Objective: To investigate the impact of non-high-density lipoprotein cholesterol (non-HDL-C) level on major adverse cardiovascular and cerebrovascular events (MACCE) and all-cause mortality in the Kailuan Study cohort undergoing revascularization. Methods: This is a prospective cohort study, with participants from the Kailuan Study cohort who participated in physical examinations from 2006 to 2020 and received revascularization therapy for the first time. According to the level of non-HDL-C, the study subjects were divided into 3 groups:<2.6 mmol/L group, 2.6-<3.4 mmol/L group, and≥3.4 mmol/L group. Annual follow-up was performed, and the endpoint events were MACCE and all-cause mortality. Cox proportional regression model was implemented to estimate the impact on MACCE and all-cause mortality associated with the different non-HDL-C groups. The partial distributed risk model was used to analyze the impact of different non-HDL-C levels on MACCE event subtypes, and death was regarded as a competitive event. The restricted cubic spline regression model was used to explore the dose-response relationship between non-HDL-C level and all-cause mortality, MACCE and its subtypes. Results: A total of 2 252 subjects were enrolled in the study, including 2 019 males (89.65%), aged (62.8±8.3) years, the follow-up time was 5.72 (3.18, 8.46) years. There were 384 cases(17.05%) of MACCE and 157 cases(6.97%) of all-cause mortality. Compared with patients with non-HDL-C≥3.4 mmol/L, patients with non-HDL-C<2.6 mmol/L were associated with a 38% reduced risk of MACCE after revascularization [HR=0.62(95%CI: 0.48-0.80)]. Every 1 mmol/L decrease in non-HDL-C was associated with a 20% reduction in the risk of MACCE [HR=0.80(95%CI: 0.73-0.88)]. The results of restricted cubic spline also showed that non-HDL-C levels after revascularization therapy were positively correlated with MACCE events (overall association P<0.001, non-linear association P=0.808). For all-cause mortality, compared to the non-HDL-C≥3.4 mmol/L group, the HR for all-cause mortality after revascularization in non-HDL-C<2.6 mmol/L group was 0.67(95%CI: 0.46-1.01). Every 1 mmol/L decrease in non-HDL-C was associated with a 15% reduction in the risk of all-cause mortality [HR=0.85(95%CI: 0.73-0.99)]. The restricted cubic spline results showed a linear association between non-HDL-C levels after revascularization therapy and the risk of all-cause mortality (overall association P=0.039, non-linear association P=0.174). Conclusion: The decrease in non-HDL-C levels after revascularization were significantly associated with a reduced risk of MACCE and all-cause mortality.

Nocardiosis can be caused by various Nocardia spp., including Nocardia asteroides, Nocardia brasiliensis, Nocardia cyriacigeorgica, Nocardia farcinica and Nocardia otitidiscaviarum. As compared with the other Nocardia spp., Nocardia otitidiscaviarum appears to be rare which can spread through the bloodstream and affect multiple organs. The disease is usually seen in immunocompromised patients' but may also occur in immunocompetent patients. The clinical symptoms and laboratory and imaging examinations of the disease are nonspecific.Here, we reported a case of disseminated nocardiosis caused by infection with Nocardiosis otitidiscaviarum in an immunocompetent host to improve the knowledge and diagnosis of nocardiosis.

