Objective To study the clinical features of children with rotavirus enteritis complicated with respiratory infection.Methods The clinical features of 32 children with rotavirus enteritis were evaluated retrospectively complicated with respiratory infection (respiratory infection group) and 37 children with rotavirus enteritis complicated without parenteral infection (control group).Results 1. The respiratory symptoms became alleviative as the alimentary symptoms changed for better. 2. Duration of diarrhea weve(7.06?1.50)d in respiratory group was significantly longer than that in control group (4.73?1.31)d (t=6.90 P

Objective To study the effect of topical tacrolimus (FK506) on the survival of the xenogeneic transplanted hair follicles from human scalp to Wistar rats. Methods In our study, Wistar rats were used as recipients and human as donor. The black hair follicles of human scalp were harvested, and then the xenogeneic grafts were transplanted to white Wistar rats on the back. 20 couples of rats were divided in 2 groups: topical tacrolimus group (group A), and blank control group (group B). After operaton, we compared the survival time of hair follicles and their histologic outcomes in order to verify the practicability of xenogeneic transplantion of hair follicles, and the topical application of tacrolimus results.Results The mean survival time of group A was longer [(49. 9 ±7. 1) days] as compared to group B [(13. 1±1. 2) days]. The longest survival time was 65 days in group A and 14 days in group B, respectively. By comparison of the results we found that topical tacrolimus prolonged the survival time of the xenotransplanted hair follicles significantly and that tropical medication could not avoid rejection. Conclusions The immune privilege function dependent on the hair follicle anagen and axillary topical tacrolimus, can prolong the survival time of the xenogeneic transplanted hair follicles in rats significantly.

Objective To investigate the effect of Mepilex on pressure sores in patients at lateral position after craniocerebral surgery.Methods Toally 60 patients lying at lateral position after craniocerebral surgery were randomized into two groups in equal number with random digit table:the control group and experiment group.In the control group,Gel pad was used to prevent and treat the pressure sores and in the experiment group Mepilex was used between the compressed skin and operation table before setting the position.The skin conditions of the two groups were observed after operation.Result The prophylactic effect of pressure sore in the experiment group was significantly better than that in the control group (P＜0.05).Conclusion Mepilex can prevent the skin pressure sores in the patients at lateral position after cerebral surgery.

OBJECTIVETo record the electrical activities of Antirior cingulate cortex (ACC) neurons by in vivo multi-channel recording methods using the model of complete freund's adjuvant (CFA) induced conditioned place avoidance (C-CPA), which has been set up in our previous studies.

METHODSThe electrode was self-made and the CPA responses were recorded by in vivo multi-channel recording method.

RESULTS(1) The electrical activities of ACC neurons could be successfully recorded by the self-made electrode. (2) Before or after the injection of CFA, rats were respectively conditioned to the different place. The firing rates of ACC neurons in the CFA-paired place vs that in the non-CFA-paired place was (0.853 ± 1.377) imp/s vs (0.221 ± 0.971) imp/s (P < 0.05, n = 26). (3) The CPA responses in the CFA-paired place vs that in the non-CFA-paired place were (303.55 ± 61.77)s vs (140.32 ± 33.52)s(P < 0.05, n = 6).

CONCLUSIONThe firing rates of rACC (rostral Anterior Cingulate Cortex) neurons were involved in the occurrence of the affective pain.

According to morphological and microscopic characteristics, a high-efficient decolorizing fungus, the strain Asaw117, was identified as Aspergillus awamori. Selecting eight different dyes from Azo dyes, anthraquinones dyes and oxygen Quinones dyes, the decolorizing assays of various dyes showed that the strain Asaw 117 was the highest decolorizing potential to 0.1 g/L Vat Blue RSN, the discoloration rate up to 100 percent. Comparing to different kinds of medium and several of carbon and nitrogen sources, the strain had the best decolorizing efficient although grew slower in the Czapek medium, otherwise, grew quicker and decolorizing efficient lower in the PDF medium. It could use Vat Blue RSN as a nitrogen source, but not as a carbon source. The medium composing of saccharose and ammonium nitrate as carbon and nitrogen sources was decolorizing potential markedly during different combinations of carbon and nitrogen sources. So the strain has good potential for the dyeing wastewater treatment

Objective The autoantibodies against angiotensin Ⅱ type 1 receptor(AT_1 RAb)have been dis- covered in the patients with malignant hypertensive and preeclampsia,this autoantiboies(AT_1-AA)have an ago- nist-like activity effect similar to angiotensin Ⅱ(Ang Ⅱ).This study aimed at investigation the effect of Ang Ⅱ agonist-like activity by AT_1-AA on VSMCs proliferation was obtained from essential hypertensive patients. Methods VSMCs were cultured from aorta of WKY rats.The hypertensive patients" serum was purified by am- monium sulfate precipitation and affinity chromatography.The effect on VSMC proliferation this autoantilody was determined by BrdU incorporation.Total protein and the expression of phosphorylation JAK-STAT were assessed by Western blotting.Results AT_1RAb caused a significant increase in BrdU incorporation similar to Ang Ⅱ during 0-24 h reaching peak value at 12 h.The A value of in 450 nm was higher in AT_1RAb group (0.236?0.012)than AG490+AT_1RAb group(0.176?0.009),Losartan+AT_1RAb groups(0.119?0.006) and Serum Free group(0.127?0.006)(P

?AIM:To compare the changes of the contrast sensitivity after LASIK with femtosecond laser and microkeratome and to explore the influence of different methods making corneal flap on visual quality.? METHODS: There were 212 eyes in 106 myopes underwent excimer operation . According to the different methods of operation, they were divided into two groups:microkeratome group ( SBK group ) and femtosecond laser group ( FS group) . FS group: a total of 112 eyes in 56 patients received LASIK with femtosecond laser. SBK group: a total of 100 eyes in 50 patients received LASIK with microkeratome. Contrast sensitivity was detected preoperatively, and 1wk, 3mo postoperatively and compared between the two groups.? RESULTS: At 1wk after operation, the contrast sensitivity under photopic environment decreased in the two groups, compared with those before operation ( P<0. 05). The differences of contrast sensitivity before and 3mo after operation were not significant (P>0. 05). No statistical significant difference was found in contrast sensitivity under photopic environment at 1wk, 3mo between the two groups ( P>0. 05 ). At 1wk after the operation, the contrast sensitivity under scotopic environment decreased in both groups compared with those before operation ( P< 0. 05 ). In SBK group, it decreased more than in FS group (P<0. 05). After 3mo, the decline of 14. 2c/d spatial frequency contrast sensitivity under scotopic environment in the SBK group was more than other frequency. No statistical significant difference was found in the rest frequency contrast sensitivity under scotopic environment before and after operation (P>0. 05). After 1wk, contrast sensitivity with glare stimulation in both groups decreased, compared with those before operation ( P< 0. 05 ), while in SBK group, it decreased more than in FS group (P<0. 05). After 3mo, except that the decline of 14. 2c/d spatial frequency contrast sensitivity with glare stimulation in the SBK group was significant compared with those before operation, the contrast sensitivity under glare stimulation in both groups had no significant differences compared with before operation(P>0. 05).?CONCLUSION:LASIK with femtosecond laser can get a better visual quality than LASIK with microkeratome.

It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".
