Objective:
To investigate the prevalence of hypertension among primary and middle school students living in Suzhou City, Jiangsu Province, so as to provide insights into comprehensive hypertension control among children and adolescents.
Methods:
Primary and middle school students at ages of 7 to 17 years were recruited for a questionnaire survey in Suzhou City using the stratified cluster random sampling method from September to December, 2020, and the height and body weight were measured. Blood pressure was measured at three separate clinic visits according to the national criteria Reference of Screening for Elevated Blood Pressure among Children and Adolescents Aged 7-18 Years ( WS/T 610-2018 ), and the detection of elevated blood pressure was estimated at three separate visits. In addition, factors affecting elevated blood pressure were identified.
Results:
A total of 3 713 students were enrolled, including 1 924 boys ( 51.82% ) and 1 789 girls ( 48.18% ). The detection of elevated blood pressure was 13.63%, 5.36%, and 3.37% at three separate visits, respectively, and the prevalence of hypertension ( elevated blood pressure at all three visits ) was 3.37%. The detection rates of elevated blood pressure were all higher at three visits ( 16.90%, 8.40%, and 5.26% ) among students at ages of 12 to 17 years than among students at ages of 7 to 11 years ( 9.65%, 1.67%, and 1.07%, P<0.05 ). The detection of elevated blood pressure was significantly higher in boys ( 15.23% ) than in girls (11.91%) at the first visit ( P<0.05 ), while no significant differences were seen at the second or third visit ( P>0.05 ). In addition, higher detection rates of elevated blood pressure were seen in obese ( 27.62%, 11.51%, and 7.06% ) and overweight students ( 17.45%, 6.95%, and 4.85% ) than in students with normal weight ( 9.44%, 3.54%, and 2.15% ) at all three visits, and greater detection rates of elevated blood pressure were found in obese students than in overweight students at the first and second visits ( P<0.017 ).
Conclusions
The prevalence of hypertension was 3.37% based on three separate visits among primary and middle school students in Suzhou City. Measurement of blood pressure at three separate visits within different days is effective to reduce the false positive rate of hypertension and decrease misdiagnosis among children and adolescents.

Objective To evaluate the risk of plague occurrence via surveying and analyzing indoor rat density and flea index in natural villages having previous plague experience. Methods During August to September 2007, 30 natural villages experiencing previous plague were selected based on the surveillance data, and then all households were coded with numbers and 20 households in each village were randomly selected via computer. Cages and sticky papers were set in 600 selected households to capture rats and fleas. Rat density, flea prevalence, flea index and median were estimated. Results One hundred thirty-three Rattus flavipectus and 33 Suncus murinus were caught and averaged rat density was 2.8 rats per one hundred cage. nights (166/6000), the median was 5 rats each village. One hundred and one mice infected fleas, flea prevalence on rats was 60.8% (101/166), 296 Xenopsylla cheopis and 48 Leptopsylla segnis were collected. Rat flea index was 2.1 fleas per rat (344/166). A total of 315 dissociated flea was caught, average dissociated flea index was 0.026 fleas per sticky paper (315/11888). The median was 5.5 dissociated fleas per village. Of dissociated fleas, Ctenocephalides felis felis (205) and Xenopsylla cheopis (103) accounted for 97.8% (308/315). The proportion for species of the rat flea and the dissociated flea was different(Fisher test: P < 0.01). The rat flea was significantly associated with the rat density(r = 0.68, P < 0.01), but the dissociated flea was significantly associated with neither the rat density(r = -yield than fried wheat batter(χ2 = 5.59, P < 0.05). Conclusions In these villages having previous plague experience of Lianghe County, Rattusflavipectus was dominant species of indoor rats, Xenopsylla cheopis and Ctenocephalides felis felis were dominant species of rat flea and dissociated flea, respectively. Mengsong, Bangdu, and Tangjiatun village had potential risk of plague emergence.

OBJECTIVETo investigate the expressions of caspase-8, receptor interacting protein (RIP) and nuclear factor (NF)-kappaBp65 in oral lichen planus (OLP) and their relationship with cell apoptosis.
METHODSImmunohistochemical technique with SP method was used to detect the expressions of caspase-8, RIP and NF-kappaBp65 in 30 OLP cases and 15 normal oral mucosa specimens. Terminal deoxynucleotidyl transferase-mediated nucleotide shift enzyme (TdT) mediated d-UTP end labeling (TUNEL) was used for detecting the cell apoptotic index (AI) in 15 OLP cases and 5 nomal oral mucosa specimens.
RESULTSCompared with the control group, the AI of epithelial cells (6.76 +/- 2.32) increased and the AI of lymphocytes (1.75 +/- 0.74)decreased in OLP (P < 0.01). The positive rate of caspase-8, RIP and NF-kappaBp65 of epithelial cells were 97% (29/30), 87% (26/30) and 93% (28/30) respectively, significantly higher in OLP than in normal control (P < 0.05). The positive rate of caspase-8, RIP and NF-kappaBp65 of lymphocytes were 100% (30/30, 90% (27/30) and 80% (24/30) respectively, significantly higher in OLP than in normal control (P < 0.01). A positive correlation was also observed between NF-kappaBp65 expression of lymphocytes and AI of epithelial cells.
CONCLUSIONSAccelerated apoptosis of the keratinocytes and inhibition of lymphocyte apoptosis may coexist and contribute to the formation and progression of OLP. The over expression of caspase-8, RIP and NF-kappaBp65 in OLP may play a role in the pathogenesis of OLP.

In this study, the COI barcode was used to identify the Scolopendra medicinal materials and its adulterants in order to provide a new method for the identification of Scolopendra. Genomic DNA was extracted from the experimental samples. The COI sequences were amplified and sequenced bi-directionally. Sequence alignment and NJ tree construction was carried out by MEGA6.0 software. The results showed that the COI sequences can be obtained from all experimental samples. The average inter-specific K2P distance of Scolopendra was 0.222 and the minimum inter-specific distance was 0.190. All the Scolopendra subspinipes mutilans medicinal samples clustered into a clade in the NJ tree and can be distinguished from its adulterants. In a conclusion, COI can be used to correctly identify Scolopendra medicinal materials, and it will be a potential DNA barcode for identifying other animal medicinal materials.

OBJECTIVETo detect the expressions of receptor-interacting protein (RIP) and caspase-8 and investigate their roles in oral squamous cell carcinoma (OSCC) and oral precancerous lesions.
METHODSSABC immunohistochemical methods were used to detect the expressions of RIP and caspase-8 in 22 specimens of OSCC, 14 specimens of oral lichen planus (OLP), 14 specimens of oral leukoplakia (OLK) and 10 specimens of normal oral mucosa (NOM).
RESULTSThe rate of weak or negative expression of RIP in normal mucosa was 50% (5/10). The rates of weak and positive expression of RIP in OLP, OLK and OSCC were 75% (36/50), and the rate of positive and strong expression of RIP was 63.7% (14/22) in OSCC, significantly higher that in the others groups (P<0.05). The rates of weak, positive and strong positive expression of caspase-8 in NOM, OLP, OLK and OSCC were 80% (8/10), 100% (14/14), 85.7% (12/14), and 100% (22/22), respectively.
CONCLUSIONBoth RIP and caspase-8 may play important roles in the occurrence and progression of OSCC and oral precancerous lesions.
