Objective To explore incidence of child obesity in Zhengzhou area and intervention measures.Methods In 2001, spot check was conducted on 5688 cases of high and primary school students ,including 2848 boys and 2840 girls at the age of 7-18.Child obesity was diagnosed by meeting reference BMI value published by Cole et al,conducted comprehensive treatment consisting of massage intervention along channel of traditional Chinese medicine, behavior modification, dietetic and sport adjustment for 22 cases of simple obesity children (7-15 years old, 18 boys, 4 girls) selected for one month, and follow-up survey 6 months after treatment.Results Five thousands,six hundreds and eighty-eight high and primary school students investigated had an overweight incidence of 15.4%, an obesity incidence of 3.2%,boys' overweight incidence and obesity incidence(19.2%,4.6%) were remarkably higher than those of girls (11.5%,1.7% P<0.001). Overweight incidence of various age groups evidently differed(χ2=42.88 P<0.001) with the group of 8-15 years old children as popular. Incidence of various age groups also differed(χ2=21.28 P<0.05) with 7-10 years old and 14-15 years old children as popular. After one-month treatment, weight of all the 22 cases of fat children decreased from (76.45±19.87) kg upon hospitalized to (69.06±17.98) kg with a decrease of (7.43±2.58)kg, BMI value decreased from (31.05±3.96) before treatment to (27.72±3.54).Weight and BMI value before and after treatment differed evidently (t=13.6,12.88 P<0.01), and weight and BMI value decrease were remarkably related with those upon hospitalized (r=0.77 P<0.01;r=0.49 P<0.05).Conclusions Incidence of child obesity has been increasing in recent years, comprehensive treatment consisting of massage intervention along channel of traditional Chinese medicine, behavior modification, dietetic and sport adjustment have good curative effect and are comfortable, well received by children and suitable to promote and apply.

ObjectiveTo investigate the prevalence and distribution characteristics of dental fluorosis of children aged 8 - 12 in Wushan and Fengjie counties of Chongqing and to provide a scientific basis for prevention and control of the disease.MethodsTwenty townships(towns) in Fengjie county and 18 in Wushan county were selected as survey points by random cluster sampling in 2010.Dental fluorosis of all the children aged 8 - 12 was examined with Dean index.The detection rate of children's dental fluorosis,defect rate and dental fluorosis index were compared between the two counties.Results Totally 38 209 children aged 8 - 12 were investigated.The total detection rate of dental fluorosis was 43.09％( 16 466/38 209) in the two counties.The detection rates of dental fluorosis in Wushan and Fengjie were 48.98％ (9397/19 186)and 37.16％(7069/19 023),respectively,and the difference was statistically significant(x2 =544.03,P ＜ 0.01 ).Total detection rates of dental fluorosis of the five age groups(8,9,10,11,and 12-year-old age groups) were 32.52％(2157/6632),40.07％(2672/6668),43.67％(3420/7831 ),46.01％ (3861/8391) and 50.14％ (4356/8687),respectively,and the difference was statistically significant (x2 =510.50,P ＜ 0.01),Dental fluorosis indexes in Wushan and Fengjie were 0.713 and 0.485,respectively.Defect rates of dental fluorosis in Wushan and Fengjie were 4.05％ (777/19 186) and 1.57％(298/19 023),respectively.Conclusions The total detection rate of dental fluorosis of the two counties is still high,which gradually increases with age.Wushan is still an endemic area of dental fluorosis,and Fengjie is at the edge of the

OBJECTIVETo summarize the experience and lessons from 100 cases retropubic radical prostatectomy performed in the past 10 years.

METHODSFrom July 1999 to July 2009, we performed 100 cases of retropubic radical prostatectomy, of which 84 were followed up for 3 - 120 months. We analyzed their preoperative age, PSA level, amount of intraoperative blood transfusion, operation time, urinary continence, penile erectile function, stricture of the anastomotic stoma and Qmax.

