Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Captopril can have nephrotoxic effects, which are largely attributed to accumulated renin and "escaped" angiotensin II (Ang II). Here we test whether angiotensin converting enzyme-1 (ACE1) inhibition damages kidneys via alteration of renal afferent arteriolar responses to Ang II and inflammatory signaling. C57Bl/6 mice were given vehicle or captopril (60 mg/kg per day) for four weeks. Hypertension was obtained by minipump supplying Ang II (400 ng/kg per min) during the second 2 weeks. We assessed kidney histology by periodic acid-Schiff (PAS) and Masson staining, glomerular filtration rate (GFR) by FITC-labeled inulin clearance, and responses to Ang II assessed in afferent arterioles in vitro. Moreover, arteriolar H₂O₂ and catalase, plasma renin were assayed by commercial kits, and mRNAs of renin receptor, transforming growth factor-β (TGF-β) and cyclooxygenase-2 (COX-2) in the renal cortex, mRNAs of angiotensin receptor-1 (AT₁R) and AT₂R in the preglomerular arterioles were detected by RT-qPCR. The results showed that, compared to vehicle, mice given captopril showed lowered blood pressure, reduced GFR, increased plasma renin, renal interstitial fibrosis and tubular epithelial vacuolar degeneration, increased expression of mRNAs of renal TGF-β and COX-2, decreased production of H₂O₂ and increased catalase activity in preglomerular arterioles and enhanced afferent arteriolar Ang II contractions. The latter were blunted by incubation with H₂O₂. The mRNAs of renal microvascular AT₁R and AT₂R remained unaffected by captopril. Ang II-infused mice showed increased blood pressure and reduced afferent arteriolar Ang II responses. Administration of captopril to the Ang II-infused mice normalized blood pressure, but not arteriolar Ang II responses. We conclude that inhibition of ACE1 enhances renal microvascular reactivity to Ang II and may enhance important inflammatory pathways.

OBJECTIVES: To establish a diatom database by analyzing the quatity, species distribution and differences of diatom in water samples of the whole navigable sections of the Beijing-Hangzhou Grand Canal, to provide a reference for the inference of the drowning site. METHODS: Water samples were collected at 22 sites in the navigable sections of the Beijing-Hangzhou Grand Canal (Jining section to Yangzhou Section), and the diatoms at each site were qualitatively and quantitatively analyzed by using graphite digestion-scanning electron microscopy. RESULTS: Sampling site T (Laohuaijiang River Line, Gaoyou City, Yangzhou City, Jiangsu Province) had the highest number of diatoms, while sampling site O (Siyang County, Suqian City, Jiangsu Province) had the lowest number of diatoms, with a large gap of 68 times. At sampling site Q (Jiangpu District, Huaian city, Jiangsu Province), there were 19 species of diatoms. The sampling site O had the least diatoms, with 7 species. There were no significant differences in species evenness and species diversity at each sampling site (P>0.05). Some sampling sites have characterized diatoms, such as Caloneis at station A (Taibai Lake, Weishan County, Shandong Province), Rhoicosphenia at station B (Nanyang Town, Weishan County, Shandong Province), Amphora at station I (Taierzhuang District, Zaozhuang City, Shandong Province) and Epithemia at station J (Pizhou 310 national highway, Xuzhou City, Jiangsu Province). CONCLUSIONS The species richness of diatoms gradually increased from north to south. Diatom species richness and species diversity might be higher in areas with complex environments and large population flow. Climate type has a certain influence on the distribution of diatoms.

