Objective:To explore the team construction and treatment strategy of the Diabetic Foot-Multidisciplinary Team.Methods:The clinical data of 19 patients with severe ischemic diabetic foot treated by our Diabetic Foot-Multidisciplinary Team Center from Apr 2021 to Mar 2022 were collected, and the overall amputation rate, above-ankle major amputation rate, minor amputation rate and mortality, Diabetic Foot-Multidisciplinary Team consultation discipline participation rate and treatment participation degree were retrospectively analyzed.Results:Nineteen patients (15 males and 4 females) were enrolled, aged 26 to 94 (68.6±14.2). All were with severe ischemic diabetic foot ulcer:Rutherford grade 5 or up and dysfunction in 2 or more organs. Complications included arteriosclerosis obliterans of the lower extremities in 18 cases, heart diseases in 18, hypertension in 15, and renal insufficiencies in 10. The overall amputation rate was 36.8%, major amputation rate in 21.1%, minor amputation rate in 15.8%, and mortality rate was 15.8%. A total of 16 disciplines participated in Diabetic Foot-Multidisciplinary Team; the main participating disciplines were vascular surgery (19 times), endocrinology (12 times), and cardiology (11 times). The main treatment disciplines were vascular surgery (14 times), plastic surgery (3 times), and cardiology (2 times).Conclusion:For the diagnosis and treatment of diabetic foot, it is necessary to set up a multidisciplinary team as early as possible to control the causes of diabetic foot ulcer, prevent the recurrence of diabetic foot ulcer, reduce the mortality and amputation rate, and improve the quality of life of patients.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

CD4 and CD8 T cells are key players in the immune response against both pathogenic infections and cancer. CD4 T cells provide help to CD8 T cells via multiple mechanisms, including licensing dendritic cells (DCs), co-stimulation, and cytokine production. During acute infection and vaccination, CD4 T cell help is important for the development of CD8 T cell memory. However, during chronic viral infection and cancer, CD4 helper T cells are critical for the sustained effector CD8 T cell response, through a variety of mechanisms. In this review, we focus on T cell responses in conditions of chronic Ag stimulation, such as chronic viral infection and cancer. In particular, we address the significant role of CD4 T cell help in promoting effector CD8 T cell responses, emerging techniques that can be utilized to further our understanding of how these interactions may take place in the context of tertiary lymphoid structures, and how this key information can be harnessed for therapeutic utility against cancer.

Objective:To investigate the psychology status and quality of life in patients with inflammatory bowel disease(IBD) in China, and to analyze the influencing factors.Methods:From September 2021 to May 2022, 42 hospitals in 22 provinces(autonomous regions and municipalities directly under the central government) in China, the clinical data of 2 478 IBD patients were collected, which included age, gender, weight, first visit or not, disease activity, disease course, main clinical manifestations(diarrhea, abdominal pain, hematochezia, extraintestinal manifestations), complications, treatment medication(5-aminosalicylic acid, glucocorticoids, immunosuppressive agents, and biological agents), and whether to have surgery. Anxiety, depression, sleep quality and quality of life of IBD patients were evaluated by generalized anxiety disorder-7 items, patient health questionnaire-9 items, Pittsburgh sleep quality index and inflammatory bowel disease questionnaire, and the related influencing factors were analyzed. Univariate analysis and multiple linear regression analysis were used for statistical analysis.Results:The average age of 2 478 IBD patients was 37.96 years old, and male counted for 62.43%(1 547/2 478). There were 61.82%(1 532/2 478) of the IBD patients in the active stage of disease, mostly mild or moderate(588 and 734 cases). There were 60.61%(1 502/2 478) of the IBD patients with different degrees of anxiety, 58.35%(1 446/2 478) of the IBD patients with different degrees of depression, and 48.87%(1 211/2 478) of the IBD patients had different degrees of sleep problems. The results of multiple linear regression analysis indicated that female, higher level of disease activity and longer disease course were independent risk factors of anxiety, depression and sleep quality in the IBD patients(unstandardized regression coefficient(95% confidence interval) 1.08(0.65 to 1.50), 0.45(0.23 to 0.68), 0.19(0.02 to 0.36), 0.83(0.33 to 1.32), 0.62(0.36 to 0.88), 0.28(0.08 to 0.47), 0.47(0.16 to 0.77), 0.39(0.23 to 0.55), 0.14(0.02 to 0.26); P<0.001, <0.001, =0.025 , =0.001, <0.001, =0.005, =0.003, <0.001, =0.027). The usage of biological agents was an independent protective factor of anxiety(unstandardized regression coefficient(95% confidence interval) -0.67(-1.17 to -0.17), P=0.008), and older age was an independent risk factor of sleep quality(unstandardized regression coefficient(95% confidence interval) 0.35(0.09 to 0.61), P=0.008). Higher level of disease activity, symptoms of diarrhea, abdominal pain, presence of extraintestinal manifestations, usage of 5-aminosalicylic acid and glucocorticoid, and with surgical treatment were independent risk factors of quality of life(unstandardized regression coefficient(95% confidence interval) -11.00(-12.24 to -9.76), -2.90(-5.26 to -0.55), -3.93(-6.25 to -1.61), -5.79(-9.87 to -1.71), -4.78(-7.79 to -1.76), -7.71(-11.07 to -4.35), -4.37(-8.00 to -0.73); P<0.001, =0.016, =0.001, =0.005 , =0.002, <0.001, =0.019), while the usage of biological agents was an independent protective factor of quality of life (unstandardized regression coefficient(95% confidence interval) 4.72(1.97 to 7.48), P=0.001). Conclusion:IBD patients generally have different degrees of anxiety, depression and sleep problems, which affect the quality of life of patients. Gender, disease activity and disease course are the influencing factors of mental disorders in IBD patients.

