Objective To explore the treatment effect of potato homogenate on the treatment of drug extravasation during intravenous injection.Methods 320 cases of drug extravasation patients during the intravenous infusion were randomly divided into the potato homogenategroup,named group A; patato slice group named group B and magnesium sulfate group as group C.The group A,B and C were separately treated with the external application of potato homogenate,thin slice of fresh potato and 33％ magnesium sulfate.The therapeutic effects of the 3 groups were compared.Results The therapeutic effect of group A was superior to that of group B and C,and the healing time in group A was much shorter than that in group B and C,and group B was batter than group C,there was significant difference between the above comparison groups.Conclusions The therapeutic effect of external application of fresh potato in the treatment of extravasation injury caused by the drugs is remarkable.Potato homogenate can improve the treatment effect and shorten healing time when compared with potato slice.

The prescription combinations of traditional Chinese medicine (TCM) focuses on the taste and channel tropism, the Qi movement, as well as the compatibility according to multiple combination principles and medicinal property and flavor combination of several traditional Chinese medicines. With the in-depth study on the prescription compatibility, researchers have realized that the medicinal property theory is the core of TCM combinations. However, there is no definite method for combinations based on medicinal properties. In this paper, the authors put forward an method for designing prescription combinations based on bipartite graph and the greedy algorithm. With the medicinal property combinations of Siweilurong Pills for example, the authors proved this method could provide ideas for quickly choosing herbal medicines for prescription combinations, and discussed the prospect of this method in substituting previous and endangered herbal medicines and banned medicinal materials.

The association of non-HDL-cholesterol and non-HDL-C-to-HDL-cholesterol ratio (non-HDL-C-to-HDL-C ratio) with early diabetic nephropathy in patients with type 2 diabetes mellitus was investigated.Non-HDL-C and non-HDL-C-to-HDL-C ratio were positively related with microalbuminuria (P＜0.05 or P＜0.01).Non-HDL-C-to-HDL-C ratio is an independent risk factor of early diabetic nephropathy in patients with type 2 diabetes mellitus.

OBJECTIVE: To explore the mutation of Y-STR loci in meiotic allelic transmission in a large pedigree. METHODS: The oral swabs of 163 male individuals were collected from a Lin pedigree. Twenty-two Y-STR genetic markers were typed with AGCU Y24 fluorescent detection kit (AGCU Y24 system), which also contained 16 Y-STR markers included in Yfiler multiple amplification kit (Yfiler system). The genotyping results of Y-STR loci were compared between each two males in the pedigree. RESULTS: There were 20 and 30 kinds of haplotypes obtained with Yfiler and AGCU Y24 systems in 163 male individuals from the Lin pedigree, respectively. The rates referred to haplotype differences (RRHD) of these two typing systems between male pairs were 0.910 5 and 0.922 7, respectively. The average number of marker differences were 6.582 1 and 9.824 8, respectively. The RRHD increased along with the incidents of meiosis. CONCLUSION Y-STR mutation leads to different Y-STR haplotypes among the male members in a paternal pedigree and the rate of difference increases along with the incidents of meiosis.

Serum cytokine concentrations were determined in patients with Graves'disease(GD)before and after treatment of thiamazole.Serum soluble interleukin-2 receptor(sIL-2R)level was markedly raised before treatment as compared with normal subjects and returned to normal after 3 month therapy.Serum IL-8 level was lowered in GD patients and showed no change after 3 month therapy.No relationship between IL-8 and other markers was found.Serum IL-1?,IL-6 and TNF-?levels in GD patients showed no difference with those in normal controls.

OBJECTIVETo examine UVB-induced responses in normal human keratinocytes (HaCaT) and epidermoid carcinoma cells (A431) at the cellular and molecular level, and investigated the protective effect of salidroside.

METHODSCells irradiated by UVB at various dosage and their viability was assessed by MTT assays, cell cycle was analysed by flow cytometry. The expression of NF-κB, BCL-2, and CDK6 after 50 J/m(2) UVB irradiation were detected by RT-PCR and western blotting.

RESULTSOur results confirmed greater tolerance of A341 cells to UVB-induced damage such as cell viability and cell cycle arrest, which was accompanied by differential expression changes in NF-κB, BCL-2, and CDK6. UVB exposure resulted in HaCaT cells undergoing G(1)-S phase arrest. When treated with salidroside, HaCaT survival was significantly enhanced following exposure to UVB, suggesting great therapeutic potential for this compound.

CONCLUSIONTaken together, our study suggests that A431 respond differently to UVB than normal HaCaT cells, and supports a role for NF-κB, CDK6, and BCL-2 in UVB-induced cell G(1)-S phase arrest. Furthermore, salidroside can effectively protect HaCaT from UVB irradiation.

OBJECTIVETo explore the relationship between G2139A,G3091A, T663A, and T3593C single nucleotide polymorphisms (SNPs), which are located at the promoter region,13th exon, and 2nd intron of epithelial sodium channel (ENaC) gene, and their haplotypes with essential hypertension (EH) in Kazakhs in Xinjiang.

METHODSA case-control study was conducted including 252 EH patients (EH group) and 254 normotensive subjects (NT group) among Kazakhs in Xinjiang. The four genetic polymorphisms were identified by polymerase chain reaction - restriction fragment length polymorphism. The distribution of the genotypes and alleles in all subjects and the different frequency of these four SNPs between EH group and NT group were analyzed. The linkage disequilibrium and haplotypes of these four SNPs were analyzed.

RESULTSThese four SNPs of alpha ENaC gene existed in Xinjiang Kazakhs. In all subjects, the distribution frequencies of genotypes AA, AG, and GG at G2139A were 26.2%, 52.3%, and 21.5%, respectively, and those of alleles (A, G) were 52.37% and 47.63%. The distribution frequencies of genotypes AA, AG, and GG at G3091A were 19.0%, 52.5%, and 28.5%, respectively, and those of and alleles (A, G) were 45.56% and 59.44%. The distribution frequencies of genotypes AA, AG, and GG at T663A were 15.6%, 49.9%, and 34.5%, respectively, and those of alleles (A, G) were 40.53% and 59.47%. The distribution frequencies of genotypes TT, TC, and CC at T3593C were 88.5%, 10.5%, and 1.0%, respectively, and those of alleles (T, C) were 93.77% and 6.23%. The distribution of genotypes at these four SNPs were all consistent with Hardy-Weinberg equilibrium in this population (P0.05). The distribution frequencies of genotypes and alleles about these four genetic polymorphisms were not significantly different between the EH group and NT group (P0.05). However, the frequencies of two haplotypes were found to be significantly different between these two groups (P0.05). The haplotype frequency which included 2139G, 3091A, 663G, and 3593T alleles was significantly increased in EH group (P0.01), while the haplotype frequency which included 2139A, 3091A, 663A, and 3593C alleles was significantly increased in NT group (P0.05).

CONCLUSIONSThe haplotypes that are composed of G2139A, G3091A, T663A, and T3593C polymorphisms of alphaENaC gene may play an important role in the development of EH among Kazakhs in Xinjiang. The haplotypes that are composed of 2139G, 3091A, 663G, and 3593T alleles may aggravate the development of EH. The haplotypes that composed of 2139A, 3091A, 663A, and 3593C alleles may decrease the risk of EH among Kazakhs.
