Under the guidance of the theory of traditional Chinese medicine (TCM), charcoal drugs are widely used in clinical treatment of various bleeding syndromes, in addition, they also have the effect in anti-diarrhea and anti-ulcer, but charcoal drugs are especially effective in stopping bleeding. According to the changes in the properties after processing, the hemostatic effect of charcoal drugs can be roughly divided into two categories. One is not used for hemostasis itself, but used for hemostasis after processing. The other is used for hemostasis itself, and the drug properties are changed or the hemostatic ability is enhanced after processing. By summarizing researches on historical evolution, processing mechanism and pharmacological effects of the commonly used hemostatic charcoal drugs, the author found that preservation or increase of active substances after processing was closely related to the hemostatic effect of charcoal drugs. The hemostatic mechanism mainly involves the influence of coagulation system and platelet function, etc. At the same time, combined with the theory of Qi chromatograph of TCM supramolecular, this paper puts forward the supramolecular research strategy on hemostatic mechanism of charcoal drugs, in order to provide reference for revealing the scientific connotation of charcoal drugs for hemostasis.

OBJECTIVE:
To investigate the current status of antibiotic use for very and extremely low birth weight (VLBW/ELBW) infants in neonatal intensive care units (NICUs) of Hunan Province.
METHODS:
The use of antibiotics was investigated in multiple level 3 NICUs of Hunan Province for VLBW and ELBW infants born between January, 2017 and December, 2017.
RESULTS:
The clinical data of 1 442 VLBW/ELBW infants were collected from 24 NICUs in 2017. The median antibiotic use duration was 17 days (range: 0-86 days), accounting for 53.0% of the total length of hospital stay. The highest duration of antibiotic use was up to 91.4% of the total length of hospital stay, with the lowest at 14.6%. In 16 out of 24 NICUs, the antibiotic use duration was accounted for more than 50.0% of the hospitalization days. There were 113 cases with positive bacterial culture grown in blood or cerebrospinal fluid, making the positive rate of overall bacterial culture as 7.84%. The positive rate of bacterial culture in different NICUs was significantly different from 0% to 14.9%. The common isolated bacterial pathogens Klebsiella pneumoniae was 29 cases (25.7%); Escherichia coli 12 cases (10.6%); Staphylococcus aureus 3 cases (2.7%). The most commonly used antibiotics were third-generation of cephalosporins, accounting for 41.00% of the total antibiotics, followed by penicillins, accounting for 32.10%, and followed by carbapenems, accounting for 13.15%. The proportion of antibiotic use time was negatively correlated with birth weight Z-score and the change in weight Z-score between birth and hospital discharge (r=-0.095, -0.151 respectively, P<0.01), positively correlated with death/withdrawal of care (r=0.196, P<0.01).
CONCLUSIONS
Antibiotics used for VLBW/ELBW infants in NICUs of Hunan Province are obviously prolonged in many NICUs. The proportion of routine use of third-generation of cephalosporins and carbapenems antibiotics is high among the NICUs.

Yangjing Zhongyu Tang, from FU Qing-zhu Nvke, is a famous classical formula of clinical value for treating blood deficiency syndrome of female infertility in the Qing dynasty. The prescription seems plain, but it is rigorous and effective with high research value. In this paper, the ancient books and modern documents of Yangjing Zhongyu Tang were analyzed from the aspects of traceability of Chinese materia medica in the formula, pharmacological research, clinical research, etc. It could be concluded that the pharmacological studies of this formula were mostly to investigate the mechanism and efficacy of its treatment for infertility, but there was a lack of comprehensive interpretation of the structure, function and principle of pharmacodynamic substance in this formula. In this paper, combined with the contents of supramolecular imprinting template and network pharmacology, the new direction of pharmacological research of Chinese medicine compound was put forward. Quality control of Yangjing Zhongyu Tang mostly based on small molecule compounds, so it was suggested to break the inherent thinking, and increase the detection of macromolecule compounds and supramolecular of Chinese materia medica. The druggability of this formula involved in the preliminary study of decoctions, plasters and granules. Considering the quality stability of Chinese materia medica in the formula and the scientificity of druggability of this formula, the compatibility principle of traditional Chinese medicine (TCM) and modern supramolecular chemistry theory could be combined to study the change law of druggability of TCM before and after compatibility, so as to provide new reference materials for the follow-up clinical application and development of Yangjing Zhongyu Tang.

This paper discussed the processing methods of Pinelliae Rhizoma in the successive dynasties by consulting ancient and modern books, literature and related codes. The processing methods of Pinelliae Rhizoma has experienced various historical periods. Since the processing method of Pinelliae Rhizoma processed by slicing appeared in the Huangdi Neijing, there have been a series of different processing methods and requirements are founded, such as cleansing, cutting, decocting and so on. Among them, the raw Pinelliae Rhizoma, Pinelliae Rhizoma Praeparatum, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, Pinelliae Rhizoma Praeparatum cum Alumine are still in use today and are widely used. However, there are differences in the processing methods, accessories and their dosages of these various processed products in different dynasty. The processing technology and quality standard of Pinelliae Rhizoma need to be further standardization.

