Objective:To investigate the mechanism of liver and lung injury in mouse septic models.Methods:Twenty-four male Kunming mice were subjected to cecal ligation and puncture(CLP)or sham operation.The permeability of microvasculature,water contents,activities of myeloperoxidase(MPO)and the apoptosis of microvascular endothelial cells in lung microvasculature and liver sinus were examined 3 h and 12 h after operation.Results:Both the liver and lung showed a significant increase in microvessel permeability at 12 h in CLP group compared with sham operation group.MPO activity and water content in CLP group were obviously higher than those in the sham operation group.The apoptosis of lung microvascular endothelial cells at 12 h in CLP group(5.03?0.92)% was significantly higher than that of control group(3.48?1.21)%(P

Background: Sentinel lymph node (SLN) mapping has been recommended as an alternative staging approach to lymphadenectomy for apparent uterine-confined endometrial cancer (EC). However, the prognostic value of SLN mapping alone instead of systematic lymphadenectomy on EC patients remains unclear. Methods A multi-center, open label, non-inferiority randomized controlled trial has been designed to identify if SLN mapping alone is not inferior to pelvic lymphadenectomy on prognosis of patients with intermediate-high-risk EC clinically confined to uterus. Eligible patients will be 1:1 randomly assigned to accept SLN mapping or pelvic lymphadenectomy. The primary endpoint is the 2-year progression-free survival (PFS). The second points are the 5-year PFS, 5-year overall survival, surgery-related adverse events and life quality. A total of 780 patients will be enrolled from 6 hospitals in China within 3-year period and followed up for 5 years.

Objective To evaluate the effect of the bird exercises of Wuqinxi bird exercises combined with simple breath exercises on the quality of life and immune function in patients with chronic obstructive pulmonary disease (COPD). Methods Sixty-eight COPD patients were allocated into observation group (N=32) and control group (N=36)according to the intention of the patients. The control group was given conventional inhalation of Seretide and Tiotropium Bromide,and the observation group did Wuqinxi bird exercises and simple breath exercises plus the conventional inhalation therapy. Before and after treatment,we compared the BODE indexes such as body mass index (BMI), air flow obstruction index of forced expiratory volume in one second (FEV1%), dyspnea scores,exercise capacity (6-min walking distance)as well as COPD assessment test (CAT)scores between the two groups before and after treatment. Meanwhile, the changes of T lymphocyte subtype CD3, CD4, CD8, CD4/CD8 levels and serum immunoglobulin M (IgM),IgA,IgG levels were also monitored. Results(1)After intervention, dyspnea scores of the observation group were obviously improved (P < 0.01), while the control group showed no obvious changes in dyspnea scores (P > 0.05). The observation group had better effect on improving dyspnea scores and 6-min walking distance than the control group (P < 0.05 or P <0.01).(2)After intervention,BODE index and CAT scores were improved in the observation group(P<0.01),BODE index was improved in the control group (P < 0.05), and the improvement of BODE index and CAT scores in the observation group was superior to that in the control group (P < 0.05 or P < 0.01). (3)After intervention, T lymphocyte subtype CD3 and CD4 levels as well as the serum IgM, IgA, IgG levels in the observation group were increased (P < 0.05 or P < 0.01),and IgA level in the control group was also increased (P < 0.05). The observation group had stronger effect on increasing T lymphocyte subtype CD3 and CD4 levels than the control group(P < 0.05 or P < 0.01).(4)The difference of adverse reaction incidence was insignificant between the two groups (P > 0.05). Conclusion Application of Wuqinxi bird exercises and simple breath exercises based on conventional inhalation therapy is effective on improving dyspnea, 6-min walking distance, BODE index and CAT scores, and on increasing T lymphocyte subtype CD3 and CD4 levels as well as the serum IgM and IgG levels of COPD patients.

