OBJECTIVE:To provide reference for rational use of anti-tumor essential medicine in the clinic. METHODS:The application of anti-tumor essential medicine in 39 hospitals from Chongqing area during 2012-2014 was analyzed statistically in re-spects of consumption sum,DDDs,DDC and B/A. RESULTS:The total consumption sum of anti-tumor essential medicine in 39 hospitals from Chongqing area during 2012-2014 increased from 10 083.65 ten thousand yuan to 15 186.65 ten thousand yuan,with annual increase rate of 22.72%. 3-year total consumption sum was 37 952.45 ten thousand yuan,and the sum of consumption sum of top 10 medicines was 36 742.24 ten thousand yuan,accounting for 96.81%;top 3 medicines were paclitaxel,oxaliplatin and flu-orouracil. During 2012-2014,DDDs had changed to certain extent,and the front medicines contained tegafur,paclitaxel and cyclo-phosphamide,etc;the most increment medicine was paclitaxel (oral),whose annual growth rate was 59.63%;that of tamoxifen decreased year by year,with annual decrease rate of 5.14%. DDC of paclitaxel,oxaliplatin and etoposide were the higher others. Annual B/A of oxaliplatin,fluorouracil and cytosine arabinoside were all lower than 1.00. CONCLUSIONS:The lonsumption sum and DDDs of anti-tumor essential medicine had increased reasonably in 39 hospitals from Chongqing area during 2012-2014,while their DDC had kept stable. Main medicines used in the clinic are suitable for numerous indications,and are expensive.

Objective To observe the efficacy of local gene transfection in CD154 extracellular domain on the survival of renal allografts. Methods The kidneys of Brown Norway (BN) rats were transfected with CD154 extracellular domain gene recombined adenovirus. The transfected kidneys were transplanted to Lewis rats (transfection group). BN→Lewis kidney transplantation with non transplanted kidneys served as the controls. The allograft survival time and the allograft function between the two groups were compared. Results The allograft survival time of the transfection group was longer than that of the controls significantly [(28?7.3)d vs (8.6?1.2) d, P

ObjectiveTo explore the feasibility of mediating recipient lymphocyte reaction with donor dendritic cells (DCs) in renal allograft recipients to guide individualized inmunosuppressive therapy. Methods From Jan. 2008 to Jan. 2010, 30 recipients received living related kidney transplantation were successively and divided into 2 groups according to the strategies of the correction of the dosage of immunosuppressant, 15 in each group. The strategy of immunosuppressive therapy in both groups was Tac + MMF + Pred. The correction of the dosage of immunosuppressant in experimental group was conducted by recipient lymphocyte reaction with donor DC (LR) combined with Tac and MPA blood concentration monitoring. Only blood concentration monitoring of drugs was applied in control group. Examinations of liver and renal function, blood and urine routine as well as blood sugar were done monthly for 1 year. ResultsDuring the follow-up period, the rate of acute rejection in experimental group and control group was 13. 3 ％ and 46. 7 ％ respectively (P＜0. 05) ;the rate of infection in experimental group and control group was 6. 7％ and 40. 0％ (P＜0. 05)respectively; the adverse reaction rate in experimental group and control group was 13. 3％ and 46. 7％(P＜0. 05). There was no significant difference in the serum creatinine level between the two groups at each observation point. ConclusionThe application of combined recipient LR with donor DC and blood concentration monitoring of drugs in individualized irnmunosuppressive therapy is more comprehensive and accurate.

Objective To explore the feasibility of mediating recipient lymphocyte reaction with donor dendritic cells (DCs) in renal allograft recipients. Methods Donor bone marrow monocytes (BMMCs) were isolated and cryopreserved in liquid nitrogen before kidney transplantation. At 0 day, 1month,3 month, 6 month and 9 month post-operation, CD34+ cells which were isolated from frozen BMMCs and cultured into DCs as well as the peripheral blood lymphocytes (PBLs) of donors were used as the stimulating cells to the PBLs of recipients and healthy volunteers. The number of viable DCs from frozen- and room temperature-preserved BMMCs was counted and the reactions of recipients'and healthy volunteers' lymphocytes to DCs and donor PBLs were measured. Results 6. 8 × 107BMMCs were isolated from each 10 ml of donor bone marrow on average while (4. 10 ± 0. 58) × 105CD34+ cells were isolated by magnetic active cell sorting (MACS). There was no significant difference in the isolating rate of recovered CD34+ cells at each observation point postoperatively. The percentage of viable BMMCs and CD34+ was decreased significantly at 1 month after surgery, then, decreased slowly and progressively. The decreasing rate of BMMCs was higher than CD34+. The rate of viable DCs was maintained stable (93. 2%-94. 8% ) in each group. The reactions of recipients' and healthy volunteers' lymphocytes to DCs were stronger than those to donor PBLs (P＜0. 05). The reactions of healthy volunteers' lymphocytes to DCs were maintained stable while those of recipients' were fluctuating. Conclusion Bone marrow-derived DCs are superior to PBLs in mediating long-term lymphocyte reaction after kidney transplantation due to their stable viability and stimulating ability to lymphocytes. Only once collection of a small quality of bone marrow of donors is needed to meet the demand of immune monitoring at any time after transplantation.

