ObjectiveTo observe the clinical efficacy of tonifying kidney and replenishing essence on asthenozoospermia patients with the syndrome of kidney essence deficiency and the effects of this method on the adenosine 5′-monophosphate-activated protein kinase （AMPK）/mammalian target of rapamycin complex 1 （mTORC1） signaling pathway. MethodsSeventy-two eligible asthenozoospermia patients with the syndrome of kidney essence deficiency treated in the Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from February 2023 to January 2024 were selected and randomly assigned into an observation group and a control group， with 36 patients in each group. The observation group received oral administration of Guilu Tianjing capsules， while the control group received oral administration of L-carnitine oral solution. The treatment course lasted for 4 weeks in both groups. The observed indicators included sperm progressive motility rate （PR）， total sperm motility （PR+NP）， percentage of normal mitochondrial membrane potential （MMP）， and traditional Chinese medicine （TCM） symptom scores before and after treatment in both groups. A three-month follow-up was instituted to record the conception status of the patients’ spouses. Additionally， eight patients were randomly selected from the eligible patients in the observation group， and four healthy males with normal semen routine examination results were included as the control group for the determination of protein expression. Western blotting was conducted to assess the expression of AMPK， phosphorylated （p）-AMPK， regulatory-associated protein of mTOR （RAPTOR） and p-RAPTOR， and PTEN-induced putative kinase 1 （PINK1） in sperms from the observation group before and after treatment， as well as in the sperms of the control group. ResultsThe pregnancy rate of spouses in the observation group was 9.09% （3/33）， which was higher than that （3.33%， 1/30） in the control group. The total response rate was 84.8% （28/33） in the observation group and 66.7% （20/30） in the control group， with no statistically significant difference. After treatment， both groups were improved considering PR， PR+NP， MMP， and TCM symptom scores （P<0.01）. Moreover， the observation group exhibited more pronounced decreases in TCM symptom scores than the control group （P<0.05）， while the changes in PR， PR+NP， and MMP showed no statistical significance between groups. Compared with the control group， the asthenozoospermia group exhibited upregulations in phosphorylation levels of AMPK and RAPTOR and protein level of PINK （P<0.01）. The administration of Guilu Tianjing Capsules led to downregulations in the phosphorylation levels of AMPK and RAPTOR and protein level of PINK1 （P<0.01）. However， the protein levels of AMPK and RAPTOR demonstrated no significant difference between before and after treatment. During the study period， neither group of patients exhibited any notable adverse reactions. ConclusionGuilu Tianjing capsules can enhance the sperm motility and percentage of normal mitochondrial membrane potential in asthenozoospermia patients with the syndrome of kidney essence deficiency by downregulating the AMPK/mTORC1 signaling pathway， lowering the protein level of PINK1， and inhibiting excessive activation of mitophagy.

Objective: To investigate the epidemiological characteristics of human brucellosis in Jiande City, Zhejiang Province from 2005 to 2024, so as to provide the evidence for strengthening the prevention and control of brucellosis. Methods: Data on brucellosis cases and surveillance in Jiande City from 2005 to 2024 were collected through the Chinese Disease Prevention and Control Information System, the annual brucellosis surveillance reports from the Jiande Center for Disease Control and Prevention, and the annual summaries of brucellosis prevention and control efforts. The epidemiological characteristics of human brucellosis were analyzed using a descriptive epidemiological method. Results: A total of 1 125 individuals were monitored in Jiande City from 2005 to 2024, with 18 seropositive cases identified and the seropositivity rate of 1.60%. The average annual seropositivity rate from 2015 to 2024 was 3.35%, which was significantly higher than that of 0.57% from 2005 to 2014 (P<0.05). There were 10 confirmed brucellosis cases and 8 asymptomatic infections, with no reported deaths. The peak incidence occurred between March and August. Among the 16 towns (streets) in Jiande City, 8 reported brucellosis cases. Of the brucellosis cases, 14 were male and 4 were female, with a male-to-female ratio of 3.5∶1. The majority of cases (13 cases) were aged between 40 and 60 years. Occupational exposure was identified in 16 cases, all of whom were infected through direct hand contact with the excreta, secretions, or animal products of infected sheep or cattle. The primary source of infection was sheep, followed by cattle. Five strains of Brucella were isolated and cultured, all identified as Brucella melitensis biovar 3. Conclusions The brucellosis epidemic in Jiande City remained at a sporadic and low prevalence level from 2005 to 2024, with an increasing trend observed from 2015 to 2024. Male occupational groups aged 40 to 60 years were the key population for brucellosis prevention and control, and sheep were the primary source of infection.

