Next we analyze the cause of tumor resistance to chemotherapy and radiotherapy. And finally,We discuss the three antitumor strategies targeting hypoxia, which opens a new path to conquer cancer.[

Protein degradation is fundamental to cell viability,selective elimination of regulatory proteins in the cell is an effective mechanism for regulating vital cell processes.Rapid proteasomal protein degradation is key to activation of repression of many cellular processes,including cell-cycle progression and apoptosis.Bortezomib as a proteasome inhibitor has been approved by FDA for multiple myeloma treatment.This review summarizes current knowledge of the structure and function of the proteasome and its targets.In addition,preclinical findings obtained with Bortezomib are reviewed,and existing clinical data on Bortezomib are presented.

Objective To evaluate the efficacy of intravitreal injections of conbercept in choroidal neovascularization (CNV) secondary to pathologic myopia (PM).Methods A retrospective case series of 37 eyes of 37 patients affected with CNV secondary to PM treated by intravitreal injections of Conbercept.All the patients were examined with best-corrected visual acuity (BCVA) of Early Treatment Diabetic Retinopathy Study (ETDRS) chart,central macular thickness (CMT) of optical coherence tomography (OCT) at baseline.The initial average letters of ETDRS BCVA was 49.86±8.87,CMT was (306.38±31.01) μm.All eyes were treated with intravitreal Conbercept 0.05 ml (10 mg/ml).Follow up visits were performed monthly after injection.The mean follow-up time was 16.8 months.Injections were repeated according to the situation of BCVA,CMT,subretinal fluid and CNV leakage in follow-up.All eyes received an average of 4.8 injections.BCVA,CMT and ophthalmoscope examination were assessed monthly.The relationship of BCVA improvement and CMT reduction with the data at baseline and number of treatments were analyzed by Spearman Rho correlation respectively.Results During the 1,3,6 and 12 months after treatment,the mean BCVA were all improved with statistically significant difference (t=17.629,P＜0.01).At 12 months,15 eyes (45.9％) had improvement of 15 letters or more,32 eyes (86.5％) had improvement of 5 letters or more,and 1 eye (2.7％) had decreased more than 5 letters.During the 1,3,6 and 12 months after treatment,the mean CMT were all decreased with statistically significant difference (F=43.726,P＜0.01).At 12 months,the retinal fluid of 34 eyes (91.9％) were absorbed completely;33 eyes (89.2％) had angiographic closure at that time.There was no significant relevance between BCVA improvement and sex,age and course of the disease (P＞0.05),but a significant negative correlation was found between the BCVA improvement and BCVA at baseline,injection times (P＜0.05).There was no significant relevance between CMT reduction and sex,age,course of the disease and injection times (P＞0.05),but a significant positive correlation was found between CMT reduction and CMT at baseline (P＜0.05).There were no systemic or ocular serious side effects during the follow up.Conclusions Intravitreal injections of Conbercept showed BCVA improvement and CMT reduction.It appeared to be effective and safe for choroidal neovascularization secondary to pathologic myopia.Intravitreal Conbercept for CNV secondary to PM showed BCVA improvement,CMT reduction and safety.

Objective To evaluate the association between C-reactive protein (CRP) blood levels and specific survival time of non-small cell lung cancer (NSCLC) patients treated with chemotherapy.Methods Data from 96 advanced (stage ⅢB/Ⅳ) NSCLC patients were analyzed.All patients were divided into two groups based on the enrolled time as follows the initial treatment group (48 cases) and retreatment group (48 cases).According to 0.6 mg/L and 7.3 mg/L of CRP which were the 1/3 and 2/3 of CRP concentrations,respectively,the 96 patients were divided into low,intermediate and high groups.Kaplan-Meier and Cox proportional-hazard models were used to evaluate the relationship between the CRP level and survival time.Results After adjusting for age,sex,smoking history,histological type and stage of lung cancer,a significant relationship between CRP and survival time was observed (P ＜ 0.05).Such significant differences of survival time were also observed in both of the adenocarcinoma (P ＜ 0.001) and squamous with poorly differentiated (P =0.032) subtypes.On stratification analysis by chemotherapy status,the circulating CRP level in retreatment group was correlated well with survival time (P ＜ 0.001).However,the influence of circulating CRP levels on survival time in initial group did not reach statistical significance (P =0.296).For all patients,the hazard ratio with high CRP levels for NSCLC-specific survival was 1.15 (95 ％ CI 0.82-1.61) compared with that of low CRP levels.The hazard ratio for the initial treatment group and retreatment group were 0.52 (95 ％ CI 0.16-1.74) and 1.77 (95 ％ CI 0.73-4.26),respectively.Patients with high circulating CRP level also responded poorly to chemotherapy.Conclusion A high level of circulating CRP is associated with an inferior response and survival outcome in NSCLC patients treated with chemotherapy.

Objective To explore the relevance of high density lipoprotein cholesterol (HDL-C) level and resistance of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in advanced non-small cell lung cancer (NSCLC).Methods In a total of 87 NSCLC patients harboring EGFR mutation treated with EGFR-TKI, the correlations of pre-treatment levels of soluble HDL-C between efficacy and resistance of EGFR-TKI were analyzed by Kaplan-Meier method and Cox proportional hazard model.Results Patients with normal HDL-C (≥0.94 mmol/L) had a better disease control rate (DCR) than those with low HDL-C (＜0.94 mmol/L) [94.5 ％ (52/55) vs 65.7 ％ (21/32), P ＜ 0.001].The results of univariate analysis showed that patients with normal HDL-C had longer progress free survival (PFS) (HR =0.27, 95 ％ CI 0.164-0.444, P ＜ 0.001).The results of multivariate Cox proportional hazard model analysis with sex, pathologic histology, smoking history and mutation type showed that only HDL-C group had a significant difference (P ＜ 0.001).The same results were showed when stratified by sex and smoking history (female: P ＜ 0.001, male: P =0.002;Smoker: P ＜ 0.001, non-smoker: P =0.014).Conclusion Normal pre-treatment serum levels of HDL-C are associated with a better outcome and longer progression-free survival in NSCLC patients treated with EGFR-TKI, which may be a predictive marker for a better response.

