ObjectiveTo explore the cumulative incidence of diabetes mellitus and its influencing factors among the diabetes mellitus high-risk groups in Minhang District of Shanghai, and to provide a basis for the development of community-based diabetes mellitus early prevention and treatment strategies in Shanghai. MethodsThe data of this study were collected from the screening project of diabetes mellitus high-risk groups in Minhang District of Shanghai, which was carried out from 2016‒2017. A total of 12 278 people were screened, of which 10 442 were at high risk based on the results of blood glucose diagnosis except those with diabetes. People diagnosed with abnormal fasting blood glucose, impaired fasting blood glucose and abnormal glucose tolerance were classified into the abnormal blood glucose group, and those with normal fasting blood glucose were classified into the normal blood glucose group. In 2023, the cumulative incidence of diabetes mellitus in the 2 groups was followed up, furthermore, the influencing factors of diabetes mellitus were analyzed. ResultsA total of 8 774 cases within the high-risk groups were followed up in 2023, of which 808 cases progressed to diabetes. Of the 8 774 cases, the cumulative incidence of diabetes mellitus in the abnormal blood glucose group (n=2 163) was 16.37% (354/2 163), and that in the normal blood glucose group (n=6 611) was 6.87% (454/6 611), and the difference in cumulative incidence of diabetes mellitus between the 2 groups was statistically significant (χ²=175.88, P<0.001). A history of impaired glucose regulation (OR=2.828, 95%CI: 2.177‒3.675), family history of type 2 diabetes (OR=1.294, 95%CI: 1.047‒1.600), hypertension (OR=1.268, 95%CI: 1.083‒1.485), dyslipidemia (OR=1.205, 95%CI: 1.003‒1.448), overweight/obesity (OR=1.526, 95%CI: 1.300‒1.792) were positively correlated with the cumulative incidence of type 2 diabetes, while female gender (OR=0.785, 95%CI: 0.675‒0.914) and sedentary lifestyle (OR=0.506, 95%CI: 0.374‒0.685) were negatively correlated with the cumulative incidence of type 2 diabetes. ConclusionBlood glucose monitoring should be strengthened in diabetes mellitus high-risk groups with an impaired glucose regulation history, a family history of type 2 diabetes, hypertension, and dyslipidemia, so as to achieve early detection of diabetes. Timely intervention measures should be taken for high-risk population with unhealthy lifestyle or overweight/obesity.

Objective To investigate the expression of intercellular adhesion molecule 1(ICAM-1)in patients with diabetic foot ulcer(DFU)and its correlation with inflammatory cytokines.Methods A total of 152 patients with DFU(DFU group)and 133 patients with type 2 diabetes mellitus(T2DM group)admitted to our hospital from January 2021 to December 2022 were selected as the study group.120 healthy people matched in age and sex were set as the control group(NC group).Pearson correlation analysis was applied to analyze the correlation between serum ICAM-1 and wagner grade in DFU patients.Results HbA1c,TG,ICAM-1,C-RP,TNF-α,IL-6,IL-18,IL-1β in NC,T2DM and DFU groups gradually increased,but HDL-C gradually decreased(P＜0.05).Pearson correlation analysis showed that serum ICAM-1 was positively associated with C-RP and TNF-α,IL-6,IL-18,IL-1β and wagner grading in DFU patients(P＜0.01).Logistic regression analysis showed that ICAM-1,C-RP,HbA1c and IL-18 were the influencing factors of DFU.Conclusion High levels of serum ICAM-1 in DFU patients are closely related to inflammatory factors and Wagner grading,which helps to identify the severity of the condition.

