BACKGROUND:Acute exercise is believed to regulate appetite and influence feeding behaviors by controling the synthesis and secretion of gastrointestinal peptide hormones to regulate appetite and feeding behavior influence, but the smal sample size leads to widely different results.
OBJECTIVE:To clarify the effect of acute exercise on peptide YY levels in adults using Meta-analysis method. METHODS:A computer-based search of PubMed, Google Scholar, Sport Discus, Web of Knowledge and CNKI was performed for relevant articles published before January 2014. The literatures eligible were studied by evaluating the publication bias, checking the heterogeneity and analyzing the sensitivity by software of RevMan5.1.
RESULTS AND CONCLUSION:(1) There were a total of 188 participants in the 18 trials reported in 11 articles. The Meta-analysis results revealed a mean effect for acute exercise to increase peptide YY values (standardized mean difference=0.25, 95% confidence interval =0.05-0.46,P=0.01), and therefore, there was a significantly statistical difference in the peptide YY levels between the acute exercise group and control group (P< 0.05). Moreover, results from the sensitivity analysis showed no influences on the findings of Meta-analysis. (2) Five randomized controled trails in the three included articles were related to peptide YY (3-36). There was a maximal heterogeneity among these studies; therefore, a random-effect model was utilized. The result revealed a mean effect for acute exercise to increase peptide YY (3-36) values (standardized mean difference =1.80, 95% confidence interval =0.27-3.32,P=0.02). The findings from this meta-analysis show that acute exercise may influence appetite by increasing levels of peptide YY in adults.

Objective To analyze the association between interleukin-23 receptor (IL23R) gene single nucleotide polymorphisms (SNPs) and multiple sclerosis (MS) in a Southern Han Chinese population.Methods Three SNPs (rs2201841,rs10889677,rs7517847) within the IL23R gene were detected in 178 MS patients and 221 controls using polymerase chain reaction and restriction fragment length polymorphism method (PCR-RFLP).Haplotypes of the IL23R gene were constructed with SHEsis software.Results The frequencies of the genotype or allele in the IL23R gene SNPs(rs2201841:TT,TC,CC in MS patients:5.7％ (10/175),45.7％ (80/175),48.6％ (85/175),in controls:7.4％ (16/217),41.0％ (89/217),51.6％ (112/217),x2 =1.08,P =0.58 ; rs10889677:AA,AC,CC in MS patients:52.0％ (89/171),42.7％ (73/171),5.3％ (9/171),in controls:57.7％ (123/213),36.2％ (77/213),6.1％ (13/213),x2 =1.71,P =0.43 ; rs7517847:GG,GT,TT in MS patients:16.9％ (29/172),51.7％(89/172),31.4％ (54/172),in controls:14.4％ (31/215),49.3％ (106/215),36.3％(78/215),x2=1.15,P =0.56)showed no significant difference between MS patients and controls.The genotype did not influence the age of onset,the duration or disease severity in MS patients.The SNPs rs2201841 and rs10889677 had strong linkage disequlibrium (D' =0.614,r2 =0.327).The haplotype frequencies showed no significant difference between the MS patients and controls.Conclusion There is no evidence in our study to support the association between IL23R SNPs and MS in a Southern Han Chinese population.

Objective To identify the risk factors for early postoperative cognitive dysfunction (POCD) in the elderly patients undergoing spinal surgery.Methods One hundred and fifty ASA Ⅱ or Ⅲ patients,aged ≥65 yr,undergoing elective spinal surgery under general anesthesia,were studied.Venous blood samples were taken at 1 day before operation and 7 days after operation to determine the concentration of serum S-100B protein.Cognitive function was assessed by Mini-Mental State Examination (MMSE) at 1 day before operation and 7 days after operation.The patients were diagnosed as having POCD if MMSEpre-MMSEpost ≥ 3.The patients were divided into POCD group and non-POCD group.Age,body weight,sex,education,type of operations,complications,preoperative TCM syndrome type,MMSE score at 1 day before operation and 7 days after operation,duration of operation,emergence time,and intraoperative blood loss,cardiovascular events,and amount of fluid infused per hour were recorded.The risk factors for POCD were analyzed using multivariate logistic regression analysis.Results Thirty-eight patients developed early POCD (25.3％).The resuhs of logistic regression analysis showed that age ≥ 70 yr,elementary education or below,duration of operation ≥5 b,and the number of hypotension occurred during operation≥3 were the risk factors for early POCD.Conclusion Age≥70 yr,elementary education or below,duration of operation ≥ 5 h,and the number of hypotension occurred during operation ≥ 3 are the risk factors for early POCD in the elderly patients undergoing spinal surgery.