BACKGROUND: The neoadjuvant chemotherapy is increasingly used in advanced gastric cancer, but the effects on safety and survival are still controversial. The objective of this meta-analysis was to compare the overall survival and short-term surgical outcomes between neoadjuvant chemotherapy followed by surgery (NACS) and surgery alone (SA) for locally advanced gastric cancer. METHODS: Databases (PubMed, Embase, Web of Science, Cochrane Library, and Google Scholar) were explored for relative studies from January 2000 to January 2021. The quality of randomized controlled trials and cohort studies was evaluated using the modified Jadad scoring system and the Newcastle-Ottawa scale, respectively. The Review Manager software (version 5.3) was used to perform this meta-analysis. The overall survival was evaluated as the primary outcome, while perioperative indicators and post-operative complications were evaluated as the secondary outcomes. RESULTS: Twenty studies, including 1420 NACS cases and 1942 SA cases, were enrolled. The results showed that there were no significant differences in overall survival (P = 0.240), harvested lymph nodes (P = 0.200), total complications (P = 0.080), and 30-day post-operative mortality (P = 0.490) between the NACS and SA groups. However, the NACS group was associated with a longer operation time (P < 0.0001), a higher R0 resection rate (P = 0.003), less reoperation (P = 0.030), and less anastomotic leakage (P = 0.007) compared with SA group. CONCLUSIONS Compared with SA, NACS was considered safe and feasible for improved R0 resection rate as well as decreased reoperation and anastomotic leakage. While unbenefited overall survival indicated a less important effect of NACS on long-term oncological outcomes.

Objective To investigate the sexual behavior types, condom use and influencing factors of gonorrhea patients in Yunnan Province, and to provide evidence for the adjustment of sexually transmitted disease (STD) prevention and control strategy. Methods A cross-sectional study was carried out to investigate gonorrhea patients in 14 STD clinics in 7 more prevalent prefectures (cities) of Yunnan Province. A questionnaire survey was conducted to investigate the socio-demographic and sexual characteristics of the patients in a one-to-one way. Multiple Logistic regression model was used to analyze the influencing factors of sexual behavior. Results A total of 179 cases of gonorrhea were investigated. The average age was (29.01±8.93) years old. 95.53% (171/179) patients were 40 years old and 88.27% were male patients (158/179). Unmarried patients accounted for 55.31% (99/179). Service and self-employed patients accounted for 34.64% (62/179) and 23.46% (42/179) respectively. The rate of sexual intercourse with opposite sex was 98.32% (176/179), the rate of men who have sex with men was 1.68% (3/179) and the rate of having more than two sexual partners was 27.93% (50/179). The rate of sexual intercourse between temporary partners, spouses/fixed partners and commercial partners were 53.07% (95/179), 37.99% (68/179) and 8.94% (16/179) respectively. Recent sexual activity had lower condom use rate, 17.89% (17/95), 19.12% (13/68) and 18.75% (3/16) respectively. The main ways for gonorrhea patients to make temporary partners were friend introductions or gatherings, accounting for 66.32% (63/95). Condom use in male patients was worse than that in female patients (OR=0.234, 95% CI: 0.084-0.656, P=0.006). Conclusions The patients with gonorrhea were mainly unmarried young adults. The main risk behaviors were unprotected behaviors between heterosexual temporary and spouse/fixed sexual partners. The condom use consciousness was generally low. The promotion of safe sex education for young adults should be further strengthened, with special attention to the use of condoms for temporary sexual behavior and spouse/fixed sexual intercourse.

Purpose: Recently, totally laparoscopic gastrectomy has been gradually accepted by surgeons worldwide for gastric cancer treatment. Complete dissection of the lymph nodes and the establishment of the surgical margin are the most important considerations for curative gastric cancer surgery. Previous studies have demonstrated that indocyanine green (ICG)-traced laparoscopic gastrectomy significantly improves the completeness of lymph node dissection. However, it remains difficult to identify the tumor location intraoperatively for gastric cancers that are staged ≤T3. Here, we investigated the feasibility of ICG fluorescence for lymph node mapping and tumor localization during totally laparoscopic distal gastrectomy. Materials and Methods: Preoperative and perioperative data from consecutive patients with gastric cancer who underwent a totally laparoscopic distal gastrectomy were collected and analyzed. The patients were categorized into the ICG (n=61) or the non-ICG (n=75) group based on whether preoperative endoscopic mucosal ICG injection was performed. Results: The ICG group had a shorter operation time and less intraoperative blood loss.Moreover, significantly more lymph nodes were harvested in the ICG group than the non-ICG group. No pathologically positive margin was found and there was no significant difference in either the proximal or distal surgical margins between the 2 groups. Conclusions Near-infrared fluorescence imaging with ICG can be successfully used in totally laparoscopic distal gastrectomy, and it contributes to both the completeness of D2 lymph node dissection and confirmation of the gastric transection line. Well-designed prospective randomized studies are needed in the future to fully validate our findings.

