Objective To observe critical patients with thrombocytopenia,and exam their coagulation function,so as to diagnose disseminated intravascular coagulation(DIC)in the early stage.Methods Totally 56 critical patients complicated with thrombocytopenia were enrolled in the investigation;complete set of DIC tests were performed.A total of 26 cases were diagnosed as DIC according to the criteria from the International Society of Thrombosis Haemostasis(ISTH).The sensitivity,specificity,accuracy,likelihood ratio,predictive value of prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT),fibrinogen(Fg),antithrombin Ⅲ and bleeding signs(including petechia and ecchymosia)were calculated by applying fourfold table.Results The specificity of PT prolongation and Fg reduction was 87.0%;the sensitivity of ATⅢ decrease,and each of PT prolongation,Fg reduction,and bleeding(including petechia and ecchymosis)were as high as 96.0%.Conclusion Multi-markers based on thrombocytopenia are likely to improve sensitivity and specificity of DIC diagnosis.

OBJECTIVE To observe the therapeutic effectiveness and safety of the indigenous teicoplanin in intensive care unit(ICU) patients with severe infections of Gram-positive(G+) cocci.METHODS Sixty patients with severe Gram-positive bacteria infection received teicoplanin which was produced by Xinchang Pharmaceutical Factory of Zhejiang Medicine Co,Ltd.by infusion for 7-14 d.Dosage was adjusted according to the creatinine clearance rate.Maximum temperature,APACHEⅡ score,indicators of inflammatory response,liver and kidney function,microbiologic examination and adverse reactions were observed before treatment and the end of 7-14 day treatment.RESULTS Seventy-two strains of Gram-positive cocci were isolated from 60 patients,in which meticillin-resistant Staphylococcus aureus(MRSA),meticillin-resistant S.epidermidis(MRSE),Enterococcus faecium,E.faecalis,S.haemolyticus and E.gallinarum accounted for 58.33%,8.33%,16.67%,5.56%,8.33% and 2.78%,respectively.After treatment,59 strains of Gram-positive cocci were eliminated while 13 strains were not eliminated and bacteriological eliminated rate(calculated by strains) was 86.1%;In this group,twenty-eight patients were cured while twenty-two cases were markedly improved.The total bacteriological eliminated rate was 81.94%.The incidence of adverse reactions was low and only a slight increase or decrease in platelet count was observed which didn′t require special treatment interventions.CONCLUSIONS Indigenous teicoplanin has certain therapeutic effectiveness and is safe for severe Gram-positive bacteria infected patients,particularly for septic patients with organ damage in ICU.In patients highly suspected with meticillin-resistant staphylococci or enterococci infection,teicoplanin may be a choice for initial empirical treatment.

Objective To study the 2244G→A, 2299 A→G single nucleotide polymorphism (SNP) in the 5' regulatory regions of Toll-like receptor 4 (TLR4) in patients with Gram negative bacteria infection in Shenzhen locality, and to discuss the occurrence, course and prognosis of patients with sepsis. Method Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to detect the genotype of TLR4. After the whole blood DNA of patient was extracted and PCR was amplified, the products were 500bp and 599 bp, and were cut by endonuclease Mae Ⅱ and Sph Ⅰ respectively to determine the SNP 2244G→A and 2299 A→G in TLR4. These two kinds of allele frequencies were statistically calculated in all patients. In the meantime, the incidence of septic shock, average hospitalized days, cost and prognosis of all patients were recorded. Statistical analysis was performed with SPSS version 16 software. ANOVA was used for comparison among multiple groups, and t -test and Sighed rank test were used for paired comparison. Results The 2299 and 2244 sites in the 5' regulatory regions of TLR4 gene of patients with Gram negative bacteria infection in Shenzhen locality had various degrees of changes in single nucleotide. Compared with the documented data from Chinese people in general, there was a significant difference in 2299A→G genotype frequency in residents of Shenzhen locality ( P < 0.05). But there were no statistically significant difference in mortality, incidence of septic shock, average days of ICU stay or ICU cost between TLR4 SNP positive and negative groups of patients. Conclusions There is a wide range of genetic variation in the 2299 and 2244 sites in the 5' regulatory regions of TLR4 among citizens of Shenzhen locality with unique distribution. The 2299A→G genotype frequency probably has differences in distribution and population. The pathogenesis and the prognostic factors of sepsis are complicated, whereas the gene polymorphism may be just one of the factors affecting the prognosis of patients with Gram negative bacteria infection.

