Chinese Traditional and Herbal Drugs 2020;51(17):4598-4604
Based on the International Patent Classification (IPC) A61P, this paper analyzes the distributional therapeutic situation of Chinese materia medica (CMM) in China dynamically and statically from the perspective of invention patent, then the list of 10 groups of A61P with the largest amount of invention patents application and effective amount is compared with the list of high mortality diseases in China, so as to verify the idea whether the R&D focus of CMM is on high mortality diseases, and put forward suggestions for the R&D directions and strategies of CMM in the treatment of high mortality diseases. The research finds that the R&D of CMM mainly focuses on treating high mortality diseases, except for the malignant tumors and mental disorders. In addition, the intellectual achievement of CMM in the treatment of digestive system diseases is the dominant direction. Under the background of internationalization and standardization of CMM, China needs to strengthen the R&D investment direction of CMM in the treatment of malignant tumors, mental disorders and other fields. The quantity and quality advantages of CMM in the treatment of digestive system diseases will be of significance, thus it needs to actively carry out patent distribution abroad. The role of technical evaluation in the cultivation of high-quality and high-value patents should be attached importance.

Objective:To investigate the expression of microRNA-324-5p (miR-324-5p) and transcription factor forkhead box C1 (FOXC1) in glioma and their relationship with the prognosis of patients.Methods:From March 2012 to March 2015, a total of 72 cases of glioma tissues were collected from glioma patients who were admitted to Chongqing Hygeia Tumor Hospital and the People's Hospital of Nanchuan in Chongqing, and 28 cases of normal human brain tissues resected in craniocerebral surgery were also collected. The expressions of miR-324-5p and FOXC1 mRNA were detected by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR), and the expression of FOXC1 protein was detected by immunohistochemistry. Pearson method was used to analyze the correlation between the expressions of miR-324-5p and FOXC1 in glioma tissues; Kaplan-Meier method was used to analyze the survival of patients with glioma; Cox regression analysis was used to analyze the risk factors affecting the prognosis of patients with glioma.Results:FOXC1 protein was mainly located in the cytoplasm of glioma, and its positive expression rate in glioma tissues was 81.94% (59/72), which was significantly higher than that in normal brain tissues [17.86% (5/28)], and the difference was statistically significant ( χ2 = 35.938, P<0.01). Compared with normal brain tissues, the expression of miR-324-5p was down-regulated in glioma tissues (0.62±0.19 vs. 0.98±0.02, t = 9.974, P < 0.05), and the expression of FOXC1 mRNA was up-regulated (1.41±0.29 vs. 0.99±0.02, t = 7.633, P < 0.05). The expressions of miR-324-5p and FOXC1 protein were correlated with the number of primary lesions, differentiation degree, TNM stage and lymph node metastasis of glioma (all P<0.05). Pearson analysis showed that the expressions of miR-324-5p and FOXC1 mRNA were negatively correlated ( r = -0.550, P<0.01). The 5-year overall survival rate of patients in miR-324-5p high-expression group was significantly higher than that of patients in miR-324-5p low-expression group (45.71% vs. 24.33%, χ2 = 6.531, P = 0.011), and the 5-year overall survival rate of patients in FOXC1 protein high-expression group was significantly lower than that of patients in FOXC1 protein low-expression group (30.41% vs. 42.34%, χ2 = 3.631, P = 0.047). Multivariate Cox regression analysis showed that low differentiation, TNM stage Ⅲ-Ⅳ, lymph node metastasis, low expression of miR-324-5p and high expression of FOXC1 protein were independent risk factors for prognosis of glioma patients (all P < 0.05). Conclusions:The expression of miR-324-5p is low and the expression of FOXC1 is high in glioma. They may be involved in the regulation of tumor differentiation and metastasis, and related to the poor prognosis of patients. They may be potential therapeutic targets for glioma.

In order to explore the dormancy physiological and biochemical mechanism of Paris seeds, the seed embryo growth courses, and the dynamic change of 5 enzymes, include SOD, POD, CAT, MDH, G-6-PDH were measured during variable temperature stratification. The results indicated that Paris seeds embryo grew quickly after 40 d in warm-stratification (18 ± 1) °C, at the meantime the metabolic activity was significantly strengthened. These facts showed that Paris seeds turned into physiological after-ripening process. After 60-80 d, the morphological embryo after-ripping process basically completed, and the following cold-stratification (4 ± 1) °C furthered Paris seed to finish physiological after-ripening. After 40 d, the activity of MDH decreased while G-6-PDH increased significantly. This showed that the main respiratory pathway of seed changed from TCA to PPP, which benifited breaking seed dormancy. In the whole period of stratification process, the activity variation of SOD and CAT was insignificantly and the activity of POD was enhanced significantly after shifting the seed in cold stratification process. This showed that SOD, CAT had no direct effects on breaking Paris seed dormancy but keeping the seed vigor, while the POD might involve in the process of Paris seed dormancy breaking.

