Journal of Acupuncture and Tuina Science 2022;20(2):152-158
Objective: To observe the clinical efficacy of warm needling moxibustion plus Tuina (Chinese therapeutic massage) for knee osteoarthritis (KOA).Methods: A total of 60 patients with KOA were randomized into an observation group and a control group by the random number table, with 30 cases in each group. The control group was treated with warm needling moxibustion, and the observation group was treated with additional Tuina treatment. The treatments were performed once every other day, for a total of 10 times. The visual analog scale (VAS) and Western Ontario and McMaster Universities osteoarthritis index (WOMAC) were scored before and after treatment, and the surface electromyography (sEMG) signals of quadriceps femoris were collected. Results: The total effective rate of the control group was 76.7%, and that of the observation group was 90.0%. The difference between the two groups was statistically significant (P<0.05). The WOMAC and VAS scores in both groups after treatment were improved, and the integrated electromyography (iEMG) and median frequency (MF) of quadriceps femoris were increased. The intra-group differences were statistically significant (P<0.05). After treatment, the WOMAC and VAS scores in the observation group were lower than those in the control group, and the differences between the two groups were statistically significant (P<0.05). The improvement of quadriceps femoris function in the observation group was more notable than that in the control group, and the iEMG value and MF were significantly higher than those in the control group (P<0.05). Conclusion: Warming needling moxibustion plus Tuina can effectively relieve the pain in patients with KOA, improve their daily activity function, and increase the sEMG signals of the quadriceps femoris.

Objective To evaluate the anti-human respiratory syncytial viurs ( hRSV ) effect of aminoglucomannan ( AGM) in mice.Methods BALB/c mice infected with hRSV were randomly divided into AGM and konjac glucomannan ( KGM) groups with 54 in each.Then, mice in AGM group and KGM group were subdivided into three groups and treated with different doses of AGM or KGM as 2.5 μmol/L, 0.25 μmol/L or 0.025μmol/L.Each subgroup was further divided into 3 groups with 6 in each according to administration intervals of AGM or KGM as 8 h, 12 h or 24 h.All the mice are sacrificed at 72 h.The general condition of the mice was observed everyday.Reverse transcription-polymerase chain reaction ( RT-PCR) was used to detect the expression of hRSV fusion protein ( F) mRNA in the lung tissue of the mice. HE staining method and immunohistochemistry technique for intercellular cell adhesion molecule-1 ( ICAM-1) expression in the lung tissue were used to evaluate the inflammation in the lung tissue.ANOVA for randomized block design was used to examine the influence of dose and administration intervals on the expressions of hRSV F mRNA and ICAM-1.Results Reduced activity and asthma were observed in 16 mice in the KGM group, but not in the AGM group.And two mice in the KGM group died at d3, but there was no death in the AGM group.RT-PCR showed that the levels of hRSV F mRNA in lung tissues were 0.49 ±0.21 in AGM group and 0.88 ±0.06 in KGM group (t=6.71, P<0.05).HE staining of lung tissue showed that the inflammation in KGM group was more serious than that in AGM group.The expression of ICAM-1 in AGM group was much lower than that in KGM group, and there was statistical difference between two groups (t=13.88, P<0.05).In AGM group, the levels of RSV F mRNA and ICAM-1 decreased with the increase of AGM’s concentration and rised with longer administration intervals (P<0.05), but these were not observed in KGM group (P>0.05).Conclusion AGM can alleviate the inflammation of lung tissue in mice infected with hRSV in a dose and time-depandent manner.

Objective The aim of this study was to investigate the clinical value of human serum Kallikrein 6 for the diagnosis and monitor of pithelial ovarian cancer. Methods Serum levels of KLK6 were analyzed with ELISA in 30 cases of epithelial ovarian carcinoma, 20 cases of benign ovarian tumor and 30 cases of healthy women. In the meantime, serum CAi25 was determined with chemiluminescence. Furthermore, serum levels of KLK6 and CA125 were also detected in 12 case of epithelial ovarian carcinoma with the same methods one week and the 3rd month postoperation of follow-up. Results Serum levels of KLK6 in epithelial ovarian carcinoma was higher than that in benign ovarian tumor and healthy women (P < 0.05). KLK6 also showed positive correlation with clinical stage, cytological grade, pelvic lymph node metastasis, recurrent or dead disease (P < 0. 05). On the contrary, KLK6 showed no significant correlation with pathological types (P >0. 05). After surgery of follow-up, KLK6 and CA125 were significantly decreased in 12 case of epithelial ovarian carcinoma (P < 0. 05). Furthermore, the total sensitivity and specificity of KLK6 in the diagnosis of epithelial ovarian carcinoma was 73.3% and 85.0% respectively, followed by the sensitivity to be 50. 0% and 88. 9% for the diagnosis of stage Ⅰ-Ⅱand Ⅲ-Ⅳ disease. Conclusion Our resuits showed KLK6 may be one of the reliable indexes for the diagnosis and monitor of ovarian cancer.

