OBJECTIVES: To explore the bioactive components in Jiawei Xiaoyao Pills (JWXYP) and their mechanisms for alleviating depression-like behaviors. METHODS: The active compounds, key targets, and pathways of JWXYP were identified using TCMSP and TCMIP databases. Thirty-six SD rats were randomized equally into 6 groups including a control group and 5 chronic unpredictable mild stress (CUMS)-induced depression groups. After modeling, the 5 model groups were treated with daily gavage of normal saline, 1.8 mg/kg fluoxetine hydrochloride (positive control drug), or JWXYP at 1.44, 2.88, and 4.32 g/kg. The depression-like behaviors of the rats were evaluated using behavioral tests, and pathological changes in the liver and hippocampus were examined with HE staining. The biochemical indicators in the serum and brain tissues were detected using ELISA. Serum metabolomics analysis was performed to identify the differential metabolites using OPLS-DA, and gut microbiota changes were analyzed using 16S rDNA sequencing. RESULTS: Network pharmacology revealed that menthone and paeonol in JWXYP were capable of penetrating the blood-brain barrier to regulate inflammatory pathways and protect the nervous system. In the rat models subjected to CUMS, treatment with JWXYP significantly improved body weight loss, sucrose preference and open field activities, reduced liver inflammation, alleviated structural changes in the hippocampal neurons, decreased serum levels of TNF‑α, IL-1β, IL-6 and LBP, and increased 5-HT and VIP concentrations in the serum and brain tissue, and these effects were the most pronounced in the high-dose group. Metabolomics analysis showed changes in such metabolites as indole-3-acetamide and acetyl-L-carnitine in JWXYP-treated rats, involving the pathways for bile acid biosynthesis and amino acid metabolism. 16S rDNA analysis demonstrated increased gut microbiota diversity and increased abundance of Lactobacillus species in JWXYP-treated rats. CONCLUSIONS JWXYP alleviates depression-like symptoms in rats by regulating the neurotransmitters, inhibiting inflammation and oxidation, and modulating gut microbiota.

Objective: To understand the coincidence rate of adjustable and non adjustable desks and chairs in primary and secondary schools in Shanghai, so as to provide a reference for the effective management of desks and chairs in schools. Methods: Stratified random cluster sampling was applied to measure 1 091 sets of desks and chairs in 33 classrooms of 7 primary and secondary schools in 4 districts of Shanghai including Huangpu, Hongkou, Yangpu and Jiading districts. The height examination data of seated students in the same semester were also collected to evaluate the matching type of functional size of desks and chairs and students height according to Functional Sizes and Technical Requirements of Chairs and Tables for Educational Institutions. Results: The matching coincidence rate of desk and chair distribution in primary and secondary schools was 22.5%, and the matching coincidence rates of primary, middle and high schools were 11.7%, 27.1% and 40.9% respectively ( χ 2=83.23, P <0.01); the matching coincidence rate of adjustable desks and chairs (28.2%) was significantly higher than that of fixed (18.2%) ( χ 2=14.49, P <0.01). The type of distribution of desks and chairs that do not correspond to national standards, from elementary school to high school, showing a trend of high desks with high chairs, low desks with high chairs to high desks with low chairs. Conclusion The coincidence rate of desk and chair distribution in primary and secondary schools is low, and the adjustable desks and chairs has improved the problems to a certain extent, but has not significantly improved the coincidence rate. It is necessary to further explore the effective management mode in the use of adjustable desks and chairs and improve the current situation of the use of desks and chairs in schools.

Objective:To compare the efficacy and safety of insulin degludec and insulin glargine U100 in patients with type 2 diabetes mellitus.Methods:This study was a retrospective cohort study. The subjects were patients with type 2 diabetes mellitus who were hospitalized in 13 3A-level general hospitals in Shandong Province from September 2018 to December 2021. According to the type of basal insulin used, the patients were divided into insulin degludec group and insulin glargine U100 group. The basic information and laboratory test results in patients in the 2 groups were collected, the differences of fasting blood glucose level and incidence of hypoglycemia between the 2 groups were compared. The patients with complete blood glucose monitoring data in the 2 groups were selected and their blood glucose fluctuations were compared.Results:A total of 1 152 patients were entered in the study, including 552 patients in the insulin degludec group and 600 patients in the insulin glargine U100 group. The difference in the basic conditions in patients in the 2 groups was not statistically significant (all P>0.05). After treatment, the fasting blood glucose levels in patients in the 2 groups were lower than those before treatment, with statistically significant differences [10.2 (8.8, 12.5) mmol/L vs. 7.5 (6.6, 8.7) mmol/L, Z=-19.443, P<0.001; 10.0 (8.6, 11.7) mmol/L vs. 7.8 (6.6, 9.0) mmol/L, Z=-15.449, P<0.001], but the difference in fasting blood glucose levels between the 2 groups after treatment was not statistically significant ( Z=-1.427, P>0.05). The incidence of hypoglycemia in the insulin degludec group was lower than that in the insulin glargine U100 group [1.09% (6/552) vs. 2.83% (17/600), Z=4.481, P=0.032]. The intraday blood glucose standard deviation, maximum blood glucose fluctuation range, postprandial blood glucose fluctuation range, and average blood glucose fluctuation range in patients with complete blood glucose monitoring data in the insulin degludec group were significantly lower than those in the insulin glargine U100 group [(1.7±0.6) mmol/L vs. (2.4±1.0) mmol/L, (4.5±1.6) mmol/L vs. (6.7±2.9) mmol/L, (1.8±1.0) mmol/L vs. (3.3±1.2) mmol/L, (2.9±1.3) mmol/L vs. (4.6±2.1) mmol/L; all P<0.001]. Conclusion:The efficacy of insulin degludec in the treatment of type 2 diabetes mellitus is equivalent to that of insulin glargine U100, but the risk of hypoglycemia and blood glucose fluctuation is lower.

