OBJECTIVETo observe the effect of total flavones of Epimedium leptorrhizum (YYH-C) on osteoporosis in ovariectomized rats.

METHODOvariectomized female rats were randomly divided into the model group, YYH-C lower, middle and high dose (0.7, 1.4, 2.8 g x kg(-1)) groups, the positive drug Bujiale (0.15 mg x kg(-1)) group, and the sham group. The rats were orally ad-ministrated with drugs for three months. Parathyroid hormone (PTH), procollagen I N-terminal peptide (PINP), alkaline phosphatase (ALP), calcium (Ca) and phosphrous (P) in serum were detected. Femur bones and vertebrae bones of left side were collected to determined bone metrological indexes, including bone mineral density (BMD), bone Ca, and bone ash weight/dry weight percentage. Femur bones of right side were collected to for a morphological observation of bone.

RESULTCompared with the sham group, the model group showed significantly higher PTH and ALP content but obviously lower PINP and Ca content. The three YYH-C 3 groups could resist the decrease of PINP. Specifically, low and middle dose groups could remarkably inhibit the increase of PTH, and the high dose group could increase the Ca content in serum, but without significant effect on the rise in ALP. There was no significant difference in P content in serum in each group. BMD, ash weight/dry weight percentage, Ca and P content of the model group were significantly lower than those in the sham group. The high dose YYH-C group could significantly increase BMD. All of the three YYH-C groups could notably increase ash weight/dry weight percentage and Ca, P content in femur bones and vertebrae bones. YYH-C could significantly increase average thickness, area, area percentage of bony trabeculae, cortical bone area percentage of femoral shaft and the number of osteoblasts on the surface of bony trabeculae, and decrease the number of osteoclasts.

CONCLUSIONYYH-C can effectively control the bone mass loss of rats with ovariectomy-induced osteoporosis, prevent the changes in bone microstructure, and inhibit bone absorption, so as to resist high turn-over osteoporosis after ovariectomy.

OBJECTIVE:To explore the effects of PDCA(plan,do,check,action)cycle theory in the ADR monitoring of our hospital. METHODS:The problems of ADR monitoring in our hospital in 2012 were analyzed and intervened by PDCA cycle. The effects of PDCA cycle were evaluated 1 year later. RESULTS:After implementation of PDCA cycle,we had improved the manage-ment system,brought ADR monitoring into the appraisal of clinical pharmacists,established the networking platform of ADR report-ing,strengthened the training of physicians and nurses,the publicty of ADR information and ADR monitoring of important medi-cine. The number of ADR reports increased by 18.37% in 2013,the proportion of new and serious ADR reports obviously in-creased(increasing from 22.28% to 38.42%);in terms of ADR reporting source,the ADR reporting in wards obviously increased (increasing from 8.16% to 43.84%). The proportion of ADR induced by antibiotics or TCM preparation decreased significantly(re-spetively decreasing from 54.52% to 43.84% and 23.03% to 13.30%);in term of ADR clinical manifestations,the proportion of skin and its appendants involved decreased significantly (decreasing from 53.64% to 39.41%). CONCLUSIONS:The application of PDCA cycle obviously improves the management of ADR monitoring in our hospital.

Objective To investigate the prevalence of adult osteofluomsis in the endemic fluomsis areas in Tianjin and to provide scientific foundation for endemic fluorosis.Methods Stratified sampling in 55 villages were selected in 3 areas with slight,moderate and severe fluorosis regions in Tianjin from April to June in 2008.Water fluorine were tested and clinical osteofluorosis examinations were conducted to the population aging 16 and above in the villages.Tweenty villages were selected randomly in the slight,moderate and severe fluorosis regions.X-ray osteofluorosis examination were conducted to patients and suspected patients in these 20 villages.Results The geometric mean fluoride content in the water for the 3 areas were 1.35 mg/L,3.44 mg/L,5.49 mg/L,respectively.The prevalence of osteofluorosis were 36.7%(44/120),20.6%(33/160),39.4%(43/109),respectively.The prevalence of osteofluorosis Was increased gradually(r=0.534,P<0.01)and the symptoms and signs of the disease were more serious(H=84.813,P<0.01).The prevalence of X-ray diagnosis Was increased gradually(r=0.990,P<0.01)and signs of the disease were more severe(H=25.169,P<0.01)with an increase in age.There was no statistical significance of prevalence rate of osteofluorosis between males and females,regardless if it Was a clinical diagnosis(X2=0.343,P>0.05)or an X-ray diagnosis(X2=3.532,P>0.05).Conclusions Adult osteofluorosis to a certain extent is still prevalent in the fluorosis areas in Tianjin.Endemic fluorosis is still rampant.Improving water in fulorosis areas should be mandatory.

