Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Objective: To explore the clinical and imaging features of acute encephalopathy with biphasic seizures and late reduced diffusion(AESD) in children. Methods: For the case series study, 21 children with AESD from Peking University First Hospital, Provincial Children's Hospital Affiliated to Anhui Medical University, Children's Hospital of Fudan University, and Shanxi Children's Hospital who were diagnosed and treated from October 2021 to July 2023 were selected. Clinical data were collected to summarize their clinical information, imaging, and laboratory tests, as well as treatment and prognostic characteristics. Descriptive statistical analysis was applicated. Results: Of the 21 cases with AESD, 11 were males and 10 were females, with the age of onset of 2 years and 6 months (1 year and 7 months, 3 years and 6 months). Of the 21 cases, 18 were typical cases with biphasic seizures. All typical cases had early seizures within 24 hours before or after fever onset. Among them, 16 cases had generalized seizures, 2 cases had focal seizures, and 7 cases reached the status epilepticus. Of the 21 cases, 3 atypical cases had late seizures in biphasic only. The late seizures in the 21 cases occurred on days 3 to 9. The types of late seizures included focal seizures in 12 cases, generalized seizures in 6 cases, and both focal and generalized seizures in 3 cases. Diffusion-weighted imaging (DWI) test on days 3 to 11 showed reduced diffusion of subcortical white matter which was named "bright tree sign" in all cases. The diffuse cerebral atrophy predominantly presented in the front-parietal-temporal lobes was found in 19 cases between day 12 and 3 months after the onset of the disease. Among 21 cases, 20 had been misdiagnosed as autoimmune encephalitis, central nervous system infection, febrile convulsions, posterior reversible encephalopathy syndrome, acute disseminated encephalomyelitis, and hemiconvulsion-hemiplegia-epilepsy syndrome. All the cases received high-dose gammaglobulin and methylprednisolone pulse therapy with poor therapeutic effect. By July 2023, 18 cases were under follow-up. Among them, 17 cases were left with varying degrees of neurologic sequelae, including 11 cases with post-encephalopathic epilepsy; 1 recovered completely. Conclusions: AESD is characterized by biphasic seizures clinically and "bright tree sign" on DWI images. Symptomatic and supportive treatments are recommended. The immunotherapy is ineffective. The prognosis of AESD is poor, with a high incidence of neurological sequelae and a low mortality.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

OBJECTIVE: To investigate the effects of different routes in placental mesenchymal stem cells (PMSC) on serum expression levels of IL-4, IL-17, TNF-α and IFN-γ in aplastic anemia (AA) rats. METHODS: The rat model of aplastic anemia (AA rats) was established by 5-fluorouracil combined with busulfan. The rats was divided into four groups: control, experimental, PMSC-injected into the tail vein, and PMSC-injected into the medullary cavity. The general state of rats in each group was observed in detail before and after treatment. The serum levels of interleukin-4 (IL-4) , interleukin-17 (IL-17), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ) were measured by enzyme-linked immunosorbent assay (ELISA) at week 1, 3 and 5 after treatment. RESULTS: The serum levels of TNF-α, IFN-γ and IL-17 in the experimental group were significantly higher than those in the control group, while the level of IL-4 was significantly decreased (P＜0.05). The levels of TNF-α, IFN-γ and IL-17 gradually decreased after treatment while the level of IL-4 increased. By the fifth week, the above indexes were closed to the control group (P＞0.05), and the levels of TNF-α, IFN-γ and IL-17 in the group with PMSCs injected via the medullary cavity decrease more significantly than those group with PMSC injected via the tail vein, but level of IL-4 was not significantly different between two groups. CONCLUSION The level of serum hematopoietic negative regulators increase significantly, and the level of hematopoietic promoting factors decreases significantly in aplastic anemia rats. PMSC can down-regulate the level of hematopoietic negative regulators and up-regulate the level of hematopoietic promoting factors in the rats with aplastic anemia, and the inhibition of hematopoietic negative regulators by intramedullary injection is more significant than that by caudal vein injection.

