ABSTRACT

Objective:To compare the clinical efficacy and safety of conventional transcatheter arterial chemoembolization (TACE) with drug-eluting bead transcatheter arterial chemoembolization (DEB-TACE) in treatment of patients with unresectable hepatocellular carcinoma.Methods:The data of patients with unresectable hepatocellular carcinoma who underwent hepatic artery chemoembolization at General Hospital of Ningxia Medical University from July 2019 to April 2020 were retrospectively analyzed. Of 282 patients who were enrolled, there were 233 males and 49 females, aged (55.9±10.0) years. The groups were divided into the conventional TACE group ( n=179) and the DEB-TACE group ( n=103) based on the treatments. The efficacy of the two groups was compared according to the modified response evaluation criteria in solid tumors. Postoperative adverse effects and liver function between the two groups were compared. Results:The differences in comparing the preoperative and postoperative liver function indexes between the two groups were not statistically significant. Patients who died and were lost to follow-up at 6 months after surgery were excluded and 240 patients were excluded in the efficacy analysis, with 148 patients in the conventional TACE group and 92 patients in the DEB-TACE group. At 6 months after treatment in the conventional TACE group, there were 64 patients (43.2%) with complete remission, 18 patients (12.2%) with partial remission, 27 patients (18.2%) with stable disease, and 39 patients (26.4%) with disease progression. In the DEB-TACE group, the corresponding figures were 38 patients (41.3%), 17 patients (18.5%), 26 patients (28.3%), and 11 patients (12.0%), respectively. The efficacy of DEB-TACE was better than conventional TACE with statistically significant differences between the 2 groups (χ 2=8.96, P=0.030). The incidence of postoperative embolic syndrome was 53.1% (95/179) in the conventional TACE group, which was significantly higher than the 34.0% (35/103) in the DEB-TACE group (χ 2=7.34, P=0.007). Conclusion:The efficacy and safety of DEB-TACE for unresectable hepatocellular carcinoma were superior to those of the conventional TACE group.

ABSTRACT

AIM: To investigate the expression level of inflammatory factors of aqueous humor before trabeculectomy in binocular chronic primary angle-closure glaucoma(CPACG)and its correlation with postoperative filtration bleb and intraocular pressure.METHODS: A total of 15 cases(30 eyes)with binocular CPACG who admitted to the Affiliated Eye Hospital of Nanjing Medical University from September to December 2021 and received trabeculectomy were selected. The surgery interval between two eyes was 7d, and the preoperative expression levels of monocyte chemoattractant protein-1(MCP-1), interleukin-17(IL-17), transforming growth factor-β(TGF-β), and interferon-γ(IFN-γ)of the aqueous humor in both eyes were respectively detected by enzyme-linked immunosorbent assay(ELISA). Furthermore, the intraocular pressure(IOP)and the morphology of filtering blebs at 1mo after surgery were measured.RESULTS: The concentrations of MCP-1, IL-17, TGF-β, and IFN-γ in aqueous humor from the first eye before surgery were 330.4±46.2, 357.3±46.9, 2347.5±363.8 and 527.7±101.6pg/mL respectively, and those concentrations in aqueous humor from the fellow eye were 298.2±40.7, 309.1±53.5, 1938.3±426.0 and 628.2±104.9pg/mL respectively. The preoperative expression levels of inflammatory factors of aqueous humor in both eyes were statistically significant(P≤0.05). Furthermore, the expression levels of IL-17 and TGF-β in the aqueous humor of patients with CPACG correlated with IOP and the height of filtering blebs at 1mo after surgery(P<0.05).CONCLUSION: There may be changes in the expression levels of inflammatory factors of aqueous humor in the fellow eye after surgery of the first eye. Moreover, the preoperative expression level of IL-17 and TGF-β in aqueous humor possibly related to postoperative IOP and the height of filtering bleb.

ABSTRACT

Peripheral bacterial infections without impaired blood-brain barrier integrity have been attributed to the pathogenesis of Parkinson's disease (PD). Peripheral infection promotes innate immune training in microglia and exacerbates neuroinflammation. However, how changes in the peripheral environment mediate microglial training and exacerbation of infection-related PD is unknown. In this study, we demonstrate that GSDMD activation was enhanced in the spleen but not in the CNS of mice primed with low-dose LPS. GSDMD in peripheral myeloid cells promoted microglial immune training, thus exacerbating neuroinflammation and neurodegeneration during PD in an IL-1R-dependent manner. Furthermore, pharmacological inhibition of GSDMD alleviated the symptoms of PD in experimental PD models. Collectively, these findings demonstrate that GSDMD-induced pyroptosis in myeloid cells initiates neuroinflammation by regulating microglial training during infection-related PD. Based on these findings, GSDMD may serve as a therapeutic target for patients with PD.

