Objective To evaluate the survival and adverse effects of adjuvant concurrent temozolomid (TMZ) combined with radiochemotherapy in postoperative patients with high grade intracranial glioma.Methods 84 postoperative patients with high grade intracranial glioma were randomly divided into the observation group (42 cases including 25 grade Ⅲ cases and 17 grade Ⅳ cases) and the control group (42 cases including 23 grade Ⅲ cases and 19 grade Ⅳ cases).All patients were treated with concurrent radiochemotherapy after surgical operations,the total radiation dose was 60-66 Gy.The patients in observation group were given daily oral TMZ 75 mg/m2 during radiotherapy.4 weeks after radiotherapy,all of the patients received 6 cycles of TMZ,each cycle lasted 5 days with 28 days interval between each cycles.150 mg/m2 of TMZ was given for the first cycle for 5 days,followed by 200 mg/m2 of drug for the rest of the cycles if no significant drug related toxicities were observed.Results The overall response rates (CR+ PR) were 71.7 ％ (33/46) in the observation group,and 32.6 ％ (15/46) in the control group,and with significant difference between the two groups (P ＜ 0.001).The 1,2 and 3 year survival rates of patients in the observation group were 71.7 ％,47.8 ％,36.9 ％,and 56.5 ％,26.1％,15.2 ％ in the control group.The significant differences were found in 2-year and 3-year survival rates between the two groups (P =0.031,0.018).The median recurrent period in the observation group were 22 and 12 months in the control group,and with singnificant difference (P =0.015).The main side effects were limited to grade Ⅰ or Ⅱ.Conclusions Concurrent TMZ combined with radiotherapy in the treatment of high grade gliomas has better clinical efficacy,and can improve the 2-year and 3-year survival rates.Patients tolerate the strategy well and no severe toxicities are observed.

OBJECTIVE: To establish regression model between craniofacial lines and body height by measuring craniofacial lines in Southwest Han males using CT and to accumulate data for the study of forensic anthropology. METHODS: Head CT data of 273 Han males in Southwest were collected and 7 craniofacial lines were determined. Multiplanar reconstruction and volume rendering were performed by image post-processing software and the selected lines were measured. The relationship between each measuring indicator and body height was analyzed using SPSS 21.0 software. The regression equation of body height estimation was established and 50 samples were selected again and put into the mathematics models to verify its accuracy. RESULTS: The linear regression equations of 7 lines were established (P < 0.05). The correlation coefficients of the unary linear regression equations were 0.190-0.439 and the standard errors of the estimate (SEE) were 4.597-5.023 cm. The correlation coefficients of the multiple linear regression equation were 0.494-0.524 and the SEE were 4.418-4.458 cm. The return tests showed that the highest ± 1SEE accuracy of the multiple regression equation: y = 83.959+3.589 x6+2.573 x2, were 30%; and the highest ± 2SEE accuracy of the multiple regression equation: y = 72.646+3.316 x6+1.586 x2+1.553 x4+2.211 x3, were 92%. CONCLUSION There is significant linear correlation between 7 selected lines and the stature in this study, and the plural linear regression equation established could be applied for estimating the stature of Southwest Han males.

OBJECTIVETo explore the pathomorphological change of the atlanto-occipital segment of vertebral artery (V3 part) related with cervical vertigo.

METHODSFrom June 1999 to November 2011, the pathomorphological change of the atlanto-occipital segment of vertebral artery were observed in 1680 patients with cervical vertigo using 3D-CTA technology. The clinical data of these patients were analyzed. There were 783 males and 897 females, aged from 22 to 70 years old with an average of 52.8 years old. Doppler examination showed vertebral basilar artery flow velocity to speed up or slow down.

RESULTSThe blood vessel of 3360 branches were detected in 1680 patients and 2778 branches were detected out vascular anomaly. And 829 branches were in V1 segment, 421 were in V2, 328 were in V3, 1190 were in V4. The pathomorphological changes in the atlanto-occipital segment (V3) of vertebral artery included angiospasm, congenital absence, abnormal exit, localized stenosis.

CONCLUSIONThere are 4 kinds of pathomorphological changes in the atlanto-occipital segment of vertebral artery related with cervical vertigo. The 3D-CTA result can be used to judge prognosis and adopt reasonable treatment for the patients.

