OBJECTIVETo observe and evaluate the clinical effect of acupuncture at "Siguan" combined with the Gallbladder Meridian acupoints on migraine.

METHODSWith randomized controlled trial design, 87 patients were randomly divided into an observation group (42 cases) and a control group (45 cases). The observation group was treated with acupuncture at "Siguan" including Hegu (LI 4) and Taichong (LR 3), combined with the Gallbladder Meridian acupoints including Fengchi (GB 20), Shuaigu (GB 8), Qiuxu (GB 40) and Zulinqi (GB 41), while the control group was treated with acupuncture at the Gallbladder Meridian acupoints, including Fengchi (GB 20), Shuaigu (GB 8), Qiuxu (GB 40), Zulinqi (GB 41), Yanglingquan (GB 34) and Hanyan (GB 4). The treatment was given every other day in two groups, 3 times per week for totally 6 weeks. The migraine intensity, migraine frequency and lasting time of each migraine were observed before and after treatment, and 3-month follow-up was performed after treatment. The clinical efficacy in two groups was evaluated.

RESULTSCompared with those before treatment, the migraine intensity, frequency and lasting time were all reduced significantly after treatment in the two groups (all P<0.01), which were more obvious in the observation group (all P<0.05). At the end of the treatment, the total effective rate was 95.2% (40/42) in the observation group and 80.0% (36/45) in the control group, which had statistical difference (P<0.05). After 3-month follow-up, the total effective rate was 88.1% (37/42) in the observation group and 75.6% (34/45) in the control group, which had no statistical difference (P>0.05).

CONCLUSIONThe "Siguan" combined with the Gallbladder Meridian acupoints could significantly relieve the migraine intensity, frequency and lasting time, and its improvement of symptoms and short-term efficacy are superior to those of the Gallbladder Meridian acupoints alone.

OBJECTIVETo observe the effect of Kanli Granule (KG) on myocardial mechanics in pressure overload induced diastolic heart failure (DHF) rats.

METHODSTotally 60 male Wistar rats were divided into the sham-operation group, the model group, the KG group, and the Valsartan group according to random digit table, 15 in each group. The pressure overload induced DHF model was established in all groups except the sham-operation group using abdominal aortic constriction surgery. Totally 7 rats died after modeling (with the mortality of 10. 67%) , and the rest 53 finished the following test. Rats in the KG group were administered with KG extract (calculated as 6. 75 g crude drug/kg) by gastrogavage. Rats in the Valsartan group were administered with Valsartan (7.2 µg/g) by gastrogavage. Equal volume of double distilled water was administered to rats in the model group and the sham-operation group by gastrogavage. All rats were intervened for 32 weeks. The response of isolated heart papillary muscle tonus to isoprenaline (ISO) and adenylate cyclase (Forskolin) was respectively observed. The enhancement phenomenon after resting development force (DF) of isolated heart papillary muscle tonus, and changes of DF in different Ca²⁺ concentrations were observed.

RESULTS(1) In the ISO response test: Compared with the sham-operation group, the amplifications of DF, ±df/dt, -df/dt were obviously elevated in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously lowered in the KG group (P < 0.01), and the amplification of ±df/dt was also reduced in the Valsartan group (P < 0.01). (2) In the Forskolin response test: Compared with the sham-operation group, the amplifications of DF and ±df/dt obviously increased in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously reduced in the KG group (P < 0.01), and the amplification of DF was also reduced in the Valsartan group (P < 0.05). (3) In post-resting DF enhancement test: Compared with the sham-operation group, the amplification of DF showed gradually decreasing tendency along with prolonged resting time in the model group, and they were obviously lowered at all time points (P < 0.05). Compared with the model group, the amplification of DF was gradually increasing along with prolonged resting time in the KG group. The amplification of DF at post-resting 240 s was obviously larger in the KG group than in the model group (P < 0.05). The amplification of post-resting DF still showed gradually decreasing tendency along with prolonged resting time in the Valsartan group, with increased amplifications of DF at post-resting 60 s and 120 s (P < 0. 05) (4) The amplifications of DF in different Ca²⁺ concentrations: Compared with the sham-operation group, the amplifications of DF were significantly elevated in different Ca²⁺ concentrations (1.75, 3.5, 7.0 mmol/L ) (P < 0.05, P < 0.01). Compared with the model group, there was no statistical difference in amplification of DF in different Ca²⁺ concentrations in the KG group (P > 0.05). The amplifications of DF in different Ca²⁺ concentrations were significantly reduced in the Valsartan group (P < 0.05).

CONCLUSIONSThe ISO response and the Forskolin response were enhanced in isolated heart papillary muscle tonus of pressure overload induced DHF rats; enhanced post-resting DF was reduced; DF in different supra-physiologic levels of Ca²⁺ was still enhanced. KG could significantly improve excessive enhancement of pressure overload induced DHF rats in ISO response and Forskolin response, and improve enhancement of post-resting myocardium.