ABSTRACT

OBJECTIVES@#To study the relationship between skeletal muscle mass index (SMI) and metabolic phenotypes of obesity in adolescents, and to provide a basis for the prevention and control of adolescent obesity and related metabolic diseases.@*METHODS@#A total of 1 352 adolescents aged 12 to 18 years were randomly selected by stratified cluster sampling in Yinchuan City from October 2017 to September 2020, and they were surveyed using questionnaires, physical measurements, body composition measurements, and laboratory tests. According to the diagnostic criteria for metabolic abnormalities and the definition of obesity based on the body mass index, the subjects were divided into four metabolic phenotypes: metabolically healthy normal weight, metabolically healthy obesity, metabolically unhealthy normal weight, and metabolically unhealthy obesity. The association between SMI and the metabolic phenotypes was analyzed using multivariate logistic regression.@*RESULTS@#The SMI level in the metabolically unhealthy normal weight, metabolically healthy obesity, and metabolically unhealthy obesity groups was lower than that in the metabolically healthy normal weight group (P<0.001). Multivariate logistic regression analysis showed that after adjusting for gender and age, a higher SMI level was a protective factors for adolescents to develop metabolic unhealthy normal weight, metabolically healthy obesity, and metabolically unhealthy obesity phenotypes (OR=0.74, 0.60, and 0.54, respectively; P<0.001).@*CONCLUSIONS@#Increasing SMI can reduce the risk of the development of metabolic unhealthy/obesity.

ABSTRACT

OBJECTIVE@#To analyze and compare the characteristics and causes of F wave changes in patients with Charcot-Marie-Tooth1A (CMT1A) and chronic inflammatory demyelinating polyneuropathy (CIDP).@*METHODS@#Thirty patients with CMT1A and 30 patients with CIDP were enrolled in Peking University Third Hospital from January 2012 to December 2018. Their clinical data, electrophysiological data(nerve conduction velocity, F wave and H reflex) and neurological function scores were recorded. Some patients underwent magnetic resonance imaging of brachial plexus and lumbar plexus, and the results were analyzed and compared.@*RESULTS@#The average motor conduction velocity (MCV) of median nerve was (21.10±10.60) m/s in CMT1A and (31.52±12.46) m/s in CIDP. There was a significant difference between the two groups (t=-6.75, P < 0.001). About 43.3% (13/30) of the patients with CMT1A did not elicit F wave in ulnar nerve, which was significantly higher than that of the patients with CIDP (4/30, 13.3%), χ2=6.65, P=0.010. Among the patients who could elicit F wave, the latency of F wave in CMT1A group was (52.40±17.56) ms and that in CIDP group was (42.20±12.73) ms. There was a significant difference between the two groups (t=2.96, P=0.006). The occurrence rate of F wave in CMT1A group was 34.6%±39%, and that in CIDP group was 70.7%±15.2%. There was a significant difference between the two groups (t=-5.13, P < 0.001). The MCV of median nerve in a patient with anti neurofascin 155 (NF155) was 23.22 m/s, the latency of F wave was 62.9-70.7 ms, and the occurrence rate was 85%-95%. The proportion of brachial plexus and lumbar plexus thickening in CMT1A was 83.3% (5/6) and 85.7% (6/7), respectively. The proportion of brachial plexus and lumbar plexus thickening in the CIDP patients was only 25.0% (1/4, 2/8). The nerve roots of brachial plexus and lumbar plexus were significantly thickened in a patient with anti NF155 antibody.@*CONCLUSION@#The prolonged latency of F wave in patients with CMT1A reflects the homogenous changes in both proximal and distal peripheral nerves, which can be used as a method to differentiate the CIDP patients characterized by focal demyelinating pathology. Moreover, attention should be paid to differentiate it from the peripheral neuropathy caused by anti NF155 CIDP. Although F wave is often used as an indicator of proximal nerve injury, motor neuron excitability, anterior horn cells, and motor nerve myelin sheath lesions can affect its latency and occurrence rate. F wave abnormalities need to be comprehensively analyzed in combination with the etiology, other electrophysiological results, and MRI imaging.

