ABSTRACT
Early colorectal cancers refer to invasive cancers that have infiltrated into the submucosa without invading muscularis propria, and approximately 10% of these patients have lymph node metastases that cannot be detected by conventional imaging. According to the guidelines of Chinese Society of Clinical Oncology (CSCO) Colorectal Cancer, early colorectal cancer cases with risk factors for lymph node metastasis (poor tumor differentiation, lymphovascular invasion, deep submucosal invasion and high-grade tumor budding) should receive salvage radical surgical resection; however, the specificity of this risk-stratification is inadequate, making most patients undergo unnecessary surgery. Firstly, this review focuses on the definition, oncological impact importance and controversy of the above "risk factors". Then, we introduce the progress of the risk stratification system for lymph node metastasis in early colorectal cancer, including the identification of new pathological risk factors, the construction of new risk quantitative models based on pathological risk factors, artificial intelligence and machine learning technology and the discovery of novel molecular markers associated with lymph node metastasis based on gene test or liquid biopsy. Aim to enhance clinicians' understanding of the risk assessment of lymph node metastasis in early colorectal cancer; we suggest to take the patient's personal situation, tumor location, anti-cancer intention and other factors into account to make individualized treatment strategies.

AIM: To observe the characteristics of microperimetry in patients with glaucoma, and investigate the correlation between microperimetry and best corrected visual acuity(BCVA), standard automatic perimetry and optical coherence tomography(OCT)index.METHODS: This case-control study included 45 patients(76 eyes)with glaucoma(glaucoma group), among which 15 patients(25 eyes)with primary open-angle glaucoma and 30 patients(51 eyes)with chronic angle-closure glaucoma, and 40 healthy individuals(76 eyes)were included in the control group. MAIA microperimetry, Humphrey perimetry, and BCVA tests were performed in all examined eyes. Correlation analysis was performed using the structural indices measured by OCT.RESULTS: The mean sensitivity(MS)in macular area measured by microperimetry and the ganglion cell complex(GCC)and retinal nerve fiber layer(RNFL)thickness measured by OCT were decreased in glaucoma patients when compared to the control group. Additionally, the mean defect(MD)measured by Humphrey perimetry(10-2 visual field test), focal loss volume(FLV), global loss volume(GLV)measured by OCT, and 63% bivariate contour ellipse area(BCEA )measured by MAIA microperimetry were higher than those of the control group. The MS was negatively correlated with MD, FLV, GLV and BCVA(LogMAR)in the glaucoma group(rs=-0.839, -0.665, -0.530, and -0.424, all P<0.01). In contrast, MS was positively correlated with GCC and RNFL in the glaucoma group(rs=0.437, 0.500, all P<0.01). MAIA microperimetry had a shorter detection time. Receiver operating characteristic(ROC)curve analysis showed that MAIA microperimetry had moderate accuracy for the diagnosis of glaucoma.CONCLUSIONS: MAIA microperimetry has high sensitivity and can detect retinal sensitivity reduction in areas of structural damage tested by OCT. The microperimetry values were correlated with BCVA, standard automatic perimetry parameters, and OCT parameters. MAIA microperimetry combined with OCT will increase the early diagnosis rate of glaucoma.
