The renal toxicity of rats after a single dose ofMeng-Gen-Wu-Su (mercury) processed products,Meng-Gen-Wu-Su (mercury)-18-composition pill, mercuric sulfide, mercuric chloride, and mercurous chloride was studied. Fifty-four male Wistar rats were randomly divided into nine groups according to body weights (6 rats in each group): normal control group, low and high dose groups (0.033, 0.33 g·kg-1·d-1) ofMeng-Gen-Wu-Su (mercury) processed products, low and high dose groups (0.29, 2.9 g·kg-1·d-1) ofMeng-Gen-Wu-Su (mercury)-18-composition pill, simplified prescription ofMeng-Gen-Wu-Su (mercury)-18-composition pill group (0.26 g·kg-1·d-1), mercuric sulfide group (17.39 mg·kg-1·d-1), mercuric chloride group (4.06 mg·kg-1·d-1) and mercurous chloride group (35.3 mg·kg-1·d-1). After acclimation for one week, once oral administration was given to each group of rats. After 24 h, function and morphological changes of liver and kidney were detected. Mercury accumulation in kidney was determined by inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma source mass spectrometer (ICP-MS). Apoptosis of renal cell was determined by terminal-deoxynucleoitidyl transferase mediated Nick End Labeling (TUNEL). Renal typeⅢ collagen protein's expression was determined by immunohistochemical (HIC) method and expression changes of MT-1, MT-2 mRNA in kidney were also determined by real-time fluorescence quantitative PCR (real-time-PCR). There was no significant difference of ALT, AST in serum between normal control group and other groups (P>0.05). CREA and UREA in mercurous chloride group were apparently higher than normal control group and low dose group of Meng-Gen-Wu-Su processed products (P<0.01). Hepatic and renal pathologic examination results showed that liver cell of low dose groups ofMeng-Gen-Wu-Su processed products andMeng-Gen-Wu-Su-18-composition pill swelled to a low degree and glomerular disease was not obvious. In high-dose groups ofMeng-Gen-Wu-Su processed products,Meng-Gen-Wu-Su-18-composition pill and mercuric sulfide group, liver and kidney appeared some pathological changes and such changes were more significant in mercuric chloride and mercurous chloride groups. Compared with normal control group and low dose group ofMeng-Gen-Wu-Su processed products, the mercury kidney volume in mercuric chloride and mercurous chloride groups increased significantly (P<0.01). The apoptosis rate of renal cell and expression of typeⅢ collagen protein increased significantly in the groups of mercuric sulfide, mercuric chloride and mercurous chloride (P<0.01). MT-1and MT-2 mRNA gene expression rised significantly in the groups of mercuric chloride and mercurous chloride (P<0.05 orP<0.01). In summary, the rats renal toxicity after a single dose ofMeng-Gen-Wu-Su (Mercury) processed products or MongolianMeng-Gen-Wu-Su (Mercury)-18-composition pill were both far less than that of mercuric chloride or mercurous chloride.

Betel Shi-San-Wei Ingredients Pill(BSSWIP) was first recorded in the 19th century writings Meng-Yi Jin-Gui with the name of Gao-Y ou-13. The name of BSSWIP was first recorded in the book of the 1977 edition of the Drug Standard of the Jilin Province, which was formerly known as Tai De Hu Ran Gu Lu Ge Qi Nai Ran Ta, Se Me Ji De Ji De, and etc. Although in the book of Tong-Wa-Ga-Ji-De, Se Me Ji De Ji De was documented, it was the same name of different compositions. It had no original relation with BSSWIP. In different periods, the BSSWIP was consisted of 13, 14 or 15 kinds of herbs. There were at least five different types of herbs appeared in the Gao-Y ou-13. The evolution of prescription was mainly from the 19th century to the first half of the 20th century. There was no major change on prescription composition and proportion since 1971. Among them, 10 kinds of herbs, which were Bing-Lang, Guang-Zao, Mu-Xiang, Ding-Xiang, Rou-Dou-Kou, Zi-Nao-Sha, Gan-Jiang, Bi-Ba, Hu-Jiao, and Chen-Xiang were fixed. The ratio of single herbal medicine changed the most was Zhi-Cao-W u, which was followed by Mu-Xiang, Ding-Xiang and Chen-Xiang. There were no marked sources of BSSWIP in the recording of the Drug Standard of the Jilin Province and the Mongolian Medicine V olume·Ministry of Health of the People's Republic of China. The composition and proportion were considered to be from the book Meng-Y i Jin-Gui according to notes of Standards on Mongolian Patent Medicine in Inner Mongolia. Recordings of three standards are in consistence with the Meng-Y i Jin-Gui on Gao-Y ou-13 except for Y e-Mao-Niu Xin and the different ratio of Zhi-Cao-W u. In the appendix of the Standards on Mongolian Patent Medicine in Inner Mongolia, it marked the differences from the original prescription. Therefore, the other two criteria should also mark the similarities and differences compared with the original prescription properly.