ObjectiveTo discuss the clinical efficacy of low dose heparins and low molecular weight heparins (LMWHs) in the treatment of severe traumatic disseminated intravascular coagulation (DIC).MethodsA total of 77 trauma patients (APACHE Ⅱ score for 5-10) with secondary DIC in ICU were included and randomly assigned to three groups,ie,Group A (26 patients,subcutaneously injected with LMWHs at doses of 75-150 U · kg-1 · d-1,with the average incipient dose of 4 000 U/d),Group B (25 patients,subcutaneously injected with heparins at doses of 100-250 U · kg-1 · d-1,with the average incipient dose of 5000 U/d and control group (26 patients,supplemented with simple blood coagulation factor).The injection volume was adjusted according to the level of antithrombin Ⅲ ( ATⅢ ) in each group.Within 28 days in ICU,the three groups were compared in aspects of deaths,hospital day,bleeding rate,thrombin time (TT),prothrombin time (PT),activation part thrombin time ( APTT),fibrinogen (Fg),antithrombin Ⅲ ( AT Ⅲ ) and D-dimer.Results ( 1 ) The differences of mortality were both insignificant in the control group comparel with Group A and Group B respectively at day 28 ( P ＜ 0.05 ).(2) The ICU stay of three groups showed significant differences ( P ＜ 0.01 ),with longer stay of Groups A and B than control group ( P ＜ 0.01 ) and longer stay of Group A than Group B ( P ＜ 0.05 ).( 3 ) Except for AT Ⅲ ( P ＜ 0.01 ),other blood coagulation indices showed no significant difference among three groups.(4) The differences of bleeding rate were not significant between Group A and control group (P ＞ 0.05),but significant between Group B and control group (p ＜ 0.05 ).(5) Related factor analysis indicated significant relationship between AT Ⅲ level and bleeding rate (P ＜0.01 ).ConclusionsLow dose heparins and LMWHs are beneficial to controlling traumatic DIC,but the heparin therapy adjusted by the level of AT Ⅲ with marked correlation bleeding rate shows lower bleeding rate as compared with LMWHs.

BACKGROUND: Although the sternohyoid muscular valves are traditionally used as reparative material for functional reconstruction after partial laryngectomy, the late-term results are not so satisfactory.OBJECTIVE: To investigate the efficacy of using external layer mucoperiosteum valve of thyroid cartilage to repair the wound surface and reconstruct vocal function.DESIGN: A self-controlled observational trial using the patients as subjects.SETTING: Department of otolaryngology of a municipal hospital.PARTICIPANTS: A total of 57 patients with laryngocarcinoma were selected from the Department of Otolaryngology, Shantou Second People' s Hospital, from June 1998 to May 2004. Among them, there were 56 men and 1 woman who were aged 37 to 78 years with the average age of 60. 38 years and whose disease duration was two months to one year with the average of five months.METHODS: In the 57 patients with laryngocarcinoma, their external layer mucoperiosteum valves of thyroid cartilages in the affected side were preserved and inverted into laryngeal cavities, which were used to cover the wound surface and rebuild the vocal fold.MAIN OUTCOME MEASURES: The final outcome indices: changes in the symtoms and function and Karnofsky scores before and after treatment. Risk indices: adverse events and side effects.RESULTS: The operations on the 57 patients were successful. The incidence of respiratory tract obstruction and hoarseness in the patients before operation was 38.9% and 98. 1%, but 1.9% and 96. 3% after treatment. Karnofsky score was 40 and 70 before and after treatment, respectively. No complications of pharyngeal stricture occurred in the near and long term.CONCLUSION: Vertical partial laryngectomy and laryngeal reconstruction with mucoperiosteum valve are easy to operate. The recovery of the wound surface is good, phonation efficacy is satisfacory, and respiratory function is not affected. The treatment has low incidence of complications and satisfactory long-term results.

