Objective To investigate the expression of miRNA associated with hepatic fibrosis induced by Schistosoma ja-ponicum soluble egg antigen stimulation in mouse hepatocytes(AML12),so as to lay the foundation for clarifying the mecha-nism of schistosome infection leading to hepatic fibrosis. Methods The expressions of miR-122,miR-182,miR-23b,miR-27b and KSRP in AML12 cells treated with SEA were measured by q-PCR. KSRP protein in cell lyses was measured by Western blotting. AML12 cells were transfected with miR-27b precursor or anti-miR-27b for 24 h,then q-PCR was adopted to determine KSRP mRNA,and KSRP protein was detected by Western blotting. Results The expressions of miR-182,miR-23b and miR-27b were decreased and miR-122 was increased in AML12 cells following SEA treatment(all P<0.05). An increase of mRNA and protein of KSRP expression was also observed in AML12 cells after SEA stimulation(both P<0.05). In addition,KSRP mRNA expression was not changed significantly in AML12 cells transfected with anti-miR-27b or miR-27b precursor,and miR-27b precursor reduced KSRP protein expression as compared with the control. In contrast,the expression of KSRP protein was increased in the anti-miR-27b group and decreased in the miR-27b precursor group. Conclusions After the stimulation of SEA,the expressions of a variety of liver fibrosis-related miRNAs and KSRP change in murine hepatocytes,including miR-27b. And miR-27b can regulate the expression of KSRP. These findings might lay a foundation for further study on the molecular mechanism of fibrosis induced by schistosome infection.

Objective To investigate the clinical efficacy of prucalopride in the treatment of severe chronic constipation.Methods The clinical data of 60 patients with severe chronic constipation [slow transit constipation (STC), functional defecation disorder (FDD) and constipation-predominant irritable bowel syndrome (IBS-C)] who were admitted to the Third Affiliated Hospital of Nanjing University of Chinese Medicine from February to August 2014 were prospectively analyzed.A prospective, clinical observational study was performed.Treatment plans included that patients withdrew the initial treatments of laxative and exema and took orally 2 mg prucalopride once daily for 2 weeks, and continued to be treated by oral prucalopride if frequency of the spontaneous complete bowel movement (SCBM) per week was satisfactory (or improvement of symptoms was more than 50％) till 4 weeks, and then were followed up after stopping prucalopride.If improvement of symptoms was less than 50％ after 2-week treatment, other treatment plans were performed according to symptoms of patients from week 3 to week 6 : (1) for patients with STC, prucalopride + two chain bacillus subtilis probiotic capsules were administered orally if patients were satisfied with frequency of SCBM per week and without improvement of abdominal distension;prucalopride + Chinese herb decoction were administered orally if patients had improvement of frequency of SCBM per week with abdominal distension or poor stool output;oral prucalopride + acupuncture were administered if patients were unsatisfied with frequency of SCBM per week or less bowel movements and without improvement of abdominal distension or poor stool output.(2) For patients with FDD, oral prucalopride + acupuncture + biofeed-back therapy were administered.(3) For patients with IBS-C, prucalopride + two chain bacillus subtilis probiotic capsules were administered orally if patients had abdominal distension;prucalopride Chinese herb decoction were administered orally if patients had improvement of frequency of SCBM per week and no improvement of abdominal distension or poor stool output.All patients used a diary for recording the frequency of SCBM per week, stool consistence, exertion in defecation and adverse reactions, which was submitted to doctors for inputting data at the return visit weekly.Results There was good overall medicine compliance in patients.Of 60 patients, 43 patients completed treatments (21 with STC, 11 with FDD and 11 with IBS-C).After 2-week treatment, there were 19 patients with satisfied therapeutic effects, 14 with improvement of constipation and 10 with poor therapeutic effects.After 4-week treatment, constipation in 17 patients was cured, constipation in 18 patients was improved,and constipation in 8 patients was not improved.Nineteen of 60 patients were complicated with adverse reactions within 1 week of the medication, including 6 patients dropping out of the trial due to medication withdrawal and others with improvement by symptomatic treatment or spontaneous remission.Conclusions Prucalopride is effective for the treatment of severe chronic constipation with a good toleration, and it can improve the overall satisfaction of patients combined with Chinese herb decoction and acupuncture.

