Objective: To investigate the spatio-temporal clustering characteristics of pulmonary tuberculosis (PTB) aged 60 years and above in Shaoxing City from 2019 to 2023, so as to provide insights into prevention and control of PTB among the elderly. Methods: Data of PTB cases aged 60 years and above in Shaoxing City from 2019 to 2023 were collected from Tuberculosis Management Information System of Chinese Disease Prevention and Control Information System. The population data were collected from Shaoxing Statistical Yearbook. Vector map information was collected from Shaoxing Geographic Information Public Service Platform. The spatio-temporal clustering characteristics of PTB cases aged 60 years and above were analyzed using global spatial autocorrelation, local spatial autocorrelation and spatio-temporal scanning. Results: Totally 3 722 PTB cases aged 60 years and above were registered in Shaoxing City. The average annual registration rate was 61.71/105, showing no significant trend (P>0.05). Totally 2 548 pathogenetically positive cases were registered, with an average annual registration rate of 42.25/105. Spatial autocorrelation analysis showed there was a positive spatial correlation of PTB in 2019 and 2021 (both Moran's I>0, both P<0.05). Shengzhou City showed a high-low clustering, and Keqiao District and Shangyu District showed a low-low clustering. Spatio-temporal scanning analysis showed that a class Ⅰ cluster was located in Shengzhou City, with aggregation time from March 1, 2019 to August 31, 2021. The class Ⅱ clusters were located in Zhuji City, Shangyu City and Keqiao District, with aggregation time from March 1, 2021 to August 31, 2023, from April 1, 2021 to September 30, 2023, and from June 1, 2021 to November 30, 2023, respectively. Conclusion The PTB cases aged 60 years and above in Shaoxing City from 2019 to 2023 mainly concentrated in Shengzhou City, where the prevention and control of PTB among the elderly should be strengthened.

Objective To evaluate the feasibility and safety of double-lumen balloon catheter applied in patients with achalasia of cricopharyngeal muscle. Method Fifty patients with achalasia of cricopharyngeal muscle were randomly divided into experimental group and control group. All the patients received routine drug treatment,swallowing function training,feeding training and low frequency VitalStim electric stimulation. In addition,double-lumen balloon catheter and #14 urinary catheters were applied to patients in the experimental group and control group,respectively. The swallow water tests and video fluoroscopy swallowing study(VFSS) were used to evaluate the treatment effects,the electron-nasopharyngolaryngoscope was used to assess bleeding and swelling of mucous membrane,and VRS-5 was used to assess pain. Result After treatment,the scores of swallow water tests and VFSS were significantly better than those before treatment in both groups(P<0.05). There was no significant difference between the two groups(P>0.05). However,the incidence of complications was significantly higher in the control group than that of experimental group(P<0.05). Conclusion Both treatment methods can effectively relieve the achalasia of cricopharyngeal muscle,but modified double-lumen balloon catheter can reduce the incidence of complications.

Objective To compare the anesthetic effect of sufentanil combined with propofol and remifentanil combined with propofol in hysteroscopic surgery, and to provide a scientific basis for the selection of clinical anesthesia methods. Methods From November 2016 to March 2017, 94 patients in Lishui central hospital underwent hysteroscopic surgery were divided into the observation group and the control group according the anesthesia way, 47 cases in each group. The control group were given remifentanil(1 μg/kg) combined with propofol(2 mg/kg) by intravenous injection, the observation group were given sufentanil(0.2 μg/kg) combined with propofol(2 mg/kg). The mean arterial pressure(MAP), respiration (RR), pulse oxygen saturation (SpO2), heart rate (HR), the onset time of anesthesia, the postoperative recovery time, the recovery time of orientation and Ramsay sedation score in the two groups were recorded and compared before anesthesia, 2 min after anesthesia, 10 min after operation, 10min after operation finished.

The onset time of anesthesia, postoperative recovery time, orientation recovery time, Ramsay score difference between the groups was not statistically significant sedation score difference was statistically significant between group VAS, observation group than in the control group (P<0.05). Conclusion Sufentanil combined with propofol anesthesia were used in hysteroscopic surgery, which can better maintain the vital signs of patients, effectively reduce postoperative pain.

