Method for measuring interleukin 1 ( IL -1 ) and effects of total glucosides of paeony(TGP) on IL -1 production were studied. The results showed that the best concentration for LPS -induced IL-1 production of M s in rats was 8mg/L, the best dilution for IL-1 of LPS-induced M s production was 1 : 90. TGP ( 0 .5 - 12 .5mg/L ) enhanced LPS-induced IL -1 production in a concentration dependent manner, but diminished in the higher concentration of TGP ( 62 .5~l25mg/L ) , the concentration-effect curve seems to be bell-shaped. The data suggested that TGP had two-sided regulatory effects on LPS -induced IL production of M s in rats.

Effects of total glucosides of paeony ( TGP) on interleukin2 ( IL-2 ) production were studied with lL-2-dependent marine splenic lymohocytes. The results showed that IL-2 production by splenocytes was enhanced with low concentration of TGP (0.5-12.5 mg/L) , and diminished over the rang of 12.5-62.5mg/L. The concentration-effect curve seems to be bell-shaped. The data suggested that TGP hap two-sided regulatory effects on IL 2 production by splenocytes.

Objective To study the effects of ginkgo biloba extract(GBE)on c-reactive protein(CRP) and tumor necrosis factor-α(TNF-α)in serum and alveolar lavage fluid(BALF)from rats with chronic obstructive pulmonary disease(COPD). Methods 90 rats were randomly divided into groups A,B,C,D,E and F. There were 15 rats in each group. The rat model of COPD were established in groups B,C,D,E and F. Groups C and D were given intraperitoneal injections with GBE from day l to day l4 and day 29 to day 42. Groups E and F weregiven intraperitoneal injections with erythromycin from day l to day l4 and day 29 to day 42. After the end of experi-ment ,the contents of CRP and TNF-α in serum and BALF were detected in all groups. Results The contents of CRP and TNF-α in the serum and the BALF were markedly lower in groups C,D,E and F than in group B (P<0.05);and the contents of CRP in the serum and the BALF and TNF-αin the BALF were lower in groups C, E and F than in group D(P<0.05). Conclusions GBE can inhibit the airway and systemic inflammatory response in COPD rats. Early intervention is more effective.

Objective To observe the effect of Fufei Gushen Decoction on the BODE index, an index for body mass index(BMI), airflow obstruction, dyspnea, and exercise capacity, in severe and extremely severe chronic obstructive pulmonary disease (COPD) patients with lung-kidney deficiency interweaved with phlegm and blood stasis at stable stage. Methods Eighty qualified COPD patients were randomly divided into treatment group and control group, 40 cases in each group. Both groups were given inhalation of Seretide (Salmeterol Xinafoate and Fluticasone Propionate Powder for inhalation) , and the treatment group was given oral use of Fufei Gushen Decoction additionally. The treatment for the two groups lasted for 3 months. Before and after treatment, BMI, the percentage of forced expiratory volume in one second of the predicted value (FEV1%) , dyspnea index of modified British Medical Research Council (MMRC), and exercise performance index of 6-min walking test (6MWT) in the two groups were observed. Results (1) After treatment, FEV1%, MMRC dyspnea index, 6MWT scores and BODE index overall scores of severe and extremely severe patients in the treatment group were much improved(P < 0.05 compared with those before treatment ), but BMI was not much improved(P > 0.05). MMRC dyspnea index, 6MWT scores and BODE index overall scores of severe and extremely severe patients inthe control group were much improved (P<0.05 compared with those before treatment) , b ut the improvement of FEV1% and BMI was not obvious(P > 0.05).(2) Except for BMI, the parameters of FEV1%, MMRC dyspnea index, 6MWT scores and BODE index overall scores of the treatment group were much improved as compared with those of the control group after treatment(P < 0.05). Conclusion Fufei Gushen Decoction combined with inhalation of Seretide exerts certain effects on decreasing the BODE index scores, relieving symptoms, and improving pulmonary function, exercise performance and the quality of life of COPD patients with lung-kidney deficiency interweaved with phlegm and blood stasis at stable stage.

BACKGROUNDTo investigate the relationship between cytokine level and cancer cachexia on murine model, and to observe the effects of regular dose of indomethacin on cancer cachexia and survival of mice.