Objective: To analyze the survival time of reported HIV/AIDS and influencing factors of Yunnan Province from 1989 to 2021. Methods: The data were extracted from the Chinese HIV/AIDS comprehensive response information management system. The retrospective cohort study was conducted. The life table method was applied to calculate the survival probability. Kaplan-Meier was used to draw survival curves in different situations. Furthermore, the Cox proportion hazard regression model was constructed to identify the factors related to survival time. Results: Of the 174 510 HIV/AIDS, the all-cause mortality density was 4.23 per 100 person-years, the median survival time was 20.00 (95%CI:19.52-20.48) years, and the cumulative survival rates in 1, 10, 20, and 30 years were 90.75%, 67.50%, 47.93% and 30.85%. Multivariate Cox proportional risk regression model results showed that the risk of death among 0-14 and 15-49 years old groups were 0.44 (95%CI: 0.34-0.56) times and 0.51 (95%CI:0.50-0.52) times of ≥50 years old groups. The risk for death among the first CD4+T lymphocytes counts (CD4) counts levels of 200-349 cells/µl, 350-500 cells/µl and ≥501 cells/µl groups were 0.52 (95%CI: 0.50-0.53) times, 0.41 (95%CI: 0.40-0.42) times and 0.35 (95%CI: 0.34-0.36) times of 0-199 cells/µl groups. The risk of death among the cases that have not received antiretroviral therapy (ART) was 11.56 (95%CI: 11.26-11.87) times. The risk for death among the cases losing to ART, stopping to ART, both losing and stopping ART was 1.66 (95%CI:1.61-1.72) times, 2.49 (95%CI:2.39-2.60) times, and 1.65 (95%CI:1.53-1.78) times of the cases on ART. Conclusions: The influencing factors for the survival time of HIV/AIDS cases were age at diagnosis in Yunnan province from 1989 to 2021. The first CD4 counts levels, antiretroviral therapy, and ART compliance. Early diagnosis, early antiretroviral therapy, and increasing ART compliance could extend the survival time of HIV/AIDS cases.

OBJECTIVE: To describe the secular trends of age at menarche and age at natural menopause of women from a county of Shandong Province. METHODS: Based on the data of the Premarital Medical Examination and the Cervical Cancer and Breast Cancer Screening of the county, the secular trends of age at menarche in women born in 1951 to 1998 and age at menopause in women born in 1951 to 1975 were studied. Joinpoint regression was used to identify potential inflection points regarding the trend of age at menarche. Average hazard ratios (AHR) of early menopause among women born in different generations were estimated by performing multivariate weighted Cox regression. RESULTS: The average age at menarche was (16.43±1.89) years for women born in 1951 and (13.99±1.22) years for women born in 1998. The average age at menarche was lower for urban women than that for rural women, and the higher the education level, the lower the average age at menarche. Joinpoint regression analysis identified three inflection points: 1959, 1973 and 1993. The average age at menarche decreased annually by 0.03 (P < 0.001), 0.08 (P < 0.001), and 0.03 (P < 0.001) years respectively for women born during 1951-1959, 1960-1973, and 1974-1993, while it remained stable for those born during 1994-1998 (P=0.968). As for age at menopause, compared with women born during 1951-1960, those born during 1961-1965, 1966-1970 and 1971-1975 showed a gradual decrease in the risk of early menopause and a tendency to delay the age at menopause. The stratified analysis presented that the risk of early menopause gradually decreased and the age of menopause showed a significant delay among those with education level of junior high school and below, but this trend was not obvious among those with education level of senior high school and above, where the risk of early menopause decreased and then increased among those with education level of college and above, and the corresponding AHRs were 0.90 (0.66-1.22), 1.07 (0.79-1.44) and 1.14 (0.79-1.66). CONCLUSION: The age at menarche for women born since 1951 gradually declined until 1994 and leveled off, with a decrease of nearly 2.5 years in these years. The age at menopause for women born between 1951 and 1975 was generally delayed over time, but the trend of first increase and then decrease was observed among those with relatively higher education levels. In the context of the increasing delay in age at marriage and childbearing and the decline of fertility, this study highlights the necessity of the assessment and monitoring of women' s basic reproductive health status, especially the risk of early menopause.

