ABSTRACT
With the accelerated aging society in China, the incidence of biliary surgical diseases in the elderly has increased significantly. The clinical characteristics of these patients indicate that improving treatment outcomes and realizing healthy aging are worthy of attention. How to effectively improve the treatment effect of geriatric biliary surgical diseases has attracted widespread attention. This paper reviews and comments on the hotspots and difficulties of biliary surgery in older patients from six aspects: (1) higher morbidity associated with an aging society, (2) prevention and control of pre-operative risks, (3) extending the indications of laparoscopic surgery, (4) urgent standardization of minimally invasive surgery, (5) precise technological progress in hepatobiliary surgery, and (6) guarantee of peri-operative safety. It is of great significance to fully understand the focus of controversy, actively make use of its favorable factors, and effectively avoid its unfavorable factors, for further improving the therapeutic effects of geriatric biliary surgical diseases, and thus benefits the vast older patients with biliary surgical diseases. Accordingly, a historical record with the highest age of 93 years for laparoscopic transcystic common bile duct exploration has been created by us recently.

BACKGROUND@#Screening using low-dose computed tomography (LDCT) is a more effective approach and has the potential to detect lung cancer more accurately. We aimed to conduct a meta-analysis to estimate the accuracy of population-based screening studies primarily assessing baseline LDCT screening for lung cancer.@*METHODS@#MEDLINE, Excerpta Medica Database, and Web of Science were searched for articles published up to April 10, 2022. According to the inclusion and exclusion criteria, the data of true positives, false-positives, false negatives, and true negatives in the screening test were extracted. Quality Assessment of Diagnostic Accuracy Studies-2 was used to evaluate the quality of the literature. A bivariate random effects model was used to estimate pooled sensitivity and specificity. The area under the curve (AUC) was calculated by using hierarchical summary receiver-operating characteristics analysis. Heterogeneity between studies was measured using the Higgins I2 statistic, and publication bias was evaluated using a Deeks' funnel plot and linear regression test.@*RESULTS@#A total of 49 studies with 157,762 individuals were identified for the final qualitative synthesis; most of them were from Europe and America (38 studies), ten were from Asia, and one was from Oceania. The recruitment period was 1992 to 2018, and most of the subjects were 40 to 75 years old. The analysis showed that the AUC of lung cancer screening by LDCT was 0.98 (95% CI: 0.96-0.99), and the overall sensitivity and specificity were 0.97 (95% CI: 0.94-0.98) and 0.87 (95% CI: 0.82-0.91), respectively. The funnel plot and test results showed that there was no significant publication bias among the included studies.@*CONCLUSIONS@#Baseline LDCT has high sensitivity and specificity as a screening technique for lung cancer. However, long-term follow-up of the whole study population (including those with a negative baseline screening result) should be performed to enhance the accuracy of LDCT screening.

OBJECTIVE@#To analyze the clinical phenotype and genetic variants of a child suspected for mitochondrial F-S disease.@*METHODS@#A child with mitochondrial F-S disease who visited Department of Neurology, Hunan Provincial children's Hospital on November 5, 2020 was selected as research subject of this study. Clinical data of the child was collected. The child was subjected to whole exome sequencing (WES). Bioinformatics tools were used to analyze the pathogenic variants. Candidate variants were verified by Sanger sequencing of the child and her parents.@*RESULTS@#WES revealed that the child has harbored compound heterozygous variants of the FDXR gene, namely c.310C>T (p.R104C) and c.235C>T (p.R79C), which were inherited from her father and mother, respectively. Neither variant has been reported in HGMD, PubMed, 1000 Genomes, and dbSNP databases. Both of the variants have been suggested as deleterious according to the prediction results from different bioinformatics analysis software.@*CONCLUSION@#Mitochondrial diseases should be suspected for patients with multiple system involvement. The compound heterozygous variants of the FDXR gene probably underlay the disease in this child. Above finding has enriched the spectrum of FDXR gene mutations underlying mitochondrial F-S disease. WES can facilitate the diagnosis of mitochondrial F-S disease at the molecular level.

