Personalized medicine emphasizes individualized and dynamic treatment decisions. There is an urgent need for a new efficacy evaluation system that can adapt to this approach. By reviewing past clinical research practices， this article pointed out the innovative needs of traditional Chinese medicine （TCM） efficacy evaluation from the perspective of personalized medicine in terms of ethical review， trial design， data management， and statistical analysis. Focusing on these needs， the article has proposed a strategic framework using syndrome differentiation and treatment in TCM as an example. The framework includes a method based on subgroup dynamic-static parallel group design and analysis， a safeguard mechanism of continuous review， dynamic informed consent， and multicenter ethical review， a technological support platform for personalized clinical efficacy evaluation and evidence support， and a statistical strategy integrating Bayesian and traditional analysis methods， aiming to promote the development of personalized TCM diagnosis and treatment.

The Ehlers-Danlos syndrome(EDS)is a rare inherent connective tissue disorder.The prev-alence of EDS in the population is estimated at one out of ten thousand to one out of a hundred thousand.The vascular EDS(vEDS)are rare among the subtypes but are the worst in prognosis.The article reports a case of vEDS admitted to the hospital.The patient was a young man complaining of a sudden onset of aphasia in right hemiparalysis and severe left abdominal pain for unknown reasons.The diagnosis was made after the genetic testing.The patient suffered from vEDS.Then,the multi-disciplinary team(MDT)made a treatment plan tailored to this young patient.The complexity in classification and delusive presentations of the EDS make the correct diagnosis very challenging.This article hopes to report this case and to share the experiences to the bet-ter understanding of this disease.

Background:Transcranial alternating current stimulation (tACS) offers a new approach for adult patients with major depressive disorder (MDD).The study is to evaluate the efficacy and safety of tACS treating MDD.Methods:This is an 8-week,double-blind,randomized,placebo-controlled study.Ninety-two drug-naive patients with MDD aged 18 to 65 years will receive 20 daily 40-min,77.5-Hz,15-mA sessions of active or sham tACS targeting the forehead and both mastoid areas on weekdays for 4 consecutive weeks (week 4),following a 4-week observation period (week 8).The primary outcome is the remission rate defined as the 17-item Hamilton depression rating scale (HDRS-17) score ≤7 at week 8.Secondary outcomes are the rates of response at weeks 4 and 8 and rate of remission at week 4 based on HDRS-17,the proportion of participants having improvement in the clinical global impression-improvement,the change in HDRS-17 score (range,0-52,with higher scores indicating more depression) over the study,and variations of brain imaging and neurocognition from baseline to week 4.Safety will be assessed by vital signs at weeks 4 and 8,and adverse events will be collected during the entire study.Discussion:The tACS applied in this trial may have treatment effects on MDD with minimal side effects.

Lung cancer is the leading cause of cancer death and the most common malignant tumor, the long-term survival of which has stagnated in the past several decades. Pileostegia tomentella Hand. Mazz is a traditional Chinese medicine called "Zhongliuteng" (ZLT) in the pharmacopeia, which has been proved to possess a potent anti-tumor effect on various cancers. In this study, the effects of ZLT N-butanol extraction (ZLTN) and ZLT ethyl acetate extraction (ZLTE) on the viability of non-small cell lung cancer cell (NSCLC) lines H1299 and A549 were evaluated. Here, we firstly reported that ZLTE significantly inhibited H1299 cells growth without affecting the release of lactate dehydrogenase (LDH). In addition, ZLTE induced caspase-dependent apoptosis in a concentration-dependent manner and increased the expression cleaved-PARP and decreased pro-caspase-3, pro-caspase-7, pro-caspase-8, and pro-caspase-9. Moreover, ZLTE increased the level of cellular reactive oxygen species (ROS) in H1299 cells to lead to apoptosis, which was reversed by N-acetyl-cysteine (NAC). Taken together, our results revealed that ZLTE induced caspase-dependent apoptosis via ROS generation, suggesting that ZLTE is a promising herbal medicine for the treatment of NSCLC.

