Objective: To grasp the distribution characteristics and incidence trend of varicella in Shaanxi Province, so as to provide a reference for scientific and accurate prevention and control strategies. Methods: Data of 161 377 varicella cases in Shaanxi Province from 2016 to 2023 were collected and described from Surveillance Report Management System, a subsystem of National Disease Control and Prevention Information Systems of Chinese Center for Disease Control and Prevention. FlexScan 3.1.2 software was used to determine irregular spatial clustering, and spatial clustering area was detected for each year. Results: The incidence of varicella in Shaanxi Province showed a seasonal bimodal distribution with peaks from April to July (36.68%) and from October to next January (48.07%). The cases were mainly concentrated in the 3-12 years old group (60.50%), and there was a trend of high incidence age shift within the 0-19 age group from 2021. Most of the cases were students (62.40%) and preschool children ( 17.78 %). The outbreaks mainly occurred in primary schools (76.47%). The regional distribution was mainly concentrated in some areas of southern Shaanxi and Guanzhong. Through spatial analysis, the primary clusters were primarily concentrated in Ankang and Hanzhong cities in southern Shaanxi from 2016 to 2023, and the secondary clusters were mainly found in some areas of Guanzhong (Xi an, Baoji and Weinan cities). Conclusions Prevention and control of varicella should be focused on students and kindergartens aged 3-12 years in southern and Guanzhong areas of Shaanxi Province. Continuous varicella surveillance and vaccination measures should be carried out, and the two dose vaccination strategy and intensive vaccination of key groups should be actively promoted.

Objective To explore the application effect of blood pressure management based on the health belief model in patients with moyamoya disease after cerebral vascular reconstruction sur-gery.Methods From February to July 2024,210 patients with moyamoya disease who underwent cerebral vascular reconstruction surgery in our hospital were selected as study subjects.They were randomly divided into control group and intervention group,with 105 cases in each group.The control group received routine nursing care,while the intervention group applied blood pressure management based on the health belief model on the basis of routine nursing care.The postoperative cerebral hy-perperfusion syndrome and blood pressure control status of the two groups were compared,and the Health Belief Scale and the Mishel Uncertainty in Illness Scale were used to evaluate the effects before and after intervention.Results A total of 203 patients completed the study,including 100 cases in the control group and 103 cases in the intervention group.There were statistically significant differ-ences in the incidence of cerebral hyperperfusion syndrome and the proportion of patients with blood pressure higher than baseline data between the two groups(P＜0.05).After the intervention,there were statistically significant differences in the postoperative cerebral hyperperfusion syndrome status and blood pressure control status between the two groups(P＜0.05).After intervention,there were statistically significant differences in the scores of susceptibility and health motivation dimensions as well as the total score in the Health Belief Scale between the intervention group and the control group(P＜0.05).After the intervention,there were statistically significant differences in the scores of ambiguity and unpredictability dimensions as well as the total score in the Mishel Uncertainty in Ill-ness Scale between the intervention group and the control group(P＜0.05).Conclusion Blood pressure management based on the health belief model can effectively control blood pressure,reduce the incidence of cerebral hyperperfusion,improve health beliefs,and reduce the sense of uncertainty about the disease.

