[ ABSTRACT] AIM:To explore the effect of renal transporter glucose transporter 9 ( Glu9 ) on hyperuricemia in the rats induced by fructose.METHODS:SD male rats (n=30) were randomly divided into normal group, model group and benzbromarone group , according to the weight .The rats in normal group was given water , while the rats in model group and benzbromarone group were given 10%fructose solution to establish hyperuricemia model .At the same time , the rats in normal group and model group were given a gavage of distilled water , while the rats in benzbromarone group were given benzbromarone at the dose of 20 mg/kg.The rats were sacrificed on the 40th day.The serum uric acid (SUA) and urinary uric acid (UUA) were detected to calculate the clearance rate of uric acid (CUA) in the kidney.The activity of hepatic xanthine oxidase ( XOD) was also measured .The expression of renal Glut 9 at mRNA and protein levels was determined by RT-qPCR and immunohistochemical staining .RESULTS:From the 20th day to the 40th day, the SUA in model group was significantly higher than that in normal group , but the UUA and CUA had no difference .On the 20th day, the SUA in benzbromarone group was markedly decreased as compared with model group , but UUA and CUA had no significant differ-ence.On the 40th day, the hepatic XOD activity in model group was significantly elevated , and no difference of XOD be-tween model group and the benzbromarone group was observed .Compared with normal group , the protein expression of Glut9 in the renal tissues of model group were markedly increased , and that in benzbromarone group was significantly lower than that in model group .However, no difference of the Glut9 mRNA expression was observed among groups .CONCLU-SION:Fructose drinking induces hyperuricemia in rats , which is probably related to the up-regulation of renal Glut9 ex-pression at protein level , and the increase in the reabsorption of uric acid in the kidneys .

Objective To explore the normal range of serum uric acid in quails.Method The data were collect-ed from male and female quails of different strains in 11 experiments, and analyzed by the way of medical reference value. Result The mean value of serum uric acid of male Difake strain quails was (221.06 ±79.59)μmol/L,and the normal range was (87.32 to 382.34)μmol/L.The mean value of serum uric acid of female Difake strain quails was (189.85 ± 68.58)μmol/L, and the normal range was ( 72.72 to 369.73 )μmol/L.The mean value of serum uric acid of male Longcheng strain quails was (217.22 ±72.91)μmol/L,and the normal range was (82.92 to 360.24)μmol/L.The mean value of serum uric acid of female Longcheng strain quails was ( 197.27 ±66.84 )μmol/L, and the normal range was (95.36 to 348.73)μmol/L.The serum uric acid value of female quails was significantly lower than that of male quails. There was no significant difference in the value of serum uric acid between female and male quails from each day-age groups.Conclusions This study has established the normal ranges for serum uric acid in quails of different strains and genders.

Objective To understand the status of soil?transmitted nematode infections in Xiding Township,Menghai Coun?ty,Yunnan Province,so as to provide the reference for formulating the strategy of soil?transmitted nematodosis control. Meth?ods Soil?transmitted nematode eggs in feces were detected by the Kato?Katz method,and the eggs of Enterobius vermicularis were detected by the cellophane tape method in children. The soil samples were collected from vegetable ,fruit and other crop fields of 15 residents randomly to detect hookworm. Results The stool samples from 1 002 residents were examined and the soil?transmitted nematode infection rate was 20.06%(201/1 002). The infection rates of hookworm,Ascaris lumbricoides and Trichu?ris trichura were 18.96%(190 cases),1.70%(17 cases)and 0.90%(9 cases)respectively. The percentages of people with light infection of hookworm,A. lumbricoides and T. trichura were 97.37%(185/190),88.24%(15/17)and 100%(9/9)respec?tively. No infection of E. vermicularis was found. Fifteen soil samples were tested,and no hookworm was found in the soil. Con?clusion The infection rate of soil?transmitted nematode in Xiding Township,Menghai County is high,but the infectiosity is light. The control and monitoring of soil?transmitted nematodosis should be strengthened in this area.

ABSTRACT:In recent years ,there has been high prevalence of murine typhus in Yunnan Province ,People's Republic of China .A large outbreak of murine typhus occurred in Xishuangbanna Prefecture ,Yunnan Province in 2010 .However ,not all cases were confirmed by laboratory assays ;therefore ,field epidemiologic and laboratory investigations of murine typhus in Xishuangbanna Prefecture were conducted in 2011 .Blood samples were collected from clinical diagnostic cases at the acute and convalescence stages of murine typhus in Xishuangbanna Prefecture ,Yunnan Province ,from June to September of 2011 ,and blood and spleen samples were collected from mice sharing the same habitats as the patients .Immunofluorescence assays were used to test for the presence of IgM and IgG antibodies against Rickettsia typhi in sera from patients and mice .Real‐time PCR was used to detect the groEL gene of R .typhi in blood clots from patients at the acute stage and in spleen tissue from mice .A total of 1 157 clinically diagnosed murine typhus cases occurred in Xishuangbanna Prefecture ,Yunnan Province in 2011 ,with an incidence of 102 .10/100 000 .Of these cases ,80 were investigated by laboratory assays and 74 of 80 patients were confirmed to have murine typhus .The coincidence rate between the clinical diagnosis and laboratory detection was 92 .50% .The positivi‐ty rate for IgG antibodies against R .typhi was 14 .0% (14/100) for Rattus f lavipectus ,while the rate by PCR was 9 .0%(9/100) .That laboratory diagnoses confirmed that the severity of the murine typhus outbreak in Xishuangbanna cannot be ig‐nored .The distribution of host animals transmitting R .typhi underscores this conclusion .

Objective: To explore experience of wound treatment of extremely severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident. Methods: On August 2nd, 2014, 98 extremely severe burn mass patients involved in August 2nd Kunshan factory aluminum dust explosion accident were admitted to 20 hospitals in China. The patients with complete medical record were enrolled in the study and divided into microskin graft group with 56 patients and Meek skin graft group with 42 patients. Split-thickness skin in area of residual skin were resected to repair wounds of patients in microskin graft group and Meek skin graft group by microskin grafting and Meek miniature skin grafting, respectively. The residual wound size on 28 days post injury and wound infection after skin grafting of patients in the two groups, and position of donor site of all patients were retrospectively analyzed. Data were processed with t test and chi-square test. Results: The size of residual wound of patients in Meek skin graft group on 28 days post injury was (59±13)% total body surface area (TBSA), which was obviously smaller than that in microskin graft group [(70±14)%TBSA, t=4.379, P<0.05]. Twenty-nine patients in microskin graft group and 11 patients in Meek skin graft group suffered from obvious wound infection after skin grafting. Wounds of patients in two groups were repaired with residual skin around wound in head, trunk, groin, armpit, and uncommon donor sites of scrotum (4 patients), vola (10 patients), and toe or finger web (8 patients). Conclusions Meek skin graft is the first choice for wound repair of extremely severe burn mass patients, with faster wound healing, less wound infection. Uncommon donor sites of scrotum, vola, and toe or finger web can also be used for wound repair in case of lack of skin.
