This paper reports 17 cases of hypomagnesemic convulsiens of the newhorn that were admitted from Se-Ptember 1981 to January 1983. Only 2 patients were breast-fed.Symptoms and signs of hypomagnesemia are indistinguishable from these of hypocalcemia unless the serum magne-sium is determ ined. Serum magnes iumlevels had been determined in 50 normal children. The average value-2 standard deviation=2.17-2?0.34=1.49mEq/L.We defined hypomagnesemia as the serum magnesium lcvels below 1.48mEg/L. The serum magnesium levels of 17 patients varied from 0.65 to 1.46m Eq/L. Of 10 cases serum calcium le-vel6mg/dl.2.5%MgSO_4 was given intraveno-usly by continuous infusion in a dose of 2-4ml/kg every 12 hours. After the convulsions had been controlled a dose of 25% MgSO_4 was given intramuscul-arly in a dose of 0.4ml/kg twice daily Convulsions usually ceased after 1--4doses of MgSO_4, but the serum magne-sium levels did not rise to normal le-vels until 2-6 days. The convulsions could not be controlled by repeated ad-ministrations of calcium gluconate in 5 patients who had both hypomagnes-emja and hypocalcemia. Only after theadministiation of MgSO_4 did the serum calicum levels rise to the normal level and the convulsions cease.Electrocardjograms recorded in 7 patients all were abnormal but 1 case,so we should pay attention to the inf-luence of magnesium upon the heart.

OBJECTIVETo examine the effects of Han's acupoint and nerve stimulator (HANS) electroacupuncture on the expression of NPY in periaqueductal grey (PAG) of heroin addicted rats.

METHODSHeroin was injected subcutaneously according to the principle of daily increasing dose in rats of experimented group. The ability of special learning and memory were tested by Morris water maze; The expression of NPY in PAG of rat were detected by immunohistochemistry.

RESULTS(1) Escape latency and searching distance in heroin-addiction group were significantly increased compared with those of normal group during the place navigation test (P < 0.05). However, in acupuncture group, escape latency and searching distance was obviously shortened compared with those of heroin-addiction group (P < 0.05). The exploring time and distance of original platform area in proportion to the total distance in heroin-addiction group significantly decreased compared with those of normal group during spatial probe test (P < 0.05). The exploring time and distance of original platform area in proportion to the total distance in acupuncture group was increased compared with those in heroin-addiction group (P < 0.01). (2) The expression of NPY of heroin-addiction group was lower than that in normal group in PAG, while those of acupuncture group was higher than that in the heroin-addiction group (P < 0.05).

CONCLUSIONThe learning and memory induced by heroin-addiction could be reversed and the expression of NPY in PAG was increased by HANS in rats.

OBJECTIVETo identify the expression characteristics of the 1700001022RIK (RIKEN cDNA 1700001022) gene in mice and explore its function by bioinformatic analysis.

METHODSUsing the expression profile of gene microarray, we detected the expression of a new testis-specific gene, 1700001022RIK, in mice. We analyzed its expression characteristics in the testis tissue and their changes in different developmental stages of the testis by RT-PCR, real-time RT-PCR, Western blot, and immunohistochemistry. We performed bioinformatic analysis using a bioinformatic software.

RESULTSThe 1700001022RIK gene was specifically expressed in the mouse testis in an age-dependent manner, most highly in the adult mice. The 1700001022RIK protein was mainly expressed in the spermatogonia, spermatocytes, and round spermatids of the adult mice. Bioinformatic analysis showed that the 1700001022RIK protein amino acid sequence had a high similarity in human and mice, which indicated that this gene was highly conserved in mammals.

CONCLUSION1700001022RIK is a testis-specific gene mainly expressed in the spermatogonia, spermatocytes, and round spermatids of seminiferous tubules, which might be involved in the regulation of spermatogenesis.

OBJECTIVETo investigate the potential role of serum citrulline level in evaluating the intestinal absorptive area and capacity in patients with short bowel syndrome (SBS).

METHODSSerum citrulline concentration was determined using high performance liquid chromatography (HPLC) in SBS patients (n=22) and healthy controls (n=33). In SBS patients, the remnant small bowel lengths and diameters were measured by radiography, and their 5- hour urine D- xylose excretion and intestinal protein absorption were also determined. The correlationship of serum citrulline level with remnant small bowel length, surface area, protein and D- xylose absorption was analyzed. The 6 patients receiving intestinal rehabilitative therapy, serum citrulline level, protein and D- xylose absorption after therapy were also measured.