Objective:To analyze the status quo and development of the Hope Houses for individuals with spinal cord injury (SCI) in Shanghai. Methods:In June, 2018, the organizers and managers of Hope Houses from 16 districts in Shanghai were investigated with the self-designed questionnaires, which covered the personal characteristics, knowledge of related policy, development of projects and obstacles, and rehabilitation recognition. The descriptive analysis and correlational analyses were conducted. Results:Totally, eleven organizers and 16 managers were investigated. The knowledge of related policy for organizers was not good enough. Eight Hope Houses in 16 districts in Shanghai were operated by social organizations. The average implementation rate of projects in Hope Houses was 60.6%, and the highest was rehabilitation knowledge education (96.3%). There was insufficient provision in legal services, job skills training, rehabilitation nursing guidance, job referral, medical referral and education referral, etc. The main related factors limiting the development of the Hope Houses were lacks of budgets, social consensus and professionals. The rehabilitation cognition of organizers and managers was generally good, but the cognition of rehabilitation principles and rehabilitation value needed to be strengthened. Conclusion:The Hope Houses for individuals with SCI in Shanghai work well, and the rehabilitation cognition of organizers and managers is satisfactory. It should be strenghened in resource input, comprehensive rehabilitation and standard of management, to expand the service timely.

OBJECTIVE To study the methodology of achieving stable co-expression of drug-metab?olizing enzymes in the HepG2 cells by the piggyBac (PB) transposon system. METHODS N-terminal attachment of enhanced green fluorscent protein plasmid (pEGFP- N2) and 2A peptide linked recombinant PB transposon plasmid containing dual-genes encoding drug metabolizing enzymes cyto?chrome P450 3A4 (CYP3A4) and CYP2C19 (pPB-CYP3A4-2A-2C19) were transfected into HepG2 cells respectively by Lipofectamine?LTX reagent, GenJetTM (Ver.Ⅱ) reagent and Neon?Transfection System reagent, which were widely used for large-sized DNA fragments transfection. 48 h later, the transfection efficiency and cell toxicity were detected and compared between the three methods so as to find a method with relatively high efficiency and low toxicity for later transfection.Then,three groups of recombinant PB transposons-single-gene transposon (PB-CYP3A4), 2A peptide linked dual-gene transposon (PB-CYP3A4-2A-2C19) and multiple single-gene transposon mixture〔PB-CYP3A4, PB-CYP2C8, PB-CYP2A6, organic anion transporting polypeptide 1B1 PB transposon (PB-OATP1B1)〕-were transfected into HepG2 cells respectively with the above established method.The puromycin (Puro)-resistant and GFP positive cell clones were picked up and further cultured. The mRNA, protein and metabolic levels of drug-metabolizing enzymes in monoclonal cell lines were detected by quantitative real-time PCR,Western blotting and high performance liquid chromatography-tandem mass spectrometry respectively after screening by Puro and green fluorescence. Comparisons of different groups were made using statistical analysis. RESULTS The comparison of three different transfection methods indi?cated that the transfection efficiency of GenJetTMwas up to(94.2±2.5)% and (89.3±3.3)%,significantly higher than those of the other two methods (P<0.01), along with lower cytotoxicity. Then GenJetTMwas chosen for later transfection. In the Puro-resistant monoclonal cell lines of single transposon PB-CYP3A4,PB-CYP3A4-2A-2C19 groups,the mRNA,protein and enzyme activity levels of drug-metabo?lizing enzymes were significantly increased respectively.The recombinant transposon (PB-CYP3A4-2A-2C19) containing 2A peptide could achieve stable and efficient co-expression of two metabolizing enzymes CYP3A4 and CYP2C19,while the expression of drug-metabolizing enzymes remained unbal?anced and random in those of multiple single-gene transposon mixture group (PB-CYP3A4, PB-CYP2C8,PB-CYP2A6,PB-OATP 1B1)(CYP3A4 was expressed in some cell clones only).CONCLUSION GenJetTM could be an effective method for the PB recombinant transposon transfection into HepG2 cells, by which the PB transposon could mediate stable expression of drug-metabolizing enzymes. In terms of multi-gene expression,a low and unbalanced expression is found by multiple transposons co-transfection method,which is different from that by virus mediated method.In contrast,mono-PB trans?poson linked by 2A peptide can achieve stable expression of multi-genes.