Objective: To investigate the response characteristics of patients with locally advanced/metastatic non-squamous non-small cell lung cancer (nsq-NSCLC) treated with tislelizumab in combination with chemotherapy in the first line. Methods: Patients with nsq-NSCLC who achieved complete or partial remission after treatment with tislelizumab in combination with chemotherapy or chemotherapy alone in the RATIONALE 304 study, as assessed by an independent review board, were selected to analyze the response characteristics and safety profile of the responders. Time to response (TTR) was defined as the time from randomization to the achievement of first objective response. Depth of response (DpR) was defined as the maximum percentage of tumor shrinkage compared with the sum of the baseline target lesion length diameters. Results: As of January 23, 2020, 128 patients treated with tislelizumab in combination with chemotherapy achieved objective tumor response (responders), representing 57.4%(128/223) of the intention-to-treat population, with a TTR of 5.1 to 33.3 weeks and a median TTR of 7.9 weeks. Of the responders (128), 50.8%(65) achieved first remission at the first efficacy assessment (week 6), 31.3%(40) at the second efficacy assessment (week 12), and 18.0%(23) at the third and subsequent tumor assessments. The percentages of responders who achieved a depth of tumor response of 30% to <50%, 50% to <70% and 70% to 100% were 45.3%(58/128), 28.1%(36/128) and 26.6%(34/128), respectively, with median progression-free survival (PFS) of 9.0 months (95% CI: 7.7 to 9.9 months), 11.5 months (95% CI: 7.7 months to not reached) and not reached (95% CI: 11.8 months to not estimable), respectively. Tislelizumab plus chemotherapy were generally well tolerated in responders with similar safety profile to the overall safety population. Conclusion: Among responders to tislelizumab in combination with chemotherapy for nsq-NSCLC, 82.0%(105/128) achieves response within the first two tumor assessments (12 weeks) and 18.0%(23/128) achieves response at later (18 to 33 weeks) assessments, and there is a trend toward prolonged PFS in responders with deeper tumor response.

Objective: To investigate clinical and imaging parameters to predict blood loss and cranial nerve injury (CNI) following carotid body paraganglioma (CBP) resection. Methods: A retrospective examination of clinical and imaging data was conducted on 63 patients who underwent CBP resection at Xiangya Hospital of Central South University from January 2016 to December 2022, including 23 males and 40 females, aged 26-87 years old. Three imaging parameters including tumor volume, the angle of contact with the internal carotid artery (ICA), and the distance to the base of skull (DTBOS) were gauged using the IMEDPACS software on CTA and MR imaging. The predictive efficacies of age, gender, Shamblin classification, and three imaging parameters for blood loss and CNI following surgery were analysed. Logistic composite parameter models were constructed and their predictive validity was assessed. Results: Multivariate logistic regression analysis underscored that only tumor volume (OR=1.381,95%CI:1.167-1.507,P=0.001) showed significant statistical correlations with blood loss following surgery. Area under curve (AUC) values of 0.910 for receiver operating characteristic (ROC) curves showed a sensitivity of 1.000 and a specificity of 0.694. Tumor volume (OR=1.126,95%CI:1.030-1.231, P=0.002) and DTBOS (OR=0.225,95%CI:0.081-0.630,P=0.005) were significantly associated with postoperative CNI. The analysis of logistic composite model showed AUC values for tumor volume, DTBOS and combination of the two parameters were 0.858, 0.788, and 0.872, respectively. The model for combination of tumor volume and DTBOS also proved superior in predicting postoperative CNI (Z=3.106, P<0.001), with a sensitivity of 0.833 and a specificity of 0.769. Conclusions: Tumor volume and DTBOS emerged as effective predictors for blood loss and/or CNI in patients with CBP resection. Moreover, the logistic composite parameter model outclassed single-parameter models in terms of their predictive clinical value.

