ABSTRACT

The purpose of this study was to investigate the effects of post-traumatic stress disorder (PTSD) on electrophysiological characteristics of glutamatergic and GABAergic neurons in dorsal hippocampus (dHPC) and ventral hippocampus (vHPC) in mice, and to elucidate the mechanisms underlying the plasticity of hippocampal neurons and memory regulation after PTSD. Male C57Thy1-YFP/GAD67-GFP mice were randomly divided into PTSD group and control group. Unavoidable foot shock (FS) was applied to establish PTSD model. The spatial learning ability was explored by water maze test, and the changes in electrophysiological characteristics of glutamatergic and GABAergic neurons in dHPC and vHPC were examined using whole-cell recording method. The results showed that FS significantly reduced the movement speed, and enhanced the number and percentage of freezing. PTSD significantly prolonged the escape latency in localization avoidance training, shortened the swimming time in the original quadrant, extended the swimming time in the contralateral quadrant, and increased absolute refractory period, energy barrier and inter-spike interval of glutamatergic neurons in dHPC and GABAergic neurons in vHPC, while decreased absolute refractory period, energy barrier and inter-spike interval of GABAergic neurons in dHPC and glutamatergic neurons in vHPC. These results suggest that PTSD can damage spatial perception of mice, down-regulate the excitability of dHPC and up-regulate the excitability of vHPC, and the underlying mechanism may involve the regulation of spatial memory by the plasticity of neurons in dHPC and vHPC.

ABSTRACT

Ferroptosis is a novel iron-dependent mode of programmed cell death characterized by iron deposition and accumulation of lipid peroxidation. More and more studies have found that ferroptosis is closely related to the pathogenesis of type 2 diabetes mellitus (T2DM). The yin-fire theory is an important part of LI Gao's spleen-stomach theory, and it is believed that qi-fire imblance and yin-fire internal generation is the main pathogenesis of T2DM. Abnormal iron metabolism may be an important prerequisite for T2DM yin-fire internal generation, while oxidative stress is the specific manifestation of T2DM qi-fire imbalance. Reactive oxygen species (ROS) is the end product of qi-fire imbalance, and lipid peroxide is the pathological products of T2DM yin-fire internal generation. This study intends to explore the pathological mechanism of qi-fire imbalance and yin-fire internal generation from the perspectives of iron metabolism, oxidative stress and lipid peroxidation, enriching the modern connotation of yin-fire theory, and benefiting traditional Chinese medicine to target against ferroptosis, and prevent and treat T2DM precisely.

ABSTRACT

Objective:To introduce the concept and procedures of precise flap surgery in construction of knee defects and to report the preliminary clinical outcomes.Methods:The data of 16 patients with knee defects at 17 sides were retrospectively analyzed who had been treated under the guidance of the concept of precise flap surgery at Department of Orthopedic Surgery, The 920th Hospital of Joint Logistic Support Force of PLA from August 2014 to March 2022. There were 12 males and 4 females, aged 44(34, 54) years. The wounds were at the left side in 8 cases, at the right side in 7 ones and at bilateral sides in one, and their sizes ranged from 5 cm×3 cm to 15 cm×11 cm. The time from injury to surgery was 8.5(6.0, 13.0) days. Optimal repair protocols were chosen after the donor and recipient sites were evaluated according to the methods of precise flap surgery: a retrograde anterolateral thigh flap in 7 sides, a descending genicular artery perforator flap in 3 ones, a saphenous artery flap in 2 ones, and a superior genicular lateral artery perforator flap, a popliteal artery perforator flap, a medial sural perforator propeller flap, a peroneal artery perforator propeller flap, and a randomized flap in one, respectively. The flap sizes ranged from 10 cm×6 cm to 15 cm×15 cm. The outcomes and complications of skin flap repair, and functional recovery of the affected limb were recorded.Results:All the flaps at 17 sides survived after surgery; 3 cases developed distal edge necrosis which responded to dressing change. The follow-ups for the 16 patients were 14.5(10.0, 28.0) months. All the flaps presented with good color, texture and contour. Flap bulking, local osteomyelitis, and scar ulcer was found in one case respectively. According to the revascularization assessments in the digital replantation criteria by Hand Surgery Society, Chinese Medical Association, all the flaps at 17 sides were excellent. Accoding to the knee functional evaluation of Hospital for Special Surgery (HSS) at the last follow-up, the 17 affected limbs scored 86(80,91) points, yielding 9 excellent, 7 good and 1 fair sides.Conclusion:Although the defects and donor sites around the knee vary greatly, precise flap surgery may lead to effective control of the variations, choice of an optimal reconstruction protocol, and precise wound repair.

