Objective To provide a simple, convenient, and safe anesthesia method for the establishment of a M1 segment of middle cerebral artery occlusion model in rhesus monkey or other large laboratory animals.Method Twenty male rhesus monkeys weighing 7-11 kg (ages 7-9 years) from Academy of Military Medical Sciences were used in this study.Sumianxin injection combined with 0.1 mg/kg ketamine was given before endotracheal intubation (ID:4.5-5.5#).The animals were then transported to an interventional operation room, where the intravenous access was established and a urinary catheter was inserted into the urinary bladder.Mechanical ventilation was used during the surgery, propofol was continuously injected in a speed of 2-4 mg/kg/h, and Sumianxin-ketamine could be given if necessary to maintain adequate anesthesia depth.The dose was adjusted according to vital signs of the rhesus such as body movements, physiological parameters, and demand of surgery.Brain MRI examination was performed before and after thrombolysis.Anesthetic injection was suspended and the animals were allowed to have a spontaneous breathing every time before the MRI text.Heart rates, temperature, non-invasive blood pressure, and SpO2 were monitored during the whole surgery.Blood samples were taken from the radial artery for blood gas analysis after anesthesia induction and during operation.Results All the 20 animals underwent the operation successfully, no animal had restlessness, respiratory depression, arrhythmia and other serious complications.At the end of the study, animals awake soon.Fifteen of them survived longer than 24 hours, only 5 died from serious cerebral hemorrhage and larger cerebral infarction.Conclusions General endotracheal anesthesia is safe for rhesus monkeys during such interventional operation and MRI examination.

Objective To evaluate the effects of arterial pressure continuous output (APCO) derived from stroke volume variation (SVV)-guided fluid management in the patients undergoing supratentorial neoplasms surgery.Methods Sixty-three patients (29 males, 34 females, aged 18-65 years, ASA physical status Ⅰ or Ⅱ) undergoing elective supratentorial neoplasma surgery were randomly divided into control group (group C, CVP-guided fluid management, n=30) and GDT group (group S, SVV-guided fluid management, n=33).Before the induction of general anesthesia, the hydmxyethyl starch Voluven (130/0.4) bolus 3 ml/kg in the two groups was administered followed by infusion of crystalloid at the rate of physical requirement.Hydroxyethyl starch or vasoactive agents were administrated to achieve the goal of CVP≥8 mm Hg or MAP>80% of baseline in group C andto reach the value of SVV≤12% and MAP>70% of baselinein group S.Intraoperativecrystal, intraoperative colloids,total fluid volume, bleeding volume, volume of blood transfusion and urine volume were recorded.The radial artery and venous blood was sampled for blood gas analysis, measurement of lactate concentration and laboratory parameters at 30 min before anesthesia induction (T0), the dura mater cutted (T1), end of operation (T2) and postoperative 24 h (T3).Postoperative complications and the number of patients with complications in postoperative period, the length of ICU stay and postoperative days were assessed.Results Total infused fluid volume [(1 478±312) ml vs (1 183±294) ml] and intraoperative colloids [(775±236) ml vs (487±243) ml] were significantly higher in group S than those in group C (P<0.05).Compared with T0, the lactate concentration were decreased significantly in two groups at T1 and T2.The lactate concentration in group S was significantly lower than group C at T2 [(0.91±0.25) mmol/L vs (1.31±0.46) mmol/L](P<0.05).There was no significant difference of postoperative complications, the length of ICU stay and postoperative days between two groups.Conclusion Fluid management guided by SVV during supratentorial neoplasms surgery reduces lactate levels.

Under National Health Insurance system ( NHI) , Taiwan implemented “Family Physician Integrat-ed Health care Plan” by focusing on the key functions of primary medical institutions and family physicians. This plan had continuously strengthened the family physician system and the quality of integrated health care provision. Taiwan’s achievements and experiences were valuable for Mainland China. This paper first introduced the health sys-tem and health care provision system of primary medical institutions in Taiwan from the aspects of financing, pay-ment, health care delivery system structure, and market-capture institutions. Then, we made a comprehensive intro-duction on the policy objectives, organization structures, operation system, service schemes and health insurance pay-ment system of this plan. Finally we proposed the suggestion for integrated health care provision system in Mainland China. It is of vital importance that government should design the integrated service provision system by focusing on the key functions of family physicians. It is also of equal significance that the health administrative departments should cooperate with health insurance administrative departments to gain sufficient policy and funding resources for the plan’s successful implementation.

Cholangiocarcinoma is a malignant tumor originating from bile duct epithelial cells, among which hilar cholangiocarcinoma is the most common, accounting for about 58％-70％ of cholangiocarcinoma. Due to its atypical clinical features, special anatomical site, low radical resection rate, high recurrence rate and poor prognosis, the 5-year survival rate of hilar cholangiocarcinoma was only 14.7％-33.8％. Hence, the most effective method of hilar cholangiocarcinoma lies in early diagnosis and radical resection. Good perioperative management can improve the rate of radical resection of hilar cholangiocarcinoma and contribute a lot to prognosis of the patients. The perioperative management of hilar cholangiocarcinoma is described as follows.

Intervertebral disc degeneration is one of the common causes of chronic low back pain. As a common spinal disease， its clinical symptoms are mainly low back pain and limited function， which seriously affects physical and psychological health. Because of its complex and unclear pathogenesis， the treatment of intervertebral disc degeneration has been the focus of scientific researchers and clinical workers. At present， the treatment of intervertebral disc degeneration mainly includes non-surgical therapy and surgical therapy， which can alleviate the clinical symptoms of patients to a certain extent， but easily induce new complications， and it is difficult to restore the normal physiological function of the intervertebral disc. In recent years， along with the advanced research on matrix metalloproteinases （MMPs） in the tissues of intervertebral disc degeneration， it has been found that MMPs can be used as molecular therapeutic targets. The expression of MMPs in the intervertebral disc tissues can be regulated by reducing the content and composition of the extracellular matrix of the intervertebral disc， so as to slow down intervertebral disc degeneration and even reverse the occurrence of intervertebral disc degeneration. This treatment is expected to delay intervertebral disc degeneration caused by changes in extracellular matrix composition or content. In recent years， with the continuous development of network pharmacology and bioinformatics research， a large number of researchers have explored the treatment of intervertebral disc degeneration by traditional Chinese medicine （TCM） and found that TCM can reduce the degradation of extracellular matrix by inhibiting the expression of MMPs， thus alleviating the symptoms of intervertebral disc degeneration and slowing down the progression of intervertebral disc degeneration. This paper reviewed the research progress of TCM intervention in MMP expression in the treatment of intervertebral disc degeneration， aiming at providing references for the application of TCM in the prevention and treatment of intervertebral disc degeneration.