A comparable study were carried out by determination of trace elements on five marine-derived shell traditional Chinese medicine (TCM) (Ostreae Concha, Haliotidis Concha, Margaritifera Concha, Meretricis Concha, and Arcae Concha), which were recorded in the Chinese Pharmacopoeia (2010 version). Seven trace elements in 51 batches of this type of shell TCM were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS), combined with principal component analysis (PCA) methods. The content of element Se, which exhibited significant differences among different drugs, could be used as a key element to distinguish this type of drugs. Meanwhile, the contents of elements Co, Cu, Mo, and Ba in Haliotidis Concha, Co and As in Margaritifera Concha, Mo and As in Meretricis Concha, Mo, As, and Ba in Arcae Concha, and Zn in Meretricis Concha were relatively stable. In the PCA plot, Arcae Concha and Meretricis Concha could be efficiently distinguished from Ostreae Concha together with Haliotidis Concha, and Margaritifera Concha. The results also showed a correlation with their medicinal function. In conclusion, trace elements in marine-derived shell TCM could not be neglected for their quality control.

BACKGROUND: Some clinical randomized controlled trials are trying to answer the clinical effects of SuperPATH approach and traditional approach in hip replacement, but the conclusions of present studies are different. OBJECTIVE: To compare the clinical outcomes between SuperPATH approach and traditional approach in hip arthroplasty. METHODS: The randomized controlled trials about SuperPATH approach and traditional approach in hip arthroplasty published before July 2017 were searched in the PubMed, EMbase, EBSCO, Cochrane Library, and CNKI. Some published references were hand-searched. Two reviewers independently screened the literatures, extracted the data and evaluated methodological quality. Meta-analysis was conducted by Revman 5.3 software. RESULTS AND CONCLUSION: Eight randomized controlled trials (involving 483 cases) were involved in this analysis. The SuperPATH approach group consisted of 228 cases; the traditional approach group consisted of 255 cases. Meta-analysis results demonstrated that compared with traditional approach group, operation time was longer; incision was shorter; hip joint score was higher at postoperatively 3 months; Visual Analogue Scale scores were lower at postoperatively 1, 3 and 7 days; intraoperative blood loss and postoperative drainage volume were less in the SuperPATH approach group. No significant difference was found in postoperative complications, postoperative anteversion angle, and postoperative abduction angle, and hip score at postoperatively 1 and 6 months. These findings suggested that the total short-term effects in SuperPATH approach was better than that of traditional approach in hip arthroplasty. Long-term clinical outcomes require further investigation.

Objective To explore the effects of endoplasmic reticulum stress response(ERS) and its related apoptosis on dopaminergic neurons death.Methods NGF treated-PC12 cells were treated with 6-OHDA,MPP+ and rotenone.MTT assay and flow cytometry were used to measure the cell viability and the rate of cells apoptosis induced by those neurotoxins at different concentrations and times.The expressions of ERS-related gene XBP1,Grp78,CHOP,caspase-12 in drug-treated group and reserpine preincubation group were determined by RT-polymerase chain reaction(RT-PCR) and immunohistochemistry.Results After exposing to different concentration toxins,the vitality of PC12 cells was decreased by 52% at 100?mol/L 6-OHDA,by 44% at 75?mol/L MPP~+,and by 40% at 20 nmol/L rotenone for 24 hours respectively and ws decreased in a dose dependent manner. FCM assay confirmed time-dependent cell apoptosis.The apoptotic cells ratio of 24 h groups were (31.22?3.21)%,(27.46?2.35)%,(29.26?2.53)%,respectively(P＜0.01).In 6-OHDA groups,the gene expressions of XBP1,Grp78 were approximately 2-fold increased after 8 h exposure, CHOP reached peak level at 16 h(149.5?3.3% vs 35.9?1.8%,P＜0.01).The transcription level of caspase-12 was significantly higher than normal control at 16h[(95.4?2.8% vs(23.8?3.0)%, P＜0.01],but was alleviated by reserpine prcincubation(62.15?4.3%,P＜0.05).The increased expressions of Grp78 and CHOP after drug exposure were confirmed by immunochemistry stain.The similar results were observed in MPP~+ and rotenone groups.Conclusions The excessive ERS and ERS-activated cell apoptosis pathway may be involved in selective death of dopaminergic neurons.