A cDNA fragment locating at the putative envelop protein 2(E2) region of GBV-C/HGV fused with Schistosoma japonicum, glutathione S-transferase(GST) was amplified with PCR from plasmid pGEX-E2. The amplified DNA fragment was inserted into plasmid pGEX-5X-1, at the downstream of the coding sequences of GST, in the same reading frame with the gene of GST. The fusion gene fragment of GST-E2 was amplified with PCR, using the recombinant plasmid pGEX-5X-1-E2 as the template. The amplified 1324 bp DNA fragment of GST-E2 was inserted into Pichia pastoris expression vector pPIC9K in reading frame with alpha-factor secreting signal peptide. The plasmid pPIC9K-GST-E2 was transformed into Pichia pastoris GS115 with electroporation. The transformants (His+ Muts) were selected and induced to express the 54kD GST-E2 fusion protein, which could be specially recognized by both the antisera directed against E2 and against GST. The GST-E2 fusion protein was purified with Sepharose 4B glutathione affinity chromatography to a purity of 95%. The expression was optimized to achieve the highest expression level of GST-E2 fusion protein which was accumulated up to 50% of total proteins in the culture supernatant. The GST-E2 protein derived from the recombinant Pichia pastoris was proved possessing antigenicity and high specificity by ELISA, probed with sera from the patients infected by GBV-C/HGV.

BACKGROUNDAssociations between glutamine (Gln) enriched nutrition support and surgical patients with gastrointestinal (GI) tumor remain controversy. The purpose of this meta-analysis was to assess the effect of Gln enriched nutrition support on surgical patients with GI tumor in term of relevant biochemical indices, immune indices, and clinical outcomes.
METHODSSix databases were systematically searched to find eligible randomized controlled trials (RCTs) from 1966 to May 2014. When estimated the analysis indexes, the relative risk (RR) was used as the effect size of the categorical variable, while the weighted mean difference (MD) was used as the effect size of a continuous variable. Meta-analysis was conducted with Rev Man 5.2.
RESULTSThirteen RCTs, involving 1034 patients, were included in the meta-analysis. The analysis showed that Gln enriched nutrition support was more effective in increasing serum albumin (MD: 0.10; 95% confidence interval [CI]: 0.02-0.18; P < 0.05), serum prealbumin (MD: 1.98; 95% CI: 1.40-2.55; P < 0.05) and serum transferring (MD: 0.35; 95% CI: 0.12-0.57; P < 0.05), concentration of IgG (MD: 1.26; 95% CI: 0.90-1.63; P < 0.05), IgM (MD: 0.18; 95% CI: 0.11-0.25; P < 0.05), IgA (MD: 0.22; 95% CI: 0.10-0.33; P < 0.05), CD3 + (MD: 3.71; 95% CI: 2.57-4.85; P < 0.05) and CD4/CD8 ratio (MD: 0.27; 95% CI: 0.12-0.42; P < 0.05). Meanwhile, it was more significant in decreasing the incidence of infectious complications (RR: 0.67; 95% CI: 0.50-0.90; P < 0.05) and shortening the length of hospital stay (MD: -1.72; 95% CI: -3.31--0.13; P < 0.05).
CONCLUSIONSGlutamine enriched nutrition support was superior in improving immune function, reducing the incidence of infectious complications and shortening the length of hospital stay, playing an important role in the rehabilitation of surgical GI cancer patients.

OBJECTIVETo explore the biological function of vascular endothelial cells from hypertrophic scar, and to analyze the relationship between them.
METHODSThe samples from human hypertrophic scar and normal skin tissue were harvested for histological examination. Then vascular endothelial cells were purified and isolated from the samples, and the level of transforming growth factor (TGF) beta1, platelet derived growth factor (PDGF), endothelin1 (ET)-1, fibroblast growth factor (FGF)2 and vascular endothelial growth factor (VEGF) were determined in a single cell with ELISA.
RESULTSFew capillary vessels were observed in normal skin under microscope, while an increased number of them were present in hypertrophic scar, with slender, tortuous in morphology and even occluded. The diameter of blood capillary in hypertrophic scar was tiny under electron microscope, and the exfoliation of endothelial cells was observed. The levels of TGF-beta1, PDGF, ET-1, bFGF and VEGF from vascular endothelial cells from hypertrophic scar were 60 +/- 8, 30 +/- 4, 0.12 +/- 0.03, 52 +/- 5, 18.1 +/- 1.2 microg/cell, respectively, which were obviously lower than those in normal skin (P < 0.05).
CONCLUSIONThe biological function of vascular endothelial cells was attenuated in the hypertrophic scar, which mightbe the result of the production of large amounts of collagen in the scar tissue, as well as hypoxia.

