Nutritional therapy is an important part of therapy of chronic diarrhea in children. The nutritional status is very important to growth and development of the children patients. The supplementation of appropriate amount of protein,abundant energy,vitamin,minerals and probiotics can improve the nutrition and promote growth and develop-ment,then remission the development of disease and decrease the incidence of the complication.

Mechanical stresses modulate almost all aspects of cell function, including growth, differentiation, migration, gene expression, protein synthesis and apoptosis. Thus, uncovering the mechanisms by which living cells sense and transduce mechanical stress lies at the core of understanding how they respond and adapt to their physical environments. In this review, the possible mechanism about cell response to mechanical stimulus was discussed from outer cell membrane to inner nucleus.

The serial changes in thromboxane (TXA2) prostacyclin(PGI2),circulatory platelet aggregate ratio (CPAR),platelet count,blood viscosity,myocardial enzyme spectrum,cortisol and epinephrine were determined in 42 severely burnt patients randomly divided into two groups.The findings demonstrated that in the control group,both TXA2 and TXA2/PGI2 ratio increased significantly during the early postburn stage.Myocardial enzyme spectrum,blood viscosity,cortisol and epinephrine also increased markedly.However,levels of the above parameters in the anisodamine-treated group were significantly lower than in the control following the infusion of anisodamine.On the contrary,CPAR and platelet count in the treated group increased and were significantly higher than those in the control.Moreover,TXA2 was closely correlated with CPAR,platelet count,blood viscosity and myocardial enzyme spectrum (P

Forty-one burn patients were divided into inhalation injury and non-inhalation injury groups.It was found that in the inhalation injury group,TXB2 level and TXB2/G-keto-PGF1? ratio in plasma and lung tissue were significantly elevated,circulatory platelet aggregate ratio markedly decreased,and blood viscosity greatly increased.Histopathologically,congestion,edema,hemorrhage and thrombosis were seen in lung tissue.The changes of TXB2 level and TXB2/6-keto-PGF1?ratio were parallel to the clinical course of the development of respiratory failure in the patients with body surface burns complicated with inhalation injury.It is believed that the imbalance of TXA2/PGI2 is one of the factors of respiratory failure in severe body surface burns complicated with inhalation injury.

Objective To analyze the current endemic situation of schistosomiasis and evaluate the control effects of the implementation of comprehensive management measures for 4 years,so as to provide references for making control strategy in the next stage. Methods The endemic villages were grouped into categories based on egg positive rates of fecal examinations among villagers. Praziquantel chemotherapy regimens were provided for villagers and domestic animals,respectively. Snail control on the basis of niclosamide was conducted in snail habitat areas in the hilly area and inside embankment in Dongting Lake,and in infected snail distributed areas outside the embankment in the lake. A slow releasing formation of niclosamide were applied for cercariae killing in transmission areas outside the embankment in the lake in the flood season. The modification of snail habitat areas was integrated into the water conservancy and agricultural development projects. The varied health education,safe water supply and disinfestation toilet facilities were provided for residents in the community. Results The infection rate of schistosomiasis in residents dropped by 49.88%,and the estimated patients reduced by 39.62%. Acute schistosomiasis cases significantly decreased. The total number of advanced schistosomiasis cases slightly increased. The infection rate of schistosomiasis in livestock dropped by 66.36% and snail areas reduced by 33.31% as well as no infected snails were found inside the embankment. Yet,the total areas of snail habitats and distributed areas of infected snails slightly increased,with a high density. The first scale of villages and the second scale of villages were lowered into the third or fourth scale of villages. Out of 31 endemic counties (districts,farms),7 reached the criteria of transmission control,24 reached the criteria of infection control. Conclusions The implementation of the comprehensive management measure has achieved the anticipated results of reducing the infection rate of schistosomiasis among villagers and dropping the incidence of acute schistosomiasis. Yet the snail area on beaches outside the embankment slightly increases,with a high density of infected snails and so there is an infection danger there.

Objective To explore the effect of MMP-1, TIMP-1 on burn wound healing and hypertrophic scar (HS) forming. Methods Normal human full-thickness skin grafts were transplanted to the back of nude (athymic) mice, after these grafts survived, deep Ⅱ degree burn wounds were made in the middle of these grafts. During the process of burn wound healing and HS formation, the expressions of MMP-1 and TIMP-1 were detected by immunohistochemical staining. Results MMP-1 expression was first noted by day 2 after burns and became more prominent from day 3 to day 15, and then decreased rapidly. Immunostaining for MMP-1 was markedly increased at boundary regions marked by connective tissue fluidity. Immunoreactive TIMP-1 was also detected by day 2 but rapidly assumed the same interface expression pattern as described for MMP-1. Compared with MMP-1, immunostaining of TIMP-1 was irregular, but was obvious around vascular tissues. Conclusions The balance between MMP-1 and TIMP-1 during the inflammation and granulation phases might be important for the regulation of collagen proteins degradation. Within the remodeling phase, the inhibition of MMP-1 by TIMP-1 and the decrease of collagen degradation might lead to HS forming. The striking immunolocalization of MMP-1 and TIMP-1 to epithelial-dermal, eschar-dermal, and vascular-dermal interfaces suggested that they might play a particularly significant role at boundary regions marked by connective tissue fluidity.

Objective To make out the effective method of emergency materials management. Methods According to the native regular emergency diseases and the orders of superior section make out a general method for emergency materials management. Results This general management method can effective solve the problems which have existed in the aspect of emergency materials management. Conclusion By using general management method could advance the quality of first aid.

Objective To study the dynamic change of polysaccharide from Asarum insigne in Guizhou during different harvest period and its hemostatic effect. Methods Asarum insigne polysaccharide was extracted by water isolation and alcohol precipitation. We measured the polysaccharide content by UV spectrophotometry after impurity and purification and detected the bleeding and clotting time by tail cutting and slide methods in mice. Results There was significant variation in polysaccharide content of Asarum insigne at different harvest time, which was at a higher level in June(1. 78%-1. 82%). The bleeding time in mice of normal control group was (6. 73±1. 21) min,and that in mice treated with refined polysaccharide at high dose was (4. 91±1. 58) min,the difference between two groups was statistically significant(P<0. 01). The clotting time in mice of normal control group was (7. 27±2. 09) min,and that in the refined polysaccharide at middle and high dose groups was (3. 96±1. 78) min and (3. 27±1. 61) min,respectively. The latter two groups were obviously different from the normal control group(P<0. 05 or P<0. 01). Conclusion The polysaccharide is an active hemostatic substance in Asarum insigne and the optimum harvest time of it is in June for the clinical use.

This paper introduced the position setup and initial recruitment initiated in publicfunded institutions in Beijing, i.e. Beijing Stomatological Hospital. It stated that position setup should fit actual needs and recruitment standards should comply with long-term development strategy. In addition, the paper highlighted such principles as transparency and all-staff involvement, along with the supervising function of departments and experts of the hospital. Thus, position setup and initial recruitment can be smoothly accomplished, forming a long-standing incentive for medical staff.