Objective:To investigate the clinical effect of the modified vertical rectus abdominis myocutaneous flap in repairing the skin and soft tissue defect after abdominoperineal resection for rectal cancer.Methods:This study was a retrospective observational study. From June 2019 to July 2022, five male patients with low rectal cancer who were conformed to the inclusion criteria were admitted to the Department of Basic Surgery of Xiangya Hospital of Central South University, with ages ranging from 65 to 70 years and the sizes of the perianal skin ulcers ranging from 5 cm×4 cm to 11 cm×9 cm, and all of them underwent abdominoperineal resection. The secondary skin and soft tissue defects in the perineum with an area of 8 cm×6 cm-14 cm×12 cm (with the depth of pelvic floor dead space being 10-15 cm) were repaired intraoperatively with transplantation of modified vertical rectus abdominis myocutaneous flaps with the skin area being 9 cm×7 cm-16 cm×12 cm, the volume of the muscle being 18 cm×10 cm×5 cm-20 cm×12 cm×5 cm, and the vessel pedicle being 18-20 cm in length. During the operation, most of the anterior sheath of the rectus abdominis muscle was retained, the flap was transferred to the recipient area through the abdominal cavity, the remaining anterior sheaths of the rectus abdominis muscle on both sides of the donor area were repeatedly folded and sutured, the free edge of the transverse fascia of the abdomen was sutured with the anterior sheath of the rectus abdominis muscle, and the donor area skin was directly sutured. After the operation, the survival of the transplanted myocutaneous flap was observed. The occurrence of complications in the perineal recipient area was recorded within 2 weeks after the operation. The recovery of the perineal recipient area and the abdominal donor area was observed during follow-up, and the occurrence of complications in the donor area of the abdomen as well as the recurrence of tumors and metastasis were recorded.Results:All transplanted myocutaneous flaps in 5 patients survived after surgery. One patient had dehiscence of the incision in the perineal recipient area 2 days after surgery, which healed after 7 d with intermittent dressing changes and routine vacuum sealing drainage treatment. In the other 4 patients, no complications such as incisional rupture, incisional infection, or fat liquefaction occurred in the perineal recipient area within 2 weeks after surgery. Follow-up for 6-12 months after discharge showed that the skin of the perineal recipient area had good color, texture, and elasticity, and was not bloated in appearance; linear scars were left in the perineal recipient area and the abdominal donor area without obvious scar hyperplasia or hyperpigmentation; no complications such as incisional rupture, incisional infection, intestinal adhesion, intestinal obstruction, or weakening of the abdominal wall strength occurred in the abdominal donor area, and the abdominal appearance was good with no localized bulge or formation of abdominal hernia; there was no local recurrence of tumor or metastasis in any patient.Conclusions:The surgical approach of using the modified vertical rectus abdominis myocutaneous flap to repair the skin and soft tissue defects after abdominoperineal resection for rectal cancer is relatively simple in operation, can achieve good postoperative appearances of the donor and recipient areas with few complications, and is worthy of clinical promotion.