OBJECTIVETo explore the efficiency of a comprehensive surgical approach of genioglossus advancement and hyoid suspension (GAHM) plus uvulopalatopharyngoplasty (UPPP) for treating severe obstructive sleep apnea hypopnea syndrome (OSAHS) and to evaluate related factors on surgery outcomes.
METHODSEighteen patients with severe OSAHS (apnea hypopnea index, AHI > 40/h) confirmed with polysomnography received genioglossus advancement and hyoid suspension plus uvulopalatopharyngoplasty. The obstruction in both the oropharynx and the hypopharynx were evaluated by preoperative physical examination, fiberoptic pharyngolaryngoscopy, cephalometry, and computed tomography of the upper airway. The follow up was at least 6 months postoperatively. The Wilcoxon signed rank test was used to compare the preoperative and postoperative results by SPSS 11.0 for windows. The Mann-Whitney test was used to analyze the difference between responders and nonresponders.
RESULTSThe follow up time ranges from 6 to 24 months, there were statistically significance in all but body mass index (BMI) between preoperative and postoperative measurements. Mean AHI was reduced from preoperative (x +/- s, 63.8 +/- 16.3)/h to postoperative (23.6 +/- 19.5)/h, lowest mean oxygen saturation increased from 0.72 +/- 0.07 to 0.81 +/- 0.13(x +/- s). According to criterion at home, the 6-month rate of responder is 83%, if AHI <20/h and decreased by at least 50% as success, the rate of success is 67%. The age, posterior airway space (PAS) and percentage of time with oxyhemoglobin saturation below 0.90 (CT90) were (39.1 +/- 7.4) years, (8.3 +/- 0.9) mm, (18.5 +/- 10.9)% in responder, while (52.5 +/- 9.4) years, (6.8 +/- 1.3) mm, (37.7 +/- 23.6) % in nonresponder, and there are statistically significant between responder and nonresponder.
CONCLUSIONSGAHM plus UPPP is effective surgical approach for patients with severe OSAHS who suffer from oropharyngeal and hypopharyngeal obstruction. Age, PAS and CT90 were possible affective factors on surgical outcomes.

OBJECTIVETo study anatomic and computed tomographic measurements of Chinese mandibular genial tubercles and to evaluate the correlations between them.
METHODSThe axial images were taken by spiral CT in 40 adult human skulls with 1 mm thick section from infraorbital margin to menton. Sagittal plane reconstruction was produced through mandibular central line. Then the height and width of superior genial tubercles, the distance between menton and inferior margin of genial tubercles, the distance between mandibular incisor apex and superior margin of superior genial tubercles, the thickness of mandible were measured respectively. Thereafter anatomic measurements were taken by the same methods as computed tomographic images. The measured value were showed as means +/- standard deviation, then paired-t test and correlation analysis was made by SPSS 10.0.
RESULTSThe genioglossus almost origins from superior genial tubercles, geniohyoideus from inferior genial tubercles. The height of superior genial tubercles which were measured by anatomy and spiral CT were (5.82 +/- 0.71) mm and (6.17 +/- 0.71) mm respectively. The width of superior genial tubercles were (6.98 +/- 1.35) mm and (7.01 +/- 1.13) mm. The distance between menton and inferior margin of superior genial tubercles were (11.08 +/- 2.05) mm and (10.41 +/- 1.55) mm. The distance between mandibular incisor apex and superior margin of superior genial tubercles for male were (15.57 +/- 1.82) mm and (14.34 +/- 2.06)mm, and for female were (9.36 +/- 2.79) mm (8.78 +/- 2.53) mm. The thickness of mandibles at genial tubercles were (11.95 +/- 1.59) mm and (12.19 +/- 1.64) mm. The distance from menton to superior margin of superior genial tubercles were (16.1 +/- 2.30) mm and (15.73 +/- 2.12) mm. The correlations between anatomic measurements and spiral CT measurements of the above mentioned parameters were significant except for height of superior genial tubercles (r = 0.59 - 0.92).
CONCLUSIONThe anatomic and spiral CT measurements of genial tubercles appear to have significant correlations. Preoperative spiral CT measurements of genial tubercles could be help for the design of osteotomy in genioglossus advancement.