Objective:To investigate correlation between neutrophil extracellular traps(NETs) formation and T cell subsets in mice with experimental autoimmune thyroiditis(EAT) and the impact of active vitamin D intervention.Methods:Six-week-old female BALB/c mice were randomly divided into Control group, EAT group and 1, 25 dihydroxy vitamin D 3[1, 25(OH) 2D 3] treatment group(VitD group; n=6/group). HE staining was used to observe thyroid pathology. Plasma thyroglobulin antibody(TGAb), thyroid peroxidase antibody(TPOAb), and 1, 25(OH) 2D 3 were measured by ELISA. Peripheral NETs formation, Th1, Th2, and Th17 cell ratio from spleen were measured by flow cytometry. Correlation between NETs formation rate and Th1, Th2, and Th17 cell ratio was analyzed. Results:Compared with Control group, mice in EAT group had significantly increased thyroid inflammation scores, thyroiditis morbidity, TPOAb, TGAb levels, NETs formation rate, Th2(CD4 + IL-4 + or CD4 + IL-13 + )and Th17 cell proportions( P were <0.001, 0.002, 0.007, <0.001, <0.001, 0.003, 0.001, and 0.002, respectively), and significant decreased 1, 25(OH) 2D 3, Th1 cell proportions, Th1/Th2(CD4 + IL-4 + ), Th1/Th2(CD4 + IL-13 + ), and Th1/Th17 ratios( P were 0.010, 0.018, 0.010, 0.005, and 0.007, respectively). Compared with the EAT group, the VitD group had lower thyroid inflammation scores, TPOAb, TGAb levels, NETs formation rate, Th2(CD4 + IL-4 + or CD4 + IL-13 + ) and Th17 cell proportions( P were 0.044, 0.007, <0.001, 0.001, 0.014, 0.008, and 0.001, respectively), and significant higher Th1 cell ratio, Th1/Th2(CD4 + IL-13 + ) and Th1/Th17 ratio( P were 0.011, 0.009, and 0.003, respectively). The Th1/Th2(CD4 + IL-4 + ) was not significantly increased in VitD group compared with EAT group( P=0.174). NETs formation rate was positively correlated with Th2(CD4 + IL-4 + or CD4 + IL-13 + ) and Th17 cell proportion( r were 0.65, 0.59, and 0.61; and P were 0.004, 0.010, and 0.007, respectively), but not with Th1 cell proportion( r=-0.47, P=0.051). Conclusion:EAT mice were more prone to NETs formation. Active vitamin D may relieve immune imbalance with increased Th2 and Th17 cell ratio and decreased Th1 cell ratio by reducing the formation of NETs in EAT mice. Vitamin D played the protective role in thyroid by reducing thyroid pathological damage and thyroid autoantibody levels, and relived overall lymphocyte imbalance.

Objective:To explore the effect of cupping combined with acupoint application on acute urinary retention (AUR) and its influences on detrusor function after anorectal surgery.Methods:Randomized controlled trial. A total of 120 patients in the hospital were enrolled as the observation objects between April 2020 and April 2022. According to random number table method, they were divided into two groups, 60 in each group. The control group was given acupoint application, while observation group was additionally given cupping. All were continuously treated for 3 days. Before and after treatment, urination function symptoms were scored. The pain degree was assessed by VAS. C-reactive protein (CRP) was detected by ELISA, and white blood cell count (WBC) was detected by blood routine analyzer. The bladder volume (CC), maximum flow rate (Q max), average flow rate (AFR) and residual urine volume (PVR) were evaluated by urodynamics analyzer. The adverse reactions were recorded, and clinical curative effect was evaluated. Results:The difference in total response rate between observation group and control group was statistically significant [91.67% (55/60) vs. 80.00% (48/60); χ2=4.90, P=0.027]. After treatment, scores of dysuria, frequency of urination, urgency of urination and VAS in observation group were significantly lower than those in the control group ( t=22.83, 8.70, 8.70, 17.26, P<0.01). After treatment, Q max [(10.85±3.49) ml/s vs. (8.13±2.74) ml/s, t=4.75], AFR [(5.40±1.42) ml/s vs. (3.68±1.51) ml/s, t=19.44] and CC [(352.69±51.75) ml/s vs. (396.57±58.16) ml/s, t=4.37] in observation group were significantly higher than those in the control group ( P<0.01), while PVR [(36.73±6.54) ml/s vs. (51.04±10.32) ml/s, t=9.07] was significantly lower than that of the control group ( P<0.01). The levels of serum CRP and WBC in observation group were significantly lower than those in the control group ( t=23.50, 5.05, P<0.01). The difference in the incidence of adverse reactions between observation group and control group was not statistically significant [6.67% (4/60) vs. 5.00% (3/60); χ2=0.15, P=0.697]. Conclusion:Cupping combined with acupoint application can improve detrusor function, relieve abnormal urination symptoms and improve curative effect in AUR patients after anorectal surgery, which is safe and reliable.

