BACKGROUND:Studies have shown that arthroscopic al-inside technology for meniscus repair has achieved good outcomes, and arthroscopic suture combined with sodium hyaluronate has an important role in the cartilage repair. OBJECTIVE:To observe the therapeutic effect of arthroscopic al-inside suture repair combined with sodium hyaluronate injection in the repair of discoid meniscus tears. METHODS:Twenty-two patients with discoid meniscus injury were subjected to arthroscopic al-inside suture repair combined with sodium hyaluronate injection. Al cases were confirmed to have attached edge relaxation or longitudinal crack in operation. After repair, effective rehabilitation training was done. RESULTS AND CONCLUSION:The operations for the 22 cases were al successful and there was no complication. Al patients were fol owed up for over 18 months. According to Ikenchi’s method (Lysholm knee score criterion), 11 cases were rated excel ent, 8 were rated good, and 3 were rated fair, with an excel ent/good rate of 86.36%. It is demonstrated that the al-inside suture repair under the guide of arthroscopy in discoid meniscus cases can remain the most appropriate anatomical structure of the meniscus that can play an effective function, and has the advantage of minimal invasion. Arthroscopic al-inside suture repair combined with intra-articular injection of sodium hyaluronate and standard rehabilitation training result in a lower complication rate and effectively promotes the meniscus repair.

OBJECTIVETo compare the difference in the clinical efficacy on posterior circulation ischemia between acupuncture at stellate ganglion and conventional acupuncture as well as the impacts on blood pressure.
METHODSEighty cases of posterior circulation ischemia were randomized into an observation group (40 cases) and a control group (40 cases). In the observation group, acupuncture was applied to the bilateral stellate ganglions on the neck, stimulated with reinforcing technique by rotating the needles. In the control group, the acupuncture of reducing technique was applied to Fengchi (GB 20), Baihui (GV 20), Neiguan (PC 6) and Taichong (LR 3) in the excess syndrome. The even needling or reinforcing technique was applied to Fengchi (GB 20), Baihui (GV 20), Ganshu (BL 18), Shenshu (BL 23) and Zusanli (ST 36) for the deficiency syndrome. The treatment was given once every 3 days and 4 treatments were required totally in the two groups. The changes in total syndrome score, peak Systolic blood flow velocity (Vp) of vertebral artery and basilar artery, systolic and diastolic blood pressures were compared before and after treatment in the two groups. The clinical efficacy was compared between the two groups.
RESULTSThe total syndrome score was reduced apparently after treatment compared with that before treatment in the two groups (P < 0.01), and the reducing was more obvious in the observation group as compared with that in the control group (P < 0.01). The total effective rate was 87.5% (35/40) in the observation group, higher than 67.5% (27/40, P < 0.05) in the control group. After treatment, the reduced Vp of vertebral artery was not improved apparently as compared with that before treatment in the control group, Vp in blood velocity abnormality (including vascular spasm, stenosis or reduced velocity) of vertebral artery and basilar artery was all improved as compared with that before treatment in the two groups (P < 0.01), and the improvements in the observation group were more obvious than those in the control group (P < 0.01). After treatment, the systolic and diastolic pressures were reduced as compared with those before treatment in the two groups, and the reduced systolic and diastolic pressures in the observation group were more apparent than those in the control group (P < 0.01).
CONCLUSIONAcupuncture at stellate ganglion achieves the satisfactory efficacy in the treatment of posterior circulation ischemia and the significant efficacy of reducing blood pressure, more advanced than the conventional acupuncture.

Objective To investigate the treatment effect of proximal femoral nail antirotation (PFNA) on unstable femoral intertrochanterie fractures in the elderly. Methods A retrospective stud- y was done on 65 patients with unstable femoral intertrochanteric fractures, who were treated with PFNA from December 2005 to October 2006 and followed up for at least half a year. There were 22 males and 43 females, at age range of 67-97 (mean 78.5 years). All the operations were carried out within a week af- ter fractures. The data of operation time, operative blood loss, complications, bone healing time and hip function scores were recorded for evaluating treatment outcomes. Results All the patients were fol- lowed up for 6-18 months (average 10.5 months). The operation lasted for (29.6±7.5) minutes, with mean blood loss of (150.5±40.2) ml and bone healing time of (9.1±2.2) weeks. All patients ob- tained satisfactory treatment results, except for 3 patients with proximal thigh pain, 2 with pulmonary in- fection occurred and 1 with thrombs of lower limb vein. Harris post trauma hip function score was (88.5 ± 6.3) points. Conclusion PFNA is an effective way for femoral unstable intertrochanteric fractures in the elderly, for it is characterized by short operation time, less blood loss and stable fixation.

Objective To identify the protein interacting with hepatitis E virus(HEV) recombi-nant capsomeric particles(P239). Methods Protein interacting with HEV was analyzed by the pull-down, MALDI-TOF-MS, co-immunoprecipitation (Co-IP) and CONFOCAL. Results A protein interacting with HEV recombinant particle (P239) was identified as HSP90 by MALDI-TOF-MS. The interaction between HSP90 and P239 was further confirmed by Co-IP. The protein level and localization of HSP90 and P239 in HepG2 were detected. The total quantity of HSP90 didn't change, and the movement of HSP90 from plasma membrane to perinuclei region with P239 was observed. Conclusion HSP90 may play an important role in the trafficking of P239. It suggests that HSP90 participate in the transportation of HEV after infection, which may contribute to the prevention and control of the disease.

Objective To search for the neutralizing epitopos on hepatitis E virus (HEV) capsid besides the known neutralizing epitope (aa459-606). Methods By analysis of several strains of monoclonal antibodies against HEV capsid and their recognized epitopes, the neutralizing activity of epitope (aa394-458) at N-terminus was compared with that of an immunodominant neutralizing epitope (an459-606). Re-suits The research showed a novel potential neutralizing epitope in aa423-437 of HEV ORF2 though detec-ting and comparing the characteristics of several antibodies and corresponding determinations. The epitope is a linear non-immunodominant epitope which is different from the other neutralizing epitope in aa459-606.And the amino acids sequence of this novel epitope is conservative. Conclusion ORF2 aa423-437 is a no-vel potential neutralizing leaner epitope of HEV. It is believed that the present work adds fundamental knowl-edge to our understanding of HEV capsid domain and contributes to the prevention and control of this dis-ease.
