Abstract: Objective To analyze the changes of coagulation indicators in patients with hepatitis B complicated with Clonorchis sinensis (C. Sinensis), and provide reference value for diagnosis, drug using and prognosis monitoring. Methods　The patient samples were collected from the Third Affiliated Hospital of Sun Yat-sen University from June 2018 to February 2022 and divided into six groups. They were 40 healthy patients, 47 patients with simple chronic hepatitis B, 47 patients with post-hepatitis B liver cirrhosis, 40 patients with C. Sinensis mono-infection, 30 patients with chronic hepatitis B patients co-infected with C. Sinensis and 27 patients with post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis. Four coagulation indexes, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB), were detected and compared among the groups. Results Compared with the healthy group, C. Sinensis mono-infection group had higher level of FIB and delayed PT, APTT; chronic hepatitis B group and chronic hepatitis B patients co-infected with C. Sinensis group had delayed PT, APTT, TT and significant lower FIB, these differences were statistically significant (all P<0.05). Compared with simple chronic hepatitis B group, post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Compared with the post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis, post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis group had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Conclusions The coinfection of C. Sinensis will further aggravate the coagulation dysfunction of HBV patients, leading to poor treatment and prognosis. HBV patients will have worse coagulation function in the process to post-hepatitis B liver cirrhosis; Therefore, it is important to pay attention to C. Sinensis co-infection when treating HBV patients, so that further guidance on clinical use and monitoring of prognosis can be provided.

Objective:To observe the clinical efficacy of treating infantile diarrhea due to spleen deficiency with five-step pediatric tuina of Huxiang school. Methods:Using a randomized controlled trial design, sixty eligible kids with diarrhea due to spleen deficiency were randomized into an observation group and a control group, with 30 cases in each group. The observation group was intervened by the five-step pediatric tuina method of Huxiang school, and the control group received conventional tuina treatment. The intervention was conducted once a day, consecutive 5-day treatment as 1 course, at a 2-day interval between courses, successively for a total of 4 courses. Changes in the primary and secondary symptoms of diarrhea due to spleen deficiency were observed, and the clinical efficacy was evaluated. Results: After treatment, the scores of primary and secondary symptoms and the general score of diarrhea due to spleen deficiency were improved; the improvements in fecal form and frequency, decreased appetite, bloating after meals and fatigue and sluggishness were more significant in the observation group than in the control group. Conclusion: The five-step pediatric tuina method of Huxiang school and conventional tuina both can improve the primary and secondary symptoms in infantile diarrhea due to spleen deficiency, while the former one can produce more significant efficacy.

An HPLC method for the determination of geniposide concentration in mouse plasma was developed and the pharmacokinetics after intranasal administration of Xingnaojing microemulsion (XNJ-M) and mPEG2000-PLA modified Xingnaojing microemulsion (XNJ-MM) were investigated. Eighty mice were treated by XNJ-M and XNJ-MM nasally. The plasma samples were collected at different times and the drug in samples was detected by HPLC. The pharmacokinetic parameters were calculated by the software of Kinetica. The pharmacokinetic parameters of geniposide of XNJ-M were C(max) (4.36 +/- 2.69) mg x L(-1), t(max) 1 min, MRT (29.73 +/- 4.54) min, AUC (53.63 +/- 14.03) mg x L(-1) x min. The pharmacokinetic parameters of geniposide of XNJ-MM were C(max) (9.75 +/- 4.14) mg x L(-1), t(max) 1 min, MRT(22.34 +/- 2.90) min, AUC (131.87 +/- 40.13) mg x L(-1) x min. Geniposide can be absorbed into blood in a higher degree after intranasal administration with XNJ-MM compared to XNJ-M, which maybe caused by its less irritating and more absorption.

OBJECTIVETo provide a new material for producing the Rhodiolasachalinensis products, the effect of methyl jasmonate (MeJA) on callus biomass and effective compound accumulation of Rhodiolasachalinensis was studied.

METHODThe calluses-cultured in 3 L-air lift balloon type bioreactor were treated with MeJA after 20 d of bioreactor culture and the effect of MeJA concentration and treatment days on callus biomass, salidroside or polysaccharide accumulation and superoxide dismutase (SOD) and peroxidase (POD) activities were investigated.

RESULTThe callus biomass was not significantly different after MeJA treatment (125) for 0-6 d but obviously decreased after 6 d treatment. The maximum salidroside or polysaccharide contents and SOD or POD activities were found after 4 d treatment of MeJA. MeJA concentration significantly affected callus biomass and effective compound accumulation, biomass decreased at MeJA concentrations higher than 125 μmol x L(-1). However, the effective compound contents were determined at higher MeJA concentration, and the highest salidroside and polysaccharide accumulation was found at 225 and 275 μmol x L(-1) MeJA, respectively and the maximum SOD and POD activities was found at 225 μmol x L(-1) MeJA. The effective compound contents in callus were compared with field-grown plants. Salidroside contents in calluses were 1.1-fold and 2. 4-fold more than in plant roots and stem or leave, respectively. Polysaccharide content in calluses were 3. 6-fold and 8.0-fold more than in plant roots and stem or leave, respectively.

CONCLUSIONSalidorside and polysaccharide in Rhodiolasachalinensiscalluses improved by MeJA treatment, 225 μmol x L(-1) MeJA and 4 d treatment were optimal. The effective compound contents in callus were obviously higher than in field-grown plants. Therefore, bioreactor culture is efficient for obtaining mass effective compounds of Rhodiolasachalinensis by culturing calluses. This method could provide an alternative material source for production of Rhodiolasachalinensis products.
