The incidence of gastric carcinoma is increasing and lymphatic metastasis is one of the major causes of death.Vascular endothelial growth factor-C(VEGF-C),Vascular endothelial growth factor D(VEGF-D)linking their receptor(VEGFR-3)can increase lymphangiogenesis,advance lymphatic metastasis,and relate to lymphatic vessel density of tumor.More and more studies of lymphatic vessel of gastric carcinoma cause great attention.We summarizeed the mechanism of lymphangiogenesis,the new development of relationship between lymphangiogenesis and lymphatic vessel density and their clinical significance.

Objective To observe the therapeutic effect of the integration of Longji-Huoluo pill and mild manipulations Tuina therapy for the teenagers with lumbar intervertebral disc protrusion. Methods Eligible teenager patients with lumber intervertebral disc protrusion were randomly classified into two groups according to the single blind method and the treating sequence, 69 patients in the treatment group and 58 patients in the control group. The Longji-Huoluo pill and mild Tuina manipulations were adopted on the basis of the convertional treatment in the treatment group. While ibuprofen sustained release capsules and mecobalamin were given to the control group beside the convertional treatment. Both groups were treated for 4 weeks. The CT examinations were applied before and after the treatments to observe the absorption of the prolapsed lumber intervertebral disc. The Visual Analogue Scale (VAS) was used to test the pain degree and to estimate the clinical effect. Results The VAS scores in the treatment group (4.03 ± 1.67 vs. 5.41 ± 1.55, t=10.121) and the control group (3.61 ± 1.34 vs. 5.96 ± 1.71, t=11.086) after treatment were significantly lower than those before treatment (P<0.05). The sagittal diameters of the prominence in the treatment group (2.12 ± 1.89 mm vs. 4.62 ± 0.34 mm, t=2.281) after treatmentwas significantly lower than that before treatment (P<0.05). The total effective rate of the treatment group was 87.0%(60/69), and the control group was 72.4%(42/58). Statistical significance was detected on the difference of the two groups (U=1.913, P=0.043). Conclusions The integration of manipulations can effectively relieve the pain and can return the prominent disc. The therapeutic effect is considered equivalent to western medicine.

Objective To explore the situation and the impact of early postnatal sucking and health educa-tion on early maternal lactation physical rehabilitation of primipara.Methods 100 primiparas were randomly divided into two groups,50 cases in each group.The control group received routine care,the observation group was given suck and health care education on the basis of the control group.The maternal lactation and physical rehabilitation was compared between the two groups.Results The good rate of the maternal health knowledge in the observation group was 92.00%,the good rate of ability of nursing master was 86.00%,the lactation time was (16.46 ±2.43)h,which were significantly better than the control group(χ2 =14.03,14.89,t =10.22,all P <0.05).The postpartum rehabil-itations of the observation group were better than those of the control group(t =3.86,4.42,4.68,5.67,677,5.46, 571,4.27,3.98,508,all P <0.05).The incidence rate of complication of the observation group was 6.00%,which was significantly lower than 22.00% of the control group(χ2 =5.24,P <0.05).Conclusion First mothers receive early postnatal sucking and health education can increase their milk production capacity,promote physical rehabilitation.

Abstract: Objective To summary and analyze the epidemic situation of imported malaria and the prevention and control measures implemented during the new crown pneumonia epidemic in Shenzhen, so as to provide reference for the prevention and control of imported malaria under COVID-19 epidemic. Methods　The data on the prevention and control of malaria epidemic in Shenzhen from 2017 to 2021 were collected for analyzing the epidemic situation of malaria, measures taken and the effect of prevention and control with descriptive epidemiological methods. Results　From 2017 to 2021, a total of 104 confirmed malaria cases were reported in Shenzhen, all of which were imported from abroad. 97.1% were imported from Africa, mainly falciparum malaria, accounting for 80.8%. The age of onset was mainly young adults, the age group 20-49 years accounted for 81.7%, and most of the patients were overseas migrant workers, accounting for 59.6%. Imported malaria cases were reported in each month, the most was 13 cases in July, then 12 cases in September. From 2017 to 2021, 709 mosquito trap lamps were placed, and 3 523 mosquitoes were captured, with an average mosquito density of 2.60 per lamp and night. Anopheles were not found, and the dominant species were Culex quinquefasciatus. During the outbreak of COVID-19, Shenzhen has implemented a series of measures in terms of improving the working mechanism of multi-departmental cooperation and joint defense, strengthening screening and monitoring, personnel training, mosquito vector control, and material security, so as to achieve early detection, early transfer, early isolation and early treatment. Conclusions　A series of measures have been comprehensively implemented to prevent and control imported malaria in Shenzhen while preventing and controlling imported new coronary pneumonia, and achieved positive results. It has realized the timely identification of cases and effective treatment, and prevented the occurrence of severe and fatal malaria cases, as well as halting the spread and spread of malaria outbreaks.

In 1957. we discovered a new species of Trombicula in gaohu, Qingtian. mountainous region of south Zhejiang. which is the dominant species in that locality. Its seasonal and geographical distribution are consistent with tbe epidemic of tsutsugamushi disease. The Rickettsia tsutsugamushi had been isolated from the larva hosts and patients at the same time. It was confirmed by epidemiological investigation that this tsutsugamushi is a new vector of tsutsugamushi disease. This Trombicula was discovered first time in Gaohu and was named Trombicula (Leptotrombidium) Caohuensis nov sp. This rteport had been published in 1960.In July 1984. we tested a biting experiment by setting 11 larvae of the tsutsugamushi on our own forearms and confirmed that the Trombicula had the ability of stinging and biting human bodies, and that this ability persisted after the changing of hosts (from mouse to man). This test provided a new evidence of vector effect of Trombicula Caohuensis nov sp in ecology.