RESULTSThe mean age, PSA level, amount of intraoperative blood transfusion, operation time were 66.8 yr, 20.1 ng/ml, 585.7 ml and 198.9 min; the recovery rates of bladder control at 3, 6 and 12 months postoperatively were 65.5%, 81.7% and 92.4%, respectively. At 12 months after surgery, penile erection was restored in 19 cases (42.2%), anastomotic stoma stricture developed in 5 (5.9%), Qmax averaged 20.5 ml/min, biochemical recurrence was found in 13, and 1 died from prostate cancer.

CONCLUSIONRetropubic radical prostatectomy is a desirable procedure for the treatment of local prostate cancer, in which ligation of the puboprostatic ligament and prostatic venous plexus before cutting off the ligament helps improve urinary continence, protection of the neurovascular bundle and collateral pudendal artery contributes to the recovery of penile erectile function, and proper connection of urethral and bladder mucosa can reduce anastomotic stoma stricture. Postoperative external-beam radiotherapy for those with T3a or local lymph node metastasis could decrease biochemical recurrence.

BACKGROUNDBoth uniportal and triportal thoracoscopic lobectomy and sublobectomy are feasible for early-stage non-small cell lung cancer (NSCLC). The aim of this study was to compare the perioperative outcomes of uniportal and triportal thoracoscopic lobectomy and sublobectomy for early-stage NSCLC.

METHODSA total of 405 patients with lung lesions underwent thoracoscopic lobectomy or sublobectomy through a uniportal or triportal procedure in approximately 7-month period (From November 2014 to May 2015). A propensity-matched analysis, incorporating preoperative variables, was used to compare the short-term outcomes of patients who received uniportal or triportal thoracoscopic lobectomy and sublobectomy.

RESULTSFifty-eight patients underwent uniportal and 347 patients underwent triportal pulmonary resection. The conversion rate for uniportal and triportal procedure was 3.4% (2/58) and 2.3% (8/347), respectively. The complication rate for uniportal and triportal procedure was 10.3% and 9.5%, respectively. There was no perioperative death in either group. Most patients had early-stage NSCLC in both groups (uniportal: 45/47, 96%; triportal: 313/343, 91%). Propensity score-matching analysis demonstrated no significant differences in operation time, intraoperative blood loss, numbers of dissected lymph nodes, number of stations of lymph node dissected, duration of chest tube, and complication rate between uniportal and triportal group for early-stage NSCLC. However, the duration of postoperative hospitalization was longer in the uniportal group (6.83 ± 4.17 vs. 5.42 ± 1.86 d, P = 0.036) compared with the triportal group.

CONCLUSIONSUniportal thoracoscopic lobectomy and sublobectomy is safe and feasible, with comparable short-term outcomes with triportal thoracoscopic pulmonary resection. Uniportal lobectomy and sublobectomy lead to similar cure rate as triportal lobectomy and sublobectomy for early NSCLC.

OBJECTIVETo investigate the rule of lymph node metastasis of adenosquamous carcinoma of the lung.

METHODSThe data of 361 surgically treated patients with adenosquamous carcinoma of the lung from October 1965 to June 2003 were collected and retrospectively reviewed. The classification of regional lymph node stations and TNM stage were determined according to the UICC criteria (1997). The route and patterns as well as influencing factors of lymph node metastasis were analyzed by SPSS 10.0 software. The median follow-up period was 5.5 years (range, 1.4 to 23.4 years).

RESULTSThe analysis of the route of mediastinal lymph node metastasis in the 361 cases showed that the tumor originated in the left upper lobe firstly metastasized to station 5 (A-P window), tumor in the right upper lobe to the station 4 (lower paratracheal), then secondly to station 7 (subcarinal), lastly to station 3 from the tumor in the left upper lobe or to the station 2 from the tumor in the right upper lobe. It was found that the tumors originated from the lower lobe, firstly metastasized to station 7, secondly to station 9 or 4 from the right lobe; or station 5 from left lower lobe, lastly to station 3 or 2 in the mediastinum. For the tumor in the middle lobe, mainly metastasized to station 7, 4 and 2. The skip mediastinal lymph node metastasis but N1 negative most commonly metastasized to station 7, then to station 4 from the tumor in the right lung and 5 from the tumor in the left lung. The prognosis of patients with a single skipping metastasis to mediastinal lymph node (N1-, SMLN) was better than that in the other patients with mediastinal lymph node metastases.