ABSTRACT
Objective:To investigate the correlations of endoscopic evaluation results with laboratory indices and clinical disease activity in Crohn disease (CD) patients with different intestinal involvement.Methods:Data of 147 patients diagnosed as having CD who visited the Department of Gastroenterology, Zhongnan Hospital of Wuhan University from July 1, 2017 to June 30, 2022 were collected retrospectively. According to the involvement of intestinal segment, patients were divided into three groups: the group with isolated small intestinal involvement ( n=55), the group with both small intestinal and large intestinal involvement ( n=48), and the group with isolated large intestinal involvement ( n=44). Correlations of endoscopic evaluation (based on CDEIS) with laboratory indices and clinical disease activity (based on Harvey-Bradshaw index) were analyzed. Results:C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) could be used for the prediction of endoscopic disease activity. The areas under curve (AUC) of receiver operator characteristic (ROC) were 0.677 (0.506-0.849) and 0.744 (0.597-0.890), respectively. In terms of determing clinical disease activity, clinical Harvey-Bradshaw index was consistent with endoscopic CDEIS score in 65.3% (96/147) patients, showing a low positive correlation ( r=0.260, P<0.05). In subgroup analysis for patients with isolated small intestinal involvement, CRP showed no predictive value for clinical disease activity [AUC (95% CI): 0.617 (0.461-0.773), P=0.148], while for endoscopic activity neither CRP nor ESR showed predictive value [AUC (95% CI): 0.537 (0.146-0.929), P=0.829; AUC (95% CI): 0.571 (0.153-0.990), P=0.680]. Furthermore, for patients with isolated small intestinal involvement and both small intestinal and large intestinal involvement, no correlation was found between clinical Harvey-Bradshaw index and endoscopic CDEIS score ( r=0.222, P=0.092; r=0.142, P=0.322). Conclusion:For CD patients with small intestinal involvement, especially isolated small intestinal involvement, laboratory indices and clinical disease activity cannot accurately reflect endoscopic disease activity. Great importance should be attached to evaluation of the extent and activity of intestinal lesions by endoscopy, especially enteroscopy.

Objective:To investigate the effects of high-flux versus low-flux hemodialysis on end-stage renal disease in older adults and evaluate its effects on myocardial injury indexes and micro-inflammatory response indexes. Methods:Seventy-two patients with ESRD who received treatment in Affiliated Hospital of Shaoxing University from January 2019 to January 2020 were included in this study. They were randomly assigned to receive either low-flux hemodialysis (control group, n = 36) or high-flux hemodialysis (observation group, n = 36). All patients received 6 months of treatment. Micro-inflammatory response indexes and renal function indexes pre- and post-treatment, and reverse reactions were observed in each group. Results:Serum interleukin-6, tumor necrosis factor α, and high-sensitivity C-reactive protein levels post-treatment in the observation group were (7.16 ± 1.32) ng/L, (2.10 ± 0.36) pg/L, (2.20 ± 1.06) mg/L respectively, which were significantly lower than those in the control group [(10.45 ± 1.42) ng/L, (5.22 ± 0.65) pg/L, (3.84 ± 1.57) mg/L, t = 10.19, 25.19, 5.19, all P < 0.001]. Serum parathyroid hormone, B-type natriuretic peptide, and cardiac troponin T levels post-treatment in the observation group were (520.36 ± 95.65) pmol/L, (0.45 ± 0.10) μg/L, (15.05 ± 6.37) ng/L, respectively, which were significantly lower than those in the control group [(830.25 ± 102.35) pmol/L, (0.85 ± 0.13) μg/L, (30.25 ± 6.59) ng/L, t = 13.27, 14.63, 9.95, all P < 0.001]. The total response rate was significantly higher in the observation group than in the control group [75.00% (27/36) vs. 47.22% (19/36), χ2 = 3.85, P < 0.05]. The overall incidence of adverse reactions was significantly lower in the observation group than in the control group [19.44% (7/36) vs. 41.67% (15/36), χ2 = 4.18, P < 0.05). Conclusion:High-flux hemodialysis can highly improve the control effect of micro-inflammatory responses and alleviate myocardial injury in older adult patients with end-stage renal disease. High-flux hemodialysis is more effective and safer than low-flux hemodialysis.

ABSTRACT
Haining City and Jiashan County in Zhejiang Province are the first areas to carry out colorectal cancer screening in China, which started in the early 1970s and has been going on for more than 40 years. Meanwhile, Haining and Jiashan have also become the first batch of National Demonstration Bases for Early Diagnosis and Treatment of Colorectal Cancer. In the past 40 years, owing to Professor Zheng Shu who is brave and innovative, with an indomitable spirit, as well as the unremitting efforts and active exploration of all the team members, colorectal cancer screening which was unknown by the public and implemented with difficulties, has gradually been widely accepted and benefited the population. Today, remarkable achievements have been fulfilled in the colorectal cancer screening of Haining and Jiashan which has become the pioneer power in promoting the progress of colorectal cancer prevention and control in China and has certain influence both on China and the world. Meanwhile, a set of colorectal cancer screening strategies suitable for China has been explored and further promoted to be used nationwide, which is of great significance to the prevention and control of colorectal cancer in China. Looking forward to the future, the prevention and control of colorectal cancer in China is still difficult. We will continue to give full play to our existing advantages, not forget our original intention, move forward, explore innovation, and create greater glories!

