The therapy of removing beat and toxic,strengthening the body to cultivate the fundamental is the mainstream of treating cancer in traditional Chinese medicine up to now,and the therapy of warming yang has been rarely involved.While the pathogenesis of tumor is spleen and kidney yang deficiency in root,and phlegm,stasis,and poison entangled with each other at the secondary position; the main therapeutical principle of tumor is simultaneous application of purging-tonifying therapy while focusing on protecting yang.The author believes that the treatment of cancer should pay attention to the whole concept,especially warming yang for patients with advanced tumors.The therapy of warming yang is an effective way to get rid of phlegm and blood stasis.Patients after radiotherapy and chemotherapy should be paid more attention to warming yang.

Renal cancer is a common malignant tumor in urology, with complicated pathogenesis and no obvious clinical symptoms. Metastatic renal cancer accounts for 20%-30% of the newly diagnosed renal cancer. The 5-year survival rate for metastatic patients is less than 10%.At present, the main non-surgical treatment means of mRCC include cytokines and targeted drug therapy, and immunotherapy has also become a research hotspot of mRCC. The current status and research progress of mRCC therapy were reviewed. The medical treatment methods of metastatic renal cancer, such as receptor tyrosine kinase inhibitors and mTOR inhibitors; immunotherapies, such as immunosuppressants for PD-1/PD-L1 were also discussed.

OBJECTIVE:To optimize the preparation technology of Compound bovis calculus sativus gel. METHODS:The ul-trasonic emulsifying technology was optimized by orthogonal test using ultrasonic power,ratio of ultrasonic time to interval time, total ultrasonic time as factors,using centrifugal stability constant(KE)as index.Ultrasonic emulsifying method was applied to pre-pare O/W emulsions using paeonol,berberine hydrochloride and eucalyptus oil;then calculus bovis sativus powder was added into O/W emulsions,and then mixed with carbomer(940)gel matrix to prepare gel. The formulation of gel was optimized by orthogo-nal test with the amount of carbomer (940),glycerool and triethanolamine as factors,using compactibility score,comprehensive score of release rate in vitro as index. Validation test,stability test and content determination of bilirubin were conducted for gel pre-pared by optimized technology. RESULTS:The optimal ultrasonic emulsifying technology was as follows as ultrasonic power 450 W,ratio of ultrasonic time to interval time 2:1,and total ultrasonic time 5 min. The optimal formulation of gel was as follows as carbomer(940)0.5%,glycerool 15%,triethanolamine 0.20%(g/100 g). The average of KE of validation test and average compre-hensive score were 0.175 and 98.67(RSD<2%,n=3);the appearance of the preparation had no obvious change in stability test, and average percentage of bilirubin in labeled content was 100.8%. CONCLUSIONS:The optimal formulation and preparation tech-nology of gel is feasible,and the prepared gel is stable and controllable in quality.

Objective To observe and identify the impact of a type of macro?pore bone block bioactive glass on osteo?blast in vitro. Methods Extract fluid of new bioactive glass was prepared withα?MEM culture medium as the bioactive medium group. And the concentrations of different ions were detected with Inductively Coupled Plasma?Atomic Emission Spectrometry in bioactive medium group andα?MEM medium group. MC3T3?E1 cells cultured in bioactive medium group were considered as ex?perimental group and cells cultured inα?MEM medium as control group. Giemsa and immunofluorescence staining was performed to detect the cell numbers, the karyoplasmic ratio and the average fluorescence intensity per cell. Cell proliferation and viability in different groups were detected by cell cycle analysis, MTT assay and BrdU assay, respectively. Total RNAs of cells in different groups were extracted and the expressions of ALP, OCN and collagenⅠwere measured by quantitative real time PCR. ALP stain?ing and alizarin red staining were performed to assess the differentiation and mineralization of MC3TC?E1 cells in different groups. Results The concentrations of Si and F were 40.02 ± 0.67 mg/L and 0.02 ± 0.001 mg/L in bioactive medium group, higher than 2.02±0.01 mg/L and 0.00 mg/L inα?MEM solution, and the concentration of Ca was lower than that inα?MEM solution. The con?centration of P and Na had no difference. In Giemsa staining, the cell number in 400 times field under a microscope was 106.0 ± 6.025 in bioactive medium group and 40.20 ± 3.639 inα?MEM medium group. In the immunofluorescence of vinculin, the karyo?plasmic ratio and the expression of vinculin were higher in bioactive medium group (40.85±5.720, 0.050 88±0.021 78) than inα? MEM medium group (21.93 ± 4.137, 0.023 60 ± 0.003 18). In cell cycle analysis, the proportion of cells retained in S and G2/M phase in the bioactive medium group was more than that in theα?MEM medium group after 72 hours of cell culture. In the BrdU and MTT assay, MC3T3?E1 cells in bioactive medium group both showed a higher proliferation rate with statistical significance. In MC3T3?E1 cells cultured with the bioactive medium, the expressions of osteogenesis?related genes were higher than those cultured with ordinaryα?MEM solution;in the ALP staining and alizarin red staining, the expression of ALP and the mineralization rate were higher in bioactive medium group (1.328%±0.015 36%, 2.953%±0.536 3%) than inα?MEM medium group (0.979%±0.030 59%, 1.000%±0.208 1%). Conclusion The bioactive medium promotes cell proliferation and osteoblastic differentiation of MC3T3?E1 cells, and has much more Si ions, which indicates that macro?pore bone block bioactive glass can promote cell proliferation and dif?ferentiation and has promising bioactivity.

