ABSTRACT
BACKGROUND:The renin-angiotensin system plays a key role in the occurrence and development of hypertension,in which angiotensin(1-7)has antihypertensive effect and reversely regulates the adverse effects of angiotensin Ⅱ.Exercise rehabilitation therapy is an important non-pharmaceutical means to prevent and treat hypertension;however,whether angiotensin(1-7)and exercise have a synergistic effect is not yet clear. OBJECTIVE:To explore the effect of angiotensin(1-7)supplementation combined with exercise therapy on cardiac remodeling in rats with renal hypertension and to investigate the possible mechanism of angiotensin(1-7)and its receptor signal axis. METHODS:Sixty male Sprague-Dawley rats were selected,of which 12 rats were randomly selected as normotensive group and the remaining 48 rats were used to make animal models of renal hypertension using two-kidney one-clip method and were then randomly divided into hypertension control group,hypertension exercise group,angiotensin(1-7)group and combined treatment group.One week after successful modeling,different interventions were given(for a period of 6 weeks)as follows:the hypertension exercise group was subjected to a running training on an electric treadmill,the angiotensin(1-7)group was perfused with angiotensin(1-7)by implanting Alzet microosmotic pump subcutaneously on the back of the rats,and the combined treatment group was perfused with angiotensin(1-7)after running training,while the normotensive group and hypertension control group were caged quietly.At 48 hours after the last training session,the tail artery blood pressure was measured with a non-invasive sphygmomanometer;the heart structure and function were detected by echocardiography;the left ventricular myocardium was taken for histopathological observation by hematoxylin-eosin and Masson staining,and the cardiomyocyte cross-sectional area and collagen volume fraction were obtained by image analysis software as markers of myocardial hypertrophy and fibrosis,respectively;the content of angiotensin(1-7)in the heart was detected by high performance liquid chromatography;the mRNA expression of cardiac embryonic genes,atrial natriuretic peptide and β-myosin heavy chain,was detected by real-time fluorescence quantitative PCR;and the protein expression of cardiac Mas receptor,angiotensin Ⅱ type 2 receptor and endothelial nitric oxide synthase was measured by western blot assay. RESULTS AND CONCLUSION:Compared with the normotensive group,blood pressure increased(P<0.05),cardiac function had no significant changes(P>0.05),cardiomyocyte cross-sectional area and collagen volume fraction increased(P<0.05),mRNA expression of atrial natriuretic peptide and β-myosin heavy chain was upregulated(P<0.05),angiotensin(1-7)content and protein expression of Mas receptor,angiotensin Ⅱ type 2 receptor and endothelial nitric oxide synthase was downregulated(P<0.05)in the hypertension control group.Compared with the hypertension control group,blood pressure decreased(P<0.05),cardiac function improved(P<0.05),collagen volume fraction decreased(P<0.05),cardiomyocyte cross-sectional area and angiotensin(1-7)content showed no significant changes(P>0.05),mRNA expression of atrial natriuretic peptide and β-myosin heavy chain was downregulated(P<0.05),and the protein expression of Mas receptor,angiotensin Ⅱ type 2 receptor and endothelial nitric oxide synthase was upregulated(P<0.05)in the hypertension exercise group;except for an increase in myocardial angiotensin(1-7)content(P<0.05),other parameters had no statistical significance(P>0.05)in the hypertension angiotensin(1-7)group.Compared with the hypertension exercise group,blood pressure decreased(P<0.05),cardiomyocyte cross-sectional area and cardiac function had no significant changes(P>0.05),collagen volume fraction decreased(P<0.05),angiotensin(1-7)content increased(P<0.05),mRNA expression of atrial natriuretic peptide and β-myosin heavy chain was downregulated(P<0.05),and the protein expression of Mas receptor,angiotensin Ⅱ type 2 receptor and endothelial nitric oxide synthase was upregulated(P<0.05)in the combined treatment group.To conclude,supplementation of angiotensin(1-7)alone cannot improve cardiac remodeling in rats with renal hypertension,but it can enhance the efficacy of exercise.The mechanism is related to the improvement of angiotensin(1-7)receptor deficiency and restoration of its signaling pathway function.
