OBJECTIVETo compare the efficacy differences between needle-knife therapy and acupuncture-cupping for treatment of cervical spondylosis (CS) of cervical type.

METHODSSixty cases of CS were randomly divided into a needle-knife group (30 cases) and an acupuncture-cupping group (30 cases). The needle-knife therapy was applied at points among superior nuchal line of occipital bone, bilateral neck muscle, neck centerline, trapezius and medial border scapula for only once. In the acupuncture-cupping group, acupuncture was applied at Fengchi (GB 20), Fengfu (GV 16), Tianzhu (BL 10), Dazhui (GV 14), Jianjing (GB 21), Jiaji (Ex-B2, from C4 to C6), Houxi (SI 3) and Ashi point, followed by cupping on local skin, once every other day for totally six times. The score of neck stiffness and visual analogue scale (VAS) were observed before and after treatment, in follow-up of 1, 3 and 6 months after treatment in the two groups, and the efficacy was compared.

RESULTSIn the needle-knife group, 9 cases were cured, 12 cases were markedly effective, 8 cases were effective and 1 case was failed; the total effective rate was 96.7% (29/30) and the cured and markedly effective rate was 70.0% (21/30). In the acupuncture-cupping group, 8 cases were cured, 9 cases were markedly effective, 11 cases were effective and 2 cases were failed; the total effective rate was 93.3% (28/30) and the cured and markedly effective rate was 56.7% (17/30). The difference of total effective rate in the two groups was not statistically significant (P > 0.05), but the cured and markedly effective rate of needle-knife group was significantly superior to that of acupuncture-cupping group (P < 0.05). The needle-knife therapy was significantly superior to acupuncture-cupping on improvement of neck stiffness in the follow-up of 1, 3, 6 months after treatment (P < 0.05, P < 0.001); both treatments were effective on relief of neck pain, but the needle-knife group had better effects in the follow-up of 3 and 6 months after treatment compared with acupuncture-cupping group (both P < 0.01).

CONCLUSIONThe needle-knife therapy has better effects on neck stiffness and pain relief than acupuncture-cupping, and it is more treatment time saving.

Objective To investigate the regularity of thoraco-abdominal two-field lymphatic metastasis and methods of the nodal dissection in middle-third thoracic esophageal carcinoma,and to guide the scope of the lymph-node clearance.Methods Thoraco-abdominal two-field lymph-node dissection based on surgical incisions of the right chest and middle upper abdomen were conducted in 62 cases with middle-third thoracic esophageal cancer and the regularity of nodal metastasis was analyzed.Results Five hundred and five pieces of lymph node were cleaned in all 62 patients and among them 102 pieces were detected as metastasis lymph node,the nodal metastasis ratio was 20.2％ (102/505).The middle-third thoracic esophageal cancer not only includes the nodal metastases up to the trachea of the right neck,around the bilateral recurrent laryngeal nerve chains,near the esophagus and the tumor,and the lymph-node metastasis at the inferior tracheal protuberance,but also the nodal metastases down to the cardiac,around the left gastric artery and at the retina of the lesser curvature of the stomach etc,presenting a tendency of 2-way metastasis.The infiltration depth and differentiation of the tumor is of statistical significance on the nodal metastasis ratio.There was significant difference on the metastasis rate of lymph node from T1 to T4 (T1:10.0％ (1/10),T2:20.0％ (3/15),T3:43.3 ％ (13/30),T4:57.1％ (4/7),x2 =18.56,P ＜ 0.05).It indicated that metastasis rate was increased with the development of the infiltration depth.There was significant difference on the metastasis rate of high differentiation carcinoma,moderate differentiation carcinoma and low differentiation carcinoma (14.3％ (2/14) vs 39.5％ (15/38) vs 57.1％(4/7),x2 =17.75,P ＜ 0.05).Conclusion The lymph node metastasis of patients with middle-third thoracic esophageal carcinoma is significantly correlated with the depth of tumor invasion and the degree of differentiation,with the tendency of thoraco-abdominal 2-field nodal metastasis.The peritracheal lymph node at right neck and bilateral recurrent laryngeal nerve chains are important regions of the metastasis.The surgical incision of the right thorax and upper abdomen greatly facilitates the excision of the middle-third thoracic esophageal cancer and the 2-field lymph node dissection Thus on this basis,the lymph node clearance around the right trachea and at bilateral recurrent laryngeal nerve chains through the right thoracic apex is safe and feasible.

