The acute phase of ischemic stroke patients are often treated with both Chinese patent medicine:and western medicine therapies in clinical practice. This research included 27,678 cases of the acute phase of ischemic stroke came from 14 3A level hospitals. We collected data from patients with ischemic stroke who used both Chinese patent medicine and western medicine and were hopitalized within 14 days from hospital information system (HIS). Constructing complex network of Chinese patent medicine and western medicine were found to show scale-free network. Hierarchical structure of the core algorithm was used to analyze the characteristics of combined core Chinese patent medicine and western medicine in admission condition of "acute", "critically", and "general" of ischemic stroke acute phase patient within one day, 2-3 days, 4-7 days and 8-14 days. We found that the core Chinese patent medicine mainly used for activate blood and resolve stasis medicine, and phlegm eliminating brain refreshing medicine in all kinds of patients, but the phlegm eliminating brain refreshing medicine were used to reduce with time elapsing. The core western medicine mainly used for anti-platelet medicine, improve circulation medicine, neuroprotective medicine, anticoagulants medicine and dehydration medicine. The dehydration medicine as the core western medicine for critically patients within 14 days, but the patients for general admission as core western medicine within 3 days. The neuroprotective medicine was used to decreases after 7 days in hospital. Combination of Chinese patent medicine and western medicine were mainly for neuroprotective medicine + activate blood and resolve stasis medicine, and anti-platelet medicine + activate blood and resolve stasis medicine, and improve circulation medicine + activate blood and resolve stasis medicine. The phlegm eliminating brain refreshing medicine was mainly combined with neuroprotective medicine by urgent and general admission condition patients, and it was more combined with dehydration medicine by critically admission condition patients. This research found that the dynamic characteristics for the combination of Chinese patent medicine and western medicine of acute phase of ischemic stroke patients by big data analytics and complex networks modeling, and provide basis for acute phase of ischemic stroke patients, it provide basis for ischemic stroke treatment strategy making.

Objective To improve the diagnosis and treatment quality of juxtaglomerular cell tumor of the kidney. Methods Three patients(2 females, 1 male) were diagnosed with juxtaglomerular cell tumor of kidney and underwent nephron-sparing surgery. Case 1 was female, 15 years old. She presented with hypertention of 245/135 mm Hg. The serum kalium was 2.5--3.0 mmol/L. Thelaboratory examination suggested that in decubitus and standing position, the plasma renin activity (PRA) was 2.2 and 3.5 μg · L-1 · h-1 , angiotensin Ⅱ (ATⅡ) was 181.2 and 481.4 ng/L; aldosterone(ALD) was 332.4 and 747.9 pmol/L, respectively. Dynamic enhanced CT scanning demonstrated a tumor with the diameter of 1.3 cm in right kidney. Case 2 was male, 39 years old. He presented with hypertention of 180/120 mm Hg. The serum kalium was 2. 7--3.0 mmol/L. In decubitus and standing position, PRAwas8.1 and 9.2 μg·L-1 · h-1, ATⅡ was 198.3 and 279.1 ng/L, ALD was 285.3 and 761.7 pmol/L, respectively. Dynamic enhanced CT scanning showed a tumor with the diameter of 1.2 cm in right kidney. Case 3 was female, 26 years old. She presented with hypertention of 210/120 mm Hg. The serum kalium was 4. 1 mmol/L. In decubitus and standing position, PRA was 0.1 and 0.3 μg · L-1·h-1 , ATⅡ 56.2 and 71.5 ng/L, ALD 321.3 and 421.1 pmol/L, respec tively. On dynamic enhanced CT scanning, a tumor with a diameter of 3.0era was located in left kidney. Results Partial nephrectomy was successfully performed in 3 patients, including 1 (case 2) retroperitoneal laparoscopic surgery. Pathologic examination revealed encapsulated tumors in all cases. Light microscopically, the tumor consisted of clusters of polygonal cells, and the cell had centrally located nuclei and slightly eosinophilic cytoplasm. Thick walled vessels were usually present. The tumors showed positive immunostaining for actin and CD34. Three patients were followed up for 23,4, 26 months respectively and all remained normotensive without any treatment. No recurrence or metastasis occurred. Conclusions Hypertention, increased PRA, secondary aldosteronism, hypokalemia are characteristics for juxtaglomerular cell tumor of the kidney. Dynamic enhanced CT scanning has high sensitivity. Partial nephrectomy or enucleation of tumor are both effective surgical treatment. Retroperitoneal laparoscopic surgery is safe and effective as well.