ABSTRACT
Objective: To analyze the clinicopathologic characteristics and prognosis of testicular diffuse large B-cell lymphoma (DLBCL) . Methods: A retrospective analysis was performed on 68 patients with testicular DLBCL admitted to Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine from October 2001 to April 2020. The gene mutation profile was evaluated by targeted sequencing (55 lymphoma-related genes) , and prognostic factors were analyzed. Results: A total of 68 patients were included, of whom 45 (66.2% ) had primary testicular DLBCL and 23 (33.8% ) had secondary testicular DLBCL. The proportion of secondary testicular DLBCL patients with Ann Arbor stage Ⅲ-Ⅳ (P<0.001) , elevated LDH (P<0.001) , ECOG score ≥ 2 points (P=0.005) , and IPI score 3-5 points (P<0.001) is higher than that of primary testicular DLBCL patients. Sixty-two (91% ) patients received rituximab in combination with cyclophosphamide, adriamycin, vincristine, and prednisone (R-CHOP) -based first-line regimen, whereas 54 cases (79% ) underwent orchiectomy prior to chemotherapy. Patients with secondary testicular DLBCL had a lower estimated 5-year progression-free survival (PFS) rate (16.5% vs 68.1% , P<0.001) and 5-year overall survival (OS) rate (63.4% vs 74.9% , P=0.008) than those with primary testicular DLBCL, and their complete remission rate (57% vs 91% , P=0.003) was also lower than that of primary testicular DLBCL. The ECOG scores of ≥2 (PFS: P=0.018; OS: P<0.001) , Ann Arbor stages Ⅲ-Ⅳ (PFS: P<0.001; OS: P=0.018) , increased LDH levels (PFS: P=0.015; OS: P=0.006) , and multiple extra-nodal involvements (PFS: P<0.001; OS: P=0.013) were poor prognostic factors in testicular DLBCL. Targeted sequencing data in 20 patients with testicular DLBCL showed that the mutation frequencies of ≥20% were PIM1 (12 cases, 60% ) , MYD88 (11 cases, 55% ) , CD79B (9 cases, 45% ) , CREBBP (5 cases, 25% ) , KMT2D (5 cases, 25% ) , ATM (4 cases, 20% ) , and BTG2 (4 cases, 20% ) . The frequency of mutations in KMT2D in patients with secondary testicular DLBCL was higher than that in patients with primary testicular DLBCL (66.7% vs 7.1% , P=0.014) and was associated with a lower 5-year PFS rate in patients with testicular DLBCL (P=0.019) . Conclusion: Patients with secondary testicular DLBCL had worse PFS and OS than those with primary testicular DLBCL. The ECOG scores of ≥2, Ann Arbor stages Ⅲ-Ⅳ, increased LDH levels, and multiple extra-nodal involvements were poor prognostic factors in testicular DLBCL. PIM1, MYD88, CD79B, CREBBP, KMT2D, ATM, and BTG2 were commonly mutated genes in testicular DLBCL, and the prognosis of patients with KMT2D mutations was poor.

This study aims to observe the effects of diosgenin on the expression of mammalian target of rapamycin(mTOR), sterol regulatory element-binding protein-1c(SREBP-1c), heat shock protein 60(HSP60), medium-chain acyl-CoA dehydrogenase(MCAD), and short-chain acyl-CoA dehydrogenase(SCAD) in the liver tissue of the rat model of non-alcoholic fatty liver disease(NAFLD) and explore the mechanism of diosgenin in alleviating NAFLD. Forty male SD rats were randomized into five groups: a control group, a model group, low-(150 mg·kg~(-1)·d~(-1)) and high-dose(300 mg·kg~(-1)·d~(-1)) diosgenin groups, and a simvastatin(4 mg·kg~(-1)·d~(-1)) group. The rats in the control group were fed with a normal diet, while those in the other four groups were fed with a high-fat diet. After feeding for 8 weeks, the body weight of rats in the high-fat diet groups increased significantly. After that, the rats were administrated with the corresponding dose of diosgenin or simvastatin by gavage every day for 8 weeks. The levels of triglyceride(TG), total cholesterol(TC), alanine transaminase(ALT), and aspartate transaminase(AST) in the serum were determined by the biochemical method. The levels of TG and TC in the liver were measured by the enzyme method. Oil-red O staining was employed to detect the lipid accumulation, and hematoxylin-eosin(HE) staining to detect the pathological changes in the liver tissue. The mRNA and protein levels of mTOR, SREBP-1c, HSP60, MCAD, and SCAD in the liver tissue of rats were determined by real-time fluorescence quantitative polymerase chain reaction(RT-qPCR) and Western blot, respectively. Compared with the control group, the model group showed increased body weight, food uptake, liver index, TG, TC, ALT, and AST levels in the serum, TG and TC levels in the liver, lipid deposition in the liver, obvious hepatic steatosis, up-regulated mRNA and protein expression levels of mTOR and SREBP-1c, and down-regulated mRNA and protein expression levels of HSP60, MCAD, and SCAD. Compared with the model group, the rats in each treatment group showed obviously decreased body weight, food uptake, liver index, TG, TC, ALT, and AST levels in the serum, TG and TC levels in the liver, lessened lipid deposition in the liver, ameliorated hepatic steatosis, down-regulated mRNA and protein le-vels of mTOR and SREBP-1c, and up-regulated mRNA and protein levels of HSP60, MCAD, and SCAD. The high-dose diosgenin outperformed the low-dose diosgenin and simvastatin. Diosgenin may prevent and treat NAFLD by inhibiting the expression of mTOR and SREBP-1c and promoting the expression of HSP60, MCAD, and SCAD to reduce lipid synthesis, improving mitochondrial function, and promoting fatty acid β oxidation in the liver.