ABSTRACT

Objective:To document any effect of clinical rehabilitation pathway management on intubation time, dysfunction and medical expenditure associated with tracheotomy after a stroke.Methods:A total of 154 stroke survivors undergoing tracheotomy were randomly divided into an observation group and a control group, each of 77. Both groups were given routine rehabilitation, while the observation group was additionally provided with clinical rehabilitation pathway management during the rehabilitation intervention. Kaplan-Meier analysis was performed before the experiment and after 2, 4 and 6 weeks of treatment. Clinical pulmonary infection scores (CPISs), scores on the Chelsea Physical Function Assessment Scale (CPAx) and hospitalization cost were compared between the two groups.Results:The median extubation time of the observation group (2d) was significantly shorter than that of the control group (10d). After 2, 4 and 6 weeks of treatment, the average CPIS scores of the observation group were in each case significantly lower than those before treatment and the control group′s averages at the same time points, even though after 4 and 6 weeks of treatment the control group′s average CPIS scores had improved significantly. After 2, 4 and 6 weeks of treatment, the average CPAx scores of the observation group were significantly higher than those before treatment and better than the control group′s averages, even though the control group too had improved significantly compared with before the treatment. Hospitalization days, total hospitalization cost, antibiotic cost and laboratory examination cost of the observation group were, on average, significantly lower than those of the control group.Conclusion:Rehabilitation path management can shorten the period of intubation, prevent pulmonary infections, relieve dysfunction, and reduce medical expenses for stroke survivors after a tracheotomy. It is worthy of clinical promotion.

ABSTRACT

Objective:To explore any effect of upper limb swing training guided by rhythmic auditory stimulation (RAS) on the walking ability of stroke survivors.Methods:Eighty stroke survivors were randomly divided into an observation group and a control group. Both groups received conventional rehabilitation treatment, including neuromuscular facilitation, muscle strength training, balance training and gait training, but the observation group was additionally provided with RAS-guided upper limb swing training for 20min once a day, 5d per week for 6 weeks. Before and after the intervention, balance and lower limb function were quantified in both groups using Holden′s walking function classification, the Fugl-Meyer lower extremity motor function scale (FMA-LE), the Berg Balance Scale (BBS) and the 10m walk test (10MWT). Limits of stability were also quantified.Results:After the treatment, the average Holden, FMA-LE and BBS scores, as well as the average 10MWT time were significantly better in the observation group than in the control group. The average stability limits and their maintenance were also superior.Conclusion:RAS-guided upper limb swing training can improve the gait, walking ability, walking stability, walking speed and balance of stroke survivors.

ABSTRACT

Objective:To investigate any effect of repeated transcranial magnetic stimulation (rTMS) on the expression of P2X7 receptor (P2X7R) and glial fibrillary acid protein (GFAP) in the prefrontal cortex and hippocampus of mice modeling depression.Methods:Thirty C57BL/6 mice were divided into a control group ( n=10) and a depression group ( n=20). The mice of the control group were raised in group (five mice per cage), while those of the depression group were kept alone for six weeks to induce depression. Among them, 16 were successfully modeled and randomly divided into a model group ( n=8) and an rTMS group ( n=8). The rTMS group received five sessions per week of 10Hz rTMS for 4 weeks. Any changes in depression-like behavior were observed and the expression of P2X7R and GFAP in the prefrontal cortex and hippocampus was measured. Results:Compared to the control group, a significant decrease was observed in the sucrose consumption rate in the sucrose preference test, in the distance moved in the open field test and in the expression of GFAP protein. But there was a significant increase in the immobile time in the tail suspension test and in the expression of P2X7R protein in the prefrontal cortex and hippocampus in the model group. At the conclusion of the experiment the differences in the sucrose consumption rate, the distance moved, GFAP protein expression, immobile time and P2X7R protein expression between the rTMS and the model group were all statistically significant.Conclusion:rTMS can reduce depression-like behavior, at least in mice. That may be related to inhibiting P2X7R expression and promoting GFAP expression in the prefrontal cortex and hippocampus.