ABSTRACT

ObjectiveTo compare the therapeutic effects of oral Chinese medicines (including Chinese patent medicines) on coronary artery disease (CAD) by the Bayesian network Meta-analysis. MethodThe randomized controlled trials of treating CAD with oral Chinese medicines were retrieved from the China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, PubMed, Web of Science, Embase, and Cochrane Library from the inception to December 1, 2022. The Cochrane risk of bias assessment tool was used to evaluate the quality of the included articles. The direct meta-analysis was performed to compare the performance of oral Chinese medicines alone and in combination with Western medicine in the treatment of CAD in terms of intima-media thickness (IMT), vascular endothelial function, plaque score, hypersensitive C-reactive protein (hs-CRP), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and total response rate. Furthermore, the Bayesian network Meta-analysis was performed to compare the therapeutic effects of different Chinese medicines. ResultA total of 41 articles were included. The direct meta-analysis results showed that Chinese medicines combined with Western medicine outperformed Western medicine alone in recovering all the indicators of CAD. The Bayesian network meta-analysis yielded the following results. In terms of the total response rate, modified Huangqi Guizhi Wuwutang and Sanqi Huayu pills had obvious advantages over other Chinese medicines. In terms of IMT and plaque score, Xiaoban Huazhuo decoction, Yiqi Tongluo formula, Ruangan Jiangzhi capsules, and Guanxin Shutong capsules had obvious advantages over other Chinese medicines. In terms of blood lipid indicators, Shenqi Roumai mixture, Ruangan Jiangzhi capsules, Xiaoban Huazhuo decoction, Qiwei Sanxiong decoction, and Sanqi Huayu pills were superior to other Chinese medicines. The Chinese medicines above mainly had the functions of activating blood, resolving stasis, resolving phlegm, and dredging vessels. ConclusionThe combination of oral Chinese medicines and Western medicine is effective in treating CAD. Clinicians can use the drugs targeting abnormal indicators according to the results of this Bayesian network meta-analysis combined with the actual situation of patients to achieve better therapeutic effects.

ABSTRACT

Objective:To analyze the endoscopic characteristics of early gastric cancer and precancerous lesions after Helicobacter pylori ( H. pylori) eradication. Methods:From May 2019 to June 2022, at Shanghai Sixth People′s Hospital affiliated to Shanghai Jiaotong University School of Medicine, the medical data of patients diagnosed with differentiated early gastric cancer and precancerous lesions were collected. A total of 93 patients with early gastric cancer and precancerous lesions who had previous history of H. pylori infection and had undergone standardized eradication treatment were selected, and their endoscopic characteristics were retrospectively analyzed. Independent sample t-test, chi-square test, and Fisher′s exact test were used for statistical analysis. Results:Among 93 patients with early gastric cancer and precancerous lesions after H. pylori eradication, there were 56 males and 37 females, with an average age of (66.9±8.2) years old. The time after H. pylori eradication was 3.4 years (range 1.0 to 7.0 years). A total of 109 early gastric cancer and precancerous lesions were found, including 79 patients with single lesion and 14 patients with multiple lesions (30 lesions). There were 60 cases with 73 lesions in the early gastric cancer group and 33 cases with 36 lesions in the precancerous group. Among 93 patients, 89 cases (95.7%) were diagnosed with atrophy level above C-2 according to Kimura-Takemoto classification under endoscopy. The long diameter of 109 lesions was (1.38±0.70) cm and the short diameter was (1.04±0.53) cm. A total of 80 lesions (73.4%) were located in the lower 1/3 part of the stomach, and 53 lesions (48.6%) were located in the lesser curvature. A total of 106 lesions (97.2%) were superficial type (0-Ⅱ) under the endoscopy. The long diameter and short diameter in the early gastric cancer group after H. pylori eradication were both greater than those in the precancerous lesion group ((1.54±0.78) cm vs. (1.06±0.35) cm, (1.16±0.58) cm vs. (0.78±0.33) cm), and the differences were statistically significant ( t=3.53 and 3.73, both P<0.001). There was statistically significant difference in the morphological types between early gastric cancer group after H. pylori eradication and precancerous lesion group ( χ2=11.01, P=0.012). The main morphological type of early gastric cancer after H. pylori eradication was superficial depression type (0-Ⅱc), accounting for 45.2% (33/73), while the precancerous lesions were mainly superficial protruded and flat type, both accounting for 38.9% (14/36). Conclusions:After H. pylori eradication, the endoscopic atrophy range of early gastric cancer and precancerous lesions is mostly above C-2. And the lesions are mostly located in the middle and lower 1/3 part of the stomach, long diameter of lesions <20 mm. The main morphological type is superficial type, especially superficial depression type.

