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.

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.

BACKGROUND: According to up-to-date development, the best timing to repair cleft palateis at 9-12 months old after birth when the articulation does not begin to develop.However, there are many over-eight-year-old children who still suffer from unrepaired cleft palate. Therefore, it is veryimportant to adopt proper surgery for these patients to improve palate form and articulatory function. OBJECTIVE: To study the characteristics of the cleft palate in patients of over 8 years old and the effects of palate repair and posterior pharyngeal flap transplantation (PPFT) on articulation. DESIGN:A controlled study with children patients as subjects. SETTING: Department of Maxillofacial Surgery, Medical College of Stomatology, Fourth Military Medical University of Chinese PLA PARTICIPANTS: Twenty-four children patients of cleft palate who were treated in the Department of Maxillofacial Surgery ,Medical College of Stomatology, Fourth Military Medical University of Chinese PLA from January 2000 through December 2003 were enrolled in the study. Fourteen were male and ten female. Their ages varied from 8 to 20 years old (mean 13.8 years). Three cases were bilateral complete cleft palate and twelve cases were unilateral complete cleft palate. Nine were incomplete cleft palate. METHODS :Two flap palatoplasty and upper pedicle PPFT were conducted in all the patients. In thirty days after surgical treatment, the patients were asked to repeat the words of a doctor in the phonetic lab with his or her lips 10 cm away from microphone. The words of the patients were recorded and evaluated subjectively by 5 doctors specialized in pathologic phones. MAIN OUTCOME MEASURES :The palatopharynx was observed with nasopharyngoscope before and after operation. And the improvement of nasal gas leakage and enhanced rhinophonia were also evaluated. RESULTS: The repaired cleft palate was healed in the first intention in all the patients. The soft palate retreated satisfactorily and the palatopharynx was apparently closed, which created good preconditions for articulation. The patients' articulation was also improved in different degrees. All the 24 patients had the fourth grade of enhanced rhinophonia and nasal gas leakage before repairing. After palate repair and PPFT, the enhanced rhinophonia and nasal gas leakage of grade 1 was in 3 patients, grade 2 in seven, grade 3 in six and grade 4 in eight patients. CONCLUSION: The combination of palate repair and pharyngoplasty is able to improve the form of soft palate and the articulation of over-eightyear-old patients with cleft palate.

ObjectiveTo explore the practicability of combined surgical treatment for the patients with Hepatocellular Carcinoma(HCC) complicated with Portal Hypertension(PH).MethodsThe clinical data of 43 patients withHCCcomplicatedwithsignificantesophagealvaricesandhyperspleniawereanalyzed retrospectively.All patients were diagnosed with esophageal varices and hypersplenia of different degrees, 14 of them had severe esophageal varices, the other 29 patients had moderate esophageal varices.Firstly all patients underwent splenectomy, 18 of them had selective portoazygous devascularization in addition.After that the patients received hepatectomys ,with local excision or segmentectomy as the major operation methods.Results All patients received hepatectomy combined with splenectomy treatment.There was no perioperative mortality, but 12 patients had complications after the surgery.Over seventy percents patients(33/43)accepted regular followup.Among these 33 patients,the 1-year and 3-year survival rates were 90.9％ (30/33) and 63.6％ (21/33)respectively.Eleven patients died of tumor recurrence.Four patients had upper postoperatively gastrointestinal hemorrhage.ConclusionHepatectomy combined with splenectomy didn't increase the mortality in the patients with HCC complicated with PH.The combined surgery might reduce the incidence of severe complications, such as postoperative bleeding.We believe the combined surgical treatment is feasible for this group of the patients.

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.

ObjectiveTo explore the clinical effect of video-assisted thoracoscopic surgery(VATS) for chronic empyema. Methods74 patients with chronic empyema were divided into experimental group and control group,control group was given decorticationoflung,and experimental group was given VATS. ResultsThe duration of chest tube drainage, hospitalization and complications in experimental group was significantly better than that in control group,it showed better clinical effect. ConclusionFor part of patients without the serious disease change of chronic empyema, if the surgery indication could be controlled strictly, the VATS was considerable.

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.