Objective:To investigate the effect of electroacupuncture treatment on the integrity of myelin and the related molecules in the spinal dorsal horn of neuropathic pain model rat.Methods:Totally 32 SPF grade Sprague-Dawley rats were randomly divided into 4 groups: sham group, pain model group, electroacupuncture group and sham electroacupuncture group, with 8 rats in each group. Neuropathic pain model was established by right sciatic nerve ligation. Electroacupuncture stimulation of Huantiao point and Yanglingquan point was started from 1 day after surgery, 30 min/d, and lasted for 14 days. The paw withdraw mechanical threshold (PWMT) were tested before surgery, 3 days, 7 days and 14 days after surgery. Immunofluorescence was used to detect myelin basic protein (MBP) in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn and Western blot was used to measure the expression of β-secreatase 1(BACE1), neuregulin 1 type Ⅲ (NRG1 Ⅲ) and phosphorylated ErbB receptor tyrosine kinase 2 (p-ErbB2) at 14 days after surgery.SPSS 24.0 was used for statistical analysis.Repeated measurement ANOVA was used for behavioral analysis and one-way ANOVA followed by Bonferroni test was used for Western blot and immunofluorescence data analysis.Results:(1) The results of pain behaviors showed that the interaction effect of time and group on PWMT was significant ( F=29.817, P<0.001), and both the time main effect ( F=240.598, P<0.001) and group main effect ( F=304.291, P<0.001) were significant. There were no significant differences among 4 groups before surgery. Compared with pain model group, the PWMT of electroacupuncture group were significantly increased at 3 days ((16.87±1.82) g, (11.31±1.36) g), 7 days ((15.09±1.75) g, (10.33±0.73) g) and 14 days ((15.07±1.49) g, (9.87±0.98) g) after surgery (all P<0.01). (2)The difference of the intensity of MBP in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn staining was significant among 4 groups ( F=92.06, P<0.001). Compared with sham group, the intensity of MBP staining in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn in pain model group was significantly decreased ((13.26±1.90)%, (36.37±0.68)%) ( P<0.01) ). Compared with pain model group, the intensity of MBP staining in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn in electroacupuncture group ((28.21±3.15)%) was significantly increased after electroacupuncture treatment ( P<0.01). (3) The differences of the expressions of BACE1, NRG1 Ⅲ and p-ErbB2 in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn were significant among the 4 groups ( F=31.04, 21.20, 11.74, all P<0.01). Compared with sham group, the expressions of BACE1, NRG1 Ⅲ and p-ErbB2 in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn in pain model group were significantly downregulated (BACE1 (0.42±0.09), (1.16±0.13); NRG1 Ⅲ (0.54±0.05), (1.00±0.10); p-ErbB2 (0.73±0.06), (1.02±0.15) ) (all P<0.05). Compared with pain model group, the expression of BACE1 (0.86±0.09), NRG1 Ⅲ (0.81±0.05) and p-ErbB2 (1.12±0.04) in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn in electroacupuncture group were upregulated(all P<0.05). Conclusion:Electroacupuncture treatment could relieve neuropathic pain, improve the demyelination and upregulate the expressions of myelin-related proteins in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-positive bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-positive bacteria from blood cultures in member hospitals of National Bloodstream Infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:A total of 3 163 strains of Gram-positive pathogens were collected from 51 member units，and the top five bacteria were Staphylococcus aureus（ n=1 147，36.3%），coagulase-negative Staphylococci（ n=928，29.3%）， Enterococcus faecalis（ n=369，11.7%）， Enterococcus faecium（ n=296，9.4%）and alpha-hemolyticus Streptococci（ n=192，6.1%）. The detection rates of methicillin-resistant Staphylococcus aureus（MRSA）and methicillin-resistant coagulase-negative Staphylococci（MRCNS）were 26.4%（303/1 147）and 66.7%（619/928），respectively. No glycopeptide and daptomycin-resistant Staphylococci were detected. The sensitivity rates of Staphylococcus aureus to cefpirome，rifampin，compound sulfamethoxazole，linezolid，minocycline and tigecycline were all >95.0%. Enterococcus faecium was more prevalent than Enterococcus faecalis. The resistance rates of Enterococcus faecium to vancomycin and teicoplanin were both 0.5%（2/369），and no vancomycin-resistant Enterococcus