OBJECTIVETo observe the therapeutic effect of Yangxue Qingnao granule (YXQNG) in treating chronic cerebrovascular insufficiency (CCI) and its possible mechanism.
METHODSEighty-three patients with CCI were randomly divided into YXQNG and nimodipine (ND) groups, the score of vertigo and the change in cerebral blood velocity before and after treatment were observed. And in the animal experiment, the authors adopted bilateral ligation of cervical carotid communis artery to establish CCI rat models in order to observe the effect of YXQNG and ND on incubation period of vertigo in rats and on memory performance.
RESULTSAfter clinical treatment, the vertigo score of YXQNG group was 2.34, and that of the ND group was 4.18, the comparison between the two groups showed that the difference was significant (P < 0.05). After treatment, the middle cerebral artery mean velocity (MCA Vm) of YXQNG group was 64.78 cm/s, vertebral artery mean velocity (VA Vm) was 29.78 cm/s, while that of ND group was 60.34 cm/s and 23.23 cm/s respectively, the comparison between these two groups showing statistical significance and the difference being obvious (P < 0.05). Experimental study showed that the rats in the model group after 12 weeks learning and memory were markedly lowered, the vertigo incubation period significantly lengthened, and compared with that of the model group, learning and memory of the YXQNG group was markedly improved and vertigo incubation period shortened, with the difference from that of the ND group insignificant, P > 0.05.
CONCLUSIONYXQNG could effectively improve CCI patients' vertigo and other clinical symptoms and increase the cerebral blood flow, lessen the vertigo incubation of model group rats, elevate model group rats' memory performance.

OBJECTIVETo develop a standard Neglect Evaluation Scale which is suitable for rural primary school students in China.
METHODSAccording to the principle of multi-stage stratified cluster sampling, a field investigation was conducted among primary school students in 28 counties from 7 provinces and 2 municipalities. The questionnaires were self-designed, and determined by multiple rounds of pilots and revisions. Among 5 862 students, 2 792 (6-8 years' old) and 3 070 (9-11 years' old) were investigated by using two kinds of Neglect Evaluation questionnaires, respectively. After project analysis, factor analysis, reliability and validity analysis, the reliability and stability of the scale were tested. Then percentile method was used to determine the evaluation standard to develop and finalize the formal scale.
RESULTSThe numbers of the remaining items for 6-8 year-old group and 9-11 year-old group is 69 and 58, respectively, both of which contain six levels of neglect, including body, emotion, health care, education, security, and society. 4 times of factor analysis were conducted in both of the two groups. The factor loadings in these two groups were 0.290-0.700 and 0.276-0.729 respectively. Reliability test results showed that the two kinds of scales' Cronbach alpha coefficient were 0.924 and 0.929 respectively, split-half reliability were 0.891 and 0.904 respectively, the retest reliability were 0.559 and 0.892 respectively, the differences were statistically significant (P < 0.05). The retest reliability among 6-8 year-old group in medical neglect level had no statistical significance, but was close to the cut-off point (P = 0.054). The test results of external validity indicated that both of the two scales could reflect the neglect status of the subjects (P < 0.05), but the subjective and objective evaluation towards neglect were not consistent. The cut-off points for judging whether the children were neglected or not among 6-8 year-old and 9-11 year-old groups were 159 and 137 respectively; and the adjusted values were 160 and 135 respectively.
CONCLUSIONThe two norm scales developed by this study showed good discriminability, reliability, validity, and stability. The norms developed on the basis of the scales was suitable for the situation of rural students in primary schools in China.

ObjectiveTo optimize the existing genetic transformation system of Armillaria gallica to improve the transformation efficiency and lay a foundation for the follow-up research on Armillaria molecular marker-assisted breeding and gene function. MethodThe genetically transformed plasmid pH101-PAgGPD-GFP-TrpC was constructed,transformed into Escherichia coli,amplified, and cultured,and the plasmid was extracted. The extracted plasmid was transformed into four different agrobacteria LBA4404,EHA105,GV3101,and AGL-1,respectively. The transformed agrobacteria were used for impregnating A. gallica,and the agrobacteria with the highest conversion rate were screened out. Then the agrobacterium-mediated genetic transformation system of A. gallica was optimized from the type and concentration of antibiotics,co-culture time,concentration of bacterial solution, and impregnation method. The phenotype profiles of A. gallica under different conditions were observed using Synbiosis ProtoCol 3. ResultThe optimized genetic transformation conditions of A. gallica were as follows: the Agrobacterium strain of EHA105 at absorbance A600 nm=0.6, the co-culture time of 2 d, the infection mode of negative pressure impregnation for 10 min, the primary screening medium of PDA medium containing 400 mg·L-1 cefotaxime sodium and 10 mg·L-1 hygromycin,and the secondary screening medium of PDA medium containing 12 mg·L-1 hygromycin. ConclusionIn this study,the existing genetic transformation system of A. gallica was optimized,and there was a significant difference in the transformation rate before and after optimization (P<0.05). After optimization,the transformation efficiency of A. gallica was about 4.33%,which was about eight times higher than that before optimization.