Objective To investigate the effect of super-selective intracoronary administration on acute myocardial in farction patients.Methods A total of 240 patients with ST-segment elevation myocardial infarction who received emergency percutaneous coronary intervention in our department from March 2012 to January 2014 were selected and divided into the intravenous drug administration group (n=77),the conventional intracoronary drug administration group (n=81) and the super-selective intracoronary drug administration group (n=82).Parameters,including the Thrombolysis in Myocardial Infarction (TIMI) classification,ST segment resolution after operation,peak values of creatine kinase MB (CK-MB) and troponin-I (cTn-I),left ventricular ejection fraction,left ventricular end-diastolic diameter (LVEDD),major adverse cardiovascular events and bleeding events,were compared between the groups.Results There were no significant differences in TIMI flow grade between the three groups (x2 =0.14,P=0.529).The percentage of patients with complete ST segment resolution after operation was higher in the super-selective intracoronary drug administration group than in the intravenous drug administration and conventional intracoronary drug administration groups (74.4％ vs.62.3％,61.7％,x2 =8.24,P＜0.05).Peak values of CK-MB and cTn-I were lower in the super-selective intracoronary drug administration group than in the other groups (P＜0.05).There were no significant differences in left ventricular ejection fraction and LVEDD between the three groups after operation,but left ventricular ejection fraction and the incidence of angina pectoris significantly improved in the super-selective intracoronary drug administration group than in the other groups after a three month follow-up (P＜0.05).There were no significant differences in target lesion revascularization,nonfatal myocardial infarction and druginduced thrombocytopenia between the three groups (P ＞ 0.05).Conclusions Super-selective intracoronary drug administration can significantly enhance cardiac function and alleviate angina pectoris in patients with acute myocardial infarction,and should be a recommended method.

Objective To investigate the pathological distribution and clinical characteristics of pineal region tumors (PRTs) with variant pathology.Methods We retrospectively analyzed the clinical and pathological data of 133 patients with PRTs that were performed surgical removal from January 2000 to January 2009 in our hospital.Results Sixty-one patients (45.9%) were diagnosed as having germ cell tumors,17 (12.8%) pineal parenchymal tumors,28 (21.1%) gliomas and 27 (20.2%)other resource tumors.Sex ratio of patients with germ cell tumors,pineal parenchymal tumors and gliomas were 14.25:1 (male:female),2.4:1 and 1.15:1,respectively; their median ages were 15.3,24.7 and 28.1,respectively.The serum immunologic test showed abnormal results in 33 patients; except for 1 with metastatic tumors,the others were diagnosed as having germ cell tumors.Conclusion PRTs have many pathological types and patients with PRTs are mainly diagnosed as having germ cell tumors.Correct diagnosis can not be made by imaging,serum immunologic test or biopsy, thus,obtaining complete clinical specimen during the total tumor removal is very necessary in studying the pathology of PRTs.

AIM: To study the pathological change in mouse organs immunitied by inactivated SARS-CoV vaccine. METHODS: Inactivated SARS-CoV vaccine was injected into BALB/c and C57BL/6 mice. Anti-SARS antibody was analyzed by ELISA. After 8 weeks, the immunitied mice were killed and those organs were analyzed by pathological methods. RESULTS: Anti-SARS antibody in mice was positive after 8 days. Only minimal injury was observed in a few lungs and livers, but the other organs were not. CONCLUSIONS: Inactivated SARS-CoV vaccine induced mice to create antibody, whereas they did not cause severe injury. This result will be valuable for vaccine into clinical research. [

OBJECTIVETo study the effect of enteral nutrition as replacement of mechanical bowel preparation on peritoneal and intraluminal disseminated tumor cells, recurrence and metastasis in patients with colorectal cancer.

METHODSA total of 120 colorectal cancer patients between March 2007 and December 2011 were enrolled prospectively and randomly divided into two groups. Group A (n=60) received preoperative bowel preparation with enteral nutrition fluid (30 ml·kg(-1)·d(-1)), without enema, taxative or antibiotics. Group B (n=60) underwent traditional intestinal preparation consecutively 3 days before operation, including fasting, oral antibiotic, and cleaning enema. All the patients received peritoneal lavage with 400 ml of normal saline at the time of laparotomy and 200 ml of the lavage fluid was collected. All the cases underwent distal colorectal lavage with 1000 ml of normal saline before anastomosis, and 500 ml of the lavage fluid was collected. Fluid samples were quickly sent for exfoliated cytological examination. The positive rates of exfoliated cancer cell in peritoneal cavity and intraluminal cavity, postoperative complication, recurrence and metastasis were compared between the two groups.

RESULTSIn group A, exfoliated cancer cells were found in 5 of 60 cases (8.3%) in peritoneal lavage fluid and in 9 of 60 cases (15.0%) in distal colorectal lavage fluid, while in group B, cancer cells were found in 13 of 60 cases (12.5%) and 19 of 60 cases (31.7%) respectively. There were significant differences between group A and B (P=0.041, P=0.031). Fifty-five patients in group A were followed up from 16 to 46 months after surgery, as well 57 patients in group B. Rates of local recurrence and distant metastasis in Group A and B were 5.5% vs. 7.0% and 10.9% vs. 10.5% respectively. There were no significant differences (P=0.733, P=0.984). There was no significant difference in 3-year survival rate between the two groups (80% vs. 78%, P=0.312).

CONCLUSIONSEnteral nutrition instead of traditional bowel preparation can decrease the positive rate of disseminated cancer cells in peritoneal cavity or colorectal lumen, while dose not affect recurrence and metastasis rates in patients with colorectal cancer.
