Objective To investigate the correlation of traditional Chinese medicine (TCM) syndrome types of chronic gastritis with Helicobacter pylori (Hp) eradication rate after anti-Hp treatment. Methods A total of 180 chronic gastritis patients with Hp infection were differentiated into spleen-stomach insufficiency syndrome, spleen-stomach dampness-heat syndrome, and liver depression and qi stagnation syndrome, and each syndrome group had 60 cases. Patients in each group were evenly divided into two subtypes, and were treated with triple therapy or quadruple therapy for 10 days respectively. After treatment, the Hp eradication rate in each group was compared. Results (1) The overall Hp eradication rate was 78.3%. No matter after triple therapy or quadruple therapy, patients with spleen-stomach insufficiency syndrome had the lowest Hp eradication rate (61.7%), which was lower than that of the patients with spleen-stomach damp-heat syndrome (88.3%) and the patients with liver depression and qi stagnation syndrome (85.0%), the difference being statistical significance (P < 0.05 or P < 0.01). However, the difference of Hp eradication rate between spleen-stomach damp-heat group and liver depression and qi stagnation group was not statistically significant (P>0.05). (2) A total of 10 cases had adverse reaction such as nausea and vomiting, stomachache, and gastric distention, 8 cases from spleen-stomach insufficiency group, one from spleen-stomach dampness-heat group, and one from liver depression and qi stagnation group. Spleen-stomach insufficiency group had higher incidence of adverse reaction than the other two groups (P < 0.05). Conclusion The Hp eradication rate after anti-Hp treatment varied in chronic gastritis patients with different TCM syndrome types, and the rate in patients with spleen-stomach insufficiency syndrome was lower than that of the patients with spleen-stomach damp-heat syndrome and the patients with liver depression and qi stagnation syndrome no matter after triple therapy or quadruple therapy.

Objective Postictal language testing can provide useful diagnostic information for seizure lateralization.However no such a study based on non-English language was done previously.We investigated the latency of language recovery in Chinese patients with temporal lobe epilepsy (TLE).Methods Complex partial seizures in patients with TLE were extracted from our video-electroencephalogram (EEG) database.For all patients,consciousness testing started as soon as seizures were detected.When they were alert and cooperative,they were asked to read out a sentence “昨晚他们听到老在电台里讲话”which was printed on a card.When the patients were able to read the sentence correctly,the language function was considered recovered.Results Totally 65 complex partial seizures from 22 cases of TLE (11 left and 11 right) were included.Patients were cooperative to language testing in 54 seizures (83％).The latency for consciousness recovery (CRL) and latency for consciousness language recovery (LRL) were not associated with seizure duration,but the seizure lateralization.The CRL (median,161 s) and LRL (281 s) in the left TLE were statistically significantly longer than that in the right TLE (30 s,54 s respectively).Using 150 s recovery time as bound language recovery ratio was 87％ (27/31) in right TLE and 13％ (3/23) in left TLE.Conclusion Postictal language testing based on ideographic Chinese words helps to establish seizure lateralization in patients with TLE.

