Objective:To analyze the causes of microbial contamination in methadone hydrochloride oral solution used for the ma-intenance treatment of heroin addict in Guangxi and propose the relative countermeasures. Methods:The samples of methadone hydro-chloride oral solution were obtained from 10 maintenance treatment clinics, and then the microbial limit test and identification were per-formed,the content of preservative was detected and the relationship between the preservative content and microbial contamination was studied. Results:The total number of aerobe in the samples of methadone hydrochloride oral solution from the 10 clinics was all over the standard limit value of 100 cfu·ml-1 ,and the main contaminating germ was Burkholderia cepacia. The contents of sorbic acid were 78. 2％-98. 3％,the four batches with the lowest concentration of preservative were detected with higher total number of aerobe. Con-clusion:The microbial contamination in methadone hydrochloride oral solution from the 10 maintenance treatment clinics is severe,and the environment of medicine packaging, content of preservatives, packaging machine and storage conditions are the primary causes for the microbial contamination. To ensure drug quality safety, it is suggested that the environment cleanliness of medicine packaging be improved, suitable content of preservatives be added, packaging machine be clean, the products be stored in shade and the quality be tested regularly.

Objective To expolore the changes of coagulation index in newborns of different age and its clinical significance. Methods We studied 129 newborn infants without complication admitted to the neonatal department in an all-around hospital in Gnangzhou from January to December in 2005. These neonates were divided into two groups, including 63 cases of full-term infants and 66 cases of premature infants. Prothrombin time (PT), activated partial prothrombin time (APTT), Fibrinogen (Fg), thrombin time (TT), D-dimer (D-D) of these newborn infants were assayed on the first day, the third day and the tenth day. Results In the postnatal three periods of time, there was no difference in PT and D-dimer between two groups(P >0.05), but APTT and TT in premature infants were higher than that in full-term infants( P < 0.05), and Fg in premature infants were lower than that of full-term irfants(P<0.05). PT,APTT, TT,Ddimer were in decrease tendency and Fg increased as age increased( P < 0.05 ). Conclusion Geststional age and age had effect on coagulation index in newborn infants, and both can provide clinical references to clinical diagnosis and therapy.

Objective To study the clinical features and treatment of horizontal canal benign paroxysmal positional vertigo (HC-BPPV).Methods The clinical features of 27 patients with HC-BPPV and the treatment results with otolith repositioning maneuver of Barbecue rotation were analyzed retrospectively.Results All the patients with HC-BPPV had vertigo attack and this kind of vertigo attack presented with some characters such as brief, positioning, latency and no fatigability. Geotropic nystagmus was seen in 21 patients and apogeotropic nystagmus was seen in 6 patients when head was turned to either side in supine position. After Barbecue rotation, all symptoms disappeared in patients with geotropic nystagmus and did not change in patients with apogeotropic nystagmus.Conclusions The diagnosis of HC-BPPV is based on typical clinical features and test of turning head to either side in supine position. Geotropic nystagmus is associated with canalithiasis and apogeotropic nystagmus is associated with cupulolithiasis, and the therapy of Barbecue rotation is very effective to HC-BPPV patients with geotropic nystagmus.

It was reported that Os-thole(Ost) was isolated from the fruits of Cnidium monnieri(L. ) Cusson, possessesanti - arrhythmic action and depressed the aortic pressure action in animal studies. Its calcium -antagonistic effects were studied on the isolated rabbit aortic strips.Ost shifted the dose response curves for NE, CaCl2 and KC1 nonparallelly to the right, and depressed their maximal response; pD2' value is 3. 16, 4. 28 and 4. 39 respectively. It produced neither ?- a-drenoceptic stimulating nor ? - adreno-ceptic blocking effects. At the concentration of 100 ?mol ? L-1, Ost significantly inhibited the intra cellular Ca2+ dependent component of NE - induced contraction of the aortic strips, however, it didn't in-hibit the extra cellular Ca2+ dependent component of NE - induced contraction of the aortic strips, These results indicated that Ost produced relaxation on vascular smooth muscle might result from its antagonistic effect to Ca2+ and mainly blocked calcium influx through PDC, and the mode of its anta -gonism is similar to that of verapamil.

Osthole, the coumarin isolated from the fruits of Cnidum monnieri (L.) Cusson. The effects of osthole on the physiological properties in isolated auricle of guinea pig were studied. It possesses dose—dependent negative inotropic effects, the BaCl_2 inducing automaticity was inhibited, and the functional refractory period (FRP) was prolonged, and the frequence of sinoatrial node was slowed The negative inotropism and automatism suggest that sothole mey be antagonis tic to Ca~(2+), while the decrease of excitability and the prolongation of FRP indicate that it may be due to its inhibition on Na~+ current. The decrease of automaticity and excitability and prolongation of FRP are thought to be its antiarrhythmic action.

Objective To analyze the prognostic value of baseline serum free light chain (sFLC) in light-chain (AL) cardiac amyloidosis.Methods Twenty-seven patients with AL cardiac amyloidosis were retrospectively reviewed from January 2014 to January 2015.sFLC was measured by immuoturbidimetric assay.Baseline characteristics,echocardiographic parameters and electrocardiogram data were analyzed.According to the median baseline dFLC (involved sFLC minus uninvolved sFLC),patients were categorized into either the low dFLC(≤307mg/L) or the high dFLC group (＞307mg/L).Results More subjects in the high dFLC group with early/late diastolic mitral velocity ratio (E/A ratio) over 2 (71.4％ vs 30.8％,P =0.035),and subjects in this group had a shorter median survival time than those in the low dFLC group (3 months vs 17 months,P =0.004).A similar phenomenon for median survival time was observed when the subjects were redivided either by a new cut-off value of 180mg/L for dFLC (low dFLC group:17 months;high dFLC group:4 months,P =0.014) or a κ/λ ratio,in which subjects with κ type sFLC-ratio ≤ 19.6 and λ type sFLC-ratio ＞0.065 were in the low sFLC-ratio group (17 months) and those with κ type sFLC-ratio ＞ 19.6 and λ type sFLC-ratio ≤0.065 were in the high sFLC-ratio group (4 months,P=0.023).In multivariate analysis,dFLC and New York Heart Association (NYHA) classification of cardiac function were two risk factors associated with all-cause mortality in patients,among which the hazard ratio for higher dFLC was 4.28 (95％ CI 1.55-11.8,P =0.005).Conclusion The level of sFLC could be a marker for the prognosis of AL cardiac amyloidosis.
