Objective To investigate effect of different anesthesia on cesarean section perioperative coagula-tion function and D -dimer,to provide a reference for clinical treatment.Methods 120 cases of cesarean section patients were selected,according to the anesthesia they were divided into observation group and control group.Obser-vation group (70 cases) used combined spinal epidural anesthesia,the control group(50 cases) used epidural anes-thesia.The prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time (TT),fiber clinical indicators fibrinogen (Fbg),DD,analgesia and its complications were compared between the two groups.Results Before surgery,PT,APTT,TT,Fbg had no statistically significant differences between the two groups (P >0.05).6h, 24h after operation, PT,APTT,TT of the observation group were (13.23 ±1.86) s,(31.18 ±5.94) s,(15.52 ± 2.55)s;(12.85 ±1.94)s,(29.74 ±5.52)s,(14.68 ±3.15)s,which were lower than the control group,the differ-ences were statistically significant (t =3.294,4.546,4.143,3.656,3.435,3.115,all P <0.05).6h after operation, Fbg of the observation group was (3.17 ±0.48)g/L,which was lower than the control group,the difference was statis-tically significant (t =3.656,P <0.05);D -D of the observation group before surgery,immediately after surgery,24h after surgery were (0.28 ±0.04)mg/L,0.04mg/L,(0.33 ±0.07)mg/L,(0.33 ±0.07)mg/L,compared with the control group had no statistically significant differences (P >0.05).In the observation group,the incidence rates of pain level 2,3 were 41.43%,30.00%,compared to the control group showed no significant difference (P >0.05). Deep vein thrombosis was not found in the observation group,the control group confirmed one case of femoral vein thrombosis,the incidence of venous thrombosis in the two groups showed no significant difference ( P >0.05). Conclusion Combined spinal epidural anesthesia,epidural anesthesia can both prevent cesarean section patients from perioperative hypercoagulable state,reduce the incidence of thrombotic complications,epidural anesthesia is the preferred method.

Objective To investigate different fentanyl medication methods on propofol intravenous anesthe-sia painless abortion,to provide a reference for clinical treatment.Methods 1 20 patients undergoing painless abor-tion were selected,according to the random number table they were divided into Ciliao point group,subcutaneous group,intravenous injection group,40 cases in each group.Intravenous injection group used intravenous anesthetic propofol,Ciliao point group used Ciliao hole injection anesthesia,subcutaneous group used fentanyl anesthesia subcu-taneous injection.The anesthesia,analgesia and other clinical indicators of complications were compared among the three groups.Results The anesthesia excellent and good rate of Ciliao point group was 97.50%,which was higher than the subcutaneous group,intravenous injection group,the differences were significant(χ2 =4.1 32,3.894,all P <0.05).MAP,HR,SpO2 among three groups showed no statistical differences (P >0.05).Postoperative 4h,8h,VAS scores of Ciliao point group were (2.32 ±0.56)points,(1 .1 3 ±0.23)points,which were lower than those in the subcutaneous group,intravenous injection group,the differences were significant (t =8.656,8.843,6.587,6.335,all P <0.05).The propofol use times,the amount of Ciliao point group were (1 .1 4 ±0.1 4),(1 1 6.37 ±1 4.35)mg respectively,which were less than those in the subcutaneous group,intravenous injection group,the differences were significant (t =6.645,5.587,6.1 32,5.854,all P <0.05).The incidence rate of adverse reaction of Ciliao point group was 2.50%,which of the subcutaneous group was 20.00%,which of the intravenous group was 25.00%,the differences were statistically significant (χ2 =6.596,7.454,all P <0.05).Conclusion Fentanyl uased at Ciliao point can enhance the clinical effect of anesthesia with less postoperative pain and reduce incidence of adverse reac-tions,it is worthy of clinical application.

Objective: To investigate the levels of lanthanum, cerium, praseodymium, and neodymium in the blood, urine, and hair samples from residents in the rare earth mining area of a city in China, and to provide a scientific basis for the control of rare earth pollution and the protection of population health. Methods: A total of 147 residents who had lived in the rare earth mining area of a city for a long time were selected as the exposure group, and 108 residents in Guyang County of this city who lived 91 km away from the rare earth mining area were selected as the control group. Blood, urine, and hair samples were collected from the residents in both groups. Inductively coupled plasma mass spectrometry was used to determine the content of lanthanum, cerium, praseodymium, and neodymium in blood, urine, and hair samples. Results: In the exposure group, the median levels of lanthanum, cerium, praseodymium, and neodymium were 0.854, 1.724, 0.132, and 0.839 μg/L, respectively, in blood samples, 0.420, 0.920, 0.055, and 0.337 μg/L, respectively, in urine samples, and 0.052, 0.106, 0.012, and 0.045 μg/g, respectively, in hair samples. The exposure group had significantly higher levels of the four rare earth elements in blood, urine, and hair samples than the control group (P<0.01) . Conclusion The residents in the rare earth mining area of this city have higher content of lanthanum, cerium, praseodymium, and neodymium in blood, urine, and hair than those in the non-mining area; the content of cerium is highest, followed by lanthanum, neodymium, and praseodymium.

OBJECTIVETo explore the species, distributing and resource of Paris genus plants in Xishuangbanna area of Yunnan province.

METHODTwo steps, talking with the folk doctors and field survey, were employed to explore the resource status of Paris plants. Twenty six villages and towns, which are at an elevation of 500 m to 2000 m, were investigated.

RESULTA total of 214 specimens were collected and identified according to morphological characteristics. All investigated spots had Paris genus resources distribution but there always had a small Paris population less than 20. The Paris genus is an understory plants which lives always in a specific environment beside creek in hill valley and with many commensal plants such as bamboo and broadleaf. Three species of Paris, P. polyphylla var. yunnanensis, P. polyphylla var. chinensis, and P. vietnamensis were collected and identified.

CONCLUSIONParis genus resources declined rapidly in recent year, particular the P. polyphylla var. yunnanensis. Developing the breeding and cultivation technologies and enhancing the resources protection are needed urgently.
