Objective To investigate the distribution of Helicobacter pylori (Hp) infections among general population in Tianjin. Methods Individuals (n=11 096) who visited our hospital for medical examination and H. Pylori infection screen were included in the research objects. Rapid urease method was utilized to rapidly detect H. pylori infection among the popultion. Individuals were grouped based on their gender, age and occupations, and then were analyzed. Results H. pylori-positive rate was 30.52%(3 386/11 096) in 11 096 individuals, in which there were 34.77%(1 784/5 131) male and 26.86%(1 602/5 965) female respectively. Individuals were divided into 5 groups according to their ages:19 to 29 years old group, 30 to 39 years old group, 40 to 49 years old group, 50 to 59 years old group, 60 to 69 years old group and 70 to 92 years old group. The positive rates of H. pylori increased with age:19.50%( 379/1 944 ) in 19-29 years old group, 25.82%(650/2 517 ) in 30-39 years old group, 31.59%( 908/2 874 ) in 40-49 years old group, 37.48%(915/2 441 ) in 50-59 years old group, 41.09%( 353/859 ) in 60-69 years old group and 39.18%(181/462) in 70-92 years old group. The differences in positive rates between different age groups were all of statistically significant (P<0.05). Individuals were also divided into seven groups according to their occupations: medical worker group, worker group, teacher group, engineer group, clerk group, civil worker group and other career group. The positive rates of H. pylori infection were 25.42%(586/2 305), 29.35%(1 062/3 618), 30.61%(360/1 176), 32.49%(116/357), 33.44%(205/613), 34.52%(455/1 318)and 35.23%(602/1 709) respectively. The positive rate was 25.42% (586/2 305) medical workers, which was lower than that of other occupation groups with significant difference (P<0.002). Conclusion Good management of H. pylori diagnosis and treatment in mid-dle age and elderly together with popularizing knowledge of H.pylori prevention can effectively reduce H.pylori incidence.

Objective To evaluate the safety and efficacy of combining radiofrequency ablation(RFA) with arsenious acid(AA) locally to treat liver VX2 tumor in rabbits,and to explore its mechanism.Methods Twenty-eight New Zealand White rabbits with implanted liver VX2 tumors were randomly divided into four groups: control group(n= 7),AA group(n=7),RFA group(n=7),and combination(RFA+AA) group(n=7).ALT was measured before treatment and on the day 0,day 3,day 7 and day 14 after treatment,meanwhile ultrasonic(US) examination was performed.All rabbits were killed 14 days after treatment.Vascular endothelial growth factor(VEGF) was examined by immunohistochemistry,and the relationship of VEGF and gross tumor volume was analyzed.Results Combination(RAF+AA) therapy caused little damage to hepatic function but had better inhibited tumor growth.The level of VEGF in AA,RFA and RAF+AA group was lower than that of the control group(P

ObjectiveTo explore the prevalence of metabolic syndrome (MS) in patients with primary aldosteronism(PA) and the correlation with plasma aldosterone concentration. MethodsThe incidence of MS was retrospectively analyzed in 216 patients with PA from October 2008 to July 2010. Results( 1 ) The prevalence of MS was 47. 69％ in the patients with PA. As the individual components of MS, the incidence of overweight/obesity,raised blood triglyceride ( TG ) level, impaired glucose regulation ( IGR), lowered high-density lipoprotein-cholesterol ( HDL-C), and diabetes mellitus( DM ) was 51.13％, 22. 52％, 19.62％, 3.82％, and 2.94％, respectively. (2)The most common combination of MS components was overweight/obesity+high TG, followed by overweight/obesity+ lowered HDL-C, and overweight/obesity + DM, with the incidence of 35. 19％,15.74％, and 11.57％,respectively. (3) The incidence of overweight/obesity and IGR was raised progressively with the increasing plasma aldosterone level. (4) The prevalence of MS was significantly lower in Han patients (45.3％) than in Uygur ( 64. 0％ ), but higher than in Kazakh (42. 9％, both P＜0. 05 ). ConclusionsThe prevalence of MS in patients with PA was high. The prevalences of MS and its components were gradually rising with plasma aldosterone level.

