Objective To study the method of surgical correction for pelvic obliquity secondary to leg length inequality. Methods Pelvic equilibrium operation is designed to correct the fixed pelvic obliquity, equilibrate the two lower limbs by bilateral iliac osteotomies with transfer of a block of iliac bone from the normal ilium into the abnormal ilium of the contralateral side. This procedure also corrects the associated acetabular dysplasia. Results In this series of 32 patients, none was lost to follow-up. Thirty-two patients, 19 males and 13 females, whose ages ranged from 14 to 34 years with a mean of 22 years, underwent surgery; twenty-four cases had fixed pelvic obliquity and acetabular dysplasia secondary to a short limb following anterior poliomyelitis. The deformities in seven cases were due to severe tuberculous infection in childhood which had resulted in a fixed adducted ankylosed hip. The pelvic equilibrium was caused by trauma in one case. During the review, the minimum time from surgery was 2 years and 6 months, and the maximum 13 years and 6 months with a mean of 6 years and 8 months. The results were excellent. Preoperatively, 29 patients walked on crutches, and postoperatively, 25 patients could walk unaided, one with a stick and three on single crutch. In this paper, we also presented the associated experiment research of pelvic equilibrium operation. Conclusion Pelvic equilibrium operation has been proved to be a new effective surgical correction method of pelvic obliquity secondary to leg length inequality.

Background and purpose: Cervical cancer is one of the most common malignant tumors and poses a great threat to women's fitness. Monitoring its present status and variations over the past 3 decades could provide scientific basis for prevention and control strategies of cervical cancer in China. Methods: This study collected the mortality rates of cervical cancer data in Chinese women from 1987 to 2014, described the features and trends of age-standardized rates and truncated rates, and estimated the variations via joinpoint regression models. Results:The mortality rates of cervical cancer for rural women were roughly higher than those for urban women. It showed downward trends for both urban and rural women, and the average rate of decrease for rural women (AAPC=3.94%, P<0.01) was higher than that for urban women (AAPC=1.79%, P<0.01). The gap between urban and rural areas was narrowing, with urban rates exceeding rural rates after 2010. The mortality rates of cervical cancer increased with time for urban women aged from 30 to 54, decreased with time for the elderly urban women and all the rural women. Conclusion: The overall mortality rates of cervical cancer took a desirable turn in China over the past 3 decades, while the status for the middle-aged urban women was getting worse as well as the elderly in both urban and rural areas during the past 10 years.

Objective: Extracting ephedrine and berberine from the water extract of Ephedra Herba and Rhizoma Coptidis. Methods: Modified PVA was used as separating membrane and separated alkaloids. Results: A colorless ephedrine aqueous solution was obtained when extraction time was less than 8 hours; while a three constitution solution was obtained when time of extraction is over 8 hours. So is Rhizoma Coptidis. The membrane is hardly fouled. Conclusion: Purity of alkaloids from Herba Ephedra and Rhizoma Coptidis by membrane separation is Superior to that by alcoholic sediment but amount of alkaloids is reverse.

The free membrane of Eudragit L100/S100 which is pH-sensitive, colon-specific was prepared by plane casting films. The film humidity, species and amount of plasticizers, the ratio of membrane material was investigated. The rate of membrane permeability and mechanical properties were used as indicators of orthogonal experiment, and its related properties were studied. The results show that the mechanical properties of the membrane and phragmoid capacity are the best when 30% TEC was used as plasticizer; the ratio of membrane material have little effect on the rate of membrane permeability and mechanical properties. By adjusting the species and amount of plasticizers, the ratio of Eudragit L100/S100, the free membrane which is colon-specific can be obtained.

Objective To investigate the clinical features of Crohn's disease(CD)and ulcerative colitis(UC)according to the Montreal classification.nethods The clinical data of 110 cases of CD or UC were reviewed.The age at diagnosis.location and clinical behavior were assessed with the Montreal criteria.Results CD patients diagnosed at an age younger than 16 years were rare(3.6%),the majority of the CD patients was diagnosed at 17-40 years old(65.5%).Although ileocolon lesions were most common in the patients diagnosed at 17-40 years old(37.3%),yet ileum lesions were a little more than those of other parts of digestive tract in the patients diagnosed after 40 years old(14.5%),the difference was not significant(P=0.054).Stricture frequently occurred(50.4%),especially when the lesions were located at ileum or ileocolon.Perforation rarely happened(5.3%).There was no significant difference between different location groups for clinical behaviors(P=0.096).The incidence of stricture or perforation was almost same among different age groups(P=0.984).UC patients mostly presented with mild or moderate symptoms even in the group with extensive lesion.UC patients with severe symptoms were rare(6.8%).There was no significant difference in severity between the groups with different extent of lesion (P=0.056).Conclusions The majority of CD patients was diagnosed at 17-40 years old.Stricture is much more than perforation,penetrating,occurring mostly at ileum.UC patients mostly present mild or moderate symptoms,no matter how extensive the lesion is.The extent of the lesion detected with coloscopic examination is not correlated to the severity of clinical manifestations.

ObjectiveTo investigate the effect of N-acetylcysteine on lung injury induced by cardiopulmonary bypass(CPB) in dogs.MethodsThirty-six healthy adult mongrel dogs of both sexes weighing 15-16 kg were randomly assigned into 2 groups (n =18 each):CPB group (group C) and N-acetylcysteine group(group N).Lung injury was produced by CPB.In group N N-acetylcysteine 150 mg/kg was injected iv immediately before CPB,followed by infusion at 20 mg· kg-1 · h-1 until 60 min after termination of CPB.Blood samples were taken from femoral artery before CPB (T0,baseline),30 and 60 min after termination of CPB (T1,T2 ).Oxygenation index ( OI =PaO2 ÷ FiO2 ) and respiratory index (RI =PA-(a) DO2 ÷ PaO2 ) were calculated.Six animals were sacrificed at each time point.Lung specimens were obtained for microscopic examination,and determination of transforming growth factor-β1 (TGF-β1) mRNA expression,MDA content and SOD activity.ResultsCPB significantly increased RI,MDA content and TGF-β1 mRNA expression and decreased OI and SOD activity at T1 and T2 as compared with the baseline values at T0 in group C.N-acetylcysteine administered before and during CPB significantly attenuated CPB-induced above changes in OI,RI,MDA content,SOD activity and TGF-β1 mRNA expression.Microscopic examination showed that N-acetylcysteine significantly ameriorated CPB-induced lung damage.ConclusionsN-acetylcysteine administered before and during CPB can attenuate CPB-induced lung injury by inhibiting lipid peroxidation response and down-regulating TGF-β1 expression.
