Objective To discuss significance of continuous monitoring of jugular venous oxygen saturation(S_(jv)O_2)in the course of mild hypothermia treatment(MHT)for severe traumatic brain injury (sTBI).Methods Intracranial pressure(ICP),S_(jv)O_2 and brain tissue pressure(P_(bt)O_2)were contin- uously monitored in 36 cases with sTBI for analyzing the correlation between S_(jv)O_2 and P_(bt)O_2.Results (1)There was negative linear correlation between P_(bt)O_2 and ICP(r=-0.978,P＜0.05),negative lin- ear correlation between S_(jv)O_2 and ICP(r=-0.947,P＜0.05)and positive linear correlation between P_(bt)O_2 and S_(jv)O_2(r=0.965,P＜0.05)within 24 hours and at 36 hours and 48 hours after injury.(2) The cases with decreased S_(jv)O_2 value had a worse outcome than those with normal S_(jv)O_2.meanwhile,the cases with abnormal increase of S_(jv)O_2 value had worse prognosis.Prognnsis was improved significantly with increase of S_(jv)O_2 in certain range(P＜0.05).Conclusion Continuous monitoring of S_(jv)O_2 can reflect the condition of hemicerebral oxygen metabolism and guide treatment and predicting outcome.

Objective To study the association between clinical symptoms,psychosomatic factors and autonomic nervous function in patients with gastroesophageal reflux disease (GERD).Methods Thirty-four patients with GERD diagnosed by reflux disease questionnaire (RDQ) and endoscopy and 15 healthy control subjects were enrolled in this study.All the subjects were divided into two groups,one with normal scores of Zung's self-rating anxiety scale (SAS) and Zung's depression scale (SDS) as GERD (-) and the other with abnormal scores of SAS and SDS as GERD (+).Reflux symptom score was recorded for both groups at the same time.Autonomic nervous function was assessed by their heart rate variability (HRV) on dynamic electrocardiogram (DCG).The time domain parameters analyzed included standard deviation (SD) of average R-R interval during 24 hours (SDNN),SD of average 5-minute sinus heart rate (SDANN),mean square root of the difference of adjoining two R-R interval (rMSSD),and proportion of the heart beats with difference of R-R interval more than 50 ms from the total heart beats (PNN 50),and the frequency domain parameters analyzed included low-frequency (LF),high-frequency (HF) and ratio of LF to HF.Results Average scores of SAS and SDS were significantly higher in patients with GERD than those in healthy controls (48?9 vs 38?6 and 48?11 vs 41?6,respectively,P

OBJECTIVETo study clinical effects of the over-articular external fixator combined with limited internal fixation for the treatment of Pilon fractures caused by high energy.

METHODSFrom September 2003 to April 2011, 36 patients with Pilon fractures caused by high energy were treated with the over-articular external fixator combined with limited internal fixator. There were 25 males and 11 females, ranging in age from 16 to 72 years old,with an average of 38 years old. The diagnoses of all patients were determined by conventional X-ray examination or three-dimensional spiral CT examination. The AOFAS scoring criteria was used to evaluate the therapeutic effects. The patients with comminuted fractures were treated with screw or Kirschner wire fixation without uncovering periost so as to enhance stability between fracture end and bone blocks,followed by the fixation with over-articular external fixators.

RESULTSAll the patients were followed up, and the duration ranged from 4 to 27 months, with an average of 13 months. Thirty-two patients got wound healing at the first stage. And the bone union duration ranged from 2 to 6 months, with a mean of 3 months. According to the AOFAS ankle-hindfoot subjective scoring standard, 13 patients got an excellent result, 20 good and 3 fair, with an score of 88.2 +/- 3.6. Twelve patients had infections at pinhole, 5 patients had pinhole pain. One patient had the fixator broken induced by over loading, who was cured after treatment. There were no complications such as nerve or vascular injuries, or osteomyelitis.

CONCLUSIONThe over-articular external fixation combined with limited internal fixation for the treatment of Pilon fractures caused by high energy is an ideal method, which has such advantages as reliable fixation, simple operation, coincidence with principles of biomechanical fixation, and benefit for fracture healing.