ABSTRACT

Objective:To explore the influence of interpregnancy interval (IPI) on pregnancy complications in multiparas.Methods:This was a retrospective cohort study involving 7 669 singleton parturients who delivered at ≥28 gestational weeks in the Affiliated Hospital of Southwest Medical University between December 2015 and December 2020 and had given birth in the third trimester before. Clinical data were collected, including the baseline characteristics, pregnancy complications, gestational weeks at delivery, and neonatal birth weight. According to the IPI, these women were divided into five groups: <12 months ( n=350), 12-<24 months ( n=945), 24-<60 months ( n=2 544), 60-<120 months ( n=2 478), and ≥120 months ( n=1 352). Based on the recommendation of the World Health Organization, pregnant women with an IPI of 24-<60 months were the control group. A multivariate logistic model was used to adjust for confounders and calculate the risks of pregnancy complications, including gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP). The influences of maternal age and previous delivery mode on the associations between IPI and maternal complications were analyzed. Analysis of variance (ANOVA), Chi-square test, and Cochran-Mantel-Haenszel Chi-square test were used for statistical analysis. Results:Compared with the control group, the incidence of GDM and HDP increased in the 60-<120 months group ( OR=1.23, 95% CI: 1.01-1.48 and OR=1.47, 95% CI: 1.13-1.92) and ≥120 months group ( OR=1.37, 95% CI:1.07-1.78 and OR=1.92, 95% CI: 1.39-2.64); the risks of uterine rupture/postpartum hemorrhage and placental abruption increased in the <12 months group ( OR=1.54, 95% CI: 1.01-2.34) and 12-<24 months group ( OR=2.38 95% CI: 1.13-5.02), respectively. In the 60-<120 months group, the risk of GDM increased only in non-elderly women (adjusted OR=1.71, 95% CI: 1.36-2.14), so did the risks of GDM and HDP in the ≥120 months group (adjusted OR=3.11, 95% CI: 2.10-4.62 and adjusted OR=1.81, 95% CI: 1.12-2.91). Among women who had undergone a previous cesarean section, the risk of GDM increased in the ≥120 months group (adjusted OR=1.35, 95% CI: 1.00-1.81). In the 60-<120 months group and ≥120 months group, the risk of HDP increased in postpartum women (adjusted OR=1.79, 95% CI: 1.08-2.95 and adjusted OR=3.32, 95% CI: 1.91-5.77). Conclusion:IPI≥60 months is a risk factor for GDM and HDP, and the associations between IPI and maternal complications are influenced by maternal age.

ABSTRACT

Clinical data of 102 patients with premature ovarian failure admitted to Zhang Zhongjing Hospital from December 2018 to December 2021 were retrospectively analyzed. Fifty-one patients received (control group), and another 51 patients received Chinse medicine Kuntai capsule in addition to sequential estrogen progesterone therapy(study group); both groups were treated for 3 menstrual cycles. After treatment, the total effective rate of the study group was higher than that of the control group (94.1% (48/51) vs. 72.6% (37/51), χ2=4.07, P=0.044). After treatment, the proportion of patients with mild Kupperman score and serum estradiol level in both groups were increased, and the proportion in study group was higher than that in the control group. The proportion of patients with moderate and severe Kupperman score and the total score decreased after treatment in both groups, and the proportion of patients with moderate Kupperman score in the study group was lower than that in the control group. Serum luteinizing hormone and folliclestimulating hormone levels were significantly decreased, and the levels in study group were lower than those in the control group. The levels of resistance index and PI were significantly decreased after treatment in both group and the study group decrease more markedly (all P<0.05). The peak systolic flow velocity level was increased after treatment in both groups and the study group increased more markedly (all P<0.05). It is suggested that the application of Chinese medicine Kuntai capsule combined with sequential estrogen progesterone therapy can effectively improve the clinical therapeutic effect, stabilize sex hormones, uterine microcirculation and effectively alleviate the condition of patients with premature ovarian failure.

