OBJECTIVESTo study the effectiveness of an artificial liver support system.

METHODSThirty-two patients with medicamentous liver insufficiency were treated with an artificial liver support system in addition to the routine medicinal therapy. Thirty patients treated with routine medicinal therapy only served as controls.

RESULTSThe clinical symptoms (e.g. hepatic encephalopathy) and the laboratory indices (serum total bilirubin and prothrombin time) of the treatment group patients were obviously improved compared with those of the control group patients (P < 0.05). The cure rate and hospitalization days were 90.6% (26/32) and 47 days respectively in the treatment group, and 43.3% (13/30) and 72 days in the control group (P < 0.05).

CONCLUSIONUsing an artificial liver support system combined with routine medicinal therapy is more effective than using medication alone.

OBJECTIVEThe study was to evaluate the method of early laser intervention of hemangioma in facial and neck regions of infant.

METHODSBetween January 1999 and December 2006, twelve patients, aged 6 days to 3 months, with cutaneous hemangioma in facial and neck regions, were treated with laser, eight cases with Nd:YAG laser therapy and four cases with Venus laser therapy. Four cases with hemangioma in facial and neck regions of infant treated with oral corticosteroid were as control. The outcome was recorded with 1 to 6 years of follow-up.

RESULTSTotal resolution was obtained in twelve patients with laser intervention. Atrophic scars occurred in eight patients with Nd:YAG laser therapy, without other complications, such as ulceration, life-threatening hemorrhage and et al. No scar occurred in four patients with Venus laser therapy. Recurrence was not seen in twelve cases with laser therapy with follow-up. Hemangiomas enlarged continuously in four cases with oral corticosteroid therapy.

CONCLUSIONEarly laser intervention is an excellent management of cutaneous hemangioma in facial and neck regions of infant.

OBJECTIVETo design and manufacture a reliable spine phantom used in the cross calibration and quality control of dual X-ray absorptiometry (DXA).

METHODSA hydroxyapatite quality control phantom was designed and made through three steps: solid water, bone phantom material and integration, then evaluated the phantom on four different types of DXA machines made by LUNAR company.

RESULTSAmong the four DXA densitometers, the Expert fan beam densitometer had the biggest accuracy errors of bone mineral density (BMD), bone mineral content(BMC) and area values while the other three one narrow fan beam (Prodigy) and two pencil beam densitometers-had small errors. Of the three indexes measured by all the machines, BMD error was the smallest (-15.4%-11.5%), with the Prodigy's BMD was most outstanding. BMD errors at the higher density ends were small, tend to be positive values while the errors at the lower ends were big, tend to be negative. In cross calibration, giving consideration to the differences between the both ends, it is better to use the regression equation to correct. The base line of precision error derived by scanning the phantom once a day for consecutive 25 days was better than that derived by scanning the phantom 25 times consecutively on the same day. As to precision error, the coefficient of variation (CV) of scanning-25 times-a day was the smallest (0.0043) while the CV of 12 adults measurements was the biggest (0.0078).

CONCLUSIONSThis phantom can be used in the quality control and cross-calibration of different types of DXA machines.

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.

OBJECTIVETo investigate the value of single photon emission computed tomography(SPECT)-computed tomography(CT) in diagnosis of oral carcinoma invasion to mandible.

METHODSThirty-four patients with oral carcinoma invasion to mandible were divided into two groups, group A (surrounding invasion) and group B (central invasion). The edge of the invasion was evaluated by SPECT-CT, CT and pathological examination. The results of CT and SPECT-CT were analyzed by quantitative methods.

RESULTSIn group A, the cancer-invaded area of the mandible exhibited on SPECT-CT was 1.0 cm lager than that on pathological examination, 2.4 cm lager than that on CT. The difference of invaded area shown on CT was 1.4 cm smaller than that of pathological examination. There were significant difference among the three methods. In group B, the affected area on SPECT-CT was 1.2 cm lager than that of pathological examination, 4.2 cm lager than that of CT. The invision area on CT was 3.0 cm smaller than that of pathological examination. There were significant difference among the three methods.

CONCLUSIONSSPECT-CT could find the jaw central tumor earlier than CT and the range of lesion showed by SPECT-CT was the adequate range of bone incision during operation. The range of lesion showed by CT was influenced by the type of tumor and the range of bone incision was determined according to the pathological type. If the false negative result was eliminated, only SPECT-CT or CT was needed to estimate the invasion range of mandible.

OBJECTIVETo study the alterations and relationship of surfactant protein (SP)-A, SP-D and KL-6 in serum and bronchoalveolar lavage fluids (BALF) in children with Mycoplasma pneumoniae pneumonia (MPP).