Objective To explore the effect of pre-filled catheter flushing device on the sealing of venous indwelling needle. Methods One hundred and sixteen patients with venous indwelling needle were assigned into observation group, in which pre-filled catheter flushing device was used to seal the needle tube and another 109 with venous indwelling needle as control group, in which the needle tube was sealed with 50U/mL heparin saline.The two groups were compared in terms of blockage of the tube, phlebitis, catheter-associated infection, indwelling time of the needle and time for nurses to seal it.Results The rates of blockage of catheter, phlebitis and catheter-associated infection of the observation group were all lower than those of the control group.The indwelling time of the needle was significantly longer than that in the control group.The time for nurses to seal the catheter was significantly shorter than that in the control group(all P<0.05). Conclusion Pre-filled catheter flushing device can reduce complication rate and improve working efficiency of nurses.

Objective:To study the differences of clinical features between aggressive posterior retinopathy of prematurity (APROP) and general retinopathy of prematurity (GROP) and to find the risk factors of APROP.Method:From January 2014 to December 2018, newborns with retinopathy of prematurity (ROP) hospitalized in our hospital were retrospectively studied. According to the diagnosis criteria of APROP, the newborns were assigned into GROP group and APROP group. Their clinical data, treatment and perinatal data were collected. SPSS 18.0 was used to compare the differences between the two groups.Result:A total of 127 newborns were included in the study, 107 in the GROP group and 20 in the APROP group. 91.6% (98/107) infants with gestational age (GA) <32 w were in the GROP group and 95.0% (19/20) in the APROP group. 84.1% (90/107) infants with birth weight (BW) <1 500 g were in the GROP group and 90.0% (18/20) in the APROP group. No significant differences existed of GA and BW between the two groups. 53.3% (57/107) infants in the GROP group received ≥2 times of blood transfusion, significantly lower than 85.0% (17/20) in the APROP group ( P<0.05). Mechanical ventilation (MV) was used in 81.3% (87/107) infants in the GROP group with most duration less than 7 days (69.2%, 74/107). MV was used in all infants in the APROP group with most duration longer than 7 days (65.0%, 13/20). The APROP group had significantly longer MV duration than the GROP group ( P<0.05). Some of the GROP group received laser photocoagulation therapy and all had good prognosis. Most of the APROP group received intravitreal injection and some of them combined with laser photocoagulation. The majority of them had favorable prognosis. Conclusion:The APROP group and the GROP group have similar general clinical characteristics. Increased blood transfusion and elongated MV duration may be risk factors for APROP.

BACKGROUND:Hepatic fibrosis in chronic liver disease can be reversed. Studies have shown that Periplaneta americana extract has anti-fibrosis effect, and has protective effect on the experimental hepatic fibrosis rats.
OBJECTIVE:To observe the effect of Periplaneta americana extract sticky sugar amino acid on hepatic fibrosis, and to primarily explore the mechanism of sticky sugar amino acid against hepatic fibrosis.
METHODS:Rat models of immune hepatic fibrosis were induced by pig serum and intragastricaly administered 0.5, 0.25, 0.10 g/kg sticky sugar amino acid. Four indexes of hepatic fibrosis were detected by radioimmunoassay. Immunohistochemical staining wasused to measure transforming growth factor beta 1, tissue inhibitor of metaloproteinase protein expression intensity and positive cel rate, to determine the correlation of different concentrations of sticky sugar amino acid, transformation growth factorbeta 1 and tissue inhibitor of metaloproteinase.
RESULTS AND CONCLUSION:(1) The Periplaneta americana extract sticky sugar amino acid reduced the levels of laminin, type III procolagen, type IV colagen and hyaluronidase (P< 0.01) and reduced the expression of transformation growth factor beta 1 and tissue inhibitor of metaloproteinase 1 in liver tissue (P< 0.01). (2) Sticky sugar amino acid concentration and transformation growth factor beta 1 and tissue inhibitor of metaloproteinase 1 protein expression showed a significant negative correlation (|r| > 0.9). (3) Results confirmed that the Periplaneta americana extract sticky sugar amino acid can change the reversal of hepatic fibrosis. Its mechanism of action is associated with expression of transforming growth factor beta 1 and tissue inhibitor of metaloproteinase 1 inhibited by sticky sugar amino acids.