Objective To investigate the relationship between leptin level of IGR patients and intima-media thickness (IMT) of carotid arterial. Methods One hundred and eighteen IGR patents were enrolled into the following three groups according to the result of oral glucose tolerance test (OGTT): 38 cases of the purely impaired fasting glucose (IFG) group, 42 cases of the purely impaired glucose tolerance (IGT) group and 42 cases of the IFG combining with IGT (IFG + IGT) group. Thirty-eight cases with normol glucose tolerance (NGR) were enrolled in the NGR group. The blood fat, fasting blood-glucose (FBG), fasting insulin (insulin), fasting C peptide , 2 h-postprandial blood glucose , 2 h-insulin , 2 h-C peptide , glycosylated hemoglobin (HbA1C), C-reactive protein (CRP), body mass index (BMI), leptin and IMT were determined in patients of the three groups and the healthy controls. The multiple linear regression was used to analyze the relationship between leptin level and IMT , and person correlation was further used to analyze the affinity degree between leptin level and IMT. Results Compared with the NGT group, the inter-group comparison showed that leptin level was significantly increased in the IFG, IGT and (IFG + IGT) groups (P < 0.05, respectively). Compared with the IFG and IGT groups, IMT and the leptin level were increased in the (IFG + IGT) group (P < 0.05, respectively). The multiple linear regression analysis showed that leptin level was correlated with the increase of IMT in the (IFG + IGT) group (P < 0.05), but not in the IFT group and the IGT group. Conclusion The leptin level in the IGR group and the IMT in the IFG + IGT ) group were significantly increased , the leptin level was closely associated with IMT.

Objective To study the levels of CD62P and CD44 in the peripheral blood of children with lupus nephritis (LN) and their clinical significances were investigated. Methods Twenty-two children with active LN were divided into two groups by their clinical features,nephritic syndrome group (NS group,12 patients) and nonnephritic syndrome group (non NS group, 10 patients). Those patients were also divided into two groups according to their pathologic grading,grade Ⅱ+Ⅲ group (6 patients) and grade Ⅳ+Ⅴ group(16 patients).According to their tubulointerstitial lesions (TIL), those patients were divided into three groups, TIL grade 0 group (5 patients), grade Ⅰ group (13 patients), grade Ⅱ group (4 patients). The blood of the 18 patients who were in inactive state after treatment were retested blood again. The levels of CD62P and CD44 in the peripheral blood were assayed by radioimmunoassay (RIA) and enzyme-linked immunoabsorbant assay (ELISA) in LN children and in 20 normal age and sex-matched controls, and their correlation with clinical peripheral blood levels of CD62P and CD44 in NS group, grade Ⅳ+Ⅴ group were significantly higher than CD44 were positively correlated with 24-hour proteinuria,ESR, urine NAG, urine β2-MG and the TIL grade (P<0.05 and P<0.01, respectively), but negatively correlated with the levels of serum complement 3 (C3) and albumin (ALB) (P<0.05).The levels of CD62P was positively correlated with those of CD44 (P<0.05). Conclusion CD62P and CD44 may be involved in the pathogenesis of LN. The peripheral blood levels of CD62P and CD44 in LN children could be used as one of the indicators for lupus activity, severity, treatment effectiveness and prediction of outcome.

Objective To evaluate the role of mitochondrial permeability transition pore (mPTP) in attenuation of myocardial ischemia-reperfusion (I/R) injury by sufentanil postconditioning in rats.Methods Sixty male Sprague-Dawley rats,aged 14-15 weeks,weighing 350-420 g,were randomly divided into 4 groups (n =15 each):sham operation group (group S),group I/R,cyclosporin A group (group CP) and sufentanil postconditioning group (group SP).Myocardial I/R was produced by occlusion of left anterior descending branch of coronary artcry for 30 min followed by reperfusion.In groups CP and SP,cyclosporin A 5 mg/kg and sufentanil 1 μg/kg were injected via the jugular vein at 5 min before reperfusion respectively,while the equal volume of normal saline was injected in group I/R.At 10 min of reperfusion,hearts were excised,the myocardial mitochondria were immediately isolated and the activity of mPTP was measured by spectrophotometry.MAP and HR were recorded at 30 min of equilibration,at 30 min of ischemia and at 120 min of reperfusion and rate-pressure product (RPP) was calculated.Arterial blood samples were obtained at 120 min of reperfusion for determination of the plasma cardiac troponin Ⅰ (cTnⅠ) concentration.The animals were then sacrificed for determination of infarct size (IS) and area at risk (AAR),and IS/AAR was calculated.The mitochondrial ultra-structure was examined with electron microscope.Results Compared with group S,the mPTP activity and plasma cTnI concentration were significantly increased,and MAP and RPP were significantly decreased in the other three groups (P ＜ 0.05).Compared with group I/R,the mPTP activity,plasma cTnI concentration and IS/ARR were significantly decreased in groups CP and SP,and MAP was significantly increased in group CP (P ＜ 0.05).Compared with group CP,MAP was significantly decreased (P ＜ 0.05),while no significant change was found in the other indexes in group SP (P ＞0.05).Significant mitochondrial swelling,and disruption and disappearance of cristae were showed in I/R group.The mitochondrial structure was more complete in CP and SP groups than that in group I/R,and the disrupted cristae were found in a small number of mitochondria in CP and SP groups.Conclusion The mechanism by which sufentanil postconditioning reduces myocardial I/R injury is related to inhibition of mPTP opening in rats.

