Objective To quantify the effect of rehabilitation training on cardiopulmonary function and the quality of life of patients with coronary heart disease after percutaneous coronary intervention (PCI). Methods Sixty-nine patients after PCI were randomly divided into three groups. Those in group A were given conventional medical therapy; group B had additional walking exercise; group C had both additional respiratory training and the additional walking exercise. Treadmill exercise tests, pulmonary function examinations and a health questionnaire were used to evaluate cardiopulmonary function and quality of life after three months of treatment. Results After three months of treatment cardiopulmonary function and quality of life had improved significantly in groups B and C, and there was significant difference between groups B and C. Conclusion Walking and respiratory function training can improve cardiopulmonary function and quality in life after PCI.

Patent ductus arteriosus (PDA)is a common disease among premature neonates and the management of which has always been a challenge to the neonatologists. Early treatment has been advocated as the first-line approach, and drug induced closure is yet the most effective, inexpensive, and convenient method. During the last two decades,indomethacin was often given as conservative treatment, and its closure rate in PDA was approximately 46% ～ 89%. However,indomethacin may increase the number of undesirable or harmful effects including renal damage, intraventricular hemorrhage, necrotizing enterocolitis, and enterobrosis,etc. Recently,ibuprofen is rapidly emerging as a new promising drug for treatment of PDA in preterm infants with closure rate of 73.0% ～95.5%. It is used as standard therapy to close PDA,and it has less influence on the hemodynamics of kidneys, brain and gastrointestinal tract. The surgery is needed in patients with drug treatment failure and cardio-pulmonary function damage.

Objective To evaluate the role of phosphatidylinositol 3-kinase (PI3K)/protein-serinethreonine kinases (Akt) signaling pathway in dexmedetomidine postconditioning-induced reduction of myocardial ischemia-reperfusion (I/R) injury in rats.Methods Seventy-two healthy male Sprague-Dawley rats,aged 4-5 months,weighing 200-240 g,were heparinized and anesthetized with intraperitoneal pentobarbital sodium 40 mg/kg.Their hearts were rapidly excised and perfused in a Langendorff apparatus with oxygenated (95％ O2-5％ CO2) K-H solution at 0-4℃.The isolated hearts were randomly divided into 6 groups (n =12 each):control group (group C),group I/R,dexmedetomidine postconditioning group (gruop D),solvent group (group DMSO),PI3K inhibitor LY294002 group (group L) and LY294002 + dexmedetomidine postconditioning group (group L + D).After a 20 min stabilization period,the hearts were continuously perfused with K-H solution for 120 min in group C and were subjected to 30 min of global no-flow ischemia followed by 90 min of repeffusion in the other groups.Dexmedetomidine 100 nmo/L was added during the initial 30 min of reperfusion in D and L + D groups.LY294002 15 μmol/L was added in L group.0.02％ DMSO containing 15 μmol/L LY294002 was added in L + D group.0.02％ DMSO was added in DMSO group.HR,left ventricular end-diastolic pressure,left ventricular developed pressure and ± dp/dtmax were recorded at the end of 20 min stabilization and 15,30 and 90 min of reperfusion.The expression of phosphorylated Akt (p-Akt) and Akt was measured at 30 min of reperfusion.Myoeardial infarct size was determined using TTC staining at 90 min of reperfusion.Results Compared with group C,HR,left ventricular developed pressure and ± dp/dtmax were significantly decreased,and left ventricular enddiastolic pressure and myocardial infarct size were increased in the other 5 groups,and the expression of p-Akt was significantly up-regulated in group D (P ＜ 0.05).Compared with group I/R,HR was significantly decreased at 15 and 30 min of reperfusion,the expression of p-Akt was up-regulated,and myocardial infarct size was decreased in group D (P ＜ 0.05).Compared with group D,the expression of p-Akt was down-regulated,and myocardial infarct size and HR was increased in L + D group (P ＜ 0.05).Conclusion Dexmedetomidine postconditioning attenuates myocardial I/R injury throuth activating PI3K/Akt signaling pathway in rats.