ABSTRACT

ObjectiveTo determine the mechanism of Yitangkang in correcting excessive apoptosis of skeletal muscle cells to improve insulin resistance (IR) by inhibiting the advanced glycation end product (AGE)/receptor for the advanced glycation end product (RAGE) signaling pathway. Method① In vitro experiments. Yitangkang-medicated serum was prepared. C2C12 cells were divided into a blank group, a model group, high-, medium-, and low-dose Yitangkang-medicated serum groups (40, 20, and 10 g·kg-1), and a RAGE inhibitor group. The IR model was induced by palmitic acid in C2C12 cells except for those in the blank group. After the corresponding intervention methods were conducted,the cell viability and glucose consumption level of each group were determined. In addition,the apoptosis rate was determined using flow cytometry. The mRNA and protein expression levels of the important apoptotic proteins [B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), p53, cysteinyl aspartate-specific protease-3 (Caspase-3), and cysteinyl aspartate-specific protease-9 (Caspase-9)] were determined using Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot. ② In vivo experiments. Ninety-six eligible Wistar rats were divided into a blank group, a model group, high-,medium-,and low-dose Yitangkang groups (40, 20, and 10 g·kg-1), and a western medicine group (pioglitazone hydrochloride,1.35 mg·kg-1). The IR model was induced using high-glucose and high-fat feed for diabetes combined with intraperitoneal injection of low-dose streptozotocin (STZ) in animals and verified by the hyperinsulinemic-euglycemic clamp (HEC) test. After the model was determined successfully, the rats in each group were given intragastric administration of drugs as required. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay was performed to determine the number of positive apoptotic cells in the skeletal muscle tissues of rats in each group,while Real-time polymerase chain reaction(Real-time PCR) and Western blot were performed to determine the mRNA and protein expression levels of the important apoptotic proteins Bcl-2, Bax, p53, Caspase-3, and Caspase-9. Result① In vitro experiments. compared with the blank group, the model groups showed increased apoptosis rate of C2C12 cells and decreased cell viability and glucose consumption (P<0.01). Compared with the model group, the Yitangkang-medicated serum groups and the RAGE inhibitor group showed decreased apoptosis rate of C2C12 cells and increased cell viability and glucose consumption (P<0.01). Compared with the blank group, the model group showed decreased expression levels of Bcl-2 mRNA and protein in C2C12 cells and increased mRNA and protein expression levels of Bax, p53, Caspase-3, and Caspase-9 (P<0.01). Compared with the model group, the Yitangkang-medicated serum groups and the RAGE inhibitor group showed increased expression levels of Bcl-2 mRNA and protein in C2C12 cells (P<0.01) and decreased mRNA and protein expression levels of Bax, p53, Caspase-3, and Caspase-9 (P<0.05, P<0.01). ② In vivo experiments. The number of positive apoptotic cells in the skeletal muscle tissues of rats in the model group significantly increased as compared with that in the blank group (P<0.01). The number of positive apoptotic cells in the skeletal muscle tissues of rats in the Yitangkang groups and the western medicine group decreased as compared with that in the model group (P<0.01). Compared with the blank group, the model group showed decreased expression levels of Bcl-2 mRNA and protein in skeletal muscle tissues of rats and increased mRNA and protein expression levels of Bax, p53, Caspase-3, and Caspase-9 (P<0.01). Compared with the model group, the Yitangkang groups and the western medicine group showed increased expression levels of Bcl-2 mRNA and protein in skeletal muscle tissues of rats (P<0.01) and decreased mRNA and protein expression levels of Bax, p53, Caspase-3, and Caspase-9 (P<0.05, P<0.01). The medium-dose Yitangkang showed a similar effect as RAGE inhibitor, and the effect was equivalent to that of pioglitazone hydrochloride. ConclusionYitangkang can inhibit skeletal muscle cell apoptosis by inhibiting the AGE/RAGE signaling pathway.

