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.

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.

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.

Objective To apply robotic surgery of early ovarian malignancy tumors clinically and evaluate its feasibility in management for early ovarian cancer. Methods Using the da Vinci robotic surgical system, seven patients with early ovarian malignancy tumors (stage Ⅰ) underwent robotic surgery from April 2012 to September 2013. The average age was 45.7 years. Robotic surgeries approaches contained salpingo-oophorectomy,para-aortic lymphadenectomy, pelvic lymphadenectomy, omentectomy and appendectomy. Perioperative and follow-up clinical data were recorded. Results All robotic surgeries were successfully completed without the conversion to laparotomy. The mean operative time was 225 minutes (100-330 minutes). The average estimated blood loss was 171 ml (20-600 ml). No patients received blood transfusions. No intraoperative and postoperative complications were observed. The average number of pelvic lymph node dissected were 18.3 (11-34). The average number of para-aortic lymph node dissected were 3.7 (3-4). The mean follow-up time was 26.0 months after surgery (20-36 months). Currently, all patients had no tumor recurrence and survived. Conclusion Robotic surgery is feasible as a novel alternative approach in the treatment of early ovarian malignancy tumors.

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.

Objective To study the clinical significance of urinary type Ⅳ collagen(IVC)and UmAlb/UCr ratio in the diagnosis of early diabetic nephropathy. Methods We collected 52 cases of diabetes(group A)without DN(UAE ＜30 mg/24 h),35 cases of diabetes(group B)with early DN(UAE as 30-300 mg/24 h),and 50 cases of healthy controls. The differences of urine IVC,UmAlb/UCr were compared among group A,B and the control group. ROC curve was used for evaluating the use of urine IVC and UmAlb/UCr in the diagnosis of early DN. The correlation of urine IVC and UmAlb/UCr with UAE were investigated,and linear model curve were established. IVC in urine was detected by chemiluminescence,UmAlb was detected by immunoturbidimetric assay,UCr was detected by enzymatic. Statistical analysis were performed with SPSS13.0 statistical software. Results The urine IVC testing of group A,B and the control group were(2. 64 ± 0. 91),(3.91 ± 1.93)and(10. 08 ± 6. 50)μg/L,respectively. The UmAlb/UCr(mg/mmol)testing of group A,B and the control group were(1.50 ± 0. 40),(2. 58 ±2. 10)and(17.95 ± 13. 38)mg/mmol,respectively. Urine IVC and UmAlb/UCr were significant difference between group A,B and the control group(Ps ＜ 0. 01);the ROC area under the curve(AUCROC)of urine IVC and UmAlb/UCr were 0. 724,0. 945,the two indicators for early diagnosis of DN were significant(Ps ＜ 0. 01);The pearson correlation coefficients of the urine IVC and UmAlb/UCr were 0. 529,0. 919 ,respectively. They were positive and significant correlation(Ps ＜ 0. 01),On the basis of the correlation coefficient and linear model fitting curve with the UAE,the relationship of UmAlb/UCr with the UAE was better than that of IVC. Conclusions Urine IVC and UmAlb/UCr ratio,which significantly assists diagnosis in diabetic nephropathy ,can be used as a sensitive diagnostic indicator of diabetic nephropathy. Moreover,the relationship of UmAlb/UCr with the UAE is better than that with IVC.

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 assess the functional restoration in patients with developmental dysplasia of the hip (DDH) who underwent hip resurfacing arthroplasty and to determine whether greater abduction angle of the acetabular component is relat?ed to larger diameter of femoral head component. Methods We reviewed 34 DDH cases (9 hips of 8 males and 25 hips of 24 fe?males, mean age 44.6±11.85 years at the time of surgery) on whom we performed hip resurfacing arthroplasty (HRA) from October 2006 to September 2009. The total hip Arthroplasty (THA) group was consisted of 35 DDH cases (8 hips of 8 males and 27 hips of 25 females, mean age 43.7±10.4 years at the time of surgery). All operations were performed by the same doctor over the same peri?od. Assessment of the functional hip scores was conducted by Harris Hip Scores. A radiographic study was also performed to evalu?ate the implants stability and abduction angle of the acetabular components. All the data was analyzed with Kolmogorov?Smirnov method. Results The mean follow?up was 6.2 years in the HRA group. The Harris Hip Score improved from 54.9±13.2 to 97.3± 6.2 after the surgery. The mean abduction angle of the acetabular component was 51.6° ± 5.33°, hip flexion was 127° ± 6.9° and mean diameter of femoral head was 46.5±1.5 mm. The mean follow?up was 5.9 years in the THA group. The Harris Hip Score im?proved from 51.6±19.7 to 95.6±7.9 after the surgery. The mean abduction angle of the acetabular component was 43.9°±4.90°, hip flexion was 117°±4.2°. There was no failure of the prosthesis, peri?prosthetic fracture and infection in either group. There was sig?nificant difference in the abduction angle of the acetabular component (P<0.05) and flexion of the hip between the two groups (P<0.05). Conclusion Patients in the HRA group had a better functional restoration and larger range of motion. Furthermore, a larger diameter of femoral head component could be achieved by placing the acetabular component in a greater abduction angle, which may contribute to a better long?term stability.