Objective:To investigate the clinical practice of chronic kidney disease-mineral and bone disorder (CKD-MBD) in maintenance hemodialysis patients in Shanghai, and to better understand the changes of clinical practice for CKD-MBD.Methods:Sixty-four hospitals with qualified dialysis center in Shanghai were selected for questionnaire survey as of March 2019. The survey questionnaire included the number of hemodialysis and peritoneal dialysis patients, the implementation of CKD-MBD guidelines, the learning of CKD-MBD guidelines, the detection and distribution of CKD-MBD biochemical indicators, the treatment of hyperphosphatemia, the treatment of secondary heperparathyroidism (SHPT) and renal bone disease, and the concentration of calcium ion in dialysate. The results were compared with previous survey data in 2011.Results:There were sixty-three hospitals included in this study, with 10 168 maintenance hemodialysis patients and 4 610 maintenance peritoneal dialysis patients in Shanghai. 84.1%(53/63) hospitals implemented the guidelines smoothly, which increased by 28.5% compared with the rate (55.6%) of 2011. The successful implementation rates for guidelines in secondary and tertiary hospitals were 83.3%(25/30) and 84.8%(28/33) , which increased by 44.0% and 11.7% respectively (39.3% of secondary hospitals and 73.1% of tertiary hospitals in 2011). All hospitals carried out the detection for serum calcium and phosphorus. The rate for parathyroid hormone (PTH), total alkaline phosphatase (AKP), bone specific alkaline phosphatase (BAP), 25-hydroxy vitamin D[25(OH)D], and other bone metabolism-related biomarkers were 98.4%(62/63), 90.5%(57/63), 19.0%(12/63), 90.5%(57/63) and 42.9%(27/63), respectively; coronary artery CT, lumbar lateral X-ray plain, echocardiography, bone mineral density, and vascular ultrasound were carried out in 68.3%(43/63), 74.6%(47/63), 100.0%(63/63), 68.3%(43/63)and 69.8%(44/63), respectively. Compared with 2011, the proportion of detection for PTH, AKP, BAP, 25(OH)D, coronary artery CT, lumbar lateral film and echocardiography increased by 2.1%, 1.6%, 0.5%, 47.9%, 14.6%, 20.9% and 1.9%, respectively. The proportion of patients with serum phosphorus ranging in 0.80-1.45 mmol/L(KDIGO guideline), serum phosphorus ranging in 0.80-1.78 mmol/L(KDOQI guideline), calcium ranging in 2.10-2.54 mmol/L, and PTH ranging in 150-600 ng/L were 37.0%(3 323/8 969), 50.7%(4 571/9 018), 60.2%(5 568/9 244) and 33.2%(3 018/9 087). Compared with 2011(39.6%, 53.5% and 34.1%), the proportion of patients with ideal serum phosphorus (0.80-1.78 mmol/L) and calcium (2.10-2.54 mmol/L) levels increased by 11.1% and 6.7% respectively, and the proportion with PTH 150-300 ng/L decreased by 0.9%. The proportion of hospitals for using non-calcium phosphate binders (lanthanum carbonate from 1.9% to 87.3% and sevelamer carbonate from 14.8% to 63.5%) and surgical treatment (from 38.9% to 68.3%) for SHPT dramatically increased.Conclusions:Through the availability of medicine increases, and nephrologists gain deeper understanding in management and treatment of CKD-MBD, the detection rate for CKD-MBD indicators and the eligible rate have significantly improved compared with those in 2011. However, the comprehensive management of CKD-MBD in Shanghai still faces great challenges. It is still necessary to further improve eligible rate for serum phosphorus and iPTH, so as to provide more evidences and management strategies for integrated management of end-stage renal disease and prevention of abnormal calcium and phosphorus metabolism in patients.
