OBJECTIVETo analysis deacclimatization symptom scores of 159 youth from Karakoram and Tibet Ali area, and provide the basis for the development of relevant prevention and control measures.
METHODSUsing the method of epidemiological symptoms questionnaire, 18 symptoms of 190 youth who returned to the plain area from the different plateau were investigated. The symptom scores of different altitude, age, the time of staying, different units, continuous or intermittent stage and education were surveyed.
RESULTSDeacclimatization symptom scores among 5,000 meter groups were significantly higher than those of 4,300 meter and 3,700 meter group (P < 0.05, P < 0.01). There was no significant difference between the 4,300 meter group and the 3,700 meter group (P > 0.05). There were significant differences among the stayed personnel (different age, position, unit, education, time, continuous or intermittent) (P < 0.01). There was significant difference between the continuous defended the group and intermittent group (P < 0.01).
CONCLUSIONDeacclimatization symptom scores were related to the plateau exposure time, altitude, workload, plateau continued exposure. The older, the longer exposure, the higher altitude, the greater workload at plateau were showed higher deacclimatization symptom score.

Objective To evaluate the clinical training outcomes from two clinical practice modes for undergraduate students. Methods Total two grades 2009 and 2010,150 undergraduate students were randomly divided into two groups: 69 students in group A and 81 students in group B. The synthetic teaching mode was applied in group A,and group B received the traditional teaching mode. The Objective Structure Clinical Examination (OSCE)and a written comprehensive examination were used to evaluate the training outcomes by T test analyzed by SPSS 17.0(α= 0.05). Results The theoretical level of 2009 grade students was better than that of 2010 grade (P < 0.05). The clinical practice skills of the two groups had no significant difference(P > 0.05). There were no significant differences between two groups in theoretical and clinical training(P > 0.05). Comparing with the 2010 grade,the theoretical level of the 2009 was better,but the clinical skill level was weaker. Conclusion Synthetic teaching mode and traditional teaching mode both achieved good outcomes. In order to obtain better comprehensive progresses,the two teaching modes need to be combined. The orientation by following the requirements of oral practicing qualification examination may enhance the clinical skills of the students.