CONCLUSIONThe lung cancer growing in a different location has a different route and skipping metastasis to mediastinal lymph nodes. The patterns of lymph node metastasis affect prognosis. The prognosis of patients with single skipping metastasis to mediastinal lymph nodes but negative pulmonary hilar lymph node is better than that in the other patients with multiple station mediastinal lymph node metastases. The "N1-, SMLN" pattern ought to be considered as a special lymph nodal metastasis with better prognosis.

Background: Thymoma is an uncommon tumor without a widely accepted standard care to date. We aimed to investigate the clinicopathologic variables of patients with thymoma and identify possible predictors of survival and recurrence after initial resection. Methods: We retrospectively selected 307 patients with thymoma who underwent complete resection at the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College (Beijing, China) between January 2003 and December 2014. The associations of patients' clinical characteristics with prognosis were estimated using Cox regression and Kaplan–Meier survival analyses. Results: During follow-up (median, 86 months; range, 24–160 months), the 5- and 10-year disease-free survival (DFS) rates were 84.0% and 73.0%, respectively, and the 5- and 10-year overall survival (OS) rates were 91.0% and 74.0%, respectively. Masaoka stage (P < 0.001), World Health Organization (WHO) histological classification (P < 0.001), and postoperative radiotherapy after initial resection (P = 0.006) were associated with recurrence (52/307, 16.9%). Multivariate analysis revealed that, after initial resection, WHO histological classification and Masaoka stage were independent predictors of DFS and OS. The pleura (25/52, 48.0%) were the most common site of recurrence, and locoregional recurrence (41/52, 79.0%) was the most common recurrence pattern. The recurrence pattern was an independent predictor of post-recurrence survival. Patients with recurrent thymoma who underwent repeated resec-tion had increased post-recurrence survival rates compared with those who underwent therapies other than surgery (P = 0.017). Conclusions: Masaoka stage and WHO histological classification were independent prognostic factors of thymoma after initial complete resection. The recurrence pattern was an independent predictor of post-recurrence survival. Locoregional recurrence and repeated resection of the recurrent tumor were associated with favorable prognosis.

Objective To compare the effects of intracoronary infusion of mononuclear stem cells (MNCs) or mesenchymal stem cells (MSCs) in patients with dilated cardiomyopathy (DCM).Methods DCM patients with left ventricular ejection fraction ( LVEF ) ＜ 40％ were randomized to intracoronary infusion of MNCs [ (5.1 ± 2.0) × 108,n =16] or MSCs [ (4.9 ± 1.7 ) × 108,n =17 ] or equal volume normal saline ( n =20 ) through the guiding catheter. Changes of left ventricular end-diastolic diameter (LVEDd),LVEF and myocardium perfusion defects were assessed before and at (30 ±3) days and (90 ± 7) days after the procedure.Malignant cardiovascular events were also recorded.Results ( 1 ) One month after the procedure,LVEF in transplantation groups significantly increased compared to before procedure ( all P ＜0.05),and significant increase of LVEF was observed only in MSCs transplantation group compared to control group ( P ＜ 0.05 ).However,absolute changes of LVEDd and perfusion defects of myocardium were similar among and within groups (P ＞ 0.05 ).(2)Gomparing with before procedure and control group,LVEF in transplantation groups increased significantly in three months after the procedure (P ＜ 0.05 ),but there were no significant differences between transplantation groups ( P ＞ 0.05 ).LVEDd and myocardium perfusion defects in transplantation groups improved significantly compared with that of before procedure (P ＜0.05 ),while significant decrease of myocardium perfusion defects was only observed in patients treated with MSCs compared with control group at three months after procedure ( P ＜ 0.05 ). ( 3 ) There were no significant differences in major cardiovascular events between transplantation group and control during followup ( P ＞ 0.05).Conclusions Intracoronary bone marrow stem cells transplantation is safe and effective for DCM patients while the efficacy of MSCs and MNCs transplantation is comparable.

