The painless needle insertion technique, summarized by Professor WU Lian-zhong during his decades of acupuncture clinical practice is introduced in this article, which is characterized as soft, flexible, fast, plucking and activating antipathogenic qi. The Sancai (three layers) lifting and thrusting manipulation technique is adopted by Professor WU for getting the qi sensation. And features of 10 kinds of needling sensation such as soreness, numbness, heaviness, distension, pain, cold, hot, radiation, jumping and contracture are summarized. Finger force, amplitude, speed and time length are also taken as the basis of reinforcing and reducing manipulations. Moreover, examples are also given to explain the needling technique on some specific points which further embodies Professor WU's unique experiences and understandings on acupuncture.

Objective: To screen the optimal formula and preparation process of vitamin B1 ( VB1 ) sustained-release tablets. Methods:The single-factor tests were used to investigate the type of filler, type and amount of matrix material hydroxypropyl methycel-lulose(HPMC), type and amount of retarder, tablet weight and core hardness. The orthogonal tests were used to investigate the amount of HPMC and ethyl cellulose( EC) and the core hardness. Results:The optimum formula was as follows:HPMC accounted for 50% of the tablet weight, EC accounted for 20%, the filler was lactose, the tablet weight was 200 mg and the tablet core hardness was 50 N. Conclusion:The prepared sustained-release tablets have significant controlled-release property, which provides reference for the devel-opment of new dosage form for VB1 .

Results The length of amplified fragment was 729 bp.The sequence of LAT gene was confirmed by Genbank.The LAT protein could be detected in the lymphocytes of asthmatic model.Conclusion The recombinant eukaryotic expression vector pCMV-HA-LAT can be successfully constructed.

Hypoxia-inducible factor(HIF) plays a key role in the adaptation of tumour cells under hypoxic circumstance,there are some advances in the literatures regarding HIF as an important target for anticancer agents and gene therapy.In this review,the molecular mechanism and clinical significance of compounds targeting on hypoxia- inducing factor was summarized.

Objective To discuss the nursing measures for patients of hepatocellular carcinoma treated with transcatheter hepatic arterial chemoembolization(TACE)and hish intensive focus ultrasound (HIFU).Methods During the period of Aug.2008-Aug.2009,TACE together with HIFU were performed in 40 patients with hepatocellular carcinoma.The perioperative nursing measures were summarized.Results During hospitalization no severe complications,such as dangerous infection,intestinal bleeding,etc.occurred in all patients.Conclusion Correct and proper periopemtive nursing care is of significant importance for the prevention of complications and for the therapeutic effectiveness.

BACKGROUND:Ankylosing spondylitis is an autoimmune disease involved in chronic systemic inflammation. Tumor necrosis factor and interleukin-6 levels increased in patients with ankylosing spondylitis. Inflammatory factors such as tumor necrosis factor and interleukin-6 can suppress CD36 expression in monocytes. OBJECTIVE: To analyze the correlation between CD36 expression in monocytes and ankylosing spondylitis. METHODS:A total of 84 newly diagnosed ankylosing spondylitis patients and 111 healthy individuals were included in this study. CD36 expressions in monocytes in ankylosing spondylitis patients and healthy individuals were tested using flow cytometer; meanwhile, biochemistry, immunology, routine blood examination and related inflammatory markers were determined between the two groups. RESULTS AND CONCLUSION:Results of baseline data in both groups demonstrated that CD36 fluorescence intensity in monocytes was significantly lower in patients with ankylosing spondylitis compared with healthy controls (P < 0.01). CD36 fluorescence intensity in monocytes was negatively correlated with C-reactive protein, erythrocyte sedimentation, interleukin-6 and tumor necrosis factor. In addition, CD36 fluorescence intensity in monocytes was negatively correlated with BASDAI score. Logistic regression analysis showed that erythrocyte sedimentation, interleukin-6, tumor necrosis factor and CD36 fluorescence intensity in monocytes were associated with ankylosing spondylitis, and risk factors for ankylosing spondylitis (P < 0.05). These findings confirm that inflammatory cytokine in patients with ankylosing spondylitis weakened the expression of CD36 in monocytes. There was a remarkable association between low expression of CD36 expression in monocytes and ankylosing spondylitis. CD36 expression of monocytes clinicaly may be considered to be an effective indicator to evaluate inflammation and disease activity in patients with ankylosing spondylitis.

Objective To discuss the value of holmium laser lithotripsy combined with choledochoscopy in the treatment of complicated common bile duct stones.Methods Under choledochoscopy,200 ?m fibre holmium laser lithotripsy of common bile duct stones was performed.The settings on the laser were 1.0 J and 10 Hz.The choledochoscope was used to access the common bile duct stones.The stones were fragmented and then extracted with irrigation or by using a basket. Results The stones were successfully removed in all the 17 cases.The duration of operation was 10~50 min(mean,20 min).Out of the 17 cases,there were 8 cases of primary closure of the common bile duct,6 cases of T-tube drainage, and 3 cases of stone removal via drainage passage.No bile duct bleeding or biliary leakage occurred after operation.Follow-up was conducted in 16 cases for 6~15 months(mean,10 months).B-ultrasonography or magnetic resonance cholangiopancreatography found no recurrent or residual stones,or bile duct stricture.Conclusions Holmium laser lithotripsy combined with choledochoscopy in the treatment of complicated common bile duct stones has advantages of minimal invasion,rapid recovery,satisfactory lithotripsy effects,simplicity of performance,and high reliability.
