Recent studies show that vitamin D plays a role in lung development and regulation of lung maturation in the fetus. The AAP and the Institute of Medicine( IOM) both define vitamin D insufficiency as ser-um 25-OH-D concentrations <50 nmol/L in the pediatric population. The surveys in our country show the prev-alence of vitamin D insufficiency is higher according to the criteria defined by AAP. Evidence from animal study suggests that vitamin D may increase alveolar count,alveolar septal thickness,lung volume and decrease airway resistance,immune cell aggregation leading to the maturation of lung. The cohort studies suggest low 25-OH-D level in infants at birth is associated with greater need for assisted ventilation,increased rate of ARDS,increased duration of oxygen requirement.

[Objective] To investigate the clinical efficacy of tacalcitol combined Halometasone sequential therapy in the patients of plaque psoriasis. [Methods] 117 cases of plaque psoriasis col ected between 2011.01 and 2013.02 were randomly divided into treatment group and control group. The treatment group were treated with tacalcitol and Halometasone therapy, and required topical use Halometasone(1 time/day) in the morning ,tacalcitol use in the evening(1 time/day) before the first 2 weeks. Continuous two weeks treatment from Monday to Friday with tacalcitol(2 times/day), Saturday and Sunday with Halometasone(2 times/day), final y the transition to be used alone tacalcitol(2 times/day) in the next two weeks of continuous treatment. Control group of pa-tients given alone Halometasone(2 times/day) for 6 consecutive weeks. Observe the adverse reactions PASI scores during and after completion of treatment within the two groups. Al patients were fol owed for three months, observed recurrence. [Results] The PASI score between two groups of patients declined during treatment, especial y at the 4th and 6th week within the treatment group. Both groups had no serious adverse reactions. In treatment group, 54 patients had effective responses, the total effective rate was 90%, significantly better than the control group(41 cases,71.9%). In the fol ow-up of 3 months, the recur-rence rate was 11.1%in the treatment group, significantly lower than the control group(31.6%). The difference of total efficiency and the recurrence rate with-in the two groups was statistical y significant. [Conclusion] Tacalcitol combined Halometasone sequential therapy of plaque psoriasis has significant clinical effi-cacy and low recurrence rate.

A high dose E. Coli endotoxin was infused into unanesthetized sheep withchronic lung lymph fistula. The contents of substance P in plasma, lung lymph, lungparenchyma and also TXB_2 and 6-keto-PGF_1? were measured. The results showed that 120min after infusion substance P increased in plasma and lymph, but its content in paren-chyma decreased at 360 min after infusion. At 30 min after infusion, TXB_2 and 6-keto-PGF_1? levels in plasma showed a marked increase, but their peak values in lung lymphwere shown at 60 min after infusion, and the levels of TXB_2 were much higher than thatof 6--keto--PGF_1?

Scleredema is a rare skin disease of unknown cause involving the face, neck, upper portion of the trunk, and proximal upper extremities. The clinical features of it are nonpitting, solid emema or stiffness of the neck, which may be sudden or insidious onset. Preceeding upper respiratory infection or diabetes mellitus have been frequently discribed to be associated with the disease. A monoclonal gammopathy has been frequently observed in patients with scleredema. We present a case of scleredema developed the face, upper portion of the back and shoulder in 16-year-old girl who had a preceeding upper respiratory infection.

Objective: To observe the effects of Thermafil obturat ion technique.Methods: 60 premolars with pulp pathema or periapical dese ase were divided into two groups with 30 in each at random,The teeth were treate d and the root canals were obturated by Thermafil obturation technique and later al condensation technique respectively. Preoperative and postoperative radiograp hs of each tooth were taken. Obturation time, incidence of pain during obturatio n and quality of obturation were compared.Results: Overfi lling was found in 11 cases in Thermafil group,while 3 in lateral condensation group( P 0.05).The average obturation tim e per canal of Thermafil and lateral condensation technique was 36.6 s and 247 .4 s respectuively ( P

Objective To study the construction of tissue engineering adipose in vitro with silk fibroin scaffold and human umbilical cord mesenchymal stem cells (hUCMSCs) transfected by recombinant human insulin gene lentivirus.Methods hUCMSCs infected with recombinant lentiviral pLenti6.3-insulin-IRES-EGFP (Group A) by the best MOI=10 were seeded in silk fibroin scaffold; hUCMSCs transfected by EGFP gene (Group B)was regarded as negative control; and then the cell-scaf-fold complexes were cultured in adipogenic differentiation medium. MTT test was used to detect whether recombinant lentiviral affected the growth and proliferation of hUCMSCs and the growth activity of hUCMSCs seeded in silk fibroin.Results After 5-7 days for adipogenic culture,the numbers of fat-like cells in group A were significantly more than those in group B (P =0.007,P＜0.01).RTPCR results showed that the expression of PPARγ-2 in group A was much stronger than that in group B.MTT test showed that there was no significant difference in optical density (A)at each time between transfected group and nontransfected group (P=0.056,P＞0.05).And there was also no significant difference in optical density (A)between cell group and cell-scaffold group (P =0.066,P＞0.05).Conclusions Insulin gene could obviously promote hUCMSCs getting into adipose,and carrying recombinant human insulin gene lentiviral vector transfection of hUCMSCs and silk fibroin scaffolds could effectively construct tissue engineering adipose in vitro.

Objective To investigate the clinical significance of laparoscopic operations in gynecologic emergency. Methods We retrospectively analyzed 145 cases of gynecologic emergency dealt with laparoscopic operations in May 1997～August 2001. Out of the 145 cases, tubal pregnancy accounted for 100 cases (Laparoscopy Group), which were further compared with 89 cases of tubal pregnancy in January 1994～April 1997 treated by open operations (Open Group). Results Out of the 145 operations, 139 (95.9%) were successfully carried out under laparoscope, with the conversion to open operations in 6 cases. There were 61 cases of salpingectomy, 28 cases of oviduct fenestration, 11 of fenestration converting into salpingectomy, 16 of partial ovariectomy, 8 of adnexectomy for ovarian cyst pediculotorsion, 4 of cyst resection, 3 for rupture of endometrial cyst of ovary, 6 for pelvic abscess and 2 for pelvic encapsulated fluid. Compared with the Open Group, the Laparoscopy Group had longer length of surgical intervention (t=3.9, P=0.000) and more intraoperative blood loss (t=5.8, P=0.000). Conclusions Laparoscopic operations play double actions both in diagnosis and in treatment for most gynecologic emergencies, being a safe and reliable approach. Laparoscopic salpingectomy (non-oviduct-sparing operations), however, should be chosen for urgent patients.
