The anatomical and functional details of the anterior cruciate ligament (ACL) of the knee joint were studied on 55 normal cadaver knees of adults.ACL is made up of multiple fascicles, the basic unit of which is collagen. It is attached to the medial surface of the lateral femoral condyle and front of the anterior tibial spine. ACL is narrow in the middle and fans out at the attachments. The fascicles of ACL have been summarily divided into two groups: the anterior medial portion (AMP) and the posterior lateral portion(PLP). The tension of AMP is different from that of PLP during movement of the knee. ACL restricts the anterior drawer sign, and the internal and external rotation of the knee. AMP acts with the knee in flexion and PLP in extension. ACL restricts hyperextension, too. The function of ACL is related to its morpholcgical structure and the anatomy of the attachments. Rupture of ACL may result in instability of the knee, and injuries to the different components of ACL may produce different signs.

By comparing three cultivation techniques of Astragalus mongholicus, i. e. direct seeding, furrow erectplanting and furrow flat planting, it was found that furrow flat planting is the optimum technique. Its yield onplain ground was 1. 26kg/m' and 0. 96kg/m_2 on mountainous area- Root of the plant was longer, thicker andheavier than that produced hy other cultivation techniqlles. Its input/output ratio was l s l2' 94 on plaingrounfl and l: 9. 95 on n1ollntainous area. Therefore,it can be considered as a scientifically justifiable,economically technique for the cultivation of A. mongholicus on both plain ground and mountainous regions.

Objective To observe the treatment effect of acupoint massage and auricular point sticking of cowherb seeds on blood pressure of hypertensive patients.Methods 100 cases of hypertensive patients were randomly divided into the observation group and the control group,50 cases in each.The observation group was given routine application of antihyportensive drags combined with acupoint massage and auricular point sticking of cowherb seeds.The control group received routine drug therapy.The blood pressure changes were compared between the two groups before and after treatment.Results The systolic blood pressure and diastolic blood pressure of both groups were lower after treatment compared with those before treatment.The total effective rate of blood pressure control was 98％ in the observation group,88％ in the control group,which showed no significant difference.Symptom control results showed that the total effective rate of the observation group was higher than that of the control group.Conclusions Acupoint massage and auricular point sticking of cowherb seeds in hypertensive patients can be an auxiliary pressure relief means,it can not only effectively lower blood pressure,but show good effect in alleviation of headache,vertigo,irritability.

Objective To investigate the influence of fixed nurse specialists triage to improve the quality of patient triage.Methods Nurses were divided into the fixed nurse specialist triage group (group A) and the out-patient department rotation nursing group (group B),respectively,each group was responsible for triage of patients in clinic of medical department for five days.Then the number of two subdiagnosis error and the average daily working overtime for doctors were compared.Results A total of 3806 patients were in clinic triage in group A,165 patients had triage error.A total of 3812 patients were in clinic triage in group B,308 patients had triage error.The average daily working overtime of doctors in group A was(5.24 ± 0.37)hours,and(8.16 ± 0.58) hours in group B.The errors in triage and working overtime of doctors had significant differences between two groups.Conclusions Fixed specialist nurse triage can significantly improve the quality of patient triage in clinic.

Objective:To investigate the effects of acupoint massage on cognitive function and sleep quality in elderly patients with hypertension. Methods:A total of 68 elderly patients with hypertension were enrolled, and their ages were all over 60 years old. They were divided into a control group and a treatment group by simple random method, with 34 cases in each group. Patients in the control group were treated by routine psychological health guidance and sleep knowledge education, while patients in the treatment group were treated by acupoint massage on the base of the interventions given to the control group. Both of their treatment courses were 3 months. Pittsburgh sleep quality index (PSQI) scores and mini-mental state examination (MMSE) scores before and after treatment were recorded and compared. Results:Two groups’ PSQI scores before treatment had no significant difference (P>0.05). After 3 months of treatment, their PSQI scores were statistically different (P<0.05). There was also no between-group statistical difference in MMSE score before treatment (P>0.05), but there was a significant difference after treatment (P<0.05). Conclusion:Acupoint massage for elderly patients with primary hypertension can improve their sleep quality and enhance their cognitive function, thus it is worthy of being applied in clinical nursing work.

Objective To observe the effect and influence on plasma angiotensin Ⅱ and oxygen radicals in the treatment of children with viral myocarditis by phosphate sodium and captopril,provide reference for clinical treat-ment.Methods 80 children with viral myocarditis met the admissions criteria were randomly divided into the obser-vation group(40 cases)and the control group (40 cases),both group were received conventional therapy,which included rest,vitamin C pin,antiviral and antimicrobial agents,nutritional medicine myocardial metabolism of drugs. The control group was given captopril 0.5mg/kg,bid,the observation group was given phosphate sodium and capto-pril,phosphate sodium 0.5 -1g/d,qd,both groups had been treated for 4 weeks for a course.Plasma angiotensin Ⅱwere detected by radioimmunoassay.The EF,FS,VA /TE were detected by echocardiography instrument.The blood were collected for detecing MDA and SOD.The clinical efficacy and electrocardiogram efficacy were evaluated. Results The clinical efficacy and electrocardiogram efficacy of observation group were 95%,90%,the control group were 70%,70%,and the difference was statistically significant(χ2 =9.367,8.571,both P <0.05).The EF,FS,SOD of the observation group and the control group after treatment was significantly higher than those of before treatment (t =11.689,8.447,9.524 and 7.714,7.985,6.166,all P <0.01).The plasma angiotensin Ⅱ,VA /TE,MDA were significantly lower than those of before treatment(t =17.572,5.772,9.744 and 9.228,3.553,3.855,all P <0.05). The SOD of the observation group after treatment was significantly higher than that of the control group(t =3.932, P <0.05),VA /TE,MDA were significantly lower than that of the control group(t =3.446,3.633,10.315,all P <0.05).Conclusion The method containing phosphate sodium and captopril can collaboratively improve heart func-tion,which may be relate to the decrease in plasma angiotensin Ⅱ and scavenging oxygen free radicals.The method can significantly improve the clinical efficacy and ECG efficacy of conventional therapies,is the better treatment for promoting in the treatment of children with viral myocarditis.

Objective To explore the relationship of peritoneal transport patterns and the nutritional status in continuous ambu-latory peritoneal dialysis(CAPD) patients .Methods 89 patients who took CAPD in 2010 January to December 2012 in the perito-neal dialysis center of our hospital were selected in this study .According to the ratio of creatinine in peritoneal dialysis solution and in blood(D/Pcr)of the peritoneal equilibrium test(PET) ,all CAPD patients were divided into HA group(high average transport) and LA group(low average transport) .Nutritional status including serum albumin(ALB) ,prealbumin(PA) ,transferrin(TF) ,hemo-globin(Hb) ,Lean body mass(LBM) ,subjective global assessment(SGA)and normalized Protein Equivalent of Nitrogen Appearance (nPNA) were compared in both groups .The relationship of D/Pcr and the nutritional status were analyzed .Results D/Pcr in HA group were significantly higher than in LA group(P<0 .01) .ALB ,PA ,TF ,Hb and SGA in HA group were significantly higher than in LA group(P<0 .01) ,but nPNA in two groups has no statistical differences (P>0 .05) .D/Pcr was negative related to ALB , TF ,Hb and SGA(P<0 .01) ,but not related to nPNA ,PA and LBM (P>0 .05) .Conclusion The nutritional status is related to peritoneal transport patterns in peritoneal HA patients ,it is necessary to strengthen nutritional guidance ,as the nutritional status is worse compared to LA ones .
