OBJECTIVE To provide reference for improving resource carrying capacity of pharmaceutical industry and guaranteeing the healthy and sustainable development of pharmaceutical industry of China. METHODS The evaluation system of resource carrying capacity was constructed ，including 4 primary indicators and 17 secondary indicators. The data of above indicators were selected from 31 provinces（autonomous regions and municipalities ）（hereinafter referred to as provinces ）of China during 2013-2020. The index weight and regional relevance were calculated by entropy weight technique for order preference by similarity to ideal solution（TOPSIS）method. RESULTS & CONCLUSIONS The weights of 4 primary indicators were 0.182 0 （industrial scale ），0.349 5（industrial innovation resources ），0.211 5（economic resources ）and 0.257 1（industrial development foundation）. It indicated that industrial innovation resources were the main factor affecting the resource carrying capacity of pharmaceutical industry ，followed by industrial development foundation and economic resources ，and the impact of industrial scale was the least. From 2013 to 2016 and from 2018 to 2020，the average closeness of the pharmaceutical industry in China ’s provinces were 0.259 6，0.267 1，0.253 6，0.249 9，0.250 5，0.248 5 and 0.252 0，respectively. It indicated that the resource carrying capacity of China ’s pharmaceutical industry showed a stable development trend ，but the overall development was in low level. The top 5 regions in terms of closeness of carrying capacity were Jiangsu ，Guangdong，Shandong，Zhejiang and Beijing ；the regions in the bottom 5 were Gansu ，Hainan，Qinghai，Tibet and Ningxia. Overall ，the resource carrying capacity of China ’s pharmaceutical industry showed a gradual decreasing trend from the eastern coastal area to the western inland area. For the provinces with the highest resource carrying capacity of pharmaceutical industry ，further development can be carried out on the basis of maintaining the original carrying capacity ；for the provinces with the middle resource carrying cap acity of p harmaceutical industry ，enhancing the development potential and improving the industrialfoundation are the main methods to improve the resource carrying capacity of pharmaceutical industry ；for the provinces wangjl@126.com with low resource carrying capacity of pharmaceutical industry ， it can be considered to start from their own unique advantages ， make full use of characteri stic industrial resources ，form a characteristic industrial foundation ，actively promote interregional cooperation ，implement regional cluster development and improve the resource carrying capacity of pharmaceutical industry.

The field of gene therapy has been increasingly studied in the last four decades, and its clinical application has become a reality in the last 15 years. Traditional Chinese medicine (TCM), an important component of complementary and alternative medicine, has evolved over thousands of years with its own unique system of theories, diagnostics and therapies. TCM is well-known for its various roles in preventing and treating infectious and chronic diseases, and its usage in other modern clinical practice. However, whether TCM can be applied alongside gene therapy is a topic that has not been systematically examined. Here we provide an overview of TCM theories in relation to gene therapy. We believe that TCM theories are congruent with some principles of gene therapy. TCM-derived drugs may also act as gene therapy vehicles, therapeutic genes, synergistic therapeutic treatments, and as co-administrated drugs to reduce side effects. We also discuss in this review some possible approaches to combine TCM and gene therapy.

OBJECTIVEIn the present study, we systemically evaluated the ability of two bioactive compounds from traditional Chinese medicine, celastrol and pristimerin, to enhance recombinant adeno-associated virus (rAAV) serotype vector-mediated transgene expression both in human cell lines in vitro, and in murine hepatocytes in vivo.

METHODSHuman cell lines were infected with rAAV vectors with either mock treatment or treatment with celastrol or pristimerin. The transgene expression, percentage of nuclear translocated viral genomes and the ubiquitination of intracellular proteins were investigated post-treatment. In addition, nonobese diabetic/severe combined immunodeficient gamma (NSG) mice were tail vain-injected with rAAV vectors and co-administered with either dimethyl sulfoxide, celastrol, pristimerin or a positive control, bortezomib. The transgene expression in liver was detected and compared over time.

RESULTSWe observed that treatment with pristimerin, at as low as 1 μmol/L concentration, significantly enhanced rAAV2 vector-mediated transgene expression in vitro, and intraperitoneal co-administration with pristimerin at 4 mg/(kg·d) for 3 d dramatically facilitated viral transduction in murine hepatocytes in vivo. The transduction efficiency of the tyrosine-mutant rAAV2 vectors as well as that of rAAV8 vectors carrying oversized transgene cassette was also augmented significantly by pristimerin. The underlying molecular mechanisms by which pristimerin mediated the observed increase in the transduction efficiency of rAAV vectors include both inhibition of proteasomal degradation of the intracellular proteins and enhanced nuclear translocation of the vector genomes.

CONCLUSIONThese studies suggest the potential beneficial use of pristimerin and pristimerin-containing herb extract in future liver-targeted gene therapy with rAAV vectors.

OBJECTIVELittle effort has been made to study the protein-encoding genes isolated from traditional Chinese medicine (TCM) drugs, and the delivery of these genes into malignant cells through recombinant adeno-associated virus (rAAV) vectors has not been attempted.

METHODSWe synthesized the cDNAs of five known cytotoxic proteins isolated from TCM drugs and the FLAG epitope-tagged cDNAs were subcloned into a rAAV plasmid vector. The protein expression was confirmed by Western blot assay. Various cancer cell lines were transfected with the above plasmids and cell growth was monitored both in vitro and in vivo. The best cytotoxic gene was further packaged into rAAV vectors, under the control of a liver cancer-specific promoter. The liver tumor growth was then monitored following intratumor administration of the rAAV vectors.

RESULTSThe expression plasmids, encoding individual potential cytotoxic genes tagged with FLAG epitope, were successfully generated and sequenced. Among these genes, trichosanthin (TCS) gene yielded the most promising results for the inhibition of cancer cell growth in vitro. The over-expressed TCS functioned as a type I ribosome-inactivating protein, followed by inducing apoptosis that is associated with the Bcl-PARP signaling pathway. Furthermore, intratumor injection of rAAV vectors containing the TCS gene significantly inhibited the growth of human hepatocellular carcinoma tumors in a murine xenograft model.

CONCLUSIONOur studies suggest that the use of TCM cytotoxic genes is a useful therapeutic strategy for treating human cancers in general, and liver tumors in particular.
