Wether cancer patients can re-adapt to life or not after experiencing tremendous frustration is the focus of tumor care nowadays.Since the measurement methods and outcome indexes of cancer patients adaptation level are different,adaptation related factors and predictors are controversial and there is not yet a unified opinion.Currently,it is thought that demographic information (like age,gender,education),disease-related information (like physiological indicators,treatment options,body image and sex) are closely related to cancer patients adaptation after stress.However there are huge differences among the extents and effects.

Objective To observe the effect of the modified Yulin Decoction on improving the living quality of patients with yang-deficiency of the spleen and kidney of premature ovarian failure. Methods One hundred and twenty-seven patients were divided into experimental group (80) and control group (47) by non-randomized noninferiority comparative study. The experimental group was treated with modified Yulin Decoction daily orally once a day. The control group was treated with oral estradiol valerate and progesterone cycle. Two groups received continuous medication for 21 d, and treatment interval was 5 d. Three cycles of treatment were set as one course, and treated for 2 courses. The SF-36 scale was used to calculate the total scores and scores of eight dimensions before and after treatment. Results Before treatment, there was no significant difference (P>0.05) in the scores of SF-36 dimensions (except somatic pain) and total score between the two groups. Compared with before treatment, the score and total score of SF-36 in the experimental group increased (P<0.05, P<0.01). The mental health score of the control group was higher than that of before treatment (P<0.05, P<0.01). After treatment, there was statistical significance in the two dimensions of vitality and mental health in the two groups (P<0.05). There were significant differences (P<0.01) in the total score and scores of SF-36 physiological function, physical pain, general health, vigor, social function, emotional function and mental health between the two groups. Conclusion Modified Yulin Decoction can improve the living quality of patients with yang-deficiency of the spleen and kidney of premature ovarian failure.

Objective To evaluate the role of μ-opioid receptor (MOR) in attenuation of bone cancer pain by anti-nerve growth factor (anti-NGF) in rats. Methods Part Ⅰ Sixty female SD rats weighing 200-220 g were randomly divided into 4 groups (n = 15 each): sham operation group (group S), sham operation + anti-NGF group (group SN), bone cancer pain group (group P) and bone cancer pain+ anti-NGF group (group PN) . Bonecancer was induced by intra-tibial inoculation of 1 × 105 Walker 256 breast cancer cells in group P and PN. Group S and SN received injection of PBS 10 μl. APE 10 catheter was inserted at L2,3 interspace into the epidural space 13 days after cancer cell inoculation. Three days after the catheter was successfully placed, group SN and PN received intrachecal (IT) injection of anti-NGF 10 μg (in normal saline (NS) 10 μl) and group S and P IT injection of NS 10 μl twice a day for 5 consecutive days. The number of spontaneous flinches (NSF), paw withdrawal latency (PWL) and paw withdrawal threshold (PWT) were measured before and 13, 16, 18, 21 day after cancer cell inoculation. The animals were sacrificed at 21 day after cancer cell inoculation and the spinal cord dorsal horn and dorsal root ganglion were removed for determination of MOR and MOR mRNA expression. Part Ⅱ Thirty female SD rats weighing 200-220 g were randomly divided into 2 groups (n = 15 each): bone cancer pain + anti-NGF group (group PN) and bone cancer pain + naloxone + anti-NGF group (group PNN). Bone cancer was induced by intratibial inoculation of 1 × 105 Walker 256 breast cancer cells. APE 10 catheter was inserted at L2-3 interspace into the epidural space 13 days after cancer cell inoculation. Three days after the catheter was successfully placed,group PN received IT injection of anti-NGF 10 μg (in NS 10 μl) and group PNN IT injection of naloxone 10μg (in NS 25 μl) and 0.5 h later IT injection of anti-NGF 10 μg (in NS 25μl) twice a day for 5 consecutive days. NSF,PWL and PWT were measured before and 13, 16, 18, 21 days after cancer cell inoculation. Results Part ⅠCompared with group S, no significant change was found in NSF, PWL and PWT in group SN, and in MOR and MOR mRNA expression in group SN and PN (P ＞ 0.05), NSF was significantly increased, PWL shortened, PWT decreased at 13-21 days after inoculation in group P and PN, and MOR and MOR mRNA expression was down-regulated in group P (P ＜ 0.05 or 0.01). Compared with group P, NSF was significantly decreased, PWL prolonged, PWT increased, MOR and MOR mRNA expression was up-regulated in group PN at 18-21 days after inoculation (P ＜ 0.05 or 0.01). Part Ⅱ Compared with group PN, NSF was significantly increased, PWL shortened, PWT decreased at 18-21 days after inoculation in group PNN (P ＜ 0.05 or 0. 01). Conclusion The mechanism by which anti-NGF attenuates bone cancer pain in rats is related to the activation of MOR.