METHODSC57 mice bearing Lewis lung carcinoma were used to establish murine cancer cachexia model. The serum cytokine levels (IL-1, IL-6, TNF-α and IFN-γ) and body weight of the mice were measured at different time points before and after treatment with daily intraperioneal injection of either indomethacin (1 mg/kg) or saline.

RESULTSThe mice in cancer cachexia group had significantly higher serum levels of IL-1, IL-6 and TNF-α ( P < 0.05) and lower body weight ( P < 0.05) than those in healthy control group. Compared to saline treatment, indomethacin intervention apparently down regulated the levels of IL-1, IL-6 and TNF-α ( P < 0.05 ), and remarkably prolonged the survival of mice ( P < 0.05). No significant difference in IFN-γ level was observed between cancer cachexia and healthy control groups ( P > 0.05), as well as between indomethacin and saline groups ( P > 0.05).

CONCLUSIONSThe results suggest that serum IL-1, IL-6 and TNF-α are possibly associated with cancer cachexia, however, IFN-γ seems to be irrelevant. Indomethacin may potentially ameliorate cancer cachexia through down-regulating levels of cytokines.

Objective To investigate the effects of Dingkoulizhong decoction on cellular immune factors and adverse reactions in patients with advanced gastric cancer treated with chemotherapy.Methods One hundred and thirty-eight patients with advanced gastric cancer were enrolled in our hospital from October 2014to December 2016,and were randomly divided into control group (n =69) and observation group (n =69) by using the random number table.The patients of the control group were treated with FOLFOX4 chemotherapy (oxaliplatin + calcium folinate + fluorouracil),while the patients of the observation group were given by the treatment of Dingkoulizhong decoction on the basis of the control group.The peripheral blood samples of the patients were collected before and after the treatment.The levels of cellular immune factors CD3 +,CD4 +,CD8 + and CD4 +/CD8 + were detected,and the clinical efficacy and adverse reactions of the patients of the two groups were observed.Results After the treatment,the number of complete remission (CR),partial remission (PR),stable disease (SD) and progressive disease (PD) in the observation group were 16,25,16 and 12 cases respectively,while the control group were 9,20,19 and 21 cases respectively,and there was a statistically significant difference in the distribution of clinical efficacy between the two groups (Z =4.381,P =0.036).Compared with the control group,the clinical benefit rate (CBR) of the observation group was significantly improved (59.42％ vs.42.03％),with a statistically significant difference (x2 =4.175,P =0.041).The cellular immune factors CD3 + [(52.67 ±6.21)％ vs.(53.45 ±6.54)％],CD4 + [(23.56 ±3.85)％ vs.(24.09±2.91)％],CD8 +[(28.16±3.49)％ vs.(27.87±3.26)％] and CD4 +/CD8+(1.13 ± 0.27 vs.1.19 ±± 0.31) of the patients of the observation group showed no statistically significant difference (t=0.718,P=0.474;t=0.912,P=0.363;t=0.504,P=0.615;t=1.212,P=0.227) beforeand after the treatment,but the cellular immune factor CD3 + [(50.36 ± 3.74)％ vs.(53.13 ± 6.12)％],CD4 +[(21.26±2.37)％ vs.(23.44 ±3.96)％] andCD4+/CD8*(0.96±0.26vs.1.15±0.25) of the patients of the control group after the treatment were significantly lower than those before the treatment,and CD8 +[(31.64 ± 4.05) ％ vs.(27.98 ± 3.52) ％] after the treatment was significantly higher than that before the treatment,all with statistically significant differences (t =3.208,P ＜ 0.001;t =3.924,P ＜ 0.001;t =4.289P ＜ 0.001,t =5.666,P ＜ 0.001).Compared with the control group,the level of CD3 + [(53.45 ± 6.54) ％ vs.(50.36±±3.74)％],CD4+[(24.09±±2.91)％ vs.(21.26±2.37)％] andCD4+/CD8+(1.19±0.31vs.0.96 ± 0.26) of the patients of the observation group after the treatment were significantly improved,and CD8 +[(27.87 ± 3.26) ％ vs.(31.64 ± 4.05) ％] was significantly decreased,all with statistically significant differences (t=3.407,P=0.001;t =6.264,P＜0.001;t =4.722,P＜0.001;t =6.023,P＜0.001).Compared with the control group,the total adverse reaction rate of the observation group was significantly decreased (36.23％ vs.55.07％),with a statistically significant difference (x2 =4.936,P =0.026).Conclusion Dingkoulizhong decoction can significantly improve the clinical efficacy in patients with advanced gastric cancer treated with chemotherapy,alleviate the immune function damage caused by chemotherapy,and it can reduce the occurrence of adverse reactions.