Objective To investigate the consistent long-term clinical efficacy of the procedure for prolapsed hemorrhoids (PPH) treatment for hemorrhoids.Methods Data of 87 patients with third-and fourth-degree hemorrhoids treated by surgical procedure for prolapsed hemorrhoids were collected.In all cases,third-degree hemorrhoids in 65 cases,fourth-degree hemorrhoids in 22 cases,median followed up after PPH was (3.8 ± 0.5) years.The long-term efficacy and the occurrence of complications were followed up to assess the effect of surgical procedure for prolapsed hemorrhoids.Results In patients with third-degree hemorrhoids,bleeding recurred in 2 cases (3.1％) for again bleeding,for anal bulge in 4 cases (6.2％).In patients with fourth-degree hemorrhoids,prolapse recurred in 2 cases (9.1％) for bleeding in 5 cases (22.7％).anal bulge 3 patients (13.6％),defecation difficult in one case (4.5％),one-degree of fecal incontinence in 1 case (4.5％),no other complications found,such as anal pain,anal stenosis,foreign body discomfort and fecal urgency.The chi-square test for comparison analysis suggested that:third-degree hemorrhoids postoperative prolapse and bleeding recurrence rate was significantly lower than fourth-degree hemorrhoids.Conclusions Procedure for prolapsed hemorrhoids treatment for hemorrhoids is safe and feasible,has small trauma,little pain,and definite efficacy,fewer complications,shorter hospital stay,lower reoperation rate,etc.But the long-term efficacy for third-degree hemorrhoids is superior to the fourth-degree hemorrhoids.

BACKGROUND:At present, the incidence rates of knee joint diseases such as knee osteoarthritis, knee joint degenerative are high. The major clinical treatment is total knee replacement in the clinic, so it is necessary to evaluate the changes in stress and bone mineral density of the regions surrounding the prosthesis after replacement. ＜br> OBJECTIVE:To explore periprosthetic stress and bone mineral density and to analyze their correlation after total knee arthroplasty. ＜br> METHODS:A total of 20 cases undergoing total knee arthroplasty were chosen.The hospital for special surgery scores were used to evaluate patients’ functional recovery at 12 months after total knee arthroplasty. The periprosthetic femur was divided into four regions of interest (ROI), respectively ROI 1-4;periprosthetic tibia was divided into three regions of interest, respectively ROI 5-7. Stress surrounding the prosthesis was analyzed using three-dimensional finite element analysis at 1, 3, 6 months, 1, 2, 3 years after replacement. Simultaneously, bone mineral density surrounding the prosthesis was measured using dual-energy X-ray absorptiometry. ＜br> RESULTS AND CONCLUSION:No patients affected infection or loosening of the prosthesis. At 12 months after replacement, the score of hospital for special surgery was (90.23±2.37), which showed significant differences as compared with before replacement (39.68±1.31) (P＜0.05). The level of stress shielding was highest in ROI 5 and lowest in ROI 3. Stress shielding rate of ROI increased with statistical difference at 6 months after operation (P＜0.05). At 1, 2, 3 years after operation, shielding rate in periprosthetic femoral stress in ROI 1 decreased. Compared with 1 month after operation, the difference was statistical y significant (P＜0.05). However, shielding rate of tibial periprosthetic stress in ROI 6 increased. Compared with 1 month after operation, the difference was statistical y significant (P＜0.05). Bone mineral density after 1 month after operation had no significant decrease (P>0.05). At 3 months after operation, bone mineral density began to decline significantly (P＜0.01). The decrease was most obviously in ROI 5 and the change was least in ROI 3. After 1 year of operation, bone mineral density did not change significantly. These data indicated that changes in bone mineral density were correlated with stress shielding after total knee arthroplasty. Monitoring two variations can provide theoretical data for preventing bone loss, which provides references for clinical rehabilitation guidance.

Objective To understand the quality of malaria blood examinations in township?level hospitals,so as to provide the evidence for continuing the malaria blood examinations in the stage of post?malaria elimination. Methods A total of 64 township hospitals were investigated and 640 negative malaria blood slides were scored individually according to 10 indicators inMalaria Elimination Technical Schemein 2013 and 2014. The single and multiple indicators were calculated,and the work of blood examinations and situation of technicians were investigated. The data of malaria blood examinations and patient discovery in township hospitals of Nantong City were collected and analyzedduring the period of 2011-2014. Results Forthe single indi?cator,29.5%of the thick blood films did not reach the standard,and 35.8%of thin blood films did not reach the standard. For the multiple indicators,blood slides with more than 4 indicators below the standard(poor quality)accounted for 32.5%. From ma?laria blood examinations and malaria situation,the number of slides was 194 635 during the period of 2011-2014,and there were no local vivax malaria casesin 4consecutive years from 2011 to 2014,andlocal malaria has been effectively controlled in Nantong City. For health facilities where malaria patients initially presented,the township and village level accounted for 16.3%,and county and higher level accounted for 83.7%. Conclusions The quality of malaria blood examinations in township level hospitals of Nantong City is not high and the microscopic examination has a relatively low efficiency in the discovery of ma?laria cases. A new model for malaria blood examinations needs to be further explored.
