Purpose:To observe the curative effect and the clinical-benefit-response of patients with advanced pancreatic cancer who used a combine of Gemcitabine,5-FU and PDD.Methods:The treatment with Gemcitabine (800 mg/m 2) was followed by 5-FU(600 mg/m 2) and DDP (30 mg/m 2),administered on days 1,8 and 15 of 28-day schedule. The curative effect was estimated according to the standard of WHO and the clinical benefit response was evaluated at the same time. The standard of CBR included pain,physical states and body weight. Results:Twenty-five (25/29) patients received over two cycles chemotherapy. 6(24%) partial response (PR), 12 (48%) stable disease and 7(28%) progressive disease were observed. According to the standard of CBR, 18(62.1%) patients achieved the clinical-benefit-response level. Therapy was well tolerated. The main toxicities included that the alimentary tract reactions and the marrow depression. Grade 3-4 thrombocytopenia was reported in 8 (27.6%) patients. Conclusions:The combination of GEM, 5-FU and DDP is a moderatedly active treatment with tolerable side-effects. It has definite response rate and high CBR rate in pancreatic cancer.

Objective To study the expressions of CD24 and SLeX in lung cancer tissues,and evaluate the relation ship with development and progression of lung cancer.Methods Immunohistochemistry was used to detect the expressions of CD24 and SLeX in 70 specimens of lung cancer.Results The positive expression rates of CD24,SLeX in non-small cell lung cancer tissues were 41.3% and 63.5% respectively,There were no expression and weak expression respectively in small cell lung cancer (SCLC) tissues. The positive rates of CD24,SLeX in adenocarcinoma were 55.9% and 76.5%,respectively,which were higher than those in squamous cell carcinoma (24.1%,48.3%)(P0.05).In lung adenocarcinoma and squamous cell carcinoma,the positive expression rate of SLeX in stage Ⅲ (83.3%) was higher than that in stage Ⅰ-Ⅱ (55.6%),the positive rate in poor differentiated lung cancer(80.8%) was higher than those in moderate and well differentiate cancer(51.4%),the positive rate in female patients (76.7%) was higher than that in male patients (51.5%)(all P

34 medical college students and 26 patients with primary hypertension were served as the subjects on low sodium salt diet for 4 weeks. Before and after the experiment, serum and urinary sodium and potassium, as well as blood presure, pulse rate, and body weight were measured. During the testing period, calorie and protein were supplied sufficiently and the salt content in their common diet taken was restricted strictly. The results showed that the serum sodium decreased, potassium increased at the end of the experiment, but the changes were all within the physiological permissible limits. On the contrary, urinary sodium increased, potassium decreased and the Na/K dropped markedly, body weight increased slightly in healthy subjects and decreased by 1.0-3.0kg in patients with hypertension. The blood pressure, both systolic and diastolic, was decreased but no change in the pulse rate was observed.It was obvious that in the subjects on common salt diet, the body sodium was high and potassium low, otherwise on low sodium salt diet, such situation might be improved, and the high blood pressure could also be ameliorated in the type Ⅰ and Ⅱ of hypertension.

Objective To investigate the effect factors for language and memory dominance testing in propofol Wada test in refractory epilepsy patients.Methods From January 2010 to August 2013,total of 23 patients underwent propofol Wada tests for language and memory dominance evaluation.According the performance in language test and memory test,the patients were divided into two groups,respectively:succeed with test or failed in test.The relevant factors including age,duration of epilepsy,handedness,FIQ (full scale of intelligence quotient),lateralization of lesions,language dominance,dose of propofol and the adverse effects of propofol were recorded as independent variables.Logistic regression was adopted to screen the effect factors for memory dominance evaluation.All statistical analyses were processed with SPSS software.Results All 23 patients succeeded with language test,but only 13 patients succeed with memory test.The difference of success ratios between language test and memory test was significant (P=0.001).For memory test,the difference of duration of epilepsy and FIQ in success group and failed group was significantly different (duration of epilepsy:(10.57±4.68) vs (18.30±9.30),P=0.032,FIQ:(81 ±25.33) vs (64.2±10.86),P=0.046).More grade Ⅱ adverse effects of propofol occured in the patients who failed in memory test (P=0.011).Logistic regression results indicated the grade Ⅱ adverse effects of propofol were the main risk factor for memory test failure (OR=28.0,P＜0.01).Conclusions Propofol Wada test is an effective method for language dominance evaluation.However,the effect factors for memory dominance evaluation are much more than language evaluation,such as duration of epilepsy,FIQ and grade Ⅱ adverse effects of propofol,and grade Ⅱ adverse effects of propofol may be the most significant risk factor.

