Objective] To study the effect of kneading pull-turning methods together with the family care and treatment on children congenital muscular torticollis. [Methods] 60 cases of congenital muscular torticollis were randomly divided into kneading pull-turning methods together with the family care group(treatment group) and conventional massage group(control group) with symptoms, signs and evaluation of clinical curative effect between groups of children. [Results] The treatment group cure rate was 76.67%, control group cure rate was 43.33%, the curative effect of treatment group was obviously better than the control group(P<0.05). [Conclusion] Kneading pull-turning methods together with the family care in treatment of children with congenital muscular torticollis has the characteristics of high cure rate which is conducive to recovery of affected children.

0.05). But when the flexion exceeded 30?, especially when it exceeded 60?, the displacement in pPc increased markedly, much greater than that of an intact knee (P0.05), while a slight over-restriction may be found at some angles. Conclusion Double-band reconstruction could effectively restrict the posterior displacement of the tibia and restore anteroposterior stability to the knee joint within its full range of flexion. aPc reconstruction could also maintain the posterior stability of the knee, while the result of pPc reconstruction is most unsatisfactory.

BACKGROUND:Celastrol is one of the active components extracted from the traditional Chinese medicine Celastrus orbiculatus characterized by expel ing the wind and promoting blood circulation and relieving swel ing and pain.
OBJECTIVE:To investigate the effects of celastrol on tumor necrosis factor-α(TNF-α) induced proliferation and inflammatory responses in RAW264.7 cel s.
METHODS:In vitro inflammatory cel models induced by TNF-α(0, 1, 10, 100μg/L) were treated with celastrol (0.1, 0.5, 1.0, 2.0μmol/L). Interleukin-1β,-6,-8 and prostaglandin E2 in the models were measured by enzyme-linked immunosorbent assay. Cel survival was determined by cel counting kit-8. The inflammatory mediator nitric oxide secretion was detected by nitrate reductase assay. mRNA expressions of inducible nitric oxide synthase, cyclin D1 and cyclin E1 were detected by real-time polymerase chain reaction technique.
RESULTS AND CONCLUSION:Significantly increased secretion of interleukin-1β,-6,-8, prostaglandin E2 and nitric oxide, cel proliferation, and mRNA expressions of inducible nitric oxide synthase, cyclin D1 and cyclin E1 were observed after the induction of TNF-α(0.1, 10, 100μg/L) compared with the control group (without the induction of TNF-α) (P<0.05);especial y, 10μg/L of TNF-αexhibited the strongest effects. 0.4μmol/L celastrol significantly suppressed TNF-α-induced release of interleukin-1β,-6,-8, prostaglandin E2 and nitric oxide, cel proliferation, and mRNA expressions of inducible nitric oxide synthase, cyclin D1 and cyclin E1 in RAW264.7 cel s (P<0. 05). Our results demonstrate that celastrol can inhibit TNF-α-induced inflammatory response and proliferation in RAW264.7 cel s.

Objective To compare the clinical effects of mini phalangeal external fixation and mini plate in the treatment of intraarticular fractures of the metacarpal bone head,and to provide a theoretical basis for clinical selection of surgical plan. Methods Seventy?four cases of metacarpal bone head intraarticular fractures treated in Huizhou People′s Central Hospital from March 2014 to March 2016 were selected as the research object. All cases were closed fractures and were randomly divided into the external fixation group and the mini plate group,37 cases in each group and treated respectively with the mini phalangeal external fixator and mini AO plate. The patients were followed up for 6 months to 1 year,the function of the metacarpophalangeal joint,the union of the fracture and the incidence of side effects were compared between the two groups. Results The excellent rates of the external fixation group at 6 months and I year after operation were 91. 9% ( 34/37) and 97. 3%( 36/37) respectively,which were significantly higher than those of the mini plate group ( 73. 0%( 27/37) ,81. 2%( 30/37 ) ) , the difference was statistically significant (χ2 = 7. 120, 7. 062, P<0. 05 ) . The complication rate of the external fixation group was 2. 7%( 1/37) ,which was significantly lower than that of the mini plate group ( 24. 3% ( 9/37 ) ) , the difference was statistically significant ( P=0. 014 ) . The average fracture healing time in the external fixator group was (2. 6±0. 4) months,which was significantly lower than that in the mini plate group (3. 1±0. 7) months,the difference was statistically significant (t=2. 40,P<0. 001) . Conclusion In the treatment of metacarpal bone head fracture,the external fixation has small trauma,can do cross joint fixation,and maintain a good fixation strength,and promote the healing of fracture and the recovery of metacarpophalangeal joint function. It is worthy of clinical application.

