Objective To evaluate the effect of different cold preservation time on liver regeneration after partial liver transplantation in rats,and study the role of IL-6/STAT3.Methods SD rats were divided into 3 groups:group Ⅰ underwent liver resection,group Ⅱ received partial liver transplantation after one-hour cold preservation and group Ⅲ received partial liver transplantation after 8-hour cold preservation.Radioimmunoassay was used to measure the levels of TNF-? and IL-6 in liver tissues.The protein expressions of PCNA and STAT3 were assessed by immunohistochemical staining in paraffin sections.The liver regeneration ratio and the expressions of the proliferative cell nuclear antigen(PCNA)and STAT3 were compared among three groups at 1,6,12,24,48,72 and 168 h after operation.Results The remnant liver in group Ⅰ and grafts in group Ⅱ grew rapidly;The regeneration ratio in group Ⅲ was significantly lower than that in group Ⅰ and group Ⅱ during postoperative day 2 to 3(P

[Objective] To evaluate the effect and safety of bee-stinging therapy in treating undifferentiated connective tissue disease (UCTD). [Methods] Forty cases of UCTD were treated with bee-stinging therapy (qd or qod) for two treatment course, each course lasting 15 times. The symptoms of morning stiffness (MS), joint pain (JP) and articular swelling (AS), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) and side effects were observed before and after treatment. [Results] After treatment, clinical symptoms and ESR and CRP were significantly improved (P

Objective To analyze the application value of enhanced depth imaging optical coherence tomography (EDI-OCT) in measuring the lamina cribrosa thickness(LCT) in patients with branch retinal vein occlusion (BRVO).Methods The clinical data of 65 patients with unilateral BRVO treated in our hospital from September 2014 to March 2016 were selected as the observation group.The single healthy eyes of 40 healthy individuals who received physical examination in the hospital during the same period were selected as the control group.The changes of retinal nerve fiber layer (RNFL) thickness,LCT,central corneal thickness,axial length,transverse diameter of optic disc,vertical diameter of optic disc,diopter and extent of visual field defect in the two groups were determined by EDI-OCT.Results There was no significant difference in the central corneal thickness,axial length,transverse diameter of optic disc,vertical diameter of optic disc and diopter between the two groups (all P ＞ 0.05).LCT of different regions of optic disc in the observation group were lower than those in the control group (all P ＜ 0.05).The range of visual field defects in the observation group was larger than that in the control group,and the RNFL thickness was lower than that in the control group (P ＜ 0.05).LCT was positively correlated with the thickness of whole RNFL in patients with BRVO,and was negatively correlated with the visual field defects (P ＜ 0.05).Conclusion EDI-OCT is an effective means for measuring LCT.LCT of patients with glaucoma BRVO is thinner than that of normal healthy people,and LCT is positively correlated with RNFL.thickness,and negatively correlated with visual field defects.

Objective To investigate the effects of Xuanfeitongfufang Decoction on expressions of MD-2, NF-κB protein and its mRNA in lung of the rats with acute lung injury caused by LPS. Methods Wistar rats were randomly divided into normal group, model group, dexamethasone group and Xuanfeitongfufang Decoction large-, medium-, small-dose group, each group had eight rats. The ALI rat model was established by LPS tail-intravenous injection (6 mg/kg). The rats in Xuanfeitongfufang Decoction groups were pretreated by Xuanfeitongfufang Decoction (15.12, 7.56, 3.78 g/kg) for 3 days before LPS induced ALI. The rats in dexamethasone group were pretreated by dexamethasone (5 mg/kg). MD-2, NF-κB protein and its mRNA were measured by immunohistochemistry and PCR. The histopathology of the lung injury was observed by light microscope. Results Compared with normal group, the expression of MD-2, NF-κB protein and its mRNA were obviously increased in model group (P<0.01). Compared with model group, the expression of MD-2, NF-κB protein and its mRNA were obviously decreased in Xuanfeitongfufang Decoction groups and dexamethasone group (P<0.01), and there was no obvious difference between Xuanfeitongfufang Decoction groups and dexamethasone group. Light microscope observation indicates that there were large areas of pulmonary hemorrhage and necrosis in model group. While in Xuanfeitongfufang Decoction group and dexamethasone group, the pathological manifestations were much more ameliorated than those of the model group. The lung bronchiale inflammation appeared occasionally, and the edema was lightly. Conclusion Xuanfeitongfufang Decoction can lessen the injury of lung tissue and has protective effects on rats with ALI, the mechanism is possibly related to the inhibition of the expressions of MD-2 and NF-κB protein and its mRNA in injured lung tissues.

Objective: To investigate the effectiveness of horticultural therapy on improving university students mental health problems and to provide evidence to support the application of horticultural therapy in the prevention and treatment of university students mental health. Methods: From March to May 2022,a before-and after paired design was used with a blank control group, mental health screening abnormalities were recruited from a comprehensive university in Hebei Province, including 57 in the intervention group and 21 in the control group, and the Symptom Checklist-90(SCL-90) score and hair cortisol were included as outcome indicators, which was measured by enzyme linked immunoassay Elisa double antibody sandwich method. Results: The total SCL-90 scores of the intervention group decreased ( t=4.28, P <0.01) and were significantly lower compared with the control group( t=-2.66, P <0.01), while no significant difference was observed in the control group( t=0.29, P >0.05), and the difference between the pre and post measures on each dimension of the SCL-90 was significantly lower in the intervention group (all P <0.01); the difference between the pre and post measures of hair cortisol contentration in the intervention group was statistically significant( Z= -2.75, P <0.05), and the hair cortiso contentration in pre measure group was lower than that of control group( Z=-3.48, P < 0.01 ). In contrast, the difference between pre and post measurements of hair cortisol in the control group was not significant( Z= -0.75 , P >0.05). Conclusion Horticultural therapy can improve the psychological symptoms of university students is suitable for psychological interventions in the university population and is beneficial to the health and well being of university students.

Purpose: To identify the predictors of infectious disease-specific health literacy (IDSHL), and establish an easy-to-apply nomogram to predict the IDSHL of older adults. Methods: This cross-sectional study included 380 older adults who completed the IDSHL, self-rated health, socio-demographic and other questionnaires. Logistic regression was used to identify the IDSHL predictors. Nomogram was used to construct a predictive model. Results: Up to 70.1% of older adults had limited IDSHL. Age, education, place of residence, self-rated health, and Internet access were the important influencing factors of IDSHL. The established nomogram model showed high accuracy (receiver operating characteristic curve: 0.848). Conclusions The IDSHL of Chinese older adults was significantly deficient. The constructed nomogram is an intuitive tool for IDSHL prediction that can not only contribute toward rapid screening of high-risk older adults with limited IDSHL but also provide guidance for healthcare providers to develop prevention strategies for infectious diseases.
