Renal metastasis from differentiated thyroid cancer (DTC) is uncommon and is hard to be distinguished from primary renal cell carcinoma. There is no consensus on diagnosis and treatment, and decisions about surgery and 131I therapy doses usually depend on experience. To better understand clinical characteristics and current treatment status, this study systematically reviews existing studies, exploring epidemiological features, clinical symptoms, imaging findings (including lesions characteristics across various imaging modalities), therapeutic strategies, and prognosis of DTC renal metastases, providing evidence-based references for clinical practice.

Purpose: Seroma formation is a common complication in breast cancer patients undergoing mastectomy, and it negatively affects patient recovery after surgery. The present study aimed to evaluate a simple method using fascia suture technique to fix the flap and reduce the incidence of seroma. Methods: A single-center, prospective, randomized controlled trial was carried out among 160 patients who had undergone mastectomy from May 2018 to September 2019. All patients were randomly divided into the fascia suture group (n = 80) or control group (n = 80) and were followed up for at least 3 months for the assessment of immediate and late complications after surgery. Results: No significant differences were observed between the 2 groups with regard to the basic characteristics. Duration of surgery in the fascia suture group was longer by about 6 minutes compared with that in the control group (114.93 ± 13.67 minutes vs. 108.81 ± 15.20 minutes, p = 0.008). The fascia suture group had a shorter duration of drain placement (10.99 ± 3.26 days vs. 13.85 ± 5.37 days, p < 0.001), a smaller volume of the total drainage (460.95 ± 242.92 mL vs. 574.83 ± 285.23 mL, p = 0.007), and the first 3-day drainage (224.96 ± 101.01 mL vs. 272.3 ± 115.47 mL, p = 0.006), compared with the control group. The incidence of seroma formation (G2 or G3) was significantly lower in the fascia suture group compared with the control group (28.8% vs. 12.5%, p = 0.033). Besides, there was no statistical difference between the 2 groups in the assessment of other complications, including postoperative pain, hematoma, surgical site infections, flap necrosis, and skin dimpling (all p > 0.050). Conclusion The fascia suture technique is a simple and effective method for reducing seroma formation and should be used to prevent seroma formation after mastectomy.

Objective:To investigate the effects of laparoscopy assisted complete mesocolon resection on the stress response and immune function of patients with colon cancer.Methods:From January 2013 to January 2016,130 patients with colon cancer in our hospital were selected and randomly divided into the observation group and the control group with 65 cases in each group according to the random lottery envelopes.The observation group was treated with laparoscopy assisted complete mesocolon resection,the control group was treated with open operation.The changes of semm IL-6,TNF-α and amours of CD4+ cells,blood loss,bowel function restoration time,hospital stays and complication rate of two groups were compared before and after treatment.Results:Both groups of patients were successfully completed the surgery and there was no serious complications occurred in both groups.The amount of bleeding,postoperative intestinal recovery time and postoperative hospital stay in the observation group were significantly less than those of the control group (P＜0.05).The chylous fistula,wound infection,pulmonary infection and complication rate on the 14th day postoperation in the observation group was 1.5％,which was 12.3％ in the control group and significantly higher than that of the control group (P＜0.05).The contents ofCD4+ cells in the observation group and the control group were 36.34± 7.83％ and 33.66± 9.82％,respectively,which were significantly higher than those before treatment(30.33± 6.49％ and 30.49± 5.33％)(P＜0.05),and the contents of CD4+ cells of observation group was significantly higher than that of the control group after treatment (P＜0.05).The serum levels ofIL-6 and TNF-α in both groups were significantly lower than those before treatment on the 14th day postoperation (P＜0.05),and the serum IL-6 and TNF-α levels of observation group were significantly lower than those in the control group on the 14th day postoperation (P＜0.05).Conclusion:Laparoscopy assisted complete mesocolon resection could promote the immune function and inhibit the stress response,which further promoted the rehabilitation and induced the complications in the treatment of patients with colon cancer.

OBJECTIVETo evaluate the efficacy and safety of Reduning injection for treating community-acquired pneumonia.

METHODLiteratures about randomized controlled trials of Reduning injection for treating community-acquired pneumonia were reviewed. The methodological quality of the trials was assessed by the Jadad scale, and evaluation was performed.

RESULTSeven RCTS were included. Reduning combined group (Reduning injection plus antibiotics and basic therapy) was compared with antibiotics group (antibiotics plus basic therapy). Meta-analysis showed that the relative risk (RR) for the total cure rate was 1.34, and 95% confidence interval (CI) was [1.19, 1.51]; RR for the total effective rate was 1.10, and 95% CI was [1.06, 1.15]. The weighted mean difference (WMD) in disappearance time of fever between the two groups was - 1.42, and 95% CI was [- 2.58, -0.26]; The WMD between the two groups for the total obvious effect rate of cough and expectoration were - 2.36, and 95% CI was [- 3.41, - 1.31]; Improve the time of pulmonary rales MD -2.30, 95% CI [- 2.61, - 2.00]; The WMD between the two groups in absorption of chest x-ray shadow was -2.36 and 95% CI [-2.52, -2.20]. Serious systematic adverse reactions had not been reported in the trials.

CONCLUSIONThe effect of combined therapy with Reduning injection plus antibiotics and basic therapy is better than that of antibiotics plus basic therapy. Reduning injection can improve the symptoms of cough and expectoration, shorten the fever time and facilitate the absorption of chest x-ray shadow without any significant adverse reactions. However, further high quality trials are needed.