ABSTRACT

Objective:To investigate the efficacy and safety of the "frame and buttress" fixation in the treatment of acetabular quadrilateral fractures.Methods:A total of 26 patients with acetabular quadrilateral fractures treated with the "Frame and buttress" fixation strategy (reconstructing frame and providing buttress for quadrilateral surface) from January 2017 to January 2021 were retrospectively analyzed in the Department of Orthopaedics, Union Hospital of Tongji Medical College, Huazhong University of Science and Technology, including 17 males and 9 females, aged 47.7±16.5 years, (range, 25-71 years). There were 13 cases from car accidents, 8 cases from falls, and 5 cases from heavy objects. Quadrilateral fractures were classified according to whether the anterior column (A) and posterior column (P) of the acetabulum were fractured and whether the quadrilateral plate (Q) was partially (1) or completely (2) separated from the two columns. Among these cases, there were 5 cases of type AQ1, 1 case of type AQ2, 1 case of type PQ2, 14 cases of type APQ1 and 5 cases of type APQ2. The "frame and buttress" fixation strategy was used to perform open reduction and internal fixation. The Matta scale was used to assess the quality of resurfacing based on pelvic radiographs, and the Matta modified Merle d'Aubigne and Postel scores were referenced to evaluate hip function.Results:All the 26 patients successfully completed the operation, the operation time was 88.1±57.8 min (range, 90-320 min), the intraoperative bleeding was 753.8±309.5 ml (range, 400-1 400 ml). There were 14 cases of anatomical reduction, 8 cases of satisfactory reduction and 4 cases of unsatisfactory reduction with an excellent rate of 85% (22/26), the excellence rate was 85% (22/26). All patients were followed up for 16.3±4.3 months (range, 12-24 months). The hip function score after operation was higher than that before operation, and the difference was statistically significant ( F=19.80, P<0.001). The hip function score was 13.1±2.2 at 3 months postoperatively, increased to 15.9±2.3 at 6 months postoperatively, and increased to 16.6±1.9 at the last follow-up, with a statistically significant difference ( P<0.001). After operation, 5 patients showed symptoms of lateral femoral cutaneous nerve injury such as hypoesthesia and numbness in the anterolateral thigh. During the follow-up, there was no ectopic ossification, traumatic arthritis, necrosis of the femoral head and central dislocation of the femoral head. Conclusion:The "frame and buttress" fixation strategy based on quadrilateral fracture typing for acetabular quadrilateral fracture open reduction internal fixation provides strong fixation, satisfactory reduction quality, and facilitates joint function recovery after operation.

ABSTRACT

Objective:To explore the value of ultrasound-based radiomics combined with clinical parameters in predicting lymph node metastasis of endometrial cancer.Methods:The clinical data and preoperative ultrasound images of 255 patients with endometrial cancer diagnosed after operation in the First Affiliated Hospital of Guangxi Medical University from January 2017 to February 2021 were analyzed retrospectively. The boundary of the tumor, that is, the region of interest(ROI), was determined manually by ITK-SNAP software, and the features were extracted from it. Through random sampling, the data were divided into training group used to build the model and verification group used to evaluate the reliability of the model at the proportion of 7∶3.In the training group, the spearman correlation coefficient was used as the threshold of 0.95 to remove the features with high correlation. The importance of the features were ranked by the decision tree model, the features of the top 6% importance were selected to establish a logical regression model, and then calculated the Radiomics score of each patient. On the basis of logical regression analysis, a comprehensive prediction model was established, the line diagram was drawn, and the prediction effect was evaluated by the analysis of the area under the subject working curve (AUC), calibration curve and the decision curve.Results:After dimensionality reduction and logical regression analysis, 20 features and 2 clinical parameters (CA125, CA153) were obtained to build the model. The AUC of training group and verification group in radiomics model and comprehensive prediction model were 0.81, 0.78 and 0.89, 0.85, respectively. The decision curve analysis showed that both of them had good clinical utility.Conclusions:The ultrasound-based radiomics model and the comprehensive model combined with relevant clinical parameters are effective in predicting lymph node metastasis of endometrial cancer.

ABSTRACT

Cervical cancer is a serious threat to women's life and health. Studies have shown that the incidence of cervical cancer in China ranks second in the world. With increasing application of cervical cancer screening technology, cervical cancer mortality shows a downward trend, but the incidence of cervical cancer in young women shows an upward trend. The affected population tends to be young. Young women are the population at high risk for a human papillomavirus (HPV) infection because they have high levels of estrogen and active sexual behavior. Persistent high-risk HPV infection is the key factor that promotes development of precancerous lesions toward cervical cancer. This paper reviews the clinical characteristics of HPV infection in young women and the research progress in diagnosis and treatment strategy of precancerous lesions.

