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.

With the development of imaging techniques of CT , MRI, and PET-CT, the clinical applications of the above-men-tioned imaging modalities have become increasingly mature , which makes early diagnosis rate of pancreatic cancer has been improved to some extent.However, choosing the most effective and economical imaging method need to be addressed in the clinical work .This pa-per will show the research progress of imaging in pancreatic carcinoma detection at home and abroad .

Major points: Zhongwan (CV 12), bilateral Zusanli (ST 36) and Neiguan (PC 6); for excessive cold-dampness, plus Pishu (BL 20) and Sanyinjiao (SP 6); for Liver-qi affecting stomach, plus Yinlingquan (SP 9) and Taichong (LR 3); for deficiency of both spleen and sto mach, plus Pishu (BL 20) and Weishu (BL 21). 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%.

Objective To study the effect of restraint and watered stress of different durations on the gastric empting in rats. Methods 48 male SD rats (weight ±150 g) were divided randomly into 6 groups with 8 in each. The experimental rats were restrained and watered in 23℃ water box for 1 h/d, while the controls were free. The body weight, general conditions and behavioral indexes of the rats were observed and recorded. The gastric empting rate was measured in rats with semi-solid diet after 3 d,7 d and 28 d during the statistically significant differences among different groups of different stress groups,and between the 3 d test group and 3 d control group. The gastric empting rate was higer in the 7-day test than in 7 d controlled group, lower in the 28 d test group than 28 d control group. Conclusion Different chronic stress can cause changes of gastric empting rate. With the prolonging of stress time, the empting rate is rising and then decending.

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.

Objective To detect the difference of the light sensitivity in the central visual field between normal people and type Ⅱ diabetic patients without diabetic retinopathy , and evaluate the effect of perimetric examination in early diagnosis of diabetic retinopathy. Methods The light sensitivity at the 80 locations in the central field was measured by Dicon field analyzer (model TKS 4000) in 76 normal eyes of 44 normal volunteers aged from 45 to 72 years and 75 eyes of 40 type Ⅱ diabetic patients without retinopathy aged from 46 to 71 years. Results For the diabetic patients without diabetic retinopathy, the light sensitivity of locations decreased by 4 8 dB,and there were some decreased light sensitivity areas. The mean light sensitivity of three zones of the central field had significant reduction in the diabetic patients as compared with the control group( P

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.

Objective To investigate the changes of serum interleukin 8(IL-8) level in children with thyroid disfunction and its clinical significance in children with autoimmune thyroid disease(AITD).Method Serum IL-8 of 30 children with hyperthyroidism,16 children with hypotyroidism and 20 health children were detected by double antibody enzyme linked immunossorbent assay(ELISA).Results Serum IL-8 levels in hyperthyroidism and hypothyroidism children were significantly higher than that in controls(P0.05).With the remission of the diseases, IL-8 levels decreased; there was a significant difference between serum IL-8 levels in patients before and after therapy (P

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.