Objective To describe the distribution of body mass index (BMI) and evaluate the prevalence of overweight and obesity among first to sixth graders in 8 Chinese provinces.Methods Data came from the baseline survey of the Chinese Center for Disease Control and Prevention (CDC) funded project Study on Intervention Models for Main Chronic Diseases among children in China.A stratified random cluster sampling strategy was used to select study participants in 8 provinces,including Inner Mongolia,Jiangsu,Anhui,Shandong,Hunan,Guangxi,Gansu provinces,and Chongqing,with diverse geographical and economic level distributions in China.Counties in each province were stratified into three strata according to economic level,and one county was selected systematically from each stratum.In each county,one urban and one rural elementary school were randomly selected ; and in each school,2-3 classes were randomly selected from each of 1-6 grades.All students in these selected classes were invited for participation.Physical examination was performed by trained local CDC staff using standardized instruments to measure height and weight.Overweight and obesity were diagnosed based on the BMI classification standards for Chinese children and adolescents by Working Group for Obesity in China (WGOC).Results A total of 26558(14225 boy,12333 girl) students aged 6-12 years eventually participated in 8 provinces.The average age was 9.3 ±1.8 years old.Mean BMI among boys (17.0 kg/m2) was higher than that among girls (16.4 kg/m2,t =19.60,P＜0.01).There were statistically significant differences in mean BMI of each age group of boys and 6-11 age groups of girls between urban and rural regions and among those with three economic levels (P＜0.05).The 85th and 95th percentiles of BMI among boys aged 7-11 years in urban region were higher than BMI reference in the standards from WGOC.Lower percentiles were observed among girls aged 7-12 years in rural region.The prevalence of overweight and obesity were 9.3％ and 6.5％ among schoolchildren aged 7-12 years.The prevalence of overweight among boys (10.9％) was higher than that among girls(7.6％,x2 =88.89,P＜0.01) ; while prevalence of obesity were 8.0％ among boys and4.7％ among girls,respectively (x2 =107.17,P＜0.01).The prevalence of overweight was 11.3％ in urban and 7.4％ in rural children(x2 =131.94,P＜0.01).The prevalence of obesity was 8.7％ in urban and 4.3％ in rural children(x2 =188.99,P＜0.01).The prevalences of overweight were 10.3％,8.6％ and 9.0％ in individuals with high,medium,and low economic levels,respectively(x2 =10.76,P＜0.01) ; while the prevalences of obesity were 8.2％,5.6％,and 5.4％,respectively (x2 =51.71,P ＜ 0.01).Conclusions The overall prevalence of overweight and obesity in Chinese school children was high.The prevalence in urban region with high economic level was significantly higher than that in rural region with middle and low economic level.The nutritional and behavioral intervention programs are needed to control the rising trend of obesity in children.

Background Scarring of the filtering bleb is a main cause of filtering surgical failure in glaucoma.It has been reposed that tetrandrine could suppress the proliferation of cultured human fibroblast of Tenons capsule in vitro and thus has the potential effect to prevent scarring after the filtering surgery. Objective Present study was to investigate the anti-cicatricial effect of tetrandrine drug delivery system(Tet DDS)during filtration surgery. Methods Filtration surgery was performed in bilateral eyes of 18 New Zealand white rabbits.The Tet DDS with 0.3 mg Tet,0.2 mg Tet or free-Tet were implanted subcunjunctially during the surgery.The filtering blebs were scored in 1 day,4,7,10,14 days after referring to the corneal thickness and bleb range under the slit-lamp biomicroscopy.The morphology of filtering bleb was assessed by in vivo confocal microscopy in 7 and 14 days after operation.The filtering bleb specimen was prepared in 7 and 14 days for the histopathological examination. Results The filtering bleb scores in Tet DDS implantation groups were significantly higher than those in free-Tet DDS group from 4 days through 14 days after trabeculectomy(P＜0.01),and the scores showed a considerably increase in 0.3 mg Tet DDS group compared with 0.2 mg Tet DDS group from 7 days through 14 days after trabeculectomy(P＜0.05).The filtering blebs of Tet DDS implantation groups were found with distinct subepithelial cystic spaces under the light microscopy and in vivo confocal microscopy on the 7th day and 14th day after surgery.Compared with free-Tet DDS group,the numbers of subepithelial mierocysts were much more(P＜0.01)and the area of microcysts was larger(P＜0.01)in Tet DDS group.The filtering tissue presented with more subepithelial microcysts and larger microcysts range in 0.3 mg Tet DDS group than 0.2 mg Tet DDS group in 7 and 14 days after operation(P＜0.05).The inflammatory cell infiltration wag milder in 0.3 mg Tet DDS group in comparison with 0.2 mg Tet DDS group and free-Ted DDS group.Conclusion Tet DDS has strong inhibitory effects on inflammatory cells activity and fibroblagt activity the early stage after filtering surgery and therefore improve the surgery success rate.