ABSTRACT

Objective To investigate the effect of upstream transcription factor 2 (USF2) on the proliferation and apoptosis of human gastric cancer BGC-823 cells. Methods Lipofectamine?3000 transfection reagent was used to transfect USF2 siRNA into BGC-823 cells (siRNA-USF2 group). Blank control and negative control (siRNA-NC) groups were also prepared. The mRNA and protein expression levels of USF2 in transfected BGC-823 cells were detected by real-time fluorescence quantitative PCR and Western blot, respectively. The proliferation and clone formation abilities of BGC-823 cells in each group were investigated by CCK-8 and plate cloning assay. The apoptosis of gastric cancer cells was examined by flow cytometry. The expression levels of PCNA and apoptosis-related proteins Bax and Bcl-2 in BGC-823 cells were measured by Western blot. Results Compared with those in the blank control and siRNA-NC groups, the mRNA and protein expression levels of USF2 significantly decreased in the siRNA-USF2 group (P < 0.05). At 72 h after transfection, the absorbance in the siRNA-USF2 group was lower than that in the blank control group (P < 0.05). Compared with that in the blank control and siRNA-NC groups, the number of BGC-823 cell clones significantly decreased in the siRNA-USF2 group (P < 0.05). The apoptosis rate of BGC-823 cells significantly differed among the blank control, siRNA-NC, and siRNA-USF2 groups (P < 0.05). Compared with those in the blank control and siRNA-NC groups, the expression of PCNA and Bcl-2 protein decreased and that of Bax protein increased in the siRNA-USF2 group (P < 0.05). Conclusion Inhibiting USF2 expression can suppress the proliferation of human gastric cancer cells and induce their apoptosis. USF2 inhibitors may have important value in the treatment of gastric cancer.

ABSTRACT

Objective To understand the situation of cancer screening of community residents and its association with the knowledge of cancer core knowledge, and to provide reference for the formulation of secondary cancer prevention measures. Methods A cross-sectional survey was conducted among 2 037 residents aged 18-79 who lived in Bao 'an District, Shenzhen. Multivariate Logistic regression analysis was used to investigate the relationship between core knowledge and cancer screening behavior after adjusting for age, gender, education, marriage, occupation and smoking. Results The cancer screening rate of community residents was 28.10%, and the screening rate of middle-aged and elderly people aged 40-79 was 33.50 %.The proportion of “not very well understanding”, “partial understanding” and “basic understanding” of the core knowledge of cancer were 43.91%, 42.33% and 13.76%, respectively, which was higher than that of the non-participants. Multivariate analysis showed that the women, the higher the level of education of college/university or above and the higher the level of knowledge of cancer prevention core knowledge, the higher the probability of participating in cancer screening was OR (95%CI ) : 2.40 (1.86-3.12), 1.65 (1.29-2.10), 1.38 (1.18 - 1.62), respectively. Conclusion The proportion of cancer screening in community residents needs to be improved, and the degree of core knowledge of cancer is closely related to cancer screening behavior. It is suggested to increase the publicity and education of the core knowledge of cancer, and at the same time, carry out the health education of secondary cancer prevention for the key population such as men and people with low education level, so as to improve the proportion of “early detection, early diagnosis and early treatment” of cancer.

ABSTRACT

With the increasing incidence of upper gastric cancer and early gastric cancer, surgeons have gradually paid attention to the selection of appropriate digestive tract reconstruction methods. At present, the safety of surgery is no longer the main aim pursued by surgeons, and the focus of surgery has gradually changed to postoperative quality of life. Surgical procedures for upper gastric cancer include total gastrectomy (TG) and proximal gastrectomy (PG). Roux-en-Y anastomosis is recommended for digestive tract reconstruction after TG. The classic method of digestive tract reconstruction after PG is distal residual stomach and esophageal anastomosis. However, to prevent esophageal reflux caused by PG, a lot of explorations have been carried out over the years, including tubular gastroesophageal anastomosis, double-flap technique (Kamikawa anastomosis), interposition jejunum, double-tract reconstruction and so on. But the appropriate method of digestive tract reconstruction for upper gastric cancer is still controversial. In this paper, based on literatures and our clinical experience, the selection, surgical difficulties and techniques of digestive tract reconstruction after PG are discussed.