Objective:To explore the association between different urbanization levels and non-commu-nicable diseases (NCDs)in China and provide suggestions on designing relevant health policies in the ur-banization process.Methods:We obtained health-related data from China Health and Retirement Longi-tudinal Study (CHARLS)201 1 .This study used multistage sampling in design stage and covered 1 50 districts/counties,representative at the levels of the country.Geo-information system (GIS)method was used to get district areas data,and in combination with the Sixth National Census population data,we computed the population density which was regarded as the proxy variable of urbanization level in every city.The Logistic model was used to explore the effect of urbanization level on hypertension,diabetes, smoking,drinking,overweight and obesity.Results:Compared with other cities in China,Shanghai and Shenzhen,with the population density of more than 3 000 people per km2 ,were the cities with highest urbanization level.From the map of urbanization distribution across China,it was found that the urbani-zation levels of the northwestern districts were lower than those of the southeastern and coastal districts. The hypertension rate increased with the development of urbanization but there was no statistical signifi-cance.The proportion of patients with diabetes went up first and then saw a decrease trend in the process of urbanization.Drinking rate,overweight rate and obesity rate had similar trends,falling to their lowest point when urbanization level equaled 737,1 1 86 and 1 353 people per km2 respectively and then ex-perienced upward trends.By contrast,smoking rate declined first and then went up (the turning point was 1 029 people per km2 ).Conclusion:Different urbanization levels have different effects on NCDs, health-related behavior,overweight and obesity.Low urbanization level may create negative impact on health while high level can pose positive effect and increase people’s health condition possibly due to the improvement of health care accessibility and the quality of living environment.Policy-makers should spe-cially focus on different residents’health problems in different periods of urbanization,such as the impact of environmental pollution,health resources’allocation and accessibility of health services.It is necessa-ry to reduce or avoid the negative effect of urbanization on NCDs during the local development process to face the NCDs’threat.

Objective To explore the diagnostic value of post processing techniques of MSCT for diagnosing congenital heart disease associated with tracheobronchial stenosis in children. Methods Thirty four patients with congenital heart disease complicated by tracheobronchial stenosis were evaluated with MSCT. MPR, CPR, MinIP and VR were performed to show the tracheobronchial morphology. Findings in 43 segments of 32 cases were compared with the findings of surgical operation. Mann-Whitney test was employed to assess the significance of measurement between the post processing techniques and the operation. Results The lenghth of stenotic segments were variable seen at operation, with values between 4-39 mm in trachea, 4-33 mm in main bronchi and 3-12 mm in lobe bronchi, respectively. The biggest difference between the measurement of operation and MSCT was 4 mm (3 segments). Other differences ofstenotic segments were within 3 mm. Six segments exhibitee mild, 16 moderate and 21 severe stenosis at surgery. By contrast, five segments exhibited mild, 17 moderate and 21 severe stenosis by MPR or CPR,2 mild,9 moderate and 32 severe stenosis by MinIP and 4 mild, 11 moderate and 28 sever stenosis by VR,respectively. There was no significant difference in measuring the degree of tracheobronchial stenosis between MPR or CPR, VR and the surgery (Z =-0. 105,- 1. 479;P ＞0.05), while MinIP frequently overrated the degree of stenosis compared with the measurement at surgery (Z=-2.484,P =0. 013). Conclusion The integrated three dimensional reformations of MSCT scan can accurately evaluate the degree and extent of congenital heart disease associated with tracheobronchial stenosis in children and provide valuable information for clinical management.

Objective To investigate the difference of morphology and blood flow of cavopulmonary anastomosis by MRI and that by ultrasonic cardiography (UCG) in patients with bidirectional Glenn shunt (BGS).Methods Phase-contrast MRI (PC-MRI) and contrast enhanced MRI (CE-MRI) were performed for superior vena cava ( SVC ) and inferior vena cava (IVC) in 22 patients with BGS on 3.0 T MR scanner.PC-MRI was used for measuring blood flow and CE-MRI for illustrating morphology.The width,peak flow velocity and gradient pressure of cavopulmonary anastomosis were calculated by using Report Card software.The similar data of UCG was collected.The parameters by MRI and that by UCG were compared statistically by t test and Pearson correlation.Results Based on the MRI data,the blood flow of SVC [ ( 1.002 ±0.208) L/min ] was significantly lower than that of IVC [ ( 1.794 ± 0.392 ) L/min ] ( t =- 15.148,P ＜0.01 ),while the regurgitation fraction of SVC [ (26.54 ± 12.82)％ ] was significantly higher than that ofIVC [ ( 17.44 ± 10.17)％ ] (t =11.060,P ＜0.01 ).The morphology displayed with MRI angiography couldnot be detected with UCG.The width of cavopulmonary anastomosis measured by MRI [ (12.46 ±3.43 ) mm ] was significantly higher than that of UCG[ ( 11.04 ± 2.63 ) mm] ( t =4.048,P ＜ 0.01 ),while the peak flow velocity of cavopulmonary anastomosis measured by MRI [ (47.77 ± 10.44) cm/s] was significantly lower than that of UCG [ (52.19 + 9.63) cm/s] ( t =- 2.237,P ＜ 0.05 ).No significant difference was found in gradient pressure of cavopulmonary anastomosis between the values by MRI [(0.95+0.42) mm Hg(1 mm Hg =0.133 kPa)] and that by UCG [(1.12+0.38)mm Hg] (t=2.010,P ＞ 0.05).The width,peak flow velocity and gradient pressure of cavopulmonary anastomosis by MRI were closely correlated with those by UCG (r =0.858,0.489,0.427,all P＜ 0.05 ).Conclusions A good correlation is found in the width,peak flow velocity,and gradient pressure of the cavopulmonary anastomosis obtained by 3.0 T MRI and UCG.MRI is more useful tool to display the width and abnormal morphology of cavopulmonary anastomosis than UCG.

