AIM: To evaluate the effect of probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment for the treatment of chronic dacryocystitis.METHODS: For 127 cases (129 eyes) of chronic dacryocystitis, first the pyoid secretion gathered in the lacrimal sac was dashed out, and some TobraDex was injected in the middle of the lacrimal passage once per day, repeated for several times. The lacrimal passage was probed when the secretion of lacrimal sac disappeared essentially. The lacrimal passage and immit TobraDex eye ointment was used once every two days, repeated for 3-4 times.RESULTS: In 126 cases (128 eyes) the lacrimal passage was dredged. Only one case (1 eye) the youthful patient did not recover for the opening ectopia of lacrimonasal duct.During the 3mo-1a random visit the chronic dacryocystitis did not recrudesce in the cases of lacrimal passage dredging.CONCLUSION: It is simple and safe to use the probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment to treat the chronic dacryocystitis. This method has good curative effects and can keep the normal physiological structure of lacrimal passage. It does not need any expensive medical equipment and cost less, therefore is advisable for patients.

OBJECTIVETo observe the analgesic effect and safety of acupuncture-anesthetic composite anesthesia (AACA) in hysteroscopic surgery.

METHODSTotally 93 patients undergoing hysteroscopic surgery were randomly assigned to the intravenous anesthesia group (A group, 30 cases), the AACA group (B group, 32 cases), and the acupuncture combined with intravenous anesthesia group (C group, 31 cases). Patients in Group A were anesthetized by sufentanil combined propofol. Those in Group B were anesthetized by sufentanil combined acupuncture. Those in Group C were anesthetized by sufentanil, propofol combined acupuncture. Yinlian and Ququan (LR8) were needled for patients in Group B and C. The peri-operative mean arterial pressure (MAP), heart rate (HR), and oxygen saturation (SpO2), the surgical time, the recovery time, the sufentanil and propofol dosages, adverse anesthesia reactions were observed. Meanwhile, the OAA/S score, Ramsay sedation score, and Visual Analogue Score (VAS) were also measured.

RESULTSCompared with Group A and C, patients in Group B were awake, with obvious increased OAA/S score (P < 0.01). Ramsay sedation score was significantly lower (P < 0.01).The MAP and HR were elevated (P < 0.05). The patient case of SpO2 less than 85% during the operation decreased (P < 0.05). The incidence of postoperative dizziness was reduced (P < 0.05). Compared with Group A, the propofol consumption decreased in Group C (P < 0.05). There was no statistical difference in the operation time, the sufentanil dosage, VAS score, the incidence of postoperative nause- a and vomiting among the three groups (P > 0.05).

CONCLUSIONSThe patients were awake in AACA. The intraoperative sedation was better than that obtained by intravenous anesthesia. But the analgesic effect was similar to that obtained by intravenous anesthesia.

Ribavirin is a broad-spectrum antiviral agent and glycyrrhizin has activities of anti-inflammation, immunoregulation and anti-viral infections. To enhance antiviral efficacy and weaken side-effects of ribavirin, antiviral effects of the combination of glycyrrhizin and ribavirin were studied in the present study. Firstly, a mouse model of viral pneumonia was established by inoculation of influenza H1N1 virus. Protective effects of glycyrrhizin and ribavirin used alone or in combination against H1N1 virus infection in mice were evaluated based on the survival rate, lung index and virus titer in lungs of mice. Results showed that the combination of glycyrrhizin and ribavirin significantly inhibited the lung consolidation with a 36% inhibition ratio on the lung swell of infected mice. The combination of the two drugs exhibited synergetic effects on survival of infected mice. The combination of 50 mg · kg(-1) · d(-1) glycyrrhizin and 40 mg · kg(-1) · d(-1) ribavirin resulted a 100% protection for infected mice with a synergetic value of 36, which was significantly higher than the control group and each drug alone. This combination also resulted a significant drop of lung virus titer (P < 0.01), as well as inhibition on the production of proinflammatory cytokines IL-6 (P < 0.01), TNF-α (P < 0.01) and IL-1β (P < 0.05) induced by virus infection compared to the control. The treatment of ribavirin plus glycyrrhizin was more effective in influenza A infection in mice than either compound used alone, which suggested a potential clinical value of the combination of the two agents.

OBJECTIVETo establish a new method for the determination of fangchinoline and tetrandrine in Stephania tetrandra and Fengtongan capsule by noanqueous capillary electrophoresis.

METHODSeparation was carried out in an uncoated fused capillary (50 cm x 75 microm i.d.) with a running buffer containing 50 mmol x L(-1) ammonium acetate, 1.0% acetic acid and 20% acetonitrile in methanol. A separation voltage of 20 kV and a UV detector wavelength at 214 nm were adopted. Sample was introduced from the anode.

RESULTThe calibration ranges were 1.00, 500 mg x L(-1) for both analytes. Under the optimum conditions, the relative standard deviation (RSD, n = 6) for the migration time of each analyte were 0.09%, 1.9% (intra-day) and 0.63%, 1.9% (inter-day); The RSD for the peak area of each analyte were 0.45%, 5.9% (intra-day) and 2.3%, 5.6% (inter-day), respectively. The contents of the analytes were determined easily with average recoveries 102% for fangchinoline and 105% for tetrandrine in S. tetrandra and 94.6% for fangchinoline and 98.7% for tetrandrine in Fengtongan capsules, respectively.

