Objective: To observe the improving effect of muscle regions of meridians needling method on the upper limb function in children with cerebral palsy of spastic hemiplegic type. Methods: A total of 100 children with cerebral palsy of spastic hemiplegia type were divided into a treatment group and a control group according to the visiting sequence, with 50 cases in each group. The control group was treated with conventional rehabilitation plus conventional acupuncture treatment. The treatment group was treated with conventional rehabilitation plus muscle regions of meridians needling method. The electromyography (EMG) signal values of triceps brachii and pronator teres were detected before treatment, and 3 months and 6 months after treatment. The clinical efficacy was evaluated by Peabody developmental motor scale-fine motor (PDMS-FM) and fine motor function measure (FMFM). Results: Three and six months after treatment, the EMG signal values of triceps brachii and pronator teres, grasping scores and visual-motor integrated scores of PDMS-FM and the FMFM scores in both groups increased to varying degrees compared with the same group before treatment, and the intra-group differences were all statistically significant (all P<0.05). Six months after treatment, the results of the above three items in the treatment group were all better than those in the control group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Muscle regions of meridians needling method added on the basis of conventional rehabilitation can effectively reduce the muscle tone of upper limb and enhance the muscle strength, and improve the upper limb function in children with cerebral palsy of spastic hemiplegia type. The efficacy is superior to that of the conventional rehabilitation plus conventional acupuncture treatment.

OBJECTIVETo evaluate the early clinical and radiographic outcome of scaphoid non-unions treated with Acutrak headless compression screw.

METHODSFrom January 2008 to July 2011,21 patients with scaphoid non-union were treated in our department. There were 18 males and 3 females with a mean age of (23.6 +/- 4.6) years; 12 cases were on right hand and 9 were on left. According to Herbert-Fisher classification, there were 10 cases with type D1, 7 cases with type D2, 3 cases with type D3, and 1 case with type D4. The mean time from injury to operation was (12.4 +/- 2.7) months. All patients were treated with Acutrak headless compression screw fixation (6 cases received 2 screws fixation, 15 cases received 1 screw fixation, and Matti-Russe bone grafting was applied in 7 cases). The carpal height, the scaphoid index and changes of the scapholunate angle were assessed before and after the operation. Range of motion and grip strength were recorded and the wrist function was assessed according to the Patient-Rated Wrist Evaluation (PRWE).

RESULTSAverage duration of follow-up was (21.3 +/- 3.6) months. All the patients attained radiological union in a mean time of (13.3 +/- 2.4) weeks following the operation. No obvious complications were recorded. The surgical treatment allowed the preoperative mean scaphoid index of 0.61 +/- 0.13 and the preoperative mean scapholunate angle of (59.4 +/- 6.8) degree to be improved to 0.69 +/- 0.10 and (44.3 +/- 8.2)degree postoperatively, respectively. There was a substantial improvement in grip strength and pain amelioration after surgery. The preoperative mean PRWE score of 45.2 +/- 4.7 was improved to 76.1 +/- 5.2 postoperatively. All patients returned back to the original work,the average time from surgery to work was (6.0 +/- 1.1) months.

CONCLUSIONFor scaphoid non-unions, Acutrak headless compression screw fixation can provide anatomical reduction, provide satisfactory results with a high union rate, well return of function and minimal complications in the early stage.

HSP90, which is the biomarker of cell stress and endogenous protective protein, functions as a molecular chaperone. Many client proteins of HSP90, including EGFR, Met, Raf-1, IKK and p53, play important roles in the occurrence and development of tumor. Binding of HSP90 inhibitors triggers the deactivation of HSP90, resulting in client protein degradation, and hence inhibits the tumor growth by blocking multiple targets involved in signaling of tumor proliferation. This review summarizes recent development of small molecule inhibitors bound to N-terminal of HSP90.

OBJECTIVETo evaluate preoperative application of recombinant human erythropoietin (rHuEPO) in reducing transfusion requirements in elderly patients undergoing elective surgery for femoral intertrochanteric fractures.

METHODSFrom January 2011 to December 2013,442 cases of elderly patients with femoral intertrochanteric fracture were retrospectively reviewed. According to inclusion and exclusion criteria, 119 cases were eventually included and divided into the treatment group and the control group. There were 12 males and 40 females, with a mean age (71.4 ± 12.8) years old, and the patients received preoperative administration of rHuEPO 10,000 U qod combined with iron dextran 200 mg (3 times each day). While 16 males and 51 females in control group, with a mean age (70.9 ± 16.2) years old, and the patients only received preoperative administration of iron dextran 200 mg (3 times each day). All the patients received closed reduction and PFNA-II or Internal fixation surgeries. The perioperative blood transfusion rate, average amount of blood transfusion, postoperative complications, the length of hospital stay and mortality within 30 days were compared between the two groups.