Objective: To review the clinical characteristics, to illustrate diagnosis and management experience of orbital and cranial complications of pediatric acute rhinosinusitis. Methods: The clinical data of 24 children with orbital and cranial complications of acute rhinosinusitis who received endoscopic sinus surgery combined with drug treatment in Beijing Children's Hospital from January 2017 to December 2021 were retrospectively reviewed. There were 19 boys and 5 girls. The age varied from 13 to 159 months, with a median 47.5 months. The following diagnoses were obtained: 12 isolated subperiosteal orbital abscess, 2 associated with preseptal abscess, 2 associated with intraorbital abscess, 7 associated with optic neuritis, and 1 associated with septic cavernous sinus thrombosis. Clinical characteristics, organism isolated and outcomes were analyzed through descriptive methods. Results: All 24 patients presented with fever; 9 presented with nasal congestion and purulent discharge. The clinical manifestations of orbital infection included orbital edema, pain, proptosis and displacement of globe in all patients, while visual impairment was recognized in 7 children. Purulent drainage was cultured in 17 patients, among which 12 were positive. All patients underwent nasal endoscopic surgical interventions uneventfully, excluding one patient who required a second surgical procedure. Follow-up period ranged from 5 to 64 months. All patients resolved fully, with the exception of 2 children who got permanent blindness with visual loss preoperative. There was no recurrence or death. Conclusions: Orbital and cranial complications of pediatric acute rhinosinusitis could be severe with an occult onset. For patients with vison impairment, any signs of intracranial complications and a lack of response to conservative management, an urgent endoscopic intervention is needed.

Objective: To observe the effect of platelets on hematopoietic stem cell (HSCs) implantation in mice with radiation-induced bone marrow injury and bone marrow transplantation models. Methods: ①Male C57BL/6 mice were divided into a single irradiation group and a radiation infusion group after receiving (60)Co semimyeloablative irradiation for 18-10 weeks. The irradiation infusion group received 1×10(8) platelets expressing GFP fluorescent protein. ② The allogeneic bone marrow transplantation model was established. The experimental groups included the simple transplantation group (BMT) and the transplantation infusion group (BMT+PLT). The BMT group was infused through the tail vein only 5 × 10(6) bone marrow cells, the BMT+PLT group needs to be infused with bone marrow cells at the same time 1× 10(8) platelets. ③ Test indicators included peripheral blood cell and bone marrow cell counts, flow cytometry to detect the proportion of hematopoietic stem cell (HSC) and hematopoietic progenitor cells, bone marrow cell proliferation and apoptosis, and pathological observation of vascular niche damage and repair. Results: ①On the 3rd, 7th, 14(th), and 21st days after irradiation, the bone marrow cell count of the infusion group was higher than that in the single irradiation group (P<0.05), and the peripheral blood cell count was also higher. A statistically significant difference was found between the white blood cell count on the 21st day and the platelet count on the 7th day (P<0.05). In the observation cycle, the percentage of bone marrow cell proliferation in the infusion group was higher, while the percentage of apoptosis was lower. ② The results of bone tissue immunofluorescence after irradiation showed that the continuity of hematopoietic niche with red fluorescence was better in the irradiation infusion group. ③The chimerism percentage in the BMT+PLT group was always higher than that in the BMT group after transplantation.④ The BMT+PLT group had higher bone marrow cell count and percentage of bone marrow cell proliferation on the 7th and 28th day after transplantation than that in the BMT group, and the percentage of bone marrow cell apoptosis on the 14th day was lower than that in the BMT group (P<0.05). After the 14th day, the percentage of stem progenitor cells in the bone marrow cells of mice was higher than that in the BMT group (P<0.05). ⑤The immunohistochemical results of bone marrow tissue showed that the continuity of vascular endothelium in the BMT+PLT group was better than that in the BMT group. Conclusion: Platelet transfusion can alleviate the injury of vascular niche, promotes HSC homing, and is beneficial to hematopoietic reconstruction.

