Objective To study the relationship between serum insulin-like growth factor-1(IGF-Ⅰ) levels and prostatic cancer. Methods The levels of IGF-Ⅰwas measured with immunoradiometric assay(IRMA) in 37 cases of prostatic cancer,35 cases of benign prostatic hyperplasia (BPH) and in 20 healthy subjects as controls.The serum IGF-I levels were compared to the clinical and pathological grading of the prostatic cancer.8 cases of prostatic cancer after operation have been followed up. Results The mean levels of serum IGF-I in prostatic cancer (325.6?100.8 ng/ml) were significantly higher than those in BPH (201.6?53.8 ng/ml) and healthy subjects (179.0?57.2 ng/ml) (P0.05).Statistical difference was noted before ( 315.8?87.0 ng/ml) and after (224.8? 88.4 ng/ml) PCa operation(P0.05). Conclusions The levels of serum IGF-I may be a new marker to prognose and for early diagnosis of PCa in high risk population.

BACKGROUND: Early clinical researches suggest that mediodespidine capsule can decrease blood pressure of patients with primary hypertension on the basis of yanggan qinggan pinggan technique.OBJECTIVE: To observe the effect of mediodespidine capsule on primary hypertension and angiotensin Ⅱ (Ang- Ⅱ ) of patients in the types of yin deficiency, yang excess and liver fire.DESIGN: Randomized controlled case observation.SETTING: Department of Cardiology, First Affiliated Hospital, Hunan University of Traditional Chinese Medicine.PARTICIPANTS: Patients were selected from the Inpatient Department and Out-patients Clinic of the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine between April 1999 and April 2000. Inclusion criteria: Patients, who were diagnosed with the criteria of primary hypertension, who belonged to the types of yin deficiency, yang excess and liver fire, who could endure this test, who were coincidence with the criteria of mental-stress test, were all consent. Exclusion criteria: Patients who had severe congestive heart failure, atrophic arthritis and unable tolerance were excluded. There were 60 cases in total, including 29 males and 31females. All patients were divided into mediodespidine group and verapamil group with 30 in each group on the basis of randomly digital table.METHODS: Patients who had positive results of awaken mental-stress test were involved in this study. Cases in mediodespidine group were treated with mediodespidine capsule, which was made of tall gastrodia tuber, spine date seed and fourstamen stephania root at the dosage of 0.43 g/pill and were provided by the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine (wei yao ji zi: 05-047, batch number: 990503), five pills each for 3 times a day. Cases in verapamil group were treatedwith verapamil (40 mg/pill, Shanghai Huanghe Liya PharmaceuticalCompany Limited,batch number: 980301B) 80 mg each for 3 times a day. The course in both groups was 4 weeks. ① Effect of blood pressure: Average value of blood pressure tested for 3 successive days were regarded as the blood pressure before treatment, and average value of blood pressure tested for 3 times after treatment was regarded as the blood pressure after treatment. ② Effect of symptom:Scores were recorded as four levels according to main symptoms, such as vertigo, headache, pain and weakness of waist and knees, before and after treatment. ③ Values of Ang- Ⅱ were measured with radioimmunoassay before and after cold pressor test. Effect on Ang- Ⅱ was evaluated with effect of decompression, effect of clinical symptom and criteria of clinical effect.MAIN OUTCOME MEARUSES: Clinical symptoms, values of blood pressure, heart rate and Ang- Ⅱ before and after cold pressor test.RESULTS: A total of 60 patients with primary hypertension were involved into the final analysis.① Totally effective rate of clinical symptoms of patients in mediodespidine group was higher than that of patients in verapamil group, but the effect of decompression was not significant between the two groups (P ＞ 0.05). ② There was remarkably significant difference of heart rate in both groups before and after treatment (P ＜ 0.01), especially the decrease in verapamil group was great, and there was significant difference (P ＜ 0.05). ③ Values of systolic pressure and diastolic pressure were decreased in both groups after cold pressor test (P ＜ 0.01), but there was no significant difference between the two groups (P ＞ 0.05). ④ There was no significant difference in clinical effect between the twogroups (P ＞ 0.05).⑤ After treatment, concentration of Ang- Ⅱ at basic level in both groups was decreased, and there was significant difference between them (P ＜ 0.01);concentration of Aug-Ⅱ was decreased in both groups after cold pressor test as compared with that before treatment, but there was no significant difference between them (P ＞ 0.05).CONCLUSION: Mediodespidine capsule can decrease blood pressure stably, and the effect is stronger than that of verapamil at the aspect of decompression and improving symptoms. Blood pressure of patients with primary hypertension in the types of yin deficiency and yang excess or liver fire can be decreased by decreasing the level of plasma Ang-Ⅱ to a certain degree.

Objective To observe the influence of early involvement of rehabilitation treadmill on hip function and daily life after total hip arthroplasty (THA).Methods Totally 80 patients receiving THA in Foshan Hospital of Traditional Chinese Medicine from January 2013 to January 2016 were randomized into a trial group (40 cases) and a control group (40 cases).The control group underwent conventional rehabilitation treatment such as training of muscle strength,joint motion and daily life,and the trial group applied rehabilitation treadmill for early training besides above measures.The two groups were compared on Harris score,Barthel scaore and re-visiting rate at the time points of 1,3 and 6 months after THA.Results Follow-up was carried out for the two groups.Harris scores and Barthel scores of the two groups were significantly enhanced 3 and 6 months after THA (P＜0.05).Harris scores in the trial group were (83.08±2.38) and (88.05±2.54) respectively 3 and 6 months after THA,which were statistically higher than (69.03±2.39) and (74.85±3.39) of the control group.Barthel scores in the trial group were (79.25±3.31) and (90.25+2.25) respectively 3 and 6 months after THA,which were obviously higher than (75.13±3.10) and (84.88±3.84) in the control group.The trial group had the re-visiting rate (17.5％) significantly higher than that (37.5％) in the control group 6 months after THA (P＜0.05).Conclusion Early involvement of rehabilitation treadmill combined with conventional training promotes the recovery of hip function,lower limb muscle strength,walking ability and daily life,while decreases the re-visiting rate of the patient.