Objective: To investigate the value of robot-assisted laparoscopic indocyanine green sentinel lymph node (SLN) tracing in treating endometrial carcinoma. Methods: Thirty-two patients with early-staging endometrial carcinoma were operated with laparoscopic comprehensive staging laparotomy from January 2019 to December 2021. At the same time, the SLN detection was performed by near-infrared fluorescence imaging tracer technology, in which the tracer was indocyanine green. Sixteen cases were injected with indocyanine green before laparoscopic surgery, and 16 cases were injected with indocyanine green before robot-assisted laparoscopic surgery. The operation index, postoperative complications, prognosis, and lymph node dissection were compared between the two groups. Results: (1) The mean age of patients in the robot group was (54.7±8.1) years old, and was (54.9±8.8) years old in the laparoscopic group. There were no significant difference between the two groups (t=0.06, P=0.951). (2) Intraoperative blood loss [(131±40) vs (169±57) ml], hemoglobin difference before and after surgery [(11.2±5.4) vs (15.5±5.7) g/L], the length of stay after operation [(6.2±1.3) vs (8.6±1.4) days] between the robot group and the laparoscopic group were compared, and the differences were statistically significant (all P<0.05). (3) SLNs were detected in all 16 patients in the robotic group, and a total of 41 SLNs were detected. SLNs were detected in 15 of the 16 patients in the laparoscopy group, and a total of 40 SLNs were detected. Compared with the laparoscopic group (15/16), the total detection rate of SLN in the robotic group (16/16), there were no statistical significance (χ2=1.03, P=0.310). Compared with the laparoscopic group (7/15), the SLN bilateral detection rate in the robotic group (10/16), there were also no significant difference (χ2=0.78, P=0.376). The number of lymph nodes detected in surgery group (16.6±4.1) were lower than those in the laparoscopy surgery group (21.0±7.1), while there were no statistically difference between the two groups (χ2=2.01, P=0.054). There was no tumor metastasis in the resected lymph nodes and SLN between the two groups. The false negative rate of SLN in diagnosing endometrial cancer postoperative lymph node metastasis was 0, and the negative predictive value was 100%. (4) The pelvic and retroperitoneal lymph nodes were divided into five regions, which were the left pelvis, the right pelvis, the presacral region, the deep inguinal region, and the abdominal aorta. The numbers of SLN of unilateral detection and bilateral pelvic detection between two groups showed no significant differences (all P>0.05). The left pelvis had the most SLN imaging in both groups, followed by the right pelvis, para-aortic, and deep groin. (5) There was one patient in both robotic group and laparoscopic group with postoperative complications, which were urinary retention and pelvic lymph node cyst respectively. There were no significant differences in the incidence of complications between the two groups (χ2=0.97, P=1.000). The median follow-up time after operation was 14 months (range 6-24 months). During the follow-up period, no local recurrence or distant metastasis was found between the two groups of endometrial cancer patients. Conclusions: Compared with the laparoscopic group, the robot group has less intraoperative blood loss and shorter postoperative hospital stay. The bilateral detection rate of SLN in the group was better than that of laparoscopy.

Chaetomiaceae comprises phenotypically diverse species, which impact biotechnology, the indoor environment and human health. Recent studies showed that most of the traditionally defined genera in Chaetomiaceae are highly polyphyletic. Many of these morphology-based genera, such as Chaetomium, Thielavia and Humicola, have been redefined using multigene phylogenetic analysis combined with morphology; however, a comprehensive taxonomic overview of the family is lacking. In addition, the phylogenetic relationship of thermophilic Chaetomiaceae species with non-thermophilic taxa in the family is largely unclear due to limited taxon sampling in previous studies. In this study, we provide an up-to-date overview on the taxonomy and phylogeny of genera and species belonging to Chaetomiaceae, including an extensive taxon sampling of thermophiles. A multigene phylogenetic analysis based on the ITS (internal transcribed spacers 1 and 2 including the 5.8S nrDNA), LSU (D1/D2 domains of the 28S nrDNA), rpb2 (partial RNA polymerase II second largest subunit gene) and tub2 (ß-tubulin gene) sequences was performed on 345 strains representing Chaetomiaceae and 58 strains of other families in Sordariales. Divergence times based on the multi-gene phylogeny were estimated as aid to determine the genera in the family. Genera were delimited following the criteria that a genus must be a statistically well-supported monophyletic clade in both the multigene phylogeny and molecular dating analysis, fall within a divergence time of over 27 million years ago, and be supported by ecological preference or phenotypic traits. Based on the results of the phylogeny and molecular dating analyses, combined with morphological characters and temperature-growth characteristics, 50 genera and 275 species are accepted in Chaetomiaceae. Among them, six new genera, six new species, 45 new combinations and three new names are proposed. The results demonstrate that the thermophilic species fall into seven genera (Melanocarpus, Mycothermus, Remersonia, Thermocarpiscus gen. nov., Thermochaetoides gen. nov., Thermothelomyces and Thermothielavioides). These genera cluster in six separate lineages, suggesting that thermophiles independently evolved at least six times within the family. A list of accepted genera and species in Chaetomiaceae, together with information on their MycoBank numbers, living ex-type strains and GenBank accession numbers to ITS, LSU, rpb2 and tub2 sequences is provided. Furthermore, we provide suggestions how to describe and identify Chaetomiaceae species. Taxonomic novelties: new genera: Parvomelanocarpus X.Wei Wang & Houbraken, Pseudohumicola X.Wei Wang, P.J.