RESULTSSerum citrulline level of SBS patients was significantly lower than that of healthy controls [(5.94+/- 2.65) vs [(16.87 +/- 5.97) micromol/L, P < 0.01]. In SBS patients, serum citrulline was positively correlated with remnant small bowel length and surface area (r=0.82 and r=0.86 respectively). There was also a significant correlationship of serum citrulline level with 5- hour D- xylose excretion (r=0.56) and intestinal protein absorption (r=0.48). Serum citrulline, 5- hour D- xylose excretion and intestinal protein absorption were all significantly raised in patients after rehabilitative therapy, although no correlation of increasing percentage was found among above three parameters.

CONCLUSIONSSerum citrulline concentration is positively correlated with intestinal absorptive area and capacity in SBS patients. It is a potential marker for evaluating the severity of intestinal failure and the efficacy of rehabilitative therapy in short bowel patients.

1,3-propanediol (1,3-PD) is an important material for chemical industry, therefore, there is much interest in the production of 1,3-PD. The gene dhaT encoding 1, 3-propanediol dehydrogenase ( PDOR) of Citrobacter freundii was amplified by PCR. Sequence analysis of the similarity at the nucleotide and amino acid level between the gene encoding C. freundii PDOR and that of C. freundii ( U09771 ) were 78% and 90% , respectively. The recombinant plasmid pSE-dhaT was constructed by inserting dhaT gene into expression vector pSE380 and then transformed E. coli JM109. The recombinant strain was induced by IPTG to express dhaT. Further more the recombinant enzyme was purifed from recombinant E. coli by Ni-nitrilotriacetate affinity chromatography followed by Sephacral S-300 gel filtration. A single obvious protein about 42kDa could be obtained by the sodium dodecyl sulfate-polyacrylamide gel electrophoresis of recombinant enzyme. The purified enzyme was used to determined enzyme property on the substrate of propionaldehyde and 1, 3-PD. The optimal temperature and optimal pH of the purified enzyme were 37℃, 8.0 for reduction and 25℃, 10. 5 for oxidation, respectively; and the kinetic property of PDOR about Km and V max were 10. 05mmol/L, 37. 27?mol/min/mg for propionaldehyde and 1. 28mmol/L, 25. 55?mol/min/mg for 1,3-PD, respectively; The deduced dhaT gene product (388 amino acids) showed a specific reduction activity of 49. 50U/mg and oxidation activity of 79. 92U/ mg. There also have a putative iron-binding motif ( G-XX-H-X-X-A-H-X-X-G-X-X-X-X-X-P-H-G) as a fingerprint pattern in the recombinant enzyme, the motif is fully conserved among these 1, 3-propanediol dehydrogenase. It is beneficial to the researches of high producing 1, 3-propanediol by gene engineering strain.

OBJECTIVETo explore the effect of temperature dropping process in cold air on the coagulation function both in healthy and hypertensive rats.

METHODSTwenty-four male healthy Wistar rats and 24 male spontaneous hypertensive rats (SHR) were randomly divided into the minimum temperature group (Tim), Tmin control group (Tmin-c), recovery temperature group (Tr) and Tr control group (Tr-c), With the simulated temperature dropping process of a cold air, collected from Zhangye city in March of 2011, the groups of Tmin and Tr were exposed to this process. Both at the Tmin and Tr, blood were collected from the rats for coagulation function measurements.

RESULTSCompared with the control group, no significant difference was found in the results of activated partial thrombin time(APIT), pro-thrombin time (PF) and thrombin time (TT) between any groups in any strains (P > 0.05). The fibrinogen (Fbg) and fibrinogen-time were found to be obvious higher and shorter in Tmin and Tr of healthy rats and in Tmin of hypertensive rats in contrast to the control group. Hypertensive rats had higher level of fibrinogen and shorter level of fibrinogen-time.

CONCLUSIONThe temperature dropping process induced the increase of plasma Fbg both in the healthy and hypertensive subjects, which might be the reason to explain the higher occurrence of cardiovascular diseases event especially these activated through the formation of thrombin during cold air stress. Besides, the coagulation function of healthy subjects was more likely to be affected by cold air than the hypertensive subjects.
