Objective To summarize the clinical experience of Gilbert tension-free hernioplasty in the elderly patient under local anesthesia. Methods Seventy-six elderly hernia patients operated by Gilbert tension-free hernioplasty under local anesthesia were analyzed in operating time, postoperative complications, hospitalization days and recurrence rate, etc. Results Patients with abdominal hernia were all cured. The average operation time was 25.7 minutes and the time staying in bed after operation was 2-5 hours. The complications of incision pain, foreign body sensation and scrotum hydroceles after operation were observed in 8, 4 and 3 patients respectively. The average hospitalization period was 2.3 days. All patients were followed-up for 1-12 months and no recurrence and infection were observed. Conclusions Gilbert tension-free hernioplasty under local anesthesia is an ideal operation to treat abdominal hernia for elderly patients with less interference to physiological function, quick recovery and less complications.

Objective To ohaerve the behavior of PD rat models treated with different dosages of levodopa and analyze the relation- ship between levodopa - induced dyskinesia (LID) and dosage of levedopa. Method The successful PD rat models were set up by 6-OHDA injection into right MFB. Two groups were divided according to the different treatment dosages of levodopa, which were given through perito- neal injection twice a day for 21days. One group was given for 10 mg/kg body weight, the other for 50 mg/ kg body weight. The score of AIM and rotational behavior were observed. Results Among altogether 28 female SD rats, 22 were chosen as the successful PD models and the successful rate arrived at 78. 57%. LID could be induced in both groups, but there were great differences in occurrence and duration time of AIM, AIM score, pharmacodynamic action time, and rotational behavior between these two groups( P<0.05). Conclusions The be- havior of LID has great relationship with the given dosage of levodopa.

Objective To explore the value of neopterin (Np) in early diagnosis and risk stratification of sepsis.Methods A total of 82 patients admitted to the emergency department from April 2013 to February 2014 were enrolled in the study.They were divided into two groups:sepsis-free group (n =8) and sepsis group (n =74).Patients' APACHE Ⅱ scores were calculated within 24 hours after admission,and then their plasma levels of Np and procalcitonin (PCT) were detected and analysis was carried out to find the correlation between plasma levels of Np,PCT and acute physiology and chronic health evaluation Ⅱ score (APACHE Ⅱ score) in two groups.And 74 patients in sepsis group were further divided into three subgroups according to their APACHE Ⅱ score:Ⅰ subgroup (score ＜ 15,n =27),Ⅱ subgroup (score 15 to 24,n =32),and Ⅲ subgroup (score ＞ 25 or more,n =15).The differences in plasma Np and PCT levels were compared among three subgroups and correlation analysis of Np levels with PCT levels and APACHE Ⅱ scores was carried out.Results The plasma levels of Np,PCT and APACHE Ⅱ scores in sepsis group were higher than those in sepsis-free group (P ＜ 0.05).In sepsis group,the plasma levels of Np and PCT were gradually increased with the increasing severity of sepsis (P ＜ 0.05);In sepsis group,the plasma levels of Np,PCT and APACHE Ⅱ scores were positively correlated (P ＜0.01).The area under receiver operating characteristic curve (ROC) of Np was O.79 and the area under ROC of PCT was 0.75,both of which had high diagnostic accuracy.Conclusions Neopterin has greatly useful value in early diagnosis and risk stratification of sepsis.

Objective:? N oxalo L ?,? diaminopropionic acid were isolated from the powder of red ginseng. its physiological characteristics were studied. Method:This material is obtained by CM Sephadex C 25 and FPLC MonoQ. We have examined the effect of ? N oxalo L ?,? diaminopropionic acid on contraction of artery of guinea pig. Result:When histamin and adrenalin do not exist, there is neither contraction nor relaxation. It can strengthen induction of contraction of artery of guinea pig, but it has no such effect on adrenalin. Besides, it doesn't induce plaque coagulation through adrenalin, ADP blood coagulation enzyme and collagen. It doesn't suppress the transformation from tension peptide of blood vessel to enzyme.Conclusion:Hemostatic effect of ? N oxalo L ?,? dlaminopropinomie acid may caused by vesseles contraction through promoting Histamine.

Neural crest stem cells originated from hair follicle (epidermal neural crest stem cell, EPI-NCSC) are easy to obtain and have potentials to differentiate into various tissues, which make them eminent seed cells for tissue engineering. EPI-NCSC is now used to repair nerve injury, especially, the spinal cord injury. To investigate their effects on repairing peripheral nerve injury, EPI-NCSC from a GFP-SD rat were primarily cultured on coated dishes and on a poly lactic acid coglycolic acid copolymer (PLGA) membrane. Methyl thiazolyl tetrazolium (MTT) assay showed that the initial adhesion rate of EPI-NCSC was 89.7% on PLGA membrane, and the relative growth rates were 89.3%, 87.6%, 85.6%, and 96.6% on the 1st, 3rd, 5th, 7th day respectively. Cell cycles and DNA ploidy analysis demonstrated that cell cycles and proliferation indexes of cultured EPI-NCSC had the same variation pattern on coated dishes and PLGA membrane. Then cultured EPI-NCSC were mixed with equal amount of extracellular matrix and injected into a PLGA conduit to connect a 10 mm surgery excision gap of rat sciatic nerve, Dulbecco's Modified Eagle's medium (DMEM) was used to substitute EPI-NCSC in the control group. After four weeks of transplantation, the defected sciatic nerve achieved a histological restoration, the sensory function of rat hind limb was partly recovered and the sciatic nerve index was also improved. The above results showed that a PLGA conduit filled with EPI-NCSC has a good repair effect on the peripheral nerve injury.