Objective The aim of this article is to research the radical mastoidectomy and primary tympanoplasty to attain radical cure of the mastoid focus as well as rebuilding the sound- conducting structure of the tympanic cavity to improve the audition. Method The autobone and temporal fascia were taken as the transplants after the radical mastoidectomy under microscopy, and then to carry out the operation of Portmann｀ s tempanoplasty of 2nd and 3rd types of 2nd class.Result Non of the cholesteatoma was relapsed after follow- up for 1～ 4 years.The efficiency rate of tympanoplasty is of 89.47% .The average audition increased was 19 dB HL. Conclussion Radical operation for cholesteatoma should be associated with tympanoplasty if having condition. We recommend that the opening tympanoplasty should be used, and use autobone as a artificial auditory ossicles.

Objective To investigate the antireflux effect of esophagogastrostomy combined with modified Nissen fundoplication after esophageal middle cancer resection.Methods Eighty-two patients with esophageal middle cancer were divided into 2 groups by random digits table method,41 cases underwent esophagogastrostomy with a stapler only (control group),41 cases underwent esophagogastrostomy with stapler combined with modified Nissen undoplication (observation group).Three months after surgery,the patients of the 2 groups completed the research of EORTC QLQ-C30 questionnaire,and examined with esophageal manometry and gastroscopy.Results There was no statistical difference in incidence of postoperative complication between the 2 groups (P ＞ 0.05),death was not found during peroperative period.The scores of heart burn and regurgitation in observation group [(13.2 ± 6.1) and (16.9 ± 3.9) scores] were significantly lower that those in control group [(25.6 ± 7.2) and (26.6 ± 4.2) scores],there were statistical differences (P ＜ 0.05),but there was no statistical difference in score of dysphagia between the 2 groups (P ＞ 0.05).The resting pressure of anastomotic site in observation group [(3.5 ± 2.3) mmHg,1 mmHg =0.133 kPa] was significantly higher than that in the stomach [(2.7 ± 2.1) mmHg],there was statistical difference (P＜ 0.05).The DeMeester score was (54 ± 32) scores,control group was (141 t 84) scores,there was statistical difference (P ＜ 0.05).The incidence of reflux esophagitis in observation group was 48.8％(20/41),in control group was 75.6％(31/41),there was statistical difference (P ＜ 0.05).Conclusions Esophagogastrostomy combined with modified Nissen fundoplication after esophageal middle cancer resection significantly increases the pressure at the anastomotic site,thus reduces the extent of gastroesophageal reflux,which leads to the reduction of the extent of reflux esophagitis and the improvement of the quality of life.

Objective To investigate the effect of 3S jejunal interposition anastomosis in digestive tract reconstruction after radical resection for early gastroesophageal junction adenocarcinoma. Methods One hundred and eighteen patients of early gastroesophageal junction adenocarcinoma who were planned to receive radical proximal gastrectomy from February 2011 to August 2015 were prospectively enrolled and randomly divided into two groups by table of random number, including observation group (3S jejunal interposition) and control group (esophageal remnant gastric posterior wall anastomosis), with 59 patients in each group. Postoperative complications, operative time, nutritional parameters and postoperative quality of life were compared between two groups. Results The operation time in observation group was (152.3 ± 13.1) min, in control group was (146.0 ± 12.5) min, and there was no significant difference (P>0.05). The rate of complication in observation group was 8.5%(5/59), in control group was 13.6%(8/59), and there was no significant difference (P>0.05). The levels of total protein, albumin, hemoglobin, and Vitamin B126, 12, and 18 months after operation in observation group were significantly higher than those in control group (P<0.05). The rate of reflux esophagitis 6, 12 and 18 months after operation in observation group was significantly lower than that in control group (P<0.05). The gastric emptying time 6, 12 and 18 months after operation in observation group was significantly prolonged, compared with that in control group (P<0.05). The scores of whole quality of life, emotional function, body function, pain, tired, appetite, nausea and vomiting, diarrhea and constipation 6 and 18 months after operation in observation group were significantly better than those in control group (P<0.05). Conclusions The 3S jejunal interposition anastomosis in digestive tract reconstruction after radical resection for early gastroesophageal junction adenocarcinoma is a better method. The effect of antirelux is better and can improve the nutriture and quality of live for long time.
