LI Haisong's Experience in Treating Spermatorrhea based on the View of "Spirit Controlling Essence and Qi" / 中医杂志

This paper summarized Professor LI Haisong's clinical experience in treating spermatorrhea based on the view of "spirit controlling essence and qi". It is emphasized that the heart spirit has the function of controlling the essence and qi of the human body， believing the frenetic stirring of heart spirit and the insecurity of essence gate are the core pathogenesis of spermatorrhea， LI advocates to regulate the heart spirit first and take into account of the zang-fu organs， essence and qi simultaneously for the treatment. Treatment should be performed according the clinical syndromes differentiatied. For those with heart spirit failing to nourish syndrome， it is recommended to supplement heart qi， nourish spirit and consolidate essence with self-made Yangxin Mijing Formula （养心秘精方）. In case of heart fire hyperactivity， the method of clearing heart heat and draining fire， calming spirit and consolidating essence should be used， and self-made Xiexin Gujing Formula （泻心固精方） is recommended. For heart-liver qi constraint， it is advised to soothe the liver and calm heart， calm the mind and regulate essence with self-made Jieyu Anshen Tiaojing Formula （解郁安神调精方） which is a modifcation to Chaihu Shugan Powder （柴胡疏肝散）. In terms of deficiency of both heart and liver， the treatment principle is supplementing spleen and nourishing heart， calming the mind and controlling essence， for which self-made Xinpi Tongtiao Shejing Formula （心脾同调摄精方） modified from Guipi Decoction （归脾汤） can be used. For deficiency of both heart and kidney， it is better to nourish the kidney and calm heart， calm the mind and consolidate essence with self-made Xinshen Liangzi Tianjing Formula （心肾两滋填精方） that modified from Shuilu Erxian Elixir （水陆二仙丹） and Wuzi Yanzong Pill （五子衍宗丸）. Prescriptions are used to treat the root by harmonizing the zang-fu organs， nourish the spirit by regulating qi and blood， and calm the mind by taking special medi-cinals， and they should be flexibly modified according to the disease.

Analysis of ZHANG Cigong's “Dual Diagnosis and Single Treatment” Thoughts on Integrating Traditional Chinese and Western Medicine in Treating Gastric Diseases / 中医杂志

Emphasizing the correspondence between western medicine pathology and traditional Chinese medicine pathogenesis， ZHANG Cigong proposes “dual diagnosis and single treatment”. “Dual diagnosis” refers to the determination of pathology， etiology and disease names in western medicine as well as the syndromes of traditional Chinese medicine （TCM）， while “single treament” is the use of Chinese herbal medicine （CHM）. By analyzing the records of gastric disease cases by ZHANG Cigong and the related discussions， this paper summarized the “dual diagnosis and single treatment” of gastric disease， including the three-step diagnosis logic of gastric disease， the correspondence between pathology and pathogenesis， etiological diagnosis and TCM syndrome differentiation， as well as CHM for the treatment of acute gastritis， gastric ulcer and hyperacidity， duodenal ulcer， chronic gastritis， dyspepsia and gastrointestinal neurosis， and upper gastrointestinal bleeding. Under the thinking mode of organic integration of logical thinking， clinical practice， and scientific research， he corresponded the basic concepts of “Qi and blood， cold and hot， warm and cool” to “substance and function” in traditional Chinese and western medicine， exploring the essence of interoperability between Chinese and Western medicine， thereby expanding the scope of TCM syndrome differentiation and its efficacy to the microscopic physiological and pathological level. It is believed that ZHANG Cigong's academic ideas provide reference to the “win-win” approach of modern integration between Chinese and western medicine， and should follow the premise of learning from each other's strengths and complementing each other to fully highlight their advantages.

Diverse genetic spectrum among patients who met the criteria of hereditary breast, ovarian and pancreatic cancer syndrome / 부인종양

Objective@#Genetic high-risk assessment combines hereditary breast, ovarian and pancreatic cancer into one syndrome. However, there is a lack of data for comparing the germline mutational spectrum of the cancer predisposing genes between these three cancers. @*Methods@#Patients who met the criteria of the hereditary breast, ovarian and pancreatic cancer were enrolled and received multi-gene sequencing. @*Results@#We enrolled 730 probands: 418 developed breast cancer, 185 had ovarian cancer, and 145 had pancreatic cancer. Out of the 18 patients who had two types of cancer, 16 had breast and ovarian cancer and 2 had breast and pancreatic cancer. A total of 167 (22.9%) patients had 170 mutations. Mutation frequency in breast, ovarian and pancreatic cancer was 22.3%, 33.5% and 17.2%, respectively. The mutation rate was significantly higher in patients with double cancers than those with a single cancer (p<0.001). BRCA1 and BRCA2 were the most dominant genes associated with hereditary breast and ovarian cancer, whereas ATM was the most prevalent gene related to hereditary pancreatic cancer. Genes of hereditary colon cancer such as lynch syndrome were presented in a part of patients with pancreatic or ovarian cancer but seldom in those with breast cancer. Families with a history of both ovarian and breast cancer were associated with a higher mutation rate than those with other histories. @*Conclusion@#The mutation spectrum varies across the three cancer types and family histories. Our analysis provides guidance for physicians, counsellors, and counselees on the offer and uptake of genetic counseling.

