Objective To evaluate the control effect of comprehensive measures of schistosomiasis after its transmission in?terruption in Kaihua County,Zhejiang Province,so as to provide the references for further consolidation of schistosomiasis con?trol. Methods The data of Oncomelania hupensis snail survey and control,as well as environmental reform in Kaihua County were collected and analyzed from 1996 to 2015. Results From 1996 to 2015,totally 2 635 snail habitats and 102.75 hm2 area with snails were found,and 125.4 thousand snails were dissected and no one was schistosome infected. The accumulated snail control area was 4 932.98 hm2,and the area with snails was effectively reduced by the comprehensive control measures. Conclu?sion The schistosomiasis control effect could be consolidated by the comprehensive control measures emphasizing environmen?tal reconstruction,and the snail surveillance work still should be strengthened.

Objective To evaluate the effect of triamcinolone orbital injection combined with dexamethasone in treatment of the patients with the grade Ⅳ of thyriod associated ophthalmopathy. Methods NOSPEVS Ⅳ grade of 90 patients were randomly divided into three groups,Group A,orbital injection of triamcinolone combind with dexamethasone, Croup B,simple injection of triamcinolone,Group C,oral prednisone therapy for half a year. To review each record of visual acuity intraocular pressure palpebral fissure size, upper eyelid drop late exophthalmos eye movement and so on every 4 weeks and follow-up for one year. Results Group A and group B of exophthalmos and eye movement improved obviously,however,Group C with poor efficacy and more side effects,and Group A in 3 groups was the fastest with least number of injections and which improved eye symptons significantly with fewer complications. Conclusion Orbital injection of triamcinolone combined with dexamethasone could be more rapid and effective than a simple injection of triamcinolone or oral prednisone to improve symptoms and signs in thyroid ophthalmopathy.

Objective To evaluate the relationship of diurnal variation of antidiuretic hormone (ADH) with urinary output,serum osmolality and blood pressure in spinal cord injury (SCI) patients. MethodsThe study was prospective,random and contrastive. Twenty complete SCI patients (two females and 18 males,Complete SCI group) and ten healthy controls (two females and eight males,control group) were studied. Urinary output and osmolality in the day time (8:00-20:00) and at night (20:00-8:00) were recorded. Blood samples for the measurement of serum osmolality and ADH were drawn at 14:00 and 2:00. Results There was very significant difference in regard of urinary output between day time and night time in complete SCI Group and control Group ( P 0.05). However,ADH level increased in the healthy Group at night,with a very significant difference ( P

In a fusion of BABL/C murine spleen cells immunizated with human fetal thymocytes and P_3X_(3)Ag_(,3), myeloma cells, six monoclonal antibodies(McAb) were produced. They were termed HIT_1. HIT_2. HIT_3. HIT_4.HIT_(6-1) and HIT_(6-2), respectively. The specificity of these McAbs were analysed by indirect immunofluorescence technique and FACS.Results showed that they reacted with 80～90%thymocytes,but hardly with peripheral blood mononuclear cells and spleen cells in adults,and nonreactive with red blood cells, granulocytes and platelets, According to their reaction with the tonsil cells, we can divide these six McAbs into three groups: Groupl including HIT_1, HIT_2, and HIT_(?) McAbs reacted approximately with 1/3 tonsil cells; basically GroupⅡ including HIT_(6-1) and HIT_(6-2) McAbs gave negative reaction with tonsil cells; GroupⅢ McAb HIT_4 reacted with 15% tonsil cells, which suggested these were a heterogeneous group McAbs with different specificities. In comparision with OKT series of McAbs in thymus, peripheral blood and tonsil, HIT_(1-3) are similar to OKT_(10) and,HTT6-l and HIT_(6-2) are just like OKT_6,but HIT_4 seems to be a new McAb different frOm HIT_(1-3) and HIT_(6-1) HII_(6-2). The competitive binding assay showed that HIT_(6-1) and HIT_(6-2) labeled with FITC can be inhibited by unlabeled HIT_(6-1) and HIT_(6-2) each other and can also be blocked by OKT_6, suggesting further these antibodies recognized a same epitope on thymocytes. Cross reaction were also demonstrated on HIT_1, and HIT_2 but not on HIT_3, suggesting HIT_1 and HIT_2 recognized the same determinant and HIT_3 recognized another. So six antibodies are McAbs against T cell differentiation antigens.They are useful for research the differentiation of T cells and the classification of malignant lymphadenosis diseases.

Objective To fabricate an antibacterial controlled drug delivery system with PEG-hydrogel and gentamicin-loaded-CSt on titanium surface,and to investigate its surface characteristics,swelling behavior,drug release behavior in vitro,antiinfection performance in vivo,and tissue biocompatibility.Methods Cross-linked starch (CSt) was synthesized first and then CSt was loaded with gentamicin (GEN) as a carrier (GEN@CSt),then 4-arm-polyethylene glycol (PEG) was added to it which was mixed by ultrasound.The surface of titanium (Ti) was covered with a layer of poly dopamine (PDA).The drug-loaded hydrogel was fixed to the titanium surface,subsequently capped by poly lactic-co-glycolic acid (PLGA) membranes,and then the Ti-PDA-PEG (GEN@CSt)-PLGA composite coating was fabricated finally.Surface morphology of the system was observed,while the swelling behavior was characterized;release behavior of the composite coating was detected;the bacteriostatic experiments were carried out with staphylococcus aureus (SAU),staphylococcus epidermidis (SEP) and escherichia coli (ECO) in vitro.The animal models of infected bone defect was established in 36 New Zealand white rabbits.These animals were randomly divided into three groups.Group 1 animals were implanted with drug-loaded composite coatings.Group 2 animals were implanted with drug-free composite coatings.Group 3 animals were implanted with bare titanium rods.The infection data were collected periodically to carry out antiinfection experiments in vivo.Another 12 rabbits were divided into the experimental group and the control group randomly.Biocompatibility of the materials was observed by histopathology after implantation of the corresponding materials into the femoral condyle.Results The composite coating adhered to the titanium surface firmly,presenting a smooth and translucent shape.The ratio of CSt/PEG affects swelling behavior varied,starch-free gels maintained an equilibrium swelling of 7.4,after the ratio reached 1 ∶ 1,the equilibrium swelling ratio remained at 3.0.In-vitro the release rate of the first 8 h was fast,and the cumulative release amount accounted for 83％ of the total in the first 7 days,lasting more than 13 d.In vitro antibacterial test,the average diameter of the inhibition ring was 3.6±0.13 cm (SAU),3.4±0.11 cm (SEP),3.7±0.10 cm (ECO).In-vivo anti-infection experiment,the infection situation of the group 1 was better than the control groups 2 and 3.The pathological results indicated that inflammatory reaction in the experimental group was basically the same as the control group.Conclusion The study successfully fabricated the antibacterial controlled drug delivery system with PEG-hydrogel and gentamicin-loaded-CSt on titanium surface.The system has a reasonable drug release behavior,and effectively inhibited the growth of bacteria in vivo and in vitro.It also has good biocompatibility to stand a promising strategy to improve the orthopedics anti-infection.