Objective:To evaluate the effect of oral nutritional supplementation (ONS) on the nutritional status and quality of life in patients with colorectal cancer and postoperative adjuvant chemotherapy.Methods:This study was registered in the Chinese Clinical Trial Registry (ChiCTR-TRC-13003798). A multi-center randomized controlled trial was conducted. Colorectal cancer patients who underwent radical surgery and postoperative adjuvant chemotherapy, and had nutritional risk (nutrition risk screening 2002 score ≥3) when discharge from hospital in six hospitals (Beijing Hospital, Peking University Third Hospital, Guangzhou Nanfang Hospital, Shanghai Xinhua Hospital, Shanghai Ruijin Hospital, and Shanghai The Sixth People's Hospital) from June 2013 to August 2015 were prospectively enrolled. These patients were randomly divided into the ONS group and control group. Patients in the ONS group received dietary guidance and oral nutritional supplements (2092 kJ/day, whole protein enteral nutrition) for 90 days after discharge from hospital, while patients in the control group only received dietary guidance. Anthropometric measurements (body weight, body mass index [BMI], upper arm circumference, gripping power of the dominant hand, triceps skin fold), nutrition-related laboratory tests (hemoglobin, albumin, prealbumin, total cholesterol, triglyceride), gastrointestinal function scores and quality of life (evaluated by EuroQol five dimensions questionnaire) were collected and compared at baseline (at discharge), and at 30-day, 60-day and 90-day after discharge.Results:A total of 90 patients were included into this multi-center study, of whom 5 patients dropped out, 43 patients were assigned to the ONS group and 42 patients to the control group. Compared with baseline, the body weight of patients in the ONS group increased by (1.523±0.525) kg at 60-day and (1.967±0.661) kg at 90-day, which were significantly higher than those of patients in the control group [60-day: (-0.325±0.518) kg, P=0.015; 90-day: (-0.224±0.705) kg, P=0.027, respectively]. A similar pattern was observed for BMI, the ONS group increased by (0.552±0.203) kg/m 2 at 60-day and (0.765±0.205) kg/m 2 at 90-day, which were significantly higher than those of patients in control group [60-day: (-0.067±0.202) kg/m 2, P=0.034; 90-day: (0.022±0.210) kg/m 2, P=0.013]. No significant differences of other anthropometric measurements and nutrition-related laboratory tests were found between the two groups (all P>0.05). Furthermore, there were no significant differences of improvement in gastrointestinal function and quality of life between two groups (all P>0.05). Conclusion:Oral nutritional supplements can improve the body weight and BMI of colorectal cancer patients with nutritional risk receiving postoperative adjuvant chemotherapy, though it does not improve the quality of life.