CONCLUSIONThe proposed method is simple, rapid, accurate and higher repeatable, and can be used to control of the quality of S. tetrandra and Fengtongan capsules.

OBJECTIVETo investigate the effects of Zhikepingon the oxyradical andintercellular adhesion molecule-1 (ICAM-1) of experimental early atherosclerosis.

METHODThe model of SD rat early atherosclerosis was induced by cholesterol diet. The suspension of Zhikeping and simvastatin were administered intragastrically, respectively. After 10 weeks, the serum lipids, superoxide dismutase (SOD) and maleic dialdehyde (MDA) were detected by automatic biochemistry analyzer. ICAM-1 and its expression of mRNA in aortic wall were detected- by immunohistochemistry and RT-PCR, respectively. Aortic histomorphology was cbserved by HE stainning.

RESULTThe results showed that the serum lipids, superoxide dismutase (SOD) and maleic dialdehyde (MDA) of treated groups were obviously improved as compared with those of the control group. The tissue pathological damage was improved indifferent degree, and ICAM-1 and its expression of mRNA was decreased obviously.

CONCLUSIONIt is suggested the mechanism of anti-atherosclerosis of Zhikeping have close relationship with the function of its anti-oxidizing and anti-adhesiveness that can protect aortic endothelial cell.

OBJECTIVETo study the association between cholesteryl ester transfer protein (CETP) gene polymorphism and insulin resistance in type 2 diabetes.

METHODSCETP-TaqIB gene was genotyped with polymerase chain reaction-restriction enzyme fragment polymorphism analysis in 108 patients with type 2 diabetes and in 60 normal controls. Plasma lipids, fasting insulin, insulin sensitivity index and insulin resistance index were determined in 108 patients with type 2 diabetes.

RESULTSThe distribution of CETP-TaqIB genotypes and B1B2 allele frequency in the patients with type 2 diabetes were similar to that in general population. High density lipoprotein cholesterol (HDL-C), apolipoprotein A1(apoA1) and insulin sensitivity index (ISI) levels were significantly higher in B2B2 genotype than in B1B1 genotype. Fasting insulin (FINS) and Homeostasis model assessment-insulin resistance (HOMA-IR) levels were significantly lower in B2B2 genotype than in B1B1 genotype. No significant differences in triglyceride (TG), total cholesterol(TC),low density lipoprotein cholesterol (LDL-C), apolipoprotein B (apoB) levels were observed among different CETP-TaqIB genotype groups. By multivariate analysis, the determinants of ISI and HOMA-IR were body mass index (BMI), TC, HDL-C and CETP-TaqIB genotype.

CONCLUSIONThe CETP-TaqIB genotype is independently associated with insulin resistance and lipid metabolism. It may be an important risk factor of insulin resistance in type 2 diabetes.

Cellular senescence is one of the important steps against tumor. This study was to observe the characteristics of boningmycin induced senescence of human tumor cells. MIT method and clone formation assay were used to detect the growth-inhibitory effect. Cellular senescence was detected with senescence-associated beta-galactosidase staining. Cell cycle distribution and accumulation of intracellular reactive oxygen species (ROS) were analyzed with flow cytometry. Protein expression was detected by Western blotting. The results showed that the growth-inhibitory effect of boningmycin was obviously stronger on human oral epithelial carcinoma KB cells than that on non-small cell lung cancer A549 cells. Comparison to the similar action of doxorubicin, that boningmycin induced the features of cellular senescence in both cell lines, its due to the arrest at G2/M phase and an increase of ROS level. The molecular senescence marker P21 increased significantly after boningmycin treatment at a dosage of 0.1 micromol x L(-1), whereas a higher concentration of it induced apoptosis. The results indicated that cellular senescence induced by boningmycin was one of its mechanisms in tumor suppression.

OBJECTIVETo investigate the protective effects of the natural medicinal monomer isopsoralen (ISR) with estrogenic activity against oxidative damage in human lens epithelial cells B3 (HLE-B3) caused by hydrogen peroxide (H(2)O(2)) and to pursue the possible mitochondrial proteomic regularity of the protective effects.

METHODSHLE-B3 cells were treated with H(2)O(2) (300 μ mol/L), β-estradiol (E(2): 10(-8) mol/L) and H(2)O(2), ISR (10(-5) mol/L) and H(2)O(2), or left untreated. Altered expressions of all mitochondrial proteins were analyzed by protein array and surfaceenhanced laser desorption ionization time of flight mass spectrometry (SELDI-TOF-MS). The mass/charge (m/z) ratios of each peak were tested by the Kruskal-Wallis rank sum test, and the protein peak value of the m/z ratio for each treatment by pair comparison was analyzed with the Nemenyi test.

RESULTSH(2)O(2) up-regulated the expressions of two protein spots (with m/z of 6532 and 6809). E(2) mitigated the oxidative damage, and the expression of one protein spot (m/z 6532) was down-regulated. In contrast, ISR down-regulated both of protein spots (m/z 6532 and 6809).

CONCLUSIONSISR could effectively inhibit H(2)O(2)-induced oxidative damage in HLE-B3 cells. The protein spot at m/z of 6532 might be the target spot of ISR against oxidative damage induced by H(2)O(2).