RESULTSThere were no statistical differences between two groups in the baseline indexes (P > 0.05). Overall,71 of 119 patients (59.7%) received at least one unit allogeneic blood transfusion (ABT). However,there were significant differences in perioperative ABT rates (48.1% vs 68.7%, χ2 = 4.77, P < 0.05) and the average amount of blood transfusion between treatment group and control group, which were (1.8 ± 0.4) U/pte vs (3.6 ± 1.1) U/pte (t = 2.244, P < 0.05). Postoperative hemoglobin (Hb) on postoperative days 7 and 30 was higher in treatment group than that in control group. In addition, in treatment group, Hb levels were higher on postoperative day 30 than those on admission, which were (128.2 ± 20.6) g/L vs (118.2 ± 18.9) g/L (t = 2.133, P < 0.05). There were no statistical differences in postoperative complications, the length of hospital stay and mortality within 30 days.

CONCLUSIONFor elderly patients with femoral intertrochanteric fractures undergoing elective surgery, preoperative application of rHuEPO can significantly reduce perioperative transfusion requirements, and is likely to reduce ABT-related infection, but its long-term safety remains to be evaluated.

For the first group of infants, the implementation of the lacrimal sac nasolacrimal duct massage + eye drops; for the second group of infants, carry lacrimal pressure washing treatment; for the third group of infants, the implementation of the nasolacrimal duct probing treatment.
RESULTS: The first group of children through the nasolacrimal duct sac massage + drops tobramycin eye drops treatment unobstructed 12, the cure rate was 46. 2%;The second group of children through pressurized irrigation treatment lacrimal patency by 33, the cure rate was 91. 7%; The third group of children through the nasolacrimal duct probing unobstructed 36 treatment, the cure rate was 90. 0%. The second and third group were better than the first group (χ2=15. 71, P<0. 01;χ2=15. 27, P<0. 01);the treatment effect of the second and third groups was no significant difference (χ2=0. 02, P>0. 05).
CONCLUSlON:lnfants with congenital nasolacrimal duct obstruction should distinguish between ages, taking different treatments, in order to obtain a better therapeutic effect, and lacrimal pressure washing is the preferred way of treating infants with congenital nasolacrimal duct obstruction.

Objective To study the effects of oxymatrine as inhibitor of hemorrhagic fever with renal syndrome virus (HFRSV) infection in vitro and in vivo.Methods In vitro studies,a dose of oxymatrine without cytotoxicity and 76-118 strain of HFRSV was taken to treat Vero cells in three ways:①After treated with oxymatrine for 48 h,Vero cells were attacked by HFRSV at dilution of 10-1 ～ 10-6,respectively for 24 h before changing to maintenance medium; ②Vero cells were first attacked by HFRSV of 10-1 ～ 10-6 dilution respectively,then oxymatrine was used for 48 h before changing to maintenance medium; ③Vero cells were attacked by HFRSV at dilution of 10-1 ～ 10-6 respectively,and meanwhile treated with oxymatrine for 48 h before changing to maintenance mcdium.Each dilution handled four porocytes,and four positive controls were set up at the same time.Indirect immunofluorescence assay (IFA) was performed to determine the inhibitory effect of oxymatrine in experimental group and positive control.In vivo studies,thirty 2-week-old hamsters,weighing about 30-40 g,were divided into experimental and control groups according to body weight,n =15.These aninals were inoculated intraperitoneally with HFRSV in 100TCID50(0.1 ml each); on days 4-13,0.1 ml of oxymatrine 1:100 were given to each hamster in experimental group daily by intraperitoneal injection,while the same amount of saline was given to the control ones.Lung tissue of hamsters was then dissected out to slice to be identified by immunofluorcscence stain.Results It was demonstrated that oxymatrine with the diluted fractions of 1:8 was safe in vitro.When the virus dilution of HFRSV was l0-4,compared with control groups,the differences were statistically significant in method 2 and 3 (z =-2.53,-2.53,all P ＜ 0.05),while no statistical significance in method 1 (z＝5.36,P＞ 0.05).When the virus dilution of HFRSV was 10-1 ～ 10-3,10-5,10-6,the differences were not statistically significant (z--0.00,-0.32,-0.19,4.21,4.21,all P ＞ 0.05).In vivo studies,compared with control group,the differences were statistically significant in experimental group (z =-3.85,P ＜ 0.05).Conclusion Oxymatrine significantly inhibites HFRSV.