OBJECTIVE:
To explore the genetic basis for a child with optic atrophy and global developmental delay.
METHODS:
A child who had presented at the Guangzhou Women and Children's Medical Center in January 2022 was selected as the study subject. Clinical data were collected. Whole exome sequencing (WES) was carried out for the child. Candidate variant was validated by Sanger sequencing and bioinformatic analysis.
RESULTS:
The child, a nine-month-old female, had manifested dysopia and global developmental delay. Genetic testing revealed that she has harbored a de novo c.425G>C (p.Arg142Pro) variant of the NR2F1 gene, which has been associated with Bosch-Boonstra-Schaaf syndrome. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as pathogenic (PS2+PM1+PM2_Supporting+PM5+PP3+PP4).
CONCLUSION
The c.425G>C (p.Arg142Pro) variant of the NR2F1 gene probably underlay the pathogenesis in this child. Above finding has enriched the genotypic and phenotypic spectrum of the NR2F1 gene.

Objective To explore the capability of leukocytosis in predicting the survival time of patients with advanced malignant tumors,in order to provide evidences for clinicians to make the best therapy regimen. Methods The clinical data of 103 dead patients with advanced malignant tumors treated from September 2015 to September 2016 were collected.The relationship between peripheral blood white blood cell count (WBC) and survival time of patients was analyzed retrospectively. The survival analysis was performed by Kaplan-Meier and Log-rank test,and Cox regression was used for multivariate analysis. Results An elevated peripheral blood WBC was found in 61.1%(63/103) dead patients with advanced malignant tumors, and the elevated WBC was negatively correlated with the life span (r=-0.569, P=0.000). Conclusion Elevated WBC in some advanced malignancy patients predicts they are in the end-stage, which can guide clinicians adjust treatment regimens in time,and they may consider palliative care for those patients.

M2 protein of influenza A virus is encoded by a spliced mRNA derived from RNA segment 7 and plays an important role in influenza virus replication. It is also a target molecule of anti-virus drugs. We extracted the viral genome RNAs from MDCK cells infected with swine influenza A virus (SIV) H3N2 subtype and amplified the SIV M2 gene by reverse transcriptase-polymerase chain reaction using the isloated viral genome RNAs as template. The amplified cDNA was cloned into a prokaryotic expression vector pET-28a(+) (designated pET-28a(+)-M2) and a eukaryotic expression vector p3xFLAG-CMV-7.1 (designated p3xFLAG-CMV-7.1-M2), respectively. The resulted constructs were confirmed by restriction enzyme digestion and DNA sequencing analysis. We then transformed the plasmid pET-28a(+)-M2 into Escherichia coli BL21 (DE3) strain and expressed it by adding 1 mmol/L of IPTG (isopropyl-beta-D-thiogalactopyranoside). The recombinant M2 protein was purified from the induced bacterial cells using Ni(2+) affinity chromatography. Wistar rats were immunized with the purified M2 protein for producing polyclonal antibodies specific for it. Western blotting analysis and immunofluorescence analysis showed that the produced antibodies were capable of reacting with M2 protein expressed in p3xFLAG-CMV-7.1-M2-transfected cells as well as that synthesized in SIV-infected cells. We also transfected plasmid p3xFLAG-CMV-7.1-M2 into Vero cells and analyzed its subcellular localization by immunofluorescence. The M2 protein expressed in the Vero cells was 20 kDa in size and dominantly localized in the cytoplasm, showing a similar distribution to that in SIV-infected cells. Western blotting analysis of SIV-infected cells suggested that M2 was a late phase protein, which was detectable 12 h post-infection, later than NS1, NP and M1 proteins. It would be a potential molecular indicator of late phases replication of virus. Our results would be useful for studying the biological function of M2 protein in SIV replication.
