In Taiwan, the first human-infecting H6N1 avian influenza virus was isolated in 2013. To better understand the origin, evolutionary relationship and pathogenesis of the H6N1 virus, we studied the adaptive evolution and evolutionary dynamics of the hemagglutinin (HA) genes of the H6N1 virus in Taiwan. We felt that such studies woud contribute to the further study and control of the virus. Datasets were gained from the Flu and Global Initiative on Sharing All Influenza Data (GISAID) databases. Then, phylogenetic trees and evolutionary dynamics were reconstructed. The evolutionary rate and characterization of adaptive evolution were analyzed by bioinformatic methods. Results indicated that the HA genes of H6N1 in Taiwan were divided into at least five types, and that the new types that the infected human H6N1 belonged to could be local advantage type at present. Evolutionary dynamics revealed the viral population expanded first at the end of 1971, reduced sharply in 2008, and then increased slightly. Three sites were identified under positive selection, suggesting that various sites might increase the adaptive ability of the virus. Eighty-nine sites were under negative selection, revealing that these sites might play an important role in the replication and epidemiology of the virus. Interestingly, site 329 upstream from the cleavage site was also under negative selection, suggesting that this site might be associated with the virulence of H6N1. These data suggest that the HA genes of the Taiwanese H6N1 virus have been undergoing adaptive evolution, and that an outbreak may occur again. Hence, more attention should be paid to the identified sites, to enable timely monitoring and control of a future epidemic.

OBJECTIVETo investigate the effect and mechanism of Qingxuan Tiaoya Recipe (QXTYR) on depressing blood pressure in menopausal women with hypertension.

METHODSPatients were randomly assigned to two groups, the 44 patients in the test group were administered with perindopril tablet and QXTYR granule, while the 43 in the control group were administered with the same program, but a simulator of QXTYR was used to replace for the real one. The treatment course for them all was 2 months. Before and after treatment, the ambulatory blood pressure (ABMP), heart rate, related clinical symptoms, blood lipids, serum estradiol (E2), high-sensitivity C-reactive protein ( Hs-CRP), homocysteine (HCY) and angiotensin II (Ang II) were measured.

RESULTSThe treatment in the test group showed an effect better than that in the control group in terms of reducing blood pressure variability and night-time blood pressure decrease rate (P <0.05), with the total effective rate and markedly effective rate in lowering blood pressure superior to the control group (P<0.05), alleviating symptoms as headache, soreness and weakness of the waist and knees, and insomnia (P <0.05), and decreasing levels of heart rate, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), Hs-CRP and Ang II (P <0.05), The plasma level of endogenous E2 was elevated after treatment in the test group (P< 0.05), but showed no statistical difference in the control group.

CONCLUSIONSQXTYR shows favorable effect in depressing blood pressure of menopausal women with hypertension, it can reduce blood pressure variability, improve the symptoms of the menopause syndrome, blood lipid metabolism and plasma levels of Hs-CRP, E2, and Ang II in patients, suggesting that its mechanism may be related to the functional regulation of sympathetic-vagus nerve and neuro-endocrine-immune system, and also the inhibition on the circulatory renin-angiotensin-aldosterone system activity.

OBJECTIVETo investigate the efficacy of the locking internal fixator (LIF), which includes the locking compression plate (LCP) and the less invasive stable system (LISS), in the proximal and distal tibial fractures.

METHODSWe did a retrospective study on a total of 98 patients with either proximal or distal tibial fractures from January 2003 to January 2007, who had received the operation with LIF by the minimally invasive plate osteosynthesis (MIPO) technique. The data consisted of 43 proximal tibial fractures (type AO41C3) and 55 distal tibial fractures (type AO43C3).

RESULTSNo complications were observed in all patients after operation. The mean healing time was 8.4 months (range 5-14 months). Only two cases of delayed union occurred at postoperative 10 months. No infections were reported after the definitive surgery even in the cases of open fractures. All patients reached a full range of motion at postoperative 6 to 9 months and regained the normal functions of knee and ankle joints.

CONCLUSIONUsing LIF in MIPO technique is a reliable approach towards the proximal and distal tibial fractures that are not suitable for intramedullary nailing.

OBJECTIVETo observe the efficacy and safety of Yigu capsule (YGC), a Chinese herbal compound preparation, in treating postmenopausal osteoporosis (PMO) and to explore its possible mechanism.

METHODSThe clinical study was conducted in a prospective, randomized, double blinded method lasting for 6 months with placebo and positive control. Two hundred and ten PMO patients with confirmed diagnosis were assigned into the YGC group, the calciferol group and the placebo group. Besides being administered element calcium, they were treated with YGC, calciferol capsule and placebo capsule respectively. And such symptoms as newly found fracture and ostealgia, bone mineral density (BMD) of the 2nd-4th lumbar vertebrae (L(2-4)) and upper femur, blood and urinary indexes for bone metabolism, sex hormone level and adverse reaction that occurred in patients were observed.

RESULTSIn the YGC group, the total effective rate was 95.50%, with no new occurrence of fractures, which was significantly better than that in the other two groups (P < 0.05). Moreover, in the YGC group, the increase rate of BMD was 9.83% in L(2-4), 4.09% in femoral neck, 4.60% in Wards triangle, 3.00% in greater trochanter, which was also better than that in the placebo group (P < 0.05, P < 0.01). As compared with the placebo group, levels in the YGC group of urinary oxyproline hydroxyproline/creatinine, urinary calcium/creatinine were significantly lower, serum and bone alkaline phosphatase, osteocalcin, estradiol and estradiol/testosterone were significantly higher, but no difference was shown in the comparison of testosterone level. In the observation period, no abnormality in blood or urine routine, liver or renal function was found. Only mild, transient gastro-intestinal response occurred in individual patients, but it did not affect the treatment.

CONCLUSIONYGC could treat PMO effectively, as it could obviously increase the BMD of lumbar vertebrae and coxafemoral bone, elevate the alleviating rate of ostealgia and incessant motion time, yet causing no newly found compressive fracture of vertebrae, or and any related adverse reaction. YGC could not only promote the formation, but also inhibit the absorption of bone as well as increase the sex hormone level. Therefore, it is a pure Chinese herbal compound preparation worthy of further research and development.