This study aimed to investigate the effects of exercise on prefrontal PGC-1α, Irisin, BDNF, oxidative stress, inflammation, and cognitive function in high-fat diet-induced obese mice, which may provide experimental evidence of exercise rehabilitation methods and target screening for obesity. Three-month-old male C57BL/ 6J wild-type mice were randomly divided into four groups: control, high-fat diet, high-fat diet with moderate intensity continuous training, and high-fat diet with high-intensity interval training group, with 10 mice in each group. The mice in the high-fat diet with moderate intensity continuous training group and the high-fat diet with high-intensity interval training group received 8 weeks of moderate-intensity continuous training or high-intensity interval training after 12-week high-fat feeding. Behavioral results showed that compared with the control group, reaction time of adhesive removal test was significantly increased (P<0. 01), and spontaneous alternation rate in Y-maze test and exploration time in the novel object recognition test were significantly decreased (P < 0. 01) in the high-fat diet group, indicating that high-fat diet led to cognitive dysfunction in mice. Results showed that compared with the control group, Nissl bodies dissolution and apoptosis were significantly increased (P<0. 01), levels of PGC-1α, Irisin, BDNF, IL-10, and T-SOD were significantly deceased (P<0. 05, P<0. 01), levels of IL-1β, TNF-α, NF-κB, cleaved Caspase-3, Bax/ Bcl-2, ROS, and MDA were significantly increased in the prefrontal lobe (P<0. 01), indicating that high-fat diet induced excessive inflammation, oxidative stress, and apoptosis, which were conducive to prefrontal lobe damage. Compared with the high-fat diet group, moderate intensity continuous or high-intensity interval training decresed reaction time of adhesive removal test (P<0. 01), increased spontaneous alternation rate of Y-maze test and exploration time of novel object recognition test (P<0. 05, P<0. 01), indicating that both continuous and interval training improved cognitive function in obese mice; meanwhile, Nissl bodies and levels of PGC-1α, Irisin, BDNF, IL-10, and T-SOD were significantly increased (P<0. 05, P<0. 01), and apoptosis and levels of IL-1β, TNF-α, NF-κB, cleaved Caspase-3, Bax/ Bcl-2, ROS, and MDA were significantly reduced in the prefrontal lobe (P<0. 01), indicating that both continuous and interval training alleviated obesity-induced inflammation, oxidative stress, and apoptosis in the prefrontal lobe. Both continuous and interval training significantly upregulated PGC-1α/ Irisin/ BDNF expression in the prefrontal lobe of obese mice, inhibited oxidative stress and inflammation, reduced apoptosis, and resulted in alleviating obesity-induced prefrontal lobe damage and cognitive dysfunction; morevover, interval training better than continuous.
ABSTRACT
Objective: To analyze the clinical characteristics and prognosis of primary and secondary pancreatic diffuse large B-cell lymphoma (DLBCL) . Methods: Clinical data of patients with pancreatic DLBCL admitted at Shanghai Rui Jin Hospital affiliated with Shanghai Jiao Tong University School of Medicine from April 2003 to June 2020 were analyzed. Gene mutation profiles were evaluated by targeted sequencing (55 lymphoma-related genes). Univariate and multivariate Cox regression models were used to evaluate the prognostic factors of overall survival (OS) and progression-free survival (PFS) . Results: Overall, 80 patients were included; 12 patients had primary pancreatic DLBCL (PPDLBCL), and 68 patients had secondary pancreatic DLBCL (SPDLBCL). Compared with those with PPDLBCL, patients with SPDLBCL had a higher number of affected extranodal sites (P<0.001) and had higher IPI scores (P=0.013). There was no significant difference in the OS (P=0.120) and PFS (P=0.067) between the two groups. Multivariate analysis indicated that IPI intermediate-high/high risk (P=0.025) and double expressor (DE) (P=0.017) were independent adverse prognostic factors of OS in patients with pancreatic DLBCL. IPI intermediate-high/high risk (P=0.021) was an independent adverse prognostic factor of PFS in patients with pancreatic DLBCL. Targeted sequencing of 29 patients showed that the mutation frequency of PIM1, SGK1, BTG2, FAS, MYC, and MYD88 in patients with pancreatic DLBCL were all >20%. PIM1 (P=0.006 for OS, P=0.032 for PFS) and MYD88 (P=0.001 for OS, P=0.017 for PFS) mutations were associated with poor OS and PFS in patients with SPDLBCL. Conclusion: There was no significant difference in the OS and PFS between patients with PPDLBCL and those with SPDLBCL. IPI intermediate-high/high risk and DE were adverse prognostic factors of pancreatic DLBCL. PIM1, SGK1, BTG2, FAS, MYC, and MYD88 were common mutations in pancreatic DLBCL. PIM1 and MYD88 mutations indicated worse prognosis.

Objective:To provide a basis for its diagnosis and treatment for clinicians by analyzing the clinical manifestations, imaging features and surgical efficacy of primary intraspinal paraganglioma.Methods:The clinical data of 6 patients with intraspinal paraganglioma from April 2014 to January 2021 in Xiangyang Central Hospital were retrospectively analyzed, and all patients were treated with microsurgery via a posterior median approach.Results:All 6 patients achieved total tumor resection, and the postoperative pathological diagnosis was paraganglioma. Among them, 1 patient′s tumor located inside and outside the cervical spinal canal without destruction of the vertebral body; 1 patient′s tumor located lumbosacral canal with destruction of the vertebral body; the others 4 patients′ tumor located within the lumbar spinal canal. The patients were followed up for 12 to 120 months after surgery, with a median follow-up time of 61.5 months. MRI examination was performed at the last follow-up, and no recurrence was observed. The patients underwent MRI examination at the last follow-up, and none of the patients recurred.Conclusions:The intraspinal paraganglioma is a rare tumor, and nonfunctional benign tumors are predominant. Its clinical and imaging manifestations lack specificity and are often difficult to diagnose before surgery. Surgical resection, especially complete resection, has a better prognosis, and the effectiveness of adjuvant therapy is uncertain.
