Objective To investigate the clinical significa nc e and the relationship between the serum squamous cell carcinoma antigen (SCC-A g) levels and the biological characteristics in patients with cervical carcinoma . Methods The pre-post-treatment sera from 500 patients w ith cervical carcinoma from 1998 to 2002 were analyzed for the SCC-Ag levels by IMX; and the correlation between the SCC-Ag level and the clinicopathologic ch aracteristics were also detected. Results Significant corre lation was found between the pre-treatment SCC-Ag level and pathologic classif ication, and clinical stage (P0.05); The pre-treatm ent SCC-Ag level is significantly higher than that of post-treatment (P

Objective To study the relation between the surgical extent and number of lymph node dissection and the effect of metastatic lymph node number on the prognosis of proximal gastric cancer. Method Thirty-one patients with proximal gastric cancer underwent D_2 or D_3 operation, and lymph node were harvested from specimen. The number of lymph node dissection in proximal gastrectomy was compared with that in total gastrectomy. Results A total of 1971 lymph nodes were obtained from the 31 specimens, the mean was 63 per case. There were 57 lymph nodes per case for patients with proximal gastrectomy and 71 per case with total gastrectomy,64 per case with left half pancreaticosplenectomy and 63 per case with splenectomy. According to the new 5th N stage system, the 5 year survival of N_1,N_2,N_3 were 36%, 11%, and 0 respectively. Conclusion Along with the wide invasion of the carcinoma wide resection with extended lymph node dissection is mandatory, reserved left half of the pancreas has no influence on the number of harvested lymphnode, the new quantitative N staging is superior to the old in predicting the prognosis.

ObjectiveTo analyze the cause of and the prevention for the postoperative complications in adult patients undergoing Lichtenstein herniorrhaphy for inguinal hernia. Methods Retrospective review was made on 334 inguinal hernia cases receiving Lichtenstein repair in our hospital. Results Recurrence was found in 1 case(0 3%). Significant postoperative pain occurred in 5 patients. Four cases (1 2%) suffered from superficial wound infection, and 5 cases(1 5%) were complicated with subcutaneous seroma. Conclusions Lichtenstein′s tension free repair for the treatment of adult inguinal hernia has the advantage of less postoperative pain and low recurrence.

Objective To investigate the long-term anticoagulation starus and relation of INR and complica-tion,best anticoagulation range and clinical significance in patients after mechanical heart valve replacement. Meth-ods The data of blood clotting test series(containing PT,PT% ,PTR,INR,Fbg,APTT) for patients after 6 months of mechanical heart valve replacement were collected, then the cases were divided into 4 groups according to their INR levels( group Ⅰ : INR < 1.5; group Ⅱ : INR 1.5 ～ 2.0 ; group Ⅲ : INR 2.1 ～ 2.5 ; group Ⅳ : INR > 2.5 ). Results Group Ⅰ contained 28 person-times, with their dosage of warfarin for (3.61 ± 1.44 ) mg, INR 1.38 ± 0. 12, core-bral embolism occurred for 4 person-times,with a inception rate of 14%. Group Ⅱ contained 92 person-times,with their dosage of warfarin for (3.5±1.37)mg,INR 1.65±0. 14,hemorrhinia occurred for 2 person-times,with a in-ception rate of 2%. Group Ⅲ contained 80 person-times, with their dosage of warfarin for (3.18±1.63 )mg, INR 2.23±0.19 ,bematuria occurred for 2 person-times, bemorrhinia occurred for 2 person-times, with a total inception rate of 5% ; Group Ⅳ contained 16 person-times, with their dosage of warfarin for ( 2.32 ± 1. 23 ) mg, INR 2.80± 0.19, hemorrhinia occurred for 2 person-times and hemoptysis occurred for 1 person-times, with a total inception rate of 18.7%. The person-times in group Ⅱ and Ⅲ accounted for 79.6% and the complication rate was the lowest when INR was between 1.5-2.5. Conclusions INR levels between 1.5-2.5 is the most secure, which is the best antico-agu]ation range in our region. Since the anticoagulation strength dynamically changes, the long-term anticoagulation status in patients after mechanical heart valve replacement should be deeply concerned.