OBJECTIVETo explore the mechanisms of Qianjing Decoction in the treatment of oligoasthenospermia (OAS).
METHODSWe randomly divided 100 SPF male rats into five groups of equal number: normal, model, Huangjingzanyu, levocarnitine, and Qiangjing. OAS models were established in the animals followed by intragastrical administration of normal saline, ornidazole, Huangjingzanyu Capsules (200 mg per kg body weight per day), levocarnitine (100 mg per kg body weight per day), and Qianjing Decoction (10 g per kg body weight per day), respectively, qd, for 4 successive weeks. Then, we detected the concentration and motility of the epididymal sperm, obtained the contents of superoxide dismutase (SOD), malonaldehyde (MDA), glutathione peroxidase (GSH-Px), lactate dehydrogenase (LDH), α-glucosidase, and fructose in the epididymis, and determined the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and succinate dehydrogenase (SDH) in the epididymal tissue of the rats by real-time PCR.
RESULTSThe concentration and motility of the epididymal sperm in the model, Huangjingzanyu, levocarnitine, and Qianging groups were (35.34 ± 4.22) x 10(6)/ml and (40.04 ± 7.05)%, (48.12 ± 5.56) x 10(6)/ml and (62.46 ± 7.12)%, (47.14 ± 4.87) x 10(6)/ml and (63.23 ± 6.34)%, and (50.25 ± 5.08) x 10(6)/ml and (66.34 ± 7.58)%, respectively, all significantly lower than in the normal group ([53.05 ± 4.55] x 10(6)/ml and [70.20 ± 8.54]%) (P < 0.05), but remarkably higher in the Huangjingzanyu, levocarnitine, and Qiangjing groups than in the model rats (P < 0.05). Compared with the thinned epididymal lumen walls, decreased sperm count, and disorderly and loose arrangement of the lumens in the OAS models, the rats in the Huangjingzanyu, levocarnitine, and Qiangjing groups showed evidently thicker epididymal lumen walls, with the lumens full of sperm cells and arranged regularly and compactly, similar to those of the normal rats. The levels of SOD and GSH-Px were significantly lower but that of MDA markedly higher in the model rats ([84.12 ± 23.25], [10.56 ± 3.02], and [14.04 ± 2.06] nmol/mg) than in the normal group ([110.04 ± 19.56], [17.25 ± 3.56], and [8.87 ± 1.35] nmol/mg) (P < 0.05), while the former two indexes remarkably higher and the latter one significantly lower in the animals treated with Qiangjing Decoction ([120.56 ± 23.68], [16.34 ± 3.12], and [8.45 ± 1.56] nmol/mg), Huangjingzanyu Capsules ([115.34 ± 21.35], [15.23 ± 3.67], and [8.33 ± 1.54] nmol/mg), and levocarnitine ([116.67 ± 22.67], [15.35 ± 3.45], and [8.05 ± 1.78] nmol/mg) than in the models (P < 0.05). The levels of fructose, LDH and α-glucosidase were decreased markedly in the OAS models ([100.22 ± 12.12] mg/[ ml x g], [322 ± 46.13] U/[ ml x g], and [10.48 ± 2.33] U/[ml x g]) as compared with the normal rats ([128.12 ± 13.45] mg/[ml x g], [428 ± 35.12] U/[ml x g], and [15.34 ± 3.12] U/[ ml x g]) (P < 0.05), remarkably higher in the rats treated with Qiangjing ([130.23 ± 13.67] mg/[ml x g] [455 ± 51.50] U/[ml x g], and [18.56 ± 4.67] U/[ml x g]), Huangjingzanyu ([124.16 ± 14.02] mg/[ml x g], [ 419 ± 43.14] U/[ml x g], and [17.64 ± 4.08] U/[ml x g]), and levocarnitine ([123.34 ± 14.02] mg/[ml x g], [430 ± 31.80] U/ [ml x g], and [16.85 ± 5.55] U/[ml x g]) than in the models (P < 0.05). The Nrf2 mRNA expression was significantly reduced in the models as compared with the normal rats (P < 0.05) but remarkably increased in the Huangingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05). The SDH mRNA expression was significantly lower in the model than in the normal rats (P < 0.05) but markedly elevated in the Huangjingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05), remarkably higher in the Qiangjing than in the Huangjingzanyu group (P < 0.05).
CONCLUSIONOrnidazole induces OAS in rats, which is closely associated with excessive oxidation and energy metabolism dysfunction. Qiangjing Decoction can improve and even reverse ornidazole-induced OAS in rats as well as improve the ultrastructure of their testicular and epididymal tissues. Antioxidation and improvement of energy metabolism are probably the action mechanisms of Qiangjing Decoction in the treatment of OAS.

Objective To explore the value of 11C-choline PET/CT in patients with hepatic spaceoccupying lesions that have an indeterminate diagnosis by 18F-fluorodeoxyglucose (FDG) PET/CT. Methods A total of 25 liver masses in 20 patients with an indeterminate diagnosis based on 18F-FDG PET/CT were enrolled. Regional 11C-choline PET/CT scan was performed in all of the patients. Lesions with intense 11C-choline uptake were considered as positive. The semiquantitative maximum standardized uptake value(SUVmax) was measured and the tumor-to-liver (T/L) radioactivity ratio was calculated. The Mann-Whitney test,Kruskal-Wallis test and crosstabs x2-test were performed by using SPSS version 11.5. Results Of the 25 lesions,21 were proven to be hepatocellular carcinomas (HCC),3 hemangiomas,and 1 parasitic granuloma. The sensitivity of 11C-choline PET/CT for the detection of HCC was 66.7% (14/21). 11C-choline PET/CT had a higher sensitivity for well differentiated HCC than moderately and poorly differentiated HCC on a patient basis (8/9 vs 2/5,respectively). There were significant differences of 11C-choline T/L ratios between the HCC positive group,HCC negative group and benign lesion group ( 1.70 ± 0.35,0.86 ± 0.15,and 0.36 ± 0.18,x2 = 19.00,P <0.01 ). The lesion size and alphafetoprotein (AFP) level between the HCC positive and negative groups had no significant difference respectively ( Mann Whitney U = 39.00,P >0.05,and U=16.00,P>0.05,respectively). Conclusions 11C-choline is complementary to 18F-FDG PET/CT for the detection of HCC,especially for well differentiated HCC.