Objective:To purify HLA-DR molecules. Methods: Anti-HLA-DR antibody L243 was purified and coupled with CNBr activated Sepharose 4B gel. Immunoaffinity column was used to purify HLA-DR molecules. Results:Twenty micrograms of HLA-DR molecules were isolated from about 5 g Epstein-Barr virus-transformed human B lymphoblastoid cell line RAJI lysates by affinity chromatography. The purified HLA-DR molecules existed in α/β heterodimers form and could bind to conformation-dependent antibody L243. These HLA-DR molecules were separated into two strands,α and β,by boiling denaturation. These results are the basis for studying MHC Ⅱ binding peptide motif and CD4＋ T cell epitopes of antigens in future.

Objective To explore the necessity of opening nephrostomy tube for patients with septic shock follow-ing the indwelling double-J stent of post-percutaneous nephrolithotomy (PCNL),and provide reference for the treatment of septic shock after PCNL.Methods 60 patients with septic shock after PCNL in a hospital from January 1,2015 to December 30,2016 were chosen,patients were randomly divided into clipping nephrostomy tube group (clipping group,n =30) and opening nephrostomy tube group (opening group,n =30),clinical data of two groups of patients were collected and analyzed.Results After 24-hour treatment,heart rate (HR),mean arterial pressure (MAP),oxygen saturation (SpO2),serum lactate (Lac),and hourly urine volume all improved in both groups of patient compared with pre-treatment(all P＜0.05);HR,MAP,SpO2,Lac,and hourly urine volume in opening group after 24-hour treatment were all significantly different from clipping group (all P＜0.05).Levels of serum procalcitonin (PCT) and C-reactive protein (CRP) in two groups after 3-day treatment decreased significantly compared with pre-treatment (both P＜0.05);PCT and CRP levels in opening group after 3-day treatment were both significantly lower than clipping group (both P＜0.05);cure rate of two groups were both 100.00％,hospitalization time and extubation time in opening group were both shorter than clipping group,and cost was less than clipping group,difference were all significant(all P＜0.05).Conclusion Opening nephrostomy tube on the basis of indwelling double-J stent is necessary for patients with septic shock after PCNL.

Objective To investigate the epidemiological characteristics of human brucellosis in Ulanqab of Inner Mongolia.Methods Three hundred and twenty patients with suspected brucellosis were selected,who had registered in the Ulanqab Center for Endemic Disease Control of Inner Mongolia from April to June 2011.The investigation covered general situation,such as gender,age,occupation and main clinical symptoms and so on.Blood samples were collected,and Rose Bengal plate agglutination test(RBPT) was used for serum screening.Those who were tested positive in RBPT were confirmed with tube agglutination test (SAT).Brucellosis was diagnosed according to Diagnostic criteria for Brucellosis (WS 269-2007).Data were analyzed with statistical software(SPSS 17.0).Results One hundred and thirty-four cases were positive in RBPT of the 320 people surveyed,of which 93 cases were positive in SAT; antibody titers were higher than 1 ∶ 100(++),therefore they were diagnosed as brucellosis,and the ratio was 29.1％(93/320).The number of patients with suspected brucellosis who were negative in SAT test was 41,and the ratio was 12.8％ (41/320).Among the 93 people who were infected,the constituent ratio of farmers and herdsmen who engaged in livestock was the highest,accounted for 63.4％(59/93) and 24.7％ (23/93) of the total number of patients ; infection rate of male (30.9％,55/178) was higher than that of females (26.7％,38/142) ; the number(39) of brucellosis patients who were over the age of 51 was the highest,and the ratio is 42.0％.The onset season mainly in May and August; main route of exposure was bare hands lambing,midwifery and contact with infected sheep pollutants.Conclusions Sheep is the main source of human Brucella infection in Ulanqab.It is the key to control the spreading of brucellosis through improving awareness of disease prevention among farmers and herdsmen as well intensifying the prevention and control of Brucella infection between livestock.