Objective To investigate the protective effect of total flavones of Artemisia capillaris Thunb.on acute hepat-ic injury in rats. Methods Rats were randomly divided into blank control group,model control group, Yinzhihuang group,and groups of total flavones of Artemisia capillaris Thunb.(low,medium and high dose) in terms of 7-day different treatments.All rats except those in the blank control group were administrated with D-galactosamine hydrochloride ( 500 mg?g-1 , ip ) once at the sixth day.Then,concentrations of ALT and AST were detected 48 h later,and the liver samples were collected from each group for pathological examination. Results The serum ALT and AST in high-dose group of total flavones of Artemisia capillaris Thunb. was [(189.2±112.9) and (231.7±149.9) U?L-1],respectively,significantly lower than those in model control group ALT [(391.9±181.3) U?L-1] and AST [(403.9±133.8) U?L-1].Fragmented necrosis,fatty degeneration,inflammatory cells infil-tration and acidophilic degeneration of hepatic cells were improved to varying degrees in groups of total flavones of Artemisia capil-laris Thunb.compared with model control group.Fragmented necrosis of liver cells and steatosis occurred in 20 and 19 rats,respec-tively,in the model control group,while those appeared in 1 and 2 rats,respectively,in high-dose group of total flavones of Artemi-sia capillaris Thunb.. Conclusion Total flavones of Artemisia capillaris Thunb. are effective in protecting D-galactosamine hydrochloride-induced acute hepatic injury in rats.

BACKGROUND:Posterior lumbar interbody fusion can thoroughly decompress the central canal, which is the common surgical technique for the central type of lumbar disc herniation with intervertebral instability at low lumbar segment. However, due to the regular traction on dural sac and nerve root in the operation, lower limb radicular pain in the early stage is inevitable. OBJECTIVE:To evaluate the effect of local use of gelatin sponge containing prednisolone acetate around the nerve roots after posterior lumbar interbody fusion on lower limb radicular pain. METHED:Sixty-three cases of lumbar disc herniation with degenerative instability were devided into treatment group (n=21) and control group (n=42) based on the type of implants. Gelatin sponge containing prednisolone acetate was implanted into patients in the treatment group after posterior lumbar interbody fusion, while pure gelatin sponge was implanted into patients in the control group. RESULTS AND CONCLUSION:Compared with the control group, radicular pain in the treatment group was significantly relieved within 1 week after surgery. The visual analog scale score and Oswestry disability index score were similar between the two groups. There were three cases of radicular pain recurrence in the control group, but no incision infection and epidural hematoma after surgery in both two groups. In conclusion, local use of gelatin sponge containing prednisolone acetate around the nerve roots can significantly relieve lower limb radicular pain in the early stage after posterior lumbar interbody fusion in lumbar disc herniation, contributing to early rehabilitation exercise and patient satisfaction outcomes.