ABSTRACT
【Objective】 To explore and verify the mechanism of curcumin’s inhibition of the proliferation of renal clear cell carcinoma （RCCC） based on network pharmacology and bioinformatics. 【Methods】 We screened common target genes of RCCC and curcumin from PharmMapper and GeneCards databases. We used TCGA database data analysis to screen out common target genes which not only differentially expressed between RCCC tissue samples and normal tissue samples but also affected prognosis. We also used STRING platform to construct curcumin-RCCC targets interaction network， used R software to perform GO biological process analysis and KEGG pathway enrichment analysis based on the above-mentioned screening target proteins. After curcumin and/or active oxygen inhibitor N-acetyl-L-cysteine （NAC） were incubated in renal cancer 786-O and ACHN cells， CCK8 was used to detect the effects of different concentrations of curcumin on cell proliferation and cell viability. Reactive oxygen detection kit （DCFH-DA） was used to detect the level of intracellular reactive oxygen species， and malondialdehyde （MDA） determination kit （TBA method） to detect intracellular malondialdehyde changes. 【Results】 PharmMapper website and GeneCards database screened out 109 common targets of curcumin and RCCC. TCGA database data analysis screened out 37 differentially expressed genes （DEGs） that might affect the overall survival of patients. The core target proteins of curcumin screened out by protein-protein interaction （PPI） that inhibited the biological behavior of RCCC mainly involved CASP3， EGFR， CHEK1， HSP90AA1， and AR. GO enrichment analysis identified 213 items， mainly including reactive oxygen species metabolic process， response to steroid hormones， fibrinolysis and other biologically active processes. KEGG enrichment analysis identified 24 items， which were mainly related to pyruvate metabolism， glycolysis/gluconeogenesis， FoxO signaling pathway， colorectal cancer， tyrosine metabolism， IL-17 signaling pathway， apoptosis and other signaling pathways. Curcumin reduced the cell viability of 786-O and ACHN in a time- and dose-dependent manner （P<0.05）. After curcumin was incubated with kidney cancer cells， the level of reactive oxygen species and MDA increased significantly （P<0.05）. The addition of NAC reversed the effect of curcumin on the cell viability of 786-O and ACHN cells （P<0.05）. 【Conclusion】 Curcumin may participate in the oxidative stress pathway to inhibit the proliferation of renal cell carcinoma.

ABSTRACT
Since December 2019, corona virus disease 2019 (COVID-19) , an emerging infection disease occurred in Wuhan, has spread in the mainland China. The epidemic factors on the basis of knowledge of SARS-CoV-2 were discussed in this paper. This puts a lot of pressure on clinical resources and care. SARS-CoV-2 is a novel corona virus, the onset of COVID-19 is slow, and the pathogenesis of SARS-CoV-2 remains unclear and may lead to multiple organ damage. These put a lot of pressure on clinical resources and care. Source of infection including the patients, asymptomatic carrier and patients in the incubation period are contagious. It is difficult to control source of infection. Routes of SARS-CoV-2 transmission are diversified and the main routes of transmission for COVID-19 are droplet transmission and close contact transmission. All population have susceptibility to SARS-CoV-2. Social factors such population movements and aggregation accelerated the spread of SARS-CoV-2. The Chinese government’s adopted measures are positive and effective, and are accepted by the expert group from the World Health Organization. However, it will be a long-term hard work in the future to seriously summarize and think deeply to achieve public health security in China.