ObjectiveTo investigate the characteristics of left ventricular structural damage in patients with primary aldosteronism(PA).MethodsA total of 438 inpatients with hypertension from January 2007 to June 2010 were screened for PA,and diagnosis was made in 213 PA patients and 225 patients with essential hypertension (EH).The left ventricular structure of all subjects was evaluated according to the results of echocardiographic measurements.Results The duration of hypertension and plasma aldosterone level in patients with PA were significantly higher (P＜ 0.01 ),while the serum potassium and plasma renin activity were significantly lower (P＜0.01 ) than those in patients with EH.The interventricular septum thickness,left ventricular end-diastolic dimension,left ventricular mass index (LVMI),left ventricular end-diastolic volume,and stroke volume in patients with PA were significantly higher than those in EH patients( P＜0.01 ) after the duration of hypertension was corrected.In patients with PA,the prevalence of left ventricular hypertrophy (LVH) was higher than that in EH patients ( 53.1％ vs 33.8 ％,x2 =16.57,P ＜ 0.01 ). Normal left ventricular geometry ( NG ),concentric remodeling ( CCR ),concentric hypertrophy( CCH),and eccentric hypertrophy (ECH) were found respectively in 24.9％,22.1％,22.1％,and 30.9％ of patients with PA.Multiple stepwise regression analysis showed that the seated plasma aldosterone level (β=0.43,P ＜ 0.01 ) and systolic blood pressure (β =0.45,P ＜ 0.01 ) were the main factors that influenced LVMI.The course was the main parameter that influenced relative wall thickness(β=0.011,P＜0.05 ).Conclusion The prevalence of LVH is higher in patients with PA than that in EH patients.The eccentric hypertrophy is the most common left ventricular geometrical pattern in patients with PA.

Objective To study the relationship between the clinic-pathological features and pain symptoms in patients with endometriotic cyst(EM).Methods The medical data of symptoms,laparoscopy and pathology examination in 416 patients with endometriosis were studied retrospectively.All cases were divided into two groups on the existence of ovarian endometrioma,including 338 patients in cyst group and 78 cases in non-cyst group.The relationship between clinical symptoms and location and type of endometrioma was studied.Results(1)Serum CA125 level:the level of CA125 were(61 ± 39)kU/L in cyst group(28 ± 24)kU/L in non-cyst group,which reached statistical difference(P ＜ 0.01).(2)Pathological features:among 338 cases,34.0％ of cyst were on left side(115/338),26.3％ were right side(89/338),and 39.6％ were on both side(134/338).And 95.8％(324/338)of cases were combined with the other type of endometriosis,which were 48.5％(164/338)with peritoneal endometriosis,47.3％(160/338)with deep infiltrating endometriosis(DIE).In cystic patients,the incidences of endometriosis lesion were 13.9％(47/338)on the uterine surface,38.5％(130/338)on obstruction of cul-de sac,40.5％ (137/338)on utero-sacral ligament of DIE,which were significantly higher than 5.1％,(4/78),9.0％ (7/78)and 28.2％(22/78)in noncyst group.(3)Pain symptom:the incidence and degree of dysmenorrhea and dyschezia had no statistical difference between two groups(P ＞ 0.05),and the incidence of chronic pelvic pain(CPP)of 24.6％(83/338)and dyspareunia of 29.9％(101/338)in the cyst group were significantly lower than 35.9％(28/78)and 44.9％(35/78)in non-cyst group(P ＜ 0.05).The incidence of dysmenorrheal was 85.1％(114/134)in cases with bilateral cyst,which was higher than 74.0％(151/204)in cases with single cyst.The incidence of dysmenorrheal and dyschezia in moderatesevere adhesion was 89.0％(138/155)and 18.7％(29/155),which was significantly higher than 68.8％ (126/183)and 8.2％(15/183)in mild adhesion.In the patients cyst existed with DIE,the risk of dysmenorrheal,CPP,dyspareunia,and dyschezia were obviously raised(OR respectively was 5.17,3.01,3.05,2.75).Conclusions The endometriotic cyst often co-exists with other type of endometriotic lesions.Ovarian endometrioma was associated with lesion localized on uterine surface,cul-de-sac,sacrum ligament.The risk of all the pain symptoms would be raised when the endometriotic cyst co-exit with the DIE lesions.So the treatment for DIE lesions was as same important as the endometriotic lesions in order to relieve pain symptoms and delay the relapse.