OBJECTIVE:To provide reference for improving licensed pharmacist qualification system and the legislation of Li-censed Pharmacist Law in China. METHODS:The implementation of licensed pharmacist system in China was introduced;based on the experience of licensed assistant physician system in China and pharmacy technician qualification system in USA,the necessi-ty and feasibility of setting up licensed assistant pharmacist were interpreted. RESULTS&CONCLUSIONS:At present,it is neces-sary to draw lessons from licensed assistant physician system in China and pharmacy technician qualification system in USA and set up licensed assistant pharmacist because of the shortage of licensed pharmacist,low threshold of qualification admittance,non-stan-dard licensed qualification of primary(assistant)pharmacy technician,absence of Licensed Pharmacist Law. It is recommended to promote the legislation of Licensed Pharmacist Law through clearing the definition and responsibility of licensed assistant pharma-cist,confirming examination scope and the threshold of qualification admittance,etc.

Mast cells (MCs) are bone marrow-derived and tissue-homing immune cells which have important functions.Recruitment and activation in tumors are demonstrated to be mainly mediated by tumorderived stem cell factor (SCF) and its receptor c-kit on MCs.The numbers and distributions of MCs in tumors are closely related to the growth of tumors and angiogenesis.MCs can mediate angiogenesis by releasing a series of angiogenesis factors,so as to promote the progress of tumors.

ObjectiveTo evaluate the applicable value of attitude control system combined with attitude controllable intelligent capsule endoscope for stomach examination.MethodsA total of 15 patients were recruited to the study.Manipulability of movement and posture change of capsule endoscope,diagnostic efficacy for such locations as gastric cavity,bulb and descending duodenum,image quality and patients'compliance were assessed.ResultsThe procedure was completed in 14 patients.One failed due to downfall of the endoscope to duodenum within 5 min. Mean operation time was ( 23.7 ± 6.5 ) min ( from 5 to 30 min).Ten cases of superficial gastritis,one case of superficial gastritis with bile regurgitation and 1 case of ulceration of the duodenal bulb were diagnosed.No abnormalities were found in 3 others.Endoscopic images were of high quality and only a few were influenced by gastrointestinal peristalsis.All patients showed compliance with no discomfort.Capsule endoscopes were discharged within 2 or 3 days.ConclusionAttitude control system combined with attitude controllable intelligent capsule endoscope in stomach examination is feasible and valuable in clinic.

Objective: To investigate the effects of DFMO on the growth characteristics, apoptosis and activity of telomerase of K562 cells. Methods: The growth rate, phase distribution of cell cycle and apoptosis of treated cells with DFMO were detected by cell count, morphological assay, FCM analysis and DNA electrophoresis, respectively. The telomerase activity was examined by telomeric repeat amplification protocol(TRAP). Results: In K562 cells treated with DFMO, the growth rate was markedly retarded. The increase in G1 -phase cells and decrease in s-phase population and induction of apoptosis were observed. The activity of telomerase of treated cells was inhibited. Conclusion: The growth inhibition and apoptosis induction of K562 cells treated by DFMO were associated with suppressed telomerase activity. It is suggested that inactivation of telomerase in cancer cells conld be one of important events in antitumor molecular mechanism of inhibition of polyamine biosynthesis.

Objective To explore the methods for treating no-functioning renal graft.Methods The management of 240 cases of non-functioning renal graft between 1978 and December 2003 was retrospectively analyzed.Results Twenty-nine recipients with renal failure one month after renal transplantation were subjected to removal of the renal graft. One year after renal transplantation, the recipients with renal failure received resection of the renal graft, 4 were treated with renal artery embolism, and 114 did not receive special treatment.Conclusion The non-functioning renal graft required removal at early stage of renal transplantation. At later stage, no symptomatic cases of post-transplanted renal failure required no management after stopping immunosuppressant. The appropriate management is reserved for the symptomatic cases.
