Vitamin is necessary and important for humans and an-imals to maintain normal physiological function, metabolism, and growth. The studies suggest that vitamin is one of the factors which play a role in the activity of enzymes, and it is coenzyme of many enzyme or an important component of coenzyme. The lack of vitamins causes a metabolic vitamin deficiency. Pharma-cogenomics research the relationship between human genetic vari-ation and drug reaction, using the information to solve the differ-ent reactions among the different individuals of the same drug. Vitamins, which constitute human tissues and maintain normal physiological functions, are also an important part for the phar-macogenomics study.

Objective To provide guidance for clinical prevention and treatment of bleeding during percutaneous nephrolithotomy( PC-NL) . Methods The clinical data of 1 012 patients with intraoperative and postoperative bleeding during percutaneous nephrolithotomy in our urology department were collected,hemorrhoea occurred on 36 cases,the occurrence rate was 3. 56%. The incidence,correlation with cal-culi,diabetes mellitus,examination item,technical operation were analyzed and compared. Results The incidence was 5. 52% for patients with complicated calculi. The incidence of delayed massive haemorrhage has been increased postoperatively in the diabetes mellitus patients. This incidence was 1. 81% for patients with preoperative examination. Along with the extension of time in carrying out technology,PCNL asso-ciated bleeding incidence decreased year by year. Conclusion The occurrence of haemorrhage associated with PCNL could be decreased by correctly handling complicated calculi,preoperative examination,keeping blood glucose homeostasis and improving the manipulation ability of operator.

ObjectiveTo investigate the significance of cerebrospinal fluid(CSF) S-100B protein and vascular endothelial growth factor (VEGF) levels in the pathogenesis of brain injury of viral encephalitis.MethodsForty-two patients with viral encephalitis (viral encephalitis group) and 40 patients with other disease at the corresponding time period(control group) were involved in this study.CSF (routine,biochemistry and cytology) was detected,and the levels of S-100B protein and VEGF in CSF were detected by ABC-ELISA method.ResultsWhite blood cell count was (0-584) × 106/L in viral encephalitis group,and (0-200) × 106/L in control group.The levels of protein and glucose in CSF had no significant difference between two groups (P＞ 0.05),and the level of chloride in CSF in viral encephalitis group was significantly lower than that in control group[ ( 110.10 ± 31.22 ) mmol/L vs.( 123.80 ± 6.32 ) mmol/L ] (P =0.006).In viral encephalitis group,cytological examination showed that mixed type cytological reaction was in 6 cases (14.3％,6/42).The level of S-100B protein in viral encephalitis group [25.04-47.97 (28.37 ± 6.09) ng/L] was significantly higher than that in control group[ 25.04-29.64(26.03 ± 0.90) ng/L ] (t =2.462,P =0.018).The level of VEGF in viral encephalitis group[88.84～143.77(96.24 ± 13.38) ng/L] was significantly higher than that in control group [89.15～96.18 (90.67 ± 1.71 ) ng/L] (t =2.673,P =0.011 ).ConclusionsThe high levels of S-100B protein and VEGF in CSF could support the viral encephalitis diagnosis.Tracking the levels of S-100B protein and VEGF in CSF dynamically have noticeable effect on checking the condition of viral encephalitis patients.

ObjectiveReport an operation of off-pump occlusion of trans-thoracic minimal invasive surgery (OPOTTMIS) adopted on the therapy of 92 patients suffered with simple congenital heart diseases (CHD) of atrial septal defect ( ASD),ventricular septal defect ( VSD ) and patent ductus arteriosus (PDA) and summarize the experiences.Methods The clinical data of 92 CHD patients administrated with OPOTTMIS in our hospital during the time of July 2008 and July 2011 were analyzed retrospectively.Moreover,the relevant literatures were reviewed and the different kinds of treatments and their outcomes of CHD were compared.These patients were 3-56 years old and weighed 8.0-54.5 kg,with male and female 38 and 54 cases,including ASD 52 cases,VSD 26 cases and PDA 14 cases,respectively.Within the initial 3 months of postoperation,all the patients were followed up and managed to take the re-examination with electrocardiogram and echocardiogram one time for each month,and 3 months later,at least one time for every 3-6 months.Results91 cases were performed the OPTTMIS procedure successfully,1 child with sieve-like ASD transferred to open-heart surgery and 1 adult( 1.1％ ) PDA died on the second day after operation for the pulmonary hypertension crisis.4 cases appeared mild residual shunt including 2 of ASD,1 of VSD and 1 of PDA.2 cases showed Ⅱ stage atrial ventricular block ( AVB ) within ASD and VSD,respectively.Also,post-operation hemothorax happened to 1 case ASD and 1 case VSD for the active bleeding of cardiac puncture site and the exploration and hemostatic operation were performed.91 (98.9％) patients were performed the OPOTTMIS operation successfully,the total complications within 72 hours was 6.5％ (6/92),respectively.There were no heavy complications happened during peri-operation such as cardiac rupture,infective endocarditis,stroke,hemolytic and thrombus formation.90 patients outcomes of 3 months to 4 years follow-up with the ECG and UCG examination showed that there were no Ⅲ stage atrioventricular block,no obvious occluder shift and broken and no moderate cardiac valve regurgitation,no evident blood flow restriction of left ventricular outflow tract and descending aorta,only found mild residual shunt within 2 cases ( VSD and PDA each) and heart expansion compared to pre-operation within 2 PDA patients.However,all the patients'heart functions were in grade Ⅰ to grade Ⅱ according to NYHA standard.ConclusionOPOTTMIS is a safe,feasible and effective option on simple congenital heart diseases.