Objective To investigate the characteristics of patients with non-syndromic cleft lip with or without cleft palate (NSCL/P),and to provide the basis for the treatment.Methods 1435 cases of NSCL/P were collected from January 2012 to December 2014.Characteristics of the gender,type and side,blood type,associated malformation,genetic history of the patients were analyzed retrospectively.Results In the 1435 cases,397 cases (27.67％) presented with cleft lip,655 cases (45.64％) with cleft palate,and 383 cases (26.68％) with cleft lip and palate.801 (55.82％) were male,and 634 (44.18％) were female.In cleft lip,male 60.20％ (n=239) were more than female 39.80％ (n=158);left side was 57.43％ (n=228) more than right 27.96％ (n=111) and the right were more than bilateral 14.61％ (n=58).In cleft lip and palate,male 78.33％ (n=300) were more than female 21.67％ (n=83),left 41.51％ (n=159) were more than right 28.20％ (n=108) and bilateral 30.29％ (n=116).In cleft palate,female 60.00％ (n=393) were more than male 40.00％ (n=262).Blood type AB with cleft lip (28/369) were higher than ones with cleft palate (28/627).All of the differences were statistically significant (P＜0.05).5.09 ％ (n =73) patients with malformation were found out of 1435 cases.The patients with congenital heart disease (n=36,2.51％) was the largest number of total deformity.Conclusions In patients with cleft lip,male is more than female;left side is more than right;unilateral clefts are higher that bilateral ones.In cleft lipand palate,male were more than female,left side were higher.In cleft palate,female were more than male.Blood type AB with cleft lip is higher than that of cleft palate.

Objective To evaluate the efficacy and safety of retroperitoneal laparoscopic pyelolithotomy ( RLP) combined with holmium laser lithotripsy under flexible cystoscopy in the treatment of complicated nephrolithiasis. Methods The retrospective analysis was made on the clinical data of 37 patients who underwent RLP and holmium laser lithotripsy under flexible cystoscopy for complicated nephrolithiasis from January 2013 to January 2014. The clinic parameters involved basic data of patients,operational time,blood loss,post-operative hospital stay,the status of stone-free,perioperative complications,and the follow-up data of patients were observed. Results No patient was converted to open surgery. The mean stone size was (2. 8 ± 0. 9) cm in diameter,operational time was (89 ± 24) min,blood loss was (21. 3 ± 7. 7) mL,post-operative hospital stay was (6. 8 ± 1. 7) d,the stone removal rate in one session was 94. 6%. One case occurred urinary leakage,1 case occurred fever after operation,who were all recovered through conservative treatment. All cases were followed up at the sixth months after operation. Conclusion RLP combined with holmium laser lithotripsy under flexible cystoscopy is effective and safe for the treatment of com-plicated nephrolithiasis.

