OBJECTIVES: Shelter hospital was an alternative way to provide large-scale medical isolation and treatment for people with mild coronavirus disease 2019 (COVID-19). Due to various reasons, patients admitted to the large shelter hospital was reported high level of psychological distress, so did the healthcare workers. This study aims to introduce a comprehensive and multifaceted psychosocial crisis intervention model. METHODS: The psychosocial crisis intervention model was provided to 200 patients and 240 healthcare workers in Wuhan Wuchang shelter hospital. Patient volunteers and organized peer support, client-centered culturally sensitive supportive care, timely delivery of scientific information about COVID-19 and its complications, mental health knowledge acquisition of non-psychiatric healthcare workers, group activities, counseling and education, virtualization of psychological intervention, consultation and liaison were exhibited respectively in the model. Pre-service survey was done in 38 patients and 49 healthcare workers using the Generalized Anxiety Disorder 7-item (GAD-7) scale, the Patient Health Questionnaire 2-item (PHQ-2) scale, and the Primary Care PTSD screen for the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (PC-PTSD-5). Forty-eight healthcare workers gave feedback after the intervention. RESULTS: The psychosocial crisis intervention model was successfully implemented by 10 mental health professionals and was well-accepted by both patients and healthcare workers in the shelter hospital. In pre-service survey, 15.8% of 38 patients were with anxiety, 55.3% were with stress, and 15.8% were with depression; 16.3% of 49 healthcare workers were with anxiety, 26.5% were with stress, and 22.4% were with depression. In post-service survey, 62.5% of 48 healthcare workers thought it was very practical, 37.5% thought more practical; 37.5% of them thought it was very helpful to relief anxiety and insomnia, and 27.1% thought much helpful; 37.5% of them thought it was very helpful to recognize patients with anxiety and insomnia, and 29.2% thought much helpful; 35.4% of them thought it was very helpful to deal with patients' anxiety and insomnia, and 37.5% thought much helpful. CONCLUSIONS Psychological crisis intervention is feasible, acceptable, and associated with positive outcomes. Future tastings of this model in larger population and different settings are warranted.

Objectives:To analyze the clinical characteristics, treatment effectiveness and long-term prognosis of childhood-onset lupus nephritis (LN), and to explore the risk factors for progression to end-stage renal disease (ESRD).Methods:In this retrospective study, the clinical data including general conditions, clinical manifestations, laboratory examinations, treatment, following up (till December 31st, 2020) and prognosis of 343 children with LN who were treated and followed up in the First Affiliated Hospital of Sun Yat-sen University from January 1, 2003 to December 31, 2019 were analyzed. Complete remission rates were compared between different pathological types according to renal biopsies and flare rates were compared between complete remission group and partial remission group according to the treatment effectiveness after 6 months of induction treatment. To investigate the risk factors of ESRD, the prognosis of flare and non-flare cases, and of cases with normal and elevated serum creatinine levels at baseline, was compared. Chi-squared tests were used for comparison between groups, and cumulative survival rate and renal survival rates were calculated by Kaplan-Meier survival analysis. Risk factors for ESRD were analyzed by COX regression model.Results:Among the 343 children, 68 were males (19.8%) and 275 were females (80.2%) with a median age of 13.0 (11.0, 16.0) years. Regarding the renal symptoms, 305 (88.9%) children had proteinuria and 245 (71.4%) had hematuria; while for extra-renal manifestations, 273 (79.6%) had anemia, 183 (53.4%) had rashes and 165 (48.1%) had fever. A total of 212 (61.8%) children had severely active SLE at initial presentation. After 6 months of induction treatment, the complete remission rate was 63.8% (219/343) and the partial remission rate was 27.1% (93/343). The complete remission rate was significantly higher in type Ⅰ and type Ⅱ LN compared to type Ⅳ LN (10/12 vs. 82/135 (60.7%), χ2 =3.936, P=0.047). One hundred and ten children who achieved remission, including complete remission and partial remission, experienced renal flare with a flare rate of 35.3% and a mean time to flare was (43.2±28.4) months. There was no significant difference in flare rates between complete and partial remission group (36.1% (79/219) vs. 33.3% (31/93), χ2=3.394, P=0.065). The follow-up time of all the children was 60.4 (32.3, 100.9) months. During the follow-up period, 15 children died and the cumulative survival rates at 3, 5 and 10 years were 97.2%, 96.4% and 93.3%, respectively; 14 children progressed to ESRD and the cumulative renal survival rates at 3, 5, and 10 years were 99.2%, 97.1%, and 93.4%, respectively. COX multivariate analysis demonstrated that elevated serum creatinine at baseline, nephritic flare and nephrotic flare were independent risk factors for progression of ESRD ( hazard ratio (HR)=3.575, 21.550 and 8.590, 95% CI 1.127-11.341, 2.394-194.027 and 1.042-70.823, P=0.031, 0.006, and 0.046, respectively). Conclusions:Children with LN are characterized by high SLE disease activity and multi-system involvement at onset. After 6 months of induction treatment, most of LN children could achieve clinical remission but some would experience renal flare. Nephritic flare, nephrotic flare and elevated serum creatinine at onset are independent risk factors for the progression of ESRD in children with LN.