Objective:To compare the efficacy and safety of triamcinolone acetonide (TA) alone and in combination with 5-fluorouracil (5-FU) for treating keloids using meta-analysis.Methods:Databases including PubMed, Embase, and Cochrane Library were retrieved with the search terms of " triamcinolone acetonide, 5-fluorouracil, glucocorticoid, fluorouracil, keloid, scar, TAC, 5-FU, hypertrophic scar " and databases including Chinese Journal Full- Text Database, Chinese Biomedical Database, and Wanfang Data were retrieved with the search terms of "曲安奈德,瘢痕疙瘩, 5-氟尿嘧啶,糖皮质激素,增生性瘢痕" in Chinese to obtain the publicly published randomized controlled trials about the effects of TA alone and in combination with 5-fluorouracil for treating keloids from the establishment of each database to august 2019. The outcome indexes included effective proportion of treatment, incidence proportion of adverse reactions, and recurrence proportion of keloids. RevMan 5.3 and Stata 14.0 statistical software were used to conduct a meta-analysis of eligible studies. Results:A total of 1 326 patients with keloids were included in 14 studies, including 668 patients in TA+ 5-fluorouracil group whose keloids were injected with TA and 5-fluorouracil and 658 patients in TA alone group whose keloids were injected with TA alone. A total of 7 articles achieved 1 to 3 points in modified Jadad score, while 7 articles achieved 4 to 7 points in modified Jadad score. Patients in TA+ 5-fluorouracil group had a higher effective proportion of treatment than that of TA alone group (relative risk=1.28, 95% confidence interval=1.16-1.41, P<0.01). Subgroup analysis showed that the quality of the included literature and ethnic factors might be the source of heterogeneity in effective proportion of treatment. Patients in TA+ 5-fluorouracil group had a lower incidence proportion of adverse reactions than that of TA alone group (relative risk=0.44, 95% confidence interval=0.25-0.75, P<0.01). Patients in TA+ 5-fluorouracil group had a lower recurrence proportion of keloids than that of TA alone group (relative risk=0.25, 95% confidence interval=0.14-0.44, P<0.01). There was no publication bias in incidence proportion of adverse reactions ( P>0.05), while the effective proportion of treatment and recurrence proportion of keloids had publication bias ( P<0.05). Conclusions:TA combined with 5-fluorouracil is more effective than TA alone for treating keloids, with less incidence of adverse reactions and recurrence.

Objective: To investigate whether elevated levels of C-reactive protein (CRP) and neutrophil (NE) in the blood is associated with an increased risk of lung cancer incidence. Methods: From 2006 to 2007, all employees and retirees from Kailuan (Group) Limited liability Corporation were included in this Kailuan Cohort study. The last follow-up date was December 2015. Data on new cases of lung cancer were collected, and multivariable Cox proportional hazards regression models were used to the relationship between baseline CRP and NE at baseline and risk of lung cancer. Results: A total of 92 735 participants were enrolled in this study. During the follow-up, 850 new cases of lung cancer were identified. All subjects were divided into four groups according to the combination level of CRP and NE at baseline: CRP≤3 mg/L and NE≤4×10⁹/L(Group A), CRP≤3 mg/L and NE>4×10⁹/L(Group B), CRP>3 mg/L and NE≤4×10⁹/L(Group C), CRP>3 mg/L and NE>4×10⁹/L(Group D). The cumulative incidence of lung cancer were 950/100 000, 1 030/100 000, 1 081/100 000 and 1 596/100 000 in these four groups, respectively (P<0.001). Multivariate Cox proportional risk model showed that participants from Group D had an significantly increased 72% risks of lung cancer when compared to Group A (95% CI: 1.40~2.12, P<0.001). Stratified analyses gender showed that males in Group D had higher risk of lung cancer when compared with participants in Group A (HR=1.73, 95% CI: 1.40~2.15, P<0.001). Conclusion Elevated levels of CRP and NE might increase the risk of lung cancer.