RÉSUMÉ
OBJECTIVE: To explore the relationship between sleep habits (sleep duration, sleep efficiency, sleep onset timing) and ischemic stroke, and whether there is an interaction between sleep habits and ischemic stroke susceptibility gene loci. METHODS: A questionnaire survey, physical examination, blood biochemical testing and genotyping were conducted among rural residents in Beijing, and the gene loci of ischemic stroke suggested by previous genome-wide association studies (GWAS) were screened. Multivariable generalized linear model was used to analyze the correlation between sleep habits, sleep-gene interaction and ischemic stroke. RESULTS: A total of 4 648 subjects with an average age of (58.5±8.7) years were enrolled, including 1 316 patients with ischemic stroke. Compared with non-stroke patients, stroke patients with sleep duration ≥9 hours, sleep efficiency < 80%, and sleep onset timing earlier than 22:00 accounted for a higher proportion (P < 0.05). There was no significant association between sleep duration and risk of ischemic stroke (OR=1.04, 95%CI: 0.99-1.10, P=0.085). Sleep efficiency was inversely associated with the risk of ischemic stroke (OR=0.18, 95%CI: 0.06-0.53, P=0.002). The risk of ischemic stroke in the subjects with sleep efficiency < 80% was 1.47-fold (95%CI: 1.03-2.10, P=0.033) of that in the subjects with sleep efficiency ≥80%. Falling asleep earlier than 22:00 was associated with 1.26 times greater risk of stroke than falling asleep between 22:00 and 22:59 (95%CI: 1.04-1.52, P=0.017). Multifactorial adjustment model showed that rs579459 on ABO gene had an interaction with sleep time (P for interaction =0.040). When there were two T alleles for rs579459 on the ABO gene, those who fell asleep before 22:00 had 1.56 times (95%CI: 1.20-2.04, P=0.001) the risk of stroke compared with those who fell asleep between 22:00 and 22:59, and there was no significant difference when the number of pathogenic alleles was 0 or 1. In the model adjusted only for gender, age and family structure, sleep duration and the number of T allele rs2634074 on PITX2 gene had an interaction with ischemic stroke (P for interaction=0.033). CONCLUSION: Decreased sleep efficiency is associated with increased risk of ischemic stroke, and falling asleep earlier than 22:00 is associated with higher risk of ischemic stroke. Sleep onset timing interacted with rs579459 in ABO gene and the risk of ischemic stroke. Sleep duration and PITX2 rs2634074 may have a potential interaction with ischemic stroke risk.