Objective To evaluate the result of staged arteriovenous shunts for the treatment of thromboangiitis obliterans(TAO) and arterial sclerosis obstruction (ASO). MethodsData of 176 cases undergoing this procedure were retrospectively reviewed. ResultsIn this group, 147 cases (83 5%) were followed up with a median of 9 8 years. Pain and/or claudication disappeared in 86 out of 90 cases (95 5%) treated by low positioned shunt one week postoperatively, with a limb salvage rate of 100%. Among 57 cases treated by high positioned shunts of the lower limbs, pain and claudication disappeared in 43 cases (75 4%) 2~3 weeks postoperatively. Postoperative amputation has to be performed in 5 cases with a limb salvation rate of 91%. ConclusionsThe clinical result of this staged arteriovenous shunts is satisfactory for the treatment of thromboangiitis obliterans(TAO) and arterial sclerosis obstruction (ASO).

This study described the radiological features on echocardiography and MRI specific to cardiac amyloidosis confirmed on biopsy. Eleven cases of biopsy-proven cardiac amyloidosis were retrospectively reviewed in this study. All patients underwent biopsy, cardiac MRI and echocardiography. The main echocardiography and MRI findings were as follows: diffuse ventricular and septum wall thickening, atrial enlargement, pericardial effusion, restricted left ventricular (LV) systolic and diastolic function, characteristic granular sparkling of myocardium. MRI revealed a characteristic pattern of global subendocardial late enhancement, extending in varying degrees into the neighboring myocardium. The findings agreed with the infiltration distribution of amyloid protein. Typical abnormalities seen on echocardiography and MRI should have important diagnostic and prognostic value of cardiac amyloidosis. MRI should be considered in the diagnosis of cardiac amyloidosis if echocardiographic features are suspicious.

In order to compensate for the deficiencies of current medical education, improve the comprehensive quality of medical students, the First Clinical College, Tongji Medical College of Huazhong University of Science and Technology took the lead in carrying out the health management practice of rela-tives and friends, and made a beneficial exploration of humanistic education for medical students. Relatives and friends were regarded as the specific practice objects, and by telephone and network at school, face-to-face communication during the vacation, medical students established, managed and track the health records of relatives and friends. The students could practice while learning, which made medical students, in im-proving the knowledge structure, enhance their emotional communication with friends and relatives, improve their doctor-patient communication ability, establish the concept of humanistic care, and cultivate their occupation moral respect for life and their dedication to medicine and the sense of responsibility and mission to the society. It provides a new strategy for medical humanities education.

Objective: The purpose of this study was to evaluate the safety and effectiveness of fast track surgery in laparoscopic gastrectomy for gastric cancer. Methods: All patients received elective gastric cancer resection, and were divided into three groups: group Ⅰ (open gastrecomy, n = 30) , group Ⅱ (open gastrecomy with fast track surgery, n = 30) , and group Ⅲ (laparoscopic gastrecomy with fast track surger-y ,n =30) . Clinical data and gut function were assessed in three groups. Results: There were no significant differences in postoperative complication and the number of lymph node harvest between 3 groups. Blood loss was less in group Ⅲ than group Ⅰ and group Ⅱ (P <0.01) ,but its operative time was longer and its cost was more than other two open surgery groups (P < 0. 01). Recovery of bowel function in group Ⅲ was faster,and postoperative hospital stay was shorter than group Ⅰ (P<0.01). However, recovery of bowel function and postoperative hospital stay in group Ⅲ was not different from group Ⅱ (P > 0. 05). Conclusion: Postoperative hospital stay can be shorter and recovery of bowel function can be faster in laparoscopic gastrectomy with fast track surgery plan compared to traditional care group. But when using fast track surgery plan, laparoscopic gastrectomy was not superior to open surgery.

Objective: We present our preliminary experience of using a homemade transumbilical single-port access for performing transumbilical single port access (SPA) laparoscopic surgery for gastrointestinal disease and its perioperative nutritional management.Methods: During Nov.2009-Dec.2009,five patients received SPA surgery and nutritional management following the protocol of fast track surgery.A patient with stomach GIST received partial gastrectomy,a patient with ascending colon lymphoma received right hemicolectomy,a patient with rectal cancer received anterior resection,a patient with jejunum GIST received partial small bowel resection,and a patient with early gastric cancer received distal subtotal gastrectomy (D1+α). Results: Transumbilical SPA surgery were successfully done in five patients without conversion.The mean length of incision was 3 cm,the mean time for operation was 138 (60-240)min,and the mean blood loss was 50 (10-100)ml.All patients could mobilize and orally drink on the 1st day after operation,have soft diet the 3st days after operation,their mean postoperative hospital stay was 4 days.No complication occurred.Mean body weight loss was 2.6 kg on discharge compared with at admission.Conclusion: Transumbilical SPA surgery with the protocol of fast-track surgery had advantages including shorter incision,less trauma,faster recovery,and less body weight loss.
