Abstract: Objective To analyze and compare the effects of different clinical characteristics on the negative conversion time of nucleic acid detection after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infection, and to provide a scientific basis for the isolation and treatment of coronavirus disease 2019 (COVID-19). Methods　The epidemiological and clinical data of 228 mild SARS-CoV-2 Omicron variant infected patients diagnosed in Shanghai were retrospectively collected from April 27, 2022 to June 8, 2022 in Wujiaochang designated Hospital, Yangpu District, Shanghai. The negative conversion time of nucleic acid detection was used as the outcome variable, and the patients were divided into A (≤18 days) and B (>18 days). Univariate and multivariate logistic regression analysis were used to analyze the influencing factors of the negative conversion time of nucleic acid detection. Results　The mean nucleic acid conversion time of 228 patients was (18.7±12.1) d, with the median time of 18 (2-46) d. Among them, 120 patients in group A had an average nucleic acid conversion time of (13.2±2.0) d, and 108 cases in group B had an average nucleic acid conversion time of (20.8±1.3) d. Univariate analysis showed that there were no statistically significant differences in the effects of hypertension, coronary heart disease, diabetes, hypokalemia, malignant tumors, neuropsychiatric diseases, chronic digestive diseases on the negative nucleic acid conversion time (P>0.05); however, there were significant differences in the effects of combined cerebrovascular disease, leukopenia, chronic respiratory system diseases and vaccination on the negative nucleic acid conversion time (P<0.05). Further multivariate logistic regression analysis revealed that the combination of chronic respiratory diseases and non-vaccination were significant risk factors for prolongation of negative nucleic acid conversion time (P<0.05). Conclusions The results of this study show that gender, age and whether hypertension, coronary heart disease, diabetes mellitus, hypokalemia, malignant tumor, neuropsychiatric disease and chronic digestive disease have no significant effect on the nucleic acid conversion time, whereas chronic respiratory disease and no vaccination are significantly correlated with the prolongation of nucleic acid conversion time in SARS-CoV-2 Omicron-infected patients.

Objective To study the clinical manifestations, radiological features, andpostoperative outcomes of patients with subependymal giant cell astrocytoma (SEGA). Methods Aretrospective analysis of the clinical presentations, imaging examinations, pathological features,treatments and follow-up results was conducted in 6 SEGA cases treated in our department from 2000 to2007. Results The most common clinical maifestations of SEGA included increased intracranialpressure and impaired visual acuity. CT scan of the tumors displayed isodensity or slightly increaseddensity with well defined border. Calcification was seen in some of the tumors. On T1-weighted magneticresonance images, the tumor masses presented with isointense or mixed signals, while on T2-weightedimages, the tumors exhibited isointense or hyperintense signals. The solid part of the tumor showedheterogeneous enhancement in contrast-enhanced imaging. No operative death occurred in these casesafter total removal of the tumors through a transcallosal approach (4 cases) or a frontal transcorticalapproach (2 cases). No postoperative tumor recurrence was found in the follow-up for 10 months to 8years. Conclusion The diagnosis of SGCA should be considered for the presence of tuberous sclerosisin the subependymal lesion adjacent to the foramen of Monro in cases presenting hydrocephalus orprogressive tumor growth. Surgical resection of the tumor should be performed as early as possible.SGCA is a benign tumor with good prognosis after a total resection. Regular follow-up examinationshould be undertaken to monitor the subependymal nodules for prevention of tumor recurrence.

OBJECTIVETo evaluate the efficacy and safety of Capsule metadoxine in the treatment of alcoholic liver disease.

METHODSA randomized double blind multicenter placebo-controlled clinical study was performed to evaluate the therapeutic effectiveness and safety of capsule metadoxine. Patients in metadoxine group received capsule metadoxine 500mg tid po. Patients in placebo group received placebo 2 pillows tid po. The treatment duration was 6 weeks. Patients were followed up 2 weeks after the treatment. Patients were visited once every 3 weeks during the treatment period. Clinical symptoms and liver function were evaluated in all the patients before treatment, at week 3, week 6 and 2 weeks after therapy. CT scan was done in some patients before treatment and at the end point of therapy.

RESULTS254 patients were recruited in the study, 126 in metadoxine group and 128 in placebo group. Median ALT, AST, GGT level in metadoxine group were decreased from 80.0 U/L, 59.2 U/L, 123.0 U/L (before treatment) to 41.1 U/L, 36.0 U/L, 57.0 U/L (after 6 weeks therapy). The improvement in liver function was more significant in metadoxine group than in placebo group (P less than 0.05). For the patients who stopped drinking during the study, the total effective rate of improvement in liver function was 82.8% in metadoxine group, much higher than that in placebo group (55.7% , P=0.0000). For the patients who did not stop drinking during the study, the total effective rate of improvement in liver function was 65.4% in metadoxine group, which is not significantly higher than that in placebo group (44.8%, P=0.1767). The CT value ratio of liver to spleen was significantly improved in metadoxine group (P=0.0023), and there was no significant difference between the two groups (P=0.6293). The rate of adverse was 1.6% in both of groups.

