Objective To study the prognostic factors of primary duodenal papilla carcinoma.Methods The clinical data of 73 patients with primary duodenal papilla carcinoma who were admitted to the Dongnan Hospital of Xiamen University from June 1995 to June 2005 were retrospectively analyzed.Ten factors including gender,age,jaundice,tumor size,course of disease,total bilirubin,tumor differentiation,lymphatic metastasis,type of surgery and degree of resection were analyzed by Log-rank test.Prognostic factors with significant difference were further analyzed by the Cox regression model.The survival curve was drawn by using the Kaplan-Meier method.Results The median survival time of the patients was 34 months.Age,jaundice,tumor size,course of disease,total bilirubin,tumor differentiation,lymphatic metastasis,type of surgery and degree of resection were correlated with the prognosis (x2 =18.315,4.562,7.989,10.660,11.138,7.995,5.423,114.464,83.383,P＜0.05),while no significant difference was found between gender and prognosis ( x2 =1.720,P ＞ 0.05 ).Multivariate analysis demonstrated that tumor differentiation,type of surgery and degree of resection were the factors influencing the prognosis of patients with duodenal papilla carcinoma (RR =2.039,2.178,5.798,P＜0.05).Conclusions Tumor differentiation,type of surgery and degree of resection are the dependent factors influencing the prognosis of patients with duodenal papilla carcinoma.The standard type of surgery and degree of resection are important for the prognosis of patients.

Objective To investigate the prevalence of diabetic foot(DF) in the hospitalized diabetic patients and analyze the clinical characteristics and therapeutic efficacy of patients with diabetic foot. Methods The 313 patients (180 males and 133 females) were divided into two groups：group A (1/1996-12/2003) and group B (1/2004-12/2006). Results 2.79% of the hospitalized diabetic patients had diabetic foot. The mean age and duration of diabetes were 66±10 years old and 9.33±6.52 years respectively, the mean duration of diabetic foot was 8.13±17.06 months and the average days in hospital was 29.62±28.36d. Many patients suffered from diabetic nephropathy, cataracts, retinopathy, neuropathy, vascular disease, hypertension, infection, and so on. The blood pressure and blood glucose were poorly controlled in many of the patients. Of all patients, 28.1% were completely healed, 40.6% were improved without amputation and 31.3% had not healed at the time of death or follow-up (including 9.3 % of them were amputated in leg and 6.2% were dead). But group B versus group A showed higher cure rates of DF (37.04 % vs 18.54 %). Conclusions The prevalence of DF in the hospitalized diabetic patients is gradually increased, most patients with DF accompany with one or multiple other complications. A multifactorial treatment by a multidisciplinary foot care team is a superior treatment strategy for improving prognosis of patients with DF.

Abstract: Objective To summarize the clinical characteristics of 35 patients with human monkeypox in Chengdu City, in order to provide theoretical basis for prevention and control of monkeypox epidemic in China. Methods A total of 35 patients diagnosed with monkeypox infection by Chengdu CDC from July 1 to July 23, 2023 were included in our study. The results of general clinical data, blood laboratory tests, lymph node ultrasound and chest CT results were collected in order to analyze the clinical features of human monkeypox patients in Chengdu City. Results All 35 monkeypox patients were young adult males, and there were no serious or fatal cases. Among them, 32 cases (91.4%) were men who have sex with men (MSM), and 30 cases had engaged in male-to-male sexual behavior within 21 days prior to the onset of the disease, of which 13 cases had taken protective measures. Fever symptoms were observed in 26 cases (74.3%) of the patients, with 19 cases experiencing fever within 1-6 days after the appearance of rash. The initial rash commonly occurred in the male external genitalia. Color ultrasound examinations indicated that all patients had swollen inguinal lymph nodes. C-reactive protein was elevated in 26 cases (74.3%) of patients, and 19 cases showed CD3+CD4+T/CD3+CD8+T< 1.0. 15 cases (42.8%) of the patients were infected with both monkeypox virus and HIV, 28.5% (10/35) of patients had concomitant skin infections and anorectal proctitis,respectively. The mean time from rash onset to the shedding of rash scabs was 14.8 days. Conclusions The MSM population in sexually active age group is the main infection object of human monkeypox virus. In monkeypox patients in Chengdu City, the rash starting at genital areas and rash occurring before systemic symptoms were common. Swollen inguinal lymph nodes are especially common in monkeypox patients. Skin infection and anorectal proctitis are the most common complications in monkeypox patients in Chengdu City. The abnormal cellular immune function in monkeypox patients is mainly reflected in the inverted ratio of CD3+CD4+T/CD3+CD8+T. Currently, there is no evidence to suggest that protective measures during male-to-male sexual behavior can reduce the risk of human monkeypox infection.