INTRODUCTION: Elderly persons who live alone are more likely to be socially isolated and at increased risk of adverse health outcomes, unnecessary hospital re-admissions and premature mortality. We aimed to understand the health-seeking behaviour of elderly persons living alone in public rental housing in Singapore. METHODS: In-depth interviews were conducted using a semi-structured question guide. Participants were selected using a purposive sampling approach. Interviews were conducted until theme saturation was reached. Qualitative data collected was analysed using manual thematic coding methods. RESULTS: Data analysis revealed five major themes: accessibility of healthcare services and financial assistance schemes; perceived high cost of care; self-management; self-reliance; and mismatch between perceived needs and services. CONCLUSION Elderly persons living in one-room rental flats are a resilient and resourceful group that values self-reliance and independence. Most of the elderly who live alone develop self-coping mechanisms to meet their healthcare needs rather than seek formal medical consultation. The insightful findings from this study should be taken into consideration when models of healthcare delivery are being reviewed and designed so as to support the disadvantaged elderly living alone.

Objective To study the first-time killing efficacy and the chain-killing efficacy of four gel baits against Blattella germanica: 1% chlorpyrifos, 0.05% fipronil, 2.15% imidacloprid, and 0.5% dinotefuran and provide a basis for drug selection in controlling Blattella germanica. Methods Laboratory killing efficacy test was conducted according to the national standard GB/T 13917.7-2009 and the chain-killing efficacy test was conducted for three rounds.The first round of chain efficacy test was conducted by feeding the cockroaches killed in the laboratory efficacy test, and each next round by feeding the cockroaches killed in the last round.Median lethal time (LT₅₀), 95% confidence limit, and toxicological regression equation of each test were calculated by software DPS V9.01. Results The LT₅₀ of the efficacy test with 1% chlorpyrifos gel bait was 0.745 5 (0.603 4-0.890 3) d.The LT₅₀ of the first, second and third chain experiments increased by 3.30, 2.18 and 2.76 times, respectively.The LT₅₀ of the efficacy test with 0.05% fipronil gel bait was 0.846 5(0.464 7-1.228 0)d, and increased by 5.42, 2.09 and 1.48 times, respectively, in the first, second and third chain experiments.The LT₅₀ of the efficacy test with 2.15% imidacloprid gel bait was 3.192 1(2.865 0-3.506 0)d, and increased by 1.13, 1.65 and 1.15 times, respectively in the first, second and third chain experiments.The LT₅₀ of the efficacy test with 0.5% dinotefuran gel bait was 0.997 1(0.805 8-1.191 6) d, and increased by 3.85, 1.37 and 1.78 times, respectively in the first, second and third chain experiments. Conclusion In the laboratory killing efficacy test, 1% chlorpyrifos, 0.05% fipronil, and 0.5% dinotefuran gel baits are better than 2.15% imidacloprid gel bait.In the chain-killing efficacy test, 2.15% imidacloprid and 0.5% dinotefuran gel baits are better than 1% chlorpyrifos and 0.05% fipronil gel baits.Based on our results, we recommend the use of 0.5% dinotefuran gel bait for comprehensive and sustained killing effect.

Objective To learn the population and infestation rates of cockroaches from 2017 to 2019 in Jiading District of Shanghai, to evaluate the effect of cockroach termination in household, and to provide information for cockroach control. Methods Cockroaches were controlled by dinotefuran baits and clean-up in households.Sticky trap and visual method were employed for density monitoring in farmers markets, supermarkets, hotels, restaurants, hospitals, and residential areas.Visual method was used in households before and after using the insecticide. Results Sticky trap result showed the room infestation rate was 3.24%, mean adhesion rate was 3.29%, the density was 0.06 per board, and the density peak appeared in May.Rate of invasion and density decreased year by year.Blattella germanica was the dominant species, counting for 71.88%.The density, and rate of infestation, as determined by sticky trap method, were the highest in the farmers markets, followed by hospitals and residential areas.Determined by visual method, room infestation rate was 1.16%, and the infestation rate was 4.44%.The peak appeared in January.Infestation rate of the farmers markets was the highest, followed by hospitals and residential areas.By visual method, the room infestation rate was 59.01%, and 48.45% for nymphs.The room infestation and ootheca rates were 54.04% and 17.39%.The rate decreased more than 80% in 30 days after use of the insecticide. Conclusion Infestation rate of cockroach remains at low level in Jiading District.The effect of bait combined with environmental cleaning is remarkable.Future work should strengthen monitoring and control in farmers markets, hospitals and residential areas.