ObjectiveTo compare the clinical efficiency of Shang Ring with that of the disposable circumcision suture device (DCSD) in the treatment of phimosis or redundant prepuce.

METHODSFrom June 2013 to March 2015, we treated 320 patients with phimosis or redundant prepuce using Shang Ring (n=158) or DCSD (n=162). We compared the operation time, intra-operative blood loss, incision healing time, postoperative complications, postoperative satisfaction, and treatment cost between the two groups of patients.

RESULTSComparison between the Shang Ring and DCSD groups showed that the operation time was (5.6±1.3) vs (5.4±1.2) min, intra-operative blood loss (1.2±0.8) vs (1.3±0.9) ml, postoperative delayed hemorrhage 3.16% (5/158) vs 4.32% (7/162), incision healing time (16.1±7.2) vs (7.5±2.3) d, wound infection 15.82% (25/158) vs 7.41% (12/162), 1-month postoperative incision edema 29.11% (46/158) vs 9.26% (15/162), overall postoperative satisfaction rate 63.92% (101/158) vs 90.12% (146/162), and treatment cost (1121.2±15.6) vs (2142.6±10.8) RMB ¥. There were statistically significant differences between the two groups in the latter five parameters (P<0.05 ), but not in the first three (P>0.05 ).

CONCLUSIONSThe DSCD has an obvious superiority over Shang Ring for its relatively lower complication rate, shorter incision healing time, and better cosmetic appearance.

Objective To investigate the A (H1N1 ) influenza patients whose viral expulsion law and antiviral effecacy in Shenzhen city in 2009. Methods A (H1N1) flu virus nucleic acid positive by reverse transcription-polymerasechain reaction (RT-PCR) with nose swabs pharynx swabs two times were showed in 75 patients. Thereafter, to detect the virus nucleic acid once per day until negative for two days in a row. Begin the antiviral therapy with Oseltamivir (Ⅰ) or the Chinese medicine (Ⅱ) or Oseltamivir combined the Chinese medicine (Ⅲ) respectively for 5 days immediately after testing virus positive at the first time. T lymphocyte subpopulation and IL-17 were identified by flow cytometry. Results 78.7% ( 59/75) of patients whose mean age was (22.25±10.38) years old virus nucleic acid turned negative in 7 days of duration. 21.3% (16/75) of patients whose mean age was (17.16±13.66) years old virus were still positive after 7 days of duration. Analysis of humoral and cellular immune function in 56 patients with A (H1N1) flushowed down IL-17 expression compared with seasonal flu and health control(P ＜ 0.01 ). 10cases virus persistence more than 7 days showed down IL-17 expression( 1.91 ± 0. 80)compared with that of 46 cases virus persistence smaller or equal to 7 days ( 3.05±1.59 ) ( P ＜ 0.05 ). Likewise, the former showed significant low IL-17 expression compared with seasonal flu ( P＜ 0.01 ) and health control ( P ＜0.001 ). Virus-negative ratio was different among three antiviral groups after a standard treatment course of 5days. The ratio was 92.86% for group Ⅲ, 71.43% for group Ⅰ and 46.15% for group Ⅱ in turn. Virusnegative ratio of the former two group was significantly higher than that of group Ⅱ ( P＜0.01, P ＜0.05 respectively). It took smaller hours of getting normathermia after treatment in group Ⅲ than that of the other two groups( P ＜ 0.05 ). Conclusion IL-17 and age are possibly interrelate with A (H1N1)flu virus infection and virus persistence. Oseltamivir combined traditional Chinese medicine treatment shows its unique advantage in antiviral efficacy and to alleviate the symptoms.