ABSTRACT
This study explored the molecular mechanism underlying the Gegen Qinlian Decoction(GQD) promoting the differentiation of brown adipose tissue(BAT) to improve glucose and lipid metabolism disorders in diabetic rats. After the hypoglycemic effect of GQD on diabetic rats induced by high-fat diet combined with a low dose of streptozotocin was confirmed, the total RNA of rat BAT around scapula was extracted. Nuclear transcription genes Prdm16, Pparγc1α, Pparα, Pparγ and Sirt1, BAT marker genes Ucp1, Cidea and Dio2, energy expenditure gene Ampkα2 as well as BAT secretion factors Adpn, Fndc5, Angptl8, IL-6 and Rbp4 were detected by qPCR, then were analyzed by IPA software. Afterward, the total protein from rat BAT was extracted, and PRDM16, PGC1α, PPARγ, PPARα, SIRT1, ChREBP, AMPKα, UCP1, ADPN, NRG4, GLUT1 and GLUT4 were detected by Western blot. The mRNA expression levels of Pparγc1α, Pparα, Pparγ, Ucp1, Cidea, Ampkα2, Dio2, Fndc5, Rbp4 and Angptl8 were significantly increased(P<0.05) and those of Adpn and IL-6 were significantly decreased(P<0.05) in the GQD group compared with the diabetic group. In addition, Sirt1 showed a downward trend(P=0.104), whereas Prdm16 tended to be up-regulated(P=0.182) in the GQD group. IPA canonical pathway analysis and diseases-and-functions analysis suggested that GQD activated PPARα/RXRα and SIRT1 signaling pathways to promote the differentiation of BAT and reduce the excessive lipid accumulation. Moreover, the protein expression levels of PRDM16, PGC1α, PPARα, PPARγ, SIRT1, ChREBP, AMPKα, UCP1, GLUT1, GLUT4 and NRG4 were significantly decreased in the diabetic group(P<0.01), which were elevated after GQD intervention(P<0.05). Unexpectedly, the expression of ADPN protein in the diabetic group was up-regulated(P<0.01) as compared with the control group, which was down-regulated after the administration with GQD(P<0.01). This study indicated that GQD promoted BAT differentiation and maturity to increase energy consumption, which reduced the glucose and lipid metabolism disorders and thereby improved diabetes symptoms.

OBJECTIVES@#To investigate the attitudes and skills of grief counseling in the front-line medical workers from coronavirus disease 2019 (COVID-19) designated hospitals in Wuhan for the bereaved family members and to provide the basis for proper hospital management strategies.@*METHODS@#The convenience sampling method was applied to select 422 medical workers who kept touch with the bereaved family members in five COVID-19 designated hospitals in Wuhan from January to February 2020. Questionnaire regarding grief counseling attitudes and questionnaire regarding grief counseling skills were used to evaluate the attitudes and skills of grief counseling in medical workers. The scores of grief counseling attitudes and skills in group of different characteristics were further compared. Pearson correlation was used to analyze the attitudes and skills of grief counseling in medical workers.@*RESULTS@#The scores of grief counseling attitudes in medical workers were 15-46 (33.00±9.31). Length of service, professional title, whether or not receiving relevant training, frequency of contact with bereaved family members contributed to impacting the medical workers' attitudes of grief counseling (all <0.05). The scores of grief counseling skills in medical workers were 9-30 (19.30±4.42). Length of service, professional title, religion, whether or not receiving relevant training, frequency of contact with bereaved family members contributed to impacting the medical workers' skills of grief counseling (all <0.05). There was a significant positive correlation between the attitudes and skills of grief counseling in the medical workers (=0.608, <0.01).@*CONCLUSIONS@#The attitudes and skills of grief counseling in the medical workers from COVID-19 designated hospitals in Wuhan still need to be improved. Grief counseling group and a long-term, comprehensive training system are recommended.

