Familial spontaneous pneumothorax(FSP) is a specific type of primary spontaneous pneumothorax.FSP means there are more than one individuals develop pneumothorax and is a rare inherited disease.FSP is different from primary spontaneous pneumothorax in several clinical manifestations.So far the genetic basis and inheritance pattern of this disease are not clear.Progress in this field are reviewed here.

Objective To investigate the relationship between relevant obstetrical factors and postnatal stress urinary incontinence. Methods Standard questionnaire on international urinary incontinence was applied, which was recommended by International Continence Society(ICS). Seven hundred and eighteen primiparas from the Obstetrical Department of Hebei United University Affiliated Hospital and Qinhuangdao Maternity and Child Care Hospital were randomly selected as our subject and fill out the survey. Six hundred and seventy-three primiparas were re-examined after delivery. Their postnatal situation of urinary incontinence after 42 days was recorded. Results ( 1 )Forty-one( 6. 09% ) primiparas of 673 primiparas were diagnosed with urinary incontinence after 42 days of their parturition. There were relationship between postnatal urinary incontinence with the mode of delivery,fetus body weight,progestational body weight and body mass index,and anal contraction movements(P < 0. 05).(2)The probability of the vaginal delivery group was 7. 76%(34 / 438), higher than that in primiparas with selective cesarean section group(2. 97%(7 / 235);χ2 = 6. 1;P < 0. 05).(3) The postnatal urinary incontinence in vaginal delivery group was closely related with fetus body weight, progestational body weight,body mass index( t = 4. 316,2. 093,2. 654;P < 0. 05). Conclusion (1)The postnatal urinary incontinence is more easily appeared in vaginal delivery.(2)Progestational primiparas with light body weight,fetus with less body weight,and anal contraction movements conducted in the postpartum period,can reduce the probability of postnatal urinary incontinence.(3)Mild urinary incontinence is more likely appeared during pregnancy and in the postpartum period. Therefore,more pelvic floor muscle exercise will have a better effect on preventing and curing postnatal urinary incontinence.

Objective To explore the therapeutic effects of Montelukast for bronchial asthma combined with allergic rhinitis(AR) in children.Methods Ninety asthmatic children with AR rhinitis were randomly divided into group A,group B and control group.The children in control group were treated only with Symbicort Turbuhaler.In addition to inhalation of Symbicort Turbuhaler,the children in group A were given Montelukast 5 mg/d orally,while the children in group B were given Budesonide Nasal Spray 64 ?g/d.All the children were observed for 6 months.Daytime and night asthma symptom scores,rhinitis symptom scores,the number of days with or without acute asthma symptoms were recorded every 4 weeks.FEV1%,as one of the lung function parameters,was also recorded in the pre-treatment and 8th week,24th week after the treatment.Results After the treatment,the daytime and night asthma symptom scores and rhinitis symptom scores of group A and group B were significantly reduced(group A:F=3.45,3.35 Pa0.05).However,there was better improvement of FEV1%,more days without symptoms and fewer acute asthma attacks in group A than those in group B (t=3.83,3.76,4.26 Pa

Objective To study the changes of learning-memory ability and synapse of hippocampus after radiation injuries. Methods Sprague-Dawley rats were grouped according to radiation dose to 20Gy group,30Gy group radiated by linear accelerator and control group were used before radiation and 120 days after radiation. Morris maze test were taken to study the learning and memory ability of rats in each group. Average escape latency and search strategy were scaled and analyzed in each group. The parameters of synapse in CA3 area of hippocampus were studied by using electron microscope and image analyzer. Results AEL of 20Gy group was (41. 17 ±10.76 ) s and score of SS was 27.13 ± 2.34 after 120 days' radiation but AEL of 30 Gy group was (78.49 ± 9.32)s and the score of SS was (23.19 ± 7.65 ) nm. There were significant statistic differences Compared with control group and before radiation (P ＜ 0.05 ). The thickness of PSD of 20 Gy group was ( 22.03 ± 6.84 ) nm after 120days' radiation and (23.19 ± 7.65 )nm in 30 Gy group. There were significant statistic differences compared with control group and before radiation. It was observed that both in 20 Gy and 30 Gy group' s the length of synaptic activity area was shorter,the curvature of synaptic interface was smaller,the width of synaptic cleft and the thickness of PSD was narrower than that of control group. Conclusion There was close relation between the changes of learning-memory ability and synapse of hippocampus after radiation injuries.

Objective To discuss the clinical significance of internal fixation through anterolaterel and posteromedial approaches in the treatment of closed sagittal Pilon fractures of Topliss classification and compare the effects of the two approaches.Methods The study involved 57 patients with closed sagittal Pilon fractures treated with open reduction and internal fixation from 2007 to 2010,including 29 patients treated through anterolateral approach (Group A) and 28 through posteromedial approach (Group B).All patients were with closed fractures,and all surgery time windows were 10-19 days.The two groups were compared in aspects of gender,age,type of fractures,soft tissue graduation,injury factors,condition of combined fibula fracture,surgery time window,operation time,intra-operative blood loss,ambulation time,infection and necrosis rate of skin and soft tissue,length of stay,ankle joint function recovery after internal fixation,and intra-operative X-ray reduction.Results All patients were followed up for 12-26 months (mean,20 months) except for one patient in the Group A,with total follow-up rate of 98％.The two groups showed no significant differences regarding the gender,age,type of fractures,soft tissue graduation,injury factors,condition of combined fibula fracture,surgery time window selection,operation time,intra-operative blood loss,and ambulation time (P ＞0.05).While,the infection and necrosis incidence of skin and soft tissue,and the hospital stay we re significantly lower and shorter in the Group A than that in the Group B (P ＜ 0.05 ).Two patients in the Group A were complicated with toe extensor tendon adhesion,which was released by removing the fixation.Fifteen patients had wound infection during hospitalization,including three patients in the Group A and 12 in the Group B,but they were all cured after treatments like dressing.Fifteen patients were treated with stage Ⅰ allogeneic bone graft and 11 with autologous iliac bone graft.All the patients obtained bone union.Conclusions Topliss classification of closed sagittal Pilon fractures has clear clinical significance in surgical plan selection and operative procedures.Both of the anterolateral and posteromedial approaches can achieve good effects in the treatment of closed sagittal Pilon fractures due to high energy injury.However,the anterolateral approach is relatively a better choice,for it brings in a lower incidence of infection and necrosis of skin and soft tissue and a shorter length of hospital stay.