faecium was detected. The detection rate of MRSA in southern China was significantly lower than that in other regions（ χ2=14.578， P=0.002），while the detection rate of MRCNS in northern China was significantly higher than that in other regions（ χ2=15.195， P=0.002）. The detection rates of MRSA and MRCNS in provincial hospitals were higher than those in municipal hospitals（ χ2=13.519 and 12.136， P<0.001）. The detection rates of MRSA and MRCNS in economically more advanced regions（per capita GDP≥92 059 Yuan in 2022）were higher than those in economically less advanced regions（per capita GDP<92 059 Yuan）（ χ2=9.969 and 7.606， P=0.002和0.006）. Conclusions:Among the Gram-positive pathogens causing bloodstream infections in China， Staphylococci is the most common while the MRSA incidence decreases continuously with time；the detection rate of Enterococcus faecium exceeds that of Enterococcus faecalis. The overall prevalence of vancomycin-resistant Enterococci is still at a low level. The composition ratio of Gram-positive pathogens and resistant profiles varies slightly across regions of China，with the prevalence of MRSA and MRCNS being more pronounced in provincial hospitals and areas with a per capita GDP≥92 059 yuan.

Objective:To investigate the satisfaction levels of the rural elderly in Dafeng district of Yancheng, Jiangsu province with the contracted family doctor services, and to identify the factors that influence their satisfaction.The findings of this study will provide valuable insights for improving the quality of the contracted family doctor services offered to the rural elderly population.Methods:The study utilized the stratified cluster sampling method to select elderly individuals aged 60 years and above from Dafeng district, Yancheng city for a questionnaire survey.Specifically, the study focused on elderly individuals who had participated in contracted family doctor services for more than six months.The survey aimed to gather information on the elderly population's general situation, as well as their understanding, utilization, and satisfaction with contracted family doctor services.The satisfaction of contracted family doctor services was analyzed using the chi square test and multivariate Logistic regression to identify the influencing factors.Results:The study surveyed 385 elderly individuals from rural areas who had contracted family doctor services.The results showed that 88.3%(340/385)of respondents were satisfied with the services they received.Additionally, 99.2%(382/385)of those surveyed were aware of the contracted family doctor services, and 81.8%(315/385)had received basic medical services from their signed-up doctors.The results of a multifactor analysis that examined the factors influencing the overall satisfaction of elderly patients with their contracted family doctor services revealed several significant factors.Specifically, being female( OR=2.557, 95% CI: 1.122-5.830, P=0.026)and unmarried( OR=7.355, 95% CI: 1.850-29.237, P=0.005), supporting the contracted family doctor services system( OR=18.442, 95% CI: 1.732-195.973, P=0.016), believing that the contracted medical institutions had excellent hardware facilities( OR=9.918, 95% CI: 2.313-42.526, P=0.002)and providing high-quality health services for the elderly( OR=8.723, 95% CI: 1.556-48.908, P=0.014), as well as experiencing improved health status after signing the contract( OR=5.006, 95% CI: 1.764-14.201, P=0.002)were all significant factors influencing their satisfaction.These findings suggest that these factors are important considerations for improving the satisfaction of elderly patients with their contracted family doctor services. Conclusions:The contracted family doctor services provided in Dafeng district, Yancheng city have been well received by the rural elderly population.Factors such as gender, marital status, attitude towards the contracted family doctor services system, improvements in health status after contracting the service, quality of the hardware facilities at the contracted medical institution, and availability of health services specifically tailored for the elderly all play a role in determining the level of satisfaction among the contracted elderly population.To better serve the elderly population, it is crucial that we prioritize their needs.This can be achieved by improving the level of "suitable aging" in the contracted services and enhancing the satisfaction of family doctors who provide these services.