Somatic symptom disorder (SSD) is a somatic disorder characterized by excessive anxiety over various somatic symptoms for a long time, which makes patients feel very painful and the quality of personal life significantly decreased. Previous studies have shown that there is a connection between the clinical manifestations of SSD patients and their cultural background. The patient in this case report was highly affected by Chinese yin-yang culture, displaying obvious Chinese characteristics. We report a patient with SSD, whose clinical manifestations were mainly sexual dysfunction and mood symptoms which were closely related to the Traditional Chinese culture of Yin and Yang. In this case, Hamilton Anxiety Scale, Hamilton Depression Scale, and International Erectile Function Questionnaire were used to evaluate the patients ' anxiety, depression, and sexual function, and the scores were 32, 33, and 9, respectively. The patient was treated with a combination of venlafaxine and mirtazapine. After 5 weeks of treatment, the patient's clinical symptoms improved significantly. The clinical manifestations of some Chinese SSD patients have obvious characteristic relevance to Chinese theory of Yin and Yang, making SSD easily to be misdiagnosed. Therefore, clinicians should pay atlention to this situation. In addition, the combination of venlafaxine and mirtazapine may have a better effect on SSD patients with chronic pain and sexual dysfunction.

Objective:To investigate the impact of different type of dyslipidemia on clinical and pathological characteristics in children with IgA nephropathy (IgAN).Methods:A retrospective study was performed at the Children Kidney Disease Center, the First Affiliated Hospital of Sun Yat-sen University between January 2006 to September 2019. Children diagnosed with primary IgAN was divided into dyslipidemia group and normal blood lipid group according to whether the blood lipid is normal, and was divided into the following four groups: hypercholesterolemia group, hypertriglyceridemia group, mixed hyperlipidemia group and low high-density lipoprotein cholesterol (HDL-C) group according to clinical classification. The clinical and pathological features in different groups were analyzed, and the risk factors of dyslipidemia were analyzed by using multivariate logistic regression analysis.Results:A total of 252 children with IgAN were enrolled in this study, including 169 males and 83 females, with a male/female ratio of 2.04∶1 and an age of (9.3±3.1) years. Among them, 34.5% IgAN children were complicated with hypertension, and 170 cases (67.5%) were in dyslipidemia group, 82 cases (32.5%) in normal blood lipid group. According to clinical classification, the children in dyslipidemia group were divided into hypercholesterolemia group (58 cases, 23.0%), hypertriglyceridemia group (16 cases, 6.3%), mixed hyperlipidemia group (77 cases, 30.6%) and low HDL-C group (19 cases, 7.5%). The systolic blood pressure, diastolic blood pressure, proportion of hypertension, blood urea nitrogen, uric acid and urinary protein in dyslipidemia group were higher than those in normal blood lipid group (all P<0.05), and the levels of serum albumin, blood IgA and estimated glomerular filtration rate (eGFR) were less (all P<0.05). The proportion of IgAN children in chronic kidney disease (CKD) stage 1 and CKD stage 2-5 with dyslipidemia was 65.0% and 84.4% respectively, and the proportion of IgAN children with CKD stage 2-5 in dyslipidemia group was higher than that in normal group ( P<0.05). The dyslipidemia group had a higher proportion of Lee Ⅲ-V grade than normal blood lipid group ( P<0.01). The results of Oxford pathological classification showed that the proportions of M1 and E1 in dyslipidemia group were higher than those in normal lipid group (all P<0.05), and there was no significant difference in segmental glomerulosclerosis, tubular atrophy or interstitial fibrosis and crescent between the two groups (all P>0.05). The comparison results between groups with different types of dyslipidemia showed that systolic blood pressure, diastolic blood pressure, serum uric acid and urinary protein in the mixed hyperlipidemia group were higher than those in other groups (all P<0.05), and the serum albumin level was less ( P<0.01). The results of Oxford pathological classification showed that the proportion of E1 in hypercholesterolemia group and mixed hyperlipidemia group was higher ( P<0.05). Multivariate logistic regression analysis showed that hypertension ( OR=2.734, 95% CI 1.327-5.632, P=0.006) and low serum albumin ( OR=0.838, 95% CI 0.791-0.889, P<0.001) were the risk factors of dyslipidemia in children with IgAN. Conclusions:In our center, 67.5% IgAN children are accompanied by dyslipidemia. The clinical manifestations and pathological changes of these dyslipidemia children are more severe than those with normal blood lipid, and the IgAN children with mixed hyperlipidemia are more notable. Hypertension and low serum albumin are the risk factors of dyslipidemia in children with IgAN.

