BACKGROUND:Some scholars believe that for primary spontaneous pneumothorax thoracoscopic surgery and intraoperative pleurodesis can effectively reduce the recurrence rate. <br> OBJECTIVE:To study the reliability and validity of video-assisted thoracoscopic entoiodine pleurodesis for treatment of primary spontaneous pneumothorax. <br> METHODS:Videothoracoscopy procedures were performed on 64 patients with primary spontaneous pneumothorax, including 46 males and 18 females, with an age ranging from 15 to 30 years. According to the use of pleurodesis, the patients were randomly divided into two groups:experimental group and control group. In the control group, no entoiodine was used;while in the experimental group, entoiodine dipped gauze was used on the visceral pleura. The operation time, intraoperative bleeding, postoperative drainage, postoperative leakage time, postoperative extubation time, postoperative complications and the recurrence rate of pneumothorax within 1 year after operation were compared between two groups. <br> RESULTS AND CONCLUSION:No significance was found in the operation time, intraoperative bleeding, postoperative leakage time, postoperative extubation time and postoperative complications between the two groups (P>0.05). Although the experimental group had significantly more postoperative drainage volume than the control group (P<0.05), there were no consequences of medical intervention. Video-assisted thoracoscopic entoiodine pleurodesis could significantly reduce the recurrence rate of pneumothorax in 1 year after operation (P<0.05). The results show that video-assisted thoracoscopic operation with entoiodine is a reliable and effective method to reduce the recurrence of pneumothorax after operation in patients with primary spontaneous pneumothorax.

BACKGROUND:Although thoracoscopy with pleurodesis is regarded as a positive and effective way for the treatment of malignant pleural effusion, the merit and demerit of sclerosants are directly related to postoperative recovery and the success of pleurodesis. OBJECTIVE:To evaluate the therapeutic effect of talc pleurodesisvia thoracoscopy in the treatment of refractory malignant pleural effusions METHODS:There were 14 male and 15 female patients in this study, age ranging from 38 to 79 years. Al patients with refractory malignant pleural effusion underwent talc pleurodesis under thoracoscopy. The postoperative adverse reactions, chest CT scan 1 month after operation and the fluid drainage were observed. RESULTS AND CONCLUSION:Twenty-nine patients with chest pain were observed in this study. Eighteen patients could relieve the pain itself without medications, eight patients required oral Tramadol and three patients took Demerol or morphine oraly to ease the pain. Fever occurred in three cases at 3 days after operation. Neither pneumonedema, acute respiratory failure, nor death ocurred postoperatively. One month later, complete successful pleurodesis was achieved in 24 cases, and partial successful in 3 cases, and unsuccessful in 2 cases. The results indicate that thoracoscopy with talc pleurodesis can be regarded as a positive and effective way for the treatment of malignant pleural effusion.

We enrolled 60 patients with American Association of Anesthesiologists grade Ⅰ - Ⅱ undergoing unilateral total knee arthroplasty. All patients received combined epidural and spinal anesthesia,and a nerve stimulator was used to guide placement of a femoral nerve catheter. Patients were divided into three groups according to the catheter location on X-ray : psoas muscle group ( n = 18 ), iliacus muscle group (n = 19) and local group (n =23). Visual analog scale (VAS) pain scores were recorded at rest and with movement at 4, 24 and 48 h postoperatively and sensory blockade of the femoral, obturator and lateral femoral cutaneous nerves was recorded at 24 h.There were no significant differences in femoral nerve blockade among the three groups. Obturator nerve blockade was significantly better in the psoas muscle group than in the iliacus muscle and local groups, and was also better in the local group than in the iliacus muscle group. There was no significant difference in lateral femoral cutaneous nerve blockade between the psoas muscle and iliacus muscle groups, but there was better blockade in both these groups than in the local group. At 4 h postoperatively, VAS pain scores at rest were significantly lower in the psoas muscle group than in the iliacus muscle and local groups, but there were no significant differences in VAS pain scores with movement among the three groups. At 24 and 48 h postoperatively, VAS scores at rest and with movement were significantly lower in the psoas muscle group than in the iliacus muscle and local groups.

Epidemiological surveys show that folic acid can prevent prostate cancer, but fortified folic acid may increase the risk of the malignancy. The physician data queries from the National Cancer Institute of the USA describe folate as protective against prostate cancer, whereas its synthetic analog, folic acid, is considered to increase prostate cancer risk when taken at levels easily achievable by eating fortified food or taking over-the-counter supplements. We review the current literature to examine the effects of folate and folic acid on prostate cancer, help interpret previous epidemiologic data, and provide a clarification regarding the apparently opposing roles of folate for patients with prostate cancer. A literature search was conducted in Medline to identify studies investigating the effect of nutrition and specifically folate and folic acid on prostate carcinogenesis and progression. In addition, the National Health and Nutrition Examination Survey database was analyzed for the trends in serum folate levels before and after mandatory fortification. Folate likely plays a dual role in prostate carcinogenesis. There remains some conflicting epidemiologic evidence regarding folate and prostate cancer risk. However, there is growing experimental evidence that higher circulating folate levels can contribute to prostate cancer progression. Further research is needed to clarify these complex relationships.

OBJECTIVETo study clinical results of reduction and fixation under arthroscopy for the treatment of osteochondrotical lesion in the knee.
METHODSFrom December 2012 to December 2013, 4 patients with the knee joint osteochondritis lesion and free bone fragments were treated with arthroscopy to detect the stripped cartilage, and then the cartilages were reduced with small incision and fixed by cartilage nail. There were 3 males and 1 female, with age of 15, 15, 20 and 27 years old. The durations of the disease were 1 d, 5 d, 1 month and 1 year. All the patients had swelling and effusion in the knee joint, and the floating patellar test was positive. CT examination showed bone defects and loose bodies. The Lysholm, VAS, and Tegner scale were used to evaluate the knee joint functions before and after operation.
RESULTSAll the patients underwent successful surgery. Postoperative CT showed good location of the cartilage without loss of reduced bone and cartilage. All the patients were followed up, and the duration ranged from 10 to 13 months, with a mean of 12 months. In one patient, arthroscopy examination was conducted for a second time to examine the connection of the fracture part to the surrounding cartilage, and it showed that the internal fixator was not absorbed. The Lysholm, VAS and Tegner scale of all patients were better than those before operation.
CONCLUSIONTreatment of osteochondritis lesion with the fixation of absorbable cartilage nails may reconstruct the integrity of articular surface and recover the stability of joints, and it is an effective treatment method.