Objective To evaluate the long-term effects and analyze causes of non-response to cardiac resynchronization therapy (CRT) in heart failure (HF) patients with permanent atrial fibrillation (AF).Methods Thirty-three patients with HF and AF [29 men,mean age (61 ± 10) years,NYHA class Ⅲ or IV,left ventricular ejection fraction(LVEF) ≤35％,QRS ≥ 120 ms in 31 cases] underwent biventricular pacing ( n =26 ) or bi-ventricular pacing and atrioventricular node ablation ( AVN-ablation,n =7 ) were included in this study.Non-response was defined:the increase of left ventricular ejection fraction (LVEF) was less than 15％.Patients were followed-up for 4 years.Results Six patients died during follow up.Non-responder to CRT was observed in 6 out of 27 survived patients (22.22％).Six out of 7 patients underwent AVN-ablation were in responder group and 1 in non-responder group.Comparing with responder group,the baseline LVEF was significantly higher (37％ vs.32％,P =0.003),and the history of HF was significantly longer ( 6.3 years vs.4.1 years,P =0.039 ),pulmonary artery pressure was significantly higher (53 vs.32 mm Hg,P =0.027),bi-ventricular pacing percentage ( BIVP％ ) was significantly lower (75.86％ vs.91.73％,P =0.007) in non-responder group.Conclusions Higher LVEF,longer HF history,higher pulmonary artery pressure and lower BIVP％ are factors linked with non-responses to CRT in this patient cohort.CRT plus AVN-ablation is associated with high response rate to CRT in this patient cohort.

Cysticercosis refers to a parasitic infection caused by the larvae of pork tapeworm Taenia solium.It is a parasitic zoonosis and listed by the World Health Organization(WHO)as one of the neglected tropical diseases.Cysticercosis is spread-ing all over the world through globalization and it mainly epidemic in developing countries.In the southwest and minority nation-ality areas of China,as a result of the low level of medical and health care,and the unchangeable diet custom,there are still many cases of cysticercosis,which is manifested as a local high prevalence.Neuroimaging is the preferred method for cysticerco-sis diagnosis,and by using CT and MRI scans it is possible to visualise the infecting cysticerci and assess their number and loca-tion within the central nervous system(CNS).The immunological assay is also required in the diagnosis.At present,the preven-tion and control of cysticercosis is still relatively weak.In this paper,the current status and research progress of cysticercosis are reviewed,and further suggestions on the prevention and control of cysticercosis are put forward.

This study attempts to develop a reference substance for the live bacteria count of Streptococcicosis live vaccines in order to evaluate the validity of live bacterial count in inspection and testing. We prepared a batch of live Streptococcus suis reference substance for live bacterial count, tested their physical property, purity, vacuum degree, remaining moisture, and determined their homogeneity, thermal stability and transportation stability. Moreover, we organized collaborative calibration to assign count values to the reference substance and determine the shelf life of the reference substance in 12 months. The results showed that the physical property, the purity, the remaining moisture and the vacuum degree of the reference substance were all in compliance with the requirements of the Chinese Veterinary Pharmacopoeia. The homogeneity test showed that the coefficient of variation of the count of the reference substance was less than 10%, indicating a good homogeneity. Transportation stability test showed that the reference substance remained active after 72 h transportation in summer and winter with the package of styrofoam boxes and ice packs. Thermal stability test showed that the reference substance could be stored for up to 3 months at -20 °C, or up to 21 days at 4 °C. According to the collaborative calibration, the reference vaccine was assigned a count value range of (8.5-12.1)×107 CFU/ampoule. The shelf life test showed that the reference substance was stable for 12 months when stored at -70 °C. The reference substance could provide a reference for the live bacterial count of Streptococcicosis live vaccines. Moreover, it could also be used as a reference to evaluate the quality of corresponding agar media.

