This study was aimed to analyze characteristics of Chinese Materia Medica ( CMM ) preparations in order to identify the long-term development direction of this discipline and suggest key questions and strategies to solve the problems. According to the development track of CMM preparation, traditional Chinese medicine (TCM) basic theories and modern new drug research techniques were combined with the author's experiences on modernization study of TCM. This article discussed key issues of CMM preparation development direction, characteristics and is-sues need to be solved and their countermeasures. The results showed that the development direction for CMM preparation discipline should entirety unify CMM preparation system. The medical resource should be convenient which include animal, plant and mineral products. The single determinacy (effectiveness, stability and controlled) and compatibility (prediction, optimization and lowest toxin) will be applied in the guidance of CMM preparation system. In order to achieve goals mentioned above, key issues need to be solved are efficiency categories for in-gredients, genetical stabilities and one sampling charge, emigration rules of properties among ingredients, the ki-netic and stable rules of ingredient extraction, controlled rules for integral models or for disorder and torrent, e-valuation rules in vivo and in vitro, microscopic and macroscopic qualities, determinacy for single administration and compatibility for combination applications. It was concluded that the CMM preparation is a series of integral unified effective ingredient preparations that behave the determinacy for single administration and compatibility for combination applications.

The paper aims to elucidate and establish a new mathematic model: the total quantum statistical moment standard similarity (TQSMSS) on the base of the original total quantum statistical moment model and to illustrate the application of the model to medical theoretical research. The model was established combined with the statistical moment principle and the normal distribution probability density function properties, then validated and illustrated by the pharmacokinetics of three ingredients in Buyanghuanwu decoction and of three data analytical method for them, and by analysis of chromatographic fingerprint for various extracts with different solubility parameter solvents dissolving the Buyanghanwu-decoction extract. The established model consists of four mainly parameters: (1) total quantum statistical moment similarity as ST, an overlapped area by two normal distribution probability density curves in conversion of the two TQSM parameters; (2) total variability as DT, a confidence limit of standard normal accumulation probability which is equal to the absolute difference value between the two normal accumulation probabilities within integration of their curve nodical; (3) total variable probability as 1-Ss, standard normal distribution probability within interval of D(T); (4) total variable probability (1-beta)alpha and (5) stable confident probability beta(1-alpha): the correct probability to make positive and negative conclusions under confident coefficient alpha. With the model, we had analyzed the TQSMS similarities of pharmacokinetics of three ingredients in Buyanghuanwu decoction and of three data analytical methods for them were at range of 0.3852-0.9875 that illuminated different pharmacokinetic behaviors of each other; and the TQSMS similarities (ST) of chromatographic fingerprint for various extracts with different solubility parameter solvents dissolving Buyanghuanwu-decoction-extract were at range of 0.6842-0.999 2 that showed different constituents with various solvent extracts. The TQSMSS can characterize the sample similarity, by which we can quantitate the correct probability with the test of power under to make positive and negative conclusions no matter the samples come from same population under confident coefficient a or not, by which we can realize an analysis at both macroscopic and microcosmic levels, as an important similar analytical method for medical theoretical research.

OBJECTIVE: To analyze the relationship between traditional Chinese medical syndromes and fungal pneumonia for moderate and advanced lung cancer patients. METHODS: We retrospected 115 moderate and advanced lung cancer patients with different syndromes in traditional Chinese medicine (qi deficiency, yin deficiency, blood deficiency, yang deficiency, blood stasis, phlegm dampness, phlegm heat, damp heat, cold dampness, qi stagnation, heat toxin), who had the concurrent fungal pneumonia, and used regression analysis method to analyze the data. RESULTS: When the patients had the phlegm heat syndrome, they got a significantly higher risk of having fungal pneumonia (P < 0.01); and when they had the heat toxin syndrome, they also had a high risk of having fungal pneumonia (P < 0.05). CONCLUSION: The phlegm heat and heat toxin syndromes are the risk factors for moderate and advanced lung cancer patients having concurrent fungal pneumonia.

Methods:
The clinical data of 176 patients with complicated hepatolithiasis who underwent operation at the Department of General Surgery of No.960 Hospital of PLA from May 2005 to July 2015 were analyzed retrospectively. The data included general data, clinical manifestations, types of stones, operative methods, postoperative complications and follow-up.
Results:
There was no perioperative death. The postoperative complications which occurred in 31 patients (17.6%) included lung infection, intra-abdominal infection, bile leakage, and liver failure. Eighteen patients (10.2%) were found to have residual stones. After a follow-up which ranged from 1 to 3 years, 152 patients (94.4%) had good clinical outcomes. Recurrent stones were found in 12 patients (7.5%).