Research progress on synthesis, safety, function and mechanism of selenium nanoparticles / 中国药理学通报

As an essential trace element, selenium plays a very important role in antioxidation and maintaining redox homeostasis in various metabolic processes. With the development of nano-technology, selenium nanoparticles ( SeNPs) have become potential biomedical drugs because of their low toxicity, degrad-ability and high bioavailability. With the ability to activate apop-tosis or autophagy by regulating the production of reactive oxygen species ( ROS) , SeNPs are widely used in anticancer therapy and pathogens killing/clearance. In addition, with excellent stability and drug encapsulation capacity, SeNPs are serving as a kind of effective nano-carriers for anti-cancer and anti-infection treatments. Interestingly, the important role of SeNPs in immune regulation ( such as the activation of macrophages and T effector cells) provides a new possibilities to achieve nano-immune syn-ergetic treatment strategy for anti-cancer and anti-infection thera¬pies. In this paper, we review the latest progress of the prepara¬tion methods and safety for SeNPs, followed by the advances of anti-infection, anti-cancer effects and its mechanisms, which would be helpful for promoting the pace of clinical research and application. In addition, we also summarize the functions of SeNPs in other aspects, so as to provide beneficial assistance for facilitating its scientific and clinical research.

Pathogenicity evaluation and splicing correction of COL4A5 splice mutation in X-linked Alport syndrome / 中华肾脏病杂志

Objective:To analyze the splicing mutation site of COL4A5 gene in a family with X-linked dominant Alport syndrome and explore the possibility of exon specific U1 small nuclear RNA (snRNA) gene therapy. Methods:The clinical data of the proband and family members of Alport syndrome were collected, and the gene mutations in the whole exon of a series of nephropathy genes in the proband were detected by high-throughput sequencing. The splice site changes and pathogenicity caused by COL4A5 c.546+5G>A mutation were analyzed by online software. Minigene experiment was used to verify and analyze the effect of COL4A5 gene mutation site c.546+5G>A in the proband of Alport syndrome family, and transient transfection and introduction of modified U1 snRNA to correct splicing mutation. Results:The results of gene sequencing showed that there was a hemizygous variation of COL4A5 gene in the proband and his half brother, and the variation site was c.546+5G>A. The results of online software for analyzing the pathogenicity of splice variation showed that the original donor splicing site could not be detected after mutation, suggesting that there was a great possibility of affecting splicing. The abnormal splicing mode of COL4A5 gene with c.546+5G>A mutation—deletion of exon 9 was verified by hybridized small gene detection. The abnormal splicing mutation could be partially corrected by the modified U1 snRNA. The correction ratios of ExSpeU1 (MT), ExSpeU1(E9+1), ExSpeU1(E9+9) and ExSpeU1(E9+11) to exon 9 deletion caused by c.546+5G>A were 0, 43.81%, 52.09% and 48.12%, respectively. Conclusions:The pathogenicity of the new splicing mutation of COL4A5 is verified, and the modified U1 snRNA can partially correct the abnormal splicing.

Mechanism of inhibiting proliferation of tumor cells by a new tetrahydroisoquinoline compound SYT-1 / 药学学报

In this study, we investigated the inhibitory effect of SYT-1, a new compound of tetrahydroisoquino-line, on tumor cell proliferation and underlying mechanisms. Cell counting kit-8 (CCK-8) method was used to detect cell proliferation; clone formation experiment was used to detect cell clone formation ability; JC-1 probe was used to detect cell mitochondrial membrane potential; 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) probe was used to detect intracellular reactive oxygen species; Annexin V-FITC/PI (fluorescein isothiocyanate/propidium) counterstaining method was used to detect apoptosis; Western blot assay was used to detect the expression level of related proteins. The experimental results show that SYT-1 has a significant inhibitory effect on the proliferation of six human-derived cancer cells. Among them, the inhibitory effect on breast cancer MCF-7 cells is the strongest, the half maximal inhibitory concentration (IC50) of SYT-1 of 48 h administration on MCF-7 cells is 5.87 μmol·L-1, which is better than that of cisplatin (8.92 μmol·L-1). Further studies have shown that SYT-1 can dose-dependently inhibit the monoclonal formation ability of MCF-7 cells, and can cause the mitochondrial membrane potential of the cells to decrease and the level of reactive oxygen species to increase. In addition, SYT-1 can significantly inhibit the activation of PI3K-Akt (phosphatidylinositol 3-kinase/protein kinase B) signaling pathway and induce apoptosis of MCF-7 cells. The above research results show that, as a new type of tetrahydroisoquinoline compound, SYT-1 has the potential to inhibit tumor cell proliferation.