ABSTRACT
We reported a rare case with metastatic prostate cancer complicated with hemorrhagic syndrome caused byprimary hyperfibrinolysis.The correct diagnosis of bleeding disorders is a prerequisite for choosing the correct treatment.Tranexamic acid can be used as the preferred treatment for patients with bleeding caused by primary hyperfibrinolysis. In this case, the combination of antifibrinolytics and antiandrogen therapy effectively controlled the severe bleeding symptoms caused by primary hyperfibrinolysis in metastatic prostate cancer. Appropriate treatment after early diagnosis is essential to prevent bleeding and improve prognosis.

ABSTRACT
Background and purpose:The Shanghai Municipal Center for Disease Control and Prevention provides annual updates on cancer occurrence and trends in Shanghai.This study aimed to investigate the cancer incidence and mortality in 201 7 and their trends from 2002 to 2017 in Shanghai. Methods:Data of new cancer diagnoses and deaths from 2002 to 2017 were obtained from the Shanghai Municipal Center for Disease Control and Prevention population-based cancer registry and Vital Statistics System.Cancer incidence and mortality stratified by year of diagnosis or death,gender and age group were analyzed.Number,proportion,crude rate,age-specific rate,age-standardized rate and others were calculated.The number,proportion and rates of common cancers in different groups were also calculated.Trends in age-standardized rate of incidence and death rates for all cancers combined and for the common cancer types by gender were estimated by joinpoint analysis and characterized by the annual percent change(APC)and average annual percent change(AAPC).Segi's 1960 world standard population was used for calculating age-standardized incidence and mortality. Results:The new cancer cases and deaths were 79 378 and 37 186 in Shanghai in 2017.The crude rate of incidence was 546.55/105,and the age-standardized rate was 246.31/105.The age-standardized rate of incidence was higher among females than among males.The crude rate of mortality was 256.04/1 05,and the age-standardized rate was 88.41/105.The age-standardized rate of mortality was higher among males than among females.The age-specific numbers and rates of incidence and mortality increased with age.The age-specific number and rate of incidence reached the peak at the age groups of 60-64 years and older than 85 years,and those of mortality among males reached the peak at the age groups of 60-64 years and older than 85 years,and those of mortality among females reached the peak at the age groups of older than 85 years,respectively.The sites of top 10 common cancer types sorted by the number of incidence cases among males were lung,colorectum,stomach,prostate,liver,thyroid,pancreas,bladder,kidney and oesophagus,and among females were lung,breast,thyroid,colorectum,stomach,pancreas,liver,brain,central nervous system(CNS),cervix uteri and gallbladder,the sites of those sorted by the number of deaths among males were lung,stomach,colorectum,liver,pancreas,prostate,oesophagus,bladder,lymphoma and gallbladder,among females were lung,colorectum,breast,stomach,pancreas,liver,gallbladder,brain,CNS,ovary and lymphoma.The top 10 common cancer types stratified by gender and the top 5 common cancer types stratified by common age groups merged of incidence and mortality had wide variations.Overall,the age-standardized rates of incidence were stable from 2002 to 2009,and increased 2.88%on average per year from 2009 to 201 7.The age-standardized rates of mortality were stable from 2002 to 2011,and decreased 2.66%on average per year from 2011 to 201 7.The trends differed by gender and cancer type. Conclusion:Lung cancer,colorectal cancer,pancreatic cancer,thyroid cancer,female breast cancer,cervical cancer and male prostate cancer are the most common cancers in Shanghai,the appropriate screening technical scheme should be formulated according to the current situation of malignant tumors in Shanghai,promote cancer opportunistic screening,promote appropriate technologies for intervention and management of cancer patients in the community,reduce the disease burden of malignant tumors.

