Objective To study the diagnostic values of a distintegrin and metalloproteases-8 (ADAMS) in non-small cell lung cancer(NSCLC).Methods The serum protein level of ADAM8 was assayed by ELISA in 62 NSCLC patients,27 lung benign lesions and 32 healthy people.Results The serum levels of ADAM8 of NSCLC [(456.88±143.87)ng/L] were higher than those with lung benign lesions[ (271.63±74.20) ng/L] and normal controls(253.09±72.15 ng/L) (P<0.01), but there was no significant difference between lung benign lesions and normal controls (P0.05).No significant difference was found between adenocarcinoma and squamous cell carcinoma in serum ADAM8 level,the serum levels of ADAM8 in NSCLC with stages Ⅲ-Ⅳ [ (498.80 ± 151.80) ng/L] were higher than those with stages Ⅰ -Ⅱ[(385.80±95.85) ng/L] (P <0.01 ).The diagnostic sensitivity of detection of ADAM8 for NSCLC was 77.4% and the specificity was 90.6%.Conclusion The overexpression of ADAM8 in serum of NSCLC patients indicates that ADAM8 is related with occurrence and metastasis of NSCLC;De-tection of ADAM8 could assist the diagnosis for NSCLC.

Objective To investigate clinical effect of in vitro maturation(IVM)of immature oocytes transferred from conventional in vitro fertilization embryo transfer(IVF-ET) cycles.Methods From January 2008 to June 2009.medical documents of 155 infertile patients underwent IVF-ET in the Reproductive Medical Center of Fimt Affiliated Hospital of Wenzhou Medical College were analyzed retrospectively.If more than 20 oocytes were monitored after 5-7 days of ovulation induction or follicular developmental retardation were confirmed after 8-13 days of ovulation induction.according to patients' wish,IVM were transferred in 60 cycles(group A).In the mean time.IVF was continued in 95 cycles (group B).The mean dosage of gonadotropin,the cancel lation rate of cycles,the mean numbers of oocytes retrieved and maturation,the rate of fertilization and excellent quality embryos.pregnancy outcome and the incidence rate of ovarian hyperstimulation syndrome(OHSS)were compared and analyzed.Results The rates of embryo transfer were 92%(55/60)in group A and 63%(60/95)in group B,which showed significant differences (P<0.05).In group A,the mean dosage of the gonadotropin,the mean number of oocytes retrieved,the cleavage rate and OHSS rate were(1030±468)U,10±6,82.2%(231/281)and O,and were(1544±338)U,14±4,94.0%(502/534)and 35%(21/60)in group B,respectively,all data abeve exhibited statistieal difference between two groups(P<0.05).However,the rates of fertilization and excellent quality embryos had no significant differences between two groups(P>0.05).In group A,the rate of clinical pregnancy per transfer was 53%(29/55)and multiple pregnancy was 14%(4/29),and were 47%(28/60) and 32%(9/28)in group B,they all had no significant differences (P>0.05).Conclusion IVM of immature oocytes used in conventional IVF cycles not only obtained a high clinical pregnancy rate,but also reduced gonadotropin using dosage and avoided OHSS completely.

Objective To observe the effect of local mild hypothermia and Naloxone in the treatment of acute intracerebral hemorrhage. Methods Forty-five patients with acute intracerebral hemorrhage were randomly divided into 4 groups:a control group(12 patients),a hypothermia group(11 patients),a Naloxone group(11 patients)and a hypothemrmia plus Naloxone group(11 patients).The patients in the control group were managed with conventional interventions including the administration of 6-aminocaproic acid within 24 hours and dehydrant when intracranial pressure was high.Those in the hypothermia and Naloxone groups were treated with local hypothermia at 33～34 ℃ for 3 days or intravenous transfusion of Naloxone at 4 mg/d in addition to the conventional intervention.Those in the combination group were treated with local hypothermia and intravenous Naloxone in addition to the conventional intervention.Immediately after admission and 2 weeks after treatment,head CT scans were conducted to observe the volume of cerebral hematoma and edema.The patients' neurological function was scored according to the European Stroke Standards(ESS)before and after treatment. Results There was no significant difference among the 4 groups in terms of the volume of hematoma and edema or in their ESS scores before treatment.After treatment,any differences among the 4 groups with regard to hematoma volume were not significant.The volume of edema in the hypothermia group was similar to that in the combination group and significantly lower than that in the Naloxone andcontrol groups.Hematoma volume in the Naloxone group was significantly lower than that in the control group.After treatment,the ESS scores were significantly higher in the combination group than that in hypothermia group,and scores in the hypothermia group were significantly higher than in the Naloxone group.ESS scores in the Naloxone group were significantly higher that in the control group. Conclusion Local mild hypothermia and Naloxone treatment can inhibit cerebral edema and enhance recovery of neurological function in patients with intracerebral hemorrhage.Local mild hypothermia has advantages over Naloxone in inhibiting the development of cerebral edema and in promoting recovery of neurological function.Local mild hypothermia in combination with Naloxone further inhibits edema,and it can enhance neurological function to a greater extent.