Background: Extralevator abdominoperineal excision (ELAPE) has become a popular procedure for low rectal cancer as compared with abdominoperineal excision (APE). No definitive answer has been achieved whether one is superior to the other. This study aimed to evaluate the safety and efficacy of ELAPE for low rectal cancer with meta-analysis. Methods: The Web of Science, Cochrane Library, Embase, and PubMed databases before September 2019 were comprehensively searched to retrieve comparative trials of ELAPE and APE for low rectal cancer. Pooled analyses of the perioperative variables, surgical complications, and oncological variables were performed. Odds ratio (OR) and mean differences (MD) from each trial were pooled using random or fixed effects model depending on the heterogeneity of the included studies. A subgroup analysis or a sensitivity analysis was conducted to explore the potential source of heterogeneity when necessary. Results: This meta-analysis included 17 studies with 4049 patients, of whom 2248 (55.5%) underwent ELAPE and 1801 (44.5%) underwent APE. There were no statistical differences regarding the circumferential resection margin positivity (13.0% vs. 16.2%, OR = 0.69, 95% CI = 0.42-1.14, P = 0.15) and post-operative perineal wound complication rate (28.9% vs. 24.1%, OR = 1.21, 95% CI = 0.75-1.94, P= 0.43). The ELAPE was associated with lower rate of intraoperative perforation (6.6% vs. 11.3%, OR = 0.50, 95% CI = 0.39-0.64, P < 0.001) and local recurrence (8.8% vs. 20.5%, OR = 0.29, 95% CI = 0.21-0.41, P < 0.001) when compared with APE. Conclusions The ELAPE was associated with a reduction in the rate of intra-operative perforation and local recurrence, without any increase in the circumferential resection margin positivity and post-operative perineal wound complication rate when compared with APE in the surgical treatment of low rectal cancer.