In order to properly understand the physiological characteristics of children and apply principles of recuperative medical care, chun-yangis textually studied from etymology and the original intention of Taoism.Etymologically, both chun and yang have their original meaning and derived meanings.Chun involves tiny, pure and powerful meanings, while yang is about ferventness, quickness and activity.In Taoist internal elixir, chun-yang has 3 meanings, including the boundary between fairyland and earth, congenital yin and yang, and virginity.However, chun-yang is not powerful yang or pure yang.Children's chun-yangis firstly seen in Luxin Jing, which is indeed influenced by Taoism.The view of chun-yang equaling to powerful yang conflates the original and derived meanings of chun and yang, which is also a misunderstanding of Taoist chun-yang.There are two aspects of chun-yang theory in Taoism:jeune yang and energetic yang.In this regard, children's chun-yang should also have the dual meanings.

Background: Currently available guidelines contain conflicting recommendations on the management of blood pressure (BP) in patients with diabetes mellitus (DM). Therefore, it is necessary to appraise the guidelines and summarize the agreements and differences among recommendations. Methods: Four databases and the websites of guideline organizations were searched for guidelines regarding BP targets and thresholds for pharmacologic therapy in DM patients, and the included guidelines were appraised with the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. Results: In 6,498 records identified, 20 guidelines met our inclusion criteria with 64.0% AGREE II scores (interquartile range, 48.5% to 72.0%). The scores of the European and American guidelines were superior to those of the Asian guidelines (both adjusted P<0.001). Most of the guidelines advocated systolic BP targets <130 mm Hg (12 guidelines, 60%) and diastolic BP targets <80 mm Hg (14 guidelines, 70%) in DM patients. Approximately half of the guidelines supported systolic BP thresholds >140 mm Hg (10 guidelines, 50%) and diastolic BP thresholds >90 mm Hg (nine guidelines, 45%). The tiny minority of the guidelines provided the relevant recommendations regarding the lower limit of official BP targets and the ambulatory BP monitoring (ABPM)/home BP monitoring (HBPM) targets and thresholds in DM patients. Conclusion The lower official BP targets (<130/80 mm Hg) in patients with DM are advocated by most of the guidelines, but they contain conflicting recommendations on the official BP thresholds. Moreover, the gaps regarding the lower limit of official BP targets and the ABPM/HBPM targets and thresholds need to be considered by future study.

Objective:To evaluate the efficacy and safety of transhepatic arterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKI) and programmed death-1 (PD-1) inhibitors in the treatment of patients with initially unresectable hepatocellular carcinoma.Methods:The clinical data of 42 patients with initially unresectable hepatocellular carcinoma who were admitted to the Department of Hepatobiliary and Pancreatic Surgery of the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2022 were included. There were 31 males and 11 females, with a median age of 56 years old (range, 45-72 years old). All patients received TACE+ TKI+ PD-1 inhibitor combined treatment. The systemic treatment cycles were calculated by the regimen of immunotherapy. The timing of local treatment depends on tumor size, blood supply and treatment response. Patients were followed up through hospitalization, outpatient visits and telephone review. The Kaplan-Meier curves were obtained for survival analysis.Results:The dosing cycle to achieve optimal imaging response in the patients was 4 (3, 7) [ M( Q1, Q3)], with a systemic treatment time of 141 (65, 194) d [ M( Q1, Q3)] and 2 (1, 3) times [ M( Q1, Q3)] of local treatments. All patients were evaluated by modified response evaluation criteria in solid tumors criteria after treatment, including nine patients with complete response (CR), 21 with partial response, eight with stable disease, and four with progressive disease. Objective response rate and disease control rate were 71.4% (30/42) and 90.5% (38/42), respectively. Treatment-related adverse reactions occurred in 85.7% (36/42) of patients and grade Ⅲ or Ⅳ adverse reactions occurred in 16.7% (7/42). There was no level Ⅳ adverse reactions. All adverse reactions were controlled after dose reduction and symptomatic treatment. Thirteen patients (31.0%, 13/42) redeemed resectable after treatment and underwent radical surgery. Seven patients had pathological CR after surgery. In two patients, the pathological residual cancer tissue was less than 10%. The cumulative overall survival rates of the 42 patients at 6 months, 1 year, 1.5 years after treatment were 100%, 91.7%, and 65.0%, respectively. The postoperative 1-year survival rate of patients undergoing surgery after successful conversion was 83.3%. Conclusion:This study preliminarily showed the safety and efficacy of TACE, TKI, and PD-1 inhibitor combined therapy in patients with initially unresectable hepatocellular carcinoma.