Objective: To observe the effects of axial vascular network flap of scalp or anterolateral thigh perforator flap with fascia lata on repairing defects after radical resection of scalp carcinoma in patients. Methods: From February 2006 to December 2015, twenty-one patients with scalp carcinoma were admitted to our hospital, and the carcinoma invaded external lamina or full-thickness of skull and dura mater. After perfect preoperative examination, carcinoma and scalp tissue in 3 to 5 cm from the edge of carcinoma, external lamina or full-thickness of skull and invaded dura mater were resected and sentinel lymph nodes around carcinoma were cleaned in 3 to 4 days after admission. The postoperative defects with size reached from 11 cm×8 cm to 22 cm×18 cm. The flap transplantation was performed at the same time when quick frozen pathological examination results of resected scalp carcinoma margin tissue, skull, dura mater margin and basal tissue, and sentinel lymph nodes showed completely negative. Defects in 3 elderly patients were repaired by single or multiple axial scalp vascular network flaps, with the resected flaps size ranged from 12 cm×7 cm to 19 cm×14 cm. Defects in the other 18 patients were repaired by anterolateral thigh perforator flaps with fascia lata, with the resected flaps size ranged from 13 cm×10 cm to 23 cm×19 cm and the resected fascia lata size ranged from 8 cm×7 cm to 10 cm×10 cm. The head donor site of flap was repaired by medium thickness skin of head and back; the thigh donor site of flap was repaired by medium thickness skin of thigh on the same side. All patients gave up postoperative radiotherapy, chemotherapy, and other follow-up treatments. Results: After operation, the flap and skin in all patients survived completely, with no vascular crisis or other condition. During the follow-up for 6 months to 9 years, all patients showed good appearance except for baldness in operation area of head, with no obvious malformation in head donor site of flap and skin, no swollen external hernia in the brain tissue, and no local recurrence or distant metastasis of carcinoma. The appearance of thigh donor site of flap and skin was good, with normal muscle strength and movement of lower limbs. Conclusions Patients with scalp carcinoma were performed with radical resection of carcinoma, and axial vascular network flap of scalp or anterolateral thigh perforator flap with fascia lata were applied to repair the postoperative defects, with good appearance of head operation area and no local recurrence or distant metastasis of carcinoma.

Objective:To investigate the correlation between the expressions of miR-524-5p and sex determining region Y box protein 9 (SOX9) in advanced gastric cancer and their influences on the efficacy and prognosis of chemotherapy.Methods:A total of 82 patients diagnosed as advanced gastric cancer who received DCF (docetaxel + cisplatin + fluorouracil) chemotherapy in 910th Hospital of Joint Logistics Support Force of Chinese People′s Liberation Army from January 2015 to December 2017 were selected as the research objects. The expression levels of miR-524-5p and SOX9 in gastric cancer tissues were detected by fluorescence quantitative PCR. The correlation between the expressions of miR-524-5p and SOX9 was analyzed, the total effective rates of chemotherapy in patients with different miR-524-5p and SOX9 expression levels were compared, and the predictive value of miR-524-5p combined with SOX9 on the efficacy of chemotherapy was analyzed. Overall survival (OS) and progression-free survival (PFS) were analyzed.Results:The expressions of miR-524-5p and SOX9 were not related to gender or age of patients with advanced gastric cancer (all P>0.05), but were related to the degree of differentiation ( χ2=3.577, P=0.001; χ2=5.654, P<0.001) and distant metastasis ( χ2=2.466, P=0.016; χ2=5.218, P<0.001) of patients with advanced gastric cancer. There was a negative correlation between the expressions of miR-524-5p and SOX9 in advanced gastric cancer ( r=-0.348, P=0.001). According to the median expressions of miR-524-5p and SOX9 in gastric cancer tissues, patients were divided into high expression and low expression groups, miR-524-5p≥0.64 was high expression ( n=41), <0.64 was low expression ( n=41), SOX9≥1.84 was high expression ( n=41), and <1.84 was low expression ( n=41). The total effective rate of advanced gastric cancer patients with high expression of miR-524-5p was 58.54% (24/41), which was higher than that of patients with low expression of miR-524-5p (24.39%, 10/41), and there was a statistically significant difference ( χ2=9.484, P=0.002). The total effective rate of advanced gastric cancer patients with high expression of SOX9 was 21.95% (9/41), which was lower than 60.97% (25/41) of patients with low expression of SOX9, and there was a statistically significant difference ( χ2=12.863, P<0.001). Receiver operating characteristic curve analysis showed that the expressions of miR-524-5p and SOX9 had predictive value for the efficacy of chemotherapy, and the area under the curve was 0.753 (95% CI: 0.644-0.861, P<0.001) and 0.660 (95% CI: 0.540-0.780, P=0.014) respectively. The combination of miR-524-5p and SOX9 had predictive value for the efficacy of chemotherapy, and the area under the curve was 0.768 (95% CI: 0.667-0.868, P<0.001). The median PFS and OS of patients with high expression of miR-524-5p were 8 months and 14 months, which were longer than those of patients with low expression of miR-524-5p (6 months, 9 months), and there were statistically significant differences ( χ2=21.160, P<0.001; χ2=29.730, P<0.001). The median PFS and OS of patients with high expression of SOX9 were 7 months and 10 months, which were shorter than those of patients with low expression of SOX9 (8 months, 12 months), and there were statistically significant differences ( χ2=6.345, P=0.012; χ2=4.107, P=0.043). Conclusion:There is a negative correlation between the expressions of miR-524-5p and SOX9 in advanced gastric cancer tissues. The chemotherapy efficacy and prognosis of patients with high expression of miR-524-5p and low expression of SOX9 are better than those of patients with low expression of miR-524-5p and high expression of SOX9.