OBJECTIVE@#To evaluate the efficacy of Chinese medicine acupoint application (CMAA) combined with Western medicine for perennial allergic rhinitis (PAR) in children.@*METHODS@#In this prospective, parallel, randomized, placebo-controlled and single-blind trial from August to September, 2017, 180 children with PAR were randomly assigned to an integrative group (CMAA and Montelukast), CMAA group (CMAA and placebo tablet), or Montelukast group (placebo CMAA and Montelukast). Participants were applied with CMAA for 6 sessions over 2 weeks, and/or Montelukast Chewable Tablet orally once daily for 12 weeks. The changes in severity of symptoms were measured by Visual Analog Scale (VAS) and rhinitis control assessment test (RCAT) at 0, 2, 4 and 12 weeks of treatment. Blood samples were collected for serum interleukin-4, interferon gamma γ and T helper type 1 (Th1)/Th2 flow cytometric analysis at the time points of 0, 4 and 12 weeks.@*RESULTS@#Eight cases dropped out from the trial, 3 in the integrative group, 2 in the CMAA group and 3 in the Montelukast group. The VAS scores decreased significantly while the RCAT scores increased significantly in all three groups at 4 and 12 weeks compared with baseline (P<0.01 or P<0.05). The VAS scores were significantly lower while the RCAT scores were significantly higher in the integrative and CMAA groups than the Montelukast group at 2 and 4 weeks (P<0.01 or P<0.05). At 2, 4 and 12 weeks, the scores of nasal congestion, sneezing, sleep problem, and rhinitis symptom control in the integrative and CMAA groups increased significantly compared with baseline (P<0.01 or P<0.05). The least percentages of Th2 and the most alleviated Th2 shift (highest Th1/Th2) were observed in the integrative group at 12 weeks compared with the other two groups (P<0.05).@*CONCLUSION@#The combination of CMAA with Montelukast might be more effective and appropriate than either option alone for children with PAR.

ABSTRACT
Objective To investigate the correlation between the source of Schistosoma japonicum infections and sociological factors among mobile populations in Haining City, so as to provide insights into the management of schistosomiasis among mobile populations in Haining City. Methods A total of 12 villages were randomly sampled from 8 townships and 4 subdistricts in Haining City. The mobile populations from schistosomiasis-endemic areas were detected for S. japonicum infections using serological tests. In addition, the awareness of schistosomiasis prevention and control knowledge was investigated using a questionnaire survey. Results A total of 1 019 mobile populations were investigated in 12 villages from Haining City, and 23 sero-positives were found, with a positive rate of 2.26%; however, no egg-positives were detected. Logistic regression analysis showed that the mobile populations with original occupations of aquaculture and husbandry were more likely to be sero-positive. The mobile populations had an overall low awareness rate of schistosomiasis prevention and control knowledge, and a higher rate was seen in sero-positive than in sero-negatives. Conclusions The mobile populations with original occupations of aquaculture and husbandry were the key for the surveillance of source of S. japonicum infections. The health education should be intensified to improve the awareness of schistosomiasis prevention and control knowledge among mobile populations.

ABSTRACT
Objective:To discuss the topical action characteristics of the biological transmission of moxibustion heat via temperature collection and numerical modeling.Methods:Temperature of moxibustion was measured at multiple points at a distance of 3 cm to obtain the moxibustion temperature field nephograms by the high-accuracy temperature measure array.Finite element analysis was used to imitate the three-dimensional dynamic distribution of temperature in acupoint tissues.Results:Through numerical analysis,the one-dimensional,two-dimensional and three-dimensional distributions of temperature in human acupoint tissues at 5 min of moxibustion were established.The result showed that moxibustion heat mainly transmitted from the surface of the tissue to the internal,and the influence of moxibustion heat decreased with the depth of the tissue.The analysis of the nephograms of acupoint tissue temperature at 5,10,15 and 20 min of moxibustion showed that with the increase of the moxibustion time,the temperature in acupoint tissues constantly rose,and the transmission depth of moxibustion heat also further expanded inside acupoint.Conclusion:By establishing the three-dimensional dynamic model of heat transmission inside acupoint tissues with the biological parameters of human tissues and the temperature values obtained,this study used finite element analysis software ANSYS 14.0 and discovered the rules in the transmission of heat in body tissues during moxibustion,and the features in moxibustion heat transmission (from the proximal to the distant) and heat penetration (from the surface to the internal).This study provides theoretical and experimental support for the application of moxibustion in clinical practice.
