Objective: To evaluate the thermal environment of different types of public places and the thermal comfort of employees, so as to provide scientific basis for the establishment of microclimate standards and health supervision requirements. Methods: From June 2019 to December 2021, 50 public places (178 times) of 8 categories in Wuxi were selected, including hotels, swimming pools (gymnasiums), bathing places, shopping malls (supermarkets), barber shops, beauty shops, waiting rooms (bus station) and gyms. In summer and winter, microclimate indicators such as temperature and wind speed were measured in all kinds of places, combined with the work attire and physical activity of employees in the places. Fanger thermal comfort equation and center for the built environment (CBE) thermal comfort calculation tool were used to evaluate the predicted mean vote (PMV), predicted percent dissatisfied (PPD) and standard effective temperature (SET) according to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 55-2020. The modification effects of seasonal and temperature control conditions on thermal comfort were analyzed. The consistency of GB 37488-2019 "Hygienic Indicators and Limits in Public Places" and ASHRAE 55-2020 evaluation results on thermal environment was compared. Results: The thermal sensation of hotel, barber shop staff and the gym front-desk staff were moderate, while the thermal sensation of swimming place lifeguard, bathing place cleaning staff and gym trainer were slightly warm in summer and winter. Waiting room (bus station) cleaning and working staff, shopping mall staff felt slightly warm in summer and moderate in winter. Service staff in bathing places felt slightly warm in winter, while staff in beauty salons felt slightly cool in winter. The thermal comfort compliance of hotel cleaning staff and shopping mall staff in summer was lower than that in winter (χ(2)=7.01, 7.22, P=0.008, 0.007). The thermal comfort compliance of shopping mall staff in the condition of air conditioning off was higher than that in the condition of air conditioning on (χ(2)=7.01, P=0.008). The SET values of front-desk staff in hotels with different health supervision levels were significantly different (F=3.30, P=0.024). The PPD value and SET value of the front-desk staff, and the PPD value of cleaning staff of hotels above three stars were lower than those of hotels below three stars (P<0.05). The thermal comfort compliance of front-desk staff and cleaning staff in hotels above three stars was higher than that in hotels below three stars (χ(2)=8.33, 8.09, P=0.016, 0.018). The consistency of the two criteria was highest among waiting room (bus station) staff (100.0%, 1/1) and lowest among gym front-desk staff (0%, 0/2) and waiting room (bus station) cleaning staff (0%, 0/1) . Conclusion: There are different degrees of thermal discomfort in different seasons, under the condition of air conditioning and health supervision, and the microclimate indicators can not fully reflect the thermal comfort of human body. The health supervision of microclimate should be strengthened, the applicability of health standard limit value should be evaluated in many aspects, and the thermal comfort of occupational group should be improved.

2.Investigation on "Fengshi (GB 31) for treating wind disorders".
Chinese Acupuncture & Moxibustion 2023;43(7):829-834
From the perspective of academic history, the paper reviews systematically the background and evolution of the understanding of "Fengshi (GB 31) for treating wind disorders". In the ancient literature, there are no direct relevant statement for the indication of Fengshi (GB 31) associated with "wind", and the consensus on "Fengshi for treating wind disorders" has not been made yet. Under the influence of acupoint theory in recent era and the syndrome differentiation for acupuncture treatment in modern time, this statement becomes a conventional understanding and acceptable gradually. Meanwhile, the understanding for Fengshi (GB 31) treating wind disorders tends to be generalized. Practically, Fengshi (GB 31) is applicable for the various disorders in the local and adjacent areas. It is necessary for modern acupuncture researchers to systematically collate, investigate and identify the knowledge content with a sense of familiarity so that the contemporary inheritance, development and application of traditional theoretical knowledge of acupuncture can be enhanced.