Objective: Based on the analysis of the total components of fingerprint and the determination methods of the existing components in the 2015 edition of Chinese Pharmacopoeia, the "point-line-surface" quality standard of Yangjing Zhongyu Tang was established by the "point" of each single component (morroniside, loganin, paeoniflorin, ferulic acid and verbascoside) to the "line" of multicomponent and the "face" of fingerprint of the whole component. Method: XB-C18 column (4.6 mm×250 mm, 5 μm) was used for gradient elution of 0.1% phosphoric acid aqueous solution-acetonitrile. The column temperature was 30℃, the injection volume was 10 μL, the flow rate was 1.0 mL·min-1, and the detection wavelengths were 240, 316, 230, 334 nm. The contents of these five components in Yangjing Zhongyu Tang were determined by three correction methods, external standard method and regression equation method. At the same time, the fingerprint of Yangjing Zhongyu Tang were analyzed by total component analysis and similarity evaluation. Result: With ferulic acid as reference, the relative correction factor (f) of morroniside, loganin, paeoniflorin and verbascoside were 0.392 1, 0.421 4, 0.261 7, 0.268 6 by multi-point correction method, and their f (slope correction method) were 0.385 4, 0.419 4, 0.255 9, 0.274 0, respectively. Twenty characteristic peaks of fingerprint were analyzed and the similarity was ≥ 0.999.There was no significant difference in the contents of these five components from Yangjing Zhongyu Tang determined by the quantitative assay of multi-components by single-marker (QAMS) correction method, the external standard method and the regression equation method. Conclusion: The comprehensive quality standard established by the total component analysis of fingerprint combined with various determination methods of existing components in the 2015 edition of Chinese Pharmacopoeia has been validated in famous classical formula of Yangjing Zhongyu Tang, which can provide ideas and methods for the quality control with quantitative determination and fingerprint of other famous classical formulas.

Based on the characteristics of biological supramolecules and the law of " imprinting template",the research status and common problems in " maintaining medicinal properties after carbonisatus" in traditional Chinese medicine( TCM) were analyzed,and the further countermeasures were put forward. According to the historical evolution of " maintaining medicinal properties after carbonisatus" in TCM processing,the origin of its common problems was clarified by using the theory of biosupramolecular chemistry. TCM is a megacomplex biological supramolecular system,so TCM processing is just the processing of megacomplex biological supramolecular system,and its essence is a TCM pharmaceutical technology with chemical changes in host and guest of biological supramolecular system with or without adjuvant material under high temperature and humidity. In this study on pharmaceutical technology,host molecule was destructed in the process of carbonizing,but guest molecule was retained. The changing law of the host and guest molecule was controlled by the " imprinting template",which was reflected in the degree of change in the drug properties and efficacy of the decoction pieces. Supramolecular chemistry ran through the whole process,and the " imprinting template" of charcoal medicine was characterized by the supramolecular topological structure characteristics and imprinting behavior. After being combined with the quantitative mathematical model of heating degree in processing,it can realize the accurate processing of " maintaining medicinal properties after carbonisatus" from the source,quantitatively control the quality of carbonic herbs,and formulate stable and controllable quality standards.

We assessed the role of diabetes mellitus (DM) on treatment effects in drug-susceptible initial pulmonary tuberculosis (PTB) patients. A prospective study was conducted in eight provinces of China from October 2008 to December 2010. We enrolled 1,313 confirmed drug-susceptible initial PTB patients, and all subjects received the treatment regimen (2H3R3E3Z3/4H3R3) as recommended by the national guidelines. Of the 1,313 PTB patients, 157 (11.9%) had DM; these patients had more sputum smear-positive rates at the end of the second month [adjusted odds ratios (aOR) 2.829, 95% confidence intervals (CI) 1.783-4.490], and higher treatment failure (aOR 2.120, 95% CI 1.565-3.477) and death rates (aOR 1.536, 95% CI 1.011-2.628). DM was a contributing factor for culture-positive rates at the end of the second month and treatment failure and death of PTB patients, thus playing an unfavorable role in treatment effects of PTB.

The objective of this prospective study of the risks of treatment failure in patients with drug-susceptible pulmonary tuberculosis (PTB) was to provide reference data to help develop a disease control strategy. Participants were recruited in eight provinces of China from October 2008 to December 2010. A total of 1447 patients with drug-susceptible PTB and older than 15 years of age were enrolled. Demographic characteristics, bacteriological test results, and patient outcome, i.e., cure or treatment failure were recorded and compared using the chi-square or Fisher's exact tests. Multivariate logistic regression was used to identify factors associated with risk of treatment failure. Of the 1447 patients who were enrolled, 1349 patients (93.2%) were successfully treated and 98 (6.8%) failed treatment. Failure was significantly associated with age 365 years [odds ratio (OR)=2.522, 95% confidence interval (CI): (1.097-5.801)], retreatment [OR=2.365, 95% CI: (1.276-4.381)], missed medicine [OR=1.836, 95% CI: (1.020-3.306)], treatment not observed [OR=1.879 95% CI: (1.105-3.195)], and positive culture result after the first [OR=1.971, 95% CI: (1.080-3.597)] and second month [OR=4.659, 95% CI: (2.590-8.382)]. The risk factors associated with treatment failure were age 365 years, retreatment, missed medication, treatment not observed, and positive culture at the end of month 1 or month 2. These risk factors should be monitored during treatment and interventions carried out to reduce or prevent treatment failure and optimize treatment success.

Controlled sustained-release preparation (CSRP) is a definitely important source of innovative medicines, however, its further researches and development are limited due to the complexity of Chinese medicine (CM) compositions, and a series of unclear key problems like the apparent properties from physical and chemical aspects. Combined with the CM characteristics of the multiple components and synergistic effect, a series of bottleneck problems in the preparation of CSRP were analyzed. Then the mechanism and influences of supermolecular chemical theory in the CSRP about the multiple-components overall-control were explored under the guideline of "overall control, synchronous dissolution" in CSRP, based on the previous explications about supramolecular chemistry theories and with the application of single component precision controlling technologies. The supermolecular mechanism of multi-component overall control and synchronous release of the CSRP was investigated, providing an useful academic reference for the research and development of the CSRP and laying the theoretical and technical foundation for the manufacturing process of CSRP.