Objective To investigate clinicopathological features of endometriosis-associated epithelial ovarian carcinoma.Methods Retrospective follow-up study,clinicopathological data from patients with ovarian epithelial carcinoma were retrieved,analyzed and compared.Among the 727 cases,34 were found to originate from endometriosis (group A),33 were found to have co-existing ovarian endometriosis (group B),and the remaining 660 had no ovarian endometriosis at all (group C).Result Seven hundred and twenty-seven epithelial ovarian carcinoma patients were identified and their ehnicopathological data retrieved.Sixty-seven (9.2%) of these cases were found to have coexisting endometriosis.The frequency of malignant tumors arising from ovarian endometriosis in this case series was estimated to be 0.87% (34/3890).The mean (standard deviation) age in groups A,B,and C were(47.2±1.3),(47.8±1.2),(51.2±0.4) years,respectively,with patients in group C being significantly older (P = 0.013).Patients with coexisting ovarian endometriosis were mostly diagnosed at stage Ⅰ (P = 0.000)and having subtype of clear-cell (P =0.000),while other patients were mostly diagnosed at stage Ⅲ (P =0.001),and having subtype of serous carcinoma (P =0.000).The estrogen receptor (ER) positivity was significantly lower in groups A and B than that in group C (22.2%,31.6% vs 43.9%;P =0.018),but the difference in positivity of progestogen receptor among the three groups did not reach statistical significance (22.2%,15.8% vs 35.5%;P =0.082).While the five-year overall survival rate for all patients was 55.6%,significant difference in overall survival among the three groups was found 78.9%,92.8%,51.9%,respectively,for groups A,B and C (P =0.000).Conclusion Patients of endometriosis-associated epithelial ovarian carcinoma,especially patients with tumors arising from endometriosis,were found to be younger,having a significant lower stage and a better survival,and were mostly diagnosed with the subtype of clear-cell.

ObjectiveTo explore the early diagnostic value of pro-adrenomedullin (pro-ADM) in sepsis. Methods A prospective study was conducted. Eighty-two patients with acute infection admitted to Department of Emergency of Shanxi Medical University Second Hospital from April 2013 to March 2014 were enrolled. According to the diagnostic criteria of sepsis, the patients with acute infection were divided into ordinary infection group [infection without systemic inflammatory response syndrome (SIRS),n = 25] and sepsis group (infection combined with SIRS, n = 57). According to degree of severity of sepsis, the latter group was subdivided into three subgroups: sepsis group (n = 22), severe sepsis group (n = 27) and septic shock group (n = 8). Twenty-four healthy persons were included to serve as healthy control group. The venous blood from all the research objects in hospital was collected within 24 hours. The levels of pro-ADM and procalcitonin ( PCT ) were determined by enzyme linked immunosorbent assay (ELISA), and acute physiology and chronic health evaluationⅡ (APACHEⅡ) score was recorded. The relationship between pro-ADM and PCT and also APACHEⅡ score was analyzed with Pearson correlation analysis. The receiver-operating characteristic curve (ROC) of pro-ADM and PCT were used to evaluate the diagnostic acuity of sepsis.Results The plasma levels of pro-ADM, PCT and APACHEⅡ score in sepsis group were significantly higher than those in ordinary infection group and healthy control group [pro-ADM (ng/L): 66.69±1.73 vs. 53.43±2.70, 45.87±1.43; PCT (ng/L):1 336.49±40.26 vs. 1 083.09±47.99, 959.04±37.53; APACHEⅡ score: 14.60±0.81 vs. 8.10±1.14, 3.00±1.15,allP< 0.01]. With the aggravation of sepsis, the levels of pro-ADM, PCT and APACHEⅡ score were gradually increased, and there were significant differences among sepsis, severe sepsis, and septic shock groups [pro-ADM (ng/L): 64.91±2.50, 73.56±2.80, 84.67±4.52; PCT (ng/L): 1 152.65±48.62, 1 233.93±63.06, 1 475.71±109.93;APACHEⅡ score: 12.91±1.15, 14.55±1.14, 19.37±2.40,P< 0.05 orP< 0.01]. Pearson correlation analysis results showed that the level of pro-ADM was positively related with PCT (r = 0.473,P = 0.006), and it was also positively correlated with APACHEⅡ score (r = 0.707,P = 0.008). ROC curve analysis showed that area under the ROC curve (AUC) of pro-ADM for diagnosis of sepsis was 0.823 (P = 0.003). When the cutoff value was 59.40 ng/L, the sensitivity was 80.7%, the specificity was 68.0%, the positive predictive value was 85.2%, and the negative predictive value was 60.7%. AUC of the PCT for diagnosis of sepsis was 0.653 (P = 0.043). When the cutoff value was 1 194.67 ng/L, the sensitivity was 68.4%, the specificity was 64.0%, the positive predictive value was 81.8%, and the negative predictive value was 44.7%. It was proved that the pro-ADM had a higher diagnostic value for sepsis than PCT.Conclusion The plasma levels of pro-ADM can be used as an early indicator in diagnosis and severity evaluation and prognosis in patients with sepsis .
