Fhx/P25 in silkworm, Bombyx mori, one of the main components of silk fibroin, is presumed in previous reports to be expressed exclusively in the posterior silk gland (PSG) of the animal with strict territorial and developmental specificities. On the basis of a large-scale analysis ofthe silkworm EST data, it was found that Fhx/P25 gene is transcribed not only in the posterior silk gland, but in the ovary and in other tissues of the larvae at day 3 of the fifth-instar as well and that this gene has distinct transcription start sites (TSSs) in the posterior silk gland and the ovary. The TSS in the ovary is located about 115 bp upstream sequence of that in the posterior silk gland. Subsequent RT-PCR, FQ-PCR and sequencing have verified the validity of this presumption. In addition, alternative splicing is predicted in pre-mRNA of Fhx/P25 gene and confirmed by RT-PCR. In conclusion, Fhx/P25 gene is not a gene with strictly tissue-specific transcription.Complicated regulation mechanisms may exist for its transcription and expression and it may have other functions to perform.

Objective To investigate the inhibitory effect of octreotide on transforming growth factor-alpha (TGF-?)-induced cell proliferation of human hepatocellular carcinoma cells and its possible mechanism. Methods The effect of octreotide on TGF-?-induced cell proliferation of the liver cancer cells (LCC) was evaluated by immunohistochemistry method. The effect of octreotide on TGF-? secretion and epidermal growth factor receptor(EGFR) expression in the cells was determined by reverse-transcriptase polymerase chain reaction(RT-PCR). The effect of octreotide on extracellular signal-regulated protein kinase (ERK) expression in the cells was measured by Western-blot and immunohistochemistry method. Results The TGF-?-induced expressions of proliferating cell nuclear antigen (PCNA) in nucleus were obviously increased by TGF-?. TGF-?mRNA index of hepatocellular carcinoma cells was decreased by octreotide. Octreotide inhibited significantly the expressions of EGFR mRNA induced by TGF-?. Octreotide inhibited significantly the expressions of ERK protein induced by TGF-?. There was intense staining in the nucleus of the cells by TGF-? and weak staining in the nucleus of the cells treated simultaneously by octreotide and TGF-?.Conclusions Octreotide can inhibit the secretion of TGF-?, the expression of EGFR, and the signal transduction of EGFR of LCC, and consequently exerts an inhibitory effect on TGF-?-induced hepatocellular carcinoma cells proliferation.

ObjectiveTo investigate the distribution of Kashin-Beck disease(KBD) in Tibet, and assess the disease status. Methods Between 2007 and 2008, a survey was done on KBDepidemiology which was carried out in four prefectures of 26 counties according to the east, south, west, north and center in Nakchu,Lhoca, Nyingtri and Shigatse districts of Tibet, with towns and villages as baseline survey points. According to the KBD e survey scheme, KBD clinical examination for adults was also carried out and at the same time clinical and right hand anteroposterior X-ray examinations were given to children aged 4 - 13. The partition of endemic area was based on the criteria of national standards for Kashin-Beck disease diagnoses《GB 16395-1996》. Slight KBD area:clinical prevalence of Kashin-Beck disease grade Ⅰ and above was less than 10％ or X-ray detection rate ＜ 10％ of children; the moderate prevalent KBD area: clinical prevalence of Kashin-Beck disease grade Ⅰ and above was between 10％ and 20％ or X-ray detection rate was between 10％ and 30％ of children; severe KBD area: clinical prevalence of KBD grade Ⅰ and above was more than 20％ or X-ray detection rate was higher than 30％ of children.ResultsA total of 108 townships of 26 counties were surveyed, 14 686 adults were clinically examined, cases detection of grade Ⅰ and above were 637 people, the prevalence was 4.34％, and no case of grade Ⅲ was detected.Of 5769 children's right anteroposterior X-ray film, 102 were detected positive; the prevalence rate was 1.77％.Metaphysis was affected in most of the child cases, which accounting for 89.2％ (91/102). Amongst all the counties, there were 10 counties, clinical detection rate of adult KBD was 0, and children's X-ray detection rate of KBD was also 0. In 1 county the clinical prevalence rate for adults KBD was 0 and X-ray detection rate for children was 3.66(7/191 ). In 12 counties the clinical prevalence rate for adults KBD was between 1.03％ and 7.54％, X-ray detection rate for children was between 0 and 7.76％, amongst all these counties surveyed there were 5 counties,the detection rate for children was 0. In 3 counties the clinical prevalence rate for adult KBD was between 10.69％and 13.88％, the X-ray detection rate for children was between 5.31％ and 7.76％. Conclusions According to the criteria for diagnoses of KBD, within the 26 counties surveyed, 10 counties are non-endemic areas, 13 counties are slight endemic areas, 3 counties are medium endemic areas. So far, KBD is prevalent in 52 counties of 7 prefectures (cities) in Tibet, the disease is widely distributed, the situation is still severe, and there is a need to continue to strengthen KBD surveillance.