Objective: To explore the clinical safety and feasibility of overlapped delta-shaped anastomosis (ODA) in totally laparoscopic right hemicolectomy (TLRHC). Methods: From May 2017 to October 2019, of the 219 patients who underwent TLRHC at the Cancer Hospital, Chinese Academy of Medical Science and Peking Union Medical College, 104 cases underwent ODA (ODA group) and 115 cases underwent conventional extracorporeal anastomosis (control group) were compared the surgical outcomes, postoperative recovery, pathological outcomes and perioperative complications. Results: The length of the skin incision in the ODA group was significantly shorter than that in the control group [(5.6±0.9) cm vs. (7.1±1.7) cm, P<0.05], and the time to first flatus and first defecation after surgery in the ODA group was significantly earlier than that in the control group [(1.7±0.7) days vs. (2.0±0.7) days; (3.2±0.6) days vs. (3.3±0.7) days, P<0.05]. While the anastomosis time, operation time, intraoperative blood loss, the time of first ground activities, the number of bowel movements within 12 days after surgery, postoperative hospital stay, tumor size, the distal and proximal margins, the number of lymph node harvested and postoperative TNM stage in the ODA group did not differ from that of the control group (P>0.05). The postoperative complication rates of patients in the ODA group and the control group were 3.8% (4/104) and 4.3% (5/115), respectively, and the difference was not significant (P>0.05). Conclusion: The application of ODA technology in TLRHC can significantly shorten thelength of skin incisionand the recovery time of bowel function, and can obtain satisfactory short-term efficacy.

OBJECTIVE: To explore the incidence of ischemic stroke after the onset of type 2 diabetes, and further analyze the risk factors, so as to provide a basis for further research. METHODS: The data were obtained from the database of the Beijing Urban Employee Basic Medical Insurance Database. The study used a prospective design to describe the incidence of ischemic stroke in patients with type 2 diabetes. In our study, these patients were followed up for seven years. Multivariate Logistic regression models were used to analyze the risk factors of ischemic stroke in patients with type 2 diabetes. RESULTS: A total of 185 813 newly diagnosed type 2 diabetes patients were enrolled, with an average age of (58.5±13.2) years, and 49.0% of them were males. A total of 10 393 patients with newly diagnosed ischemic stroke occurred in 7 years, with a cumulative incidence of 5.6% and an incidence density of 8.1/1 000 person-years. Ischemic stroke occurred in all age groups in patients with type 2 diabetes. The cumulative incidence was 1.5% (95%CI: 1.3%-1.6%) in group ≤44 years old, 3.6% (95%CI: 3.4%-3.7%) in group 45-54 years old, 5.4% (95%CI: 5.2%-5.5%) in group 55-64 years old, and 9.2% (95%CI: 9.0%-9.4%) in group ≥65 years old, and the cumulative incidence increased with age (P < 0.05). Cumulative incidence rate of the males (6.8%, 95%CI: 6.7%-7.0%) was higher than the females (4.4%, 95%CI: 4.3%-4.6%). Among the patients < 80 years old, the cumulative incidence rate of the males was higher than that of the females in all the age groups. In the patients ≥80 years of age, the cumulative incidence was higher in the females (9.2%) than in the males (7.9%). Further analysis revealed that complications, such as coronary heart disease (OR=3.18, 95%CI: 2.72-3.72), heart failure (OR=1.53, 95%CI: 1.32-1.79) and kidney failure (OR=1.45, 95%CI: 1.20-1.75) were associated with ischemic stroke in the patients with type 2 diabetes. CONCLUSION: The incidence level of ischemic stroke in patients with type 2 diabetes is high. It is necessary to strengthen the management of risk factors in elderly patients, screen the complications of type 2 diabetes as early as possible, and take active preventive and control measures.

