OBJECTIVETo evaluate the efficacy and toxicity of concomitant chemo-radiotherapy (CCRT) followed by adjuvant chemotherapy (ACT) in Chinese patients with locoregionally advanced nasopharygeal carcinoma (NPC).

METHODSSeventy-four patients with stage III and IV (UICC1997) were treated by Intergroup 0099 regimen, consisting of CCRT using cisplatin 100 mg/m(2) on D1, 22, and 43 of radiotherapy, followed by ACT using cisplatin 80 mg x m(-2) x d(-1) and 5-Fu 1 g x m(-2) x 4 d(-1) given from D71, 99, and 127. All the patients were irradiated with conventional fractionation to a total dose of 68 Gy to the nasopharynx and 66 Gy to the neck. Acute toxicity and late complication were assessed by the RTOG radiation morbidity scoring scheme.

RESULTSWith a median follow-up of 49 months, the overall 5-year survival and relapse-free survival rates were 71.3% and 43.5% respectively. No grade 5 toxicity was observed in this series, the main grade 3/4 acute toxicity events were hematologic toxicity in 25 patients (33.8%), mucositis in 19 patients (25.7%), and grade 3 skin disease in 6 (8.1%), respectively. The compliance rates were 100.0% for radiotherapy, 75.7% for CCRT, and 47.3% for CCRT plus ACT. The main grade 3/4 late complications were severe salivary gland toxicity (17 cases), ear injury (13 cases), and the neck skin/subcutaneous tissue disease (7 cases). The 5-year cumulative incidence of late toxicity was 44.3%.

CONCLUSIONCompared with routine radiotherapy, the concomitant chemo-radiotherapy may improve the outcome of locoregionally advanced NPC in the Chinese patients, with higher incidence of severe acute toxicities and similar late complications.

In the studies of modern epidemiology, exposure in a short term cannot fully elaborate the mechanism of the development of diseases or health-related events. Thus, lights have been shed on to life course epidemiology, which studies the exposures in early life time and their effects related to the development of chronic diseases. When exploring the mechanism leading from one exposure to an outcome and its effects through other factors, due to the existence of time-variant effects, conventional statistic methods could not meet the needs of etiological analysis in life course epidemiology. This paper summarizes the dynamic path analysis model, including the model structure and significance, and its application in life course epidemiology. Meanwhile, the procedure of data processing and etiology analyzing were introduced. In conclusion, dynamic path analysis is a useful tool which can be used to better elucidate the mechanisms that underlie the etiology of chronic diseases.

OBJECTIVETo assess the clinical efficacy on post-stroke shoulder-hand syndrome (SHS) treated with acupuncture and rehabilitation and the impacts on patients' nailfold microcirculation.

METHODSOne hundred and twenty patients were randomized into an acupuncture rehabilitation group and a simple rehabilitation group, 60 cases in each one. In the simple rehabilitation group, OT (comprehensive rehabilitation therapy) training was adopted. In the acupuncture rehabilitation group, on the basis of the treatment as the simple rehabilitation, acu puncture was added at Taiyuan (LU 9), Zusanli (ST 36), Xuanzhong (GB 39), Waiguan (TE 5), Shousanli (LI 10), Quchi (LI 11) and Jianyu (LI 15). Acupuncture was given once a day, 7 days made one session. Totally, 4 sessions of treatment were required. Fugl-Meyer score, upper limb pain score, the score of nerve function defect and the items of nailfold microcirculation of patients were assessed in the the two groups before and after treatment. The efficacy was compared between the two groups.

RESULTS(1) The upper limb pain, the systematic motor function of the upper limbs, the nerve function defect, nailfold microcirculation and clinical symptoms were all improved after treatment in either the acupuncture rehabilitation group or the simple rehabilitation group as compared with those before treatment, indicating the significant difference (P<0. 05, P<0. 01). (2) The im provements in the upper limb pain (0. 90+/-0.71 vs 1. 80+/-0. 66), the systematic motor function of the upper limbs (42. 43 13. 57 vs 29. 98+/-15. 11), the nerve function defect (8. 60+/-11. 61 vs 13. 0+/-1. 74), nailfold microcirculation (total score 3. 18+/-1.32 vs 4.34+/-1.23) and clinical symptoms in the acupuncture rehabilitation group after treatment were different significantly as compared with those in the simple rehabilitation group (PO0. 05,P-O. 01), and the results in the acupuncture rehabilitation group were superior to the simple rehabilitation group. (3) In the acupuncture rehabilitation group, the markedly effective rate was 50. 0% (30/60) and the total effective rate was 93.3% (56/60), which was better than 16.7% (10/60) and 63. 3% (38/60) respectively in the simple rehabilitation group (all P<0. 05).

