ObjectiveTo explore the clinical safety of Feilike Mixture （FLK） in the real world. MethodsThe safety of all children who received FLK from 29 institutions in 12 provinces between January 21，2021 and December 25，2021 was evaluated through prospective centralized surveillance and a nested case control study. ResultsA total of 3 035 juveniles were included. There were 29 research centers involved，which are distributed across 12 provinces，including one traditional Chinese medicine （TCM） hospital and 28 general hospitals. The average age among the juveniles was （4.77±3.56） years old，and the average weight was （21.81±12.97） kg. Among them，119 cases （3.92%） of juveniles had a history of allergies. Acute bronchitis was the main diagnosis for juveniles，with 1 656 cases （54.46%）. FLK was first used in 2 016 cases （66.43%），and 142 juvenile patients had special dosages，accounting for 4.68%. Among them，92 adverse drug reactions （ADRs） occurred，including 73 cases of gastrointestinal system disorders，10 cases of metabolic and nutritional disorders，eight cases of skin and subcutaneous tissue diseases，two cases of vascular and lymphatic disorders，and one case of systemic diseases and various reactions at the administration site. The manifestations of ADRs were mainly diarrhea，stool discoloration，and vomiting，and no serious ADRs occurred. The results of multi-factor analysis indicated that special dosages （the use of FLK）［odds ratio （OR） of 2.642， 95% confidence interval （CI） of 1.105-6.323］，combined administration： spleen aminopeptide （OR of 4.978， 95%CI of 1.200-20.655），and reason for combined administration： anti-infection （OR of 1.814， 95%CI of 1.071-3.075） were the risk factors for ADRs caused by FLK. Conclusion92 ADRs occurred among 3 035 juveniles using FLK. The incidence of ADRs caused by FLK was 3.03%，and the severity was mainly mild or moderate. Generally，the prognosis was favorable after symptomatic treatment such as drug withdrawal or dosage reduction，suggesting that FLK has good clinical safety.

Objective: To reveal the molecular biological mechanism of a rare Dc-variant individual using PacBio third-generation sequencing technology. Methods: ABO and Rh blood type identification, DAT, unexpected antibody screening and D antigen enhancement test were conducted by serological testing. The absorption-elution test was used to detect the e antigen. RHCE gene typing was performed by PCR-SSP, and the 1-10 exons of RHCE were sequenced by Sanger sequencing. The full-length sequences of RHCE, RHD and RHAG were detected by PacBio third-generation sequencing technology. Results: Serological findings: Blood type O, Dc-phenotype, DAT negative, unexpected antibody screening negative; enhanced D antigen expression; no detection of e antigen in the absorption-elution test. PCR-SSP genotyping indicated the presence of only the RHCE c allele. Sanger sequencing results: Exons 5-9 of RHCE were deleted, exon 1 had a heterozygous mutation at c. 48G/C, and exon 2 had five heterozygous mutations at c. 150C/T, c. 178C/A, c. 201A/G, c. 203A/G and c. 307C/T. Third-generation sequencing results: RHCE genotype was RHCE 02N. 08/RHCE-D(5-9)-CE; RHD genotype was RHD 01/RHD 01; RHAG genotype was RHAG 01/RHAG 01 (c. 808G>A and c. 861G>A). Conclusion: This Dc-individual carries the allele RHCE 02N. 08 and the novel allele RHCE-D(5-9)-CE. The findings of this study provide data support and a theoretical basis for elucidating the molecular mechanisms underlying RhCE deficiency phenotypes.

Aim To investigate the regulatory effect of geraniol on Nrf2/HO-1 signaling pathway after cerebral ischemia-reperfusion(I/R)in rats. Methods In this experiment,all the male SD rats were randomly divided into nine groups receiving the following treatments:sham operation(sham); sham operation+200 mg·kg-1 geraniol; I/R; I/R+50 mg·kg-1 geraniol; I/R+100 mg/kg geraniol; I/R+200 mg·kg-1 geraniol; edaravone; I/R+ brusatol(Nrf2 inhibitor); I/R+200mg·kg-1 geraniol+brusatol. All rats received intraperitoneal injection of geraniol for five consecutive days before MCAO and again after MCAO. During the construction of cerebral I/R injury models,the blood vessels were isolated without any suture in the sham operation and the sham operation +200 mg·kg-1 geraniol groups while the blood vessels with suture in other groups. The damage of neurological function was evaluated by the modified rating scale for neurological function. The TTC,HE and Tunel staining methods were used to determine the cerebral infarction volume,the damage of the ischemic cortex and the apoptosis of cortical cells,respectively. The oxidative stress-related parameters then were measured. The protein expressions of Nrf2 and HO-1 were detected by immunohistochemical staining and the target protein expressions of the injured cortex were detected by Western blot. Results Compared with the model group,it was found that the geraniol treatment significantly repaired neural injury,reduced cerebral infarction volume,cerebral cortex damage and cell apoptosis. Meanwhile,geraniol intervention could significantly increase the expression of Nrf2/HO-1 protein in the right-sided cortex and reduce oxidative stress level. Conclusion Geraniol can attenuate cerebral injury induced by ischemia-reperfusion in rats via activating Nrf2/HO-1 signaling pathway.

