China Oncology 2016;26(8):687-692
Background and purpose:The incidence of lung cancer with brain metastasis tends to go up. The technique of intensity-modulated radiotherapy (IMRT) with simultaneous integrated boost (SIB) for tumor bed is a new treatment choice for patients with brain metastasis. This study aimed to investigate the feasibility of IMRT combined with SIB for tumor bed in the treatment of brain metastases of lung cancer by exploring its short-term clinical effect and treatment-related toxicities.Methods:Thirty-two patients who were diagnosed as having lung cancer with 1-4 brain metastases were prospectively collected. All the brain metastases were treated with whole brain 5 ifelds IMRT (40 Gy/20 f) combined with SIB (50 Gy/20 f). The dosage distribution within the target volume and dose-volume histogram were evaluated. Meanwhile, the overall response rate of radiotherapy, thelocal tumor control rate, 1-year survival rate, treatment-related acute and late toxicities were also calculated.Results:All patients were treated with IMRT successfully. The rate of Grade 2 vomitting, nausea, epilepsy was 9.4%, 15.6%, and 12.5%, respectively. Two cases had Grade 2 cognitive impairment, 4 cases had Grade 2 memory injury, and 2 cases had Grade 3 memory injury. There were no any Grade 4 events of acute and late toxicities. The overall response rate of radiotherapy was 71.9%. The local tumor control rate was 96.9%, and 1-year survival rate was 44%.Conclusion:It is feasible to use 5 ifelds IMRT (40 Gy/20 f) combined with SIB (boosting 10 Gy, i.e. total dose 50 Gy/20 f) for the treatment of brain metastases of lung cancer.

Objective To evaluate clinical effect of Compound Fanshiliu Recipe(CFR) for the treatment of over-weighted type 2 diabetes mellitus(T2DM). Methods One hundred and twenty over-weighted T2DM patients were randomized into treatment group and control group, 60 cases in each group. Both groups were given oral use of Metformin Hydrochloride Enteric-Coated Tablets, and additionally the treatment group was treated with CFR orally. The treatment of both groups lasted for 12 continuous weeks. Before and after treatment, we detected the waist circumference (WC), body mass index (BMI), and the levels of fasting blood glucose(FBG), postprandial 2-hour blood glucose(P2hBG), glycosylated hemoglobin(HbA1c), total cholesterol(TC), triglyceride (TG), and free fatty acid (FFA). The therapeutic effect of the two groups was also evaluated after treatment. Results (1) The total effective rate for traditional Chinese medical symptoms was 95.00% in the treatment group, and was 70.00%in the control group, the difference being significant(P<0.01).(2) After treatment, WC and BMI were decreased in the treatment group(P<0.01 compared with those before treatment), but had no significant decrease in the control group(P>0.05). The decrease of WC and BMI of the treatment group was superior to that of the control group(P<0.05).(3) After treatment, levels of FBG, P2hBG, HbA1c, TC, TG, and FFA of both groups were significantly improved (P<0.05), and the improvement of the treatment group was superior to that of the control group(P<0.05).(4) Three patients of the treatment group suffered from slight gastric discomfort, and the discomfort was relieved without any special treatment. Other patients of the two groups had no adverse reaction. Conclusion Treatment of CFR combined with Metformin has been proved to be an effective and safe approach to decrease blood glucose and blood lipid levels, promote weight loss, and ameliorate traditional Chinese medical symptoms.

Abstract: Objective To investigate the pollution of paralytic shellfish poisons (PSP) in shellfish sold in Hainan Province from 2018 to 2021. Methods From 2018 to 2021, the content of 10 paralytic shellfish poisons including saxitoxin (STX), neosaxitoxin (neoSTX), gonyautoxins 1 (GTX1), gonyautoxins 2 (GTX2), gonyautoxins 3 (GTX3), gonyautoxins 4 (GTX4), gonyautoxins 5 (GTX5), decarbamoylsaxitoxin (dcSTX), decarbamoylgonyau toxins 2 (dcGTX2) and decarbamoylgonyau toxins 3 (dcGTX3) in 7 kinds of shellfish commonly sold in 13 cities and counties in Hainan province was analyzed. Results The detection rate of PSP in 360 shellfish samples was 10.3%. Among them, the highest detection rate of STX was 5.83%, followed by GTX2 detection rate of 4.17%; the detection rate of neoSTX and GTX3 were both 1.67%; the detection rate of GTX1 was 1.39%. None of the five PSP, GTX4, GTX5, dcSTX, dcGTX2 and dcGTX3, were detected. Four types of PSP were detected in fanscallops, two were detected in oysters, mussels and Scapharca subcrenata, only one was detected in scallops, and no toxin contamination was detected in clams and razor clams. A single sample of fanscallops detected a maximum of 4 PSP, and a single sample of oysters, scallops, mussels and Scapharca subcrenata detected a maximum of 1 PSP. The equivalence of PSP in all samples was ND-155.6 μg/kg.The annual detection rate of PSP from high to low was: 20.0% in 2020, 15.6% in 2019, 5.3% in 2018, and 2.0% in 2021, and none of the samples tested exceeded the standard. Continuously detectable STX in 2018-2020, all PSP that could be detected in 2018 were STX. In 2019, in addition to STX detected in scallops and Scapharca subcrenata, neoSTX was also detected in oysters, mussels and Scapharca subcrenata. In 2020, PSP was only detected from scallops, and GTX2 could be detected in all positive specimens, while 5 STX, 5 GTX1 and 6 GTX3 were detected. Only GTX2 detected from scallops in 2021. STX was detected in shellfish sold in 12 cities and counties, GTX2 can be detected in 10 cities and counties, neoSTX can be detected in 5 cities and counties, GTX1 and GTX2 were detected in 4 cities and counties respectively. Shellfish sold in Wenchang and Lingshui markets can detect 5 types of PSP. Conclusion Some types of shellfish on the market in Hainan are contaminated with some kind of PSP pollution risks, and it is necessary to strengthen the supervision of PSP in marketed shellfish.