Objective To study the characteristics of hyperphenylalaninemia (HPA) and the differences in blood and urine metabolic index and their correlation.Methods A total of 137 patients with HPA diagnosed by the Pediatric Inherit Metabolism and Endocrine Department,Guangdong Women and Children's Hospital,Guangzhou Medical University from January 2014 to June 2017,were enrolled.Tandem mass spectrometry (MS/MS),gas chromatography/ mass spectrometry (GC-MS) and high performance liquid chromatography (HPLC) were used to analyze the concentration of blood and urine metabolites in children,and the patients were divided into different groups according to the drug load test of tetrahydrobiopterin (BH4) and dihydrobiopterindine reductase (DHPR) deficiency.The HPA metabolite analysis of horizontal concentration by statistical differences and correlation analysis were performed.Results Among the 137 cases of HPA,there were 101 cases (73.7％) of phenylalanine hydroxylase deficiency (PAH),and among them 21 cases (15.3％) were classic phenylketonuria (PKU),37 cases were mild PKU (27.0％),43 cases (31.4％) wcrc mild HPA.Thcrc were 22 cases (16.1％) with BH4 reaction,and 79 cases (57.7％) of non-reactive type.Besides,there were 36 cases (26.3％) of tetrahydrobiopterin deficiency (BH4 D),of which 6-pyruvoyl tetrahydropterin synthase deficiency (PTPS) in 34 cases (24.8％) and dihydrobiopterindine reductase deficiency (DHPR) in 2 cases (1.5％).Urinary phenylacetic acid (r =0.673,P ＜ 0.01),phenyllactic acid (r =0.736,P ＜ 0.01),phenylpyruvic acid (r =0.642,P ＜ 0.01) were significantly correlated with blood phenylalanine (Phe) concentration,and the neopterin (N) (r =0.442,P ＜ 0.01) and biopterin (B) (r =0.398,P ＜ 0.01) had low correlation.Urinary phenylacetic acid,phenyllactic acid and phenylpyruvic acid had no correlation with urinary pterin.There were significant differences among PTPS deficiency group,BH4 response type,and non-reactive type(all P ＜ 0.05),but no significant difference between the BH4 reaction type and the non-reactive group (P ＞ 0.05).Conclusions Through the analysis of the different types of HPA metabolic profiles,it can help to master the incidence and characteristics in the region,within a certain concentration range of blood Phe,the phenylacetic acid,phenyllactic acid,phenylpyruvic acid should not be tested by GC-MS alone.Uterine erythropoietin analysis of BH4D classification and identification of BH4 reaction,non-reactive PKU have a supporting role,so master the metabolic index of various types of concentration and relevance of HPA,it can provide basis for early diagnosis,accurate treatment and follow-up.