Objective To analyze the expression and role of ubiquitin specific peptidase 18 (USP18) in gastric cancer cells,and to investigate the relationship between the development of gastric cancer and USP18.Methods The levels of USP18 protein and mRNA expression in immortalized gastric mucosa epithelial GSE cell lines and gastric cancer cell lines (AGS,MKN45,MKN25,BGC823,BGC803,SGC7901) were detected by using reverse transcription-polymerase chain reaction (RT-PCR) and Western blot,respectively.The role of USP18 in the invasion and proliferation of gastric cancer cells was analyzed by using CCK8 and Transwell assays.Results The mRNA level of USP18 was lower in GSE cell lines than that in gastric cancer cells (F =794.052,P ＜ 0.000 1).In six gastric cancer cell lines,mRNA level of USP18 was relatively high in BGC823 (17.62±0.55) and BGC803 (13.52±0.50) cell lines,and low in MKN28 (1.40±0.17) and MKN45 cell lines (4.23±0.26).As for the protein level,the expression of USP18 was lowest in GSE cell line.In six gastric cancer cell lines,the expression of USP18 was the highest in more aggressive SGC7901 and BGC803 cell lines and the lowest in AGS and MKN45 cells.Compared with the control group,interference of USP18 decreased the invasion and proliferation abilities of SGC7901 and BGC803 cell lines (P ＜ 0.01).Conclusion USP18 is highly expressed in more invasive gastric cancer cells,and the downregulation of USP18 can suppress the invasion and proliferation of gastric cancer cells.

Objective To improve the orotracheal intubation verifying technique and reduce the complication of backflow in rat experiment.Methods A new position evaluation of anti-backflow device was designed and made of safety IV catheter and closed IV catheter system.60 adult male Sprague Dawley rats 216±20 g were randomly assigned to two groups: group A (n=40) for verifying placement, group B (n=20) for anti-backflow test.Group A was further divided into group A1 using self-designed positioning device, group A2 using aerosol, group A3 taking cotton fiber for positioning judgment.The group B was divided into two subgroups, B1 and B2, counting escaped bubbles as a means of positioning observation, the difference is that group B1 using frustum of a cone shape anti-backflow device, while the group B2 using common airway tube.Routine endotracheal intubation was performed to observe and record the time of positioning, the location of exhalation phase, and the length of inspiratory phase countercurrent water column.The group A1 further performed tracheotomy under direct vision clearly to confirm the anatomic positioning status.Results During the exhalation cycle,three or more bubbles were observed to escape continuously, indicating that the intubation tube was properly placed and open in the airway.Positioning time: It took 1.75±1.02 respiratory cycles in group A1,3.30±0.95 respiratory cycles in group A2 and 4.10±0.99 respiratory cycles in group A3 to complete the assessment the positioning status.There was no statistically significant difference between groups A2 and A3 (P> 0.05).The time needed for group A1 was significantly shorter than that of groups A2 and A3 (P < 0.01).The longest countercurrent water column length in group B1 was 3.23±0.53 cm, and 8.48±1.01 cm in the group B2.Conclusions The new designed anti-backflow positioning evaluation device is a simple and convenient appliance to evaluate the location of orotracheal intubation in rat experiment.It can effectively improve the positioning efficiency and has practical application value.

