This study was aimed to observe effects of qi-stagnation and blood-stasis pattern of primary dysmenorrhea (PD) treated by Huo-Xue Li-Qi Zhi-Tong (HXLQZT) decoction combined with acupuncture. A total of 130 PD patients, which were selected from January 2011 to January 2014 at the Chongqing Academy of Traditional Chinese Medicine, were randomly divided into the treatment group and the control group, with 65 cases in each group. The control group was treated with ibuprofen sustained release capsules and the treatment group was given HXLQZT decoction combined with acupuncture. After the treatment of 3 menstrual cycles, indexes were observed from aspects including visual analogue score (VAS), PGF2a, PGE2, PGF2a/PGE2, clinical efficacy and relapse circumstance before and after treatment in two groups. The results showed that compared with pretreatment, there were obvious decreased VAS in both the treatment group and the control group (P<0.05), decreased PGF2a, increased PGE2 content, and obvious decreased PGF2a/PGE2 ratio (P < 0.05). Compared with the control group, the cure rate and the total efficiency of the treatment group were significantly increased (P < 0.05). The VAS was significantly decreased in the third menstrual cycle after treatment (P < 0.05). The ratio of PGF2a/PGE2 was significantly decreased (P < 0.05). In the end of 6-month, 9-month and 12-month treatment, relapse rates of the treatment group were significantly lower than those of the control group (P<0.05). It was concluded that HXLQZT decoction combined with acupuncture can regulated the plasma content of PGF2a and PGE2 and reduce the relapse rate among PD patients. It had obvious effect on PD patients with superior treatment effect compared to western medicine treatment. Therefore, it was worthy of a promotion.

A total of 120 cases were randomly divided into the acupuncture combined with traditional Chinese medicine (TCM) group, TCM group, and acupuncture group, with 40 cases in each group. The TCM group was given oral administration with QRLSHY decoction. The acupuncture group was given acupuncture on SP6-Sanyinj iao and RN6-Qihai . The acupuncture combined with TCM group was given oral administration with QRLSHY decoction and acupuncture treatment. The treatment course of each group was 2 months. The ob-servation was made on clinical efficacy, clinical symptoms, body signs, changes of laboratory indexes, and relapse rate of three groups. The results showed that compared with pretreatment, the total effective rate of the acupunc-ture combined with TCM group, TCM group and the acupuncture group was obviously increased after treatment (P< 0 . 05 ) . Compared with pretreatment , the clinical symptoms and body signs such as abdominal pain , abdominal bulge, backache, leucorrhea increased, dysmenorrhea, menstrual disorders, lassitude, appendix thickening, pelvic tenderness, and pelvic mass were significantly improved in all three groups (P < 0.05). After treatment, clinical symptoms and body signs of the acupuncture treatment with TCM group had more obvious advantages than the TCM group and the acupuncture group ( P < 0 . 05 ) . Compared with pretreatment , the cervical or vaginal mucus pu-rulent secretion, vaginal wet film mirror of white blood cells, white blood cell count, absolute neutrophil count of all three groups were significantly improved ( P < 0 . 05 ) . After treatment , the acupuncture combined with TCM group had more obvious advantages than the TCM group and acupuncture group ( P < 0 . 05 ) . The relapse rate of the acupuncture combined with TCM group was obviously lower than the TCM group and the acupuncture group 6 months, 9 months, and 12 months after treatment (P < 0.05). It was concluded that QRLSHY decoction combined with acupuncture had obvious clinical curative effect in the treatment of chronic PID with syndrome of damp-heat and blood-stasis. The effect was better than only use TCM or acupuncture. It is worth of promoting in the clini-cal practice .