Objective:To analyze the associations between attention deficit hyperactivity disorder (ADHD) and serum vitamin B levels in children.Methods:A total of 103 ADHD children who were diagnosed in the Department of Child and Adolescent Healthcare of Children′s Hospital of Soochow University from September 2018 to April 2019 were selected as the ADHD group, and 89 children of the same age who underwent routine physical examinations served as the healthy control group.The serum levels of vitamin B, including vitamin B 1, vitamin B 2, vitamin B 6, vitamin B 9, and vitamin B 12, were measured by the methods of electrochemistry.Weiss Functional Impairment Rating Scale-Parent Report (WFIRS-P) was applied to analyze the correlation between social function scores and vitamin B levels in ADHD children. Results:The levels of vitamin B 9[(12.55±2.22) nmol/L vs.(13.26±2.54) nmol/L] and vitamin B 12 [(278.54±32.00) ng/L vs.(288.90±31.32) ng/L] in ADHD children were significantly lower than those in healthy children( t=-2.064, -2.261, all P<0.05). No significant difference was observed in serum levels of vitamin B 1, vitamin B 2 and vitamin B 6 between the 2 groups (all P>0.05). Correlation analysis displayed that only vitamin B 12 level was significantly and negatively correlated with social function in the learning/school dimension ( r=-0.208, P=0.035), and no significant correlation was found between other vitamin B levels and social function (all P>0.05). Conclusions:The serum levels of vitamin B 9 and B 12 in ADHD children were obviously lower than those in healthy children of the same age.Serum vitamin B 12 deficiency had an influence on the social function of the learning/school in ADHD children.Attention to the monitoring and timely supplementation of vitamin B in childhood, especially vitamin B 9 and B 12, may be of positive significance in the prevention of the occurrence and development of ADHD to some extent.

Objective:To study the effects of expansion of ropivacaine hydrochloride liquid on the postoperative analgesia,sedation, hemodynamic effects and adverse drug reactions of the patients underwent endoscopic thyroidectomy,and to explore its clinical effectiveness and safety. Methods:Forty patients who were to undergo endoscopic thyroidectomy via chest-breast approach were randomly assigned to saline solution group and expansion liquid of ropivacine hydrochloride group (ropivacaine group,n = 20).The mean arterial pressure (MAP )and heart rate (HR)were also evaluated at the following time points:preoperative evaluation (T0 ),before local anesthetic infiltration (T1 ),at the end of the operation (T2 );the blood loss,the operation time,the postoperative drainage,and the hospital duration of the patients in two groups were recorded; the nausea and vomiting,the respiratory depression,the toxicity response,the infection,and the recurrent laryngeal nerve injury during 24 h after operation were recorded.The postoperative pain scores were assessed at extubaltion (T3 ),30 min (T4 ),2 h (T5 ),6 h (T6 ),12 h (T7 )and 24 h (T8 )after extubation using Visual Analog Scale (VAS).The postoperative Ramsay scores were assessed at T3 and T4 .Results:There were no significant differences in MAP and HR at T0 and T1 of the patients between two groups (P >0.05).Compared with saline solution group,the MAP and HR at T2 and T3 of the patients in ropivacaine group were significantly decreased (P < 0.05).There were significant differences in the blood loss,the operation time, the postoperative drainage,and the hospital duration of the patients between two groups (P <0.05).The number of patients required postoperative analgesia and the number patients with nausea and vomiting in ropivacaine group were decreased compared with saline solution group (P <0.05).Compared with saline group,the VAS scores at T3 ,T4 ,T5 ,T6 ,T7 and T8 of the patients in ropivacaine group were significantly decreased (P <0.05);the Ramsay scores at T3 and T4 of the patients in ropivacaine group were also decreased significantly (P <0.05).Conclusion:Expansion liquid of ropivacaine hydrochloride can reduce the stress response during endoscopic thyroidectomy effectively and reduce the postoperative pain and injury induced by operation.