ABSTRACT

OBJECTIVE@#To explore the mechanism by which berberine inhibits ferroptosis of mouse hippocampal neuronal cells (HT22).@*METHODS@#Cultured HT22 cells were pretreated with 30 or 60 μmol/L berberine for 2 h before exposure to 0.5 μmol/L erastin for 8 h, and the cell proliferation, intracellular ferric iron level, changes in intracellular reactive oxygen species (ROS) and cell apoptosis were detected using CCK-8, Fe2+ fluorescent probe, fluorescent dye (DAPI) and fluorescent probe (H2DCFH-DA). RT-qPCR and Western blotting were used to detect the mRNA and protein expressions of Nrf2, HO-1 and GPX4 in the cells. We further tested the effects of treatments with 2 μmol/L ML385 (a Nrf2 inhibitor), 60 μmol/L berberine and erastin in the cells to explore the protective mechanism of berberine against erastin-induced ferroptosis in the neuronal cells.@*RESULTS@#Treatment with 0.5 μmol/L erastin significantly lowered the viability of HT22 cells (P < 0.05) and increased the production of ROS, cell apoptosis rate and ferric iron level (P < 0.05). Pretreatment with 30 and 60 μmol/L berberine both significantly increased the vitality of erastin-exposed cells (P < 0.05) and lowered the levels of intracellular ROS and ferric iron content (P < 0.05). RT-qPCR and Western blotting showed that berberine obviously promoted the expressions of Nrf2, HO-1 and GPX4 in the cells (P < 0.05), and treatment with ML385 significantly inhibited the Nrf2-HO-1/GPX4 pathway, increased intracellular ROS and ferric iron contents and mitigated the protective effect of berberine against erastin-induced ferroptosis (P < 0.05).@*CONCLUSION@#Berberine can inhibit erastin-induced ferroptosis in HT22 cells possibly by activating the Nrf2-HO-1/ GPX4 pathway.

ABSTRACT

Objective@#The scientific community knows little about the long-term influence of coronavirus disease 2019 (COVID-19) on olfactory dysfunction (OD). With the COVID-19 pandemic ongoing worldwide, the risk of imported cases remains high. In China, it is necessary to understand OD in imported cases.@*Methods@#A prospective follow-up design was adopted. A total of 11 self-reported patients with COVID-19 and OD from Xi'an No. 8 Hospital were followed between August 19, 2021, and December 12, 2021. Demographics, clinical characteristics, laboratory and radiological findings, and treatment outcomes were analyzed at admission. We surveyed the patients via telephone for recurrence and sequelae at the 1-, 6-, and 12-month follow-up.@*Results@#Eleven patients with OD were enrolled; of these, 54.5% (6/11) had hyposmia and 45.5% (5/11) had anosmia. 63.6% (7/11) reported OD before or on the day of admission as their initial symptom; of these, 42.9% (3/7) described OD as the only symptom. All patients in the study received combined treatment with traditional Chinese medicine and Western medicine, and 72.7% (8/11) had partially or fully recovered at discharge. In terms of OD recovery at the 12-month follow-up, 45.5% (5/11) reported at least one sequela, 81.8% (9/11) had recovered completely, 18.2% (2/11) had recovered partially, and there were no recurrent cases.@*Conclusions@#Our data revealed that OD frequently presented as the initial or even the only symptom among imported cases. Most OD improvements occurred in the first 2 weeks after onset, and patients with COVID-19 and OD had favorable treatment outcomes during long-term follow-up. A better understanding of the pathogenesis and appropriate treatment of OD is needed to guide clinicians in the care of these patients.

ABSTRACT

INTRODUCTION@#We aimed to compare the early clinical manifestations, laboratory results and chest computed tomography (CT) images of COVID-19 patients with those of other community-acquired pneumonia (CAP) patients to differentiate CAP from COVID-19 before reverse transcription-polymerase chain reaction results are obtained.@*METHODS@#The clinical and laboratory data and chest CT images of 51 patients were assessed in a fever observation ward for evidence of COVID-19 between January and February 2020.@*RESULTS@#24 patients had laboratory-confirmed COVID-19, whereas 27 individuals had negative results. No statistical difference in clinical features was found between COVID-19 and CAP patients, except for diarrhoea. There was a significant difference in lymphocyte and eosinophil counts between COVID-19 and CAP patients. In total, 22 (91.67%) COVID-19 patients had bilateral involvement and multiple lesions according to their lung CT images; the left lower lobe (87.50%) and right lower lobe (95.83%) were affected most often, and all lesions were located in the peripheral zones of the lung. The most common CT feature of COVID-19 was ground-glass opacity, found in 95.83% of patients, compared to 66.67% of CAP patients.@*CONCLUSION@#Diarrhoea, lymphocyte counts, eosinophil counts and CT findings (e.g. ground-glass opacity) could help to distinguish COVID-19 from CAP at an early stage of infection, based on findings from our fever observation ward.
