Objective By X-ray measurement of metacarpal and phalange bones in the right hand of adult patients with Kaschin-Beck disease in Qinghai Province,to provide anatomic data and information for clinic diagnosis of the disease and application of hand surgery.Methods Fifty-four cases of adult patients with Kaschin-Beck disease,who came from Guide County and Xinghai County in Hainan Prefecture,Qinghai Province,were selected as investigation subjects,then their right hand X-ray film were taken,metacarpal and phalange bones were measured by electronic digital vernier caliper.All data were analyzed with SPSS 19.0.Results The axis length of the metacarpal bones was in the order of:the 2nd metacarpal ＞ 3rd metacarpal ＞ 4th metacarpal ＞ 5th metacarpal ＞ first metacarpal.The axis length of proximal phalange bones was in the order of:the middle finger proximal ＞ ring finger proximal ＞ index finger proximal ＞ little finger proximal ＞ proximal thumb,while the middle,distal phalanx axis length varied greatly.The length of metacarpal and phalange bones of all male was longer than that of female(all P ＜ 0.01).The width of the metacarpal bones was in the order of:the 2nd metacarpal ＞ 3rd metacarpal ＞ 5th metacarpal ＞ 4th metacarpal.The width of the 2nd-5th metacarpal of male and female was (8.57 ± 0.90),(8.25 ± 0.80),(6.84 ± 0.69),(7.70 ± 0.77)mm and (7.40 ± 0.74),(7.36 ± 0.70),(6.00 ± 0.57),(6.62 ± 0.65)mm,respectively,the differences were significant(t =5.24,4.32,4.85,5.55,all P ＜ 0.01).The matacarpal bone index of female[(8.23 ± 0.90)mm] was significantly larger than that of male[(7.61 ± 0.76)mm,t =2.73,P ＜ 0.01].Conclusion X-ray measurement of hand may provide reference information for diagnosis of Kaschin-Beck disease and determination of metacarpal and phalange length in hand surgery.

Objective By investigating newly diagnosed Kashin-beck disease,to understand distribution range,epidemic intensity and prevalence trend of Kashin-Beck disease(KBD)in Xinghai County.Method According to monitoring method on national KBD,we carried on epidemical investigation,clinical examination and X-ray photograph on school children aged 7-13 years in 6 villages from 4 towns in Xinghai County,and hair,grain,water and soil were sampled to detect selenium content using naphthalene fluorescence.Resuit Three hundred and seventy.three school children aged 7-13 years underwent the clinical examination,the prevalence rate was 12.06%(45/373);347 school children were went on X-ray,the detection rate of X-ray was 21.61%(75/347).The selenium content was the lowest in Quanqu Village,Ziketan Town,which were(77.70±42.04),(7.44±6.93)μg/kg respectively;the selenium content Was highest in Cainaihai Village,Qushian Town,which were(103.88±58.57),(29.58±24.11)μg/kg respectively;level of in internal and external environment in 4 KBD region were all low.Conclusion These four region are new KBD region.The prevalence state of KBD is serious,pathogenetic factor of Kashin-Beck disease is very active.

ObjectiveTo compare the effect of amiodaron and propafenone on the cardioversion of paroxysmal auricular fibrillation (PAF). Methods58 PAF (≤48 h) cases were radomly divide into two groups: 30 cases who accepted amiodaron 150 mg intravenous injection, and 0.6～1.0 mg/min intravenous drip afterwards in amiodaron group, other 28 cases who accepted propafenone 1.4～2.0 mg/kg vein injection, and 0.28 mg/min intravenous drip afterwards in propafenone group.If propafenone was not effective, the cases in propafenone group were given amidoaron. ResultsThe successful reversion rate was 86.7% (26/30) in amidoaron group while 57.1% (16/28) in propafenone group(P<0.05). The mean time of recovering was (101±95) min (6～508 min) in amidoaron group, while (172±148) min (11～608 min) in propafenone group(P<0.05). ConclusionIt is more rapid and effective of amidoaron on the cardioversion of paroxysmal auricular fibrillation than propafenone is.

Objective To assess characteristics of coronary artery lesions and risk factors of coronary heart disease (CHD) in young people with coronary arteriography.Methods 192 patients with CHD diagnosed by coronary arteriography were divided into the young group (91 cases, 25—40 years old) and senile group (101 cases, 41—84 years old). Characteristics of coronary artery lesions and risk factors of CHD of two groups were analyzed, and risk factors were especially tested with logistic regression.Results Coronary artery lesions in the young group were characterized in most patients by singles vessel lesion (64%), while by multi vessels lesion (71%) in the senile group. Multiple logistic regression analysis showed that risk factors such as male, smoking, hyperlipemia, family history and increassed C-reactive protein (CRP) were highly related with CHD(P<0.01).Conclusion Single vessel lesion is a feature of young patients with CHD, and independent and related risk factors of CHD in the young group are male, smoking, hyperlipemia, CHD family history and CRP.

There is immense interest in the long-chain polyunsaturated fatty acids(LC-PUFAs) on account of their health-beneficial properties.There has been considerable interest in the production of LC-PUFAs in transgenic plants to provide a cheap,sustainable and clean source of these fatty acids.Several main LC-PUFAs,their roles and metabolic pathway in plant are introducedbriefly,progresses on biosynthesis of LC-PUFAs in transgenic plant are reviewed,and strategies for improving the yields of LC-PUFAs in plant are also discussed.

Many unusual fatty acids present in the seed oils of non-food plants are modified at the ?12 position either by the addition of epoxy or hydroxy groups or by the formation of triple (acetylenic) bonds or conjugated double bonds. The introduction of these functionalities into C18 fatty acids is catalyzed by a family of divergent forms of the fatty-acid ?12-desaturase (FAD2) enzyme. Genes encoding these enzymes have now been cloned from a variety of organisms and expressed in transgenic oilseeds. However,the accumulation of the intended fatty acids in transgenic plants has been relatively disappointing,and the mechanisms of these unusual fatty acids biosynthesis and transferring from phosphatidylcholine into storage triacylglycerols still need to be elucidated.

Cellulase was produced by growing Penicillium sp. NXP25 in liquid medium consisted of 5% com cob powder, 3% wheat bran, 0.35% nitrogen source No 10 and 0.3% calcium chloride. The optimum culture conditions were initial pH 5.0, 10% mycelial inoculum, temperature 29℃, shaking speed 280r/min and cultivation time 72h. When determining enzyme activity at 50℃, endo-1, 4-?-glucanase activity, extro-1, 4-?-glucanase activity, ?-glucosidase activity and filter paper enzyme activity of the supernatant of the culture were 841u/mL, 13u/mL, 24u/mL and 46u/mL, respectively. The optimum pH and temperature for the action of the above enzymes were pH 4.8 and60℃, pH5.0 and 50℃, pH 4.5 and 70℃, pH 5.0 and 55℃, respectively. Stable pH range of the above enzymes were 3.0-7.0, 4.0~6.0, 4.0~7.0 and 4.0~6.0, respectively. After incubating the enzyme complex at 65C for 30min, 24% of endo-1, 4-?-glucanase activity, 7% of extro-1, 4-?-glucanase activity, 89%of ?-glucosidase activity and 8% of filter paper enzyme activity were remained, respctively.
