Hepatic stellate cell (HSC) activation is closely associated with the progression of liver fibrosis.As an important component of the innate immune system,natural killer (NK) cells are enriched in the liver and play a key role in host defense against viral infection and tumor,and their anti-fibrotic effect has also been confirmed.NK cells can reduce liver fibrosis by killing early-activated or senescent HSCs or secreting interferon-γ.This article summarizes related research advances in recent years,and introduces the molecular immunological mechanism of NK cells in regulating HSCs and their potential anti-fibrotic effect based on the function and phenotype of NK cells and HSCs.

Objective To investigate the effect of high altitude aviation on the pressure and diameter of the trachea cannula cuff after injecting air or water. Methods In the circumstance 5 km height and 795 hPa cabin pressure, the air injected cuffs were divided into two groups, one was under the ground circumstance, the other was in the high altitude aviation environment. The volumes of injected air were 5 ml, 7 ml, 9 ml, 11 ml, 13 ml, 15 ml, 17 ml, and the cuff pressure and its diameter were measured. The water injected cuffs were also divided into two groups of ground and high altitude aviation environment. The volumes of injected water were 10 ml, 12 ml, 14 ml, 15 ml, 16 ml, and the cuff pressure and its diameter were measured. The results were compared between the ground circumstance and high altitude aviation environment. Results The diameter of injection air group versus under the ground circumstance group had the statistical significance (t=5.000-9.449, P<0.05), when the injection air was larger than 15 ml, the pressure effect had statistical significance (t=5.000, 8.000, P<0.05). Water injection group had not statistically significant. Different water volume injection had no effect on pressure and diameter (P>0.05), while different air volume injection had significant effect on pressure and diameter (F=5.132, 5.980, P<0.01). When the water volume was 10 ml, the cuff pressure was (24.00±4.62) cmH2O (1 cmH2O=0.098 kPa) , which was appropriate to the range of cuff pressure (20-30 cmH2O). Conclusions In high altitude aviation environment the trachea cannula cuff should adopt water injection, and the best water volume is about 10 ml.

Objective To investigate the diagnosis and treatment of the posterior fossa solid hemangioblastomas (PFSHs).Methods The data of 23 patients with PFSHs verified by surgery and pathology were analyzed retrospectively.Results Nineteen cases were diagnosed with PFSHs before surgery.Total tumor removal was achieved in 22 patients.No case died of operation.A follow-up time was 0.33 -9.00 (2.96 ±2.73) years,20 patients returned to work,1 patient had self-handling living,and 2 patients died.Conclusions MRI and digital subtraction angiography are major preoperatively diagnostic modalities for PFSHs.PFSHs is still a kind of challenging neoplasms.Applicating special microsurgical technique and improving the operative manipulation can improve the surgical efficacy.

Objective To investigate the effect of pretreatment with dexmedetomidine alone or in combination with sufentanil on myocardial ischemia-reperfusion (I/R) injury in rats.Methods Fifty healthy male Sprague-Dawley rats,weighing 250-300 g,were anesthetized with intraperitoneal pentobarbital sodium 60 mg/kg.Myocardial I/R was induced by occlusion of anterior descending branch of left coronary artery for 30 min followed by 120 min of reperfusion.The rats were then randomly divided into 5 groups (n =10 each):sham operation group (group S),group I/R,dexmedetomidine pretreatment group (group DP),sufentanil pretreatment group (group SP),and dexmedetomidine + sufentanil pretreatment group (group DS).In group S the anterior descending branch was only exposed but not ligated.Dexmedetomidine 0.5μg/kg and sufentanil 0.1μg/kg were injected intraperitoneally 30 min before ischemia in groups DP and SP,respectively.Dexmedetomidine 0.5 μg/kg and sufentanil 0.1 μg/kg were injected intraperitoneally 30 min bbefore ischemia in group DS.Arterial blood samples were collected at 120 min of reperfusion for determination of serum creatine kinase (CK) and lactic dehydrogenase (LDH)concentrations.The rats were sacrificed at 120 min of reperfusion and hearts were removed for microscopic examination.Myocardial infarct size was calculated.The malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in myocardial tissues were measured.Results Compared with group S,the serum CK and LDH concentrations were significantly increased,the myocardial infarct size was enlarged,and SOD activity was decreased in the other groups,MDA content was significantly increased in groups I/R,DP and SP (P ＜ 0.05 or 0.01).Compared with group I/R,the serum CK and LDH concentrations,MDA content and myocardial infarct size were significantly decreased,and SOD activity was increased in groups DP,SP and DS (P ＜ 0.05).Compared with group DS,the serum CK concentration was significantly increased,the myocardial infarct size was enlarged,and MDA content was increased in groups DP and SP,and LDH concentration was significantly increased and SOD activity was decreased in group DP (P ＜ 0.05).The pathological changes were significantly attenuated in groups DP and SP compared with group DS.Conclusion Dexmedetomidine pretreatment can reduce myocardial I/ R injury in rats,dexmedetomidine combined with sufentanil pretreatment provides better efficacy than either alone,and inhibition of lipid peroxidation is involved in the mechanism.