OBJECTIVE:
To explore influence of external factors of wind, cold and dampness on clinical symptoms in knee osteoarthritis (KOA) patients with different constitutions of traditional Chinese medicine.
METHODS:
A cross-sectional stratified study was performed to select 108 patients with GradeⅡKOA in Kellgren & Lawrence (K-L) classification, including 22 males and 86 females, aged from 47 to 75 years old with an average of (60.7±6.0) years old;body mass index(BMI) ranged from 17.87 to 31.22 kg·m-2 with an average of (23.80±2.86) kg·m-2. According to Classification and Judgment of TCM Physique (ZYYXH/T157-2009), the types of TCM physique were determined and divided into 4 layers according to the deficiency and actual physique. Among them, there were 24 patients without biased physique, 12 males and 12 females, aged from 51 to 73 years old with an average of(62.8±6.0) years old, BMI ranged from 17.87 to 31.14 kg·m-2 with an average of (24.32±3.25) kg·m-2;there were 46 patients with virtual bias constitution, including 7 males and 39 females, aged from 47 to 70 years old with an average of (60.0±5.8) years old, BMI ranged from 19.38 to 31.22 kg·m-2 with an average of(23.42±2.97) kg·m-2;There were 26 patients with solid bias constitution, including 2 males and 24 females, aged from 48 to 75 years old with an average of (60.4±5.8) years old, BMI ranged from 21.16 to 30.76 kg·m-2 with an average of (24.15±2.33) kg·m-2;there were 9 patients with special constitution, 1 male and 8 female, aged from 53 to 75 years old with an average of (59.8±7.5) years old, BMI ranged from 19.26 to 26.67 kg·m-2 with an average of (23.79±2.49) kg·m-2. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was used to evaluate severity of clinical symptoms. The wind-cold-dampness external factor score was calculated through the questionnaire of wind-cold-dampness syndrome scale to evaluate degree of influence of wind-cold-dampness external factor. Pearson correlation analysis and partial correlation analysis were used to calculate the correlation coefficient between severity of external factors affecting wind, cold and dampness and severity of clinical symptoms in patients with different TCM constitution stratification.
RESULTS:
There was no statistical significance between total score of wind-cold-dampness and WOMAC score in patients with no biased constitution and special condition. Total wind-cold-dampness score of patients with virtual biased constitution was positively correlated with WOMAC stiffness score (r=0.327, P=0.032), and total wind-cold-dampness score of patients with solid biased constitution was positively correlated with WOMAC pain score (r=0.561, P=0.005) and WOMAC overall score (r=0.446, P=0.033). After further adjusting for the interaction of external factors of wind-cold-dampness, there was no statistical significance between wind-cold-dampness scores and WOMAC scores in patients with solid biased constitution. The score of dampness and pathogenic factors was positively correlated with WOMAC stiffness score (r=0.414, P=0.007).
CONCLUSION
The external factors of wind-cold dampness have different effects on the clinical symptoms of KOA patients with different TCM constitutions. Compared with other constitutions, the rigid symptoms of patients with asthenic biased constitutions are more susceptible to dampness pathogenic factors.

OBJECTIVE:
To compare the clinical therapeutic effect between deep needling at Xiaguan (ST 7) with round sharp needle combined with plum-blossom needle and conventional acupuncture in patients with trigeminal neuralgia (TN) of wind and heat, and explore its mechanism.
METHODS:
A total of 60 patients with TN of wind and heat were randomized into an observation group (30 cases) and a control group (30 cases). In the observation group, deep needling with round sharp needle was applied at Xiaguan (ST 7), and tapping with plum-blossom needle was applied at Yangbai (GB 14), Quanliao (SI 18), Dicang (ST 4), Sibai (ST 2), etc. of affected side. In the control group, conventional acupuncture was applied at the same acupoints selected in the observation group. The treatment was given once a day, 5 times a week for 4 weeks in the both groups. Before and after treatment, the scores of short-form McGill pain questionnaire (SF-MPQ), TCM syndrome, patient global impression of change (PGIC) and comprehensive symptom were observed, the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), vasoactive intestinal peptide (VIP) and β-endorphin (β-EP) were detected, and the adverse reaction was observed in the both groups.
RESULTS:
After treatment, the scores of PRI, PPI, VAS, TCM syndrome, PGIC and comprehensive symptom and the serum levels of IL-6, TNF-α and VIP were decreased compared before treatment in the both groups (
CONCLUSION
Deep needling at Xiaguan (ST 7) with round sharp needle combined with plum-blossom needle can effectively treat the trigeminal neuralgia of wind and heat and relieve pain, its therapeutic effect is superior to conventional acupuncture. The mechanism may be related to the regulation of serum IL-6, TNF-α, VIP and β-EP.