Objective: To explore the effect of perioperative chemotherapy on the prognosis of gastric cancer patients under real-world condition. Methods: A retrospective cohort study was carried out. Real world data of gastric cancer patients receiving perioperative chemotherapy and surgery + adjuvant chemotherapy in 33 domestic hospitals from January 1, 2014 to January 31, 2016 were collected. Inclusion criteria: (1) gastric adenocarcinoma was confirmed by histopathology, and clinical stage was cT2-4aN0-3M0 (AJCC 8th edition); (2) D2 radical gastric cancer surgery was performed; (3) at least one cycle of neoadjuvant chemotherapy (NAC) was completed; (4) at least 4 cycles of adjuvant chemotherapy (AC) [SOX (S-1+oxaliplatin) or CapeOX (capecitabine + oxaliplatin)] were completed. Exclusion criteria: (1) complicated with other malignant tumors; (2) radiotherapy received; (3) patients with incomplete data. The enrolled patients who received neoadjuvant chemotherapy and adjuvant chemotherapy were included in the perioperative chemotherapy group, and those who received only postoperative adjuvant chemotherapy were included in the surgery + adjuvant chemotherapy group. Propensity score matching (PSM) method was used to control selection bias. The primary outcome were overall survival (OS) and progression-free survival (PFS) after PSM. OS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the last effective follow-up or death. PFS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the first imaging diagnosis of tumor progression or death. The Kaplan-Meier method was used to estimate the survival rate, and the Cox proportional hazards model was used to evaluate the independent effect of perioperative chemo therapy on OS and PFS. Results: 2 045 cases were included, including 1 293 cases in the surgery+adjuvant chemotherapy group and 752 cases in the perioperative chemotherapy group. After PSM, 492 pairs were included in the analysis. There were no statistically significant differences in gender, age, body mass index, tumor stage before treatment, and tumor location between the two groups (all P>0.05). Compared with the surgery + adjuvant chemotherapy group, patients in the perioperative chemotherapy group had higher proportion of total gastrectomy (χ(2)=40.526, P<0.001), smaller maximum tumor diameter (t=3.969, P<0.001), less number of metastatic lymph nodes (t=1.343, P<0.001), lower ratio of vessel invasion (χ(2)=11.897, P=0.001) and nerve invasion (χ(2)=12.338, P<0.001). In the perioperative chemotherapy group and surgery + adjuvant chemotherapy group, 24 cases (4.9%) and 17 cases (3.4%) developed postoperative complications, respectively, and no significant difference was found between two groups (χ(2)=0.815, P=0.367). The median OS of the perioperative chemotherapy group was longer than that of the surgery + adjuvant chemotherapy group (65 months vs. 45 months, HR: 0.74, 95% CI: 0.62-0.89, P=0.001); the median PFS of the perioperative chemotherapy group was also longer than that of the surgery+adjuvant chemotherapy group (56 months vs. 36 months, HR=0.72, 95% CI:0.61-0.85, P<0.001). The forest plot results of subgroup analysis showed that both men and women could benefit from perioperative chemotherapy (all P<0.05); patients over 45 years of age (P<0.05) and with normal body mass (P<0.01) could benefit significantly; patients with cTNM stage II and III presented a trend of benefit or could benefit significantly (P<0.05); patients with signet ring cell carcinoma benefited little (P>0.05); tumors in the gastric body and gastric antrum benefited more significantly (P<0.05). Conclusion: Perioperative chemotherapy can improve the prognosis of gastric cancer patients.

OBJECTIVE: Herbal medicine is an important therapeutic option for benign prostatic hyperplasia (BPH), a common disease in older men that can seriously affect their quality of life. Currently, it is crucial to develop agents with strong efficacy and few side effects. Herein we investigated the effects of the extract of Rauwolfia vomitoria, a shrub grown in West Africa, on BPH. METHODS: Rats with testosterone-induced BPH were treated with R. vomitoria. Prostates were histologically analyzed by Hematoxylin and eosin staining. Proliferation index and the expression levels of androgen receptor and its associated proteins were quantified through immunohistochemistry and immunoblotting. Androgen receptor target genes were examined by quantitative real-time polymerase chain reaction. The sperm count and body weight of rats were also measured. RESULTS: The oral administration of R. vomitoria extract significantly reduced the prostate weight and prostate weight index in BPH rats, supported by the decreased thickness of the prostate epithelial layer and increased lumen size. Similar effects were observed in the BPH rats treated with the reference drug, finasteride. R. vomitoria extract significantly reduced the testosterone-induced proliferation markers, including proliferating cell nuclear antigen and cyclin D1, in the prostate glands of BPH rats; it also reduced levels of androgen receptor, its associated protein steroid 5α-reductase 1 and its downstream target genes (FK506-binding protein 5 and matrix metalloproteinase 2). Notably, compared with the finasteride group, R. vomitoria extract did not significantly reduce sperm count. CONCLUSION R. vomitoria suppresses testosterone-induced BPH development. Due to its milder side effects, R. vomitoria could be a promising therapeutic agent for BPH.

