Objective To evaluate the effect of malaria control in Shayang County from 1995 to 2014,so as to provide the evidence for the strategy revision of the elimination of malaria prevention and control. Methods The data of malaria surveil?lance were collected and analyzed in Shayang County from 1995 to 2014. Results During the 20 years,582 malaria patients(9 imported patients)were reported. The average annual incidence rate was 0.53/ten thousand. Through the comprehensive preven?tion and control measures,the incidence of malaria decreased from 2.30/ten thousand in 1997 to 0.02/ten thousand in 2010,and the decreasing rate was 99.13% . The proportion of malaria cases in the total infectious diseases cases also decreased from 21.23% in 1997 to 0.07% in 2010,and the decreasing rate was 99.67%. There were no local malaria patients from 2010 to 2014. However,the imported malaria patients were increased year by year during the recent years. Conclusions This county has reached the national malaria control and elimination standards,and the malaria control work has been transferred from the con?trol period to the elimination phase. We should implement the prevention and control measures and strictly control imported ma?laria,so as to consolidate the malaria control results.

Specimens of 50 adult brain with meninges were examined under magnificationof 5?.The number of the superior cerebral veins(SCV)varies considerably on bothsides.Cases with 7 branches on one side are most commonly seen. SCV perforate the arachnoid either at the superior border of the cerebral hemi-sphere or far beyond it.More branches perforate the arachnoid beyond the superiorborder of the cerebral hemisphere.The length of SCV between the superior borderof the cerebral hemisphere and the point where the veins perforate the arachnoid ismeasured and in average,the length of the frontal veins and veins of central gyriis longer than that of the parieto-occipital veins.The outer caliber of the frontopolar veins and occipital veins is the smallest andthat of the combined trunk veins is the largest.Bridge veins usually occur in the branches of SCV except the left central vein.The incidence of the bridge vein in the left and right frontopolar veins is thehighest(50～60%).There is an adherent segment occurring in all branches of SCV.The incidenceof the adherent segment in different branches is almost over 50%.Therefore it maybe considered that the presence of the adherent segment in SCV is a normal pheno-menon.The frontal veins and the veins of the central gyri usually adhere to thedura,and the parieto-occipital veins to the lateral wall of the superior sagittal sinusand the cerebral falx.Very few perforated segments can be seen in frontal veins,yet the percentageof its presence in the both sides of the veins of central gyri and parieto-occipitalveins are 9% and 11.22% respectively.Any vein with a perforated segment per-forates the lateral wall of the superior sagittal sinus predominantly.The application of the bridging vein,or adherent segment and perforated seg-ment of the SCV in neurosurgery has been discussed.

The morphology of the extraglandular and intraglandular portions of the adrenal veins and other veins concerned with the catheterization in adrenal venography was observed on 53 adult cadavers.The extraglandnlar portion of both adrenal veins is of single trunk type on all the specimens. The left adrenal vein consistently ends into the left renal vein while the right adrenal vein ends into the inferior vena cava in 83.02% of cases and into the right accessory hepatic vein in 9.43%.The length and diameter of the extraglandular portion of the left adrenal vein are 23.05?5.96 mm and 4.99?0.82 mm and those of the right adrenal vein are 8.73?5.13 mm and 2.93 ? 0.87 mm. The angle formed by the left adrenal and left renal veins is 117.35?11.95? and that formed by right adrenal vein and inferior vena cava is 47.5?14.58?.The distances from the femoral vein(lower margin of inguinal ligment)through the external and common iliac veins and inferior vena cava to the hila of both adrenal glands were measured. They may be used as references in performing adrenal venography.The intraglandular portion of the adrenal veins is of three types: single, double and triple trunk types. The single trunk type is the most common occurring in 86% of the left adrenal veins and 50% of the right veins. The triple trunk type exists only on the right side.In addition, the feasibilities and difficulties of the catheterization of the both adrenal veins were discussed according to the anatomy studied.

The superficial middle cerebral veins (SMCV) of 50 human heads were dissectedunder the operating microscope (10?).There were 122 terminal braches of the SMCV in the specimens and the typesof their drainage can be divided into four:type 1 (41.00%)—drains into the caver-nous sinus;type 2 (24.60%)—drains into the variant venous sinus in the lateralwall of the cavernous sinus;type 3(28.70%)—drains into the variant venous sinus inthe dura of the middle cranial fossa;type 4(5.70%)—drains into other dural venoussinuses.Type 1 may be considered as normal and the others as variant.The two variant dural venous sinuses reported are respectively located in thelateral wall of the cavernous sinus,named“the lateral wall sinus of the cavernoussinus”,and in the dura of the middle cranial fossa,named the“variant sinus ofthe middle cranial fossa”.The former occurred 27% in the specimens and the later25%.We have discussed about the drainage of the SMCV and two variant dural ven-ous sinuses on the embryonic basis and the clinical practice.

Background: Numerous studies suggest that intravenous propofol is superior to inhaled volatile anesthetic. This study compared the changes in the endoplasmic reticulum (ER) stress of cancer cells and lymphocytes after propofol- and sevoflurane-based anesthesia during breast cancer surgery. Methods: We randomized 53 patients undergoing breast cancer surgery to propofol (n = 28) and sevoflurane (n = 25) anesthesia groups. Blood samples were obtained immediately before inducing anesthesia, and 1 and 24 h postoperatively. Human breast cancer cell lines were cultured and treated with patient plasma, and the frequency of C/EBP homologous protein (CHOP) on the cancer cell lines and lymphocytes was measured. The neutrophil-to-lymphocyte ratio in plasma was evaluated in both groups. Results: The CHOP expression on breast cancer cell lines did not differ between the groups (P = 0.108), although it decreased significantly over time (P = 0.027). The CHOP expression on lymphocytes was comparable between the groups (P = 0.485), and was the neutrophil-to-lymphocyte ratio (P = 0.501). Conclusions Propofol-based anesthesia did not induce greater ER stress than sevoflurane-based anesthesia during breast cancer surgery. The ER stress of cancer cells did not differ according to the type of anesthesia during breast cancer surgery.