By combing differe nt modelin g factors and evaluation indicators of experimental animals of polycystic o-vary syndrome (PCOS), application scope, advantages and disadvantages were analyzed among various kinds of animal models, in order to screen models of etiology and pathogenesis in traditional Chinese medicine (TCM). Through the collection of 77 Chinese literatures published since 1979, the database on PCOS of modeling factors (i.e., animal species, age, modeling reagent and dose, etc.) and evaluation indicators (i.e., ovarian morphology and hormone levels) were established, analyzed and summarized. The results showed that the experimental PCOS models established by researchers both at home and abroad included androgen method, combination method of androgen with HCG, combi-nation method of progestrone with HCG, estrogen method, aromatic cyclase inhibitor method, combination method of HCG with insulin, combination method of androgen with insulin, insulin method, and etc. The SD and Wistar rats at the age of 3-50 days were commonly used. Chemicals, such as dehydroepiandrosterone (DHEA), testosterone propi-onate, sodium prasterone sulfate, dihydrotestosterone (DHT), levonorgestrel, estradiol valerate, letrozole, insulin and HCG were chosen to build the animal models. The evaluation indicators included ovarian morphology, the total num-ber of follicles at different levels, sex hormones (E2, P, T, FSH, LH) and insulin resistance (IR) index (FINS, FPG, HOMA). It was concluded that each modeling method described above had its own advantages and disadvantages, which cannot completely simulate clinical onset process of PCOS patients. Researchers should choose appropriate reagent and evaluation index according to different purpose. DHEA, DHT slow-release, progesterone combined with HCG modeling methods are more suitable for the study of the role of IR in the pathogenesis of PCOS. Kidney-defi-ciency and dampness-phlegm is fundamental etiology and pathogenesis of obese type of PCOS. DHEA method, com-bination method of levonorgestrel with HCG, aromatic cyclase inhibitor method conformed obese type of PCOS. The evaluation indicators included body weight, sex hormones, IR index and ovarian morphology. The method of kidney-tonifying and phlegm-reducing was often used in the treatment of obese type of PCOS in the clinical practice.

Objective:To investigate the effects of Helicobacter pylori on NLRP3 inflammasomes activation in THP-1 ( human monocytic cell line) -derived macrophages and evaluate the role of ROS.Methods:H.pylori strain SS1 was co-cultured with the THP-1-derived macrophages at a multiplicity of infection (MOI) of 1∶100 based on trial results with different MOIs (ratios of THP-1 cells to bacteria ranging from 1∶25 to 1∶200).The co-culture supernatants and THP-1 cells were collected at various time points (3 h,6 h,12 h,24 h) and cytokine production was quantitated using ELISA analysis.The generation of intracellular ROS was detected by FCM,and the mRNA transcript levels of NLRP3 and caspase-1 were measured by Real-time PCR.Western blot was employed to analyze the expression of active caspase-1 subunit ( p10).Then we observed the inhibitory effects of NAC and siRNA specific for NLRP3 on the ex-pression of NLRP3 inflammasome-related components and the secretion of cytokines induced by H.pylori.Results:We found that H.pylori SS1 induced IL-1βand IL-18 production in human acute monocytic leukemia cell line THP-1 in a time-and dose-dependent manner.We further showed that H.pylori could induce the mRNA expressions of NLRP3 and caspase-1 in THP-1 cells.Moreover, release of IL-1βand IL-18 from H.pylori-infected THP-1 cells was suppressed by the ROS scavenger NAC,which was an agent known to inhibit NLRP3 inflammasome formation.NAC administration also resulted in a significant decrease in the level of H.pylori-induced caspase-1 protein expression in THP-1 cells.Additionally,secretion of IL-1βand IL-18 in response to H.pylori infection was remarkably reduced by NLRP3-siRNA.Conclusion:The induction of IL-1βand IL-18 secretion by H.pylori strain SS1 in THP-1 cells could be mediated through activation of NLRP3 inflammasome via ROS signaling pathway, which may be involved in the host innate immune defence and the pathogenesis of the bacteria.