Objective To investigate the effect of supratemporalis approach scalp coronal incision for treating craniomaxillofacial fracture.Methods Fifty-two cases of traditional coronal scalp approach were retrospectively analyzed for understanding the facial nerve damage situation.Then 30 cases a.dopted the supratemporalis approach scalp coronal incision and the facial nerve damage situation was recorded.The follow-up observation lasted for 6-24 months.Results The facial contour,mouth opening and occlusion function recovered well after the operation in all 82 cases.Eight cases of temporary facial nerve injury were observed in the traditional approach group.No case of facial nerve injury occurred in the supratemporalis approach group(P＜0.05).Conclusion The supratemporalis approach scalp coronal incision can effectively avoid the facial nerve injuries.

Objective To observe the effects of electroacupuncture on the motor function and expressions of Irisin,Decorin and Myostatin in skeletal muscle of SAMP8 mice;To explore the mechanism of electroacupuncture in the treatment of the motor dysfunction of Alzheimer disease(AD).Methods Totally 247-month-old male SAMP8 mice were randomly divided into model group and electroacupuncture group,with 12 mice in each group,and the 12 male SAMR1 mice with the same age were set as the control group."Baihui","Dazhui"and"Shenshu"were selected in the electroacupuncture group,once a day,8 days as one course of treatment,with an interval of 2 days,for a total of 3 courses.The control group and the model group were not intervened.The motor function of mice was tested by grip strength test,pole climbing test and open field test,the mRNA expressions of Irisin,Decorin and Myostatin in quadriceps muscle were detected by RT-qPCR,and the protein expressions of Irisin,Decorin and Myostatin in quadriceps muscle were detected by immunohistochemistry and Western blot.Results Compared with the control group,the grip peak and duration of the mice in the model group decreased,head turning time and pole climbing time were prolonged(P<0.01),the mRNA and protein expressions of Irisin and Decorin decreased(P<0.05,P<0.01),and the expressions of Myostatin mRNA and protein increased(P<0.05).Compared with the model group,the grip peak and duration of the mice in the electroacupuncture group increased,head turning time and pole climbing time were decreased(P<0.05),the mRNA and protein expressions of Irisin and Decorin increased(P<0.05),and the expressions of Myostatin mRNA and protein decreased(P<0.05).Conclusion Electroacupuncture can improve the motor dysfunction of SAMP8 mice,and its mechanism may be related to regulating the expressions of Irisin,Decorin and Myostatin in skeletal muscle.

Background:From April to July in 2009 and 2010,unexplained severe hemorrhagic fever-like illnesses occurred in farmers from the Huaiyangshan mountains range.Methods:Clinical specimens (blood,urine,feces,and throat swabs) from suspected patients were obtained and stored.Mosquitoes and ticks in affected regions were collected.Virus was isolated from 2 patients and characterized by whole genome sequencing.Virus detection in additional patients and arthropods was done by virus-specific reverse transcription (RT) PCR.Clinical and epidemiological data of RT-PCR confirmed patients were analyzed.Results:An unknown virus was isolated from blood of two patients and from Haemaphysalis ticks collected from dogs.Whole genome sequence analysis identified the virus as a novel member of the family Bunyaviridae,most closely related to the viruses of the genus Phlebovirus within which it forms a separate lineage.Subsequently,infection was confirmed by RT-PCR in 33 of 58 suspected patients.The illness in these patients was characterized by fever,severe malaise,nausea,vomiting,and diarrhea.Prominent laboratory findings included low white cell- and platelet counts,coagulation disturbances,and elevation of liver enzymes.Hemorrhagic complications were observed in 3 cases,5 (15%) patients died.Conclusions:A novel tick-borne Bunyavirus causing life-threatening hemorrhagic fever in humans has emerged in the Huaiyangshan mountain areas of China.Further studies are needed to determine the epidemiology,geographic distribution and vertebrate animal ecology of this virus.