HLA-G belongs to non-classical HLA-class Ⅰ genes.It is expressed in the fetal-maternal interface on the extravillous cytotrophoblast and in such immune privilege tissues as the cornea and pancreas.However, under pathological conditions, such as tumor, inflammatory diseases and post transplantation, HLA-G is expressed abnormally.HLA-G can interact with its acceptors or immune cells and suppress the function of immune cells, which facilitates the escape of the surveillance of the human immune system and the consequent damage.In clinical studies,HLA-G is related to some clinical parameters.This review will focus on the expression, function and regulatory mechanisms of HLA-G in cancer immunology.

BACKGROUND: Studies have shown that hemiarthroplasty is suitable for single femoral head diseases with normal acetabulum. But indications for choosing bone cement or biological fixation types, short- and long-term efficacy as well as the complications have not yet reached agreement.OBJECTIVE: To discuss the efficacy of two kinds of femoral prosthesis for femoral neck fractures in hemiarthroplasty,and the application of three-dimensional CT reconstruction in displaced fractures.METHODS: Clinical data of 73 cases of femoral head fractures undergoing hemiarthroplasty were analyzed retrospectively, and divided into bone cement and biological groups. All patients were followed up for 1.5 years, and the operation indexes, hospitalization time and hip joint function were compared; the consistent degree with intraoperative findings was compared through hip three-dimensional CT and X-ray examination simultaneously.RESULTS AND CONCLUSION: (1) There was no significant difference in the effective rate between groups (P > 0.05).(2) The operation time in the biological group was significantly shorter than that in the bone cement group (P < 0.05); the intraoperative blood loss and hospitalization time in the bone cement group were significantly less than those in the biological group (P < 0.05). (3) The Harris scores in the bone cement group were significantly higher than those in the biological group at 1 month after replacement (P < 0.05); the Harris scores in the biological group were significantly higher than those in the bone cement group at 18 months after replacement (P < 0.05); while there were no significant differences between two groups at 3, 6 and 12 months after replacement. (4) The hip three-dimensional reconstruction and X-ray examination showed no error compared with the intraoperative findings, reaching 100%. (5) Our findings suggest that age, disease history and bone quality should be considered when choosing an appropriate type of hemiarthroplasty for the patients with femoral neck fractures, and bone cement prosthesis is suitable for the elder patients with severe osteoporosis; while those with good bone quality should receive biological prosthesis. Besides, the diagnosis accuracy of three-dimensional reconstruction is superior to X-ray examination, which is conductive to fully understand displaced fractures.

Objective To compare the efficacy of urinary type Ⅳ collagen( Ⅳ C), N-acetyl-β-D-glucosaminidase( NAG ), serum cystatin C ( CysC ), β2 microglobulin ( β2-MG ) in early diagnosis of diabetic nephropathy(DN) ,and to develop a multiple regression equation using above mentioned indices. Methods One hundred and eight cases of DM patients were enrolled in the study. All those DM patients were divided into two groups according to 24 hr urinary albumin excretion(UAE): non-DN group( UAE ＜30 mg/24 h)and DN group (UAE ≥30 mg/24 h). Receiver operating characteristics (ROC)curve was developed using urinary IVC, NAG,serum CysC and β2-MG,and the efficiency of the four indices for early diagnosis of diabetic nephropathy were assessed by area under the curve ROC (AUCROC). Furthermore, the regression equation of four indicators was developed. All statistical analyses were performed using SPSS 13.0. Results The levels of urine Ⅳ C, NAG,CysC,β2-MG,were(3.91±1.93)ng/ml, ( 12.20 ±3.46)U/L, ( 1.18 ±0.41 )mg/L , (2. 50 ±0. 74)mg/ml in the non-DN group, respectively; and ( 14.14 ± 11.17 ) ng/ml, ( 23.12 ± 13.57 ) U/L, ( 2.69 ± 1.69 ) mg/L and(5.21 ± 2.78)mg/ml in the DN group, respectively. There were significant differences in the comparison of the four indicators between the two groups ( Ps ＜ 0.01 ). AUCROC of Ⅳ C, NAG, CysC and β2-MG were 0. 747,0.732,0.764 and 0.823 respectively;which meant the diagnostic efficacy for DN decended from β2-MG, CysC,Ⅳ C, to NAG in order. All these indices showed significant efficiency in assisting diagnosis of early DN ( Ps ＜0.01 ). The regression equation of UAE and the four indices was: UAE = - 242.624 + 6.362IVC + 8.662NAG + 64. 622CysC + 29.488β2-MG, and the equation had statisticl significance( P ＜ 0.O1 ). Conclusion Urine Ⅳ C, NAG,serum CysC, and β2-MG showed significant value in assisting diagosis of early DN, and could be sensitive indices for DN.