Inflammatory bowel diseases (IBD) are non-specific inflammatory diseases of unknown cause, mainly including ulcerative colitis and Crohn’s disease. IBDs have some similarities to peptic ulcer diseases (PUD) in clinical manifestations, histopathological changes and treatment strategies, and therefore pepsin might have a similar effect on both PUD and IBD. Recent studies show that “self-digestion” induced by digestive enzymes, especially trypsin, may play an important role in the development and progression of IBD. This article focuses on the role of mucosal barrier injury induced by trypsin and self-digestion in the formation of digestive ulcer in IBD.

Inflammatory bowel disease(IBD) is a chronic non-specific inflammatory disorder that commonly affects gastrointestinal tract. The cause is not clear. Previous studies have shown that IBD patients often suffer from anxiety and depression, which may be associated with impaired brain structure and function and changes in gut microbiome. Based on these findings, many researches indicate brain-gut-microbiome axis may play an important role in the occurrence and development of IBD. Blood oxygenation level dependent functional magnetic resonance (BOLD-fMRI) can detect brain function area with special response accurately and objectively, which helps to investigate the changes of brain function and its pathogenesis in IBD patients. This article reviews the current status and future prospects in IBD brain function changes based on the brain-gut-microbiome axis.

BackgroundThe increasing frequency of explosive injuries has increased interest in blast-induced traumatic brain injury (bTBI). Various shock tube models have been used to study bTBI. Mild-to-moderate explosions are often overlooked because of the slow onset or mildness of the symptoms. However, heavy gas cylinders and large volume chambers in the model may increase the complexity and danger. This study sought to design a modified model to explore the effect of moderate explosion on brain injury in mice.

MethodsPathology scoring system (PSS) was used to distinguish the graded intensity by the modified model. A total of 160 mice were randomly divided into control, sham, and bTBI groups with different time points. The clinical features, imaging features, neurobehavior, and neuropathology were detected after moderate explosion. One-way analysis of variance followed by Fisher's least significant difference posttest or Dunnett's t 3-test was performed for data analyses.

ResultsPSS of mild, moderate, and severe explosion was 13.4 ± 2.2, 32.6 ± 2.7 (t = 13.92, P < 0.001; vs. mild group), and 56.6 ± 2.8 (t = 31.37, P < 0.001; vs. mild group), respectively. After moderate explosion, mice showed varied symptoms of malaise, anorexia, incontinence, apnea, or seizure. After bTBI, brain edema reached the highest peak at day 3 (82.5% ± 2.1% vs. 73.8% ± 0.6%, t = 7.76, P < 0.001), while the most serious neurological outcomes occurred at day 1 (Y-maze: 8.25 ± 2.36 vs. 20.00 ± 4.55, t = -4.59, P = 0.048; 29.58% ± 2.84% vs. 49.09% ± 11.63%, t = -3.08, P = 0.008; neurologic severity score: 2.50 ± 0.58 vs. 0.00 ± 0.00, t = 8.65, P = 0.016). We also found that apoptotic neurons (52.76% ± 1.99% vs. 1.30% ± 0.11%, t = 57.20, P < 0.001) and gliosis (2.98 ± 0.24 vs. 1.00 ± 0.00, t = 14.42, P = 0.021) in the frontal were significantly higher at day 3 post-bTBI than sham bTBI.

ConclusionsWe provide a reliable, reproducible bTBI model in mice that can produce a graded explosive waveform similar to the free-field shock wave in a controlled laboratory environment. Moderate explosion can trigger mild-to-moderate blast damage of the brain.