ABSTRACT

Objective@#To explore the patterns of health risk behaviors among secondary school students in Shanghai, so as to provide a basis for implementing targeted interventions.@*Methods@#From May to June 2021, 21 junior high schools, regular high schools and secondary vocational schools were selected from Shanghai, and the occurrence of dangerous health behaviors of 6 092 students were investigated in the form of self-filled questionnaires. The clustering analysis of the sample was performed by Ward s departure and peace method.@*Results@#Three types of clustering characteristics were found in this study: being bullied, depression (64.9%), loneliness (48.2%), and insomnia (42.4%) in the high-risk group (1 004, 16.5%); excessive video games (53.1%) and sugary drinks (89.3%) and fried food intake (79.0%) in the medium-risk group (1 585, 26.0%); the low-risk group (3 503, 57.5%) was characterized by extremely low alcohol consumption (0) and smoking (0.4%). The reporting rate on sugary beverage intake, fried food intake, physical activity, malicious teased, solicited, isolated/intentionally excluded, outside the group activities, threatened, kicked/hit/pushed/locked in house, smoking, unhealthy weight loss, playing video game overtime were statistically significant among the three groups ( χ 2=36.74, 41.85, 30.07, 652.68, 334.40, 669.89, 358.84, 233.12, 101.46, 88.45, 230.15, P <0.01) .The difference in reporting rates of loneliness, depression, insomnia and drinking were significant among the three groups (Fisher s test, P <0.01). The majority of junior high school students, general high school students and girls in the high-risk group; boys, general high school students and junior high school students in the excessive video game and unhealthy diet group.@*Conclusion@#There are clusters of health-related risk behaviors among secondary school students in Shanghai, focusing on two major aspects: poor lifestyle and mental health. Targeted interventions should be implemented according to the characteristics of health-related risk behaviors clustering to enhance the intervention effect.

ABSTRACT

To provide proof of the evidence-based medicine and decision-making information for the clinical decision of functional gastrointestinal disorders(FGIDs), this study evaluated and compared the efficacy, safety, and economy of four oral Chinese patent medicines(CPMs) in the treatment of FGIDs using the method of rapid health technology assessment. The literature was systematically retrieved from CNKI, Wanfang, VIP, SinoMed, EMbase, PubMed, Cochrane Library and ClinicalTrials.gov from the establishment of the databases to May 1, 2022. Two evaluators screened out the literature, extracted data, evaluated the quality of the literature, and descriptively analyzed the results according to the prepared standard. Eventually, 16 studies were included, all of which was rando-mized controlled trial(RCT). The results showed that Renshen Jianpi Tablets, Renshen Jianpi Pills, Shenling Baizhu Granules, and Buzhong Yiqi Granules all had certain effects on the treatment of FGIDs. Renshen Jianpi Tablets treated FGIDs and persistent diarrhea. Shenling Baizhu Granules treated diarrhea with irritable bowel syndrome and FGIDs. Buzhong Yiqi Granules treated diarrhea with irritable bowel syndrome, FGIDs, and chronic diarrhea in children. Renshen Jianpi Pills treated chronic diarrhea. The four oral CPMs all have certain effects on the treatment of FGIDs and have specific advantages for specific patients. Compared with other CPMs, Renshen Jianpi Tablets have higher clinical universality. However, there are problems such as insufficient clinical research evidence, generally low quality of evidence, lack of comparative analysis among medicines, and lack of academic evaluation. More high-quality clinical research and the economic research should be carried out in the future, so as to provide more evidence for the evaluation of the four CPMs.