Objective:To analyze the early diagnostic value of plasma soluble cluster of differentiation 14 subtype (sCD14-ST, Presepsin) in sepsis in a population with suspected sepsis in fever clinic.Methods:A prospective observational study was conducted. The patients admitted to the fever clinic of Beijing Chaoyang Hospital from April to December 2022 were enrolled as the study objects. According to sequential organ failure assessment (SOFA) score, the patients were divided into low SOFA score group (SOFA score ≤3) and high SOFA score group (SOFA score > 3). Venous blood was collected at the time of admission. The level of plasma Presepsin was detected by chemiluminescence enzyme-linked immunoassay. The level of plasma procalcitonin (PCT) was detected by enzyme-linked immunofluorescence method. The level of C-reactive protein (CRP) was detected by scattering turbidimetry. White blood cell count (WBC) and neutrophil count (NEUT) were measured by automatic blood cell analyzer. For patients with fear of cold or chills, venous blood of upper limbs was taken for blood culture at the time of admission. The differences in inflammatory biomarkers were compared between the two groups. Binary multivariate Logistic regression analysis was used to screen the early risk factors of sepsis in fever outpatients with suspected sepsis. Receiver operator characteristic curve (ROC curve) was drawn to investigate the early diagnostic value of Presepsin and other inflammatory markers in sepsis, and to analyze the optimal cut-off value.Results:A total of 149 fever outpatients with suspected sepsis were enrolled, including 92 patients with low SOFA score and 57 patients with high SOFA score. Plasma PCT and Presepsin levels in the high SOFA score group were significantly higher than those in the low SOFA score group [PCT (μg/L): 0.77 (0.18, 2.02) vs. 0.22 (0.09, 0.71), Presepsin (ng/L): 1?129.00 (785.50, 1?766.50) vs. 563.00 (460.50, 772.25), both P < 0.01]. There was no significant difference in WBC, NEUT, CRP or positive rate of blood culture between the high and low SOFA score groups [WBC (×10 9/L): 11.32±5.47 vs. 11.14±5.29, NEUT (×10 9/L): 9.88±4.89 vs. 9.60±5.10, CRP (mg/L): 54.05 (15.95, 128.90) vs. 46.11 (19.60, 104.60), blood culture positivity rate: 42.3% (11/26) vs. 29.4% (10/34), all P > 0.05]. Multivariate Logistic regression analysis showed that Presepsin was an early risk factor for sepsis in suspected sepsis patients in fever clinics [odds ratio ( OR) = 16.96, 95% confidence interval (95% CI) was 6.35-45.29, P = 0.000]. ROC curve analysis showed that the early diagnostic value of Presepsin in sepsis was significantly better than WBC, NEUT, CRP, PCT, and blood culture [the area under the ROC curve (AUC) and 95% CI: 0.832 (0.771-0.899) vs. 0.522 (0.424-0.619), 0.532 (0.435-0.629), 0.533 (0.435-0.632), 0.664 (0.574-0.753), 0.554 (0.458-0.650)]. When the optimal cut-off value of Presepsin was 646.50 ng/L, its sensitivity and positive predictive value were higher than those of WBC, NEUT, CRP, and PCT (sensitivity: 89.5% vs. 38.6%, 68.4%, 38.6%, 57.9%; positive predictive value: 64.6% vs. 44.9%, 44.3%, 47.8%, 55.9%). Conclusion:Plasma PCT and Presepsin have early diagnostic value for sepsis in suspected sepsis patients in fever clinics, and Presepsin is more sensitive than PCT and can be used as a early marker of sepsis.

Based on promoting the " sports and health integration" and with the aim of the positive role of traditional sports in promoting public health in an all-round and whole-cycle way, this paper uses the literature research method to explore the connotation of traditional sports in ancient Chinese books and literatures, such as " treating no diseases" , " treating mild diseases" , " treating desired diseases" and " treating existing diseases" . The traditional exercise prescription is interpreted from the modern language such as the amount of exercise and intensity, application time, role, standardization and matters needing attention, so as to provide the theoretical basis for the integration of traditional exercise prescription into grassroots health management by providing exercise promotion services for healthy, sub-healthy, sick and rehabilitated people.

Objective:To observe the effect of Ba Duan Jin(Eight-brocade Exercise)plus Tuina(Chinese therapeutic massage)in treating primary dysmenorrhea due to cold-induced blood stasis in female college students and on the score of fatigue scale-14(FS-14). Methods:Seventy-two female college students with primary dysmenorrhea due to cold-induced blood stasis were randomized into a Tuina group and a joint group,with 36 cases in each group.The Tuina group only received Tuina manipulations.In the joint group,besides the same Tuina manipulations,patients practiced Ba Duan Jin.For both groups,the once-daily intervention was conducted from 6 d before the menstrual period until menstrual day 1 for 3 menstrual cycles.Changes in the scores of COX menstrual symptom scale(CMSS),visual analog scale(VAS),and FS-14 after the intervention were observed.Clinical efficacy was also estimated. Results:During the process,1 case dropped out in the Tuina group,and 35 cases completed the intervention;2 cases dropped out in the joint group,and 34 cases completed the intervention.The total effective rate was 94.1%in the joint group,higher than 88.6%in the Tuina group(P<0.05).After treatment,the symptom duration and intensity scores in the scores of CMSS,VAS,and FS-14 declined in both groups(P<0.05 or P<0.01);the CMSS symptom duration score and FS-14 score were lower in the joint group than in the Tuina group(P<0.05). Conclusion:Tuina manipulations alone or combined with Ba Duan Jin practice can effectively treat primary dysmenorrhea due to cold-induced blood stasis in female college students;when combined with Ba Duan Jin practice,Tuina manipulations can more significantly improve pain duration and fatigue,suggesting the advantages of combining Tuina Gongfa and manipulations.

