Conclusion:The established method has good specificity, repeatability and durability, and it can effectively distinguish the common counterfeits of Pulsatilla chinensis, and provide the basis of quality control and selection of origin for Pulsatilla chinensis.

This study aimed to investigate the effect and mechanisms of Ephedra Herb (EH) extract on adriamycin-induced nephrotic syndrome (NS), providing an experimental basis for the clinical treatment of NS. Hematoxylin and eosin staining, creatinine, urea nitrogen, and kidn injury molecule-1 were used to evaluate the activities of EH extract on renal function. The levels of inflammatory factors and oxidative stress were detected by kits. The levels of reactive oxygen species, immune cells, and apoptosis were measured by flow cytometry. A network pharmacological approach was used to predict the potential targets and mechanisms of EH extract in the treatment of NS. The protein levels of apoptosis-related proteins and CAMKK2, p-CAMKK2, AMPK, p-AMPK, mTOR and p-mTOR in the kidneys were detected by Western blot. The effective material basis of EH extract was screened by MTT assay. The AMPK pathway inhibitor (compound C, CC) was added to investigate the effect of the potent material basis on adriamycin-induced cell injury. EH extract significantly improved renal injury and relieve inflammation, oxidative stress, and apoptosis in rats. Network pharmacology and Western blot results showed that the effect of EH extract on NS may be associated with the CAMKK2/AMPK/mTOR signaling pathway. Moreover, methylephedrine significantly ameliorated adriamycin-induced NRK-52e cell injury. Methylephedrine also significantly improved the phosphorylation of AMPK and mTOR, which were blocked by CC. In sum, EH extract may ameliorate renal injury via the CAMKK2/AMPK/mTOR signaling pathway. Moreover, methylephedrine may be one of the material bases of EH extract.

Objective To understand the current prevalence of clonorchiasis in Jiangxi Province. Methods A survey was performed according to the scheme of the 3rd Principal Human Parasites of Jiangxi Province. Based on the ecological regions,a stratified cluster sampling method was applied by the economic and geographic situation. In rural areas,the investigation of C. si?nensis was carried out together with the soil?transmitted helminths investigation,and in the urban areas,the random cluster sam?pling method was applied for the C. sinensis investigation. There were 92 survey sites from 32 counties. The eggs of C. sinensis in stool were examined by Kato?Katz technique,and health knowledge was also investigated by questionnaires in some people at the same time. Results A total of 23 606 sample residents were investigated,and 138 were found infected with C. sinensis, with the infection rate of 0.58%. Light infection was found in most of them. Totally 124 C. sinensis infected persons focused in Xinfeng County,and only a few of infected people scattered in the other counties. In Xinfeng County,851 residents were investi?gated. Among them,the infected people were found in all the age groups except the 0?year age group. The highest infection rate appeared in the 70? years group(24.00%). The male infection rate was 20.29%,which was higher than that of the female (6.25%),showing a statistically significant difference(P<0.01). The infection rate was highest in the population who received high school or technical secondary school education(31.48%). For the occupation distribution,the infection rate was highest in public officers(39.39%). The questionnaire survey showed that the infection rate in the populations in Xinfeng County who had the history of eating raw fish or raw shrimp was 33.15%. Conclusions The distribution of C. sinensis infection presents a region?al aggregation in Xinfeng County,but in other areas,the distribution is sporadic. It is necessary to continue to carry out the para?sitic disease screening,and in Xinfeng County,it is necessary to strengthen the comprehensive prevention and control interven?tion.

Methods The teams that took part in the competition were formed from 20 Class A tertiary hospitals,with 2 contestants per team. The competition contents included written examination and skill opera?tion. The written examination involved the life cycle of parasites,immunological basis,detecting techniques,etiological diagno?sis etc.,and the skill operation involved making and dying thin and thick blood smears,making Kato?Katz’s fecal thick smears, as well as microscopic examinations of smears. Results A total of 40 participants took part in the competition. Their total aver?age score was 97.3±22.4 with the pass rate of 15.0%,in which the mean score of theoretical knowledge was 56.6±12.8 with the pass rate of 52.5%,and the mean score of skill operation was 40.8±12.4 with the pass rate of 5.0%. In the written examination, the scoring rate of the life cycle of soil?transmitted helminths was the highest(90.0%),and the rate of the basic knowledge of food?borne parasites was the lowest(31.5%). Both the pass rates of blood smear making and examination were higher than those of Kato?Katz’s thick smears,and the differences were statistically significant( both P<0.05). The detection rates of Plasmodi?um vivax,Plasmodium falciparum,Plasmodium ovale and negative slides of the contestants were 38.8%,45.0%,35.0%and 25.0% respectively. As to the microscopic examination of helminth eggs,the detection rate of Trichuris trichiura egg was the highest(87.5%),and the rate of the Sparganum mansoni egg was the lowest(2.5%). The scores of Kato?Katz’s thick smear making and examination of the contestants from the provincial level hospitals were higher than those from the city level hospitals (both P<0.05),and the score of those from teaching hospitals in Kato?Katz’s thick smear making was higher than that of those from non?teaching hospitals(P < 0.05). Conclusions The technique level of professionals from the clinic laboratory of the Class A tertiary hospitals cannot meet the needs of the diagnosis of parasitic diseases in Jiangxi Province ,which should arouse the attention of the health authorities and hospitals.

This study was aimed to investigate the diuretic effect ofMori Cortex and to identify effective fractions inM. Cortex. Metabolic cages were used to firstly observe the diuretic effect ofM. Cortex aqueous extracts on rats. Medications were continuously given for 5 days to screen for the best dosage of diuretic effect. Picric acid assays were used to detect creatinine levels in serum and urine after 5-day medication. Then, the diuretic effect of each chemical split fraction inM. Cortex was studied in order to indentify the effective parts. The results showed that after administration ofM. Cortex aqueous extracts for 3 to 5 days, compared with the control group, there was a significant diuretic effect on rats (P<0.05 orP<0.01). And the medium-dose ofM. Cortex aqueous extracts showed the best effect (P<0.01). However,M. Cortex aqueous extracts had no significant effect on creatinine levels in serum and urine. Assays of diuretic effect of chemical split fractions ofM.Cortex indicated that compared with the control group, 30% ethanol fraction and fatty oil fraction had the best diuretic effect (P<0.01). It was concluded thatM.Cortex aqueous extracts had a significant diuretic effect. And the chemical fractions contributed mostly to this effect were mainly existed in the 30% ethanol fraction and fatty oil fraction.