Objective To investigate the expression pattern of skeletal muscle specific miR-206,myogenesis related myoD which change with time in dcnervated muscle atrophy rats.Methods From June,2015 to January,2016,40 SPF sprague-dawley rats were equally classified into 5 groups randomly according to standard settled before,5 groups were separately defined as denervated 0d group,denervated 1d group,denervated 7d group,denervated 14d group,and denervated 28d group.Each group contained 8 rats.The rats atrophy models were established by cutting sciatic never on left side.According to the different denervated time,the gastrocnemii on both sides were obtained under anesthesia,respectively.The wet weight ratio of two compared gastrocnemii were measured,and the gastrocnemii transection was observed by HE stain,measured the expression of myoD protein by western blot,obtained the expression of miR-206,myoD mRNA by qPCR.Results According to our study on rats denervated atrophy models,the wet ratio of compared gastrocnemius would decrease rapidly,by HE stain,decease of cross sectional area in muscle fiber was observed as well as degeneration.Collagen fibers hyperplasia appeared and increased with time change.Wet ratio and transaction aera ratio of group Od,1d,7d,14d,28d were 0.99±0.04,0.92±0.07,0.68±0.11,0.39±0.06,0.27±0.07 and 0.99±0.02,0.96±0.04,0.51±0.09,0.34±0.08,0.23±０.03 respectively,difference between experimental groups and control group were statistically significant (P＜ 0.05),the differences between each experimental groups were also statistically significant (P＜ 0.05).After qPCR test of miR-206,myoD mRNA expression,it was found that their expression patterns were similar,miR-206,myoD mRNA increased at first and would reach the expression peak at the 7 th day,after that their contents decreased but still higher at the 14th day when compared with that at the 1 st day.Their expression of group 0d,1 d,7d,14d,28d were 0.24±0.06,0.34±0.04,0.68±0.04,0.49± 0.07,0.25±0.03 and 0.41 ±0.06,0.49±0.09,0.93±0.06,0.66±0.03,0.39±0.04,respectively.All experimental groups were statistically significant different when compared with 0d group except 1d group (P＜ 0.05),the differences between each experimental groups were also statistically significant(P＜ 0.05).The protein expression of myoD was also measured by western blot test,which showed nearly the same expression pattern as the mRNA expression pattern.After injury,the protein expression increased and reached the expression peak at the 7th day.The relative expression of myoD of group 0d,1d,7d,14d,28d measured by grey ratio were 1.03±0.05,1.06±0.06,1.42±0.10,0.66±0.13,0.24±0.07,respectively.The difference between experimental groups and control group were statistically significant (P ＜ 0.05),the differences between each experimental groups were statistically significant (P ＜ 0.05) as well.Conclusion The degree of muscle denervation atrophy was related to the denervated duration in rats.The expression regulation of miR-206 and myoD in gastrocnemius was similar during the muscle denervation atrophy,which suggesting having internal relationship between miR-206 and myoD.

AIM and METHODS: The ratio of mitochondrial DNA (mtDNA) deletion was measured to find the relationship between mtDNA deletion and aged learning and memory deficit. The aged rats were divided into two groups, aged learning and memory deficit group and aged learning and memory normal group. The ratio of mtDNA deletion was measured by dilution polymerase chain reaction. RESULTS: There are deleted mtDNA (about 4834 bp) in the cerebral cortex, hippocampus and cerebellum of both young and aged rats. The ratios of deleted mtDNA were similar in the cerebral cortex,hippocampus and cerebellum of young rats (about 0.00018%). The ratio mtDNA of aged learning and memory normal rats had increased by five-fold in the cerebral cortex and hippocampus, or one-fold in the cerebellum over young rats. The ratio of aged learning and memory dificit rats had increased by one-fold in the cerebral cortex or 0.8-fold in the hippocampus or two-fold in the cerebellum over aged learning and memory normal rats.CONCLUSIONS: There was really the increase of mtDNA in aging rat brain. And this increase was double in amount in aged learning and memory deficit rats compared to the normal learning and memory aged rats. It is suggested that the mtDNA deletions in the brain regions associated with learning and memory may be contributed to the cellular and molecular mechanism of learning and memory deicit with aged rats.

Objective To analyze the clinical,endoscopic,and pathological features of aged patients with ulcerative colitis and the difference between the aged and non-aged patients. Methods The clinical,endoscopic,and pathological data from 349 ulcerative colitis patients admitted in Huadong Hospital from January 2000 to December 2008 were reviewed and analyzed retrospectively. The patients were divided into two groups: aged group (≥60 years) and non-aged group (0.05) between the two groups. The disease of aged patients was less severe than that of the non-aged patients (P0.05). The occurrence of dysplasia in the aged patients was higher than that in the non-aged patients (P

The effects of human fetal hepatic stimulator substance (h-HSS) and liver cytosol (h-FLC) on the survival rate,the intensity of liver damage,and liver regeneration in rats with liver necrosis induced with D-galactosamine were observed.The physico-chemical properties of h-HSS were preliminarily determined.It was found that both h-HSS and H-FLC could markedly increase the.survival rate of the rats with toxic liver necrosis,significantly decrease the serum level of ornithine carbamoyl transferase and mitochondria aspartic trans-aminase,improve the hepaplastin activity,and elevate the incorporation rate of 3H-thymidine with liver DNA.h-HSS was stable after heated to 95℃ for 30 minutes,and sensitive to trypsin treatment.It demonstrated one major band at 15 000 daltons and 3 minor ones at 24 000,34 000,and 40 000 daltons respectively on sodium dodecyl sulfate-polyacrylamide gel electrophoresis.The relative content of the major band was 47.57%.

