Objective To understand the status and developmental trends of the research on anterolateral thigh flap. Methods The PubMed search was downloaded and the results were imported into the EndNote database,then the distribution was analysed by age,nation,language,periodical and frequency.Results There were 236 articles on anterolateral thigh flap in PubMed from 1996 to August 2006.The amount of articles multiply increased from 2002 to August 2006,at eighty percent of all.They were published in 8 languages,in 47 journals and from 9 countries.China and the USA are the major countries of the publication,with 77 articles each,which altogether took up 65.2% of the total.Words of a high frequency are as follows: free skip flap,island skin flap,ultrathin skin flap,perforating artery,and descending branch of lateral circumflex femoral artery,the frequency ratio of which is up to 97.46%.Conclusion The papers on anterolateral thigh flap are written mainly by China and USA;English is the main publishing language;The articles are chiefly published by Plast Reconstr Surg and other 8 journals.The research emphases of the anterolateral thigh flap are on free skip flap,perforating flap,ultrathin skin flap,and island flap.Angiography and 3D-reconstruction are the recent techniques for the research.

Objective:To understand the difference of prevalence rate and main symptoms of northwest dryness syndrome(NDS) of the long staying and temporary residents at Xinjiang by comparing the cotton workers in Shihezi come from mainland with inhabitant of Xinjiang,under the environment of NDS.Methods:To design questionnaire according to the Chinese medicine theories and modern epidemiology method,and carry out sampling questionnaire in cotton workers of Shihezi,Hetian,Urumqi,Yili and Leshan,then carry out syndrome differentiation with computation and statistical analysis about NDS.Results:The distributing date,syndromic types and main symptoms scores of NDS in the cotton workers in Shihezi and other areas were obtained from 3658 questionnaires.The highest attack rate of NDS on cotton workers was in Hetian.The attack rate in Sichuan was higher than that in Shizihe(P0.05).The higher scores,symptoms of DNS in Shizihe were the main symptoms of dryness syndrome,but the higher scores,symptoms of NDS in Hetian,Yili and Urumqi were the characteristic symptoms.The external-dryness score of cotton workers in Shihezi was obviously higher than that in other areas(P

The Proposal for the Standardization of Urinary Sediments Examination and the expert consensus have provided effective and timely instruction on urinalysis normalization,but there are still some puzzles about the methods and requirements on quality improvement for urinalysis normalization.This paper is discussing about some issues referring to American and European urinalysis guidelines,which include establishment of examination procedure,specifications and methods of testing system evaluation,specimen stability,the influence of sample centrifugation,the usage of sample staining,confirmation tests,requirements on result reporting,internal quality control and external quality assessment.These discussions will contribute to the quality improvement of urinalysis in clinical laboratories.

Objective To evaluate the risk factors of gallstone occurrence after gastrectomy for gastric cancer.Methods Relevant documents published from 1990 to 2014 were retrieved through Pubmed,Cochrane Library,Embase,Web of Science CNKI,Wan Fang and VIP databases search.The Meta-analysis was applied with RevMan 5.3 software for Odds ratio and 95％ CI.Results 24 studies were selected for this Meta-analysis which included 3 randomized controlled trials,13 cohort studies and 8 case-controlled studies.These 24 studies included patient number which ranged from 32 to 893.The pooled OR (95％ CI) and P values of OR (95 ％ CI) for physiologic digestive tract reconstruction were 0.53 (0.44 ～ 0.65,P ＜ 0.05) ;amount of resection of stomach,1.98 (1.29 ～ 3.04,P ＜ 0.05) ; lymphadenectomy,0.38 (0.21 ～ 0.72,P ＜ 0.05) ; vagotomy,0.24 (0.13 ～ 0.45,P ＜ 0.05) ; and pylorus preservation,0.70 (0.48 ～ 1.02,P ＞ 0.05).Conclusions Physiologic digestive tract reconstruction and vagus nerve preservation reduced occurrence of gallstones after gastrectomy.On the other hand,total gastrectomy and extensive lymph node dissection increased the occurrence.There was no significant difference in the occurrence of gallstones whether there was pylorus preservation or not.