Objective To explore the feasibility of needle-embedding therapy in the treatment of chronic myocardial ischemia using a miniature pig model established by placement of an Ameroid constrictor at the left anterior descending branch (LAD) of coronary artery in Bama miniature pigs during surgery. Methods The miniature pig model of chronic myocardial ischemia was established by placement of an Ameroid constrictor at the left anterior descending branch of the left coronary artery in Bama miniature pigs. The pig models were randomly divided into the treatment group (the"Neiguan " group) and the control group (the "Zusanli " group), and were treated with needle- embedding electroacupuncture at the"Neiguan" (PC6) and "Zusanli" (ST36) acupoints, respectively. Myocardial samples were taken at 6 weeks after surgery for light and electron microscopic examinations. Results Gross pathology showed that ischemic area in the myocardium appeared in both experimental groups. The ischemic area in the "Zusanli "group was larger than that of the"Neiguan"group. Histopathology showed that the acupuncture treatment at the"Neiguan"acupoint reduced the ischemic injury in the pig myocardial tissues. Ultrastructural observation of the myocardium showed mitochondrial vacuolization in cardiomyocytes and myocardial fibrosis in both groups. Conclusions Acupuncture therapy at the"Neiguan"acupoint of pericardial channel may exert protective effect on the myocardial ischemia by reducing the ischemia-injury of cardiomyocytes, but can not inhibit the already existed ischemia-induced cardiomyocytic injuries. Our findings suggest that the establishment of miniature pig model of chronic myocardial ischemia by surgically placing an Ameroid constrictor on the left anterior descending branch of left coronary artery and the needle-embedding in acupoints is feasible for the treatment of chronic myocardial ischemia in this pig model.

Colorectal cancer is a malignant disease of digestive system, with increasing morbidity. As a risk factor of colorectal cancer, high fat diet changes the secretory form of hepatic bile acids and stimulates its secretion. As a result, it increases the concentration of bile acids in the large intestine. Deoxycholic acid promotes the initiation and progression of colorectal cancer through affecting various intracellular signals, modulating expression of multiple genes and influencing the balance of the gut microbiota. The article reviewes the mechanisms of deoxycholic acid to promote the initiation and progression of colorectal cancer.

OBJECTIVE: To systematically evaluate the safety and efficacy of laparoscopic surgery versus conservative treatment for appendiceal abscess. METHODS: The databases of CNKI, Wangfang, VIP, PubMed, EMBASE and Cochrane Library were searched to retrieve randomized controlled trials (RCT) or clinical controlled trials (CCT) comparing laparoscopic surgery with conservative treatment for appendiceal abscess published before June 2018. The search terms were Chinese or English. Chinese search terms included appendix, abscess, and laparoscopy; English search terms included appendix, abscess, and laparoscope. References of the resulted papers, related reviews or meta-analysis references were also induded. Literature inclusion criteria: (1)RCT or CCT, whether or not to assign concealment or blinding; (2) appendiceal abscess was diagnosed at admission; (3) laparoscopic group: laparoscopic appendectomy or laparoscopy surgical methods, such as irrigation and drainage, for appendiceal abscess; conservative treatment group: conservative methods, such as antibiotics or percutaneous abscess drainage were used to treat appendiceal abscess. EXCLUSION CRITERIA: (1) review, case report, single cohort study and other non-controlled studies literature; (2) single study sample size ≤ 20; (3) subjects with simple appendicitis or perforation of appendix to form diffuse peritonitis; (4) no valid data available for extraction; (5) repeated publication of the literature. Data were extracted from the included studies, and the Cochrane Collaboration RevMan 5.1.0 version software was used for this meta-analysis. RESULTS: Three RCTs and four CCTs with a total of 591 patients were included in this study. There were 312 patients in the laparoscopic group and 279 patients in the conservative group. Compared with the conservative group, the laparoscopic group had higher uneventful recovery rate (OR=11.91, 95%CI: 4.59 to 30.88, P<0.05), shorter hospital stay (WMD=-2.98, 95%CI: -5.96 to -0.01, P=0.05), lower incidence of recurrent or residual abscess (OR=0.07, 95%CI:0.03 to 0.20, P<0.05), and shorter time to recover to normal condition for body temperature and white blood cell respectively (SMD=-2.12, 95%CI:-2.49 to -1.75, P<0.05; SMD=-2.07, 95%CI: -3.84 to -0.29, P<0.05). However, no significant difference was found in hospital charge(P>0.05). CONCLUSIONS Laparoscopic surgery for appendiceal abscess is safe and feasible. It can improve the recovery with shorter postoperative hospital stay and less recurrent or residual abscess.