Objective:To understand the attitudes and cognition of disease control and prevention professionals at provincial level on public health physician standardized training and provide evidence for the improvement of the standardized training and exploration of more effective training mode in China.Methods:By cluster sampling, 2 193 professionals at provincial centers for disease control and prevention (CDC) in 6 provinces, including Jiangsu and Guangdong, Shanxi and Hubei,Sichuan and Xinjiang were selected as the study subjects, the sample size was estimated to be 1 933 persons.Results:A total of 1 716 provincial-level CDC professionals were surveyed, the support rate to the standardized training was 70.7%(1 213/1 716). The level of support was negatively associated with the educational level of professionals and their specialty of public health and preventive medicine. Of 875 public health and preventive medicine professionals, 61.6%(318/516) of those with master's degree or above supported the standard training for public health physicians, which was lower than 73.1%(225/308) of those with bachelor's degree and 86.3%(44/51) of those with college degree or below. There were 14.9%(232/1 555) of the respondents suggested a two year training, and 60.4%(933/1 544) suggesting a field training mode. In terms of training content, 86.6%(1 355/1 564) suggesting "epidemiological survey and public health practice", and 76.7%(1 199/1 564) suggesting "basic theories and methodology".Conclusions:In general, the professionals of provincial CDC showed a relatively low interest in the standardized training for public health physicians and failed to reach a consensus. Besides, they were ill-informed about current training duration, method and content. Thas, the professionals at provincial CDC are suggested to be the key target-population whom should be mobilized during the training pilot period, especially the highly educated ones with relevant specialties of public health. It is suggested that public health physician standardized training should to be implemented in whole CDC system to reach full consensus based on its practical achievements and effects. It is also suggested to establish public health graduate medical education system in China.

Objective To evaluate the efficacy of XELOX regimen as neoadjuvant chemotherapy in the treatment of stage Ⅱ and Ⅲ colon cancer.Methods The clinical data of 50 patients with clinical stage Ⅱ(T4)Ⅲ colon cancer who underwent laparoscopic radical resection at general surgery department of our hospital from January 1,2012 to January 1,2021 were retrospectively analyzed.Patients were divided into neoadjuvant chemotherapy group(NACT)and adjuvant chemotherapy group(ACT)according to whether they received neoadjuvant chemotherapy with XELOX regimen.The general clinical data,adverse reactions of chemotherapy,surgical complications,operation time,intraoperative blood loss,hospitalization time,hospitalization cost,negative conversion rate of tumor markers,tumor remission rate,tumor downstaging rate,tumor response grade after chemotherapy,postoperative disease-free survival curve,and overall survival curve were retrospectively analyzed and compared among the groups.Results There were no significant differences in operative complications,postoperative exhaust time and hospital stay between NACT group and ACT group(P＞0.05).The adverse reactions of chemotherapy,the negative conversion rate of postoperative CEA and CA19-9,the duration of operation,the amount of bleeding,and the hospitalization cost in NACT group were significantly better than those in ACT group(P＜0.05).In terms of DFS and OS survival curves,with the extension of time,the decline of the NACT survival curve was smaller than that of the ACT group,and there was a significant difference in DFS survival curve(P＜0.05),but no significant difference in OS survival curve(P＞0.05).Conclusion XELOX neoadjuvant chemotherapy is safe and effective in the treatment of stage Ⅱ(T4)and stage Ⅲcolon cancer.

Objective To investigate the clinical significance of complement activation in patients with HBV related glomerulonephritis (HBV-GN).Methods Biopsy-proven HBV-GN patients admitted in our hospital were retrospectively recruited.Decreased serum C3 level was defined as C3 ＜ 85 mg/dL.According to the serum C3 level,the patients were divided into the decreased serum C3 group and normal serum C3 group,and the pathological and clinical differences were compared between the two groups.According to the intensity of C3 deposition in the kidney,patients were divided into negative and positive group,and the pathological and clinical differences were compared.Results In this study,29 HBV-GN patients were recruited.There were 18 (62.07％) patients in the normal serum C3 group and 11 (37.93％) patients in the decreased serum C3 group.Compared with the patients with normal serum C3 level,patients with decreased serum C3 level had higher serum creatinine level,lower eGFR level,severer mesangial proliferation and renal interstitial fibrosis (P ＜ 0.05).There were 9 (31.03 ％) patients with negative C3 deposition in the kidney,and 20 (68.97％) patients with positive C3 deposition.Higher cholesterol,higher IgG levels,lower serum albumin,serum C 3 levels,lower eGFR level,severer glomerular sclerosis,inflammatory cell infiltration in renal interstitial,renal tubular atrophy,and renal interstitial fibrosis were associated with a higher grade of C3 deposition in the kidney (P ＜ 0.05).Conclusion There are different levels of complement activation in patients with HBV-GN.Local and systemic complement activation is associated with decreased renal function.Complement activation may be involved in the development of HBV-GN.