Background and purpose: The incidence of breast cancer increases as patients age, elderly patients account for a large proportion. Due to the insufifcient systemic therapy, more complications and poorly physical condition, the prognosis of elderly patients is often worse than the younger. The aim of this study was to investigate the safety and tolerance with non-anthracyclin regimen as adjuvant chemotherapy in elderly breast cancer patients. Methods:From Nov. 2008 to Jan. 2012, 56 patients (≥65 years) after surgical excision were enrolled into this study. The patients were divided into two groups:TC and PC groups. Each patient received 4 or 6 cycles of chemotherapy of PC (175 and 600 mg/m2, respectively;n=21) or TC (75 and 600 mg/m2, respectively;n=35), administered intravenously every 3 weeks, as adjuvant chemotherapy. Radiation therapy (as indicated) and endocrine therapy, for patients with hormone receptor-positive disease, were administered after completion of chemotherapy. Results: In this study, 50 patients completed chemotherapy as plan, the proportion of two groups were above 90%. After a median follow-up of 33 months, the median disease-free survival(DFS) and overall survival(OS) were not reached. The relapse-free rate and survival rate were 89.5%and 100%in the PC regime group, which were 90.3%and 96.8%in the TC regime group. Major toxicities included:neutropenia, leucopenia, alopecia, nausea, vomiting and various degree of peripheral neuropathy. The incidence of gradeⅢ-Ⅳneutropenia was 76.2%in PC group vs 48.6%in TC group (P=0.044). The most common cause for withdrawing from treatment was to be unable to tolerate the adverse effects. Conclusion:Adjuvant chemotherapy with paclitaxel and cyclophosphamide is safe, tolerable and promising for elderly breast cancer patients.

OBJECTIVE:To investigate the effects of long-term use of calcium channel blocker-Diltiazem(Dil)on the dosage of ciclosporin A and renal function of renal graft recipients.METHODS:Dil was administed in67renal graft recipi?ents,meanwhile who were orally taking CsA with another59renal graft recipients served as controls.The dosages of ci?closporin A of2group were adjusted to the level within therapeutic window,then the dosage of CsA and serum creatinine change of the2groups36mo after drug administration were observed.RESULTS:12mo,24mo and36mo after operation,the synchronized cyclosporin A dosages in Dil group were lower than the control group respectively by14353mg,9656mg and7817mg.No significant differences were found in serum creatinine levels between the2groups within the first12mo after operation.Thereafter,the creatinine levels in the control group has a faster increase and the creatinine level in Dil group was significantly lower than that of the control group18mo～36mo after operation(P

Objective:To evaluate the efficacy and safety of capecitabine-based regimens in treating patients with liver metastases from breast cancer. Methods:A total of 163 patients with liver metastases from breast cancer who received capecitabine-based regimens between January 1, 2000 and Dec 31, 2011 were retrospectively reviewed. The clinicopathological characteristics and treatment outcomes of these patients were evaluated. Results:Of the 163 patients retrospectively analyzed, 109 received docetaxel plus capecitabine (TX) and 54 received vinorelbine plus capecitabine (NX). TX treatment achieved objective responses in 59 patients (54.1%), including complete response in four patients, partial response in 55 patients, and stable disease in 25 patients. In patients who received NX, the objective response and clinical benefit rates were 50.0%and 70.4%, respectively;one patient had a complete response, 26 patients had a partial response, and 11 patients had a stable disease. The safety profiles of TX treatment were more favorable and predictable compared with NX treatment, with a low incidence of grade 3/4 adverse events in hematological and non-hematological toxicities. Results showed that median overall survival after liver metastases (LMS), progression-free survival (PFS), and post-metastasis survival (MSR) were 26, 8, and 28 months in the TX arm. LMS, PFS, and MSR were longer in the TX arm than in the NX arm. Conclusion:Capecitabine-based regimens showed tolerance in patients with liver metastases from breast cancer. TX treatment had a tendency of lower toxicity and was more effective compared with NX treatment.

OBJECTIVETo Verify the safety and reliability of one-stage repair of complete cleft Lip and palate in infancy and to obtain the primary result.

METHODSThe simultaneous repair of complete cleft Lip and palate in infants 3 to 12 months of age were performed in 271 cases. The deformities include 185 cases of typical complete unilateral clefts and 75 cases of complete bilateral clefts, and other 11 atypical cleft infants. The preoperative orthopedic treatment for wide alveolar cleft was undertaken in 24 infants and the lip appearance and speech outcome were evaluated in 116 children by 1 to 4 years' postoperative follow-up.

RESULTSAll infants, except for dyspnea in 2 babies, palatal fistula formation in 6 cases and temporary wound hemorrhage in 5 infants, were recovered without complications. After orthopedic treatment, the width of the alveolar cleft was reduced 6.1 mm in average. The evaluation showed that 93.1% of children had got good or excellent lip appearance. And the acceptable or excellent speech was found in 94.8% children.

CONCLUSIONSSimultaneous repair of complete cleft lip and palate in infancy is safety and reliable. The preoperative orthopedic procedure is able to reduce the wide alveolar cleft and to achieve alignment of alveolar segments. The acceptable and or excellent lip appearance and speech function could be obtained in this one-stage operative procedure in infants.
