OBJECTIVETo investigate the safety and efficacy of minimally invasive achilles tendon lengthening and system rehabilitation for the treatment of contracture of achilles tendon.

METHODSFrom January 2002 to December 2010, 27 patients (31 feet) with contracture of achilles tendon were treated with minimally invasive achilles tendon lengthening and system rehabilitation. There were 11 males and 16 females with an average age of 35.5 years (ranged 3 to 65 years). Right foot was in 13 cases, left foot was in 10 cases, both feet were in 4 cases. Course of disease was from 1 to 5 years with an average of 2.3 years. The cause of contracture included postoperative complication of tibia fractures treated with intramedullary nailing in 7 feet, sequelae of lower leg compartment syndrome in 11 feet, congenital talipes equinovarus in 13 feet (both feet in 4). Before operation, all the patients walked with limping, plantar flexion anomaly was from 15 degrees to 50 degrees with an average of 35.5 degrees. The strength of quadriceps muscle of thigh was grade V in 27 feet, grade IV in 4 feet, the strength of musculus triceps surae was grade V in 24 feet, grade IV in 7 feet.

RESULTSAll the patients were followed-up for 6-24 months with an average of 11.3 months. According to standard of Arner-Lindholm to evaluate function of ankle joint, 29 feet obtained excellent results and 2 feet good. No infection, re-rupture or re-contracture was found.

CONCLUSIONMinimally invasive achilles tendon lengthening and system rehabilitation in treating contracture of achilles tendon has advantage such as simple operation, less complication, lower recurrence rate, which is favourable for thoroughly rehabilitation of patients. But, the case in which the strength of quadriceps muscle of thigh or musculus triceps surae still less than grade III after preoperative rehabilitation care should not choose the method.

OBJECTIVETo investigate the safety and efficacy of close reduction and percutaneous needle fixation for the treatment of anterior dislocation of sternoclavicular joint.

METHODSA retrospective analysis was performed with 6 cases of anterior sternoclavicular dislocation by close reduction and percutaneous needle fixation with Kirschner wire treated from January 2001 to February 2009, including 5 males and 1 female aged from 19 to 45 with an average of 28.8 years old. Among the 6 cases, 4 were on right lateral and 2 were on left lateral. The time from injured to treatment was from 6 hours to 12 days (averaged 4.5 days). The clinical effects were evaluated according to Rockwood scoring and the complications were observed.

RESULTSAll 6 patients were followed-up for 3 to 13 months (averaged 6 months). According to Rockwood scoring,the preoperative score was (7.00 +/- 0.89) points, postoperative score was (13.17 +/- 1.72) points; the results showed excellent in 5 cases and good in 1 case. No local infection, postoperative pain,recurrent dislocation,broken needle, and other complications were observed in this study.

CONCLUSIONThe treatment of anterior sternoclavicular joint dislocation with Kirschner wire minimally invasive fixation is an easy, reliable fixation with less complications.

Gastric cancer is one of the common tumors in the world and a major cause of cancer death.Although the 5-year survival rate of gastric cancer patients has increased greatly with the improvement levels of diagnosis and treatment,the high malnutri-tion rate of gastric cancer patients still has a significant impact on their overall survival and quality of life.Malnutrition is considered an independent prognostic factor for cancer patients,early detection of malnutrition in gastric cancer patients and more reasonable peri-operative nutritional support play an important role in the survival and prognosis of gastric cancer patients.This article combines exist-ing research at domestic and abroad to review the nutritional risk screening and assessment of gastric cancer patients during periopera-tive period,as well as the research progress of perioperative nutritional support and immunonutrition,in order to provide more compre-hensive nutritional management strategies for patients with gastric cancer during the perioperative period.

Objective: To investigate the expression of CD155/TIGIT in patients with osteosarcoma and its significance Methods : The expression differences of CD155 and TIGIT in tumor tissues of distant metastatic osteosarcoma patients and non⁃metastatic osteosarcoma patients were analyzed by cancer Genome Atlas ( TCGA) database.The surgically removed tissues of osteosarcoma patients were collected to prepare pathological sections and tissue chips , and the tumor tissue and cell morphology were observed by HE staining. Immunohistochemical staining was used to detect the expression of CD155 and TIGIT , and the scores were divided into high expression group and low expression group according to the scores. Chi⁃square test was used to analyze the relationship between CD155/TIG⁃IT expression and clinical features and prognosis. Results : TCGA database data showed higher expression of CD155 and TIGIT in patients with osteosarcoma accompanied by metastasis. HE staining of pathological sections revealed that tumor tissues with high expression of CD155/TIGIT contained more binuclear or multinucleated , hyperchromatic and obviously heteromorphic tumor cells. Immunohistochemical staining and score analysis of tissue chip showed that the expression of CD155 and TIGIT was correlated with clinical stage and distant metastasis ( P < 0. 05) , but not with age , sex , tumor size , pathological type and tumor necrosis rate. Conclusion CD155 and TIGIT may be one of the prognostic indicators of osteosarcoma.

Ultraviolet light(UV)-sensitive disorders refer to a group of diseases due to damages to the nucleotide excision repair mechanism which cannot effectively repair DNA damage caused by ultraviolet radiation. The inheritance pattern of such diseases, mainly including xeroderma pigmentosum, Cockayne syndrome and trichothiodystrophy, is autosomal recessive and known to involve 13 genes. As proteins encoded by such genes are involved in DNA repair and transcription pathways. There is overlap between the symptoms of such diseases, and their genotype - phenotype correlations are quite complex. To facilitate genetic and prenatal diagnosis for such diseases, a summary of the research progress is provided, which mainly focused on mutation research and genotype - phenotype correlation studies. We also propose a strategy for their genetic diagnosis based on recent findings of our group.

Objective: To explore the clinicopathological features and the renal biopsy process of a case of IgG4-related chronic interstitial nephritis with perirenal capsule involved and review associated literature to improve the clinician's understanding for this disease and to perform a better renal biopsy. Methods: The onset, diagnosis and treatment course of the disease were described and associated literature were reviewed to summary the clinicopathologic features and key points in renal biopsy. Results: The data of the patient showed that the urine specific gravity was 1.011, with urine protein ± and urine sugar 3+. The concentration of hemoglobin was 53 g/L, serum creatinine was 1665 μmol/L, and IgG4 was 9.39 g/L. Computed tomography showed that both kidneys enlarged slightly with decreased density and low density shadow around the kidneys. On contrast-enhanced scan, irregular low-density enhancement areas were found in both kidneys, and the edge of the boundary was not clear. For the first renal biopsy, no renal parenchyma was found except mainly hyaline collagen fibrils. At the second time, 3 pieces of tissues were obtained, which showed chronic interstitial glomerulonephritis. The IgG4 positive plasma cells were about 60/HPF and the IgG4⁺/IgG⁺cells ratio was more than 40%. The diagnosis of IgG4-related chronic interstitial glomerulonephritis was confirmed. After corticosteroid treatment, the serum creatinine decreased to 502 μmol/L after the patient got rid of dialysis. Conclusions There are various manifestations of renal damage caused by IgG4-related disease. It is necessary to pay attention to the involvement of the perirenal capsule, and to balance the risk of bleeding and poor sampling in renal biopsy.