Objective To study the roles of AADC gene therapy for Parkinson’s disease and its action by coadministrating exogenous L dopa and discuss the effectiveness by way of cationic liposome mediated gene transferring into the brain Methods Injecting either the pCDNA3 AADC Liposome or pCDNA3 Liposome complexes into the striatum of Parkinsonian SD rats in experimental and control groups respectively, observing their improvements of rotational behavior, and furthermore, observing the improvement after combining with administration of exogenous L dopa were carried out The expression of AADC were assayed by using immunohistochemical staining Results (1) Intracerebral transplantation of pCDNA3 AADC Liposome complex improved the rotational behavior of Parkinsonian rats in some degree when its being observed at 3,7,14,21 and 28 days( P 0 05), the maximum improvement was at the time of 1 week (2) After coadministration of exogenous L dopa (10 mg/kg weight) per days, the experimental groups reached much more obvious improvement than that in the controls at the same time described above( P 0 05) (3) Immunohistochemical staining showed that the AADC were expressed stably in the striatum Conclusions Increase of AADC gene expression in the brain may improve the rotational behavior of Parkinsonian rats as well as elevate the curative effect of exogenous L dopa therapy, suggesting that it should be helpful to maintain a long term L dopa theraputic effect at a much lower level and avoid all kinds of side effects The technic of intracerebral gene transfer mediated by cationic liposome might be a new method for gene therapy of PD

AlM: To explore the clinical therapeutic effect of the integrated traditional Chinese and Western medicine treatment of idiopathic panuveitis.
METHODS: Totally 47 patients ( 69 eyes ) with the idiopathic panuveitis were included in this study, which were randomly divided into control group and treatment group. Twenty-four cases (33 eyes) with the method of Western medicine-glucocorticoid and mydriatic were in control group, while 23 cases (36 eyes) with integrated traditional Chinese and Western medicine were in treatment group. Those patients were followed up 12-36mo, the vision before and after treatment, the therapeutic effects, the complications and the side effects of glucocorticoid were recorded.
RESULTS: Both of two groups' vision after treatment were improved, but the vision of treatment group was better than the control group. The effective rate and the cure rate of the treatment group were increased significantly. Of all of the complications, the incidence rate of complicated cataract and secondary glaucoma of the treatment group were reduced significantly. Of all of the side effects of glucocorticoid, the central excitation, hypertension and central obesity of the treatment group were reduced significantly (P<0. 05).
CONCLUSlON: Dialectical therapy of integrated traditional Chinese and Western medicine has better therapeutic effect than simple Western medicine treatment of idiopathic panuveitis, and could better reduce the side effect of glucocorticoid long-term use. lt is worthy applying in clinical practice.

Aim To observe the effects of cytokine signaling inhibition protein-3(SOCS3) on the liver fibrosis progression and reverse.Methods C57BL/6 mouse model was established by subcutaneous injection of carbon tetrachloride(CCl4).After a successful model of fibrosis, one-month normal diet was given to induce the reverse fibrosis model, while normal mice of the same gender and weight were as control group.Mice were sacrificed at 1, 2, 3, 4, 5, 6, 7, 8 weeks, respectively, then the liver tissue was harvested for the observation of its injury by hematoxylin and eosin(HE) staining.Then Masson staining was applied for the detection of changes in collagen, and the immunohistochemistry(IHC) for the observation of type Ⅰ Collagen(Colla-1), alpha smooth muscle actin(α-SMA), transforming growth factor beta 1(TGF-β1) and SOCS3 protein expression.In vitro formation of fibrosis was induced by TGF-β1 stimulating HSC-T6 cell lines, which was then reversed by MDI medium, with co-incubation of HSC-T6 cells with plasmid in the process of the reverse.Western blot was employed to detect SOCS3, Colla-1, α-SMA, TGF-β1 expression.Results The expression of SOCS3 and TGF-β1 increased in mouse model of fibrosis with the worsening fibrosis process and decreased in the reverse process.Over-expression SOCS3 in the reverse process reduced the development of liver fibrosis;meanwhile, the expression of TGF-β1 was also reduced accordingly.Conclusion SOCS3 may influence the development of the liver fibrosis and its reverse via regulating the expression of TGF-β1.

Osteoarthritis (OA) is the main reason of joint pain and dysfunction in the elderly in China, and its incidence is increasing year by year. In addition to the joint peripheral osteophyte formation and degeneration of articular cartilage, in?flammation, as one of the dominant pathological changes in OA, is causing more and more attention. Pro-inflammatory cyto?kines (PIC) are important mediators of inflammation. The increased level of PIC in OA can lead to systemic and local inflam?mation, results in further destruction of many kinds of tissues in joint (such as cartilage), and accelerates the development of OA. Besides, the severity of inflammation is closely related to the clinical symptoms of OA. Therefore, it is important to un?derstand the role of PIC in the pathogenesis of OA. From the perspective of the relationship between pro-inflammatory fac?tors and OA and the molecular mechanism, this article reviews the research progress in this field, which provides new con?cepts for diagnose and treatment of OA.