Objective To explore the prevalence and clinical significance of metabolic disorder of lipids, glucose and uric acid at different fibrosis stages of patients with chronic hepatitis B (CHB).Methods From January 2006 to December 2014, 1 812 CHB patients in Department of Infectious Diseases, Shunde Hospital of Southern Medical University were retrospectively enrolled and analyzed.All biochemistry indexes were obtained by automatic biochemical instrument.Polymerase chain reaction was used for detecting serum hepatitis B virus (HBV) DNA, and particles immune detection kit was used for detecting hepatitis B e antigen (HBeAg).In statistical analyses, chi-square test, nonparametric test and Logistic analysis were used.Results The metabolic disorder prevalence in 1 812 CHB patients was as follows, 455 cases (25.1%) with decreased high density lipoprotein, 435 cases (24.0%) with increased uric acid, 342 cases (18.9%) with increased total cholesterol, 254 cases (14.0%) with increased triglyceride, 171 cases (9.4%) with decreased apolipoprotein A, 165 cases (9.1%) with increased apolipoprotein B, 162 cases (8.9%) with increased low density lipoprotein and 117 cases (6.5%) increased fasting blood glucose.Patients who had mild liver fibrosis tended to have metabolic disorders of uric acid (26.4%), total cholesterol (22.8%) and high density lipoprotein cholesterol (20.5%).Patients who had moderate liver fibrosis tended to have metabolic disorders of high density lipoprotein (27.2%) and uric acid (20.9%).Patients who had severe liver fibrosis tended to have metabolic disorders of high density lipoprotein (33.6%) and uric acid (22.2%).Multivariate Logistic regression analysis showed that inflammation activty (OR=17.31, 95% CI: 13.410-22.336, P=0.001), age (OR=1.019, 95%CI:1.005-1.035, P=0.010), sex (OR=1.497, 95% CI: 1.061-2.111, P=0.022), apolipoprotein A (OR=0.50, 95% CI: 0.281-0.892, P=0.019) and HBV DNA (OR=0.904, 95% CI: 0.858-0.952, P=0.001) may be independent predictors of moderate and severe liver fibrosis.Conclusions CHB patients with mild liver fibrosis tend to have metabolic disorders of uric acid, total cholesterol and high density lipoprotein cholesterol;patients with moderate liver fibrosis tend to have metabolic disorders of high density lipoprotein and uric acid;and patients with severe liver fibrosis tend to have metabolic disorders of high density lipoprotein and uric acid.

Objective To report the clinical outcome and prognostic factors for locally recurrent nasopharyngeal carcinoma(NPC)treated with intensity modulated radiotherapy(IMRT).Methods From January 2001 to August 2004,the data of 132 such NPC patients were analyzed retrospectively;104 male and 28 female with a median of 44.5 years(range 21-73 years).Ninety-eight patients(74.2%)were confirmed by biopsy as having NPC:9 with WHO TypeⅡand 89 WHO TypeⅢ.The other 34 patients were only diagnosed by MRI scan because of the extension/invasion was in the base of skull and/or cavernous sinus.Median interval time were 24 months(range 6-184 months).According to the 1992 Chinese Fuzhou Staging System:stageⅠ3.8 %,Ⅱ10.6 %,Ⅲ22.0% andⅣa 63.6%;T1 5.3%,T2 10.6%,T3 22.7% and T4 55.3%.Twenty-two patients had recurrence in the neck lymph nodes.IMRT was given with the sequential tomotherapy system(NOMOS Peacock systems)of 6 MV X-rays.Prescription dose was 60-70 Gy in GTV,with the fractional dose of 1.94-2.8 Gy.Sixty patients were also supplemented with two to six courses of cisplatin-based chemotherapy.Results The median volume of GTV was 39.5 cm~3(range 0.8-158.9 cm~3).The D95,V95,mean dose and fractionation dose of GTV was 66.9 Gy,98.3%,69.8 Gy and 2.32 Gy,respectively.The median follow-up time was 12 months(range,2-47 months).The 1-,2-and 3-year local progression-free rate was 96.4%,88.4% and 85.3%,respectively.The overall 1-,2-and 3-year survival rate was 6.5.9%,49.6% and 41.6%,respectively.Eleven patients developed distant metastases.Forty-seven patients were observed to devdop mucosa necrosis and/or massive hemorrhage in the nasopharynx.On univariate and multivariate analysis,fractional dose and vohane of GTV were significant prognostic factors for overall survival(P=0.016,0.009).Conclusions The local control and survival rate can be improved for patients with locally recurrent nasopharygeal carcinoma after treatment of intensity modulated radiotherapy.The fractional dose and volume of GTV are independent prognostic factors for the overall survival. The main death reasons are mucosa necrosis and/or massive hemorrhage in the nasopharynx.

OBJECTIVETo investigate the intra-vaginal ejaculation latency time (IELT) of varicocele patients, the influence of spermatic vein ligation on IELT, and the relationship of Visual Analogue Score (VAS) with IELT.