Objective To observe the serum estradiol level in newborns at different gestational age and the infants with retinopathy of prematurity (ROP), and explore the relationship between these changes and ROP. Methods A total of 178 newborns hospitalized in the Children's Hospital of Fudan University were enrolled in the study. They were divided into three groups based on the gestational age, ＜ 32 weeks group, 32-37 weeks group and term group. The three groups were further divided into non-oxygen and oxygen subgroups. Infants with birth weight less than 2000 g were evaluated for ROP and those diagnosed as ROP were under ROP group (n=6). Serum estradiol levels were measured every week from birth to discharge with radioimmunoassay. Results Serum estradiol levels of newborns quickly declined after birth. In the non-oxygen subgroups, serum estradiol levels in 32 ～ 37 weeks group were remarkably higher than those of term group in the first week [(3506±1376) pmol/L vs (1717±179) pmol/L,P＜0. 05] and the third week [(1431±92) pmol/L vs (996±102) pmol/L, P＜0. 05]; Serum estradiol levels in ＜32 weeks group was only remarkably higher than those of term group in the first week [(3173± 1369) pmol/L vs (1717± 179) pmol/L,P＜0. 05]; Serum estradiol level in the ＜32 week group was (560±355) pmol/L, lower than that in the 32-37 weeks group [( 1124 ± 128) pmol/L] (P＜0. 05). There was no difference of serum estradiol levels in the oxygen and non-oxygen subgroups of the same group. There was no significant difference of serum estradiol levels between the ROP group and ＜32 weeks group. Serum estradiol levels in ROP group was lower than that of premature group without ROP at 29 and 32-36 weeks of corrected gestational age, but no statistical difference was shown. Conclusions Very low serum estradiol level in premature infants may be related to the development of ROP, but further clinical studies are required.

Objective To investigate the effect of boningmycin on expression of capsid protein L1 and serum immune factors in cervical HPV infection patients.Methods 60 patients with cervical HPV infection were divided into experimental group and control group, 30 cases in each group.The control group were given recombinant human interferon α2b suppository, 100 000 IU, once every other day, and the experiment group were given boningmycin 300 mg intramuscular injection,once every other day.Treatment of 10 times for a course,2 consecutive courses After treatment, the HPV capsid protein L1, serum TNF-α, IL-2, IFN-αand HPV were compared.Results Compared with control group after treatment, the percentage of HPV capsid protein L1 increased ( P <0.05 ) , serum TNF-α, IFN-αlevels increased ( P <0.05 ) , IL-2 decreased ( P <0.05 ) , and HPV positive rate decreased( P <0.05 ).Conclusion Boningmycin could reduce the percentage of capsid protein L1 in patients with cervical human papilloma virus infection, elevate serum TNF-αand IFN-αlevels, reduce the level of IL-2 and HPV positive rate.

Objective To analyze and evaluate the relationship between hepoatocelluar carcinoma incidence and hepatitis B e antigen (HBeAg) expression in choronic hepatitis B (CHB) patients with long-term treatment of nucleoside analogue therapy.Methods The clinical data of 56 CHB patients with long-term treatment of nucleoside analogue therapy except for hepoatocelluar carcinoma (experimental group)were summarized retrospectively,and all patients underwent anti-viral therapy with no less than 5 years.The clinical data of 56 CHB patients without anti-viral therapy in the same period (control group) were collected.The risk factors of hepoatocelluar carcinoma were analyzed.Results The incidence of hepoatocelluar caroinoma was 7.14％ (4/56) in experimental group and 19.64％ (11/56) in control group,and there was significant difference (P ＜ 0.05).The incidence of hepoatocelluar carcinoma was 0 in patients with positive HBeAg without cirrhosis (36 cases) in experimental group and 1/8 in patients with negative HBeAg without cirrhosis in experimental group,and there was significant difference (P＜ 0.05).Conclusions Long-term treatment of nucleoside analogue therapy can reduce but bot eliminate the hepatocellular carcinoma risk in patients with CHB,especially in those with negative HBeAg.HBeAg negativity is a significant risk factor for the development of hepallerular carcinoma in CHB patients without liver cirrhosis.

Objective To quantify the effect of gradual respiratory functional training on the lung function and quality of life (QOL) of patients convalescing from Guillain-Barré syndrome (GBS). Methods Thirty-two GBS patients were randomly divided into two groups a control group which received routine nursing and a respiratory function training group.The training was in three stages:thoracic or/and abdominal respiration,deep breathing and respiratory exercise.After 2 and 4 months of treatment,the 16 min walk test and the SF-36 health questionnaire were used to evaluate the subjects' lung function,motor capacity and QOL. Results After 2 and 4 months of treatment,vital capacity (VC),forced vital capacity (FVC),forced expiratory volume in one second (FEV1) and maximal ventilatory volume (MVV) had all improved significantly in the training group.Their 6 min walk distances and QOL ( in all 8 domains) had also improved significantly.The average VC.FVC.FEV1 and MVV in the control group all decreased slightly but the decreases were not significant.Their 6 min walk distances had improved significantly,however,as had the physical function,mental health.psychological role,physical pain and integrated health domains of their QOL. Conclusion Training the respiratory functional of GBS patients during convalescence can prevent the lung function decay due to muscle weakness,and can also improve motor ability and QOL.