ABSTRACT

In this study, rapid evaporative ionization mass spectrometry(REIMS) fingerprints of 388 samples of roots of Pulsatilla chinensis(PC) and its common counterfeits, roots of P. cernua and roots of Anemone tomentosa were analyzed based on REIMS combined with machine learning. The samples were determined by REIMS through dry burning, and the REIMS data underwent cluster analysis, similarity analysis(SA), and principal component analysis(PCA). After dimensionality reduction by PCA, the data were analyzed by similarity analysis and self-organizating map(SOM), followed by modeling. The results indicated that the REIMS fingerprints of the samples showed the characteristics of variety differences and the SOM model could accurately distinguish PC, P. cernua, and A. tomentosa. REIMS combined with machine learning algorithm has a broad application prospect in the field of traditional Chinese medicine.

ABSTRACT

ObjectiveTo analyze the characteristics of hospitalized unintentional injuries and to provide evidence for formulating injury prevention and control strategies. MethodsDescriptive analysis was conducted on injury information of unintentional injury cases reported from 22 monitoring hospitals during 2017 to 2020 by injury surveillance system. The composition ratio index was used to analyze and explore the distribution(population, time and place)of injuries related to different causes. The disease burden was described by the length of hospital stay and hospitalization cost. ResultsA total of 32 716 hospitalized unintentional injury cases were reported from 22 monitoring hospitals. The male to female ratio was 1.18∶1. The majority of males were aged 15‒64 years and the majority of females were aged over 45 years. The top three causes of injuries were falls, traffic-related and blunt injury. Injuries occurred more frequently in July and August. 42.81% of the cases occurred at home. Fracture cases accounted for 75.79%. The median length of hospital stay was 10 days and the median cost was 15 431.50 yuan. The share of both falls and non-motor vehicle accidents increased year by year. ConclusionFalls among elderly people and road traffic injuries are the main causes of hospitalized unintentional injuries, and sharp or blunt instrument injuries are more severe in the male workforce. Considering high direct and indirect economic losses from injuries, steps should to be taken to improve injury surveillance system and to implement injury prevention and control strategies targeted on key groups and key injuries.

ABSTRACT

Peptides are increasingly important resources for biological and therapeutic development, however, their intrinsic susceptibility to proteolytic degradation represents a big hurdle. As a natural agonist for GLP-1R, glucagon-like peptide 1 (GLP-1) is of significant clinical interest for the treatment of type-2 diabetes mellitus, but its in vivo instability and short half-life have largely prevented its therapeutic application. Here, we describe the rational design of a series of α/sulfono-γ-AA peptide hybrid analogues of GLP-1 as the GLP-1R agonists. Certain GLP-1 hybrid analogues exhibited enhanced stability (t 1/2 > 14 days) compared to t 1/2 (<1 day) of GLP-1 in the blood plasma and in vivo. These newly developed peptide hybrids may be viable alternative of semaglutide for type-2 diabetes treatment. Additionally, our findings suggest that sulfono-γ-AA residues could be adopted to substitute canonical amino acids residues to improve the pharmacological activity of peptide-based drugs.

ABSTRACT

This cross-sectional study aimed to investigate the quality of care of diabetes in Shanghai, China. A total of 173 235 patients with type 2 diabetes in 2017 were included in the analysis. Profiles of risk factors and intermediate outcomes were determined. The patients had a mean age of 66.43 ± 8.12 (standard deviation (SD)) years and a mean diabetes duration of 7.95 ± 5.53 (SD) years. The percentage of patients who achieved the target level for HbA1c (< 7.0%) was 48.6%. Patients who achieved the target levels for blood pressure (BP) < 130/80 mmHg and low-density lipoprotein-cholesterol (LDL-c) < 2.6 mmol/L reached 17.5% and 34.0%, respectively. A total of 3.8% achieved all three target levels, and the value increased to 6.8% with an adaptation of the BP target level (< 140/90 mmHg) for those over 65 years. Multivariable analysis identified the factors associated with a great likelihood of achieving all three target levels: male, young age, short diabetes duration, low body mass index, macrovascular complications, no microvascular complications, prescribed with lipid-lowering medication, and no prescription of antihypertensive medication. In conclusion, nearly 50% and one-third of the patients with diabetes met the target levels for HbA1c and LDL-c, respectively, with a low percentage achieving the BP target level. The percentage of patients who achieved all three target levels needs significant improvement.