Objective: The present study evaluated postoperative reactions in adjacent teeth after the extraction of lower-level horizontal-impacted mandibular third molars using a T-shaped splitting method. Methods: A total of 101 patients with lower-level horizontal impaction of mandibular third molars were selected and randomly divided into two groups. The impacted mandibular third molar was extracted using a T-shaped splitting method in group A （56 cases）, and the traditional two-section method was used in group B （45 cases）。 Postoperative reactions, including temperature sensitivity, percussion pain and mobility in the adjacent teeth, were compared between the 2 groups at 1-week, 2-week, and 1-month follow-up visits. The SPSS 13.0 software package was used for the statistical analysis. Results : The postoperative reactions of temperature sensitivity （χ21w= 11.81, χ22w = 17.43, P < 0.05）, percussion pain （χ21w = 8.70, χ22w = 4.75, P < 0.05） and mobility （χ21w = 4.50, χ22w = 7.10, P < 0.05） in adjacent teeth in group A were significantly less than those in group B at the 1-week and 2-week follow-up visits. The temperature sensitivity in adjacent teeth in group A was significantly less than that in group B at the 1-month follow-up visit （χ2 = 7.10, P < 0.05）, but percussion pain and mobility in adjacent teeth disappeared in both groups. Conclusion The T-shaped splitting method for the extraction of mandibular lower-level horizontal impacted third molars can reduce the postoperative reactions in adjacent teeth.

OBJECTIVETo analyze clinical features and genetic mutations in a Chinese family affected with autosomal dominant caveolinopathies.

METHODSClinical data of the proband and her family members were collected. Genomic DNA was extracted from peripheral blood samples with a standard procedure. Next generation sequencing was carried out for the proband, and direct sequencing was employed to detect potential mutation of the CAV gene.

RESULTSThe proband presented with slowly progressing distal muscle weakness and atrophy, especially distal upper limbs and muscular soreness during early childhood, with her CK level moderately elevated and EMG showing myogenic and neurogenic injuries. Her sisters presented mild symptoms with hand muscle atrophy and fasciculation after exercise. A heterozygous missense mutation c.80G>A (p.Arg27Gln), which was reported as being pathogenic, was identified in the CAV3 gene in the proband and her sisters.

CONCLUSIONA heterozygous c.80G>A (p.Arg27Gln) mutation in the CAV3 gene probably underlies the autosomal dominant caveolinopathies in this Chinese family.

The research literature on the mechanism of Achyranthis Bidentatae Radix and its main components in the treatment of osteoporosis was reviewed. It was found that Achyranthis Bidentatae Radix could promote the osteogenic differentiation of bone marrow mesenchymal stem cells, enhance the activity of osteoblasts, inhibit the activity of osteoclasts, regulate estrogen levels, and achieve the effects of preventing and treating osteoporosis. It mainly regulates Wnt/β-catenin, Notch, PI3K/Akt and other signaling pathways. The mechanism of Achyranthis Bidentatae Radix in the treatment of OP shows the characteristics of multi-component, multi-target and multi-pathway.

Hydrofluoric acid inhalation injury is difficult to treat, despite it has low incidence. It could cause mild symptoms such as cough and sore throat, or severe symptom that may develop into life-threatening acute respiratory distress syndrome, and even rare pulmonary diseases such as reactive airway dysfunction syndrome and pulmonary alveolar proteinosis. Currently, there is no specific standard for the diagnosis and treatment of hydrofluoric acid inhalation injury. Authors summarize the incidence, injury mechanism, clinical diagnosis and treatment of hydrofluoric acid inhalation injury by searching literature at home and abroad and propose that pulse contour cardiac output monitor and extracorporeal membrane oxygenation have great application prospects in treatment of severe cases, so as to provide references for peers.

PURPOSE: We compared the treatment results and toxicity in nasopharyngeal carcinoma (NPC) patients treated with concurrent chemotherapy (CCRT) alone (the CRT arm) or neoadjuvant chemotherapy followed by CCRT (the NCT arm). MATERIALS AND METHODS: A multi-institutional retrospective study was conducted to review NPC patterns of care and treatment outcome. Data of 568 NPC patients treated by CCRT alone or by neoadjuvant chemotherapy followed by CCRT were collected from 15 institutions. Patients in both treatment arms were matched using the propensity score matching method, and the clinical outcomes were analyzed. RESULTS: After matching, 300 patients (150 patients in each group) were selected for analysis. Higher 5-year locoregional failure-free survival was observed in the CRT arm (85% vs. 72%, p=0.014). No significant differences in distant failure-free survival (DFFS), disease-free survival (DFS), and overall survival were observed between groups. In subgroup analysis, the NCT arm showed superior DFFS and DFS in stage IV patients younger than 60 years. No significant difference in compliance and toxicity was observed between groups, except the radiation therapy duration was slightly shorter in the CRT arm (50.0 days vs. 53.9 days, p=0.018). CONCLUSION: This study did not show the superiority of NCT followed by CCRT over CCRT alone. Because NCT could increase the risk of locoregional recurrences, it can only be considered in selected young patients with advanced stage IV disease. The role of NCT remains to be defined and should not be viewed as the standard of care.