Sofosbuvir/velpatasvir plus ribavirin for Child-Pugh B and Child-Pugh C hepatitis C virus-related cirrhosis

Background/Aims@#Real-world studies assessing the effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) plus ribavirin (RBV) for Child-Pugh B/C hepatitis C virus (HCV)-related cirrhosis are limited. @*Methods@#We included 107 patients with Child-Pugh B/C HCV-related cirrhosis receiving SOF/VEL plus RBV for 12 weeks in Taiwan. The sustained virologic response rates at off-treatment week 12 (SVR12) for the evaluable population (EP), modified EP, and per-protocol population (PP) were assessed. Thesafety profiles were reported. @*Results@#The SVR12 rates in the EP, modified EP and PP were 89.7% (95% confidence interval [CI], 82.5–94.2%), 94.1% (95% CI, 87.8–97.3%), and 100% (95% CI, 96.2–100%). Number of patients who failed to achieve SVR12 were attributed to virologic failures. The SVR12 rates were comparable regardless of patient characteristics. One patient discontinued treatment because of adverse events (AEs). Twenty-four patients had serious AEs and six died, but none were related to SOF/VEL or RBV. Among the 96 patients achieving SVR12, 84.4% and 64.6% had improved Child-Pugh and model for endstage liver disease (MELD) scores. Multivariate analysis revealed that a baseline MELD score ≥15 was associated with an improved MELD score of ≥3 (odds ratio, 4.13; 95% CI, 1.16–14.71; P=0.02). Patients with chronic kidney disease (CKD) stage 1 had more significant estimated glomerular filtration rate declines than patients with CKD stage 2 (-0.42 mL/min/1.73 m2/month; P=0.01) or stage 3 (-0.56 mL/min/1.73 m2/month; P<0.001). @*Conclusions@#SOF/VEL plus RBV for 12 weeks is efficacious and well-tolerated for Child-Pugh B/C HCV-related cirrhosis.

Method:The purity of seeds of <italic>B. chinensis</italic> from different producing areas was analyzed，and the 1 000-grain weight，water content，viability and germination rate of seeds of <italic>B. chinensis</italic> with different diameters were determined after diameter classification. K-means was used for cluster analysis to preliminarily formulate the quality grading standard of seeds of <italic>B. chinensis</italic>. Result:There were obvious regional differences in the size of seeds of <italic>B. chinensis</italic>. The particle size of seeds of <italic>B. chinensis</italic> of Xiaochang，Dawu and Huanggang Academy of Agricultural Sciences in Hubei Province was larger and mostly between 4.5 mm to 5.5 mm. The seeds of<italic> B. chinensis </italic>from Tuanfeng，Qujing，Yunnan，and Anguo，Hebei province had smaller particle sizes than those from the other three producing areas，which were mostly between 3.5 mm to 5.0 mm. Arils in seeds of <italic>B. chinensis</italic> were removed by 10% NaClO to effectively break seed dormancy and significantly improve the seed germination rate. On this basis，the seed diameter was taken as the main grading index，and the seed moisture content，viability，germination rate and purity were taken as important reference indexes. The quality of seeds of <italic>B. chinensis</italic> was preliminarily divided into three grades，grade Ⅰ：seed diameter≥5.5 mm，moisture content≤10%，viability≥94%，germination rate≥60%，and cleanliness≥93%；grade Ⅱ：seed diameter≥4.5 mm，moisture content≤10%，viability≥90%，germination rate≥55%，and cleanliness≥85%；and grade Ⅲ：seed diameter≥3.5 mm，moisture content≤10%，viability≥84%，germination rate≥45%，cleanliness≥80%. Conclusion:In this study，the quality grading standard of seeds of <italic>B. chinensis</italic> was preliminarily established to provide reference for the quality evaluation of seeds of <italic>B. chinensis</italic> and the breeding of improved varieties. In addition，the maturity and the storage time of seeds of <italic>B. chinensis</italic> have a greater impact on the quality of seeds，so it is recommended to select fully mature（dark black） seeds and new seeds for production.