Objective: To explore the effect of single-nostril transsphenoidal approach on pituitary adenoma. Methods: We retrospectively analyzed 46 cases of pituitary tumors treated with single-nostril transsphenoidal approach and the effects and complications of surgery.Dunng the surgery,a nasal speculum was inserted through right nostril slowly towards the anterior wall of sphenoid sinus.A nasal mucosa incision of about 1.5cm was made in the right nasal cavity at the level of the middle nasal turbinate.With a fracture of the bony septum,a space was developed between the bilateral nasal mucosa and bony septum to the sphenoid sinus.Then,the face of the sphenoid sinus was exposed.The remainder of the bony septum,the anterior sphenoid sinus wall,and the sphenoid mucosa were removed.The antenor sphenoidotomy should be less than 1.5cm wide.After confirming the tumor by dural puncture,a cross incision of dura was made and the tumor was removed.The saddle was usually Collapsed and visible after total tumor removal.When the tumor was resected,sevaral gelatin sponges were stuffed into the Surgical cavity to stop bleeding. Results: Thirty-four cases had total resection and 12 cases had subtotal resection.No deaths or disability occurred.Hormone levels in almost all patients were improved.Seventeen cases had a sign of diabetes insipidus.Electrolyte disturbance occuwed in 5 cases.NO postoperative cerebrospinal fluid rhinorrhea was observed. Conclusion: Single-nostril transsphenoidal approach has many advantages in treating pituitary adenomas such as simplified approach,brief technology and high security.

Objective To discuss the diagnosis and treatment of cerebral sparganosis. Methods To summary four cases of cerebral sparganosis, focusing on the clinical course and imaging findings, with the goal of better diagnostic skills. Results All 4 cases had some kind of misdiagnosis and improvement after surgery or parasiticidal pharmacotherapy. Cerebral MRI and CT scans revealed relatively extensive white matter degeneration and focal enhancements. Subsequent scans showed changes in shape and location of the enhanced foci, indicating the migration of sparganum. Pathologic findings of 3 patients who had undergone surgery showed granuloma and sparganum. Conclusions Cerebral sparganosis has relatively special manifestions on imaging, which are of diagnostic value. The spaganum should be as completely removed as possible during surgery.

Objective To evaluate the effects of long?term glucocorticoid administration on cisatra?curium?induced neuromuscular blockade in the patients undergoing laparoscopic operation. Methods Six?ty?four patients of both sexes, aged 40-64 yr, with body mass index of 18-22 kg∕m2 , of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, scheduled for elective laparoscopic operation under general anesthesia, were assigned into 4 groups ( n=16 each) according to whether or not glucocorticoid was used for a long?term period: control ( non?hormone and non?laparoscopic operation ) group ( group C ) , hor?mone + laparoscopic operation group ( group HL ) , non?hormone + laparoscopic operation group ( group NHL) and hormone +non?laparoscopic operation group ( group HNL) . Midazolam 0.03 mg∕kg was injected intravenously, 8% sevoflurane was inhaled by mask, and the concentration of sevoflurane was decreased by 2% every 30 s until the concentration of 4% was reached. After loss of eyelash reflex, remifentanil 2μg∕kg was injected intravenously over 1 min, and 30 s later sevoflurane inhalation was stopped. The patients were tracheally intubated and mechanically ventilated. Anesthesia was maintained with propofol and remifentanil given by target?controlled infusion. Neuromuscular blockade was monitored with accelerograph TOF?watch
SX. At 20 min of pneumoperitoneum in NHL and HL groups or 20 min after intubation in C and HNL groups, cisatracurium 0. 15 mg∕kg was injected intravenously. The onset time, maximal degree of N?M block, clinical duration and recovery index of cisatracurium were recorded. Results Compared with group C, the onset time was significantly prolonged, the maximal degree of N?M block was decreased, the clini?cal duration was shortened, and the recovery index was decreased in HL and HNL groups ( P<0.05) , and the clinical duration was significantly prolonged, the recovery index was increased ( P<0.05) , and no sig?nificant change was found in the onset time in group NHL ( P>0.05) . Compared with group HNL, the clin?ical duration was significantly prolonged, the recovery index was increased (P<0.05), and no significant change was found in the onset time in group HL ( P>0.05) , and the onset time was significantly shortened, the clinical duration was prolonged, and the recovery index was increased in group NHL ( P<0.05) . Com?pared with group NHL, the onset time was significantly prolonged, the maximal degree of N?M block was decreased, the clinical duration was shortened, and the recovery index was decreased in group HL ( P<0.05) . Conclusion Long?term glucocorticoid administration can weaken cisatracurium?induced neuromus?cular blockade in the patients undergoing laparoscopic operation.