Objective To establish a modified dynamic 99Tcm-pertechnetate salivary gland scintigraphy(SGS) method,and to evaluate the value in the diagnosis of Sj(o)gren's syndrome(SS) by comparing SGS with labial gland biopsy (LGB).Methods A total of 204 patients (21 males,183 females,age range 20-85 years) with suspected SS who underwent the modified dynamic SGS and LGB were enrolled in this prospective study.Uptake ratio (UR) and excretion fraction (EF) of the left parotid gland (LPG),the right parotid gland (RPG),the left submandibular gland (LSG) and the right submandibular gland (RSG)were calculated.Two-sample t test was used for data analysis.The sensitivity,specificity,accuracy of the modified dynamic SGS and LGB were calculated,and x2 test was used for data analysis.Results SS was confirmed in 113 patients,including 79 patients with primary SS and 34 patients with secondary SS.SS was excluded in 88 patients.The UR and EF of the SS group (LPG:1.95±1.04 and (52.2±19.5)％,RPG:1.96±1.06 and (55.0±21.1)％,LSG:2.65±1.12 and (25.9±14.1)％,RSG:2.72±1.30 and (29.7± 14.7) ％) were significantly lower than those of the non-SS group (LPG:3.08± 1.10 and (65.9± 12.7) ％,RPG:3.26±1.16 and (66.4±12.6)％,LSG:3.71±1.31 and (43.2±12.3)％,RSG:3.74±1.39 and (46.6± 11.5) ％;t=4.40-9.00,all P＜0.05).The sensitivity,specificity,accuracy of the modified dynamic SGS were 99.1％ (112/113),72.7％ (64/88),87.6％ (176/201),respectively,while those of LGB were 83.2％ (94/113),96.6％ (85/88),89.1％ (179/201),respectively.The sensitivity and specificity of SGS method were significantly different from those of LGB (x2 =15.9,17.5,both P＜0.05).Conclusions The modified dynamic SGS can reduce the acquisition time and has a high sensitivity for SS.When combined with LGB,it will improve the diagnostic accuracy for SS.

Objective To study the correlation between individual gene polymorphisms of transforming growth factor (TGF)-β1 + 869 T/C,tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) + 1525 G/A genes and nodular thyroid disease.Methods From September 2007 to December 2009,a total of 544 patients with nodular thyroid disease diagnosed in the Department of Endocrinology,The First Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology were selected,including 136 cases of nodular goiter patients (node group),132 cases of thyroid tumor (adenoma group),146 cases of Graves patients (GD group),and 130 cases of Hashimoto's thyroiditis (HT group).One hundred and thirty-five healthy subjects were enrolled as control group.Two milliliters of fasting venous blood of all subjects were collected.Polymorphisms of the TGF-β1 + 869 T/C and the TRAIL 1525 A/G genes were identified by the polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and the restriction fragment length polymorphism (PCR-RFLP) methods.Results TGF-β1 + 869 T/C:The CC genotypes and C allele frequencies of nodular goiter group [47.0％(64/136),63.2％(172/ 272)] were significantly higher than those of normal control group [18.0％(22/135),45.2％ (122/270); x2 =30.76,17.79,all P ＜ 0.05].The genotypes and allele frequencies of adenoma group[42.4％ (56/132),59.1％ (156/264)] were significantly higher than those of the normal control group (x2 =24.40,10.34,all P ＜ 0.05).The risk of population carrying the C allele suffering from nodular goiter was 2.086 times of those carrying the T allele (OR =2.086; 95％ CI:1.480-2.943).The risk of population carrying the C allele suffering from adenoma was 1.752 times of those carrying the T allele (OR =1.752,95％ CI:1.244-2.469).TRAIL + 1525 G/A:the genotypes and allele frequencies of nodular goiter group [40.4％ (55/136),62.9％ (171/272)] were significantly higher than those of normal control group [12.0％ (16/135),48.5％ (131/270); x2 =9.176,11.307,all P ＜ 0.05].The genotypes and allele frequencies of adenoma group[53.3％ (70/132),73.1％ (193/264)] were significantly higher than those of the normal control group (x2 =9.806,33.82,all P ＜ 0.05).The risk of population carrying the G allele suffering from nodular goiter was 1.796 times of those carrying the A allele (OR =1.796,95％ CI:1.275-2.531).The risk of population carrying the G allele suffering from adenoma was 2.884 times of those carrying the A allele (OR =2.884,95％ CI:2.009-4.142).Conclusions TGF-β1 + 869 T/C and TRAIL + 1525 G/A gene polymorphisms may be related to the incidence of nodular thyroid diseases; G allele of TRAIL and C allele of TGF-β1 may be predisposing genes of patients with nodular goiter.

Objective To evaluate transport efficiency and safety by process management during the handover of patients with tracheal intubation post-operation. Methods Prospective studies were performed between patients with or without process management during the handover. The time of handover were recorded and compared. The difference between systolic and diastolic blood pressure, heart rate, and arterial oxygen saturation were also recorded and compared. The adverse events during the handover were also investigated. Results It costed less time in the handover of patients under process management with significant difference[(4.75±0.54) min vs. (7.05±0.88) min, t=-17.21, P<0.01]. The incidence rate of harmful cases in the handover of patients under process management was significantly declined than that without process management[ 1.67%(1/60) vs. 13.33%(8/60),Χ2=4.324 3,P<0.05 ]. Conclusions Process management may facilitate the handover of patients with tracheal intubation post-operation and improve its safety.