Objective: To study the effects of superficial temporal artery and vein as recipient vessels for the free anterolateral thigh flap on the appearance and functions after maxillectomy. Methods: Clinical data of 21 patients with malignant maxillary tumors in Department of Oral and Maxillofacial Surgery, the Second Xiangya Hospital of Central South University from January 2014 to November 2019, who were treated by free anterolateral thigh flap with temporal superficial vessels as the recipient vessels were analyzed retrospectively. There were 18 males and 3 females, with the age ranging from 29 to 73 years old, including 19 cases of squamous carcinoma, 1 case of adenoid cystic carcinoma and 1 case of osteosarcoma. Of those 7 patients underwent primary surgery, 14 patients received resurgery, and 6 patients had a history of postoperative radiotherapy and chemotherapy. Among 14 patients with resurgery, 13 had recurrent ipsilateral second site tumor and 1 had recurrent tumor, and all of them received the maxillectomy and reconstructive surgery with the free anterolateral thigh flap. Patients were evaluated with water swallow test and speech intelligibility score in 1, 3 and 6 months after operation. The data were statistically analyzed with SPSS 22.0 statistical software. Water swallow test results before and after operation were compared using the Wilcoxon rank sum test. The mean speech intelligibility scores before and after operation were compared by the paired t test. Results: Patients were followed up for 10-60 months. All free flaps survived after operation. No diplopia occurred. Breathing, swallowing and speaking functions were normal. No movement disorders caused by the donor of thigh flap. Water swallow test showed no phenomenon of water flowing into the nasal cavity or oral and nasal leakage with level Ⅰ for 4 cases, level Ⅱ for 13 cases, level Ⅲ for 3 cases and level Ⅳ for 1 case. The mean speech intelligibility scores before surgery and 1, 3 and 6 months after surgery were 4.31±0.13, 1.46±0.21, 2.15±0.45 and 2.87±0.76 respectively. There was statistically significant difference in the mean speech intelligibility scores between 1 and 6 months after surgery (F=78.456, P<0.05). Conclusion: It is safe and reliable to use the superficial temporal vessels as recipient vessels for free anterolateral thigh flap in the reconstruction of defect after maxillectomy in malignant tumors, with good outcomes of functions and a satisfactory restoration of outward appearance.

Objective:
To investigate the effects and molecular mechanisms of mechano-growth factor (MGF) on the proliferation and differentiation of periodontal ligament stem cells (PDLSCs).
Methods:
PDLSCs were obtained using magnetic bead sorting. Flow cytometry was performed to identify biomarkers. The clonogenicity and multidifferentiation potential of PDLSCs were identified by colony-forming unit, osteogenic and adipogenic differentiation assays. A CCK8 assay was used to detect the cell activity under different concentrations of mechano-growth factors (MGF-Ct24E). Western blot was used to detect the protein expression of proliferating cell nuclear antigen(PCNA), Scleraxis, collagen type I alpha 1 (COL1A1), Osterix, Yes-associated protein (YAP) and phosphorylation Yes-associated protein (P-YAP)in PDLSCs. YAP protein expression was observed by immunofluorescence. Knockdown of YAP expression by a siRNA, detected the expression of PCNA, Scleraxis and COL1A1under MGF-Ct24E in PDLSCs.
Results :
PDLSCs showed high expression of stem cell markers (CD29, CD90 and CD105) and low expression of hematopoietic markers (CD34 and CD45). PDLSCs also have a strong ability to clone. Red calcium junctions were observed by Alizarin red staining, and red lipid droplets were observed by Oil red O staining. After treatment with 50 ng/mL and 100 ng/mL MGF-Ct24E for 24 h, the cell activity of periodontal ligament stem cells was significantly enhanced (P<0.05). The protein expression of PCNA, Scleraxis and COL1A1 was significantly upregulated, and the protein expression of Osterix was significantly downregulated (P<0.05). After treatment with 50 ng/mL mechano-growth factor for 24 h, the phosphorylation of YAP protein was significantly enhanced (P<0.05), and YAP protein was observed to accumulate in the nucleus by immunofluorescence. Following inhibition of YAP expression, PCNA and Scleraxis had significantly downregulated expression caused by MGF-Ct24E (P<0.05).
Conclusion
MGF promotes proliferation and fibrogenesis via upregulation of YAP activities.

Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

Bungarus Parvus, a precious animal Chinese medicinal material used in clinical practice, is believed to be first recorded in Ying Pian Xin Can published in 1936. This study was carried out to analyze the names, geographical distribution, morphological characteristics, ecological habits, poisonousness, and medicinal parts by consulting ancient Chinese medical books and local chronicles, Chinese Pharmacopeia, different processing standards of trditional Chinese medicine(TCM) decoction pieces, and modern literatures. The results showed that the earliest medicinal record of Bungarus Parvus was traced to 1894. In 1930, this medicinal material was used in the formulation of Annao Pills. The original animal, Bungarus multicinctus, was recorded by the name of "Bojijia" in 1521. The morphological characteristics, ecological habits, and poisonousness of the original animal are the same in ancient and modern records. The geographical distribution is similar between the ancient records and modern documents such as China Medicinal Animal Fauna. The dried body of young B. multicinctus is used as Bungarus Parvus, which lack detailed references. As a matter of fact, it is still inconclusive whether there are differences between young snakes and adult snakes in terms of active ingredients, pharmacological effects, and clinical applications. This study clarified the medicinal history and present situation of Bungarus Parvus. On the basis of the results, it is suggested that systematic comparison on young and adult B. multicinctus should be carried out to provide references for revising the medicinal parts of B. multicinctus.