A series of new monobactam sulfonates is continuously synthesized and evaluated for their antimicrobial efficacies against Gram-negative bacteria. Compound 33a (IMBZ18G) is highly effective in vitro and in vivo against clinically intractable multi-drug-resistant (MDR) Gram-negative strains, with a highly druglike nature. The checkerboard assay reveals its significant synergistic effect with β-lactamase inhibitor avibactam, and the MIC values against MDR enterobacteria were reduced up to 4-512 folds. X-ray co-crystal and chemoproteomic assays indicate that the anti-MDR bacteria effect of 33a results from the dual inhibition of the common PBP3 and some class A and C β-lactamases. Accordingly, preclinical studies of 33a alone and 33a‒avibactam combination as potential innovative candidates are actively going on, in the treatment of β-lactamase-producing MDR Gram-negative bacterial infections.

Objective:To investigate the relationship between dietary vitamin A intake and its sources in the first trimester and gestational diabetes mellitus (GDM).Methods:A prospective study was conducted to select women at 6-14 weeks of gestation in an obstetric clinic of a maternal and child health care medical institution in Chengdu in 2017. The types and quantities of food during the first trimester were collected by 3-day 24-hour dietary recalls. Dietary vitamin A intake was calculated based on the Chinese Food Composition Table (2018), and it was divided into animal and plant vitamin A intakes according to its food sources. An oral glucose tolerance test was performed at 24-28 weeks of gestation to diagnose GDM according to the Chinese guidelines for diagnosis and treatment of gestational diabetes mellitus (2014). According to the estimated average requirement (EAR) and recommended nutrient intake (RNI), dietary vitamin A intake was divided into low-level group (RNI). Animal and plant vitamin A intakes were divided into four groups (Q1-Q4) according to the quartile method, respectively. The association between dietary vitamin A intake, its different sources of vitamin A intake and GDM in the first trimester was analyzed by log-binomial regression models.Results:A total of 1 298 valid samples were finally included. The average dietary vitamin A intake, animal and plant vitamin A intakes in the first trimester were 341.1 (227.8-501.0) μgRAE/d, 139.3 (69.6-195.3) μgRAE/d and 184.2 (99.4-301.1) μgRAE/d, respectively. After adjusting for confounding factors, log-binomial regression analysis showed that the risk of GDM in high-level group of dietary vitamin A intake was lower than that in low-level group [ RR (95% CI):0.53 (0.36-0.80)]. Pregnant women in the highest quartile of animal vitamin A intake had a lower risk of GDM than those in the lowest quartile [ RR (95% CI):0.66 (0.47-0.95)]. No relationship between plant vitamin A intake and GDM was found. Conclusion:Dietary vitamin A intake in the first trimester is associated with the occurrence of GDM, and higher intake than RNI may reduce the risk of GDM. Higher vitamin A intake from animal-derived food is associated with decreased risk of GDM.

Objective:To explore the effects of dietary glycemic load (GL) during first trimester on the risk of gestational diabetes mellitus (GDM).Methods:A prospective study was conducted among healthy women with singleton pregnancy at 8-14 weeks of gestation in a maternity out-patient clinic of maternal-and-child health care institution in Chengdu, Sichuan province. Information on dietary intake during the first trimester was collected through a 3-day 24-hour dietary recall. Glycemic index (GI) values were obtained from China Food Composition Tables (Standard Edition) and International Tables of Glycemic Index and Glycemic Load Values (2008). Dietary GL and GLs of staple foods were calculated based on GI values and the amount of carbohydrate consumed per day. Diagnostic criteria of GDM was followed the Guidelines for Diagnosis and Treatment of Pregnancy Diabetes in China (2014), and used on participants who underwent an oral glucose tolerant test during 24-28 weeks of gestation. Log-binomial regression models were used to explore the associations between both quartiles of dietary GL, GLs of staple foods and the risks of GDM,respectively.Results:The medians of dietary GL and GL of staple foods were 145.70 (113.23-180.85) and 121.05 (89.08-155.70), respectively. The median GL of both rice and tubers were 73.14 (43.89-107.50) and 3.43 (0.00-9.84), respectively. After adjusting for the age at pregnancy, pre-pregnancy body mass index and other confounding factors, results of log-binomial regressions analysis showed that when compared with the lowest quartile of dietary GL group, the third and highest quartiles of dietary GL groups increased the risk of GDM ( RR=1.47, 95% CI: 1.20-1.80; RR=1.31, 95% CI: 1.04-1.64), respectively. Compared with the lowest quartile of GL of staple foods, the third and highest quartiles of GL of staple foods groups also increased the risk of GDM ( RR=1.28, 95% CI: 1.04-1.58; RR=1.27, 95% CI: 1.02-1.60), respectively. The third and highest quartiles of GL of rice groups increased the risk of GDM ( RR=1.30, 95% CI: 1.06-1.59; RR=1.28, 95% CI: 1.03-1.59), respectively, than the lowest quartile of GL of rice group. When compared with the lowest quartile of GL of tubers group, the highest quartile of GL of tubers group increased the risk of GDM ( RR=1.30, 95% CI: 1.09-1.54). However, we did not notice the effects of wheat GL and coarse grain GL on the risk of GDM. Conclusions:A positive association was found between dietary glycemic load and the risk of GDM. Higher dietary glycemic load, especially in rice and tubers during first trimester, seemed to have increased the risk of GDM.

