ABSTRACT
Objective To investigate the epidemiological characteristics of varicella public health emergency events (PHEEs) in Xinwu District from 2016 to 2020, and to provide a scientific basis for formulating prevention and control measures. Methods Data was retrieved from “Public Health Emergency Management Information System” in "Chinese Disease Control Information System" and “Jiangsu Provincial Vaccine Management Information System”. Descriptive epidemiological methods were employed to analyze the data. SPSS software was used for statistical analysis. Results A total of 35 varicella PHEEs were reported in Xinwu District from 2016 to 2020, accounting for 57.38% of all PHEEs of infectious diseases in the same period. A total of 1 033 cases were reported, with an attack rate of 1.91%. The events showed a bimodal distribution. A small peak occurred from April to June, and the number of events accounted for 17.14%. A large peak occurred from November to January of the following year, and the number of events accounted for 82.86%. All events occurred in schools. Kindergartens were the most dangerous places, and the number of events accounted for 45.71%. Preschoolers aged 3-6 years accounted for 48.83% of the total cases, and the male-to-female ratio of students was 1.40:1. Among 234 cases with a history of immunization with Varicella Attenuated Live Vaccine (VarV), the longer the time interval from the date of VarV inoculation to the data of onset, the higher the proportion of varicella cases. Varicella PHEEs reporting time was positively correlated with duration (rs=0.391 , P<0.05). Conclusion Early detection, early reporting and early isolation can effectively control the duration of the event. School varicella surveillance should be strengthened during the epidemic peak period. Preschoolers are vulnerable groups. It is suggested that VarV should be included in the inspection work for enrollment in kindergartens.
ABSTRACT
Objective: To analyze and compare the efficacy and safety of pingyangmycin fibrin glue composite (PFG) and pingyangmycin dexamethasone composite (PD) in the treatment of pharyngolaryngeal venous malformation (VM). Methods: The clinical data of 98 patients with pharyngolaryngeal VM who underwent sclerotherapy with pingyangmycin composite in the First Affiliated Hospital of Sun Yat-sen University from June 2013 to November 2022 were retrospectively analyzed. According to their treatment, patients were divided into PFG group (n=34) and PD group (n=64), among those patients there were 54 males and 44 females, aged 1-77(37.06±18.86)years. The lesion size, total treatment times and adverse events were recorded before and after treatment. And the efficacy was divided into three grades: recovery, effective and invalid. According to the length of VM, all patients were divided into three subgroups, to compare the differences in efficacy and treatment times between each two groups.And finally the adverse events and their treatments were analyzed. SPSS 25.0 software was used for statistical analysis. Results: The efficacy of PFG group was 94.11%(32/34), the recovery rate was 85.29%(29/34).And the efficacy of PD group was 93.75%(60/64), the recovery rate was 64.06%(41/64). No serious adverse eventst occurred in subgroup comparison, there was no statistical difference between the two groups in efficacy and the times of treatments when the length was≤3 cm (Zefficacy=1.04, ttreatment times=2.18, P>0.05); when the length was 3-5 cm, there was no significant efficacy difference between the two groups(Zefficacy=1.17, P>0.05), but the treatment times of PFG were less (ttreatment times=4.87, P<0.01); when the length≥5 cm, efficacy of PFG was significantly better than PD (Zefficacy=2.94, P<0.01), and had fewer treatments times (ttreatment times=2.16, P<0.01). There were no serious adverse events in either group during treatment and follow-up. Conclusion: Both PFG and PD are safe and effective composite sclerotherapy agent for the treatment of laryngeal VM, but PFG has a higher cure rate and fewer treatment times for massive lesions.

Pyoderma gangrenosum (PG) is a rare chronic inflammatory non-infectious skin dermatosis, and there is no clear treatment guideline for this disease at home and abroad. There are a variety of clinical treatment methods for PG, including local therapy and systemic application of glucocorticoids, immunosuppressants, intravenous immuno- globulin, and biologics. Glucocorticoids are the first-line drugs commonly used in clinical practice, and immunosuppressants can be used alone or in combination with glucocorticoids. In recent years, more and more evidence has shown that biologics are a new trend in the treatment of PG, mainly including tumor necrosis factor α inhibitors, interleukin-1 (IL-1) inhibitors, IL-12/23 inhibitors, IL-17 inhibitors, rituximab, and small molecular inhibitors. This article summarizes the current status and latest progress in the treatment of PG, hoping to provide clinicians with ideas for the treatment of PG.

