OBJECTIVETo investigate clinical effects of arthroscopy in the treatment of medial meniscal cyst.

METHODSFrom June 2011 to January 2013, 7 patients with medial meniscal cyst were treated with arthroscopy. There were 3 males and 4 females,ranging in age from 27 to 63 years old,with a mean age of (43.93±2.10) years old. The cysts have been discovered for 3 to 30 months,with a mean time of (10.6±1.3) months. All the patients complained of knee pain,especially in the medial joint gap. The Pisani sign, Caklin sign and medial McMurray sign were all positive. Preoperative MRI examination confirmed the diagnosis. Lysholm score changes and clinical efficacy were observed through a six-month follow-up.

RESULTSThe postoperative Lysholm scores were all significantly higher than the preoperative scores. According to Sarimo standard, 6 patients got an excellent result, and 1 good.

CONCLUSIONArthroscopic treatment of medial meniscal cyst has replaced the traditional method, which could retain the normal meniscus as much as possible and repair the meniscus injury simultaneously, as well as get a good curative effect and a good recovery of knee function. This method is worthy of clinical application.

Objective To summarize and discuss the diagnostic and treating experiences of chronic pancreatitis with mass in the head. Methods Eight patients of chronic pancreatitis with mass in the head who were misdiagnosised as carcinoma of head of pancreas were analyzed retrospectively in the past 10 years. Results All the patients exhibited abdominal pain,5 of whom were with jaundice and 3 with anorexia. All the patients were misdiagnosised as carcinoma of head of pancreas before the operation,but the pathology after operation indicated chronic pancreatitis. The pancreaticoduodenectomy was performed in 5 patients,the choledochojejunostomy in 2 patients,while the exploratory laparotomy in 1 patient. After the operations,the abdominal pain was relieved in 7 patients, while 2 patients who accepted pancreatoduodenectomy suffered from pancreatic fistula,1 of whom died in the end. Conclusion It’s hard to differentiate the chronic pancreatitis with mass in the head from the carcinoma of head of pancreas before operation. If the carcinoma of head of pancreas can’t be excluded during the operation,the pancreatoduodenectomy should be performed,while the duodenum-preserving total resection of the head of the pancreas or any intra-drainage operations should be done if chronic inflammation is found in the whole pancreas with a negative result of the biopsy of the pancreas through the needle aspiration.

Objective To compare three kinds of irradiation treatment plans for cervical and upper thoracic esophageal cancer,in order to arrived at proper decision for the patient.Methods From February 2001 to June 2004,43 such patients were studied with three different simulated treatment plans made including conformal plan,conventional four-field plan and conventional two-field plan for every one.All plans were evaluated with iso- dose curve and dose-volume histogram.Results GTV on 95% isodose curve was 99.5%,98.2% and 87.4% in conforaml plan,conventional four-field plan and conventional two-field plan,respectively;PTV_1 and PTV_2 on 95% isodose with 97.8%,97.2%,94.8% and 95.8%,86.6%,73.7%.The volume of＞20 Gy dose of left lung accepted was 18.6%,17.2% and 32.3%,in conformal plan,conventional four-field plan and conventional two-field plan,respectively;the right lung received 20.5%,19.9% and 35.5%.Conclusions Conformal plan is the best in radiotherapy,as it can provide ideal dose distribution of irradiated target with adequate protection of the normal tissues.Conventional four-field plan,being easy to carry out,can replace the conformal plan in most situations.Conventional two-field has the most uneven dose distribution and largest lung volume irradiated.

Objective To research the infections of respiratory syneytial virus(RSV)in children with respiratory tract inflammation and define its molecular epidemic features in Urumchi.Methods SamDles were collected from November 2006 to April 2007 in the People's General Hospital of Xinjiang Uygur Autonomous Region,including 112 respiratory secretions and 280 nasopharyngeal swabs. RSV and its subgroups were detected by nested PCR.The five positive amplicons selected randomly from all positive samples were sequenced and compared with other RSV in GenBank by BLAST and DNAStar.Results of all 392specimens.68 RSV G gene segments were tested.Among them,RSV lineage A occupied 93.3%,while B occuDied 6.7%.The identities between them were 63.1%-99.4%.Phylogenetic analysis defined that they belonged to two different clusters.Conclusion RSV was one of the important viruses leading to children's respiratory tract infections in the People's General Hospital of Xinjiang Uygur Autonomous Region during winter and spring from 2006 to 2007.RSV subtype A was the prevalent genotype in the hospital dunng this epidemics.

