This article gives a profound exploration on the theoretical origin, prohibitions and mechanisms of moxibustion for heat syndrome. Based upon the ancient and modem literature, this article also gives a classified summarization on diseases of moxibustion for heat syndrome, in order to obtain a thorough understanding about the theory and clinical application of moxibustion for heat syndrome, hence to further perfect the theory of moxibustion and guide the clinical practice.

Sphingosine kinase 1 (SphK1) plays critical roles in cell biological functions. Here we investigated the effects of SphK1 inhibitor SKI II on hepatoma HepG2 cell cycle progression and invasion. Cell survival was determined by SRB assay, cell cycle progression was assayed by flow cytometry, the ability of cell invasion was measured by Matrigel-Transwell assay and protein expression was detected by Western blotting. The results showed that SKI II markedly inhibited HepG2 cell survival in a dose-dependent manner, induced G1 phase arrest in HepG2 cell and inhibited cell invasion. SKI II markedly decreased the expressions of G1-phase-related proteins CDK2, CDK4 and Cdc2 and the levels of cell invasion-associated proteins MMP2 and MMP9. The results showed that SKI II inhibited cell cycle progression and cell invasion, implying SphK1 as a potential target for hepatoma treatment.

OBJECTIVETo investigate clinical characteristics and pathological changes of tissue surrounding prosthesis after hip and knee arthroplasty.

METHODSA total of 67 patients receiving hip and knee arthroplasty were included in the study and pathological changes of the revision specimens were evaluated by microscopic examination.

RESULTSOf 67 patients, there were 25 males and 42 females (ratio of 0.6) with a mean age of 64 years. There were 42 cases of revision hip prosthesis and 25 cases of knee prosthesis. The primary causes for the revision varied, including 20 cases of infection (29.9%, within 3 months in 9 cases,3 to 24 months in 3 cases and over 24 months in 8 cases), 14 cases of pain (20.9%), 13 cases of loosening of the prosthesis (19:4%), 9 cases of joint stiffness (13.4%), 8 cases of prosthetic dislocation (11.9%), and 3 cases of prosthesis fracture (4.5%). Pathological findings in the tissue surrounding the prostheses included debris reaction, histiocytes, acute inflammatory, chronic non-specific inflammation, pigmented villonodular synovitis (PVNS), "pseudomembranous", calcification, necrosis, sequestrum, etc. These histological changes were frequently admixed.

CONCLUSIONSVarious reasons may lead to hip and knee revision arthroplasty. The main pathological findings include infection, debris granulomas, chronic non-specific inflammatory changes, PVNS. The surgical pathology of the prosthesis provids guidances for clinical treatment and basic research.

A mutant strain RZ13 with high lipase productivity was obtained through treating the Rhizopus sp. RXF12 by UV and microwave,and its activity was 2.62-fold of the original one. The high lipase productivity of the mutant strain could be inherited after repetitious subcultures.The optimal culture conditions of the RZ13 for producing lipase were studied.The lipase with highest activity (67.32U/ml) was obtained on the conditions of 25℃,pH 8.0,5 %(v/v) single spore suspension (1?107spore/ml) and 120 r/min for 84h,and stable under 40℃ and pH 8.5. In addition,the lipase was immobilized by adsorption onto Mg-Al hydrotalcite at 25℃ for 4 h by screening carriers and optimizing the immobilization. The results showed that the optimal reaction temperature and pH were 35~55℃ and 7.5~9.0,respectively,much wider than the free lipase.

Objective To study the experience of standardized management in operation room with Da Vinci S system. Methods From January 2007 to October 2010,we set up the standardized management rules for the staff and operation appliance. Results Through the rules being carried out, the satisfaction of the doctor was increased and the hospital infection was then controlled availability. Conclusions The standardized and integrated managements are important factors for the success of surgery.

The way of "extracting-salting-chromatography" was used to purify the phycoerythrin and phycocyanin from Porphyra yezoensis in process scale-up.First,by comprehensive comparison of efficiency,the Sephadex G-25 was selected from four resins (Sephadex G-25、G-100、S-300 and CL-6B) as the best choice used in crude extract desalting of phycobiliprotein.Then the preparation process of phycobiliprotein was scaled-up with raw material(Porphyra yezoensis) increased from 1g to 20g,and finally to 400g.The results indicated that the yields of purified phycoerythrin and phycocyanin (absorption spectra purity above 3.2) increased during according to process scale-up,with 0.323% phycoerythrin and 0.148% phycocyanin obtained from 400g frozen Porphyra yezoensis blades respectively.It is no doubt that the process involved in the experiment is a potential way for large scale preparation of phycobiliproteins of high purity.

Objective: To learn the toxicity of Dendrobium officinale flowers to pregnant rats ( P, F1 ) and offspring rats ( F1, F2 ) before birth, so as to provide toxicological evidence for the safety assessment. Methods : The rats were divided into four groups with 20 female rats and 10 male each. The rats in three dose groups were fed with Dendrobium officinale flowers at the dose of 2.0, 4.0, 6.4g/kgbw. After two generation, the F1a and F2a rats were fed with basal diet; F1b and F2b rats were fed with Dendrobium officinale flowers. The body weights and total weight gains during the gestation, the conception rates, the pregnancy rates, the birth weights and survival rates of offspring rats were examined. Results: There were no statistically significant differences in the body weights and total weight gains during the gestation, the conception rates, and the pregnancy rates in pregnant rats ( P, F1 ) among the four groups ( P>0.05 ). There were also no statistically significant differences in the survival rates and live birth rates in offspring rats (F1, F2) between the dose groups and the control group ( P>0.05 ). Conclusions Dendrobium officinale flowers did not show obviously adverse effects on pregnant rats ( P, F1 ) and offspring rats ( F1, F2 ) before birth.

OBJECTIVETo analysis the early complications of tibial fracture and its related factors, and propose a solution.

METHODSFrom December 2003 to December 2013,38 patients with early complications of tibial plateau fracture after operation were retrospectively analyzed. There were 35 males and 3 females, aged from 37 to 69 years old (averaged 42.3 years). According to Schatzker classification, 3 cases were classified as type II, 2 cases as type III, 2 cases as type IV, 19 cases as type V, 12 cases as type VI. The intervals between injury and operation ranged from 9 hours to 9 days, 26 cases within 3 days. Fifteen cases were treated with internal fixation of plates and 23 were treated by plate fixation and bone transplantation. Early complications included skin necrosis in 15 cases, infection in 6 cases, osteofascial compartment syndrome in 3 cases, common peroneal nerve injury in 2 cases, the superficial peroneal nerve injury in 3 cases, popliteal artery injury in 2 cases, loss of reduction in 7 cases.

RESULTSThe wound of 14 cases healed at the first stage and 24 cases healed delay. Hospitalization days ranged from 7 to 67 days (averaged 25.6 days). All patients were followed up for 12 to 36 months with an average of 16.4 months. The fracture healing time ranged from 3 to 9 months (averaged 6.9 months). According to Merchant knee function evaluation criteria, the results were excellent in 19 cases, good in 12, fair in 5 and poor in 2.

CONCLUSIONEarly complications of tibial fracture after operation is closely associated with the severe fracture complexity and related with preoperative preparation, surgical timing, operation incision selection and surgical technique. Early detection and timely processing reduce damage.