OBJECTIVETo compare the instructive value of the 6th and 7th editions of the UICC-AJCC staging system in prognosis of esophageal cancer (EC) patients.

METHODSThe staging and prognosis of 1397 esophageal carcinoma patients undergoing curative resection from Jan. 2003 to Dec. 2006 in our hospital were retrospectively reviewed and analyzed according to the 6th AJCC staging system and the 7th UICC-AJCC staging system.

RESULTSThe 5-year overall survival (OS) of EC patients with curative resection was 38.5% (481/1250 cases), with a follow-up rate of 89.5% (1250/1397 case). In overall terms, both the editions were statistically significant discriminators of OS (P < 0.05). The 5-year OS of stages I, II and III patients were 64.9%, 43.5%, 25.2% according to the 6th edition, and 63.5%, 44.5%, 23.5% according to the 7th edition, respectively. Distinct differences in survival were present among patients categorized as stage Ia and Ib according to the 7th edition (P < 0.05), with a 5-year OS of 80.0% and 58.3%, respectively. Similarly, according to the 7th edition, the 5-year overall survivals (OS) of the stages IIIa, IIIb and IIIc patients were 28.2%, 18.4% and 16.7%, respectively, showing that the prognoses were significantly different (P < 0.05). In addition, according to the 7th edition, the prognoses of patients in stages N0, N1, N2 and N3 were also significantly different (P < 0.01), and the 5-year OS were 50.0%, 31.5%, 18.7% and 16.7%, respectively.

CONCLUSIONSBoth the 6th and 7th editions of UICC-AJCC staging system are significant discriminators for survival of esophageal cancer patients. The 7th edition is proved to be more accurate in prognosis. The number of lymph node metastases is an important predictor of prognosis.

BACKGROUNDCoronary artery disease (CAD) is generally considered as a disease of middle-aged men. It is widely accepted that the risk for CAD of premenopausal women is low because of hormone protection. Based on our clinical experience, more and more premenopausal women suffer from angina and myocardial infarction without adequate concern. Even now, there are still limited detailed data to describe the characteristics, mechanism and prognosis of premenopausal CAD patients. This article aimed to analyze the clinical and angiographic characteristics of premenopausal women with CAD.

METHODSA total of 565 premenopausal women and 721 postmenopausal women (56 - 60 years old) who underwent coronary angiography for the first time from April 2004 to December 2007 were enrolled. The clinical data and coronary angiographic characteristics (presence, localization, length and severity) were compared between the premenopausal and postmenopausal CAD groups.

RESULTSPremenopausal CAD patients presented less frequently with hypertension, diabetes mellitus and dyslipidemia compared with postmenopausal CAD patients (55.0% vs 66.0%, 15.0% vs 31.5%, 23.9% vs 37.4%, respectively; all P < 0.05). Although we found more frequent involvement of single vessel in premenopausal CAD (43.2% vs 26.9%, P = 0), and triple vessels in postmenopausal (56 - 60 years old) CAD patients (33.8% vs 20.4%, P = 0), much more severe lesions (> or = 90%) at left main (2.9% vs 1.1%, P = 0.048) and proximal left anterior descending artery (LAD) (28.2% vs 16.6%, P = 0) in the premenopausal CAD group were found.

CONCLUSIONPremenopausal women with chest discomfort are always found to have obvious atherosclerosis, more inclined to be located at the left main and proximal LAD, which is a strong predictor of an adverse clinical outcome.