ObjectiveTo evaluate the effects of angiotensin Ⅱ (Ang Ⅱ )infusion on renal c-Abl expression in vivo,and on podocyte c-Abl expression change in cultured mouse podocytes.Methods Twenty four male Sprague-Dawley rats (Group C,D,E and F) were assigned to receive Ang Ⅱ(400 ng· kg-1 min-1) by osmotic minipump and of which 12 rats (Group D and F) were assigned to receive telmisartan (3 mg·kg-1·d-1),six rats received normal saline(Group B),and six rats were used as normal control(Group A).Animals were sacrificed at day 14 (Group C and D),day 28 (Group E and F) respectively.Conditionally immortalized mouse podocytes were used in vitro.Podocytes were studied 2 weeks after thermoswitching from 33℃ to 37℃.Cells were fetal bovine serum(FBS) starved for at least 12 hours prior to stimulation.The cultured podocytes were treated withAngⅡdosesranging from10 -9 mol/L to10 -6 mol/L andfor differenthours.Expression of renal and podocytes c-Abl was examined by immunofluorescence staining,real-time PCR and Western blotting.Results(1) Distribution of c-Abl expression was mainly in the cytoplasm and nuclear of the podocytes in vivo and in vitro. (2) Expressions of c-Abl mRNA and protein wereincreasedinAng Ⅱ-infusedratpodocytesandAng Ⅱ-inducedculturedmouse podocytes(P＜0.05),and the effects of Ang Ⅱ were dose-dependent and time-dependent in vitro.Conclusion There are c-Abl mRNA and protein expression in podocytes,and c-Abl may play a critical role in the pathogenesis of Ang Ⅱ -induced podocyte injury.

OBJECTIVE: To explore the correlations between symptom-based principal factors of rheumatoid arthritis (RA) and the effect of traditional Chinese medicine or Western medicine on RA after factor analysis of RA symptoms. METHODS: Four hundred and thirteen RA patients from 9 clinical centers were included in the clinical trial. They were randomly divided into Western medicine (WM) treated group with 204 cases and traditional Chinese medicine (CM) treated group with 209 cases. A complete physical examination and 18 common clinical manifestations were recorded before the randomization and after the treatment. The WM therapy included voltaren extended action tablet, methotrexate and sulfasalazine. The CM therapy included glucosidorum Tripterygll totorum tablet and Yishen Juanbi Tablet. The American College of Rheumatology 20 (ACR20) was used for efficacy evaluation. All data were analyzed on SAS 8.2 statistical package. Eighteen symptoms in the RA patients were analyzed by factor analysis and the relationships between the factors and effects were analyzed with Chi-Square test. RESULTS: Four principal factors were obtained from the analysis results of the 18 symptoms. The factors could represent the symptoms related to joints, cold-syndrome, deficiency syndrome and heat-syndrome in traditional Chinese medicine (TCM), respectively. The effect of WM therapy was better than CM therapy. After 12 weeks of treatment, the effect of CM on patients without deficiency-syndrome was better than the patients with deficiency-syndrome. After 24 weeks of treatment, WM therapy showed better effect on patients with cold syndrome than patients without cold syndrome. CONCLUSION: The results based on the factor analysis of RA symptoms are similar to the results of syndrome differentiation of TCM, and the factor-related different categories of symptoms are associated with the curative effect, thus further research on the symptoms is necessary.

OBJECTIVETo observe the clinical efficacy of Safflower Injection (Al) in treating and preventing the vascular crisis after free flap transplantation.

METHODSSixty patients undergoing free flap transplantation were randomly assigned to the treatment group and control group according to the visiting sequence, thirty in each. Free flap transplantation was performed on all patients, and medication was given 0. 5 h before flap vascular anastomosis, 1-7 days after surgery. Twenty mL Al was intravenously dripped to patients in the treatment group after adding in 250 mL 5% glucose injection, while Dextran-40 was intravenously dripped to patients in the control group. The medication was conducted once per day. The hemorheology and four indices of blood coagulation [prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (APTT), fibrinogen (FIB)] were compared between the two groups before operation (TO), during operation (T1), 24 h after operation (T2), three days after operation (T3), and seven days after operation (T4). Meanwhile, flaps were observed and adverse reaction recorded. The clinical efficacy and safety were compared.

RESULTSBetter result was obtained in the treatment group when compared their clinical efficacy (86. 67% vs 60. 00%, P<0.05). The whole blood high and low viscosity, plasma viscosity, red blood cell (RBC) volume, RBC aggregation index all decreased, and RBC deformed index increased in the two groups at T4, showing statistical difference when compared with those at T3 (P<0.05, P<0.01). There was no statistical significance in the four indices of blood coagulation when compared with any time point in the same group (P>0.05). There was no statistical significance in hemorheology and the four indices of blood coagulation between the two groups at the same time point (P>0.05). The adverse reaction rate in the treatment group was lower than that in the control group, showing statistical difference (13.33% vs 30.00%, P<0.05).

CONCLUSIONSAI could effectively prevent and treat the vascular crisis after free flap transplantation. It had less adverse reaction and good safety. It was better than Dextran-40. It was a safe and effective drug to prevent the vascular crisis.