Objective:To investigate the survival of cancer cases diagnosed during 2002-2013 in Shanghai. Methods:Data on new cancer cases with dead and follow-up information were obtained from the population-based cancer registry and vital statistics system of Shanghai Municipal Center for Disease Control and Prevention.Survival indicators stratified by year of diagnosis,gender,site and age were analyzed.Number of cases and proportion were calculated.The observed survival rates were calculated based on the life table.The probabilities of surviving from 0 to 99 years old were estimated according to the Elandt-Johnson model,and then the cumulative expected survival rates were calculated according to the Ederer Ⅱ method.Finally,the relative survival rates and average annual percent changes of their trends were calculated.The age-standardized relative survival rates adjusted by International Cancer Survival Standard weights were calculated. Results:Total 644 520 new cancer cases were diagnosed during 2002-2013 in Shanghai,accounting for 643 545(99.85%)cases included in the observed cohort for survival analysis.The 5-year observed survival rate increased from 37.61%to 46.47%.The 5-year relative survival rate increased from 42.1 8%to 51.11%.The 5-year age-standardized relative survival rate increased from 40.57%to 49.80%.Among the 5-year relative survival rates of cases diagnosed during 2011 to 2013,99.43%of thyroid cancer was the highest,followed by female breast cancer(88.35%)and corpus uteri cancer(85.56%);5.87%of pancreas cancer was the lowest,followed by gallbladder cancer(13.64%)and oesophagus cancer(17.72%).the rate of lung cancer with the largest number of cases was 23.59%,followed by colorectal cancer(59.82%)and stomach cancer(38.65%).The 5-year relative survival rate of total cases of all sites increased from 40.55%in 2002 to 52.77%in 2013,with an average annual percent change of 2.40%.13 cancer types showed increasing trends,such as liver cancer and lung cancer,while the trends of other cancer types were not statistically significant,such as pancreatic cancer and gallbladder cancer. Conclusion:The diagnostic levels and survival rates of cancer cases have been improved continuously in Shanghai.The trends of different cancer types were varied.
ABSTRACT
Objective:More than half of esophageal cancer incidences and deaths occurred in China.Based on the Shanghai Tumor Registration data,this study analyzed the incidence and mortality of esophageal cancer in Shanghai in 2016 and the changing trend from 2002 to 2016,in order to provide an epidemic basis for the prevention and treatment of esophageal cancer. Methods:Data on esophageal cancer in Shanghai from 2002 to 2016 were obtained through Shanghai Municipal Center for Disease Control and Prevention Population-based Cancer Registry and Vital Statistics System.The number of cases and deaths,crude rates,composition ratios,age-specific rates and cumulative rates were counted according to the year of diagnosis or death,gender and age groups.Segi's 1960 world standard population was used to calculate age-standardized rates of incidence and mortality,and corresponding truncated age-standardized rate(35-64 years old)on esophageal cancer.Z-test and Cochran test were used to compare the differences of age-specific rates and age-standardized rates among different subgroups,respectively.Temporal trend analyses were conducted by Joinpiont 4.9.1.0 software. Results:In 2016,the proportion of morphological verification of new cases of esophageal cancer in Shanghai was 73.1 8%,the proportion of death certificate only was 0.72%,and the ratio of death to incidence was 0.84.The number of new cases and deaths of esophageal cancer in Shanghai in 2016 were 1 398 and 1 171,accounting for 1.88%and 3.1 6%of all malignant tumors,respectively.The crude incidence and mortality of esophageal cancer were 9.65/100 000 and 8.09/100000,with age-standardized incidence and mortality of 3.36/100 000 and 2.67/100,000,respectively.The age-standardized incidence and mortality were significantly higher in males than in females.The age-specific incidence and mortality increased with age,and peaked at 50.54/100 000 and 53.35/1 00 000,respectively,among people aged 85 years and older.From 2002 to 2016,both the number of new cases and deaths of esophageal cancer in Shanghai showed a downward trend,and the age-standardized incidence and mortality also showed a downward trend,with an average annual deceleration of 4.45%[annual percent change(APC)=-4.45,P<0.001]and 4.1 7%(APC=-4.17,P<0.001),respectively. Conclusion:The incidence and mortality of esophageal cancer in Shanghai were at a low epidemic level across China,and showed a downward trend from 2002 to 2016.Esophageal cancer screening should focus on males and subjects aged 55 to 64 years.

Methods:The data of prostate cancer incidence and mortality in Shanghai from 2002-2016 were obtained from the Population-Based Cancer Registry and Vital Statistics of Shanghai Municipal Center for Disease Control and Prevention.The incidence,mortality,proportion,crude rate,age-specific rate and age standardized rate of prostate cancer were calculated.Age-standardized incidence and mortality were calculated using Segi's 1960 world standard population.Trends of prostate cancer incidence,mortality,age-standardized rate and age-specific rate were estimated by Joinpoint 4.9.1.0 software. Results:In 2016,there were 3 226 cases of newly diagnosed prostate cancer and 1 067 deaths in Shanghai,crude rate of incidence was 44.91/105,crude rate of mortality was 14.85/105,age-standardized incidence and mortality were 15.47/105 and 4.34/105.Age-specific incidence and mortality increased with age,and reached the highest level in the 80-84 year-old group and 85-year-old group.Urban incidence was higher than suburb in the 50-54 year-old group,75-79 year-old group,and 80-84 year-old group,with no statistical difference in mortality.Between 2002 and 2016,incidence and mortality increased gradually,the rise of age-standardized incidence slowed down after 2012,and the age-standardized mortality in urban area declined after 2012.The age-standardized incidence in suburb increased faster than that in urban area,and the incidence rate increased faster in the younger age groups. Conclusion:The incidence and mortality of prostate cancer in Shanghai were lower than the world level but higher than the national level,and the incidence increased gradually between 2002 and 2016.Incidence and mortality were higher in urban area than in suburb,but increased faster in suburb,and the incidence increased more rapidly in younger age groups,but the proportion of early stages at diagnosis was still low,suggesting that appropriate screening strategies should be considered.