Objective To evaluate the results of computer-aid customized acetabular cages for patients with severe defects.Methods Twenty-three patients (8 males and 15 females) with a massive acetabular defects were involved in the present study from January 2005 to September 2014.The average age was 64.2 years (range,46-79 years).According to the American Academy of Orthopaedic Surgeons (AAOS) classification,20 had AAOS type Ⅲ defects and three had AAOS type Ⅳ defects.The customized cages were individualized to each patient's bone defects based on the rapid prototype three-dimensional printed models.The mean follow-up duration was 66.3 months (range,24-120 months).The clinical and radiographic outcomes of all patients were assessed at 6 and 12 weeks after surgery and at once yearly thereafter.Harris hip scores were assessed before surgery and at each follow-up.Postoperative radiographs were evaluated for cage position,migration,and graft incorporation.Complications and reoperations were assessed by chart review.Results The mean Harris hip score improved from 36.2±7.9 (range,20-49) to 81.8± 8.4 (range,60-96),and there is a significant difference between pre-and post-operation (t=23.23,P＜0.001).Individualized custom cages resulted in generally reliable restoration of the hip center.The difference of horizontal distance (between the center of each hip and pubic symphysis) between bilateral sides was-3.0±6.4 mm (range,-19-8 mm).The difference of vertical distance (between the center of each hip and the line connecting the inferior border of the bilateral tear drop) between bilateral sides was 0.4±2.8 mm (range,-4.5-5 mm).No re-revisions had been conducted.None of the cups showed radiographic migration,while one cage was suspected to be loose based on a circumferential 2-mm radiolucent line.Cancellous allografts appeared to be incorporated in 22 of 23 patients.One deep infection and one superficial infection were observed and were treated with irrigation,debridement,and vacuum sealing drainage.One dislocation and one suspected injury of the superior gluteal nerve also were observed and were treated conservatively.Conclusion Individualized customized cages appears to provide stable fixation and improve hip scores at short or mid-term follow-up.

Objective To evaluate the clinical efficacy and safety of retroperitoneal laparoscopy and open surgical treatment of simple renal cyst by Meta analysis.Methods Computer retrieval of MED-LINE,Cochrane Library,EMBASE,CNKI,Wanfang and VIP databases,according to the inclusion and exclusion criteria collected and screened out a randomized controlled studies on the treatment of simple renal cysts,published from January 1,2000 to August 31,2015.Two independent authors screened out randomized clinical trials (RCTs),extracted data,assessed quality of data,and then carried out Meta analysis by Revman 5.0 software with related data.Results Twenty one studies met the inclusion criteria with a total of 2 296 patients,including 1 162 patients of retroperitoneal laparoscopy and 1 134 cases of open operation group.Compared to the open operation group,retroperitoneal laparoscopy showed shorter operation time,less bleeding,shorter hospitalization time,and earlier postoperative drainage tube extraction time.No significant difference was found in the recurrence rate of the cyst for two groups.Conclusions The clinical efficacy,safety,and complication of retroperitoneal laparoscopy in the treatment of simple renal cyst is better than the open operation.

Objective To measure the morphological parameters of the acromion with CT and to analyze their match with the hook plate. Methods From October 2009 to February 2010,spiral CT scanning (with Somatom Emotion16) and three-dimensional reconstruction of bilateral shoulders were conducted in 61 Chinese subjects.They were 24 men and 37 women,aged from 20 to 83 years (average,45.2 years).The thickness,length and width of the acromion were measured and the subacromial shape was observed with software of the CT system to analyze the match between the hook plate and the acromion.Results The mean thickness of the acromion was 0.85 ± 0.13 cm in all subjects,0.94 ± 0.12 cm in males and 0.79 ± 0.10 cm in fe males,with a significant difference between males and females ( t =2.382,P =0.202).The mean acromion length was 2.08 ± 0.20 cm in all subjects,2.09 ± 0.21 cm in males and 2.06 ± 0.18 cm in females,with no significant difference between males and females( t =1.541,P =0.129).The mean acromion width was 3.81 ± 0.52 cm in all subjects,4.34 ± 0.32 cm in males and 3.47 ± 0.25 cm in females,with a significant difference between males and females ( t =2.296, P =0.025 ). Conclusions The acromial morphology varies significantly between genders in Chinese population,particularly in the thickness and width.It is,therefore,necessary to modify the morphological parameters of the hook plate to match better the gender difference in Chinese population.It is optimal that the hook plate should allow individualized pre-moulding to enhance its therapeutic efficacy.