ABSTRACT
Since December 2019, Corona Virus Disease (COVID-19), a new emerging infection disease occurred in Wuhan, has spread in 27 countries and regions. The clusters of many cases were reported with the epidemic progresses. We collected currently available information for 377 COVID-19 clusters (1 719 cases), excluded the hospital clusters and Hubei cases, during the period from January 1, 2020 to February 20, 2020. There were 297 family clusters (79%), case median 4; 39 clusters of dining (10%), case median 5; 23 clusters of shopping malls or supermarkets (6%), case median 13; 12 clusters of work units (3%), case median 6, and 6 clusters of transportation. We selected 325 cases to estimate the incubation period and found its range is 1 to 20 days, median was 7 days, and mode was 4 days. The analysis of the epidemic situation in a department store in China indicates that there is a possibility of patients as the source of infection during the incubation period of the epidemic. From February 5, 2020 to February 21, 2020, 634 persons were infected in the Diamond Princess Liner. All persons are susceptible to SARS-CoV-2. The older, patients during the incubation period and the worse environment may be the cause of the cases rising. The progress of the two typical outbreaks clearly demonstrates the spread of the early cases in Wuhan. Whatever happens, screening and isolating close contacts remains essential except for clinical treatment during the epidemic. Especially for the healthy people in the epidemic area, isolation is the key.

ABSTRACT
Objective@#To summarize the clinical manifestations and gene variations of combined immunodeficiency caused by ORAI1 variation with a case report and literature review.@*Methods@#The clinical data of the patient who was diagnosed with ORAI1 variation caused combined immunodeficiency in the Department of Pediatrics in Xiangya Hospital of Central South University in February 2018 were extracted and analyzed. The literature till August 2018 was searched with key words of 'ORAI1', and 'immunodeficiency' in both English and Chinese in the database of China national knowledge infrast ructure (CNKI), Wanfang and Pubmed.@*Results@#The patient was a 15 months old girl with acute onset of bilateral ptosis after upper respiratory tract infection, which was rapidly progressed to systemic myasthenia and accompanied with recurrent respiratory tract infection during the treatment. The patient poorly to responded immunomodulatory therapy and anti-infection therapy. Laboratory tests demonstrated decreased complement C3 and NK cell (CD3-CD56+), increased anti-thyroglobulin, thyroid peroxidase antibody and B lymphocyte (CD3-CD19+), and slightly increased anti-acetylcholine receptor antibody. Genetic analysis showed the homozygous variation of ORAI1 gene exon l c.12 G>T (p.E4D), with heterozygostty of both parents. There were only 4 papers reporting this disease in the literature review. A total of 7 patients with ORAI1 gene variation were reported, including 3 homozygous variations, 2 heterozygous variations and 2 complex heterozygous variations. The clinical manifestations included early onset recurrent infection, congenital hypotonia, elevated serum IgA and IgM, decreased NK cells, and family history of hereditary diseases. Four of the 7 reported cases died of pulmonary infection and sepsis, and the other 3 survived with low muscular tone and poor self-care ability.@*Conclusions@#The most common clinical manifestations of ORAI1 variation caused combined immunodeficiency are recurrent infection and congenital hypotonia. Myasthenia induced recurrent respiratory tract infection is an important factor of poor prognosis in severe patients. There is a lack of effective treatment for this disease, and the prognosis is poor.
ABSTRACT
Objective To study the load transfer mechanics between residual limb and prosthetic socket, as well as stress distributions below the residual limb, so as to provide a theoretical basis for designing and optimizing of prosthetic socket and improving the wearing comfort. Methods Aiming at compression-release stabilization （CRS）, the finite element software ABAQUS was used to analyze the stress distribution at the interface between the residual limb and CRS socket. The soft tissues were defined using the Mooney-Rivlin function. The interface pressures and shear stresses between the residual limb and CRS socket during mid-stance were obtained. A three-dimensional finite element model of the patellar tendon bearing (PTB) socket was established, and the results were compared. Results The interface pressures between the residual limb and CRS socket were mainly distributed at lateral tibia, media tibia and popliteal depression regions, which were similar to the main force regions of PTB socket. The mean interface pressures on the end of stump for CRS socket was increased by 19 kPa over PTB socket. Conclusions CRS socket had better breathability and reasonable stress distributions. The stress distribution of biomechanical interface was different due to the different shapes of socket. Therefore, the optimization of prosthetic socket can help to improve the wearing comfort of prosthetic limbs.