Conclusion After discharges monitoring improve the accuracy, reduce the risk of intraoperative cerebral cortex electrical stimulation.

Objective To reduce the screening positive rate (SPR) and improve clinical efficiency of maternal serum screening for Down's syndrome.Methods Nine thousand and thirty-three cases of second trimester maternal serum screening for Down's syndrome were included from Apr.2013 to Apr.2014 in the present study.The screening results,all basic data and equation curves were analyzed retrospectively.Based on the data from the authors' laboratory,the important adjustment parameters were simulated.Combined with postnatal follow-up results,the quality and clinical performance of second trimester serum screening for Down's syndrome were evaluated.Results The SPR of second trimester serum screening for Down's syndrome was 6.69％(604/9033),the detection rate (DR) was 75％(3/4),and FPR was 6.65％(601/9033).The median multiple of median (MOM) of alpha-fetoprotein (AFP) was low and SPR was high,and MOM of free human chorionic gonadotropin β subunit (free hCGβ) were high and SPR was high,while MOM of unconjugated estriol (uE3) were a little bit low,and SPR was slightly high.Considering these three factors,it is believed that the screening positive rate is high.By the simulation adjustments of MOM value equations (AFP and free hCGβ) and weight correction equation,the SPR reduced to 4.11％(371/9033) after recalculating the risk,FPR declined to 4.07％(368/9033),and no more Down's syndrome fetus were missed compared with postnatal follow-up results.Conclusion Based on a localized setting depending on the local laboratory data,we suggest that the MOM value distributions(AFP,free hCGβ and uE3) and maternal weight should be regularly adjusted since it is a useful way to reduce the false-positive rate and improve clinical efficiency of maternal serum screening for Down's syndrome.

Obesity is a chronic nutritional disease caused by excessive energy intake greater than energy consumption.Obesity has become a serious global health problem not only in Chinese adults but also in children.The prevention and treatment of obese children and adolescents has become a hot spot in the health field.It is still the first choice for obese children and adolescents to lose weight by changing lifestyle which including nutrtion intervention,exercise intervention and behavioral intervention and carrying out nutrition intervention reasonably.Over the past decade,a large number of clinical trials and animal experiments have achieved remarkable results on losing weight and the rate of complications in children and adolescents.Here we review progress of dietary intervention which including nutrients and diet patterns in obese children and adolescents.

Objective Introduce a technique for creating 3-dimensional (3D) brain models of subdural electrodes , ideal for demonstrating the space-relationship of seizure localization and eloquent cortices , and discuss its usefulness for presurgical evaluation of epileptic patients. Methods Patients with medically intractable epilepsy were underwent a thorough preoperative MR brain scan including a T1-weighted high-resolution 3D sequence. Intraoperative photographs were taken with the digital camera. After the surgical implantation of subdural electrodes for epileptic zone localization , the thin-slice CT scan of the electrodes were taken and coregistered to preoperative brain 3D MR images in the Medtronic StealthMerge software environment. After the iEEG monitoring , multiple habitual seizures were recorded , eloquent areas were also identified by electrical stimulation of the cortex. The epileptic zone and the eloquent areas were marked on the subdural electrodes respectively. Then, 3D tessellations of the epileptic zone and the eloquent areas were rendered. Results Six patients (4 male, 2 female) were enrolled in this study. The mean time of iEEG monitoring was 13.7 days. After the coregistration of postoperative CT with preoperative 3D MRI , the 3D stereoscopic reconstruction provided an accurate representation of the implanted electrodes with highly detailed visualization of the underlying anatomy. The visual comparison between 3D reconstructions and intraoperative photographs indicated a good correspondence. The patients were followed for 3 to 6 months after the secondary operation , and had continuing improvement in seizure control. Conclusions The results indicate that the 3D reconstruction of subdural electrodes can reveal the precise localization of subdural electrodes , and can be useful for the presurgical evaluation of epileptic patients.