ABSTRACT
OBJECTIVE@#To explore the value of galactose-deficient IgA1 (Gd-IgA1) in the early diagnosis of Henoch-Schönlein purpura nephritis (HSPN) in children.@*METHODS@#A total of 67 hospitalized children who were definitely diagnosed with HSPN between January and April 2018 and 58 hospitalized children with Henoch-Schönlein purpura (HSP) were enrolled in the study. Twenty children undergoing routine physical examinations served as controls. The levels of serum and urine Gd-IgA1 were determined using ELISA. The receiver operating characteristic curve was used to analyze the value of serum Gd-IgA1 and urine Gd-IgA1/urine creatinine ratio in the diagnosis of HSPN.@*RESULTS@#The level of serum Gd-IgA1 and urine Gd-IgA1/urine creatinine ratio in children with HSP or HSPN were significantly higher than those in healthy control group (P<0.01), with a significantly greater increase observed in children with HSPN (P<0.01). Serum Gd-IgA1 ≥1 485.57 U/mL and/or urine Gd-IgA1/urine creatinine ratio ≥105.74 were of favorable value in the diagnosis of HSPN. During the six-month follow-up of the 49 children with HSP, the incidence of HSPN was 47% (23/49), which included a 100% incidence in children with serum Gd-IgA1 ≥1 485.57 U/mL and a 73% incidence in children with urine Gd-IgA1/urine creatinine ratio ≥105.74.@*CONCLUSIONS@#Serum and urine Gd-IgA1 is of favorable clinical value in the early diagnosis of HSPN.

ABSTRACT
Objective@#To analyze the correlation between serum HBV DNA level and HBsAg titer in hepatitis B e antigen positive pregnant women without antiviral therapy, and investigate the impact of genomic variability of preS/S regions on their correlations.@*Methods@#Prenatal serum samples from 882 pregnant women with chronic HBV infection who were positive for HBsAg, HBeAg and HBV DNA and were not on antiviral therapy were included in the analysis. The Abbott i2000 and m2000 systems were used to qualitatively or quantitatively detect HBsAg, HBeAg and HBV DNA levels, respectively. HBV genotyping was performed using a type-specific primer nested polymerase chain reaction (nPCR). In addition, serum samples of pregnant women with HBV DNA levels correlated with HBsAg titer and HBV DNA levels higher than HBsAg titers were used to perform preS/S region amplification by nPCR method. PCR products were directly sequenced and mutation sites were analyzed by MEGA6.0 stasticial software. Mann-Whitney U test was used for the measurement data, and 2-test test for count data. Correlations between variables were analyzed using Spearman’s rank correlation.@*Results@#Serum HBsAg titer of HBeAg-positive pregnant women was positively correlated with HBV DNA level (r = 0.754, P < 0.01). Compared with the control group, mutation sites A60V (100% vs. 15.38%, χ2 = 7.61, P < 0.01), V90A (100% vs. 30.77%, χ2 = 4.43, P < 0.05) and I161T of HBV preS/S region (80.00% vs. 0, χ2 = 9.14, P < 0.01) showed a significant decrease in HBsAg titer.@*Conclusion@#Serum HBV DNA levels were positively correlated with HBsAg titer in HBeAg-positive pregnant women. Therefore, serum HBsAg titer may be used as a surrogate marker of serum HBV DNA. Single or multiple amino acid mutations sites A60V, V90A, and I161T in preS/S region may be one of the reasons that lead to a significant drop in HBsAg titer and affect its correlation with HBV DNA levels.
