Objective To investigate the diagnosis and treatment of functional pancreatic endocrine tumors (PETs). Methods The clinical data of 45 patients with functional PETs who were admitted to the Southwest Hospital from January 1998 to December 2008 were retrospectively analyzed. Etiologic and localization diagnosis were made preoperatively according to the manifestation and the results of color doppler ultrasound and computed tomography, respectively. Eight patients received resection of the body and tail of the pancreas and spleen, 32 received tumor enucleation, one received resection of the pancreaticobiliary junction and four received pancreaticoduodenectomy. All patients received chemotherapy after the operation. Results Thirty-four cases of the PETs were benign and the rest eleven cases were malignant. Eight cases of the PETs were in the head of the pancreas,26 in the tail of the pancreas, seven in the body of the pancreas and four cases were with multiple PETs. The diameters of the PETs were 0. 3-5.0 cm, and the diameters of the PETs in 19 cases were above 2.0 cm. Eight patients were complicated with pancreatic leakage, two with incision infection and one with abdominal infection. Of the 33 patients with insulinoma, the blood glucose of five patients with multiple PETs was still abnormal after the operation, three patients underwent reoperation and the other two were treated by diazoxide to control the blood glucose in the normal range. The clinical symptoms of the seven patients with gastrinoma disappeared after the operation, and the gastric ulcer was healed, the 12-hour gastric juice volume and the level of the gastric acid were in the normal range after a continuous treatment with proton pump inhibition agents for 6 months. Necrotizing or migratory rash and diabetes of the four patients with glucagonoma were cured three weeks later, and the level of the amino acid was back to normal. Diarrhea and electronic disturbance of one patient with vasoactive intestinal peptide tumor were alleviated after the operation. Thirty-nine patients were followed up for 20-120 months. Of the 32 patients with benign PETs, two patients had tumor recurrence, and three patients died of other diseases. Of the seven patients with malignant PETs, two patients survived, and three patients died of hepatic metastasis or tumor recurrence, two patients died of other diseases. Conclusions Surgical treatment is effective for the treatment of functional PETs. Palliative resection of the tumor also can obviously improve the life quality of patients with fuctional PETs.

Objective: To explore the mechanism of acupuncture in regulating cognitive deficits in insomnia rats by observing the effect of acupuncture on microglia in thalamic reticular nucleus (TRN). Methods: Thirty rats were randomly divided into a control group, a model group and an acupuncture group, with 10 rats in each group. The insomnia model was established by intraperitoneal injection of para-chlorophenylalanine (PCPA) once a day for 2 d. Rats in the control group were intraperitoneally injected with the same amount of normal saline. Rats in the acupuncture group received acupuncture at Neiguan (PC 6) and Zusanli (ST 36) for 5 consecutive days. The CLOCKLAB 2 data acquisition system was used to dynamically observe the sleep of the rats throughout the experiment. The cognition of rats was evaluated by event-related potentials (ERPs). After intervention, brain tissue was extracted. Immunofluorescence was used to test the fluorescence expression in TRN region. The concentrations of interleukin (IL)-1β and tumor necrosis factor (TNF)-α were detected by enzyme-linked immunosorbent assay. Results: After intraperitoneal injection of PCPA suspension, the spontaneous activity in light period of rats in the model group and acupuncture group increased significantly compared with the control group (both P<0.01). After acupuncture treatment, the rats in the acupuncture group had much less spontaneous activity during the light period than those in the model group (P<0.01), and the results indicated that acupuncture could effectively improve the sleep quality of insomnia rats. Compared with the control group, rats in the model group showed that the P3 latency, the average optical density of microglia, and the concentrations of IL-1β and TNF-α increased significantly (all P<0.05), and the P3 amplitude decreased significantly (P<0.01). Compared with the model group, rats in the acupuncture group presented that the P3 latency, the average optical density of microglia, and the concentrations of IL-1β and TNF-α were significantly decreased (all P<0.05), and the amplitude of P3 was significantly increased (P<0.05). Conclusion: Acupuncture possesses an ability to improve the cognitive state in insomnia rats. The mechanism may be related to inhibiting the microglial activation, diminishing the levels of pro-inflammatory mediators like IL-1β and TNF-α, and promoting the recovery of central nervous system function.

Objective To learn the current status of health literacy of residents in Wenling City, and to explore the relationship between health literacy and socioeconomic status. Methods A total of 3200 residents aged 15-69 years old from 6 townships were selected by stratified multi-stage random sampling method and probability proportionate to size sampling (PPS) method, and a questionnaire surveyed was conducted. Results Totally 3189 questionnaires were effective and the overall level of health literacy of residents was 19.79％ (631/3189) . The percentages of residents who had the basic health knowledge and concept, healthy lifestyle and behavior, health related skills were 23.27％、 24.21％ and 23.83％, respectively. About 55.47％ of residents had the literacy of safety and first-aid, which was the highest, followed by 38.66％ with scientific health belief, 32.77％ with literacy for disease prevention, 26.12％ with health information, 14.14％ with primary medical care and 7.49％ with the literacy for chronic disease prevention. Logistic regression model showed that the health literacy level with institutions class was 2.25 times of manual workers class, and the health literacy level of people have bachelor degree or above was 6.93 times less literate or illiterate, and the health literacy level of family income of 200 thousand Yuan and above was 7.70 times of 0～50 thousand Yuan. The health literacy were different among different socioeconomic status residents (P<0.01) . Conclusion There are obvious gaps in health literacy among different socioeconomic status groups. Health education should be strengthened among residents, especially among the manual workers class, low education class and low income class.

Estrogen receptors (ERs) are members of nuclear receptors and related to several diseases such as cancer, inflammation and osteoporosis. ERs have two forms, ERα and ERβ, which have different functions and organism distributions. Compounds selectively targeting ERβ can regulate important physiological functions and avoid the side effects caused by targeting ERα. Therefore, selective ERβ ligands have received considerable research interest in recent years. In this article, different kinds of selective ERβ ligands were summarized and their structure-activity relationships were also analyzed.

Objective To establish a flow cytometric measurement of detecting minimal residual disease(MRD) according to the leukemia-associated immunophenotypes in children with acute lymphoblastic leukemia(ALL) and to explore the significance of MRD detection in ALL children for a individualized treatment. Methods A variety of four-color fluorescent antibody combinations were used to investigate the children's normal bone marrow. The normal bone marrow pattern at two-parameter plots was established to identify the residual tumor cells, seventy-five bone marrow samples from newly diagnosed ALL children were analyzed with four-color cytometry to determined the optimal combinations which can clearly distinguish the tumor cells from normal cells. The bone marrow samples were monitored with the combination panel in 60 patients at the end of induction therapy and follow-up treatment. Cytomorphology test, PCR amplification of 29 fusion genes as well as IgG and TCR gene rearrangements were performed simultaneously. Results Sixty-nine cases (92.0%) could be identified for effective antibody combinations to monitor MRD by four-color cytometry. Fusion genes or IgG and T cell receptor (TCR) gene rearrangements can be detected in 21 cases (28.0%) to monitor MRD by PCR. No MRD can be detected in 25 bone marrow samples at the end of induction therapy and follow-up treatment. Four-color cytometry could detect as low as 0.021%-4.130% residual leukemia cells. Conclusion MRD can be monitored by flow cytometry which is faster than PCR, and the sensitivity is superior to morphology method.
