Objective The paper analyzes the operating patterns of the outpatient process and identifies the links needing reengineering so as to provide scientific basis for the optimal allocation of outpatient resources and process reengineering and prove the rationality and feasibility of using the queuing theory. Methods Using the methods of the queuing theory, the service time and the patients' arrival time at such service links as registration, billing and accounting, internal medicine, and gynecology in the outpatient department of a certain hospital were measured and the operational indexes at various links such as service intensity, average queuing length, average queuing time, average stay, probability of the service desks being idle, and the probability of the patients having to wait were calculated so as to estimate the rational number of service desks and the optimal value of the sum of the cost of waiting and the cost of service. Results Registration, billing and accounting , service intensity in internal medicine, personnel allocation, and queuing time were basically rational in the outpatient department of the hospital surveyed. One more physician should be added to the gynecology department so as to improve efficiency and reduce patients' waiting time and queuing length. There was currently a shortage of medical staff in the hospital. The cost of hospital input was moderate while the cost of waiting was on the high side. Conclusion It is rational and feasible to evaluate the efficiency of the outpatient process with the methods of the queuing theory. The method deserves to be spread.

Objective To study atrioventricular conduction during right coronary artery infarction and its correlation with sympathetic nerve.Method AIMI model by ligating the fight coronary artery of denervated autonomic nervous cats was used.The A,H and V-wave were measured from the His electrode by template matching.The AA,AH,HV intervals with and without sympathetic nerve stimulation were measured respectivelv.Results The decreased percentage of AH intervals was (7±5)% vs.(14±5)% (without pacing) and (12±2)% vs.(23±7)% (with pacing) respectively in ischemia and normal after sympathetic nerve stimulation,and the decreasing amplitude were 50% and 48% respectively.Conclusion The regulating function of sympathetic nerve on atrioventricular conduction decreased after ischemia related to the right coronary artery.This decrease may be one of the mechanisms that lead to atrioventficular block after acute inferior myocardial infarction.

OBJECTIVE:
To investigate the genetic polymorphisms of 21 autosomal STR loci of Fujian Han population and evaluate the forensic application value of GlobalFiler Express kit.
METHODS:
Amplified with GlobalFiler Express kit, DNA samples were obtained from 741 unrelated individuals of Fujian Han population. The population genetics parameters of 21 autosomal STR loci were calculated.
RESULTS:
The 21 autosomal STR loci were found to be no deviation from Hardy-Weinberg equilibration (P > 0.05) and relatively abundant in high polymorphism. Heterozygosity ranged from 0.589 to 0.914, power of discrimination ranged from 0.754 to 0.992, polymorphic information content ranged from 0.520 to 0.940, and power of exclusion ranged from 0.278 to 0.825. The SE33 locus was the highest degree in polymorphism.
CONCLUSION
The 21 STR loci of GlobalFiler Express kit have high value in discrimination power and can be useful in personal identification and paternity test in Fujian Han population.

BACKGROUNDChoroidal melanoma is the most common intraocular malignant tumor in adults. It threatens not only the visual function but also the patient's life. Therefore, it is important to find a non-traumatic, quantitative and repetitive diagnostic method. This study investigated the value of quantitative analysis of contrast-enhanced ultrasound (CEUS) in the diagnosis of choroidal melanoma.
METHODSCEUS were performed in 51 cases of choroidal melanoma, which were diagnosed either pathologically or clinically and in 14 cases of choroidal hemangioma. The characteristics of the time-intensity curve of the contrast agent were analyzed. For the quantitative analysis, the following parameters of the contrast agent in the lesion were included: rising time (RT), time to peak (TTP), maximum intensity (MI) and the mean transit time (MTT).
RESULTSChoroidal melanoma had the following characteristics on CEUS: Choroidal lesions were completely filled with contrast agent. The typical filling pattern was centripetal, with the peripheral of the choroidal lesion filled with the contrast agent first and then the center of the lesion. In some cases, areas with contrast agent filling defect were observed in the lesions. The contrast agent filled the lesion slower than the normal eye and orbital tissue but faded faster in the lesion. Quantitative analysis showed that in choroidal melanoma, MI of contrast agent (191.31% ± 146.90%) was significantly more than that of the normal tissue (100.00% ± 0.00%) (P < 0.05) and MTT ((63.56 ± 26.04) seconds) was significantly less than that of the normal tissue ((149.87 ± 182.68) seconds) (P < 0.05). TTP (22.80 ± 9.85) was less than that of the normal tissue ((29.57 ± 24.76) seconds) and RT ((18.52 ± 7.09) seconds) was less than that of the normal tissue ((26.45 ± 21.83) seconds). Both the differences of TTP and RT were not statistically significant though. Logistic regression showed that to predict choroidal melanoma and choroidal hemangioma with MI and MTT, the sensitivity was 90.5% and the specific degrees was 85.7%.
CONCLUSIONSCEUS is a new method to diagnose tumors in the eye. Choroidal melanoma may be diagnosed objectively and accurately by combining the graphic characteristics on CEUS and the time-intensity curve quantitative analysis.

Objective:To compare the effectiveness of fire needle versus Western medicine in the treatment of herpes zoster. Methods:Randomized controlled trials comparing fire needle with Western medicine in the treatment of herpes zoster were identified using 8 databases. A meta-analysis was performed using RevMan 5.3 software. Results:Eight trials involving 569 patients were included in this meta-analysis, and the results showed that fire needle was superior to Western medicine comparing the effective rate [risk ratio (RR)=1.13, 95% confidence interval (CI): 1.06 to 1.20;P=0.0002], the visual analog scale (VAS) score [mean difference(MD)=–7.95, 95% CI: –10.71 to –5.20;P<0.00001], time of pain disappearance (MD=–7.61, 95%CI: –9.38 to –5.84;P<0.00001), time of blister-stop (MD=–1.34, 95%CI: –1.51 to –1.18;P<0.00001), time of crusted scab (MD=–2.92, 95%CI: –3.62 to –2.23;P<0.00001), and time of scab off (MD=–4.64, 95%CI: –5.83 to –3.46;P<0.00001). In addition, a significantly lower incidence of postherpetic neuralgia was found in the fire needle group in 30 d (RR=0.23, 95%CI: 0.11 to 0.51;P=0.0002) and 60 d (RR=0.33, 95%CI: 0.12 to 0.91; P=0.03) after treatment. Conclusion:Fire needle has a favorable effect in increasing the effective rate, relieving pain, recovering skin lesions and decreasing incidence of postherpetic neuralgia in the treatment of herpes zoster. However, considering the limitations in this study, the findings should be interpreted cautiously.

Objective To study the clinical characteristics and curative effects of pancreatic cystade- nocarcinoma in order to improve its diagnostic and therapeutic accuracy.Methods A retrospective analysis was done on the clinical materials of 13 cases of pancreatic cystadenocarcinoma hospitalized in Shanxi Cancer Hospital from 1990 to 2006.Results The preoperative diagnosis were as follows:pancreatic cystadenocarci- noma 6 cases,pancreatic cystadenoma 2 cases,pancreatic cancer 1 case,pancreatic pseudocyst 4 cases.The misdiagnosis rate was 53.8 %.Surgical operation was done on the 13 cases,and 10 of them were treated by radical operation.A 5-year follow-up was done on 6 still alive cases,and 1 of them lived over 11 years.3 cases were treated by palliative operation,and all of them died within 3 years.Conclusion Since there is no specific clinical manifestations of pancreatic cystadenocarcinoma,it is very difficult to get an accurate preop- erative diagnosis.Radical operation is the most effective therapeutic methods.