Objective: To investigate the surgical options for splenic lymph node dissection in patients with advanced gastric cancer undergoing radical total gastrectomy, and to evaluate the sentinel effect of No. 4s lymph node on splenic lymph node metastasis. Methods: A prospective, single-center, randomized and controlled study was carried out (Trial registration, No.NCT02980861). Enrollment criteria: (1) >18 years old and <65 years old; (2) gastric adenocarcinoma locating in the proximal or corpus; (3) preoperative clinical staging as cT2-4aN0-3M0; (4) D2 radical total gastrectomy feasible judged before operation; (5) physical ability score 0 to 1; (6) I to III of ASA classification. Pregnant or lactating women, patients with severe mental illness or previous history of upper abdominal surgery, those suffered from other malignant tumors in the past 5 years, or heart and lung system diseases judged to affect surgery before operation, those receiving preoperative chemotherapy, radiotherapy or targeted therapies, and distant metastases being found during surgery were excluded. According to above criteria, 222 patients at The First Medical Center of Chinese PLA General Hospital from December 2016 to December 2017 were enrolled prospectively and were randomly divided into the laparoscopic splenic hilar lymph node dissection group (laparoscopic group, n=114) and the open splenic hilar lymph node dissection group (open group, n=108). The result of rapid frozen immunohistochemistry of harvested No.4s lymph nodes was used to evaluate the sensitivity and specificity of sentinel effect on splenic hilar lymph node metastasis. The surgical parameters, postoperative recovery parameters, and complication rates were compared between the two groups. Results: There were 80 males and 34 females in the lapascopic group with a mean age of (56.1±10.2) years, and 69 males and 39 females in the open group with a mean age of (58.4±10.9) years. There were no significant differences in baseline data between the two groups (all P>0.05). Total blood loss was less in the laparoscopic group [(96.3±82.4) ml vs. (116.6±101.9) ml, t=1.124, P<0.001], and the amount of bleeding from the splenic hilar lymph nodes dissected was also less than that in the open group [(25.3±17.8) ml vs. (59.5±36.4) ml, t=1.172, P<0.001]. However, the operation time, the time of splenic hilar lymph node, the number of lymph node dissected and number of splenic hilar lymph node dissected were not significantly different between the two groups (all P>0.05). As compared to the open group, the laparoscopic group had shorter time to the first flatus [(1.3±1.2) days vs. (1.6±1.5) days, t=1.665, P=0.021], shorter time to fluid diet [(4.6±1.4) days vs. (4.9 ± 1.6) days, t=1.436, P=0.007], shorter time to remove nasogastric tube [(3.9±2.6) days vs. (4.3±2.4) days, t=0.687, P<0.001] and shorter hospital stay [(10.3±6.6) days vs. (12.1±7.2) days, t=0.697, P<0.001]. Complication rate was 14.0% (16/114) and _12.0% (₁3/108) in the laparoscopic group and the open group, respectively, without significant difference (χ²=6.723, P=0.331). The sensitivity of the No. 4s lymph node for the prediction of splenic hilar lymph node metastasis reached 89.5%, and the specificity reached 99.6%. Conclusions Laparoscopic technique is safe and feasible in the treatment of splenic hilar lymph node dissection in advanced gastric cancer. The No.4s lymph node examination has good sentinel effect on predicting the metastasis of splenic hilar lymph nodes.