Objective:To evaluate the efficacy of Tui Na therapy combined with self-made Jianpi-Tiaogan Decoction in the treatment of anorexia in children. Methods:A total of 92 patients with pediatric anorexia in our hospital from January 2018 to June 2019 who met the inclusion criteria were divided into 2 groups by random number table method, with 46 patients in each group. The control group was treated with the Tui Na therapy mainly by manipulating on the abdomen and pushing the spleen, and the treatment group was given the self-made Jianpi-Tiaogan Decoction on the basis of the treatment of the control group. Both groups were treated for 4 weeks. The TCM syndrome scores were performed, serum Leptin and Ghrelin levels were measures by enzyme linked immunosorbent assay, serum neuropeptide Y (NPY) was measured by radioimmunoassay, contents of blood zinc and salivary amylase ptyalase were measured by flame atomic absorption spectrometry and Western blot, and D-xylose absorption test was carried out respectively before and after treatment. And the clinical efficacy was evaluated. Results:The total effective rate was 91.3% (42/46) in the treatment group and 73.9% (34/46) in the control group. The difference between the two groups was statistically significant ( χ2=4.821, P=0.028). After treatment, the scores of anorexia, antifeedance, irritability, agitation, hiccup and belching, fullness of chest and flank, thin shape, sleep difficulty and total score in the treatment group were significantly lower than those in the control group ( t values were 6.782, 7.524, 9.100, 5.643, 4.796, 6.066, 4.069, 3.197, 5.073, respectively, all Ps<0.01). After treatment, the serum NPY (133.7 ± 12.4 ng/L vs. 105.6 ± 10.8 ng/L, t=11.589) and Ghrelin (329.6 ± 26.1 ng/L vs. 275.4 ± 25.0 ng/L, t=12.211) levels in the treatment group were significantly higher than those in the control group ( P<0.01), but Leptin (21.7 ± 4.0 g/L vs. 25.2 ± 4.3 g/L, t=4.042) was significantly lower than that of the control group ( P<0.01). After treatment, blood zinc (9.9 ± 2.5 mol/L vs. 8.7 ± 2.3 mol/L, t=2.396), salivary amylase ptyalase content (23.5 ± 4.2 U/L vs. 17.9 ± 3.6 U/L, t=6.866), D-xylose absorption test (0.9 ± 0.4 ng/L vs. 0.7 ± 0.3 ng/L, t=2.713) were significantly higher than those in the control group ( P<0.05 or P<0.01). Conclusions:Tui Na therapy combined with self-made Jianpi-Tiaogan Decoction can improve TCM syndromes of children, regulate the levels of NPY, Leptin and Ghrelin, and improve clinical efficacy.

ABSTRACT
<p><b>BACKGROUND</b>Nowadays, social media tools such as short message service, Twitter, video, and web-based systems are more and more used in clinical follow-up, making clinical follow-up much more time- and cost-effective than ever before. However, as the most popular social media in China, little is known about the utility of smartphone WeChat application in follow-up. In this study, we aimed to investigate the feasibility and superiority of WeChat application in clinical follow-up.</p><p><b>METHODS</b>A total of 108 patients diagnosed with head and neck tumor were randomized to WeChat follow-up (WFU) group or telephone follow-up (TFU) group for 6-month follow-up. The follow-ups were delivered by WeChat or telephone at 2 weeks, 1, 2, 3, and 6 months to the patients after being discharged. The study measurements were time consumption for follow-up delivery, total economic cost, lost-to-follow-up rate, and overall satisfaction for the follow-up method.</p><p><b>RESULTS</b>Time consumption in WFU group for each patient (23.36 ± 6.16 min) was significantly shorter than that in TFU group (42.89 ± 7.15 min) (P < 0.001); total economic cost in WFU group (RMB 90 Yuan) was much lower than that in TFU group (RMB 196 Yuan). Lost-to-follow-up rate in the WFU group was 7.02% (4/57) compared with TFU group, 9.80% (5/51), while no significance was observed (95% confidence interval [CI]: 0.176-2.740; P = 0.732). The overall satisfaction rate in WFU group was 94.34% (50/53) compared with 80.43% (37/46) in TFU group (95% CI: 0.057-0.067; P = 0.034).</p><p><b>CONCLUSIONS</b>The smartphone WeChat application was found to be a viable option for follow-up in discharged patients with head and neck tumors. WFU was time-effective, cost-effective, and convenient in communication. This doctor-led follow-up model has the potential to establish a good physician-patient relationship by enhancing dynamic communications and providing individual health instructions.</p><p><b>TRIAL REGISTRATION</b>Chinese Clinical Trial Registry, ChiCTR-IOR-15007498; http://www.chictr.org.cn/ showproj.aspx?proj=12613.</p>

Morphological characteristics of hyphal interaction between Grifola umbellata (Pers. Ex Fr.) Pilat and its companion fungus which related to sclerotia formation from hyphae were investigated by external observations, light microscopy and transmission electron microscopy (TEM). External observations showed that a dense antagonism line was formed by both G. umbellata and companion fungus after their hyphae contacted each other in dual culture. Many hyphal strands emerged on the colony of G. umbellata and differentiated to sclerotia from where hyphal strands crossed. Light microscope observations revealed the process of antagonism line formation. Mature antagonism with structural differentiation, was composed of three main layers: the rind, the rind underlayer and the hypha layer. TEM observations showed that after colonies hyphal contact, a series of reactions always occurred in both G. umbellata and companion fungus. Cells in the center of antagonism line were dead. Cells of G. umbellata adjacent to the antagonism line were usually large and hollow, with unilateral thickened wall, whereas those of companion fungus were empty, with thin or thick wall. Both hyphal interaction at the antagonism line may be one of the main reasons for sclerotia of G. umbellata differentiation from hypha.