OBJECTIVETo compare the clinical efficacy differences between acupoint catgut embedding and Kuntai capsule for perimenopausal syndrome, so as to provide an effective treatment method for perimenopausal syndrome.

METHODSThirty-three cases in the embedding group were treated with acupoint catgut embedding at back-shu points and front-mu points of liver, spleen and kidney combined with syndrome differentiation and disease differentiation, ten days per times; the Kuntai group was treated with oral administration of Kuntai capsule, 4 capsules each time, three times per day. The Kupperman index (KI) was observed in the two groups before treatment after 10 days, 30 days and 60 days of treatment, respectively; the efficacy was evaluated according to the ratio of KI.

RESULTSAfter the treatment, as treatment proceeded, the score of KI and ratio of KI were gradually reduced in two groups; the score of KI and ratio of KI in the embedding group after 10 days of treatment was lower than those in the Kuntai group (both P<0.05); after 10 days of treatment, the total effective rate was 36.4% (12/33) in the embedding group, which was superior to 3.0% (1/33) in the Kuntai group (P<0.05); however, after 30 days and 60 days of treatment, the differences of each index between two groups were not statistically significant (all P>0.05).

CONCLUSIONBoth the acupoint catgut embedding and Kuntai capsule could reduce the score of KI and improve clinical symptoms, and the acupoint catgut embedding has certain advantage on the early stage of treatment.

Objective To investigate the relationship between the expression of MMP-7 in peripher- al blood and esophageal cancer.Methods By using Real time RT-PCR, blood samples from 82 cases with postoperative esophageal cancer were detected.Results 37.8 %(32/82)patients were positive for MMP-7 mRNA expression.MMP-7 mRNA positivity significantly correlated with lymph node metastasis,stage,and hematogeneous metastasis.Recurrent disease was found in 28 of 82 cases. Of 28 patients experiencing re- lapse,15 patients were serially follow-up in every three months.The number positive of MMP-7 mRNA be- fore detection by imaging,at the same time of detection by imaging,and after detection by imaging was 5 cas- es,8 cases and 2 cases respectively.Conclusion Examination of MMP-7 mRNA in peripheral blood during follow-up is useful for early detection of occult recurrence.

Objective To explore the effect of chromosomal abnormality and polygenic inheritance factor in female children with short stature.Methods 1.Chromosome analysis:peripheral blood was drawn for 1 mL and cultured 72 h to analyze chromosome karyotype (Giemsa Banding ) of peripheral lymphocytes.2.Polygenic factor analysis:the children′s final height were estimated based on their parents average height,and analyzed the distribution characteristics of children′s final height and compared the estimate final height with the actual height.Results Eighty-three cases out of the 364 female children with short stature were chromosomal abnormality(22.80%).Among the 83 cases,the 45,XO and 46,X,i(Xq) occupied 70%.The distribution of children target height shifted left,and the target height of 76 cases was lower than 2 standard deviation (-2 s)and the consistency of target height and actual height reached 20.88%.The target height of 7 cases was lower than 2 standard deviation in those whose chromosome turned out to be abnormal,and the consistency of target height and actual height was 8.43%.Conclusions Chromosomal abnormality is one of the most important etiologic agents causing short stature in female children, and polygenic inheritance is another important etiologic agent.