Objective:To evaluate the anesthetic effect of remazolam when combined with sufentanil in elderly patients with liver cirrhosis and esophageal and gastric varices undergoing endoscopic sclerotherapy.Methods:A total of 150 cirrhotic patients with liver cirrhosis and esophageal and gastric varices, regardless of gender, aged 65-80 yr, with body mass index of 18-24 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱor Ⅲ, who underwent endoscopic sclerotherapy under non-intubated general anesthesia from March 2022 to September 2023 in our hospital, were selected and divided into 2 groups ( n=75 each) by a random number table method: sufentanil plus propofol group (PS group) and sufentanil plus remazolam group (RS group). Anesthesia was induced with intravenous propofol 1-2 mg/kg and sufentanil 0.1 μg/kg and maintained by intravenous infusion of propofol 4-10 mg·kg -1·h -1 in PS group. Anesthesia was induced with intravenous remimazolam 0.1-0.2 mg/kg and sufentanil 0.1 μg/kg and was maintained with intravenous infusion of remimazolam 0.5-2.0 mg·kg -1·h -1 in RS group. BIS values were maintained between 40 and 60 during operation in both groups. Endoscopy was placed when the patients lost consciousness (modified observer′s assessment of alertness/sedation score ≤1). Sclerosing agent laurosinol injection was injected into esophageal submucosal varices in both groups. The time to loss of consciousness and recovery of consciousness, intraoperative body movement and cardiovascular events, and postoperative hypoxemia and nausea and vomiting were recorded. The operator-patient satisfaction was assessed by the visual analogue scale. Results:Compared with PS group, no significant changes were found in the incidence of intraoperative bradycardia, time to loss of consciousness and time to recovery of consciousness( P>0.05), the incidence of intraoperative hypotension was significantly decreased, the incidence of postoperative hypoxemia and nausea and vomiting was decreased, and the satisfaction scores for operators and patients were increased in RS group ( P<0.05). No obvious body movement was found in the two groups. Conclusions:Sufentanil combined with remifentanil provides better anesthetic effect than sufentanil combined with propofol in elderly patients with esophageal and gastric varices undergoing endoscopic sclerotherapy.

Taking the reform of payment methods based on diagnosis related groups as an opportunity, implementing performance management based on disease groups is an important lever to promote the improvement of hospital diagnosis and treatment level and high-quality development. In 2023, a tertiary comprehensive hospital introduced benchmarking management into performance management, using the average days of stay, drug costs, and consumables costs of the disease group as cost benchmark indicators. The cost benchmark values for each disease group was determined based on the big data of the disease group of the tertiary comprehensive hospital in the region and the clinical pathway management goals of the hospital. Through multidimensional and multi-level comparative analysis of the hospital′s historical values and regional big data distribution values of the benchmark indicators for each disease group, the cost benchmark values for each disease group was determined. The hospital has established a performance reward and punishment mechanism based on the benchmark value of disease group costs, and at the same time, established a performance management communication mechanism to promote relevant departments and medical groups to improve their management against the benchmark. In addition, with changes in the external environment and internal practices, the cost benchmark value of the disease group was dynamically optimized, forming a closed-loop management system that included establishing benchmarks, comparing benchmarks, achieving benchmarks, and optimizing benchmarks. Since the implementation of performance management based on disease group cost benchmarking in March 2023, the hospital′s case mix index has increased from 1.52 in March to 1.54 in September; The average days of stay decreased from 6.22 days to 5.90 days; The monthly payment weight has increased from 18 103 to 18 558; The average hospitalization cost has decreased from 16 724 yuan/person to 15 278 yuan/person, mainly due to the decrease in drug and consumables costs. The proportion of drug costs has decreased from 27.45% to 26.32%, the proportion of consumables costs has decreased from 28.75% to 26.85%, and the proportion of medical service revenue has increased from 24.64% to 26.08%; The proportion of low magnification cases decreased from 9.09% to 8.24%; The medical insurance payment rate has increased from 99.3% to 107.0%; The job satisfaction of physicians has increased from 70.00% in 2022 to 76.77% in 2023, which can provide reference for performance management practices in other hospitals.