OBJECTIVE: To investigate the risk factors of postoperative pulmonary infection (PPI) in patients over 60 years of age with gastric cancer after radical gastrectomy. METHODS: Clinicopathological data of 373 patients over 60 years of age who underwent radical gastrectomy at Department IV of Gastrointestinal Cancer Center, Peking University Cancer Hospital, from April 2009 to December 2016 were retrospectively collected in this case-control study. The clinicopathological characteristics of patients with postoperative pulmonary infection (including postoperative atelectasis) and those without pulmonary infection were compared. A Student t-test (reported as Mean±SD if data matching normal distribution) or Mann-Whitney U test [reported as median (quartile) if data did not conform to normal distribution] was used to analyze continuous variables. A χ² test or Fisher exact tests (reported as number and percentage) was used for categorical variables. Multivariable logistic regression was used to analyze the risk factors for pulmonary infection after operation of gastric cancer.PPI was defined as postoperative patients with elevated body temperature (>38.0 degrees centigrade) for more than 24 hours; cough and expectoration; positive sputum bacteria culture;recent infiltration, consolidation or atelectasis confirmed by chest imaging examination. RESULTS: Among 373 patients, 50 cases had PPI(13.4%, PPI group), 323 cases had no PPI(86.6%, non-PPI group). There were 39 (78.0%) and 178(55.1%) patients with comorbidities (including hypertension, diabetes and cardiopulmonary disease) preoperatively in PPI and non-PPI group, respectively. The difference between two groups was statistically significant (χ²=9.325,P=0.002). The incidence of preoperative hypoalbuminemia in PPI group was also significantly higher than that in non-PPI group [10.0%(5/50) vs. 3.1% (10/323),χ²=4.098, P=0.048]. Compared to non-PPI group, the rate of total gastrectomy [54.0%(27/50) vs. 34.4% (111/323), χ²=12.501, P=0.002], postoperative wound pain [34.0%(17/50) vs. 11.8% (38/323),χ²=16.928, P<0.001], secondary operation [6.0%(3/50) vs. 0.6% (2/323), χ²=6.032, P=0.014] and the rate of gastric tube removal later than 7 days postoperatively [96.0%(48/50) vs. 84.5%(273/323),χ²=4.811, P=0.028] were significantly higher in PPI group, respectively. The postoperative hospital stay was also prolonged in PPI group [16.0(9.5) days vs. 12.0(5.0) days, U=4 275.0, P<0.001]. Multivariate logistic regression analysis showed that preoperative comorbidities (OR=4.008, 95%CI:1.768-9.086, P=0.001), abdominal infection (OR=3.164, 95%CI:1.075-9.313, P=0.037), and wound pain (OR=3.428, 95%CI:1.557-7.548, P=0.002) were independent risk factors for PPI in patients over 60 years of age with gastric cancer. Furthermore, 50 patients with pulmonary infection were classified according to the length of latency and the type of infection. The patients with PPI latency ≤ 3 days were classified as early onset (34 cases, 68.0%), and those with latency ≥ 4 days as delayed onset (16 cases, 32.0%); PPI combined with surgical infection (including anastomotic leakage, abdominal infection, duodenal stump leakage, wound infection, etc.) was classified into mixed infection group (13 cases, 26.0%), with non-surgical infection as simple infection group (37 cases, 74.0%). The results showed that the pulmonary infection occurred 0 to 12 days (median 3 days) before surgical infection in mix infection group. The incidence of previous chronic obstructive pulmonary disease (COPD) in patients with early onset was significantly higher than that in patients with delayed onset [17.6%(6/34) vs. 0, χ²=5.005, P=0.025], and the incidence of mixed infection in patients with delayed onset was significantly higher than that in patients with early onset [50%(8/16) vs. 14.7%(5/34), χ²=6.730, P=0.009],but there was no significant difference in postoperative hospital stay between the two groups[17.0(9.8) days vs. 14.0(9.5) days, U=224.0, P=0.317]. CONCLUSIONS Postoperative pulmonary infection is common in gastric cancer patients over 60 years of age. Preoperative comorbidities, abdominal infection and wound pain are independent risk factors for postoperative pulmonary infection. Pulmonary infection within 3 days after operation is associated with preoperative COPD. For patients suffering from PPI after the 4th day,attentions should be paid to abdominal infection and anastomotic leakage.

Metformin (MET), an antidiabetic agent, also has antioxidative effects in metabolic-related hypertension. This study was designed to determine whether MET has anti-hypertensive effects in salt-sensitive hypertensive rats by inhibiting oxidative stress in the hypothalamic paraventricular nucleus (PVN). Salt-sensitive rats received a high-salt (HS) diet to induce hypertension, or a normal-salt (NS) diet as control. At the same time, they received intracerebroventricular (ICV) infusion of MET or vehicle for 6 weeks. We found that HS rats had higher oxidative stress levels and mean arterial pressure (MAP) than NS rats. ICV infusion of MET attenuated MAP and reduced plasma norepinephrine levels in HS rats. It also decreased reactive oxygen species and the expression of subunits of NAD(P)H oxidase, improved the superoxide dismutase activity, reduced components of the renin-angiotensin system, and altered neurotransmitters in the PVN. Our findings suggest that central MET administration lowers MAP in salt-sensitive hypertension via attenuating oxidative stress, inhibiting the renin-angiotensin system, and restoring the balance between excitatory and inhibitory neurotransmitters in the PVN.