AIM:To investigate the ability of a metal complex ammonium tetrathiomolybdate (ATTM) to re-lease H2 S and its cytoprotective effect on an oxidative injury model .METHODS:Released H2 S was absorbed in a reaction flask from ATTM dissolved in the cell medium .Staining with dichlorodihydrofluorescein diacetate or rhodamine 123 fol-lowed by photofluorography was conducted for the observation of reactive oxygen species ( ROS) and mitochondrial mem-brane potential (ΔΨm) levels, respectively.Cell viability and release of lactate dehydrogenase (LDH) from the cells were measured with commercial kits.RESULTS:Similar to another H2S donor GYY4137, ATTM had an ability to release H2S in the cell medium in a dose-dependent manner .Treatment of human skin HaCaT cells with ATTM at concentrations of 25~400 μmol/L didn’ t significantly alter cell viability .Exposure of the cells to ultraviolet rays or a ROS donor H 2 O2 in-creased the intracellular ROS levels .Treatment with 400 μmol/L H2 O2 significantly reduced the viability of HaCaT cells (P<0.01).However, before the treatment with H2O2, pretreatment with ATTM at 100 and 200 μmol/L markedly pre-vented the H2O2-induced cell injury (P<0.01).In addition, the treatment with H2O2 triggeredΔΨm loss (P<0.01) and LDH release from the cells (P<0.01).Prior to suffering from H2O2 injury, the preconditioning with 200 μmol/L ATTM significantly improved ΔΨm levels ( P<0.05 ) and attenuated LDH release from the cells ( P<0.01 ) .CONCLUSION:ATTM is capable of releasing H 2 S and protecting human skin cells against oxidative injury .

Objective To establish an optimal animal model of pulmonary metastasis of human lung adenocarcino-ma, to serve further investigation of mechanism of lung adenocarcinoma metastasis.Methods Eleven nude mice aged 4-6 weeks were used in this study.Suspension of human lung adnocarcinoma A549 cells (0.1 mL, 107 cells/mL) was injec-ted into the tail vein in nude mice.From four weeks after inoculation, two nude mice were killed each time at 4, 5, 6 weeks after the tumor cell injection at random for examination.The remaining 3 mice were killed at the end of the experi-ment.At autopsy, the lung, brain, liver, kidney and other organs were removed, fixed in neutral buffered formalin and embedded in paraffin.Sections were cut and stained with hematoxylin-eosin, and examined by histopathology.The number of metastatic foci was counted.Results No mouse died after tumor cell inoculation.Serially euthanized mice revealed evi-dence of gradually increasing pulmonary metastases in the mice:No metastasis was found before 4 weeks after tumor cell in-oculation, the first histological metastases appeared at 5 weeks, gross metastatic foci were observed at 6 weeks, widely spread metastatic foci were observed at 7 weeks, and the remain 3 mice developed cachesia at 11, 13, and 14 weeks after tumor cell inoculation.Mediastinal lymph node metastases were found in the nude mice by 11 weeks after tumor cell inocu-lation.Conclusions We have successfully established a nude mouse model of pulmonary metastasis by injecting human lung adenocarcinoma A549 cells into the tail vein.

Objective To explore the value of color doppler ultrasonography by bed side in the early diagnosis of HIE in full term neonates.Methods The changes of cerebral parenchymal and cerebral arterial blood stream parameter on 35 cases of neonates clinically diagnosed HIE of mild and moderate degree and 40 cases of normal newborns on the 24,48 and 72 hours after birth were observed by color doppler ultrasonography by bed side.Results 1.The cerebral parenchyma was even echo in normal newborns,but it was maldistributed and reinforced in mild asphyxia neonates and it was more serious in moderate degree.The echo of cerebral parenchyma in mild degree was near normal in 48 hours after birth,while the echo of cerebral parenchyma in moderate degree was still maldistributed and reinforced in 48 and 72 hours after birth.2.There was obvious changes in the cerebral arterial blood stream parameter and hemodynamics of the asphyxia newborns compared with normals.The systolic peak velocity(Vs)and end diastolic velocity(Vd)of the cerebral arteries in mild and moderate degree were obviously lower than that of control group in 24,48 hours after birth(Pa0.05).3.Resistance index(RI)of the cerebral arteries in mild and moderate degree were higher than that of control group in 24,48 hours after birth(Pa0.05).Conclusion Color doppler ultrasonography by bed side is a convenient,noninvasive method for diagnosing HIE.

