OBJECTIVETo explore material bases and neurobiological mechanisms of "Shen storing will" by observing learning and memory capacities and N-methyl-D-aspartic acid (NMDA) receptor expressions in Shen deficiency constitution (SDC) rats.
METHODSTotally 40 SD rats were randomly divided into the model group, the Zuogui Pill (ZP) group, the Yougui Pill (YP) group, the blank control group (consisting of normal pregnant rats), 10 in each group. SDC young rat model (inherent deficiency and postnatal malnutrition) was prepared by the classic way of "cat scaring rat". Medication started when they were scared by cat. Rats in the ZP group and the YP group were administered by gastrogavage with ZP suspension 0.1875 g/mL and YP suspension 0.0938 g/mL respectively. Equal volume of normal saline was administered to rats in the blank control group and the model group by gastrogavage. All medication was given once per day, 5 days in a week for 2 consecutive months. Learning and memory capacities were detected by Morris water maze test. Expressions of NMDA receptor subunits NR2A and NR2B in hippocamus were detected by immunohistochemical method.
RESULTSCompared with the blank control group, the latency period, total distance in Morris water maze test were longer in the model group (P < 0.05). All the aforesaid indices all decreased in the ZP group and the YP group, with statistical difference when compared with the model group (P < 0.05). The protein expressions of NR2A and NR2B in hippocamus were lower in the model group than in the blank control group (P < 0.05). But when compared with the model group, they were obviously higher in the ZP group and the YP group (P < 0.05).
CONCLUSIONSSDC rats had degenerated learning and memory capacities and lowered NMDA receptor expressions. ZP and YP could up-regulate learning and memory capacities and NMDA receptor expressions, thereby improving deterioration of brain functions in SDC rats.

To discuss the protective effect of aralosides (AS) on I/R-induced rat myocardial injury. The adult rat ventricular myocyte ischemia model was established through perfusion with sodium lactate perfusate and reperfusion with Ca(2+) -containing Tyrode's solution simulation. The cell contraction and ion concentration synchronization determination system was applied to detect the effect of AS on single I/R cell contraction and Ca2+ transients. According to the findings, AS could increase resting sarcomere length, contraction amplitude, ± dL/dt(max), calcium transient amplitude and speed of post-reperfusion myocardial cells (P < 0.05, P < 0.01), and decrease in time for achieving 90.0% of maximum relaxation, time for achieving peak value, resting calcium ratio, contraction period [Ca2+] i, time for achieving 50.0% of maximum relaxation and attenuation rate of intracellular calcium transient (P < 0.05, P < 0.01). Therefore, it is suggested that AS improved the post-reperfusion cell contraction and injury of calcium homeostasis.

OBJECTIVETo describe the distribution changes of the mortality rate for cervical cancer in China between the 1970's and 1990's and provide the scientific evidence for the prevention and control strategies for cervical cancer campaign in China between next century.
METHODSData from two National Surveys for the Causes of Death in 1970's and 1990's in China. The crude and adjusted mortality rates for the cervical cancer and the distributions based on age and area were calculated and described. The comparison of the differences of changes between two mortality rates periods and together with its trends were shown based on the age-standardized.
RESULTSDuring two decades, the mortality rate for cervical cancer was 10.7 per 100,000 in 1970's which declined to 3.89 per 100,000 in 1990's, and from the 3rd ranking among all female malignant tumors to the 6th in 1990's (decreased about 63.64%). But the declination was not evenly. There have still been some high-risk areas, most located in rural countries in the mid-west of China, with rates remain unchanged and even at the highest level in the world, such as Wudu in Gansu and Yangcheng in Shanxi. A big difference was showed between rural country and city, but in both of them, the mortality rates in 1990's were significantly much lower than in 1970's (P = 0.001) at each five-year age group. And in the city, there was a much sharper increased trend in young women in 1990's.
CONCLUSIONSThe mortality rate for cervical cancer campaign in China has been substantially declined during past twenty years, but it's still a major health problem for women, especially in rural China. The focus of the prevention and control for the cervical cancer in the next century should put on rural areas, especially in mid-west of China and young women in the city.

Objective To compare the efficacy of ultrasound-guided fine-needle aspiration(US-FNA)biopsy in diagnosing solid and complex thyroid nodules with different size. Methods One hundred and seventy-five thyroid FNA biopsies were prospectively performed on 168 patients ranging from 4 to 75 years of age. Sixty-three nodules were surgically excised and the others were clinically followed-up. The cytology diagnoses were categorized into four groups: benign, malignant, suspicious and unsatisfactory. Results There was no significant complication in the all 115 solid and 60 complex thyroid lesions and there were 36and 3 malignant nodules respectively in solid and complex thyroid nodules. The nondiagnostic rates of solid and complex nodules were 7% and 8%. The accuracy of US-FNA in diagnosing complex thyroid nodules was comparatively equal to that of in solid thyroid nodules. In solid thyroid nodules, the sensitivity and accuracy in ≤1 cm group were similar to that of in >1 cm group. Conclusions US-FNA was an accurate and reliable method to diagnose thyroid solid and complex lesions.

OBJECTIVETo study the clinical effect of segmental resection of the liver using Glissonean pedicle transection for primary liver cancer.
METHODSThe clinical data of 55 primary liver cancer patients admitted from January 2006 to October 2008 were analyzed retrospectively. Twenty-five of the patients underwent segmental resection of the liver by Glissonean pedicle transection (group A), and 30 underwent routine hepatectomy (group B). The positivity rate of the resection margin, micrometastasis in the hepatic parenchyma surrounding the lesions and postoperative recurrence rates were investigated.
RESULTSThe positivity rate of the resection margin was 4.0% in group A, significantly lower than that of group B. The number of histological micrometastasis was significantly higher in group A than in group B (16 vs 8). The median distance of histological micrometastasis was 6.8 mm (2.7-25.6 mm) in group A and 4.2 mm (2.4-9.0 mm) in group B. The one-year recurrence rate was significantly lower in group A than in group B (16% vs 26.7%).
CONCLUSIONGlissonean pedicle transection for segmental liver resection is a simpler procedure than routine hepatectomy for primary liver cancer and can reduce the number of histological micrometastasis and recurrence rate.
