OBJECTIVE: To investigate the changes of neuropeptides content in a rat model of spleen-deficiency syndrome. METHODS: Rats were randomly divided into three groups: normal group, untreated group and treatment group. There were ten rats in each group. Spleen-deficiency syndrome was induced by intragastrically administration of rhubarb concentrate in rats of the untreated and treatment group. The rats in the treatment group were intragastrically administered with Sijunzi decoction, a traditional Chinese compound herbal medicine for strengthening spleen and supporting qi. Normal saline was intragastrically administered to the rats in the normal and untreated groups. The somatostatin (SS) and cholecystokinin-8 (CCK-8) content in hypothalamus and colons was detected by the method of radioimmunoassay and the D-xylose content in urine was also detected. RESULTS: The CCK-8 content in hypothalamus of the untreated group was higher than that of the normal group (P<0.05). SS and CCK-8 content in colons of the untreated group was higher than that of the normal group (P<0.05). The CCK-8 content in colons of the untreated group was lower than that of the treatment group (P<0.05). The excretion rate of D-xylose in the untreated group was lower than that of the normal group (P<0.05). CONCLUSION: The disorder of neuroendocrine regulation in rats with spleen-deficiency syndrome may be chiefly responsible for "spleen-deficency and dysfunction of spleen" in traditional Chinese medicine.

Abstract: Objective　To understand the density changes and seasonal fluctuation of larvae and adults of Aedes albopictus in Hainan Province from 2017 to 2021, and to provide a scientific basis for the prevention and control of dengue fever and other vector-borne diseases in Hainan Province. Methods　The Breteau index method was used to monitor the larvae of Aedes mosquitoes, and the breeding sites of all small indoor and outdoor water containers and their larvae was checked and recorded. The adult mosquitoes were monitored by double lamination and light trap. Results　A total of 1 962 adult female Aedes albopictus mosquitoes were captured in Hainan Province from 2017 to 2021, accounting for 2.17% of the total captured mosquitoes. There were significant differences in mosquito species composition in different habitats in different years (χ2=312.258, P<0.01). In 2017, the density of mosquitoes in livestock sheds was the highest (9.71 per lamp·night), but the composition ratio of Aedes albopictus was the lowest (1.29%). In 2020, the mosquito density in hospitals was the lowest (2.22 mosquitoes per lamp·night), and in 2019, the proportion of Aedes albopictus in residential areas and hospitals was the highest (3.27% on average).The mosquito density in different habitats was the lowest in 2020. The proportion of Aedes albopictus in residential areas and livestock sheds showed an increasing trend from 2017 to 2021, while the proportion of other habitats showed significant fluctuations. The proportion of Aedes albopictus in hospitals showed an obvious decreasing trend in 2020. From 2017 to 2021, the average mosquito density was 5.97, 4.26, 3.82, 3.39 and 3.68 mosquitoes per lamp·night, respectively, showing a decreasing trend year by year except 2021. Except for 2019, the lure index also showed a decreasing trend, with an average value of 1.5/(hour·net), showing a decreasing trend year by year. From 2017 to 2021, the annual average density of Aedes albopictus in Hainan Province was 0.09 mosquitoes per lamp·night, showing obvious seasonal fluctuation. The Breteau index showed a slow decline from 2017 to 2021, and its annual peak was between June and August, which was 1-2 months later than the peak of adult mosquito density. Conclusions　The population density of Aedes albopictus in Hainan shows obvious seasonal characteristics. Mosquito control activities should be carried out according to the seasonal characteristics of mosquitoes to reduce the risk of dengue fever and other infectious diseases.

Objective: To examine and analyze the nm23, p16 gene expression in gastric cancer tissure,and follow up patients 5 years to discuss the relationship between nm23 and p16 gene synergy expression and gastric cancer biological characteristic and prognosis.Methods: nm23 and p16 protein in gastric cancer tissue and control were detected by immunohistochemistry,and the patients had been followed up for 5 years. Results: In 84 samples of gastric cancer, nm23 positive rate was 46.43%, p16 was 44.05%, the positive rate of gastric cancer tissue and metastasitic lymph node was lower than that of normal control, normal tissue near cancer or benign polyp,and these two genes were related to the depth of tumor invasion and clinical stage.The mortality and recurrence-metastasis rate was higher in these low expression group, and had a shorter median survive period. Conclusion: Abnormal expression of nm23 and p16 gene plays a important role in gastric cancer recurrence and devolepment and may be one of markers for evaluating tumor biological behavior and prognosis.

OBJECTIVETo observe the outcome after sacral canal injection in patients with disc herniation associated with without sciatica.

METHODSFrom December 2010 to June 2011, 65 patients with acute low back pain without sciatica due to lumbar disc herniation or bulging confirmed by CT or MRI were randomly divided into sacral canal injection group (experimental group) and lumbar oblique wrench group (control group): the experimental group had 35 cases, including 30 males and 5 females, with an average age of (43.90 +/- 1.14) years old ranging from 33 to 56 years old. The control group had 30 cases, including 27 males and 3 females,with an average age of (44.00 +/- 1.19) years old ranging from 34 to 57 years old. The course of morbidity was 1 to 3 days. All patients received sacral canal injection or lumbar oblique wrench method. The visual analog scale (VAS) scores before and at 30 min after treatment were compared between two groups.

RESULTSThe symptom of acute low back pain were relieved obviously. The average VAS scores before and after treatment in experimental group were decreased from 6.63 +/- 0.97 to 3.06 +/- 1.51,in control group were from 6.67 +/- 0.96 to 3.93 +/- 1.20 respectively. These two methods could improve the VAS score,but the effect of sacral canal injection group was better than that of lumbar oblique wrench group, there was statistically differences (P < 0.05).

CONCLUSIONIt is effective that the methods of sacral canal injection and lumbar oblique wrench applied to patients with acute low back pain without sciatica due to lumbar disc herniation or bulging confirmed, the former has better effect.

OBJECTIVETo evaluate the effect of a novel blockade technique for gastric cancer on blood-borne metastasis of gastric cancer cells to portal vein.

METHODSTwenty-three cases of gastric cancer were divided into routine operation group (8 cases intraoperatively without blockade technique) and blockade group (15 cases with blockade technique). Blood samples from portal vein pre- and intraoperatively, as well as gastroepiploic vein limited within the blockade area were obtained to detect CK19 mRNA expression by using RT-PCR technique.

RESULTSBefore the dissection of gastric lesion, the overall positive rate of CK19 mRNA expression in portal vein blood is 34.7% (9/23), including 37.5% (3/8) in routine operation group and 33.3% (5/15) in blockade group. While the course of tumor resection, those positive rates were 87.5% (7/8) in routine operation group and 6.7% (1/15) in blockade group respectively (P < 0.05). CK19 mRNA expression in the right gastroepiploic venous blood limited within the blocking area was all positive in 15 cases of blockade group.

CONCLUSIONThis blockade technique can be used effectively to block the intraoperative spread of gastric cancer cells, thus prevent blood-borne metastasis due to operative manipulation.