OBJECTIVE: To explore the potential association between occupational medicamentosa-like dermatitis induced by trichloroethylene( OMDT) and past infection,reactivation and recent infection of human herpesvirus 6( HHV6) and human cytomegalovirus( HCMV). METHODS: Twenty OMDT patients were recruited as case group by using judgment sampling method. Twenty healthy workers occupationally exposed to trichloroethylene for more than half a year were randomly selected as exposure group. Twenty healthy people with no exposure history to trichloroethylene were randomly selected as control group. The enzyme linked immunosorbent assay was used to qualitatively determine the titer of HHV6 and HCMV immunoglobulin( Ig) G,Ig M antibodies from serum samples of these subjects. The polymerase chain reaction was used to qualitatively detect HHV6 and HCMV DNA from whole blood DNA samples of these subjects. The differences of previous infection rate,reactivation rate and recent infection rate of HHV6 and HCMV among these three groups of patients with different clinical types of OMDT were analyzed. RESULTS: The prevalence of HHV6 and HCMV infection in the case group was higher than that in the control group,and the difference was statistically significant( 65. 5% vs 20. 0%,75. 0% vs15. 0%,P < 0. 017). The reactivation rate of HHV6 and HCMV in the case group was higher than that in the control group,but the difference was not statistically significant( P > 0. 017). The recent infection rate of HHV6 and HCMV in the case group was not significantly different from that in the control group( P > 0. 017). There was no significant difference in the past infection rate,reactivation rate and recent infection rate of HHV6 and HCMV between the exposure group and the control group( P > 0. 05),meanwhile in different clinical types of OMDT patients( P > 0. 05). CONCLUSION: OMDT may be associated with past infection of HHV6 and HCMV.

Objective:To compare the efficacy of transcatheter arterial embolization (TAE) with laparotomy in the treatment of severe liver injury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 48 patients with severe liver injury admitted to 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from December 2013 to June 2020, including 28 males and 20 females; aged 16-75 years [(45.7±6.2)years]. There were 25 patients with grade III, 15 grade IV and 8 grade V according to the American Association for the Surgery of Trauma (AAST) classification. After general treatments such as infusion and hemostasis, TAE was performed in 26 patients (TAE group) and laparotomy in 22 patients (laparotomy group). The operation time and length of hospital stay were compared between the two groups. Erythrocyte, hemoglobin and serum creatinine were compared before operation and at postoperative 1 day. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were analyzed before operation and at postoperative 1, 3, 7 days. Complications were observed.Results:All patients were followed up for 12-60 months [(17.1±9.1)months]. The operation time and length of hospital stay were (65.7±9.2)minutes and (21.6±6.6)days in TAE group, significantly shorter than (162.5±28.1)minutes and (31.5±7.4)days in laparotomy group ( P<0.05 or 0.01). There was no significant difference between the two groups referring to erythrocyte, hemoglobin and serum creatinine before operation and at postoperative 1 day (all P>0.05). There was no significant difference in ALT and AST between the two groups before operation (all P>0.05). TAE group showed ALT level of 1 154(884, 1 698)U/L, (975.3±400.9)U/L and (403.4±232.9)U/L at postoperative 1, 3, 7 days, significantly lower than 2 053(1 965, 2 132)U/L, (1 604.1±188.2)U/L and (915.3±160.5)U/L in laparotomy group (all P<0.05). TAE group showed AST level of (1 313.2±542.0)U/L, 525(302, 971)U/L and 174(84, 324)U/L at postoperative 1, 3, 7 days, significantly lower than (1 962.9±245.4)U/L, 1 478(1 089, 1 677)U/L and 837(674, 1 006)U/L in laparotomy group ( P<0.05 or 0.01). The complication rate was 26.9% (7/26) in TAE group, significantly lower than 59.1% (13/22) in laparotomy group ( P<0.05). Conclusion:For severe liver injury, TAE can significantly shorten operation time and length of hospital stay, accelerate the recovery of liver function and reduce the complication rate in comparison with laparotomy.
