We retrospectively analyzed 23 cases of histiocytic necrotizing lymphadenitis (HNL) admitted to our hospital as fever of unknown origin (FUO).Fever,lymphadenopathy and skin rash were the most common clinical manifestation.The major laboratory features included cytopenia,abnormal liver enzyme and elevated inflammatory markers.Three of the 23 cases were finally diagnosed as infectious disease,5 as autoimmune disease,while the left 15 remained as HNL during the follow-up.Four of the 15 HNL patients resolved spontaneously,while the other 11 relieved by steroid use.Two patients relapsed during the follow-up.HNL was one of the rare causes of FUO.Since it would be accompanied with infectious,autoimmune or malignant diseases,long follow-up is necessary.

Objective To analyse the causes of shunt obstructions after ventriculoperitoneal shunting for children hydrocephalus and their therapy. Methods Ventriculoperitoneal shuntings were done in 156 children with hydrocephalus, in 26 cases of them, the shunts were obstructed. Surgical interventions were performed, and causes of obstruction were found and corrected. Results There were eight kinds of obstructive causes in the ventricular catheters, three kinds in the peritoneal catheters. All obstructions were corrected surgically, 26 patients recovered soon without complications and mortality.Conclusion If the causes of ventriculoperitoneal shunt obstructions can be found and corrected in time, the prognosis of patients is good.

The developing process of thermal comfort was analyzed based on physiology and psychology and the relationship between thermal comfort and human health, environment was discussed in this paper.It suggested that the thermo-stable and thermo-comfortable environment, which might decrease body's adaptability to environment, were not necessarily good for human health. It might have some impacts on human's physiological and psychological adaptabilities also to live in the environment with a great difference between the indoor and outside temperature simultaneously and alternately.

Objective To investigate the thermostability of aristolochic acid Ⅰand the effect of the compatibility on aristolochic acid Ⅰ in Caulis Aristolochiae Manshuriensis decoction and to explore the detoxification mechanism of compatibility for aristolochic acid Ⅰ.Methods Analyzing the contents of aristolochic acid Ⅰ by HPLC in the single decoction of Caulis Aristolochiae Manshuriensis,the concoction of Caulis Aristolochiae Manshuriensis with Cortex Moutan,the residues of decocted Caulis Aristolochiae Manshuriensis and the residues of concocted Caulis Aristolochiae Manshuriensis with Cortex Moutan,respectively.Results Aristolochic acid Ⅰ decreased after heating in pure water,a new peak was found in HPLC spectra and supposed to be the derivate of aristolochic acid Ⅰ,which was also found in the decoction of Caulis Aristolochiae Manshuriensis.The content of aristolochic acid Ⅰ in the concoction of Cortex Moutan with Caulis Aristolochiae Manshuriensis is lower than that in the single Caulis Aristolochiae Manshuriensis decoction.Furthermore,the quantity of aristolochic acid Ⅰ in the residues of Caulis Aristolochiae Manshuriensis after concoction is lower than that in the residues of single Caulis Aristolochiae Manshuriensis decoction.Conclusion Aristolochic acid Ⅰ is unstable in decoction and a part of it was changed into another compound.The stripping of aristolochic acid Ⅰfrom Caulis Aristolochiae Manshuriensis is not inhibited when Cortex Moutan concocted with Caulis Aristolochiae Manshuriensis.It is the chemical reaction of aristolochic acid Ⅰ,which could decrease the toxicity in the decoction or concoction of Caulis Aristolochiae Manshuriensis.

To study the effects of fentanyl on the MAC of sevoflurane. Method: One hundred and sixteen patients were given continuous infusion of fentanyl with CACI-pump (computer-assisted continuous infusion)to maintain different target plasma concentrations (Ct), meanwhile inhaled sevoflurane. All patients were randomly divided into seven groups receiving sevoflurane in oxygen with fentanyl target plasma concentration of 0?g/L (n=16), 0.5?g/L(n=20), 1?g/L(n=18), 2?g/L(n=16), 3?g/L(n=18), 4?g/L(n= 14) or 6?g/L(n= 14). Plasma concentraion of fentanyl was measured with radioimmunoassay. MAC determination, in response to the stimulus of skin incision, was made using the "up-down" method and logistic regression. Result: The MAC of sevoflurane from group 1 to group 7 were 1.94%, 1.89%, 1.55%, 1.29%, 1.09%, 0.86% and 0.35% respectively. Conclusion: We verify the MAC of sevoflurane, which is reduced by increasing plasma fentanyl concentration.