OBJECTIVETo investigate the effects of ulinastatin on lung injury in hemorrhagic shock rats.

METHODSTwenty-four normal SD rats were randomly divided into 3 groups (n=8), namely the control group, hemorrhagic shock group (group H) and ulinastatin group (group U). In group H and group U, blood was drawn from the femoral artery over a period of 10 min until a mean arterial pressure of 40 mmHg was obtained. Controlled hypotension was then maintained at 40-/+5 mmHg for 60 min by blood drawing or infusion when necessary. All the blood drawn and an equivalent volume of Ringer lactate solution were subsequently infused for resuscitation. Four hours after the resuscitation, the activity of superoxidedismutase (SOD), content of malondialdehyde (MDA), expression of heme oxygenase-1 (HO-1), wet to dry weight ratio (W/D), and pathologic changes of the lung tissues were measured or observed.

RESULTSCompared with those in the control group, the content of MDA, expression of HO-1 and W/D increased significantly in both group H and group U (P<0.05); these indexes in group U were significantly lower than those in group H (P<0.05). The activity of SOD in group U was significantly lower than that in the control group (P<0.05) but higher than that in group H (P<0.05). Optical microscopy demonstrated milder inflammatory cell infiltration and interstitial edema in the lung tissues in group U than in group H.

CONCLUSIONUlinastatin can lower the content of MDA, W/D and the expression of HO-1, increase the activity of SOD, and reduce histological lung injury in rats with hemorrhagic shock.

OBJECTIVETo investigate the cerebral uptake and regional distribution of propofol when plasma propofol concentration reaches equilibrium in the internal carotid artery and internal jugular vein in dogs.

METHODSEight male hybrid dogs aged 12-18 months weighing 10-12 kg were anesthetized with propofol at a single bolus (7 mg/kg) in 15 s followed by propofol infusion at a constant rate of 70 mg.kg(-1).h(-1) via the great saphenous vein of the right posterior limb. Blood samples were taken from the internal carotid artery and internal jugular vein at 30 min (T30) after propofol infusion for measurement of plasma propofol concentrations by high-pressure liquid chromatography (HPLC). The thalamus, epithalamus, metathalamus, hypothalamus, subthalamus, frontal lobe, parietal lobe, temporal lobe, hippocampus, cingulate gyrus, cerebellum, midbrain, pons, medulla oblongata and cervical cord were then dissected to determine propofol concentrations in these tissues by HPLC.

RESULTSThe propofol concentrations in the internal carotid artery and internal jugular vein blood plasma were comparable at T30 (6.16-/+1.02 vs 6.17-/+1.00 microg/ml, P>0.05). The propofol concentration was 6.11-/+1.07 microg/g in the epithalamus, 6.14-/+0.98 microg/g in the metathalamus, 6.12-/+1.02 microg/g in the hypothalamus, 6.15-/+1.00 microg/g in the subthalamus, 6.20-/+1.03 microg/g in the frontal lobe, 6.18-/+1.02 microg/g in the parietal lobe, 6.13-/+1.00 microg/g in the temporal lobe, 6.07-/+0.99 microg/g in the hippocampus, 6.14-/+1.06 microg/g in the cingulate gyrus, 6.15-/+1.00 microg/g in the cerebellum, 6.13-/+1.05 microg/g in the midbrain, 6.18-/+1.01 microg/g in the pons, 6.15-/+0.93 microg/g in the medulla oblongata, and 6.13-/+1.00 microg/g in the cervical cord, showing no significant differences in the distributions (P>0.05). Propofol concentration in the thalamus (8.68-/+0.88 microg/g) was significantly higher than those in the other brain tissues (P<0.05).

CONCLUSIONSAt the constant intravenous propofol injection rate of 70 mg.kg(-1).h(-1), plasma propofol concentration reaches equilibrium 30 min after the injection in the internal carotid artery and internal jugular vein with even distribution in the cerebral tissues in dogs, but the thalamus contains high propofol concentration.