Objective: To analyze the influencing factors of healthy life expectancy (HLE). Methods: Seven Chinese and English databases were used for the retrieval of related literatures published by May 7, 2022 to identify influencing factors of HLE, including diseases and injuries and their risk factors. Based on the ecological model of health determinants, this study classifies the risk factors of diseases and injuries into five levels: personal characteristics, individual behavior and lifestyle, social network, living and working conditions, and macroscopic socio-economic, cultural and environmental conditions. Contents of research area, HLE indicators, research population, influencing factors, data sources and results were extracted. The frequencies of reported documents of different HLE indicators and influencing factors of different dimensions were visualized by using evidence map, and the empirical studies of four authoritative English medical journals and Chinese core medical journals were further compared and described. Results: A total of 90 studies were selected, in which 26 were conducted in China (28.9%). Fifty-three studies are about diseases and injuries in the first dimension, and all of them have studied non-communicable diseases, accounting for the highest proportion (58.9%). There were 77 studies about the analysis on the determinants of health at five levels by an ecological model, all the studies reported multi-level results. Among them, 53 studies reported personal characteristics (58.9%), 47 studies reported individual behavior and lifestyle (52.2%), 10 studies reported social networks (11.1%), 35 studies reported living and working environment (38.9%), 8 studies reported social economy, culture status and environment condition (8.9%). The literatures about HLE published by 4 authoritative English medical journals and 21 Chinese core medical journals in recent three years were selected. Non-communicable diseases and personal characteristics were the top two most commonly studied factors of HLE, and 11 (52.3%) and 12 (57.1%) studies reported these two kinds of factors respectively. The most important factor contributing to the global disability-adjusted life years of non-communicable diseases was individual behavior and lifestyle, which was the most changeable factor. Conclusions: In recent three years, studies involving influencing factors of HLE were mainly non-communicable diseases and personal characteristics. In the future, individual behavior, lifestyle and working environment should be strengthened.

Objective: To explore the promotion effect of laparoscopic standardized surgery for gastric cancer observational in some regional medical centers in Shanghai. Methods: A retrospective cohort study was carried out. Eleven regional medical centers in Shanghai received the promotion program of laparoscopic standardized surgery for gastric cancer, which was led by Ruijin Hospital, Shanghai Jiaotong University School of Medicine (Shanghai Minimally Invasive Surgery Center) from January to December 2020. Clinicopathological data of gastric cancer patients treated at these 11 regional medical centers before and after the promotion program were collected. Inclusion criteria were as follows: patients undergoing laparoscopic distal gastrectomy or total gastrectomy; gastric cancer confirmed by pathology; without distant metastasis or peritoneal metastasis. Patients who did not undergo laparoscopic D2 radical resection, or received neoadjuvant chemotherapy before surgery, or without complete clinical data were excluded. Patients undergoing laparoscopic surgery from January to December 2019 were included in the pre-promotion group (46 cases). Patients undergoing laparoscopic surgery from January to December 2021 were included in the post-promotion group (102 cases). In addition, patients undergoing laparoscopic surgery at Ruijin Hospital from January 2021 to December were included in the control group (138 cases). The baseline data, perioperative measurements postoperative complications, and pathological results of the three groups were analyzed and compared. Results: There were no significant differences in baseline characteristics among the three groups (all P>0.05). Compared with the pre-promotion group, the operation time in post-promotion group was significantly shorter [(207.3±36.0) minutes vs. (254.2±47.1) minutes, t=7.038,P<0.001], and the number of harvested lymph node was significantly more (24.4±12.2 vs. 18.9±5.5, t=2.900, P=0.004). However, there were no significant differences in the extent of resection, time to fluid intake, and postoperative hospital stay between the two groups (all P>0.05). Compared with the control group, the operation time [(207.3±36.0) minutes vs (172.6±26.0) minutes, t=8.281, P<0.001], time to fluid intake [(6.3±3.2) days than (5.5±3.0) days, t=2.029, P=0.044], and the postoperative hospital stay [(14.3±5.6) days vs. (10.1±4.8) days, t=6.036, P<0.001] in the post- promotion group were still longer. Total gastrectomy was less common in the post-promotion group compared with the control group [18 cases (17.6%) vs. 41 cases (29.7%), χ²=7.380, P=0.007]. However, there was no significant difference in the number of harvested lymph node between the two groups (P>0.05). The morbidity of postoperative complication in the post-promotion group (9.8%, 10/102) was significantly lower than that in the pre-promotion group (23.9%, 11/46) (χ²=5.183, P=0.023), while above morbidity was not significantly different between the post-promotion group and the control group [9.8% vs. 6.5% (9/138), χ²=0.867, P=0.352]. Conclusion: After the promotion of laparoscopic standardized surgery for gastric cancer in regional medical centers, the standardization degree of surgery has been improved, and the morbidity of postoperative complication decreases. Laparoscopic standardized surgery for gastric cancer can be promoted to more regional medical centers.