CONCLUSIONCapsule metadoxine is an effective and safe treatment for alcoholic liver disease.

OBJECTIVETo explore the effect of myringotomy with insertion of tube and tympanocentesis on alleviating secretory otitis media (SOM) and hearing loss in cleft palate infants.

METHODSNineteen cleft lip and palate infants with SOM and hearing loss (38 ears) were treated with myringotomy with insertion of ventilation tube at the same time of repair of the cleft lip, who were performed averagely at 6.9 months of age. Fifteen cleft lip and palate infants with SOM (30 ears) were treated with tympanocentesis at the same time of repair of the cleft lip averagely at 6.6 months of age. All cases were followed up from 1 week to 12 months and estimated by auditory brainstem response (ABR) and acoustic immitance audiometry.

RESULTSThe average wave V reacting thresholds of ABR were separately 55.41 dBnHL and 28.48 dBnHL, and 79.17% tympanogram B changed to tympanogram A in cleft palate infants with insertion of tube before and after operation. The average wave V reacting thresholds of ABR were separately 40.63 dBnHL and 26.50 dBnHL, and 40.91% tympanogram B changed to tympanogram A in cleft palate infants with tympanocentesis preoperatively and in 1 week postoperatively, in whom the average hearing thresholds and tympanograms had no significant difference preoperatively and in 1 or 3 months postoperatively (P>0.05).

CONCLUSIONThe early myringotomy with insertion of tube is effective to restore the function of the middle ear in cleft palate infants with SOM, so to suggest to be performed at the same time of the repair of cleft lip within the first 1-year of life. The tympanocentesis should not be used as a regular management in the cleft palate infants with SOM.

OBJECTIVETo study the expression changes of neuroglobin in rats with the model of diffuse traumatic brain injury and explore the relationship between the neuroglobin and neuron apoptosis in traumatic brain injury.

METHODSThe diffuse traumatic brain injury of rats was induced by the Marmarou's 'weight-drop' device. And the immunohistochemical technique was used to detect the expression changes of neuroglobin and neuron apoptosis in rat brain at different time points post-injury.

RESULTSThe expression of neuroglobin increased twice and reached peaks at 2 hours and 72 hours post-injury respectively. And the increased expression of neuroglobin from 30 minutes to 1 hour post-injury and from 48 hours to 72 hours post-injury accompanied with the decreased expression ratio of Bax to Bcl-2.

CONCLUSIONThe increased expression of neuroglobin in traumatic brain injury informed us that neuroglobin had anti-apoptosis action in post-injury neuron. It could protect the neuron from traumatic stress and secondary ischemia and hypoxia insults during ultra-early and acute stages.

OBJECTIVETo investigate the constituent expression of PH domain leucine-rich repeat protein phosphatase 1 (PHLPP1) in human umbilical vein endothelial cells (HUVECs) and the effect of PHLPP1 gene transfer on the proliferation of the cells in vitro.

METHODSCultured HUVECs were transfected with pcDNA3-GFP or pcDNA3HA-PHLPP1 via lipofectamine 2000. The cell proliferation ability was determined by cell counting and MTT colorimetric assay, and Western blotting was used to detect the protein expression of PHLPP1 in the cells.

RESULTSNo PHLPP1 protein was detected in the non-transfected cells or pcDNA3-GFP-transfected cells. pcDNA3HA-PHLPP1 gene transfection significantly increased PHLPP1 expression in the HUVECs (P<0.01), but the cell proliferation status remained unchanged (P>0.05). The absorbance of the cells measured by MTT assay was 0.134-/+0.0152, 0133-/+0.014 and 0.137-/+0.016, with cell counts of (8.293-/+0.962)x10(5), (7.937-/+0.101)x10(5) and (8.127-/+0.112)x10(5), respectively, showing no significant differences between the 3 groups (P>0.05).

CONCLUSIONSPhosphatase PHLPP1 may not be the most important signal protein in the regulation of HUVEC proliferation.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.

Steaming method is a traditional processing method for Gastrodiae Rhizoma(GR). The current studies on the steaming method's mechanism of GR are mainly focused on facilitating softening slice, destroying the β-glycosidic bond enzymes to reduce the decomposition of gastrodia glycosides (killing enzyme and protecting glycosides). The researches on the processing mechanism are still incomplete, while revealing and analyzing the active components in the body's metabolic process are important channels and new models to clarify the mechanism of traditional medicine processing. In order to provides a reference for the in-depth study of the processing mechanism of GR, we have reviewed the relevant literature at home and abroad in recent years and briefly summarized the processing, composition analysis and in vivo metabolism of GR in this study.