METHODSWe selected 112 males who had regular sexual life after spermatic vein ligation and conducted follow-up visits for 6 months. According to preoperative IELT, we divided the patients into an IELT < or = 2 min group and an IELT > 2 min group, and compared their IELT, VAS and Chinese Index of Sexual Function for Premature Ejaculation-5 (CIPE-5) scores before and 6 months after operation.

RESULTSFollow-up was accomplished in 81 of the patients, 18 in the IELT < or = 2 min group and 63 in the IELT >2 min group. Compared with the baseline, IELT was significantly prolonged postoperatively in both the IELT < or = 2 min group ([1.26 +/- 0.37] vs [4.53 +/- 1.69] min, P < 0.01) and the IELT >2 min group ([5.14 +/- 2.03] vs [7.69 +/- 4.51] min, P < 0.05); the postoperative CIPE-5 scores were remarkably improved in the former (11.27 +/- 3.52 vs 15.64 +/- 2.37, P < 0.05) but insignificantly in the latter group (20.42 +/- 4.65 vs 21.83 +/- 5.49, P > 0.05); the postoperative grades of the CIPE-5 scores showed significant differences in both groups (chi2 = 6.353, P = 0.042 and chi2 = 3.910, P = 0.048); the postoperative VAS was markedly increased (3.18 +/- 0.92 vs 1.56 +/- 0.83 and 3.24 +/- 0.95 vs 1.74 +/- 0.79, P < 0.05), with significant differences in the grades of VAS in both groups (chi2 = 4.433, P = 0.035 and chi2 = 10.088, P = 0.001). The variation of VAS was negatively correlated with that of IELT in both groups (r = -0.572, P < 0.01 and r = -0.465, P < 0.05).

CONCLUSIONVaricocele may be one of the causes of premature ejaculation, and some of the varicocele patients with IELT < or = 2 min may benefit from spermatic vein ligation. Improved VAS is negatively correlated with prolonged IELT. The relationship between varicocele and premature ejaculation deserves further studies.

Objective To explore the effects of forepaw sensorimotor deprivation in early life on hippocampus-dependent spatial reference learning and memory in rats. Methods Newborn SD rats were randomly assigned to experiment group (deprivation of forepaw sensorimotor function, n=53) and control group(n=55). Rats of postnatal day 13 (PN13) in experiment group were seleeted, and models of forepaw sensorimotor deprivation were established by microsurgical technique. Open field tests and Morris water maze tests were performed during the time periods of PN25(PN21-31), PN35 (PN31-39), PN45(PN41-50) and PN60(PN56-64) to evaluate the locomotor activity and spatial reference learning and memory, respectively. Results In open field tests, there was no significant difference in parameters of locomotor activity and exploratory behavior between the two groups (P>0.05). In Morris water maze tests, eontrol group performed significantly better than experiment group during training sessions and probe tests on PN25 and PN35 (P<0.05). While on PN45, although there was no significant difference between the two groups during training sessions, control group performed significantly better than experiment group during probe tests (P<0.05). Conclusion The deprivation of forepaw sensorimotor in early life has no signifieant effect on the locomotor activity and exploratory behavior of rats, but can impair the spatial reference learning and memory.

Objective To investigate the effects of television-watching and computer-using on sleep/wake patterns, sleep duration and sleep problems of school-aged children in Shanghai. Methods A total of 4 108 school-aged children from 10 primary schools of Shanghai were enrolled by multi-stage cluster sampling and surveyed by questionnaires. The information of television-watching and computer-using, family and personal condition was investigated by self-prepared questionnaire, and the Chinese version of Children's Sleep Habits Questionnaire was employed to survey the sleep behaviors of children. The effects of television-watching and computer-using on sleep/wake patterns, sleep duration and sleep problems were analyzed by multiple linear regression analysis and Logistic regression analysis. Results The percentage of children who watched television≥2 h per day was 4.1% during weekdays, and that came to 49.2% during weekends. In terms of frequency of computer-using, most children reported "rarely" (88.2%, 0-1 time/week), followed by "often" (11.0%, 2-4 times/ week) and "usually" (0.8%, 5-7 times/week). With the age increase, the percentages of children who watched television≥2 h per day and those who "often" used computer gradually increased. It was revealed by multiple linear regression analysis and Logistic regression analysis that television-watching and computer-using were not only positively correlated with later bedtime, later wake time and shorter sleep duration but also significantly associated with sleep problems such as bedtime resistance, sleep onset delay, sleep duration disorder, sleep anxiety and parasomnia. Conclusion Television-watching and computer-using exert influences on sleep behaviors of sleep/wake patterns, sleep duration and sleep problems. Concerns about the potential negative effects of television-watching and computer-using on sleep behaviors may help to promote healthy sleep patterns and improve sleep quality.