Objective To study effect of etoricoxib on IL-1βand TNF-αin patients with gouty arthritis.Methods 86 patients with gouty arthritis from July 2014 to July 2016 in our hospital were selected, all patients were divided into study group and control group according to the treatment method with 43 cases in each group.The patients in the control group were treated with diclofenac sodium, the patients in the study group were treated with etoricoxib.The clinical symptoms, clinical treatment effects, VAS score, serum IL-1β, TNF-αlevels and adverse reactions were observed and compared between the two groups.Results The VAS score, the joint swelling score and the mobility limitation score of the study group were decreased than before treatment and significantly lower than those of the control group, the difference was statistically significant (P<0.05).The effective rate of the study group (95.35%) was significantly higher than that of the control group (79.07%), the difference was statistically significant(P<0.05).The levels of IL-1βand TNF-αin the two groups were significantly lower than before treatment and the levels of IL-1βand TNF-αin the study groups were significantly lower than those in the control group,the difference was statistically significant(P<0.05).The incidence of adverse reactions in the study group was lower than that in the control group, the difference was statistically significant(P<0.05).Conclusion The clinical efficacy of etoricoxib in treating patients with gouty arthritis is significant, which can effectively relieve the clinical symptoms, inhibit the expression of IL-1βand TNF-α, and the adverse reactions less.

OBJECTIVE:To study the antithrombotic effect of orientoside.METHODS:The effects of prophylactic oriento_side on the clotting time in vitro and the systemic clots dissolution of mice,the plasma prothrombin time(PT),the kaolin partial thromboplastin time(KPTT),the thrombin time(TT),and the platelet aggregation induced by ADP and the euglobulin lysis time (ELT)in rabbits were studied.RESULTS:As compared with the normal saline group,orientoside(1,2,and 4mg/kg)signi_ficantly prolonged the clotting time of mice in vitro,yet which had no significant influence on the systemic clots dissolution of mice;while orientoside(0.625,1.25 and 2.5 mg/kg)significantly prolonged the PT,KPTT and TT of rabbits,and significantly inhibited platelet aggregation of rabbits induced by ADP,yet which had no significant influence on the ELT of the rabbits.CONCLUSION:Orientoside can significantly inhibit the formation of thrombus.

Objective To observe the effects of the ethanol extract of thunberg fritillary leaf (EETFL) and the ethanol extract of thunberg fritillary flower (EETFF) on relieving cough, sputum elimination and relieving asthma. Methods The cough relieving effects of EETFL and EETFF were studied in mouse cough model caused by ammonia water and in guinea pig cough model caused by citric acid. The sputum elimination effects of EETFL and EETFF were researched by the observation of tracheal phenol red shedding in mice. The asthma relieving effects were tested by spraying method in guinea pigs. Results EETFL can obviously inhibit the incubation period and cough frequency of the model mice and guinea pigs induced by ammonia water and citric acid (P<0.05), and significantly improve the tracheal phenol red excretion volume in mice (P<0.05), and obviously prolong the incubation period of asthma (P<0.05). EETFF can obviously inhibit the incubation period and cough frequency of the model mice and guinea pigs induced by ammonia water and citric acid (P<0.05), and significantly improve the tracheal phenol red excretion volume in mice (P<0.05), but EETFF couldn’t prolong the incubation period of asthma evidently. Conclusion EETFL has obvious activity of relieving cough, eliminating phlegm and relieving asthma. EETFF has obvious activity of relieving cough and eliminating phlegm, but EETFF has no anti-asthmatic activity under the current dose.
