Lysosomes are acidic catabolic organelles,containing over 50 acid hydrolases and many lysosomal specific membrane proteins.Lysosomes are responsible for the disposal and recycling of worn out and damaged cellular macromolecules and organelles as well as the digestion of extracellular and foreign materials delivered to them by endocytosis,autophagy and phagocytosis.Increased expression and function of various lysosomal hydrolases are common in human tumors,and they often correlate with a higher risk of rccurrence and poor prognosis.Inhibition of lysosomal exocytosis can inhibit tumor invasion and metastasis.It does not affect the activity of acid hydrolytic enzymes,but causes the instability of lysosomal membrane and increases the sensitivity of tumor cells to drugs.

Antibody drug is a new kind of new anticancer drug with distinct superiorities in tumor thera-py developed in recent years.Antibody drugs can effectively kill the tumor cells with goodselectivity,and have good efficacy,lower toxicity and a specificity of distribution in vivo.They can specifically bind to tumor-associated target moleculars.Besides,the antibody drugs can effectively kill the tumor cells with drug-resistane.

In recent years,the techniques of radical cystectomy and urinary diversion are continually improving,the surgical safety and efficacy are continually increasing.From open to laparoscopic to robotic,surgical techniques are progressing,but it is not yet possible to replace each other.With the development of equipment,laparoscopic radical cystectomy (LRC) and robotic-assisted laparoscopic radical cystectomy (RARC) can further improve the perioperative efficacy,the basic principles of open surgery can be copied,their perioperative oncologic outcomes are not inferior to open surgery.RALRC seems to have more advantages in pelvic lymph node dissection,long-term oncologic outcomes of the three techniques are simnilar,and open surgery seems to have more advantages in advanced tumors.Intracorporeal construction of the urinary diversion is still the mainstream,extracorporeal is likely to be the future direction.Laparoscopy is still the most suitable minimally invasive technique of radical cystectomy according to our national conditions.

Objective To explore the relapse prevention effect of community independent skills in patients with schizophrenia.Methods 100 patients with schizophrenia from May 2014 to February 2015 were analyzed and divided into the observation group and the control group by using the computer random grouping.The standardization of community rehabilitation training was taken in the control group patients,whike independent skill training was taken in the observation group patients.The clinical curative effect of the study for a year were evaluated through SAPS, BPRS,SDSS,SANS and ITAQ for all the object.Results There was no statistical significance of ITAQ,SDSS,SAPS and SANS score difference in all the research objects before the rehabilitation treatment has (P >0.05 ).ITAQ, SDSS,SAPS and SANS score of the observation group were better than that of the control group after 8 weeks, 26 weeks and after 1 year,the difference was statistically significant(P <0.05).Recurrence rates of the observation group and control group were 16% and 40% respectively,and hospital admission rates were 10% and 32% respec-tively,the difference was statistically significant(P <0.05).The adherence were significant between the two groups (χ2 =6.92,P <0.05).Medication adherence to drug management ability were better in the observation group than the control group(χ2 =41.558,P <0.05).Conclusion The community independent skill training have an remarka-ble effect on the rehabilitation of patients with schizophrenia,and can improve the residual symptoms of schizophrenia after rehabilitation.It can help people with schizophrenia to maintain a good long-term positive effect,which is worth further clinical research and extension.

Objective:To retrospectively evaluate the prognostic risk factors of patients with gallbladder carcinoma and the effect of normal prognostic nutrition index (PNI) on the survival. Methods:We retrospectively analyzed 63 patients with gallbladder carcino-ma treated in our hospital between January 2008 and December 2012. The independent prognostic factors of the patients were calculat-ed by the Cox proportional hazards model. The benefit of normal PNI status on the prognosis was further explored in the patients using survival analysis. Results:Lymph node metastasis, PNI≤50, squamous carcinoma, liver invasion and choledoch invasion were the risk factors of overall survival (OS) in the univariate analysis, while only lymph node metastasis (HR=4.495, 95%CI 2.380~8.488, P<0.001) and PNI(HR=0.195, 95%CI 0.098~0.389, P<0.001) were the dependent influential factors of the prognosis and OS in the multi-variate analysis. The effect of PNI on OS was even more statistically significant different in the younger patients (≤65y) than in the el-der (>65y) (younger group:P=0.011;elder group:P=0.078). Conclusion:The gallbladder carcinoma patients with normal PNI status (>50) have better OS compared to the patients with PNI≤50, with statistical differences between the two. And it is more significant in the patients of the younger group (≤65y), comparing with the elder group. PNI could be taken as a potential prognostic evaluation factor for the gallbladder carcinoma patients and can provide a more comprehensive evaluation of patients' conditions to clinician.

1 case of intraductal papilloma of parotid gland was analyzed by means of clinicopathologic data,hematoxylin-eosin and immuno-histochemical staining.Combined with the relevant literature,clinical pathological features,diagnosis and treatment of the salivary gland intra-ductal papilloma were discussed.

BACKGROUND: Three-dimensional (3D) printing technology is a new rapid prototyping and rapid manufacturing technology. OBJECTIVE: Through the analysis of the related papers, the paper summarizes and discusses the research progress of 3D printing technology, the prospect of application in joint replacement and the status quo and development trend of 3D printing technology in joint replacement.METHODS: The relevant literature was retrieved by the first author with the China Journal Full-text Database (CNKI) and PubMed database from 1985 to 2015. The key words were 3D printing technology, rapid prototyping, arthroplasty, joint replacement. The included 81 articles were analyzed.RESULTS AND CONCLUSION: Basic research and clinical application of 3D printing technology and joint replacementtechnology are becoming more and more popular. 3D printing further optimizes in the communication and teaching in joint replacement, and avoids intraoperative and postoperative complications. According to the needs of different teaching materials, 3D printing can print out different parts of the real body with different characteristics of print by 3D printer. The surgical simulation exercises with 3D limb printing different materials are the best way to improve theoperation skills. 3D printing technology in the osteotomy guide precision has basically completed multicenter clinical trial,and toward to the clinical application of small scale stage. The construction of individualized treatment plan and theapplication of active biological organs by 3D printing technology will become the new research direction of jointreplacement.

Objective To investigate the role of IP-10 in the pathogenesis of ankylosing spondylitis (AS). Methods The peripheral blood monocytic cells (PBMC) were collected from 39 AS patients, and the mRNA expression of IP-10, IFN-? and IL-4 were measured by semi-quantitive RT-PCR with G3PDH as the internal control. Results The mRNA expression levels of IP-10, IFN-? and IL-4 as well as the rate of IFN-?/IL-4 were elevated in the PBMC of AS patients compared with the healthy controls (P

Objective To explore the relationship between preoperative right ventricular ejection fraction(RVEF) and postoperative complications in the elderly patients with lung resection. Methods RVEF was assessed in 118 consecutive aged patients before pulmomary resection by echocardiography, 64 of whom received RVEF measurement again 3 weeks after operation. Results Preoperative RVEF in patients with postoperative complications was obviously lower than that in patients without ones. The frequency of postoperative complications in patients with different preoperative RVEF(