Objective To evaluate the safety and efficacy of Yinhua Pinggan granule of Qingjie Xuantou lung defense prescription in the treatment of patients with upper respiratory tract infection accompanied by traditional Chinese medicine (TCM) syndrome of pathogen stagnated in lung-defense phase and to explore the best effective dose.Methods A randomized double blinded, positive drug parallel controlled and multicentric clinical trial was conducted, 270 patients with upper respiratory infection were collected from the First Affiliated Hospital of Zhejiang Chinese Medical University, Affiliated Hospital of Jiangxi Medical University, the Second Affiliated Hospital of Tianjin University of TCM, Tongde Hospital of Zhejiang Province, and Fujian Province Institute of TCM, after screening only 242 cases were consistent with the criteria of enrollment into the Per-Protocol Set (PPS) population, and they were divided into three groups: high dose observation group (82 cases), low dose observation group (79 cases) and control group (81 cases). The high and low dose observation groups were treated with Yinhua Pinggan granule (5 g per bag), high dose means once 1 bag orally taken 3 times a day, low dose indicates once 1 bag taken twice a day; the control group was treated with Yinqiao Jiedu granule (5 g per bag) once 1 bag, 3 times a day; the curative effects of the above groups were all evaluated after consecutive oral administration of the drug respectively for 1 therapeutic course (3 days). The main efficacy evaluation indexes included the TCM syndrome total score and the total score of main symptoms of upper respiratory tract infection; the secondary efficacy evaluation indexes included the situations of patients with different scores of main symptoms of fever and chills, and of disappearance of TCM symptoms; the clinical comprehensive therapeutic effect and the changes of proportion of neutrophils were observed and the safety of drugs was evaluated.Results In PPS population, after treatment the TCM syndrome total score and the total score of main symptoms in the control group and the high and low dose observation groups were all significantly lower than those before treatment, on the 3rd day statistical significant differences were shown (4.4±3.9 vs. 15.5±4.6, 3.7±3.2 vs. 15.0±4.3, 3.0±2.7 vs. 15.2±3.9, 2.8±2.6 vs. 9.7±2.7, 2.3±2.1 vs. 9.5±2.5, 2.0±1.9 vs. 9.6±2.4, respectively, all P < 0.01). After treatment for 1 day, the numbers of patients with 6 score in the control group and the high and low dose observation groups were reduced significantly compared with those before treatment in main symptoms of fever with chills (7 vs. 32 cases, 6 vs. 31 cases, 4 vs. 28 cases, respectively); 3 days after treatment, compared with those before treatment, the numbers of patients with main symptoms of fever with chills score being 0 were significantly increased in the above three groups (65, 73, 77 cases vs. 0 cases, respectively), the numbers of patients with the score being 3 were significantly decreased (16 vs. 47 cases, 5 vs. 46 cases, 5 vs. 52 cases, respectively); the control and high dose observation group had no patients with the score being 6, there was only 1 case with the score being 6 in the low dose observation group. The results showed that the treatments of high and low dose observation groups and the control group all could alleviate the clinical symptoms, and the changes of numbers of patients with the scoresbeing 0 and 3 in high and low dose groups were more significant than those in the control group (respectively 73, 77 vs. 65 cases, 5, 5 vs. 16 cases, allP < 0.05), showing that the antipyretic effect of Yinhua Pinggan granule was superior to that of the Yinqiao Jiedu granule. The disappearance rates of fever with chills symptoms in high and low dose observation groups were significantly higher than that in the control group [respectively 93.9% (77/82), 92.4% (73/79) vs. 80.2% (65/81), allP < 0.05]. The TCM syndrome cure and obvious effect rate and effective rate in high and low dose observation groups were higher than those in the control group [respectively 87.80% (72/82), 79.75% (63/79) vs. 74.07% (60/81) and 98.78% (81/82), 96.20% (76/79) vs. 96.30% (78/81)]; the cure and marked effective rate and effective rate of controlling symptoms of upper respiratory tract infection in high and low dose observation groups were higher than those in the control group [respectively 78.05% (64/82), 74.68% (59/79) vs. 65.43% (78/81) and 98.78% (81/82), 96.20% (76/79) vs. 96.30% (78/81)], comparisons of efficacy among the three groups possessed clinical practical significance, but the differences were not statistically significant (allP > 0.05). The percentages of neutrophils in high and low dose observation groups and control group were significantly lower than those before treatment (respectively 0.61±0.08 vs. 0.63±0.08, 0.62±0.08 vs. 0.64±0.08, 0.61±0.09 vs. 0.64±0.09, allP < 0.05). Yinhua Pinggan granule was safe in the prescribed course of treatment and range of therapeutic dose.Conclusions Yinhua Pinggan granule is a safe and effective drug in the treatment of patients with upper respiratory tract infection accompanied by syndrome of pathogen stagnated in lung-defense phase.