Objective To observe the influence of intensive insulin therapy on inflammatory fac-tors and prognosis in severe multiple trauma patients.Methods A total of 53 cases of severe multiple trauma were randomly divided into the treatment group(n =27)and the control group(n =26).Besides basic treatment,patients in the treatment group received additional intensive insulin therapy by micro-pump.The level of blood glucose in the control group was controlled under 11.1 mmol/L.Levels of TNF-α,IL-1β,IL-6,and CRP were tested before and after treatment.Multiple organ dysfunction syndrome,noso-comial infection rate,and mortality rate were also observed.Results The levels of TNF-α,IL-1β,IL-6, and CRP in the treatment group were significantly lower than those of the control group(P <0.05 or P <0.01).The incidence of multiple organ dysfunction syndrome,nosocomial infection,and mortality rate in the treatment group was lower(P <0.05).Conclusion Intensive insulin therapy can effectively decrease the expressions of inflammatory factors in patients with severe multiple trauma,improve the prognosis,re-duce the incidence of nosocomial infection and mortality.

With the development of the dialysis technology,the survival time of patients with chronic renal failure is prolonged,while more complications which affect the quality of life or even threat the life of patients are followed.Secondary hyperparathyroidism(SHPT)with a certain incidence and mortality is one of the common complications,and its main characteristic performances ale hyperphosphatemia,hypocalcemia and high level of parathyroid hormone.Most patients Can be cured by the treatment of medicine while surgical treatment is still required by some cases in which the disorder of the parathyroid function can not be well regulated through medicine treatment.The purpose of this paper is to make a review of the recent studies of surgical treatment in patients with SHPT.

BACKGROUND: Some researches report that diffusion-weighted imaging (DWI) can appear abnormal signal in minutes after cerebral ischemia.OBJECTIVE: To investigate the manifestation and regularity of diffusion coefficient in middle cerebral artery occlusion (MCAO) of rats after cerebral ischemia.DESIGN: Randomized controlled study.SETTING: Neurological Department of Clinical College of ChongqingMedical University.MATERIALS: The experiment was conducted at the Radiological Department of the First Affiliated Hospital of Chongqing Medical University from April to July 2004. Totally 18 adult Wistar rats with clean grade were randomly divided into three groups: control group, sham operation group and cerebral ischemia group with 6 rats in each group.METHODS: The origin of right middle cerebral artery was blocked with filament into right internal carotid. In the sham-operated group, the filament was just inserted into the common carotid artery not into the origin of middle cerebral artery, rats in normal control group were not treated with anything after anesthesia. MRI experiments were performed on a 1.5 T GE signa Highspeed NMR spectrometer to obtain DWI and ADC values at the time-point of 7, 15, 30, 60 minutes, 3,6, 12, 24 hours, 3, 7, 15 days, 1 and 2 months after operation.MAIN OUTCOME MEASURES: Changes of ADCs in infarct hemisphere and contralateral hemisphere.RESULTS: There was no significant change in MRI T1-and T2-weighted imaging in rats at 7 minutes post-infarction, but abnormal high intensity was emerged during the period of 1 hour to 3 hours, and enlarged over time. Finally, the infarction area located the right basal ganglia and the frontal-parietal lobes at 12 hours and increased less significantly later.Focal abnormal high signal was noted in DWI 7 minutes after cerebral ischemic insult, and the ADC values was decreased at the same time,reduced gradually after significant recover at 30 minutes, dropped to the lowest level at 12 hours and again increased at 24 hours, since then all the ADC values were remained high throughout follow-up, which increased by 5 times at 2 months than that at 12 hours. Correspondingly,rADC values showed the contrary pattern of evolution.CONCLUSION: It is reflected that ADC is highly sensitive not only to onset of cerebral ischemia but also to chronic cerebral ischemia.