Objective To investigate the effects of long-term glucocorticoid administration on neuromuscular block of cisatracurium in elderly patients undergoing general anesthesia. Methods Forty ASA Ⅱ or Ⅲ patients,aged≥65 yr,with BMI of 18-24 kg/m2 ,scheduled for elec-tive operation were studied.According to the history of using or not long-term glucocorticoid,patients were assigned into two groups (n = 20 each):control group(group C),glucocorticoid group(group J).Midazolam 0.03 mg/kg was injected,mask inhalation of 8% sevoflurane and flow rate of oxygen 8L,every 30 s decline 2%,until the 4%.After the disappearance of eyelash reflex,cisatracurium 0.1 5 mg/kg was injected intravenously.After 1 min intravenous injection of remifentanil 2 g/kg and 30 s after stop of sevoflurane inhalation anesthesia, endotracheal intubation for mechanical ventilation,target controlled infusion of propofol and remifentanil anesthesia,using TOF-Watch SX acceleromyography monitoring of muscle relaxation,and onset time,clinical duration and recovery in-dex(for T1 to return from 25% to 75% of the control twitch)were recorded.Results Compared with group C,the onset time was significantly prolonged,clinical duration and recovery index were short-ened in group J (P <0.05 ).Conclusion Long-term glucocorticoid admininstration could reduce the neuromuscular blocking effect of cisatracurium in elderly patients.

OBJECTIVE: To evaluate the effect of integrated traditional Chinese and Western medicine therapy on the progression of acute renal failure in patients with chronic renal insufficiency. METHODS: Thirty-two patients with chronic renal insufficiency developed acute renal failure recently were treated with Chinese herbs and western drugs intravenously and clysterizing of Chinese herbs liquid for 30 minutes, and the treatment course was 14 days. Assessment of liver and renal function, blood routine, electrolytes and endogenous creatinine clearance rate (Ccr) was performed before and 2 weeks after the treatment. RESULTS: The levels of hemoglobin (HB), white blood cell count (WBC) and serum electrolytes showed no significant changes after the treatment. The levels of blood urea nitrogen (BUN) and serum creatinine (SCr) decreased, while the level of Ccr increased significantly (P<0.05) after the treatment. The total effective rate was 65.6%. CONCLUSION: The integrated traditional Chinese and Western medicine therapy can effectively delay the deterioration of renal function in patients with chronic renal insufficiency accompanied by acute renal failure.

Objective To evaluate the effect of domestic wire-reinforced epidural catheter on the occurrence of adverse events during epidural block.Methods Three hundred ASA Ⅰ or Ⅱ patients of both sexes,aged 18-64 yr,weighing 41-78 kg,scheduled for elective operations under combined spinal-epidural anesthesia,were randomly divided into 3 groups (n =100 each):polyvinyl chloride epidural catheter group (group A),imported wire-reinforced epidural catheter group (group B) and domestic wire-reinforced epidural catheter group (group C).Combined spinal-epidural anesthesia was performed routinely.The corresponding epidural catheter was inserted in each group.The catheterization without difficulty,paresthesia during catheterization,the number of patients in whom blood or cerebrospinal fluid was withdrawn from the epidural catheter,intravascular catheter insertion,injection obstruction,easiness during removal of the catheter,bleeding after removal,postoperative paresthesia and epidural hematoma within 1 week after operation were recorded.Results Compared with A group,the incidences of paresthesia during catheterization,the number of patients in whom blood or cerebrospinal fluid was withdrawn from the epidural catheter,injection obstruction and postoperative paresthesia were significantly decreased (P ＜ 0.05),and no significant change was found in the other parameters in B and C groups (P ＞ 0.05).There was no significant difference in all the parameters between B group and C group (P ＞ 0.05).Conclusion Domestic wire-reinforced epidural catheter can decrease the occurrence of catheterization-induced damage to the nerve and blood vessels and the efficacy is comparable with that of imported wire-reinforced epidural catheter.

Objective To explore the role of the polymorphism of HLA-DRB1/DPB1 in patients with multiple scle-rosis (MS) and optica neuromyelitis (NMO). Methods Fifty-three patients with MS, 30 patients with NMO and 93 normal controls were enrolled in the present study. The HLA-DRB1/DPB1 gene polymorphism and allele frequencies were deter-mined by sequencing-based typing. All the subjects were Southern Han Chinese and were born in Southern China. Re-sults The frequencies of DPB1*0501 were higher in NMO patients than in controls, P=0.001, P (corrected)=0.022. The frequencies of DRB1*1602 DPB1*0501 haplotype were higher in NMO patients than in MS patients, P<0.001,P (cor-rected)=0.040. Conclusions There is significant difference in HLA-DRB1/DPB1 gene polymorphism between MS and NMO patients in a Southern Han Chinese population. The HLA-DPB1*0501 allele might be the susceptibility gene poly-morphism of NMO.
