Forty-six cases of diabetic gastric disorder were treated with acupuncture and 30 cases got marked effect, 16 cases got effect and the total effective rate reached 100%.

Pulmonary valve stenosis (PS) is a relatively common congenital heart disease,and there are 2 treatment methods of surgical operation and intervention.Percutaneous balloon pulmonary valvuloplasty (PBPV) was applied successfully in children with PS for the first time by Kan.For more than 30 years,with the update of intervention equipment,improvement of operation method and accumulation of clinical experience,the application of PBPV continuously has made new progress.Most of the previous reports of the PBPV were for the immediate and short-term efficacy,while long-term follow-up data and some special types of PS review research were less.Now,combined with PBPV clinical data and long-term follow-up study in recent years,an overview of the application progress of PBPV including indications,methods,curative effect and follow-up,prevention and cure of complications and some special type of PS are provided.

[Objective]To evaluate the effect of bone cement oscillator on increasing bone cement-bone interface binding intensity.[Method]Sixty fresh femoral bones of adult pig were randomly divided into experiment group and control group under the 30%,50%,70% ultimate shear strengh of the cement/bone.There were 10 samples in each subgroup.Mechanics test was performed by MTS-810 material testing machine,and the binding intensity of bone cement-bone interface in oscillating cement-bone interface binding intensity in experiment group was compared with control group.[Result]Mechanics test showed bone cement group were significantly stronger than control group under the 30%,50% ultimate shear strengh of the cement-bone(P 0.05).[Conclusion]Bone cement oscillator can increase binding intensity of bone-cement interface,and effectively reduce long-term aseptic loosening of artificial prostheses.

Objective: To explore the feasible methods for item selection of TCM syndrome scale.Methods:Elderly hypertension with syndrome of kidney qi deficiency was selected as example.The symptoms and signs of elderly hypertension patients were statistically analyzed with clinical epidemiological investigation on the basis of discussion among focus group and expert consultation.Six selection methods were used,such as correlation coefficient method,dispersion tendency method,factor analysis method,etc.Results:18 Items were selected in the end and constituted the preliminary scale of kidney qi deficiency of elderly hypertension.Conclusion:Only if combine subjective and objective selection methods,use kinds of proper statistical methods and master the scale of preserving items,can we acquire good reliability and validity of scale.

Objective:To observe the position of the third molar in the neolithic adults about 6 000 years ago.Methods:On the basis of the maxillary and mandibular specimens preserved in Banpo museum,200 maxillary and mandibular specimens with 383 third molars,187 maxillary and 196 mandibular,were observed for the eruption of the third molar.The teeth in the non-eruption group were further divided into impact group and congenital absent group according to the third molar germ presence testified by X ray.Results:The congenital absent rates of maxillary and mandibular third molar were 26.74% and 17.35%,while the impact rates of maxillary and mandibular third molar were(2.67%) and 14.79% respectively.Conclusion:Both the congenital absent rate and the impact rate of the third molar in neolithic era adults are lower than those in modern,the impact and congenital absence of the third molar are part of degradation of masticatory organ with whole humanity progressing.

AIM: To study the clinical effect of implantation of multifocal intraocular lens ( lOL ) combined with cataract extraction and lOL in cataract patients.
●METHODS:A total of 86 cases ( 86 eyes ) of cataract patients admitted to our hospital from Feb. 2014 to Mar. 2015 were divided into two groups according to the order of admission, each of 43 cases. The 43 patients with cataract extraction combined with non spherical astigmatism correction type monofocal lOL implantation for the treatment as the control group, the other 43 patients with cataract extraction combined with aspheric toric multifocal lOL implantation were treated as the observation group. After 1y of follow- up, the visual acuity, astigmatism and the contrast sensitivity of the two groups were observed.
●RESULTS: There was no difference in visual acuity between two groups (P>0. 05). Postoperative observation group of uncorrected near visual acuity ( UCNVA ) was significantly better than the control group (P<0. 05), and the other indexes were not different (P>0. 05). There was no difference in astigmatism between the two groups before and after operation ( P> 0. 05 ). There was no difference in contrast sensitivity between two groups ( P>0. 05). The contrast sensitivity of the control group was better than that of the observation group (P<0. 05), and the rest had no difference (P>0. 05).
● CONCLUSION: Astigmatism correction multifocal intraocular lens on corneal astigmatism after surgery has a good effect, the naked eye near visual effect is better, the rest of the visual acuity is stable, good visual quality, worthy of clinical application and promotion.

BACKGROUND:As bone marrow mesenchymal stem cel s can be differentiated into osteoblasts under certain induction conditions, autologous bone marrow mesenchymal stem cel s can be implanted into the bone nonunion site of bone fracture. This new technology garners increasing attention of orthopedic clinicians.
OBJECTIVE:To summarize the clinical efficacy of transplantation of bone marrow mesenchymal stem cel s in the treatment of bone nonunion of limb fractures.
METHODS:A computer-based search of Foreign Medical Journal Ful-Text Service and CNKI databases was performed for articles related to bone marrow mesenchymal stem cel s for treatment of bone nonunion of limb fractures published from 1998 to 2014 using the keywords of“bone marrow stem cel s (BMSCs), stem cel transplantation (SCT), nonunions, tissue engineering”in English and Chinese, respectively. Literatures with repetitive content and lack of originality were excluded. A total of 36 literatures were obtained for further analysis. RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cel s are transplanted into the end of bone nonunion, and then can be induced to differentiate into osteoblasts to repair bone nonunion and bone defects,
laying a theoretical basis for clinical application. Bone marrow mesenchymal stem cel s can repair bone defects, which provides an effective method and material to promote fracture healing. Transplantation of bone marrow mesenchymal stem cel s is safe and effective for treatment of bone nonunion of limb fracture.

Objective To observe the effects of salmeterol/fluticasone on the bone metabolism and bone density of the patients with moderate COPD and whether the effects is relate with inhaled corticosteroid course. Methods Sixty pa-tients with COPD were divided into 2 groups by random digit table. Patients in experimental group (n=30) were given conven-tional therapy with salmeterol/fluticasone one inhale(bid) for continuously 12 months while patients in control group (N=30) were given conventional therapy without any glucocorticoid.The bone mineral density (BMD) of the femoral triangle in all patients were measured by DXA before therapy, 3 months and 12 months after therapy. At the same time, biochemical indi-cators that are correlated with bone metabolism include bone gla protein (BGP) and alkaline phosphatase (ALP) were mea-sured by radioimmunoassay. Results The BMD, BGP and ALP of patients in experimental group and in control group be-fore therapy, 3 month and 12 month after therapy were compared. There is no significant difference (P>0.05) between these two groups before therapy and after 3 month but significant difference was shown after 9 months (P<0.05). Conclusion Short period inhaling salmeterol/fluticasone in patients with COPD is safe. But long-term inhaling salmeterol/fluticason may lead to decline of the bone density in patients with COPD.