Objective: To study the effects of Phellodendron amurense on herpes simplex virus 1 (HSV-1) and cytokines, and to explore the mechanism of Phellodendron amurense inhibiting HSV-1 virus through multiple channels. Methods: Viruses were inoculated into medicine treated HeLa cells. The proliferation of virus was observed by fluorescence microscopy. The transcriptional levels of glycoprotein gD and functional protein US1 on the surface of virus envelope were detected by quantitative (q) PCR. After incubating HeLa cells for 24 h, qPCR was used to detect the expression of intrinsic immune factors such as IP-10, IL-12, IFN-gamma and transcription factor NF-kappa B (P65). The expression and nuclear location of NF-kappa B (P65) protein were detected by immunofluorescence. Results: Fluorescence showed that the proliferation of virus decreased significantly at 8 and 40 ng/ml (P<0.01), and the transcription levels of viral protein gD and US1 decreased (P<0.05). After incubation for 24 hours, the transcription levels of IP-10, IL-12 and IFN-gamma in HeLa cells increased significantly (P<0.01). The transcription level of transcription factor NF-kappa B (P65) also increased (P<0.05), and immunofluorescence showed that the nuclear penetration rate of p65 subunit of NF-kappa B (P65) in each group increased (P<0.05). Conclusions Phellodendron amurense extract can inhibit HSV-1 by inhibiting the transcription of viral functional protein and promoting the expression of cellular immune factors.

Objective To investigate the clinical value of gauze packing for haemodynamically unstable pelvic fracture.Methods Between January 2006 and January 2014,gauze packing was used to treat haemodynamically unstable pelvic fracture in 42 patients consisting of 23 males and the 19 females aged 34.2 years (range,18 to 54 years).AO classification of the fracture was type B1 in 9,B2 in 5,B3 in 3,C1 in 13,C2 in 4,and C3 in 8 patients.All the patients were diagnosed with hypovolemic shock upon admission with the systolic pressure of (75.4 ± 4.3) mmHg and heart rate of (126.5 ± 12.4) beats/ min.Injury severity score (ISS) was (38.7 ± 6.2)points.Anti-shock treatment,internal or external fixation of pelvic ring,and gauze packing were performed immediately to control the hemorrhage following pelvic fracture.Results Systolic pressure was (95.2 ± 4.6) mmHg and mean heart rate was declined to (85.4 ± 13.2)beats/min after pelvis volume control and gauze packing,with significant differences compared to these preoperatively (P ＜ 0.05).Red blood cell transfusion before internal or external fixation and gauze packing was (15.0 ± 2.4) units versus (8.3 ± 1.5) units within the first postoperative 24 hours (P ＜ 0.05).Twenty-four out of the 42 patients underwent temporary abdominal aorta occlusion.Six patients died postoperatively with the death rate of 14％.Mean time of removing the packing gauze was (51.4 ± 10.3) hours (range,24-168 hours).Conclusion Anti-shock treatment with concurrent gauze packing and pelvis volume control is effective to arrest the massive hemorrhage in hemodynamically unstable pelvic fracture.

BACKGROUNDPelvic fractures are uncommon in elderly patients and so are infrequently addressed in the literature. The purpose of this study was to investigate the management and outcome of pelvic fractures in elderly patients.

METHODSWe retrospectively reviewed the records of pelvic fractures in elderly patients (age ≥55 years) who were treated in our department from September 1997 to May 2010.

RESULTSA total of 40 elderly patients with pelvic fractures were identified. Their mean age was 65.8 years (range 55-87 years). About 68% (n = 27) were men. The average Injury Severity Score (ISS) was 17.8 (range 6-45). Twelve (30%) patients required blood transfusion (mean 10 units) during the first 24 hours. The fractures were most frequently due to falling from a standing position (48%). Almost half (48%) were grade I breaks. Associated injuries were present in 70% (n = 28) of patients, and 65% (n = 26) had medical co-morbidities. Altogether, 29 patients (73%) underwent non-surgical management of their pelvic fracture. The average hospital stay was 25 days. There were five in-hospital deaths and one death 10 months after discharge. High ISSs (>25) were associated with increased in-hospital mortality (P = 0.018). At the final assessment (mean follow-up 15 months), 52% of the surviving patients had experienced decreased self-sufficiency.

CONCLUSIONSPelvic fractures in elderly patients result in high morbidity and mortality rates. A high ISS (>25) can be used to identify a patient at high risk. We recommend aggressive resuscitation and intensive care for that patient. For patients with an unstable pelvic or displaced acetabular fracture (≥2 mm) who can endure surgery, open reduction and internal fixation can provide adequate fixation for early weight-bearing and restoration of the bone stock.