Background Congenital fibrosis of extraocular muscles (CFEOM) affects patient' s appearance and quality of life,and no effective treatment for this disease is available.Imaging study is helpful for exploring the pathogenesis of CFEOM.Objective This study was to describe the characteristics of CFEOM associated with limb movement disorder using magnetic resonance imaging (MRI).Methods A family with CFEOM associated with limb movement disorder was investigated in Renmin Hospital of Wuhan University.Disease history was collected and the pedigree was investigated.Ophthalmologic examinations,including corrected visual acuity,refractive error,slitlamp examination,ophthalmoscopic examination,force of levator palpebrae superioris,ocular movement,eye position,forced duction test,and bell phenomenon examination,were performed.Ocular orbital and cranial MRI was performed in 4 CFEOM patients and 10 normal subjects to compare the structures of the extraocular muscles,motor nerve and cranium.Oral informed consent was obtained from each patient prior to any medical examination.Results A total of 1 1 members from 3 generations were investigated in this study,presenting with 4 cases of disease.The mode of inheritance of this family complied with the Mendelian autosomal dominant inheritance law.Clinical signs included disturbance of eye movement,deviation of eye position,ptosis,lack of Bell sign and positive reaction of passive pull test.In addition,unstable gait,improper body limb alignment,dysphasia and mental retardation were ohserved in 1 patient,which coincided with the diagnostic criteria of type 3 CFEOM.MRI results demonstrated that the levator palpebrae superioris,superior rectus and superior oblique muscle were clearly thinner,and the medial rectus,lateral rectus,inferior rectus muscle were thinning in the patients,showing significant differences in comparison with the normal controls(P＜O.05).The oculomotor and abducens nerves became thinner and even absent in the patients.Cranial MRI showed that Ⅲ-3 in the pedigree with callosum was shorter than that of the normal controls,suggesting that patient suffered from corpus callosum hypoplasia.Meanwhile,cranial MRI indicated the presence of cerebellar hypoplasia and the expansion of the fourth ventricle.Conclusions MRI demonstrates consistent abnormalities of the oculomotor nerves and abducens nerves in the affected individuals in this CFEOM 3 family,and some affected members exhibit two types of central nervous system abnormalities-corpus callosum and cerebellar hypoplasia.These findings suggest that CFEOM 3 is primarily a neuronal disease.

BACKGROUND: Venous thromboembolism (VTE), including both deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common, lethal disorder that affects hospitalized and non-hospitalized patients. This study aimed to review the progress in the research into VTE. DATA SOURCES: We reviewed the studies about VTE and verified different genetic polymoriphisms of VTE. RESULTS: The pathogenesis of VTE involves hereditary and acquired factors. Many studies indicated that the disorder of coagulation and fibirnolytic system is of utmost importance to this disease. Genetic polymoriphism-related VTE demonstrated significant differences among geographies and ethnicities. CONCLUSION: VTE has many risk factors, but genetic factors play an important role.

To investigate the effects of gambognic acid (GA) on TRAIL-induced apoptosis of cancer cells, human colon HT-29 cancer cells were treated with GA to promote apoptosis. Inhibition of the cell proliferation was measured with MTT assay and cell apoptosis was detected with formation of DNA ladders in agarose gel electrophoresis, and activation of caspase activity. The content of cytosolic reactive oxygen species (ROS) was measured with flow cytometry. The activities of Caspase-3, -8, -9 were detected using spectrophotometric assay. The levels of c-FLIP, CHOP, DR4 and DR5 in cells were tested by Western blot. Combination of GA (1 µg · mL(-1)) and TRAIL (40 ng · mL(-1)) significantly reduced proliferation and increased apoptosis of HT-29 cells over those induced by each agent alone. Percentage of apoptotic cells was increased to 45.5%. GA markedly enhanced the intracellular ROS generation. Expression of CHOP, DR4 and DR5 was up-regulated to 7.38, 5.41, and 4.85 times of the control group, respectively. GA promoted activation of Caspase-3, -8, and -9 by TRAIL (P<0.05). Furthermore, the expression of anti-apoptotic protein c-FLIP was down-regulated to 0.22 ± 0.08 times of the control group. In conclusion, GA sensitizes HT-29 cells to TRAIL-induced apoptosis by promoting ROS-activated ERS pathways, up-regulating of DR4 and DR5, and inhibiting c-FLIP expression.
