OBJECTIVETo analyze costs of the traditional Chinese medicine industry focusing on production costs.

METHODData of 50 planted Chinese herbal medicines and 50 wild Chinese herbal medicines were summarized and analyzed to see the changes of price of Chinese herbal medicines.

RESULTThe derivative problems of limited price were analyzed by crude drug, quality of Chinese medicine and sustainable utilization of resource.

CONCLUSIONThe price of Chinese medicine shall be adapted to sustainable development of market economy.

OBJECTIVETo probe into the new idea along with establishment of a novel method for dynamic monitoring and early-warning on the wild resources of traditional Chinese medicines (TCMs).

METHODThe alterations of wild traditional Chinese medicinal resources were assessed through the price ratio between drug and foodstuff (PRDF) indicating the balance between supply and demand of the specific TCMs, referred to the price ration between pork to foodstuff which is used in national monitoring to the balance between pork supply and demand.

RESULTSince the price of rice was tightly controlled by government, it was selected as a relatively stable reference to build the PRDF in order to take away the non-marketing influence to TCMs price such as CPI and inflation rate. The modified relative alteration trend of TCMs price had been researched through comparing different formulae to build PRDF, including absolute average month price of TCMs, month average price ratio of TCMs to foodstuff (rice) , month-on-month change of TCMs to rice, year-on-year change of TCMs to rice, and difference in value of period-on-period change (DVPPC). In the research, Cordyceps, Glycyrrhiza and totally five herbs were selected as model drugs and the price data were collected from 2002 to 2008. The results showed that DVPPC calculated of relative long time window was more sensitive and stable to reflect the relative alteration trend of TCMs price. For instance, the DVPPC of Ligustici showed continuously increase trend in recent years. This suggested appearance of unbalance between supply and demand of Ligustici, and forced policy intervention to maintain reasonable and continuable utilization of Ligustici resource.

CONCLUSIONThe proposed method and the formula of DVPPC revealed some useful guidance for dynamic monitoring the wild resources of TCMs.

Objective:To explore the short-term and long-term prognostic outcomes of anatomical liver resection(AR)for patients with perihilar cholangio-carcinoma. Methods:This is a retrospective study.All data were obtained from 4 centers,including The First Affiliated Hospital of Army Medical University,Eastern Hepatobiliary Hospital of Naval Medical University,Sichuan Provincial People's Hospital and Affiliated Hospital of Qinghai University,of a multi-center database.A total of 305 consecutive perihilar cholangiocarcinoma patients receiving radical resection between January 2013 and June 2021 were included in this study.According to the method of liver resection,all patients were divided into the AR group(n=205)and the non-anatomical liver resection(NAR)group(n=100).The baseline characteristics,short-term prognosis and long-term prognosis of the 2 groups were compared. Results:The perioperative transfusion rate and the 30-day complication rate were significantly lower in the AR group than those in the NAR group(P＜0.05).There was no statistically significant difference in the survival rates between the AR and the NAR groups(P＞0.05). Conclusion:The 2 hepatic resection modalities had no obvious effect on the long-term prognosis of perihilar cholangiocarcinoma patients after radical resection,but choosing AR tends to achieve a better short-term prognosis and is worth promoting in clinical practice.