ABSTRACT
Objective:To describe the epidemiological features and temporal trends of colorectal cancer in urban Shanghai from 1973 to 2017. Methods:Data on colorectal cancer in urban Shanghai was obtained through Shanghai Cancer Registry and Vital Statistics System.Joinpoint analysis was used to describe the temporal trends and annual percent change(APC)and age-period-cohort analysis was used to estimate the association between age,period and birth cohort and colorectal cancer. Results:A total of 105 847 cases and 60 447 deaths of colorectal cancer were diagnosed in urban Shanghai over the 45-year study period.Both the number of new cases and the number of deaths showed an increasing trend.In the same period,the age-standardized incidence of colorectal cancer in urban areas of Shanghai increased significantly from 14.1/100 000 in 1973 to 27.7/100 000 in 2017,while the age-standardized mortality rate increased from 8.2/100 000 to 10.7/100 000.The overall average annual age-standardized incidence and mortality rates were 20.4/100 000 and 11.0/100 000,respectively.With the increase of age,the age-standardized morbidity and mortality of colorectal cancer showed an obvious upward trend.Taking 1993-1997 as reference,the risk of colorectal cancer in Shanghai reached the highest in 2013-2017,and the corresponding relative risk was 1.2(95%confidence interval:1.2-1.3),while the lowest was 0.9(95%confidence interval:0.8-1.0)during 1973-1977.Mortality risk,on the contrary,decreased with the increase of time.Before 1953-1957,the risk of colorectal cancer in urban Shanghai increased with the increase of birth cohort time,and then showed a downward trend.There was a corresponding decline in the risk of colorectal cancer death among people born after 1957. Conclusion:The incidence and mortality of colorectal cancer in Shanghai showed an increasing trend from 1973 to 2017,but the prevalence trend of colorectal cancer is still different among different populations.
ABSTRACT
Complex ventral hernia refers to a large hernia that is complicated by a series of concurrent conditions. Change in intra-abdominal pressure is one of the main pathways through which various factors exert an impact on perioperative risk and postoperative recurrence. Taking abdominal pressure reconstruction as the core, the treatment strategy for complex abdominal hernia can be formulated from three aspects: improving patients' tolerance, expanding abdominal cavity volume, and reducing the volume of abdominal contents. Improving patients' tolerance includes abdominal wall compliance training and progressive preoperative pneumoperitoneum. To expand the volume of the abdominal cavity, implanting hernia repair materials, component separation technique, autologous tissue transplantation, component expend technique, and chemical component separation can be used. Initiative content reduction surgery and temporary abdominal closure may be performed to reduce the volume of abdominal contents. For different cases of complex ventral hernia, personalized treatment measures can be safely and feasibly adopted depending on the condition of the patients and the intra-abdominal pressure situation.

@#Abstract: Objective To investigate the differences in epidemiological and clinical characteristics of patients with spotted fever (SF) and severe fever with thrombocytopenia syndrome (SFTS). Methods A total of 86 patients with SF and 113 patients with SFTS who were laboratory-confirmed in the second-level and above hospitals in Lu'an City from January 2017 to January 2022 were selected. The basic data, epidemiological history, clinical data and laboratory test results of the two diseases were retrospectively analyzed for comparison. Results The proportion of male in SF group was 32.56% (28/86), and the proportion of male in SFTS group was 53.98% (61/113), the difference was statistically significant (χ2=9.067, P<0.01). The proportions of abdominal pain and diarrhea in the SF group were (3.49%, 3/83) and (21.24%, 24/113), which were significantly lower than corresponding (6.98%, 6/86) and (46.90%, 53/113) in the SFTS group (χ2=13.121, 37.322, P<0.01). The incidences of rash and eschar in SF group were 95.35% (82/86) and 20.93% (18/86), which were significantly higher than corresponding 1.77% (2/113) and 0.88% (1/113) in SFTS group (χ2=175.311, 22.721, P<0.01). The levels of leukocytes, platelets and C-reactive protein in the SF group were significantly higher than those in the SFTS group, and the levels of transaminase, lactate dehydrogenase and D-dimer were significantly lower than those in the SFTS group, and the differences were statistically significant (all P<0.05). Conclusions The rash and inflammatory reaction are more obvious in SF patients, while the liver function, myocardial function and coagulation function are significantly impaired in SFTS patients.