METHODSelf-control method was used for the study on SP-A, SP-D and KL-6 in serum, infected and non-infected BALFs in 32 MMP children with only one side of MPP.

RESULTThe contents of SP-A, SP-D and KL-6 in infected BALF were [mg/L;M (IQR) ]: 243 (90-468) , 187 (43-333) , 148 (47-426) ;104 (37-257) , 56 (25-131) , 35 (12-147) in non-infected BALF; 35 (25-69) , 33 (9-149) and 24 (15-62) in serum. The correlation coefficient of KL-6 between serum and infected BALF were -0.534 and -0.378 (P < 0.05).

CONCLUSIONThere were significant correlation between the alterations of SP-A, SP-D and KL-6 in serum and lung infection in children with CAP. KL-6 in serum may be more sensitive than SP-A and SP-D.

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.

Objective To investigate the effect of cinobufacini on inhibiting colorectal cancer metastasis by regula-ting the polarization of M2 macrophages.Methods THP-1 was induced into M0 type macrophages.The condi-tioned medium of HCT116 cells was collected to stimulate M0 type macrophages.The polarization of M2 type mac-rophages was observed by flow cytometry,real-time quantitative PCR and ELISA experiments.The conditioned me-dium of M0 type macrophages and HCT116-Mφ cells was collected to stimulate HCT116 cells.The ability of migra-tion and invasion was observed by wound healing assay and Transwell assay.The effect of cinobufacini on the via-bility of HCT116 cells was detected by CCK-8 assay.The conditioned medium of HCT116 and HCT116+cinobufa-cini was collected to stimulate M0 type macrophages.The polarization of M2 type macrophages was observed by flow cytometry,real-time quantitative PCR and ELISA experiments.The conditioned media of HCT116-Mφ cells and(HCT116+cinobufacini)-Mφ cells were collected to stimulate HCT116 cells.The changes of migration and inva-sion ability were observed by wound healing assay and Transwell assay.Results After stimulation of M0 type mac-rophages in HCT116 cell conditioned medium,the morphology of M0 macrophages turned into fusiform cells,the proportion of CD11b+CD206+cells increased,and the expression of M2 macrophage markers IL-10 and TGF-β in-creased.The migration and invasion ability of HCT116 cells were significantly enhanced after stimulation in the conditioned medium of HCT1 16-Mφ cells.After the addition of cinobufacini,not only the polarization proportion of M2 macrophages decreased,but also the metastatic effect mediated by M2 macrophages was inhibited.Conclusion HCT116 cells can induce the polarization of M2 macrophages,while cinobufacini can inhibit the tumor metastasis mediated by M2 macrophages by inhibiting the polarization of M2 macrophages.

PURPOSE: To investigate the prevalence of spina bifida occulta (SBO) and its relationship with the presence of overactive bladder (OAB) in middle-aged and elderly people in China. METHODS: A cross-sectional community-based survey was carried out at 7 communities in Zhengzhou City, China from December 15, 2013 to June 10, 2014, where residents aged over 40 years were randomly selected to participate. All of the participants underwent lumbosacral radiographic analysis and relevant laboratory tests. A questionnaire including basic information, past medical history and present illness, and the OAB symptom score was filled out by all participants. Chi-square tests and logistic regression were used for data analysis with a P-value of <0.05 denoting statistical significance. RESULTS: A total of 1,061 subjects were qualified for the final statistical analysis (58.8±11.7 years; male, 471 [44.4%]; female, 590 [55.6%]). The overall prevalence of SBO was 15.1% (160 of 1,061): 18.3% (86 of 471) in men and 12.5% (74 of 590) in women. Among these subjects, 13.7% (145 of 1,061) had OAB: 13.2% (62 of 471) in men and 14.1% (83 of 590) in women. The results of logistic regression showed that age, SBO, history of cerebral infarction (HCI), and constipation were risk factors for OAB (P<0.05), while sex, history of childhood enuresis (HCE), body mass index (BMI), and diabetes mellitus (DM) were not (P>0.05). In men, age, SBO, and constipation were risk factors for OAB (P<0.05), while HCE, BMI, DM, HCI, and benign prostate hyperplasia were not (P>0.05). In women, age, SBO, and HCI were risk factors for OAB (P<0.05), while HCE, BMI, DM, vaginal delivery, and constipation were not (P>0.05). CONCLUSIONS: The prevalence of SBO is high and it is related to OAB in middle-aged and elderly people in China.
