The effects of clonidine as a premedicant were studied during isoflurane-indueed hypotension(IIH). Twenty-four adult patient, ASA grade Ⅰ-Ⅱ, scheduled for elective cerebral surgery, were randomly allocated into two groups. Atropine 0.5mg and luminal sodium 100mg were given I. M. as premedication in group Ⅰ 30 mins before induction, and clonidine 5?g?kg~(-1)P. O. was combined in group Ⅱ 90 mins prior to induction. The methods of both groups were similar in induction and maintenance of anesthesia. The status of hypotension was induced and kept by inhaltion of isoflurane, with MAP being decreased by 25% or so. The arterial plasma Concentrations of adrenaline and noradrenaline were measured by electrochemistry method, at preoperation, prior to hypotension, 15 and 30 mins following IIH and 30 mins after MAP recovery, respectively. The results revealed that as compared with the values in group Ⅰ, the inspired and end-tidal concentrations of isoflurane reduced significantly during induction and maintenance of controlled hypotension (P0.05). It is suggested that clonidine premedication can increase the efficiency of isoflurane for controlled hypotension and do not affect the plasma catecholamine concentration and airway function.

Objective To observe the therapeutic effect of Laparescopic Cholecystectomy(LC) on acute calculous cholecystitis.Methods The data from 35 patients receiving laparoscopic cholecystectomy for acute calculous cholecystitis were analyzed.Results Successful rate of operation was 100% in all cases with no complications such as biliarducy injury,intestines damage and hemorrhage taken place,and mortality was 0%.Conclusion LC is safe for treatment of acute calculous cholecystitis.

Objective To explore the possibility that rat bone mesenchymal cells (BMSCs) can differentiate into hepatocytes under the affection of fetal liver filtrate. Methods PAS and green indigo dye were used to detect glycogen and differential level of hepatocytes, respectively. The concentration of ALT, AST, ALP in the culture supernatant were served as markers of hepaocyte function. Results Fourteen days after induced by the fetal liver filtrate, BMSCs changed their shapes into polygon, oval or round. Some of BMSCs were positive for AFP and ALB at 7 days after induction, then the number of positive cells increased, and most of BMSCs expressed AFP and ALB till 21days. The PAS reaction and indocyanine green(ICG) intaking also appeared at 7days. Enzyme in supernatant such as ALT, AST, ALP were fristly detected at 7days and peaked at 14days,then the level declined. Conclusion The fetal rat liver filtrate was able to induce BMSCs into cells with function and characteristics of hepatocytes.

Clinical isolated syndrome (CIS) is the first episode of neurological symptoms caused by inflammatory demyelinating disease of central nervous system.About 85％ patients with multiple sclerosis (MS) have CIS as onset;about 45％ CIS patients convert to clinically definite MS (CDMS)within two years.Early disease modifying treatment is beneficial to those CIS patients who have high risk of converting to MS,so it is necessary to find predictors to predict CIS converting to MS.In recent years,there are many studies on predictors of CIS converting to MS in CSF,serology,clinical symptoms,and images.We review some recent advances in those studies.

Objective: : To explore the clinical efficacy and safety of microvascular decompression (MVD) combined with internal neurolysis (IN) in the treatment of recurrent trigeminal neuralgia (TN) after MVD. Methods: : Sixty-four patients with recurrent TN admitted to the hospital from January 2014 to December 2017 were divided into two groups according to the surgical method. Twenty-nine patients, admitted from January 2014 to December 2015, were treated with MVD alone, whereas 35 admitted from January 2016 to December 2017 were treated with MVD+IN. The postoperative efficacy, complications, and pain recurrence rate of the two groups were analyzed. Results: : The efficacy of the MVD+IN and MVD groups were 88.6% and 86.2%, and the cure rates were 77.1% and 65.5% respectively. There was no statistically significant difference between the two groups (p>0.05). The cure rate (83.3%) of patients in the MVD+IN group, who were only found thickened arachnoid adhesions during the operation that could not be fully released, was significantly higher than that of the MVD group (30.0%) (p<0.05), while the efficacy (91.7% vs. 70%) of the two groups was not statistically different (p>0.05). For patients whose arachnoid adhesions were completely released, there had no significant difference (p>0.05) in the efficacy (87% vs. 94.7%) and recurrence rate (5.0% vs. 11.1%). The incidence of postoperative facial numbness (88.6%) in the MVD+IN group was higher than that in the MVD group (10.3%) (p<0.01). The long-term incidence of facial numbness was not statistically significant (p>0.05). In the 18–36 months follow-up, the recurrence rate of patients in the MVD+IN group (9.7%) and in the MVD group (16%) were not statistically different (p>0.05). Conclusion : A retrospective comparison of patients with recurrent TN showed that both MVD and MVD combined with IN can effectively treat recurrent TN. Compared with MVD alone, MVD combined with IN can effectively improve the pain cure rate of patients with recurrent TN who have only severe arachnoid adhesions. The combination does not increase the incidence of long-term facial numbness and other complications.

Objective To explore the value of trauma-care check list (TCC) and quick sequential organ failure assessment (qSOFA) on the early diagnosis of severe trauma with sepsis,and analyze the treatment time lines.Methods Totally 120 patients with severe trauma treated in Taizhou People's Hospital from February 2017 to January 2018 were reviewed.Sixty cases adopted TCC and qSOFA trauma care integration process (integration group),and the rest 60 cases adopted systemic inflammatory response syndrome (SIRS) score and emergency surgery multi-section support process (traditional group).According to the 2016 International Sepsis Guide Criteria,the diagnostic sensitivity and specific degrees of the two groups were calculated.The treatment time node,blood loss,complication rate,postoperative survival rate,and the total length of hospital stay of the two groups were analyzed.Results Of the 60 cases in the integration group,32 cases were confirmed severe trauma with sepsis,and 27 cases were confirmed in 41 primary diagnosed patients,with a diagnostic sensitivity of 84.38％ and a specific degree of 50.00％.In the traditional group,30 cases were confirmed severe trauma with sepsis,and 25 cases were confirmed in 38 primary diagnosed patients with a diagnostic sensitivity of 83.33％ and a specific degree of 56.67％.The significant shorter MDT consultation time,primary diagnosis time of sepsis,the duration from injury to surgery time and total hospitalization time were statistically significant different between the two groups (P＜0.05).Patients in the integration group had significantly lower incidence of postoperative complications and 28-day fatality rate,but there was no significant difference between them (P＞0.05).Conclusions TCC and qSOFA score in the treatment of severe trauma can optimize salvage process,significantly shorten the treatment time,and reduce postoperative complications.Moreover,qSOFA score and SIRS score have the same effect on the early diagnosis of sepsis in patients with severe trauma.

The aim of this study is to assess the antibacterial and anti-biofilm properties of the lipid extract from Mantidis ootheca against the gentamycin resistant Pseudomonas aeruginosa. The chemical composition of the lipid extract and its relative proportion were determined using the technique of gas chromatography coupled with mass spectrometry (GC-MS). Antibacterial susceptibility tests were performed using a disc diffusion assay and the minimum inhibition concentration (MIC) was determined by way of the agar dilution method. The anti-biofilm test was carried out with crystal violet staining and scanning electron microscopy (SEM). There were 16 compounds detected, and the most abundant components were sesquiterpenoids, monoterpenes, and trace aromatic compounds. The MIC for P. aeruginosa was 4 mg/ml and the eradication effect on preformed biofilms was established and compared with a ciprofloxacin control. The results of our study indicated that a lipid extract from M. ootheca could be used as a topical and antibacterial agent with anti-biofilm activity in the future.