Lower lip hypoesthesia is the most common complication following osseous genioplasty. Concentrated growth factor (CGF) has recently been shown to improve neural regeneration. The aim of this study was to evaluate the effect of concentrated growth factor on neurosensory recovery after osseous genioplasty. Patients who underwent osseous genioplasty between June 2017 and February 2020 were enrolled. CGF was applied to the mental nerve on one side. The treatment side was randomized, and the other side was considered as the control. Lower lip hypoesthesia was assessed preoperatively and postoperatively (1 week, 1, 3, 6, and 9 months) using the two-point discrimination test and a 10-point visual analogue scale (self-reported paresthesia). The assessor was blinded. Twenty-six female patients completed the study. At 1 and 3 months, both the mean two-point discrimination value and mean visual analogue scale score were significantly lower in the CGF group than in the control group (P < 0.001). At 3 months, the percentage of patients with lower lip hypoesthesia in the CGF group was significantly lower than that in the control group (P < 0.001). Both groups showed resolution of lower lip hypoesthesia at 6 months. Concentrated growth factor may accelerate the recovery of long-standing sensory nerve impairment following mental osteotomy.

Objective: To examine the risk factors of hyponatremia during perioperative period for elderly hip fracture patients. Methods: Clinical data of 1 001 patients with hip fracture over 60 years old who received surgical treatment at Department of Orthopedics,Seventh Medical Center,People's Liberation Army General Hospital from January 2012 to December 2016 were retrospectively analyzed.There were 327 males and 674 females with a median age of 81 years (range: 60 to 104 years).There were 584 cases(58.34%) intertrochanteric fractures and 417 cases(41.65%) femoral neck fractures.Hyponatremia was defined as serum sodium concentration <135 mmol/L,and patients were divided into admission hyponatremia and postoperative hyponatremia according to the occurrence time of hyponatremia.Postoperative hyponatremia was divided into early postoperative hyponatremia (within 24 hours after surgery) and discharge hyponatremia (within 48 hours before discharge or death).Patients with hyponatremia can be divided into three types according to their condition changes:persistent hyponatremia,transient hyponatremia (hyponatremia on admission,but normal blood sodium after operation),and new postoperative hyponatremia (normal blood sodium on admission,hyponatremia after operation).The incidence rate,occurrence time and type of perioperative hyponatremia in elderly patients with hip fracture were analyzed,and univariate and multivariate Logistic regression analysis was used to examine the related factors of admission and postoperative hyponatremia. Results: Among 1 001 patients,126 patients (12.69%,126/1 001) had hyponatremia on admission,161 patients (16.3%,161/987) had hyponatremia after operation,140 patients (14.6%,140/960) had early postoperative hyponatremia,128 patients (14.0%,128/916) had discharge hyponatremia.Among the 916 patients with complete perioperative blood sodium concentration data,52 patients(5.7%) had persistent hyponatremia,64 patients(7.0%) had transient hyponatremia.Seventy-seven patients(8.4%) had new onset hyponatremia.Univariate analysis showed that age,male,intertrochanteric fracture of femur,white blood cell count,hemoglobin and albumin level were correlated with hyponatremia at admission (all P≤0.05). Hyponatremia at admission,dementia,and general anesthesia were associated with postoperative hyponatremia.Multivariate analysis showed that male(OR=1.788,95%CI:1.196 to 2.674,P=0.005) and white blood cell count(OR=1.116,95%CI:1.041 to 1.195,P=0.002) were independent risk factors for admission hyponatraemia,and albumin level(OR=0.932,95%CI:0.891 to 0.982,P=0.004) were protective factors, admission hyponatremia (OR=6.481,95%CI:4.125 to 10.182,P<0.01) was an independent risk factor for postoperative hyponatremia,while general anesthesia (OR=0.614,95%CI:0.383 to 0.986,P=0.044) was a protective factor. Conclusions: The incidence of hyponatremia in elderly hip fracture patients is high.Male and high level of white blood cell counts are independent risk factors for admission hyponatremia.High level of albumin is a protective factor for admission hyponatremia.Admission hyponatremia is an independent risk factor for postoperative hyponatremia,and general anesthesia is a protective factor for postoperative hyponatremia.