CONCLUSIONBoth the combined therapy of acupuncture and rehabilitation and the simple rehabilitation training are effective in the treatment of post-stroke SHS, and promote the status of nailfold microcirculation, the efficacy of the combined therapy is better than that of the latter.

Objective: To understand the clinical characteristics and economic burden of influenza-like illness (ILI) children aged 0-59 months in the outpatient settings in Suzhou, China, 2011-2017. Methods: From March 2011 to February 2017, we conducted a prospective surveillance program on ILI for children aged less than 5 years at Soochow University Affiliated Children's Hospital. Through standard questionnaires and follow-up survey via telephone, we collected information regarding the demographic characteristics, medical history, clinical symptoms and both direct and indirect costs associated with influenza, of the patients. We then compared clinical characteristics and economic burden of influenza A/H1N1, A/H3N2, and B infections among children with ILI. Results: We enrolled 6 310 patients with ILI from March 2011 to February 2017 and collected all their throat swabs. 791 (12.9%) of the swabs showed positive for influenza virus, including 88 (11.1%) subtype influenza A/H1N1, 288 (36.4%) subtype influenza A/H3N2, and 415(52.5%) type influenza B. The proportions of cough, rhinorrhea, wheezing, vomiting and convulsion in influenza-positive children were higher than those influenza-negative children. Except for the prevalence rates of cough (χ(2)=9.227, P=0.010), wheezing (χ(2)=7.273, P=0.026) and vomiting (χ(2)=8.163, P=0.017), other clinical symptoms appeared similar between the three viral subtypes. Among all the ILI children, the average total cost per episode of influenza was 688.4 Yuan (95%CI: 630.1-746.7) for influenza-negative children; 768.0 Yuan (95%CI: 686.8-849.3) for influenza-positive children and 738.3 Yuan (95%CI: 655.5-821.1) for influenza B. Children with influenza A/H1N1 spent much more than those with influenza A/H3N2 or influenza B in the total cost (χ(2)=7.237, P=0.028). Conclusion: Children infected influenza showed higher prevalence rates of cough, rhinorrhea, wheezing, vomiting and convulsion than those without influenza. Influenza A/H1N1 subtype caused heavier economic burden than the other two influenza subtypes.

Objective: To explore the association between nuclear factor kappa-light-chain-enhancer of activated genetic polymorphisms in B cells (NF-κB) and the HCV susceptibility, among the Chinese population. Methods: A total of 1 679 participants were enrolled; including 503 drug users and 1 176 other participants at risk under the exposure for blood. By using the logistic regression analysis, related risk factors for HCV infection among subjects were analyzed. Two NF-κB pathway variants, NF-κB1 rs72696119 and REL rs13031237 were then genotyped by TaqMan assay method. Logistic regression analysis was performed to analyze the association between gene polymorphisms and the susceptibility on HCV. Results: Among the drug users, women (OR=0.408, 95%CI: 0.308-0.767) appeared to be associated with the decreased risk for HCV infection, while factors as drug injection (OR=8.817, 95%CI: 5.577-13.937) and the duration of drug-intake >5.5 years (OR=2.891, 95%CI: 1.824-4.583) were associated with the increased risk for HCV infection. Among the participants who had been exposed to blood, women (OR=3.431, 95%CI: 2.360-4.988) were associated with the increased risk for HCV infection, while the levels of education beyond elementary school (OR=0.613, 95%CI: 0.429-0.876) were associated with the decreased risk for HCV infection. Compared to the reference NF-κB1 rs72696119 CC genotype, the carriage of GG genotype was associated with an increased risk of susceptibility on HCV (OR=1.412, 95%CI: 1.035-1.927) among the total study population. Results from the interaction analysis showed that there was no interactive effects appeared between rs72696119 and route of infection, or between rs72696119 and gender among the total population under study (all P>0.05). Conclusion: NF-κB1 polymorphism rs72696119 and related factors seemed associated with the susceptibility to HCV infection among high-risk Chinese populations.

