Objective To investigate the pathogenesis of hyperthyroidism combined with cerebral infarction and the relationship between hyperthyroidism and cerebral infarction. Methods Data from the clinical manifestations, diagnosis, and therapeutic outcomes of 10 patients with hyperthyroidism combined with cerebral infarction were analyzed retrospectively. Results After treatment with drugs for anti hyperthyroidism and active treatment of cerebral infarction, no severe complications were found in all patients. Conclusion Hyperthyroidism combined with cerebral infarction may be one of the important causes of adolescent cerebral infarction. Treatment of hyperthyroidism may play an important role in the treatment of cerebral infarction.

The incidence of malignancy tumors has increased significantly recent years in patients with type 2 diabetes mellitus (T2DM).As the first-line oral medicine of T2DM,in addition to the safe and effective hypoglycemic effect,metformin can reduce the incidence and mortality of cancer,and improve the prognosis in T2DM patients.While the exactly anti-tumor mechanisms of mefformin is not yet clear,which might be the inhibition of proliferation and promotion of apoptosis of tumor cells mainly by acting on an adenosine monophosphate activated protein kinase (AMPK) and microRNAs (miRNAs).And metformin can inhibit migration and invasion of tumor cells,as well as strengthen the effects of chemotherapy drugs.This article reviews the recent research progress of clinical and epidemiological studies and anticancer mechanisms of metformin.

OBJECTIVE:To review the status quo and problems in the study of TCM formula granule.METHODS:Recent literature concerning the preparation technology and the normalization of quality criteria,etc.of TCM formula granule reported were reviewed and analyzed.RESULTS&CONCLUSION:TCM formula granule was of many merits such as safe and sani-tary,accurate in dosage measurement,portable etc.However,there are also some problems yet to be solved.

OBJECTIVE: To avoid the infection induced by the clinical application of total parenteral nutrition solution( TPN) . METHODS: The experience of quality control and etiological examination in the preparation and application of TPN for 62 patients in our hospital were analyzed retrospectively. RESULTS & CONCLUSION: The key to reduce the incidence of infection in the preparation and application of TPN is to keep the infection source under control.

Purpose To discuss the main index of the colour ultrasonographic diagnosis of children's left Renal Vein Entrapment Sydrome(LRVES).Methods By colour ultrasonography,urine microscope examination and urine Ca/Cr ratio determination,eighty-two LRVES children were diagnosed and compared with forty healthy children.Observed at supine position whether narrow caused by pressure or the expanding phenomenon of LRV after being pressed,to examine the ratio of the abdominal aorta(AO) left internal diameter(a) to the front internal diameter(b) of LRV,by using CDFI,blood flow rate in the left lateral position of LRV was judged.Simultaneously,the angle(?) between superio mesentery artery(SMA) and AO was detected.Then standing upright for twenty minutes,and determined a/b ratio.Results In the LRVES group,the LRV blood vessels become narrower,a/b was over 3 at supine position,after standing upright for twenty minutes,a/b was over 4;and LRV blood flow rate becomes slower,? angle becomes smaller,compared with the healthy group,there was statistical significance.Conclusions The main indexes of the LRVES of ultrasonographic diagnosis is to observe the a/b ratio of LRV before and after being pressed (lying on the back and standing upright for twenty minutes) and to detecte the blood flow rate of LRV before pressure and judege the angle between SMA and AO.

Objective: Large-conductance calcium-activated potassium (BKCa) channel modulates vascular smooth muscle tone. In the present study, we tested the hypothesis that salt, one of the factors which significantly influence blood pressure (BP), can regulate BKCa activity and then elevate blood pressure. Methods: Male Sprague-Dawley rats aged 6 weeks were randomized into high salt diet group (HS) and control group, fed with high salt diet (containing 5% NaCl) and standard rat chow (containing 0.4% NaCl) respectively for 16 weeks. Tail systolic blood pressure (SBP), body weight (BW) and 24-hour urinary output were tested every 4 weeks. Content of urinary Na+ was detected using flame spectrophotometrical method. At the end of 16 weeks, all the rats were killed, the mesenteric arteries were obtained, and single mesenteric smooth muscle cells were isolated at once. The resting membrane potential (Em), the total potassium currents and the currents after perfusion with TEA solution of the cells were all recorded by whole cell patch clamp. The transcriptions of BKCa channel α and β1 subunits in mesenteric arterial vascular smooth muscle cells (VSMC) of each group were calculated by real-time RT-PCR. Results: There was no difference in SBP and BW at each stage between control group and HS group; the urinary Na+ level in HS animals was elevated significantly after 4 weeks. The negative values of Em in HS group VSMCs were reduced compared with those in the control group. Transcriptions of β1 subunit of BKCa channels were decreased in HS group, but α subunit transcriptions did not differ between the two groups. Whole cell potassium currents did not differ between HS and control groups, but BK Ca currents of HS group VSMCs were lower than those of control group ones. Conclusion: Even without elevating SBP, salt-loading can still modulate the expression and activity of BKCa channel in the mesenteric arterial VSMC and elevate vascular tone.
