traditional Chinese Medicine Hospital from June to December 2022 were selected as the subjects of the study. They were divided into two groups using the random number table method, with 60 patients in each group. The control group received lifestyle intervention treatment, while the treatment group received Sanying Ointment in addition to the treatment of the control group. Both groups were treated for 3 months. TCM syndrome scores were measured before and after treatment; the maximum diameter of thyroid nodules was measured using a color Doppler ultrasound transverse section; the quality of life was assessed using the short form 36 (SF-36); the degree of anxiety and depression was evaluated using the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS); adverse reactions during the treatment period were recorded, and the clinical efficacy was evaluated.Results:During the treatment period, 4 cases in the treatment group and 3 cases in the control group did not complete the treatment. Finally, 56 cases in the treatment group and 57 cases in the control group entered the efficacy evaluation. The total effective rate of the treatment group was 71.4% (40/56), and that of the control group was 14.0% (8/57), with a statistically significant difference between the two groups ( χ2=26.82, P<0.001). After treatment, the TCM syndrome score of the treatment group (10.02±3.65 vs. 16.65±3.44, t=-10.24) was lower than that of the control group ( P<0.001); the maximum diameter of thyroid nodules [11.00 (4.65, 19.93) mm vs. 15.00 (7.15, 28.50) mm, Z=-2.43] was lower than that of the control group ( P<0.05); the SF-36 score [121.83 (117.00, 130.00) vs. 114.42 (104.25, 127.50), Z=-2.62] was higher than that of the control group ( P<0.01); the SDS (46.72±4.59 vs. 57.02±5.99, t=14.80) and SAS (42.25±5.72 vs. 50.60±7.12, t=10.04) scores were lower than those in the control group ( P<0.001). The incidence of adverse reactions during the treatment period in the treatment group was 3.5% (2/57), and no adverse reactions occurred in the control group. Conclusion:The external application of Sanying Ointment helps to reduce the size of thyroid nodules in patients with benign thyroid nodules, improve the quality of life and anxiety and depression, and increase clinical efficacy with good safety.

Objective:To investigate the influencing factors of falls in patients with chemotherapy-induced peripheral neuropathy for gynecological cancer, and establish a Nomogram model based on independent influencing factors.Methods:A total of 216 patients with peripheral neuropathy who received chemotherapy for gynecological cancer in The First Affiliated Hospital of Army Military Medical University of the People′s Liberation Army from February 2021 to April 2023 were retrospectively selected, and were divided into the modeling set and the validation set according to the ratio of 7∶3 using random number table method. According to the occurrence of falls in the modeling set, the patients were divided into the fall group and the non-fall group. Independent influencing factors were obtained through univariate analysis and multivariate Logistic regression analysis, and a prediction model was constructed based on the regression analysis. A Nomogram map was drawn using R language software. Receiver operating characteristic curve (ROC) and calibration curve were used to test the prediction efficiency, and the predictive benefits were evaluated by clinical decision curve.Results:Among the 216 patients, 151 were included in the modeling set and 65 in the validation set. Among the patients in the modeling set, 53 cases were in the fall group, aged (62.89 ± 8.58) years old, and 98 cases were in the non-fall group, aged (59.48 ± 8.12) years old. Chemotherapy cycle, Neuropathy Impairment Score-Lower Limbs, Barthel index, Home Falls and Accidents Screening Tool, regular exercise habits, diabetes and depression were all independent influencing factors for falls in patients with chemotherapy-induced peripheral neuropathy of gynecologic cancer ( OR values were 0.312-3.727, all P<0.05). The area under the curve (AUC) of the established Nomogram model was 0.873, with good discriminating ability. The mean absolute error (MAE) of calibration curve was 0.048, which fitted the ideal curve, indicating that the model has good calibration performance. The AUC of the validation set was 0.873 and the MAE of calibration curve was 0.073, indicating that the model has good external prediction efficiency. Conclusions:This Nomogram model can predict falls in patients with chemotherapy-induced peripheral neuropathy of gynecological cancer and provide evidence for clinical prevention of falls.