Objective To investigate the distribution of traditional Chinese medicine(TCM)syndrome types in diabetic kidney disease(DKD),and to explore the correlation between TCM syndrome types and laboratory indices,so as to provide an objective basis for the TCM syndrome differentiation and treatment of DKD.Methods Syndrome differentiation was carried out in the 157 patients with DKD at stages Ⅲ and Ⅳ,and then the distribution of the syndromes of deficiency in the origin and the syndromes of excess in the superficiality was explored.The levels of 24-hour urinary total protein(24hUTP),serum creatinine(Scr),blood urea nitrogen(UREA),plasma albumin(Alb),total cholesterol(TC),and triglyceride(TG)of the patients were detected,and then the relationship between the TCM syndrome types and the biochemical indexes was analyzed.Results(1)The distribution of the syndromes of deficiency in the origin in DKD patients at different stages showed that DKD patients at stage Ⅲ were mainly differentiated as yin deficiency and dryness-heat syndrome[58.57％(41/70)],qi and yin deficiency syndrome[28.57％(20/70)],yin and yang deficiency syndrome[10.00％(7/70)],and spleen and kidney qi deficiency syndrome[2.86％(2/70)];DKD patients at stage Ⅳ were mainly differentiated as yin deficiency and dryness-heat syndrome[40.23％(35/87)],qi and yin deficiency syndrome[29.89％(29/87)],spleen and kidney qi deficiency syndrome[18.39％(16/87)],and yin and yang deficiency syndrome[11.49％(10/87)].The differences in the distribution of the syndromes of deficiency in the origin among the DKD patients at different stages were statistically significant(P<0.05).However,with the progression of the disease,DKD patients at different stages in general showed a trend of the decrease in the proportion of yin deficiency and dryness-heat syndrome while the increase in the proportions of qi and yin deficiency syndrome,spleen and kidney qi deficiency syndrome,and yin and yang deficiency syndrome.(2)The distribution of the syndromes of excess in the superficiality in DKD patients at different stages showed that DKD patients at stage Ⅲ were mainly differentiated as damp-heat syndrome[54.29％(38/70)],phlegm-stasis syndrome[27.14％(19/70)],blood-stasis syndrome[10.00％(7/70)],and cold-damp syndrome[8.57％(6/70)];DKD patients at stage Ⅳ were mainly differentiated as damp-heat syndrome[44.83％(39/87)],phlegm-stasis syndrome[35.63％(31/87)],cold-damp syndrome[14.94％(13/87)],and blood-stasis syndrome[4.60％(4/87)].There were no significant differences in the distribution of the syndromes of excess in the superficiality among the DKD patients at different stages(P>0.05).(3)The analysis of relationship between TCM syndrome type and biochemical indexes showed that Scr and UREA levels of DKD patients with spleen and kidney qi deficiency syndrome were significantly higher than those of patients with yin deficiency and dryness-heat syndrome,and the differences were statistically significant(P<0.05);Scr and 24hUTP levels of DKD patients with cold-damp syndrome were significantly higher than those of patients with damp-heat syndrome,and the differences were statistically significant(P<0.05).Conclusion DKD patients at stages Ⅲ and Ⅳ are all predominantly suffering from yin deficiency and dryness-heat syndrome,and with the progression of the disease,the syndrome of yin deficiency and dryness-heat develops into qi and yin deficiency syndrome,spleen and kidney qi deficiency syndrome,and yin and yang deficiency syndrome sequentially.Pathogenic dampness and blood stasis are the main pathogenic factors of DKD.And Scr,UREA,and 24hUTP are correlated with the TCM syndrome types of DKD,which will be helpful for the differentiation of TCM syndrome types of DKD.
