Objective: To explore the core composition and compatibility features of Ershiwuwei Songshi pills in the treatment of liver disease, in order to provide ideas and methods for the optimization of Tibetan medicine prescriptions and the creation of new medicine. Methods: In this study, I checked common prescriptions for the treatment of liver diseases from the Tibetan Medical Classics, such as Four Medical Classics, Xin Xiu Jing Zhu Ben Cao, etc., summarizing the flavor, nature and efficacy of the 25 herbs in Ershiwuwei Songshi pill, and analyzing the compatibility features of flavor and of nature and efficacy of the 25 herbs in Ershiwuwei Songshi pill. And I also sorted out 21 common prescriptions for the treatment of liver diseases in the Tibetan Medical formula, counting and analyzing the using frequency of the ingredient medicine of Ershiwuwei Songshi pill in the 21 Tibetan medical formula for the treatment of liver and the compatibility frequency. Conclusion: The results show that Ershiwuwei Songshi pills are composed of a heat clearing formula, mainly for the treatment of heat liver diseases.

To explore the related risk factors and outcome in pregnancy- induced hypertension patients with Ⅲ phase of retinopathy.
●METHODS: A total of 105 pregnancy - induced hypertension patients with Ⅲ phase of retinopathy in our hospital from Januany 2012 to December 2013 were enrolled. Clinical date of them were collected to analyze.
●RESULTS: The occurrence of pregnancy - induced hypertension patients with Ⅲ phase of retinopathy were positively correlated with the course of the disease, blood pressure, proteinuria, and it was higher occurred in cold winter and spring, timely termination of pregnancy and appropriate hormone therapy can promote the recovery of vision, and improve outcomes of pregnancy.
●CONCLUSlON: The occurrence of pregnancy - induced hypertension patients with Ⅲ phase of retinopathy associated with season and disease severity. Timely treatment can restore normal vision, improve maternal and neonatal prognosis. Routine examination of fundus examination should be used as the pregnancy induced hypertension syndrome.

OBJECTIVETo systematically explore the occurrence of a novel type of chromosome translocation in human sperm samples.

METHODSSpecific translocation junction fragments were quantified using nested and/or multi-nested PCR in sperm DNA derived from 28 oligospermic patients and 32 normal controls.

RESULTSt(11;22) was detected in 49 samples. At least 4 samples were found to have t(1;22) (p21.2;q11.2), t(17;22) (q11;q11) or t(X;22) (q27;q11). The mutation rate seemed to be associated not with age or semen volume, but with sperm concentration (r = -0.389, P < 0.05) and motility (r = -0.397, P < 0.05). Correlation was not found between homology of palindromic sequences and mutation rate.

CONCLUSIONPalindromic sequence mediated chromosome translocation is common in human sperm, and associated with sperm concentration and motility. Measurement of such mutations may provide a molecular-level reference for assessing sperm quality.

OBJECTIVETo investigate contrast-enhanced ultrasound imaging features of diabetic foot ulcers.

METHODSSixteen patients with diabetic foot ulcers underwent conventional and contrast-enhanced ultrasound examinations, and the features of contrast-enhanced ultrasound imaging were analyzed. Pathological examination was also carried out in some cases.

RESULTSContrast-enhanced ultrasound showed slow enhancement in the artery phase in the 16 ulcers after administration of SonoVue. The mean time of initial enhancement was 30.02 ± 2.35 s, and the mean time for the occurrence of peak enhancement was 37.54 ± 4.13 s. In 5 cases a homogeneous enhancement pattern was clearly displayed, and in the other 11 cases, a pattern of homogenous peripheral enhancement with non-enhanced patches within the ulcers was found. Contrast-enhanced ultrasound showed a greater ulcerous area than conventional ultrasound.

CONCLUSIONContrast-enhanced ultrasound is a valuable means for evaluating the ulcerous area and the treatment efficacy for diabetic foot ulcers.

The src homology 2 (SH2)-domain containing inositol-5-phosphatase (SHIP) is another recently identified lipid phosphatase after phosphatase and tensin homology deleted on chromosome ten gene (PTEN). It plays an important role in negatively regulating the proliferation of hematopoietic cells. The relationship between SHIP and the inhibition of tumor proliferation is rarely reported. The purpose of this study is to evaluate the apoptosis induced by SHIP gene in K562 cell line and to explore the involved signaling pathway. The K562 cells were transfected with human SHIP gene by using the lentiviral vector containing SHIP, and the transfection was verified by fluorescent quantitative PCR (FQ-PCR) and Western blot. Then the effects of SHIP protein expression on cell growth and apoptosis were measured. The levels of p-Akt, bcl-2 family, caspase and the activity of NFkappaB were assayed by Western blot and ELISA, respectively. The results are as follows: (1) Human leukemia cell line K562 was SHIP-negative; (2) Transfection with SHIP gene led to the re-expression of SHIP mRNA and protein in K562, as shown by FQ-PCR and Western blot; (3) The expression of SHIP protein inhibited cell growth and significantly increased apoptosis in K562 cells; (4) Compared to that in control group, the expression level of p-Akt-308 and p-Akt-473 in SHIP-expressing cell group decreased significantly (P<0.01); SHIP activated caspase-9, caspase-3, up-regulated protein levels of bad, p27, down-regulated expression of bcl-xL, while it had no effect on the expression of bcl-2 and bax. Furthermore, the inhibition of NF-kappaB was achieved along with the inactivation of Akt. These data suggest that SHIP gene has potential abilities to inhibit K562 leukemic cell proliferation and induce its apoptosis via inactivating PI3K/Akt pathway. The loss of SHIP might be the explanation of aberrant high-level p-Akt in human leukemia. It may be at least one of the mechanisms by which the loss of SHIP expression contributes to leukemia progression.