Objective To investigate the effect of type 2 diabetes mellitus (DM) on the attenuation of myocardial ischemia-reperfusion (I/R) injury by sufentanil postconditioning in rats.Methods Male pathogen-free Sprague-Dawley rats,weighing 160-180 g,were used in the study.A model for type 2 DM was established by the feeding of high-fat diet-induced insulin resistance and intraperitoneal streptozocin 35 mg/kg.DM was confirmed by blood glucose level ≥ 16.7 mmol/L one week after injection.Eighteen type 2 diabetic rats were randomly divided into 3 groups (n =6 each):DM sham operation group (DM-S group) ; DM-I/R group; DM sufentanil postconditioning group (DM-SP group).Another 18 healthy nondiabetic rats were chosen and randomly divided into 3 groups (n =6 each):nondiabetes mellitus sham operation group (NDM-S group) ; nondiabetes mellitus I/R group (NDM-I/R group) ; nondiabetes mellitus sufentanil postconditioning group (NDM-SP group).Myocardial I/R was induced by 30 min occlusion of the left anterior descending branch of coronary artery (after 30 min of equilibration) followed by 120 min of reperfusion.Sufentanil 1.0 μg/kg was injected via the right jugular vein 5 min before reperfusion in NDM-SP and DM-SP groups.MAP,SP and HR were recorded immediately before ischemia,at 30 min of ischemia and at 120 min of reperfusion and rate-pressure product (RPP) was calculated.Arterial blood samples were collected at 120 min of reperfusion for measurement of plasma cardiac troponin Ⅰ (cTnⅠ) concentration.The rats were then sacrificed for determination of the myocardial infract size.Results MAP and RPP were decreased,while the plasma cTnl concentration was increased during reperfusion in diabetic and nondiabetic rats.Sufentanil postconditioning decreased the myocardial infract size and plasma concentrations of cTnⅠ,and increased MAP and RPP during reperfusion in nondiabetic rats,but had no effect on the parameters in diabetic rats.Conclusion Type 2 DM interferes with sufentanil postconditioning-induced myocardial protection in rats.

Objective:To analyze the levels of serum calcium,phosphate,fibroblast growth factor 23 (FGF23),and Klotho proteins in patients with chronic kidney disease (CKD),and to investigate the correlations of FGF23 and Klotho proteins with cardiac complicates in patients with chronic kidney disease-mineral and bone disorder (CKD-MBD).Methods:A total of 180 CKD-MBD patients were enrolled for this study.Among them,60 patients underwent regular hemodialysis,60 patients did not undergo renal replacement therapy and 60 patients were diagnosed as second hyperparathyroidism (SHPT).Thirty age and gendermatched health volunteers served as controls.Serum samples were collected and tested,and the demographical,clinical and biochemical data were all recorded.FGF23 and Klotho levels in serum samples were analyzed by enzyme-linked immunosorbent assay.Data of echocardiography and plain abdominal X rays were collected as well.The influential factors for cardiovascular injury,the relationship between biochemical indexes and ectopic calcification,and the correlations of FGF23 and Klotho with cardiac complicates were analyzedResults:Patients,who kept hemodialysis,especially those with SHPT,exhibited an increase in serum FGF23 level while a decrease in serum Klotho protein levels (P＜0.01).Patients with higher levels of serum FGF23 were more likely to have ectopic calcification (OR=4.667),while patients with lower levels of serum Klotho had high risks to get myocardial hypertrophy (OR=3.496).Receiver operator characteristic (ROC) curve analysis showed that the area under the curve (AUC) for FGF23 was 0.778 (P＜0.01) while for Klotho was 0.715 (P＜0.01).Conclusion:Patients,who kept hemodialysis,especially those with SHPT,have a significant increase in serum FGF23 protein levels and a significant decrease in serum Klotho protein levels.Serum FGF23 and Klotho protein levels are closely correlated with left ventricular enlargement and hypertrophy.Serum FGF23 and Klotho protein are risk factors for heart.