Objective To detect genetic polymorphism of myeloperoxidase (MPO) gene and catalase (CAT) gene and their activities, and to analyze their relationship with arsenic poisoning caused by coal-burning. Methods One hundred and thirty arsenic poisoning patients were chosen as case group in Jiaole Village, Xingren County, Guizhou Province(an endemic area). One hundred and forty healthy residents living in 13 km away were chosen as control group. Their blood was collected. Polymerase chain reaction-restriction fragment length polymorphism technique(PCR-RFLP) was used to detect polymorphism of MPO-463G/A and CAT-262C/T. Ultraviolet spectmphotometer method was used to detect myeloperoxidase activity. Chromatometry method was used to detect catalase activity. Results The genotype frequency of MPO-463G/A at GG, GA, AA site was 47.24%(60/127), 44.09%(56/127),8.67% (11/127) in case group and 42.34% (58/137),48.17% (66/137)1,9.49% (13/137) in control group, respectively. The difference between the two groups was not significant(χ2 = 0.642, P > 0.05). The genotype frequency of CAT-262C/T, at CC, CT, TT site was 65.60%(82/125),28.80%(36/125),5.60%(7/125) in case group and 76.51%(101/132), 18.94% (25/132) ,4.55% (6/132) in control group, respectively, without significant difference (χ2 =3.845, P>0.05). The relationship between polymorphism of MPO-463G/A and CAT-262C/T and the risk of arsenic poisoning was not found in this study(ORadj= 1.36, 95%CI: 0.74-2.50 for MPO; ORadj=1.35, 95%CI: 0.69-2.63 for CAT). The activities of MPO and CAT were (25.30±8.70)U/L and (2.80± 1.09)×103 U/L in case group, while (22.76±7.59)U/L and (3.90±1.01)×103U/L in control group with a significant difference(F=0.760 for MPO, F=0.855 for CAT, all P < 0.05). The genotype of MPO-463G/A and CAT-262C/T was not found to have relationship with the activities of MPO, CAT(F=1.312,2.822 for MPO; F= 0.151,0.036 for CAT, P>0.05). Conclusions Genetic polymorphism of MPO-463G/A and CAT-262C/T is not found to have relationship with arsenic poisoning. Arsenic can lead to the change of MPO and CAT activity, which, however, may not be affected by MPO-463G/A and CAT-262C/T polymorphism.

OBJECTIVETo investigate the early clinical efficacy of induced membrane technique for reconstruction of large bone defects after debridement in adults with chronic osteomyelitis of limbs.

METHODSFrom March 2010 to March 2012,a total of 23 adult patients with chronic osteomyelitis of limbs were treated in our department. There were 15 males and 8 females, with a mean age 35.2 years old (ranged from 26 to 49 years old). Sixteen patients had open fracture history. According to the lesion site, there were 12 cases of tibia, 7 cases of femur, 3 cases of humerus, and 1 case of both radius and ulna. Among them, 19 patients had diseases in diaphysis and 4 patients in the metaphysis. The mean interval from infection to operation was 6.9 months (ranged from 4 to 13 months). All the patients were treated by using induced membrane technique. The follow-up evaluation included clinical complications, time of bone healing and limbs function. The Chinese version of SF-36 scores was used in the assessment of quality of life pre- and post-operation.

RESULTSThe average duration of follow-up was (27.6 ± 5.3) months (ranged from 18 to 43 months). Two patients had postoperative flap edge necrosis, 1 patient had superficial iliac incision infection, no obvious complications were recorded. Twenty patients obtained radiological union at a mean time of 4.6 months (ranged from 3 to 7 months). Among them, 16 patients treated with lower limbs surgery achieved full weight-bearing at about 5.2 months (ranged from 4 to 8 months) postoperatively. Four patients suffered from reinfection during follow-up, but 3 of them achieved complete bone healing after the second surgeries with induced membrane technique. At the final follow-up, there was a substantial improvement in each dimension scores and total scores of SF-36 as compared with those before surgery.

CONCLUSIONWhen treating with adult chronic osteomyelitis of limbs, the induced membrane technique can effectively reconstruct large bone defects after debridement, significantly shorten treatment cycle, provide satisfactory results with minimal complications, promote good recovery of limbs function and require relatively simple operation technique.
