OBJECTIVE: To compare the clinical features and follow-up results of systemic lupus erythematosus (SLE) between boys and girls. METHODS: A retrospective analysis was performed for the clinical data of 79 children (18 boys and 61 girls), aged ≤14 years, who were diagnosed with SLE from 2008 to 2018. The boys and the girls were compared in terms of initial and major clinical symptoms, injury of organs/systems, related laboratory markers, and follow-up results. RESULTS: As for the initial and non-initial symptoms, fever had the highest incidence rate in the boys, while facial erythema had the highest incidence rate in the girls. The boys tended to develop renal injury and hematological damage (P<0.05), with a significantly higher incidence rate of proteinuria than the girls (P<0.05), while the girls tended to develop joint pain (P<0.05). There were high abnormal rates (>80%) of anti-nuclear antibody, dsDNA, complement C3, and erythrocyte sedimentation rate in both boys and girls (P>0.05). The boys had a significantly higher disease activity than the girls at the first visit and in year 9 of follow-up (P<0.05). A one-month to ten-year follow-up showed that among the boys, 3 were lost to follow-up, 1 died, 7 were well controlled but required oral administration of large doses of hormones or immunosuppression, 2 progressed to chronic renal failure, and 1 developed lupus encephalopathy. Among the girls, 3 were lost to follow-up; 5 died; 34 were well controlled, among whom 5 were maintained on oral prednisone acetate with a dose of <10 mg, 1 was withdrawn from the drug for 1 year, and 2 were withdrawn from the drug for 2 years; 4 developed lupus encephalopathy; 1 developed depression and anxiety and had suicidal tendency in the 7th year after disease onset; 2 experienced impaired vision, blurred vision, and chloropsia; 1 developed a vascular necrosis of both femoral heads in the 3rd year of hormone administration. CONCLUSIONS There are differences in clinical features, several laboratory markers, and prognosis between boys and girls with SLE. Boys tend to have a high severity at disease onset, develop renal injury and hematological damage, and have poor long-term prognosis, while girls tend to have joint involvement.

OBJECTIVETo identify the differentially expressed proteins in the serum of patients with cervical cancer for use as the biomarkers for early diagnosis of cervical cancer.

METHODSSurface-enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS) with weak cationic chips (CM10) was used to examine the serum samples of 24 patients with cervical squamous cell carcinoma and 25 age-matched healthy women. The protein fingerprints were obtained, and bioinformatic analysis was performed to identify the differentially expressed proteins in the serum of the patients.

RESULTSFifty-two differentially expressed proteins were detected in the serum of cervical cancer patients (P<10(-5)), among which 6 proteins with mass/charge ratio of 4173.77, 5903.09, 6087.12, 10716.9, 6109.61 and 3397.41, respectively, showed lowered expression in the serum of cervical cancer patients. Two diagnostic models for cervical cancer were generated using software, including one consisting of the 4173.77(M/Z) protein with the diagnostic specificity of 96% and sensitivity of 75% for cervical cancer and the other consisting of 3 proteins at 5335.81(M/Z), 7562.99(M/Z), and 9287.89(M/Z) with specificity of 91.67% and sensitivity of 96.0%.

CONCLUSIONCervical cancer patients show different serum protein expression profile from healthy women. The 6 differential proteins identified may serve as specific serum biomarkers in close relation to the origin and progression of cervical cancer.

Objective To observe the effects of acupuncture on the level of inflammatory cytokines and toll-like receptor 4 in hypothalamic paraventricular nucleus (PVN) of SHR; To investigate the mechanisms of acupuncture in reduction of mean arterial blood pressure (MAP) in SHR. Methods Thirty 10-week old SHR were randomly divided into SHR group, acupuncture group and non-acupoint group, with 10 rats in each group. 10 WKY rats were set as control group. Acupuncture group received bilateral acupuncture in "Taichong" acupoint, and twisting and diarrhea method was used to stimulate; non-acupoint group received acupuncture at the back of feet, and soothing and diarrhea with twisting method was used to stimulate. Materials were taken two weeks later. The mean arterial pressure of rats was detected every day; the expression of TLR4 mRNA in PVN was detected by RT-PCR; The expression of TLR4 protein in PVN was detected by Western blot; The levels of TNF-αa nd IL-6 were detected. Results Compared with control group, the mean arterial pressure of SHR group increased; TLR4 mRNA and protein expression in PVN increased significantly; the level of TNF-α and IL-6 increased significantly (P<0.05). Compared with SHR group, the mean arterial pressure of acupuncture group decreased significantly;TLR4 mRNA and protein expression in PVN decreased significantly; the level of TNF-α and IL-6 decreased significantly (P<0.05). There was no significant change in non-acupoint group. Conclusion Acupuncture in"Taichong" acupoint can attenuate blood pressure of SHR by inhibiting expression of TLR4 in PVN and reducing the levels of TNF-α and IL-6.

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.