ABSTRACT

Objective: To compare the clinical efficacy and quality of life between uncut Roux-en-Y and Billroth II with Braun anastomosis in laparoscopic distal gastrectomy for gastric cancer patients. Methods: A retrospective cohort study was performed. Inclusion criteria: (1) 18 to 75 years old; (2) gastric cancer proved by preoperative gastroscopy, CT and pathological results and tumor was suitable for D2 radical distal gastrectomy; (3) postoperative pathological diagnosis stage was T1-4aN0-3M0 (according to the AJCC-7th TNM tumor stage), and the margin was negative; (4) Eastern Cooperative Oncology Group (ECOG) physical status score <2 points, and American Association of Anesthesiologists (ASA) grade 1 to 3; (5) no mental illness; (6) able to answer questionnaires independently; (7) patients agreed to undergo laparoscopic distal gastrectomy and signed an informed consent. Exclusion criteria: (1) patients with severe chronic diseases and American Association of Anesthesiologists (ASA) grade >3; (2) patients with other malignant tumors; (3) patients suffered from serious mental diseases; (4) patients received neoadjuvant chemotherapy or immunotherapy. According to the above criteria, clinical data of 200 patients who underwent laparoscopic distal gastrectomy at the Department of General Surgery of the First Affiliated Hospital of Army Medical University from January 2016 to December 2019 were collected. Of the 200 patients, 108 underwent uncut Roux-en-Y anastomosis and 92 underwent Billroth II with Braun anastomosis. The general data, intraoperative and postoperative conditions, complications, and endoscopic evaluation 1 year after the surgery were compared. Besides, the quality of life of two groups was also compared using the Chinese version of the European Organization For Research and Treatment of Cancer (EORTC) quality of life questionnaire-Core 30 (QLQ-C30) and quality of life questionnaire-stomach 22 (QLQ-STO22). Results: There were no significant differences in baseline data between the two groups (all P>0.05). All the 200 patients successfully underwent laparoscopic distal gastrectomy without intraoperative complications, conversion to open surgery or perioperative death. There were no significant differences between two groups in operative time, intraoperative blood loss, postoperative complications, time to flatus, time to removal of gastric tube, time to liquid diet, time to removal of drainage tube or length of postoperative hospital stay (all P>0.05). Endoscopic evaluation was conducted 1 year after surgery. Compared to Billroth II with Braun group, the uncut Roux-en-Y group had a significantly lower incidences of gastric stasis [19.8% (17/86) vs. 37.0% (27/73), χ(2)=11.199, P=0.024], gastritis [11.6% (10/86) vs. 34.2% (25/73), χ(2)=20.892, P<0.001] and bile reflux [1.2% (1/86) vs. 28.8% (21/73), χ(2)=25.237, P<0.001], and the differences were statistically significant. The EORTC questionnaire was performed 1 year after surgery, there were no significant differences in the scores of QLQ-C30 scale between the two groups (all P>0.05), while the scores of QLQ-STO22 showed that, compared to the Billroth II with Braun group, the uncut Roux-en-Y group had a lower pain score (median: 8.3 vs. 16.7, Z=-2.342, P=0.019) and reflux score (median: 0 vs 5.6, Z=-2.284, P=0.022), and the differences were statistically significant (all P<0.05), indicating milder symptoms. Conclusion: The uncut Roux-en-Y anastomosis is safe and reliable in laparoscopic distal gastrectomy, which can reduce the incidences of gastric stasis, gastritis and bile reflux, and improve the quality of life of patients after surgery.