Based on the conserved region nucleotide sequences of five potato viruses/viroid(Alfalfa Mosaic Virus,ALMV;Cucumber mosaic virus,CMV;Cucumber mosaic virus-satellite,CMV-sat;Potato virus Y,PVY;Potato spindle tuber viroid,PSTVd) and one inner control(18S rRNA),the microarray containing specific oligonucleotide probes and PCR probes were designed and fabricated.The effects of probe concentration,hybridization time,hybridization temperature and spotting solutions on microarray hybridiazation were evaluated.Finally the specificity of optimized plant virus detection array was validated.No significant effect on hybridization signal intensity was observed when the concentration of the oligonucleotide probes ranged from 5 to 20 ?mol/L,there was a linear relationship between the concentration of PCR probe and hybridization signal intensity.The greatest signal intensity were obtained when hybridized at 45℃ for 4 h,and the oligonucleotide probes and PCR probes had a similar effect on microarray hybrization.Among the different spotting solutions,DMSO produced a good reproducibility.The plant virus could be detected specifically by oligonucleotide probe microarray and PCR probe microarray after optimization.

Objective To understand the prevalence,drug resistance and clinical features of children with acute lower respiratory tract infection(ALRI) caused by escherichia coli.Methods From Oct. 2005 to Oct. 2006,659 patients with ALRI who were admitted to hospital were chosen and their nasopharyngeal secretions were obtained and cultured.K-B disc diffusion for antibiotic susceptibility were performed for these clinical isolates.Results Among 659 patients,118 cases were isolated escherichia coli,the rate was 17.99% which had 90 boys and 28 girls.Eighty-seven of 118 E.coli strains were with extended-spectrum ?-lactamase(ESBLs),the rate was 73.73%.All of strains were sensitive to imipenem.For ESBLs-producing strains,the ratio of resistance tocefotaxime,ceftriaxone,cefuroxime,ampicillin,piperacillin were 78.81%,73.73%,73.73%,76.27%,78.81%,respectively.Conclusions The positive rate of ESBLs producing E coli in Kunming area is high and drug resistance is severe gradually.Imipenem can be the first selection for treatment on these infections.

OBJECTIVETo observe the therapeutic effect of Qilin Pills combined with clomiphene on idiopathic oligoasthenospermia.

METHODSWe randomly assigned 300 patients with idiopathic oligoasthenospermia to a trial (n = 156) and a control group (n = 144) to be treated with Qilin Pills (6 g, tid) combined with clomiphene (50 mg, qd) and clomiphene alone (50 mg, qd), respectively, both for a course of 12 weeks. Before and after 4, 8, and 12 weeks of medication, we determined sperm concentration, the percentages of grade a and grade a + b sperm, sperm motility, and the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T), followed by evaluation of the clinical efficacy of Qilin Pills with the pregnancy rate in the patients' spouses as the secondaty therapeutic indexes.

RESULTSCompared with the baseline, both groups of patients showed remarkably improved semen parameters and hormone levels after treatment (all P < 0.01). After 4, 8, and 12 weeks of medication, statistically significant differences were observed between the trial and control groups in sperm concentration ([17.06 ± 2.24] vs [15.07 ± 2.48], [22.10 ± 2.65] vs [18.11 ± 2.97], and [28.13 ± 3.59] vs [21.21 ± 3.60] x 10(6)/mL, P < 0.01), the percentage of grade a sperm ([15.03 ± 2.39] vs [13.08 ± 2.51], [21.08 ± 3.16] vs [16.04 ± 3.05], and [28.08 ± 4.70] vs [20.14 ± 4.74]%, P < 0.01), the percentage of grade a + b sperm ([30.10 ± 5.07] vs [26.21 ± 3.96], [38.08 ± 5.64] vs [30.07 ± 4.80], and [48.04 ± 6.49] vs [35.28 ± 4.77]%, P < 0.01), sperm motility ([42.04 ± 4.86] vs [40.29 ± 4.19], [52.05 ± 5.58] vs [48.03 ± 4.40], and [65.03 ± 5.13] vs [56.67 ± 4.99]%), the FSH level ([7.75 ± 1.38] vs [7.20 ± 1.17], [10.83 ± 1.23] vs [9.10 ± 1.32], and [14.22 ± 0.84] vs [12.06 ± 1.45] IU/L, P < 0.01), the LH level ([10.05 ± 1.68] vs [9.18 ± 1.54], [13.96 ± 1.68] vs [11.99 ± 1.71], and [19.01 ± 2.42] vs [15.86 ± 2.08] IU/L, P < 0.01) and the T level ([19.19 ± 192] vs [18.34 ± 1.79] [21.06 ± 1.63] vs [20.06 ± 1.56], and [24.63 ± 1.06] vs [22.03 ± 1.49] nmol/L, P < 0.01). The pregnancy rate in the patients' spouses was significantly higher in the trial than in the control group at 4, 8, and 12 weeks (1.92 vs 0.69, 4.81 vs 3.47, and 11.54 vs 8.33%, P < 0.01). There were no statistically significant differences in drug tolerance between the two groups (P > 0.05). No obvious adverse reactions were observed.

CONCLUSIONQilin Pills combined with clomiphene can evidently improve the seminal quality and hormone level of oligoasthenospermia patients with no obvious adverse events. However, its long-term efficacy and tolerance deserve further clinical investigation.