Objective To explore the feasible approach for establishment of a liver cancer model induced by N-nitrosodiethylamine(DENA)with Sprague-Dawley rat,and to provide ideal animal model for imaging diagnosis and interventional therapy.Methods One-hundred and forty male SD rats were administrated with 0.95 g/L DENA for 10 weeks,and MRI was performed for inspecting pathological changes of rat livers on the following week.When the liver tumor was proved then the rat will be the candidate for sequential procedures,otherwise the animal continued under observation until next MRI examination after 4 weeks.DSA was done in 64 rats'for detecting blood supply of liver tumors.Animals were sacrificed with an overdose of chloral hydrate,The representative tumor tissues were fixed in 10% formalin and 2.5% glutaraldehyde for light and electron microscopy analysis respectively.Alpha fetoprotein(AFP) and hepatocyte were assaied by immunohistochemistry technique in order to identify intrinsic trait of the harvested tumors.Results The earliest induced tumor was detected on 11th week and the latest was on 20th week by MRI,and the median period was 13.9 weeks.Tumor size ranged from 2 mm to 40 mm in diameter. The rate of single and multi-induced tumor was 9.7%(7/72)and 90.3%(65/72),respectively.87.7% (57/65)" of the induced multiple tumors was with hepatocirrhosis and 18.1% of these tumors combined with extrahepatic neoplasm or metastasis.Plenty blood supply was proved by DSA in most of those tumors. Tumors not only derived from hepatocyte but also manifested positive expression of AFP.Histological types of these tumors include hepatocellular carcinoma(HCC)(92.0%,66/72),intrahepatic cholangiocarcinoma (ICC)(4.0%,3/72),and combined HCC and ICC(4.0%,3/72),respectively.Electro-microscope analysis indicated that cytoplasm and organelle of induced tumors were abnormal distinctly compared with those of non-carcinomatous cells.Conclusion DENA can induce ideal rat liver cancer as a feasible animal model,MRI is the best approach for scrutinizing pathological changes of rat livers during induced period.

Objective To compare the sensitivity and specificity of interferon-gamma release assay(IGRA) in the Tibetan and Han patients with pulmonary tuberculosis(TB),and to investigate its clinical application value for screening Tibetan patients with pulmonary TB.Methods Sixty-four Tibetan cases of pulmonary TB,41 Tibetan cases of non-pulmonary TB,40 Han cases of pulmonary TB and 38 Han cases of non-pulmonary-TB in our hospital from April 2013 to April 2015 were selected and performed IGRA.T cells infected by mycobacterium tuberculosis were detected by ELISA.The difference between Tibetan abd Han nationalities was compared.The clinical value of IGRAfor screening Tibetan patients with pulmonary TB was evaluated by calculating the statistical indicators.Results The sensitivity,specificity,positive predictive value and negative predictive value of IGRA for diagnosing Tibetan pulmonary TB were 90.62%(58/64),80.49%(33/41),87.88%(58/66) and 84.62%(33/39) respectively,which for diagnosing Han patients with pulmonary TB were 92.50%(37/40),84.21%(32/38),86.05%(37/43) and 91.43%(32/35) respectively.The sensitivity and specificity of IGRA for diagnosing Tibetan and Han pulmonary TB had no statistical difference(χ2=0.005,P=0.944;χ2=0.018,P=0.893).Conclusion IGRA has high value for early diagnosis of Tibetan pulmonaty TB and is conducive to screening of early pulmonary TB.

Objective To investigate the roles of theaflavins(TFs) in airway mucus hypersecretion induced by human neutrophil elastase(HNE). Methods Human lung adenocarcinoma cell A549 was stimulated by HNE for mucus hypersecretion,and TF monomers(TF1,TF2 and TF3) were used for intervention.The effects of TF monomers on viability of A549 cells were examined by MTT method.After the effective doses of TFs were determined,A549 cells were divided into 4 groups for experiment.In control group,A549 cells were cultured with serum-free medium.In HNE treatment group,A549 cells were treated with HNE(50 nmol/L) for 24 h.In TF monomer intervention groups,A549 cells were pre-treated with TF1,TF2 or TF3(50,100 or 200 ?g/mL) for 24 h,and were then treated with HNE for another 24 h.In AG1478 intervention group,A549 cells were pre-treated with AG1478(5 ?mol/L),an epidermal growth factor receptor blocker for 30 min,and were then treated with HNE for another 24 h.The changes in mucin(MUC) after treatment by different doses of TF1,TF2 and TF3,and by TF3(200 ?g/mL) for different time(12 h,24 h and 36 h) were detected.The changes in MUC5AC mRNA expression and MUC5AC protein expression were detected by RT-PCR and ELISA,respectively. Results The MUC5AC mRNA expression and protein expression in HNE treatment group were significantly higher than those in control group(P