ABSTRACT
Type 2 diabetes mellitus(T2DM), a common chronic metabolic disease, is often accompanied by internal heat syndrome. Heat-clearing prescriptions are widely used to treat different heat syndromes of T2DM from the aspects of clearing stagnant heat, excess heat, damp heat, phlegm heat, and heat toxin, demonstrating remarkable effects. The mechanism of blood sugar-lowering agents has always been a hotspot of research. Recently, the basic studies of heat-clearing prescriptions from different perspectives have been increasing year by year. To clarify the mechanisms of heat-clearing prescriptions and find specific mechanisms, we systematically reviewed the basic studies of heat-clearing prescriptions commonly used for the treatment of T2DM in the past decade, intending to provide a reference for related research.

The present study aimed to investigate the effect of diosgenin on mammalian target of rapamycin(mTOR), fatty acid synthase(FASN), hypoxia inducible factor-1α(HIF-1α), and vascular endothelial growth factor A(VEGFA) expression in liver tissues of rats with non-alcoholic fatty liver disease(NAFLD) and explore the mechanism of diosgenin on lipogenesis and inflammation in NAFLD. Forty male SD rats were divided into a normal group(n=8) fed on the normal diet and an experimental group(n=32) fed on the high-fat diet(HFD) for the induction of the NAFLD model. After modeling, the rats in the experimental group were randomly divided into an HFD group, a low-dose diosgenin group(150 mg·kg~(-1)·d~(-1)), a high-dose diosgenin group(300 mg·kg~(-1)·d~(-1)), and a simvastatin group(4 mg·kg~(-1)·d~(-1)), with eight rats in each group. The drugs were continuously given by gavage for eight weeks. The levels of triglyceride(TG), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), alanine transaminase(ALT), and aspartate transaminase(AST) in the serum were detected by the biochemical method. The content of TG and TC in the liver was detected by the enzyme method. Enzyme-linked immunosorbent assay(ELISA) was used to measure interleukin 1β(IL-1β) and tumor necrosis factor α(TNF-α) in the serum. Lipid accumulation in the liver was detected by oil red O staining. Pathological changes of liver tissues were detected by hematoxylin-eosin(HE) staining. The mRNA and protein expression levels of mTOR, FASN, HIF-1α, and VEGFA in the liver of rats were detected by real-time fluorescence-based quantitative polymerase chain reaction(PCR) and Western blot, respectively. Compared with the normal group, the HFD group showed elevated body weight and levels of TG, TC, LDL-C, ALT, AST, IL-1β, and TNF-α(P<0.01), increased lipid accumulation in the liver(P<0.01), obvious liver steatosis, up-regulated mRNA expression levels of mTOR, FASN, HIF-1α, and VEGFA(P<0.01), and increased protein expression levels of p-mTOR, FASN, HIF-1α, and VEGFA(P<0.01). Compared with the HFD group, the groups with drug treatment showed lowered body weight and levels of TG, TC, LDL-C, ALT, AST, IL-1β, and TNF-α(P<0.05, P<0.01), reduced lipid accumulation in the liver(P<0.01), improved liver steatosis, decreased mRNA expression levels of mTOR, FASN, HIF-1α, and VEGFA(P<0.05, P<0.01), and declining protein expression levels of p-mTOR, FASN, HIF-1α, and VEGFA(P<0.01). The therapeutic effect of the high-dose diosgenin group was superior to that of the low-dose diosgenin group and the simvastatin group. Diosgenin may reduce liver lipid synthesis and inflammation and potentiate by down-regulating the mTOR, FASN, HIF-1α, and VEGFA expression, playing an active role in preventing and treating NAFLD.

【Objective】 To determine the volume range of suspended erythrocyte and establish its internal control standard. 【Methods】 The theoretical value of suspended erythrocyte volume was calculated according to the screening criteria of healthy blood donors and Quality Requirements for Whole Blood and Blood Components. A total of 2 410 bags of 1 U and 2 U suspended erythrocyte were randomly selected and weighed, and the volume range were formulated by ±2S and ±10% respectively and then compared to determine the volume range in line with the actual situation of our center. 【Results】 The theoretical volume range of 1 U and 2 U suspended erythrocyte were 117-160 mL vs 234-320 mL, and the actual volume range were 142-180 mL vs 276-393 mL. The volume range of 1 U and 2 U suspended erythrocyte formulated by ±2S were 145-181 mL vs 298-358 mL, and by ±10% were 147-179 mL vs 295-361 mL. The hematocrit and hemoglobin content of suspended erythrocyte within the actual volume range met the quality requirements. There were fluctuations in the volume of suspended erythrocyte from different regions. 【Conclusion】 Based on the actual situation of our center and the sampling results of suspended erythrocytes in recent two years, 163 mL±10% and 328 mL±10% were determined as the internal control standards of 1 U and 2 U suspended erythrocyte, respectively. Blood centers should establish accurate and feasible standard of suspended erythrocyte according to the actual situation.