Sepsis is a critical illness with high morbidity and mortality. Anaerobic glycolysis plays an important role in the pathogenesis of sepsis. Pyruvate dehydrogenase complex (PDHC) serves as a key regulator during sepsis. With PDHC dephosphorylation and deacetylation, PDHC activity is upregulated, allowing pyruvate translocate to mitochondria in aerobic condition, preceding the production of acetyl-CoA to accelerate aerobic oxidation. Activation of PDHC improves the prognosis of sepsis through regulating the balance of lactate, release of inflammatory factors and energy metabolism. A variety of remedies can improve the prognosis of patients with sepsis by up-regulating the activity of PDHC, including dichloroacetate (DCA), vitamin B1, milrinone, tumor necrosis factor binding protein, and ciprofloxacin.This article reviews the role and the regulatory mechanism of PDHC and signal pathway in the sepsis metabolism, in order to innovate treatment for sepsis and multiple organ dysfunction.

Objective:To construct the impact factor model of primary traditional Chinese medicine (TCM) health management service quality, and put forward corresponding policy suggestions.Methods:In this cross-sectional study, the typical sampling and random sampling method were used to select 39 insiders of primary TCM health management service from 15 communities in Zhejiang Province from August to October in 2022. Interviews on service projects, implementation effects and impact factors were conducted, the three-level coding of interview record was carried out using the grounded theory research method, a model of impact factor for health management service quality of basic TCM was constructed, and the corresponding policy recommendations were put forward.Results:Based on the open coding of 39 original interview data, a total of 516 reference points were obtained, and 53 initial concepts related to the topic were formed and summarized into 17 first-level categories. Through the summary of main axis coding, 6 main categories of “policy environment”,“health literacy”,“community orientation”,“capacity building”,“health preference” and “conflict of interest” were extracted. The logical correlation between the six main categories were analyzed with selective coding, an impact factor model was constructed in accordance with the story line of factors affecting service quality. The story line of this model was as follows: first, the policy environment was the external guarantee of community TCM service quality; second, as the demand-side of the services, the health literacy and requirement of residents was the regulatory factor for service quality; in addition, the community played the role of the supply-side of the services, the service ability construction was the key factor, and the community functions and target orientation was the internal driving factor, meanwhile, the internal/external conflicts of interest had a negative constraint on the service quality.Conclusions:The guarantee intensity of external policy environment is limited, the service demand side pays insufficient attention, and the service supply side functions are absent at the present stage. It is necessary to improve the external policy environment, deepen the connection between supply and demand sides in the field of TCM health service, promote the capacity building of TCM service at the grass-roots level, balance the interests of relevant departments of TCM service, in order to improve the quality of TCM health management service at the grass-roots level.

Objective:To study the changes and imaging features of arachnoid granulation (AG) in patients with cerebral venous sinus thrombosis (CVST).Methods:The clinical and imaging data of 35 patients with idiopathic CVST confirmed by MR imaging combined with CE-MRV or DSA in our hospital from January 2013 to December 2018, and 35 healthy controls collected at the physical examination center at the same time period were detected. The sizes and numbers of AG were compared between the two groups, and the MR imaging features of CVST and AG in patients with CVST at different courses were compared.Results:(1) In 35 patients with CVST, AG was found in 14 patients, and the average diameter was (5.19±2.40) mm, ranged from 1.83-11.77 mm; in the control group, AG was found in 23 patients, and the average diameter was (4.45±2.03) mm, ranged from 1.45-9.87 mm; no statistical difference was noted in diameter between the two groups ( t=2.121, P=0.221), and the number of AG showed statistical difference between the two groups (χ 2=4.644, P=0.031). (2) In 8 patients with CVST at acute phase, CVST showed hypointense on T2WI and FLAIR; in 20 patients with CVST at subacute phase, CVST showed hyperintense on T2WI and FLAIR; in 7 patients with CVST at chronic phase, CVST showed hyperintense on T2WI and FLAIR. At any stage of venous sinus thrombosis, AG showed high signal on T2WI and low signal on FLAIR. Conclusion:AG detection rate in CVST patients is lower than that in normal controls; MR imaging T2WI and FLAIR sequences could effectively distinguish CVST with AG.
