Cancer pain is one of the main symptoms of patients suffering from malignant tumors. If it is not timely treated, it will lead to refractory pain and increase the burden on both the individuals and society. In China, the program titled" Good Pain Management" has been carried out for nearly 7 years, which increases the overall assessment and treatment levels for cancer pain among medical personnel. Nevertheless, the clinical efficacy for cancer pain treatment is not satisfactory. As an important treatment for malignant tumors, radiation therapy is also one of the main methods for treating cancer pain. For the first time, we proposed the concept of " peri-radiotherapeutic period" , and emphasized the continuous analgesic treatment for patients with cancer pain before, during and after radiotherapy. In this article, current status of cancer pain treatment at home and abroad was illustrated, and standardized assessment and management of cancer pain during the " peri-radiotherapeutic period" were summarized.

ObjectiveTo explore the effect of acupuncture combined with training of the modified rehabilitation apparatus on upper limb motor function of patients with ischemic stroke.Methods86 patients with ischemic stroke were divided randomly into the treatment group ( treated by acupuncture combined with training of the rehabilitation apparatus) and the control group (treated by simple acupuncture). The upper limb motor function of two groups was evaluated by Fugl-Meyer Assessment (FMA) before and after treatment.ResultsAfter 28 days treatment, scores of FMA of two groups were all raised significantly, but it was significantly greater for the treatment group than the control group (P<0.01).ConclusionIt is shown that acupuncture combined with training of the rehabilitation apparatus can improve the upper limb motor function and activity of daily living of patients with ischemic stroke.

Objective:To identify the risk factors for simple congenital ptosis.Methods:A case-control study was performed.A total of 106 children diagnosed with simple congenital ptosis at the Second Affiliated Hospital of Zhejiang University School of Medicine from October 2018 to January 2021 were recruited as a case group, and 106 sex-matched children without congenital abnormalities were enrolled as a control group at the same period.Ophthalmic examinations, including interpalpebral fissure height and margin reex distance 1, were performed on all participants.A questionnaire survey was administered to their mothers.The questionnaire included demographic information, prenatal maternal diseases, medical treatments and environmental exposures during pregnancy.Univariate analysis was used to compare the differences in variables between the case and control groups.Variables with P<0.20 were retained for multivariate logistic regression analysis to identify the risk factors for simple congenital ptosis.The goodness of fit of the model was evaluated by the Hosmer-Lemeshow test, and collinearity was assessed by the variance inflation factor (VIF). This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of the Second Affiliated Hospital of Zhejiang University School of Medicine (No.2019-136). The method and purpose of the study were fully explained to the children's guardians and written informed consent was obtained. Results:Comparisons of gestational age <37 weeks, birth order ≥2, maternal age, antibiotic use in the first trimester, paternal smoking ≥half a pack per day, and prenatal maternal passive smoking between the two groups were all with P<0.20.Multivariate logistic regression analysis showed that gestational age <37 weeks (odds ratio [ OR]=4.58; 95% confidence interval [ CI]: 1.24-16.85), paternal smoking ≥half a pack per day ( OR=2.28; 95% CI: 1.22-4.28) and prenatal maternal passive smoking ( OR=3.13; 95% CI: 1.16-8.41) were risk factors for simple congenital ptosis.No significant collinearity was found among these identified factors (all VIF<5). Conclusions:Preterm birth, paternal smoking, and prenatal maternal passive smoking are risk factors for simple congenital ptosis.

Objective To explore the relationship and influencing factors between pre‐diabetes mellitus (pre‐DM) and hypertension, providing evidence for formulating strategies for cardiovascular disease prevention and control. Methods We conducted this study from June 2013 to September 2014. Using stratified multistage random sampling, participants were administered a questionnaire survey, their height, weight, waist circumference, hip circumference, other physical attributes, blood pressure and blood lipids were measured. They also underwent the 75‐g glucose tolerance test and other laboratory examinations. A logistic regression model was used to analyze the relationship between pre‐DM and hypertension and its influencing factors. Results A total of 4 002 participants completed the survey. Participants'mean age was 50.3 ± 11.8 years. Of the total participants, 1 962 (49.0%) were males, while 2 039 (51.0%) were females; 1 participant had missing gender data. Further, 2 188 participants had normal glucose metabolism, 1 066 had pre‐DM, and 748 had diabetes. The prevalence of hypertension in participants with normal glucose metabolism, impaired fasting glucose, impaired glucose tolerance, both impaired fasting glucose and impaired glucose tolerance, and DM was 28.3%, 46.5%, 46.3%, 62.0%, and 61.2%, respectively. The prevalence of hypertension varied among people with different glucose metabolism (χ2=306.672, P<0.001). The prevalence of hypertension in the pre‐DM population increased with the aggravation of abnormal glucose metabolism compared to the normal glucose metabolism population, with a linear trend (χ2=299.009, P<0.001). Among those with abnormal glucose metabolism, there were differences in age, cholesterol, triglycerides, low‐density lipoproteins, body mass index, and waist circumference compared to those without hypertension (P<0.05). The risk of hypertension in the pre‐diabetic population was 1.5 times higher than that in the normal glucose metabolism population (OR=2.510, 95% CI: 2.156-2.922, P<0.001). There was no difference in the correlation intensity between pre‐DM and hypertension when gender was taken into account. Age and lipid abnormalities slightly decreased the correlation intensity between abnormal glucose metabolism and hypertension. Considering body mass index and centripetal obesity, the correlation intensity between abnormal glucose metabolism and hypertension could be reduced by controlling these factors. Conclusion The prevalence of hypertension is high in people with pre‐DM. There is a correlation between pre‐DM and hypertension, even when considering factors such as age, dyslipidemia, body mass index, and centripetal obesity. Therefore, it is necessary to strengthen the management of blood pressure in the pre‐diabetic population; improve early intervention for risk factors such as dyslipidemia, body mass index, and centripetal obesity; and reduce the occurrence of hypertension.

Objective To evaluate the safety and efficacy of induced hypotension and hypotension in carotid endarterectomy (CEA).Methods Data of 1 486 patients who underwent CEA in multicenters from Aug 2012 to Aug 2018 were retrospectively analyzed.After screening,a total of 1 448 patients met the inclusion criteria.Induced hypertension and hypotension was used in all thees patients.Results 87.8％ of the patients were with severe carotid stenosis.The average operative time was (51.8 ± 6.1) min,and the internal carotid artery clamping time was (11.4 ± 3.1) min.After induced hypertension,the stump pressure were higher than that before,of which 1 438 (99.3％) were greater than 50 mmHg.Monitoring of EEG oxygen saturation showed that the value of ipsilateral rSO2 was significantly lower than that of the contralateral [(56％ ± 3％) vs.(64％ ± 4％),P ＜ 0.05] before induced hypertension.After induced hypertension and clamp removal,the value of ipsilateral rSO2 was lower than that of the contralateral,but there was not significant difference (all P ＞ 0.05).Perioperative cerebral infarction occurred in 2 cases,ipsilateral cerebral hemorrhage in 1 case,contralateral cerebral hemorrhage in 1 case and myocardial infarction in 2 cases.Connclusion The technique of induced hypotension and hypotension play a temporary role in brain protection for patients undergoing CEA.This study demonstrated the safety and effectiveness of induced hypertension and hypotension technique.
