Objective To investigate the effect of Shenfuhuang injection (SFH Injection) on function of organs and mortality of septic rats, using a sepsis mode by cecal ligation puncture(CLP). Methods 140 male Wistar rats were randomly divided into four groups: normal control group, sham operation group, CLP group (being further divided into 2, 8, 24, 48 h subgroups), SFH injection treatment group (being further divided into 2, 8, 24, 48 h subgroups, drug were inraveous injected just after operation and per 12 h). The mortality of animals and altering organ’s function were observed within 7 days. Results Compared to CLP model, mortality of Septic rats in SFH injection group was significant lower, and the treatment prolonged survival duration. SFH Injection group owned lower numerical values of ALT, AST, BUN and Cr in serum. Conclusion SFH Injection can obviously decline the mortality of septic rats and play an important role in protecting organ function.

Objective To evaluate the effect of Shenfuhuang injection (SFH) on tissue and plasma TNF-? level and multiple organ dysfunction in septic rats. Method Wistar rats were subjected to sepsis by ceral ligation and puncture, then they were randomly divided into four groups, normal control, sham operation grop, septic group, SFH group. Animals were sacrificed at 2, 8, 24, 48 h. TNF-? level of lung, liver and plasma were measured. DAO activity was determined. Result TNF-? level of liver, lung and plasma were markedly increased at 2～8 h post-CLP compared with sham operation group. In SFH group, TNF-? level decreased in different degrees. DAO activity was much lower in SFH group than in CLP group at 2, 8 h. Conclusion Early applying of SFH could markedly inhibit TNF-? level of vital organs and injury of intestine, thereby preventing the development of excessive inflammation response and subsequent multiple organ dysfunction syndrome associated with CLP-induced sepsis.

OBJECTIVEThis study aimed to evaluate the vascular endothelial growth factor (VEGF) expression and permeability of vascular endothelial cell under microvibration.

METHODSHuman umbilical vein endothelial cell (HUVEC) were cultured, randomly vibrated under low frequency of 0.2, 0.5, 2, 5 Hz, 30 min per day. The VEGF mRNA level was detected by Tagman probe real-time fluorescence quantitative polymerase chain reaction (PCR), and the VEGF protein expression level was detected by Western blot. The permeability of vascular endothelial cell was evaluated.

RESULTSCompared with the blank control group, the mRNA and protein expression level of VEGF were significantly increased under 0.2, 0.5 Hz thelial, and increase the permeability microvibration (P<0.05), and decreased under 2, 5 Hz microvibration (P<0.01). The vascular endothelial permeability in creased under 0.2, 0.5 Hz microvibration (P<0.01), whereas the permeability decreased under 2, 5 Hz microvibration (P<0.01).

CONCLUSION0.2-0.5 Hz microvibration can up-regulate the expression of VEGF mRNA and protein in vascular endothelial, and increase the permeability.

Objective To analyze mutations in the cathepsin C (CTSC) gene in a patient with Papillon-Lefèvre syndrome (PLS).Methods Clinical data were collected from a patient with PLS.Two milliliters of venous blood samples were obtained from the patient,his parents and 100 unrelated healthy controls separately.DNA was extracted from these blood samples,and PCR was performed to amplify all the 7 exons of the CTSC gene followed by direct DNA sequencing.Results Two heterozygous mutations were observed in the CTSC gene of the patient.One was a novel mutation c.824C ＞ T at position 824 in the exon 6,which resulted in a substitution of ACC (threonine) by ATC (isoleucine) at codon 275 (p.T275I).The other one was the mutation c.1040A ＞ G at position 1040 in the exon 7,causing the substitution of TAT (tyrosine) by TGT (cysteine) at codon 347 (p.Y347C).His father and mother carried the heterozygous mutation c.824C ＞ T and c.1040A ＞ G respectively.Neither of the two mutations was observed in the 100 healthy controls.Conclusions CTSC mutations are responsible for the clinical phenotype of PLS.Identification of the c.824C ＞ T mutation extends the spectrum of mutations in the CTSC gene and provides a basis for genetic diagnosis of PLS.

Objective To investigate the effect of azelastin nasal spray combined with desloratadine in the treatment of allergic rhinitis .Methods Two hundred patients with allergic rhinitis were selected .According to the digital meter method ,the patients were randomly divided into observation group and control group ,with 100 cases in each group .The control group was treated by azelastin nasal spray , the observation group was given azelastin nasal spray combined with desloratadine .The clinical effects of the two groups were compared .Results The effective rate of the observation group(96.00%) was higher than that of the control group (80.00%),the difference was statistically significant(χ2 =6.235,P<0.05).After treatment,the scores of runny nose,nasal itching,nasal congestion,sneezing and the inferior turbinate swelling in the observation group were (1.1 ±0.2) points,(1.2 ±0.7) points,(1.1 ± 0.3)points,(0.8 ±0.3) points,(0.9 ±0.2) points,respectively,which were significantly lower than those in the control group [(1.4 ±0.9)points,(1.9 ±0.6)points,(1.8 ±0.8)points,(1.7 ±0.7)points,(1.9 ±0.9)points] (t=5.154,5.226,5.154,5.226,5.011,all P<0.05).Conclusion Azelastin nasal spray combined with deslorata-dine tablets in the treatment of allergic rhinitis can quickly relieve the patients 'clinical symptoms,improve the effec-tive rate,and it is safe and worthy of clinical popularization and application .

BACKGROUND:Chlorfenapyr is used to kill insects that are resistant to organophosphorus insecticides.Chlorfenapyr poisoning has a high mortality rate and is difficult to treat.This article aims to review the mechanisms,clinical presentations,and treatment strategies for chlorfenapyr poisoning. DATA RESOURCES:We conducted a review of the literature using PubMed,Web of Science,and SpringerLink from their beginnings to the end of October 2023.The inclusion criteria were systematic reviews,clinical guidelines,retrospective studies,and case reports on chlorfenapyr poisoning that focused on its mechanisms,clinical presentations,and treatment strategies.The references in the included studies were also examined to identify additional sources. RESULTS:We included 57 studies in this review.Chlorfenapyr can be degraded into tralopyril,which is more toxic and reduces energy production by inhibiting the conversion of adenosine diphosphate to adenosine triphosphate.High fever and altered mental status are characteristic clinical presentations of chlorfenapyr poisoning.Once it occurs,respiratory failure occurs immediately,ultimately leading to cardiac arrest and death.Chlorfenapyr poisoning is difficult to treat,and there is no specific antidote. CONCLUSION:Chlorfenapyr is a new pyrrole pesticide.Although it has been identified as a moderately toxic pesticide by the World Health Organization(WHO),the mortality rate of poisoned patients is extremely high.There is no specific antidote for chlorfenapyr poisoning.Therefore,based on the literature review,future efforts to explore rapid and effective detoxification methods,reconstitute intracellular oxidative phosphorylation couplings,identify early biomarkers of chlorfenapyr poisoning,and block the conversion of chlorfenapyr to tralopyril may be helpful for emergency physicians in the diagnosis and treatment of this disease.
