The rehabilitation of a 19-year-old male with a congenital ventricular septal defect who suffered a haemorrhagic stroke from a ruptured mycotic aneurysm, secondary to infective endocarditis is described in this case study. This case study illustrates the application of the International Classification of Functioning, Disability and Health (ICF) model, and Kawa model in the structuring of a holistic, interdisciplinary team management. Application of both models provide clear communication within the interdisciplinary team and aids the team to understand the contextual factors in the interaction of the patient's rehabilitation journey.

A case study highlighting the complexity in the management of newly diagnosed atrial fibrillation in an elderly female with recurrent falls and a lack of mental capacity. This demonstrates a delicate balance between reducing thromboembolic phenomenon and bleeding risks.

This is a case study of a 58-year-old lady with metastatic nasopharyngeal carcinoma (NPC) who suffered a left neck of femur fracture. Unfortunately, there was an unexpected and rapid cancer progression, requiring her goals of care to transit from rehabilitation after her fracture to palliation. The case brings to light the need for family physicians to be poised to manage cancer patients at the end of life in the community, and work together with other stakeholders to deliver compassionate and supportive care.

Objective To determine the effects of urapidil on L-type calcium current(I_(Ca-L))in rat cardiomyocytes.Methods Ventricular myocytes were isolated from SD rats of either sex(250-280g)by retrograde perfusion of the hearts via aorta with calcium-free Tyrode solution containing enzyme as described elsewhere.Rod shaped cells with clear borders and striations were selected.Eighteen cells were randomly divided into 3 groups(n =6 each):A urapidil group;B urapidil+methysergide group and C methysergide group.All the cells in the three groups were peffused first with Tyrode solution for 1 min(T_1).In group A and C cells were then peffused with Tyrode solution containing 0.4 ?mol?L~(-1) urapidil(A)or 40 nmol?L~(-1) methysergide(C)for 1 min(T_2) while in group B cells were perfused fwst with Tyrode solution containing 0.4 ?mol?L~(-1) urapidil for 1 min (T_2) then with Tyrode solution containing methysergide 40 nmol?L~(-1) for 1 min (T_3).Finally the cells were again perfused with regular Tyrode solution for 1 min(T_4)to wash out the drugs.The peak of I_(Ca-L) was recorded at T_(1-4) by means of the whole cell patch clamp technique with use of Axo patch 200B.Results In group A,B and C the peak of I_(ca-L) at T_2 was significantly lower than that at T_1 but there was no significant difference between the peak of I_(ca-L) at T_1 and T_4.In group B the peak of I_(Ca-L) at T_3 was significantly lower than that at T_2.Conclusion Urapidil inhibits L-type calcium current in rat isolated cardiomyoeytes.It's inhibitory effect may not be mediated by 5-H_(1A) receptor.

ObjectiveTo investigate the efficacy of combined therapy of mild hypothermia and hibernation to treat severe brain injury. Methods24 patients with severe brain injury were randomly divided into combined therapy group and normothermia group. Glasgow Coma Scale scores of all the patients were in the range of 3 to 8. No later than 10 hours after their injury, hypothermia patients were given half dosage of No.1 hibernation cocktail and had been cooled by cooling blankets to 32℃-34℃ (rectal temperature) for 5 days, then to 35℃ for 24 hours, and slowly increased to their normal level. 3 days and 7 days after their admission, intracranial pressure,creatine phosphate kinase,partial pressure of arterial O2 and CO2, platelet and Na+,K+ were measured.7 days after their admission, Glasgow Outcome Scale scores of each patient and mortality of each group were measured. ResultsThe mortality of combined therapy group(25.0%) was significantly lower than that of normothermia group (66.6%,P<0.05). The decreased values of intracranial pressure, creatine phosphate kinase and platelet number of combined therapy group were all significantly higher than that of normothermia group respectively (P<0.05). There were no significant difference in mean artery pressure, blood electrolyte, and partial pressure of arterial O2 and CO2 between these two groups(P>0.05). ConclusionThe combined therapy of mild hypothermia and hibernation can effectively reduce the mortality of patients with severe brain injury as it is much easier, less invasive and with less complications.

OBJECTIVETo develop a new method for the determination of cholesteryl palmitate in Oviductus Ranae.

METHODA HPLC method was set up, using Zorbax Silica column and cyclohexane-diethyl ether (40:1) as mobile phase with a flow rate of 1.0 mL x min(-1), and the UV detection wavelength was 203 nm.

RESULTThe calibration curve was linear over the range of 0.60-8.92 microg (r = 0.9997), the average recovery of the method was 98.4%. RSD 1.8% (n = 6).

CONCLUSIONThe results showed that method was reliable and accurate.