Introduction: Atopic dermatitis (AD) is a complex disease with an interplay of genetic and environmental factors. In the United States, AD affects 10.7% of children andyc 7.2% of adults. Similarly in the Philippines, the prevalence of AD is 12.7% in the under 18 population, and 2% in the over 18 population. While AD affects all ages, the burden of the disease is greater in the pediatric population. The pathogenesis of AD is multifactorial. Variations in genes responsible for epidermal barrier function, keratinocyte terminal differentiation, and the innate and adaptive immune responses have been linked to AD. A null mutation involving the filaggrin gene is the strongest known risk factor for AD. This mutation results in a loss of filaggrin (FLG) protein by at least 50%. Filaggrin breakdown products form part of the natural moisturizing factor (NMF) of the skin, which is essential in skin hydration. A decrease in NMF and an increase in transepidermal water loss (TEWL) are observed in AD patients with FLG mutation. The defective barrier in AD patients decreases skin defenses against irritation and allergen penetration. Exposure to certain environmental chemicals like formaldehyde may worsen this barrier. This may lead to increased skin permeability to aeroallergens that leads to dermatitis in sensitized patients. Barrier defects may also play a role in epicutaneous sensitization and the subsequent development of other atopic conditions, such as bronchial asthma and allergic rhinitis. The Philippine Dermatological Society (PDS) consensus on AD aims to provide a comprehensive guideline and evidence-based recommendations in the management of this condition, with consideration of cultural factors that are often encountered in the Philippine setting. These guidelines are intended to provide practitioners with an overview of the holistic approach in the management of AD, ameliorating the negative effects of the disease and improving overall quality of life.. Methodology: A group of 21 board-certified dermatologists from the Philippine Dermatological Society (PDS) convened to discuss aspects in the clinical management of AD. Database and literature search included the full-text articles of observational studies, randomized controlled clinical trials, and observational studies using the Cochrane library, PubMed, Hardin (for Philippine based studies) as well as data from the PDS health information system. The terms used in combinations from the literature included “atopic dermatitis”, “atopic eczema”, “emollients”, “topical corticosteroids”, “topical calcineurin inhibitors”, “anti-histamines” and “phototherapy”. A total of fifty (50) full text articles were reviewed and found applicable for the scope of the study. Articles were assessed using the modified Jadad scale, with score interpretations as follows: (5- excellent, 3- good, 1– poor). Consensus guidelines for AD from within and outside of the region were also reviewed, from the 2013 Asia-Pacific guidelines, 2014 Taiwanese Dermatological Association consensus, 2016 guidelines in the management of AD in Singapore, 2014 American Academy of Dermatology guidelines, and the 2020 Japanese guidelines for AD. From the literature review, proposed consensus statements were developed, and a Delphi survey was conducted over two separate virtual meetings. Individual dermatologists provided Likert Scoring (1- strongly disagree to 5- strongly agree) based on consensus statements. A consensus was deemed reached at mean scores of > 4.00, a near consensus at > 3.5, and no consensus at <3.5. Summary: AD is a chronic relapsing condition with a significant burden of disease, most commonly affecting the pediatric population. The PDS AD Consensus Guidelines summarizes the standards of therapy and the therapeutic ladder in the management of AD based on published clinical trials and literature review. While these modalities remain the cornerstone of therapy, an individualized approach is the key to the holistic management of an AD patient. Knowledge and awareness of frequently associated conditions, whether in the realm of food allergies, contact allergies, or secondary infections, is paramount. In addition to the standard therapeutic armamentarium, the physician must also consider cultural practices and be knowledgeable of alternative therapeutic options. Referral to a specialist is recommended for recalcitrant cases of AD, or when initiation of systemic immunosuppressive agents, phototherapy, or biologic agents is contemplated.