Objective To investigate the relationships of suicide risk and its associated risk factors in adult patients with epilepsy.Methods All 211 adult patients with epilepsy from the epilepsy clinic of the Second Affiliated Hospital,Zhejiang University School of Medicine,were enrolled to evaluate the presence of suicide risk and depressive disorder by using the suicide module and the depressive disorder module of the Mini International Neuropsychiatric Interview (MINI).Demographic variables for age,gender,employment status,marital status,years of education,and seizure factors for age of onset,types of seizure,seizure frequency and epilepsy duration,result of MRI and types of antiepileptic drugs were also recorded.We compared the differences of risk factors between the two groups with or without suicide risk and investigated the relationships between the depressive disorder and suicide risk.Results The suicide risk of the patients was 21.3％ (45/211),and 17.1％ (36/211) of the patients had depressive disorder.The suicide risk of the epilepsy patients associated with depressive disorder was 75.0％ (27/36),and the suicide risk of the epilepsy patients associated with no depressive disorder was 10.3％ (18/175).There was statistical difference between the two groups (x2 =74.525,P ＜ 0.01).About 60.0％ (27/45) of the patients with suicide risk was accompanied with depressive disorder.As suicide risk increased,the proportion of concurrent depressive disorder elevated.There was significant statistical difference in the rates of depressive disorder among the different suicide risk groups.Conclusions The patients with epilepsy have suicide risk.The suicide risk is higher in patients with depressive disorder.

Objective To explore the safety of total thyroidectomy surgery on patients with thyroid carcinoma. Methods From Jan 1986 to Dee 2006, clinical data of patients who underwent total thyroidectomy (total thyroidectomy group) and sub-total or near-total thyroidectomy surgery (control group) for thyroid carcinoma were retrospectively analyzed to identify the incidences of complications, recurrent laryngeal nerve paralysis (RNLP) and secondary hypoparathyroidism in the two groups. Results In the control group there were 433 thyroid carcinoma patients who underwent sub-total or near-total thyroidectomy. Transient unilateral RLNP(13 eases), permanent unilateral RLNP(5 eases), transient hypoparathyroidism (11 cases) was diagnosed. There was no permanent hypoparathyroidism in this group. In the 70 cases of thyroid carcinoma patients receiving total thyroidectomy, there were 4 eases suffering from transient unilateral RLNP, one case from permanent unilateral RLNP (P > 0.05), and there were 7 eases from transient hopyparathyroidim (P < 0.01), 2 eases from permanent hypoparathyroidism (P < 0.05). Conclusion The incidence of RLNP after total thyroidectomy was not higher than that after subtotal or near-total thyroideetomy. Postoperative hypocalcaemia was the most common postoperative complication of total thyroidectomy. It is our belief that total thyroidectomy should be performed in selected patients.