Objective To observe the clinical efficacy of thermal electroacupuncture therapy in treating lumbodorsal myofascitis. Method Sixty-two patients with lumbodorsal myofascitis were randomized into a treatment group of 30 cases and a control group of 32 cases. The treatment group was intervened by thermal electroacupuncture therapy, while the control group was by orally taking Meloxicam tablets. The Visual Analogue Scale (VAS) was observed before and after treatment, and the clinical efficacies were compared.Result The total effective rate was 100.0% in the treatment group versus 78.1% in the control group, and the difference was statistically significant (P<0.05). The VAS scores were significantly changed after treatment in both groups (P<0.05). After treatment, the VAS score in the treatment group was significantly different from that in the control group (P<0.05).Conclusion Thermal electroacupuncture therapy is an effective approach in treating lumbodorsal myofascitis.

OBJECTIVETo investigate the clinical effect of Halo-vest head ring in the treatment of replantation of total scalp avulsion.

METHODSWe treated 11 cases of total scalp avulsion with the anastomosis of arteriovenous vessels and Halo-vest head ring from December 2006 to February 2015.

RESULTSOne patient's replanted scalp got necrosis because of serious contusion which was healed without hair growth after free skin graft and dressing. All the scalp flaps in the other 10 patients survived. After 3-96 months follow-up, the wound completely healed, the scalp and hair grew well with satisfactory appearance.

CONCLUSIONSThe use of Halo-vest head ring for replantation of total scalp avulsion can effectively improve the survival rate and survival area.

ObjectiveTo observe right ventricle (RV) structure and function of New Zealand rabbits with chronic intermittent hypoxia (CIH) for short-term (0-8 weeks) by echocardiography. MethodsTwenty-four healthy male New Zealand rabbits were set up CIH animal model for 8 weeks. RV structure?s systolic and diastolic function were measured by conventional and tissue Doppler echocardiography at 0, 1, 2, 4, 6 and 8 week and one rabbit was sacriifced randomly for RV myocytes and pulmonary tissue pathology examination. RV structure and function parameters at 0, 1, 2, 4, 6 and 8 week were analyzed by mixed effects model analysis.ResultsRV structure variables: RV, RA at 8 week increased compared with those at 0 week, but had no signiifcant difference (P>0.05); RV systolic function variables:RVFAC at 8 week increased compared with those at 0 week (F=3.45, P<0.05), TAPSE at 4, 6, 8 week increased compared with that at 0 week (F=3.11, 3.41 and 3.86, all P<0.05), RVMPI at 4 week decreased compared with that at 0 week (F=3.46, P<0.05), recovered to baseline at 6, 8 week. Isovolumetric relaxation time (IRTc) corrected by heart rate at 1, 2, 4 week decreased compared with that at 0 week (F=3.15, 3.31 and 3.17, all P<0.05), recovered to baseline at 8 week, ET of PA at 1, 2 week decreased compared with that at 0 week (F=3.01 and 3.15, both P<0.05), recovered to baseline at 4, 6, 8 week, AT of PA at 1, 2, 4 week decreased compared with that at 0 week (F=3.13, 3.15 and 3.32, all P<0.05), recovered to baseline at 6, 8 week. RV diastolic function variables: isovolumetric contraction time (ICTc) corrected by heart rate at 2, 4 week decreased compared with that at 0 week (F=3.13 and 3.33,both P<0.05), E/E? at 1, 2 week decreased compared with that at 0 week (F=3.13 and 3.44,bothP<0.05), recovered to baseline at 4, 6, 8 week, E/A at 4, 6, 8 week increased compared with that at 0 week (F=4.01, 3.82 and 3.37, all P<0.05), E?/A? at 8 week increased compared with that at 0 week (F=3.81, P<0.05). The myocardial pathology showed that RV myocardial cell structure was normal at 4 week. Nuclei enlarged, stain darkened and some cytoplasms loosed when exposed to CIH for 8 weeks. The structure of lung tissues was normal when exposed to CIH for 4 weeks. Inflammatory cell inifltrated, capillary engorged as well as the wall of pulmonary arterioles thickened slightly at 8 week.ConclusionsRV diastolic and systolic function showed compensatory and structure was normal in early CIH (0-8 week). RV diastolic function compensated earlier than systolic function. IRT and ICT were sensitive indicators of RV systolic and diastolic function compensation.