The radix,leaf,flower and bud of raw medicinal materials and extraction of total alkaloids of Aconitum kusnezoffii Reichb.were all involved in this investigation.All the compositions from the samples were analyzed through fourier transform infrared spectroscopy (FTIR) combined with second derivative IR spectroscopy and two-dimensional IR correlation spectroscopy (2D-IR).It was found that the spectra of raw medicinal materials showed that the radix of A.kusnezoffii Reichb.featuring a large quantity of starch was the same as starch with the characteristic peaks at 1,155,1,070 and 1,019.The leaf,flower and bud contained the similar aromatic hydrocarbons (1,600),glycosides (1,050-1,070),while lipids were not clear.The characteristic peaks of the buds,flowers and leaves were all at 1,595 cm-1 (vibration of phenyl framework) and 1,262 cm-1 (=C-O).Therefore,it was suggested that the common compound of the three parts be diterpenoid alkaloids.Second derivative IR spectroscopy showed that the characteristic peaks of radix was stronger than those of the flower,leaf and bud at 1,712 cm-1 (C=O),which proved that the quantity of characteristic peaks in the radix was larger than those in the flower,leaf and bud.In addition,six autopeaks at 1,745,1,650,1,560 (the most strong),1,465,1,400,1,300 were detected from the radix.The similar autopeaks at 1,745,1,650,1,560 (the most strong),1,465,1,400,1,300 were found in the leaf,bud and flower.In conclusion,it was demonstrated that the macro-fingerprint infrared spectroscopic identification method provided a large quantity of the comprehensive information and entirely grasped the quality of A.kusnezoffii Reichb.Besides,FTIR and 2D-IR provided massive information of the integral structures of the radix,leaf,flower and bud of A.kusnezoffii Reichb.and verified the differences between the four parts of the herb in physical structure and the contents,laying a foundation for further systematic work.

The antifungal mechanism of the TS67(Penicillum sp.) producing bioactive metabolites was investigated in this paper. The test indicated that mycelia growth, spores forming and spores germination of Bipolaris maydis and Fusarium oxysporum can be inhibitied by metabolites, after 50% fermentation broth acting 120 hours, the inhibition rate of hyphal growth can reach about 77.78%, 70.30%, the inhibition rate of spores forming also arrived at 58.8%, 73.5%; under 50% fermentation broth acting 12 hours, the inhibition rate of spores germination were up to 78.3%, 62.0%, the mycelia under activity metabolites conditoins also showed surface nodulation and growing point expanding irregularly, protoplasmic condesing, etc. Based on all these results, we may draw a conclusion that activity metabolites maybe target at fungal cell wall.

OBJECTIVE:To analyze the differences of drug instructions between hospital directory and OTC standard model in-structions,and to provide reference for enhancing instruction management and reducing the safety risk of clinical drug use. METH-ODS:1 324 drugs of hospital directory in a hospital in 2014 were compared with OTC directory from CFDA websites. The instruc-tion of drug types included in OTC directory were compared OTC model instruction. According to the degree of risks which the dif-ferences may bring,differences were divided into four levels for analysis as negligible,general,important and severe. RESULTS:244 drugs belonged to OTC,of which 32.38%were different from standard model instructions. The four risk levels rates of negligi-ble,general,important and severe accounted for 29.11%,34.18%,7.59% and 29.11%,respectively. Among important risk,the difference of“indication limit”occupied the highest proportion,being 50.00%. Among severe risk,the difference of“forbidden for special disease”and“forbidden for pregnant women”accounted for 43.48% and 39.13%. CONCLUSIONS:There are problems, such as the absence of important medication information,statement conflicts. The hospital and administration departments should en-hance the standard management of drug instruction to guarantee safe and rational drug use in the clinic.