Objective: To investigate the potential role of me latonin in the adrenal cortex of human embryo. Methods:Specifi c melatonin receptors was localized and characterized in the adrenal cortex of h u man embryo by means of immunohistochemistry. Results: mt1 （Me l1a）and MT2 （Mel1b）subtype of melatonin receptors was principally localize d to cytoplasm in zona glomerulosa， fasciculata and reticularis. Conclu sion: It is possible that mt1 and MT2 subtype of melatonin receptors co-exist in the adrenal cortex of human embryo.

OBJECTIVETo investigate the potential protective effect of the mitochondria-targeted antioxidant Mitoquinone (MitoQ) on post-thaw human sperm.

METHODSSemen samples were collected from 60 normal fertile men, each divided into six parts of equal volume to be incubated at 37 °C in normal saline (G0, control) or in the extender with 2 nmol/L (G1), 20 nmol/L (G2), 200 nmol/L (G3), 2 µmol/L (G4), and 20 µmol/L of MitoQ (G5). After one hour of incubation, the samples were subjected to computer-assisted semen analysis (CASA) for sperm motility, flow cytometry for reactive oxygen species (ROS), thiobarbituric acid assay for the concentration of malondialdehyde (MDA), and MitoTracker fluorescent staining and flow cytometry for the sperm mitochondrial membrane potential (MMP). Then, the semen were cryopreserved with none (B0), 200 nmol/L (B1), and 2 µmol/L of MitoQ (B2), followed by detection of the changes in the ROS, MDA, and MMP of the post-thaw sperm.

RESULTSThe percentage of progressively motile sperm and total rate of sperm motility were significantly higher in G3 ([30.8 ± 10.2]% and [70.6 ± 9.0]%) and G4 ([32.7 ± 13.5]% and [70.3 ± 11.9]%) than in G0 ([17.6 ± 5.0]% and [54.9 ± 11.5]%) (P < 0.05). The level of ROS dropped markedly with the increased concentration of MitoQ, 86.5 ± 31.6 in G3, 93.6 ± 42.0 in G4, and 45.1 ± 15.0 in G5, as compared with 160.8 ± 39.7 in G0 (P < 0.05). The content of MDA was remarkably lower in G3 ([0.9 ± 0.5] µmol/mg) and G4 ([0.9 ± 0.5] µmol/mg) than in G0 ([1.9 ± 1.1] µmol/mg) (P < 0.05), but not in G5 ([1.7 ± 0.7] µmol/mg), which was even higher than in G3 and G4 (P < 0.05). The MMP showed a significant reduction in G5 (1156 ± 216) in comparison with G0 (1701 ± 251) (P < 0.05) but exhibited no remarkable difference between G0 and G1 (1810 ± 298), G2 (1995 ± 437), G3 (1950 ± 334), or G4 (1582 ± 314). The percentage of progressively motile sperm and total rate of sperm motility after freezing-thawing were significantly decreased as compared with those of the fresh semen (P < 0.01), but both were remarkably higher in B1 ([3.2 ± 2.3]% and [ 43.0 ± 9.5]%) than in B0 ([0.8 ± 0.6]% and [26.5 ± 11.4]%) (P < 0.05). The ROS level was significantly lower in B1 and B2 than in B0 (34.6 ± 12. 3 and 37.0 ± 10.5 vs 56.9 ± 14.3, P < 0.05), and so was the MDA content ([1.4 ± 0.5] and [1.4 ± 0.6] µmol/mg vs [2.6 ± 1.0] µmol/mg, P < 0.05), but the MMP was markedly higher in B1 and B2 than in B0 (1010.0 ± 130.5 and 880.6 ± 128.6 vs 721.1 ± 24.8, P < 0.05).

CONCLUSIONAddition of MitoQ to the freezing extender at 200 nmol/L may effectively improve the quality of human sperm and MitoQ is a good protective addictive for human sperm cryopreservation.