Objectives: To investigate the proportion of MSM among males over 15 years old and analyze its related factors to provide a reference for estimation of MSM size. Methods: Using cross-sectional survey design, multi-stage sampling method, and street interception survey method, a survey was conducted on males over 15 years old in Kunming from October to December 2019, with an estimated sample size of 9 908. Results: Totally, 10 707 males were recruited from 30 sites in 5 counties, and 10 283 were effectively surveyed with a response rate of 96.0%. Respondents aged 16 to 40 accounted for 75.3% (7 748), senior high school or above 71.1% (7 312), and unmarried 49.8% (5 121). The proportion of homosexual behavior in the past half-year was 1.06% (95%CI: 0.86%-1.26%), and the age-adjusted rate was 0.97% (95%CI: 0.78%-1.16%). And multivariate logistic regression showed the associated factors for homosexual behavior as following: proportion of main urban area was 2.217 times (95%CI:1.004-4.895) that of the outer suburbs, registered residence outside Kunming was 0.421 times (95%CI:0.260-0.682) that of in Kunming, having been in Kunming ≤6 months was 2.282 times (95%CI:1.262-4.126) that of >6 months, senior middle school or above was 0.336 times (95%CI:0.228-0.495) that of junior middle school and below, and being married was 0.462 times (95%CI:0.303-0.705) that of unmarried. Conclusions: The proportion of over 15-year-old males who have recently practiced male-male behavior was close to 1.00% in Kunming. The relevant factors included survey areas with a permanent residency of Kumming, short-time residency, education level, and marital status. This study obtained the data and related factors, which provided a reference for estimating MSM size in Yunnan province.

Objective: To investigate the emergency management process of ruptured abdominal aortic aneurysm (RAAA), and analyze the perioperative mortality factors of different surgical methods. Methods: The emergency data and hospitalization data of 91 patients with ruptured abdominal aortic aneurysm in Xiangya Hospital of Central South University from June 2010 to June 2019 were retrospectively analyzed.Twelve of the patients died preoperatively due to excessive blood loss, and the remaining 79 patients were hospitalized for open surgery (OSR) or endovascular repair (EVAR).The differences in age, time to hospital arrival, emergency preparation time, first creatinine value, emergency infusion volume, preoperative drop in blood pressure, preoperative use of vasoactive drugs and iliac artery involvement were compared between preoperative death group (n=12) and preoperative survival group (n=79), OSR group (n=50) and EVAR group (n=29), postoperative death group (n=23) and postoperative survival group (n=56). Results: Seventy-nine patients received open surgery or endovascular repair, and 23 died after operation. Age, time to hospital arrival, first creatinine value and emergency infusion volume were (77±11) years, (18±5)h, (469±150) µmol/L, (4 140±1 743) ml in the preoperative death group and (70±10) years, (12±8) h, (228±174) µmol/L, (1 358±1 211) ml in the preoperative survival group, respectively, and the differences were statistically significant (all P<0.05). There were no significant differences in preoperative data, intraoperative treatment and postoperative perioperative mortality between the open surgery group and the endovascular repair group (all P>0.05). The intraoperative blood loss, operation time and aortic occlusion rate in the endovascular repair group were 100 (50, 175) ml, (3.2±0.9) h, 13.8%, respectively, which were better than that in the open surgery group 1700 (600, 3425) ml, (5.2±1.1) h, 100%. The differences were statistically significant (all P<0.05). Age, emergency preparation time, first creatinine value, emergency infusion volume, blood pressure decline rate and vasoactive drug utilization rate in the death group were (77±8) years, (4.1±1.7) h, (456±172) µmol/L, (2 024±1 687) ml, 100%, 100%, respectively, and (68±10) years, (2.7±2.2) h, (135±26) µmol/L, (1 085±825) ml, 21.4%, 12.5% in the survival group, respectively. The differences were statistically significant (all P<0.05). Conclusions: Age, emergency preparation time, first creatinine value, emergency infusion volume, decreased blood pressure and use of vasoactive drugs are all associated with perioperative death in patients with ruptured abdominal aortic aneurysm. EVAR surgery is a better choice if conditions exist.