To systematically evaluate the efficacy and safety of Ganmao Qingre Granules in treatment of children with wind-cold syndrome. The study systematically retrieved CNKI, WanFang, VIP, CBM, PubMed, EMbase and Cochrane Library for children cases with wind-cold syndrome treated with RCT. The literature inclusion criteria provided by Cochrane was used to evaluate the litera-ture quality, and Meta-analysis was conducted by RevMan 5.3 software. A total of 6 literatures were included, with a total sample size of 492 cases, including 246 cases in the experimental group and 246 cases in the control group. According to the results of Meta-analysis, the experimental group recorded the hypothermia time(MD=-0.38, 95%CI[-0.53,-0.23], P<0.01), the total clinical effective rate(RR=1.25, 95%CI[1.15, 1.36], P<0.01), the cough relief time(MD=-2.75, 95%CI[-3.05,-2.46], P<0.01), the decrease nasal congestion relief time(MD=-1.45, 95%CI[-1.69,-1.22], P<0.01), traditional Chinese medicine syndrome score(MD=-8.35, 95%CI[-9.35,-7.36], P<0.01), all of them were superior to those of the control group(Aminophenol Huangnamin Granules), with statistically significant differences. Only 2 literatures mentioned no obvious adverse reaction, and the other 4 literatures did not mention any adverse reactions. Based on the results of this study, it was indicated that Ganmao Qingre Granules were effective in the treatment of children with wind-cold syndrome, but with unclear adverse reactions. Due to the insufficient quantity and low quality of included literatures, the efficacy and safety need to be further confirmed by more high-quality clinical studies.

8.Cold-associated skin disorders
Journal of the Korean Medical Association 2019;62(4):193-196
The human capacity for physiologic adaptation to cold is minimal. A cold environment can be a threat to the skin, leading to a subsequent fall in core body temperature. Many physiologic, behavioral, and environmental factors predispose to the global effects of cold injuries. Physical injuries caused by cold have two forms: systemic forms such as hypothermia and localized forms such as frostbite. Reduced temperature directly damages the tissue, as in frostbite and cold immersion foot. Vasospasm of vessels perfusing the skin induces chilblain, acrocyanosis, and frostbite. The degree of damage caused by cold is related to four factors: temperature, exposure time, wind intensity (temperature sensation), and high altitude.

BACKGROUND: This study investigated the effect of fine dust concentrations in the air on the incidence of viral respiratory infections in the Republic of Korea.METHODS: A time series analysis using R statistics was performed to determine the relationship between weekly concentrations of fine dust in the air and the incidences of acute respiratory tract infections caused by the respiratory syncytial virus (RSV), adenovirus (HAdV), rhinovirus (HRV), human metapneumovirus (HMPV), human coronavirus (HCoV), human bocavirus (HBoV), human parainfluenza virus (HPIV), and influenza virus (IFV), from the beginning of 2016 to the end of 2017. Correlations between various meteorological factors and the amount of fine dust were analyzed using the Spearman's rank correlation coefficient. To analyze the relationship between viral infections and fine dust, a quasi-poisson analysis was performed.RESULTS: The incidence of the HAdV was proportional to fine dust and air temperature. The IFV was proportional to fine dust and relative humidity and was inversely proportional to temperature. The HMPV was proportional to fine dust, wind speed, and inversely proportional to relative humidity. The HCoV was proportional to micro dust, relative humidity, and inversely proportional to temperature. Both the HBoV and HPIV were directly proportional to fine dust, temperature, wind speed, and inversely proportional to relative humidity. The RSV was inversely proportional to fine dust, temperature, wind speed. A lag effect was observed for the influenza virus, in that its incidence increased 2–3 weeks later on the cumulative lag model.CONCLUSION: As the weekly average concentration of fine dust increases, the incidence of HAdV, HMPV, HCoV, HBoV, HPIV, and influenza increase.

Arthropod-borne viruses (Arboviruses) are transmitted by arthropods such as Culicoides biting midges and cause abortion, stillbirth, and congenital malformation in ruminants, apparently leading to economic losses to farmers. To monitor the distribution of Culicoides and to determine their relationship with different environmental conditions (temperature, humidity, wind speed, and altitude of the farms) on 5 cattle farms, Culicoides were collected during summer season (May-September) in 2016 and 2017, and analyzed for identification of species and detection of arboviruses. About 35% of the Culicoides were collected in July and the collection rate increased with increase in temperature and humidity. The higher altitude where the farms were located, the more Culicoides were collected on inside than outside. In antigen test of Culicoides against 5 arboviruses, only Chuzan virus (CHUV) (2.63%) was detected in 2016. The Akabane virus (AKAV), CHUV, Ibaraki virus and Bovine ephemeral fever virus (BEFV) had a positive rate of less than 1.8% in 2017. In antigen test of bovine whole blood, AKAV (12.96%) and BEFV (0.96%) were positive in only one of the farms. As a result of serum neutralization test, antibodies against AKAV were generally measured in all the farms. These results suggest that vaccination before the season in which the Culicoides are active is probably best to prevent arbovirus infections.
