Sheng's acupuncture manipulation at bone-nearby acupoints is a set of needling manipulation of the chief physician of TCM, SHENG Xie-sun, summarized through his over 50 years clinical experiences and on the basis of Internal Classic. Regarding this manipulation, on the premise of acupoint selection based on syndrome differentiation, the acupoints close to bone are possibly selected and punctured, with the needle tip toward bone edge, and followed by the technique to achieve reducing purpose. Clinically, the significant immediate analgesia can be achieved in pain disorders such as headache and toothache. Professor Sheng thought, corresponding to the location of needle insertion and needling depth, the tissue layers of needle tip passing through should be considered specially. The site of needle insertion should be changeable so as to ensure the needle tip reaching the bone. This manipulation for analgesia provides a certain guide for acupuncture study, especially for the mechanism study on acupuncture analgesia.

AIM:To observe autophagic apoptosis induced by docetaxel in cervical cancer HeLa cells in vitro,and explore its potential molecular mechanism. METHODS:Cervical cancer HeLa cells in vitro were treated with docetaxel of different concentrations (1,5,10,20,40 ?g/mL) and different time (6,12,24,48,72 h). The growth inhibiting of HeLa cells was observed by methyl thiazolyl tetrazolium(MTT) assay. Inverted microscope and electron microscopy were used to observe cell morphological changes. The apoptosis ratio and cell cycle were determined by flow cytometry(FCM). The expression of autophagy gene Beclin 1 was examined by reverse transcriptase polymerase chain reaction(RT-PCR) technique. RESULTS:Docetaxel inhibited the proliferation of cervical cancer HeLa cells in a dose-dependent and time-dependent manner(P

Objective To explore a surgical therapy on close depressed fracture of the skull.Methods Ni-Ti form memory-alloy cramps were fixed on between the depressed bone and the normal surrounding skull in 16 patients with close depressed fracture of the skull.Results The follow up was 5～54 months(average 26 months).It indicated that there was no displacement and depressing of the fixed bone, no subcutaneous collection of fluid, no reject reaction and inflammation, and no erosion. The fixed bone and skull density showed normal by X ray and the fixed cramp did not disturb CT and MR scaning. All patients declared no mental burden and felt safe.Conclusion The Ni-Ti form memory-alloy cramp has a good mechanical restoration force and a good plastic effect,but no complication,it can increase the ability to resist external force in fracture region, and the surgical procedure is very simple, therefore it is ideal to treat the depressed fracture of skull.

Objective To discuss the opportunity of hemilateral craniotomy in treatment of a large area combined middle cerebral artery (MCA) infarction.Methods Thirty-two patients with a large area combined MCA infarction were performed by hemilateral craniotomy.Initial clinical presentation was evaluated by the Glasgow coma scale(GCS).All survivors were assessed three months after surgical decompression according to Barthel index(BI).The effects of pre-hemia decompressive surgery(before any signs of cerebral hernia,based on clinical status and CT or DWI findings)versus post-hernia surgery (after signs of hernia) on mortality,functional outcome.Results In 18 patients with pre-hernia decompressive surgery,3 patients (16.7%)were dead and average BI was (66.94±7.75)scores.The mortality was 57.1%(8/14)and average BI was (38.43±9.82)scores of post-hernia surgery with 3 cases severe aphasia.Conclusion Hemilateral craniotamy is performed before occurrence of cerebral hernia may decrease the mortality and improve outcome in these patients.

Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a member of the TNF super family found in recent years, which widely exists in the body tissues and participates in the immune regulation, immune stability, and immune surveillance of the human body. The TRAIL receptor is expressed in the surface of a variety of cells. Recent studies show that TRAIL induces the apoptosis of tumor cells and has no significant toxic effect on normal cells. Its anti-tumor activity and safety have been widely recognized. The development of prostate cancer is regulated by the mechanisms of cell apoptosis. TRAIL can induce the apoptosis of prostate cancer cells, and therefore has a great application value in the treatment of prostate cancer.
