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.

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%.

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 .

We sought to determine the efficacy of ramosetron in the prevention of nausea and vomiting during emergency cesarean delivery under spinal anesthesia with strict controls of causative factors.A total of 206 parturients participated in a randomized,single-blind and placebo-controlled trial.They received an intravenous injection of either ramosetron 0.3 mg or normal saline immediately after cord clamping.The primary outcome was the presence of postdelivery nausea and vomiting.Secondary outcomes included the need for rescue antiemetic,hypotension,pain and adverse effects.The incidence of postdelivery nausea and vomiting was 10.7％ in the ramosetron group vs.28.2％ in the control group (P ＜ 0.01 ).The incidence of intraoperative hypotension and postdelivery was similar in both groups.The incidence of postdelivery pain and the requirement for rescue antiemetic were similar in both groups.Ramosetron 0.3 mg is effective in the prevention of postdelivery nausea and vomiting during cesarean delivery.

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 study the similarities and differences of information needs between cancer patients treated with radiotherapy and chemotherapy, analyze the causes for cancer patients' different choices, and provide reasonable and disease-related information for cancer patients. Methods A total of 102 and 119 cancer patients treated with radiotherapy and chemotherapy relatively were asked to complete the questionnaire (IPQCP+2) and two questions about the total information capacity and content requirements. Results Two groups had different needs of therapeutic information and treatment in IPQCP. Cancer patients treated with chemotherapy needed more widely-ranged information than patients underwent radio-therapy. Conclusions Most of cancer patients treated with radiotherapy and chemotherapy need to be informed of disease-related information, among which the content of therapeutic information and total information is relative to the treatment. Nurses should provide disease-related medical information based on their different needs, as to improve the life quality of cancer patients.

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.

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

Objective To investigate the clinical characteristics of compression of upper trunk brachial plexus.Methods Clinical data of 27 patient with compression of upper trunk brachial plexus were retrospective analyzed.Results All cases showed sensory disturbance in radialis sides of upper extremities.13 cases accompanied by ipsilateral breast or mid-back pain.All cases showed severe tenderness at the middle point or at the juncture between center and lower third part of posterior edge of the ipsilateral sternocleidomastoid muscle.The tenderness always radiated to the involvement limb,the affected breast or the mid-back areas.Symptoms aggravated in 55.6%(15/27)cases when the suffering limbs were set in abducens and rotated externally position.25.9%(7/27)cases showed decreased nerve conduction velocities and 7.4%(2/27)showed abnormal motor unit potential.Radioactive ray studies found no abnormalities corresponding to the symptoms.Nerve blockade at the tenderness point together with physiotherapy were effective.4 weeks after treatment the total effective rate was 82.5%(23/27),ineffective rate was 14.8%(4/27).Conclusions The features of upper trunk brachial plexus entrapment neuropathy including:paraesthesia in radialis side of upper extremities and severe tenderness at the middle or center-lower part third of posterior edge of ipsilateral sternocleidomastoid muscle which radiates to the involvement limb,mid-back or breast.Local nerve blockade combined with physiotherapy was effective,and also one of the way for differential diagnosis.
