The association of spontaneous intracranial hypotension with cerebral venous sinus thrombosis is rare. We report here a case of extensive cerebral venous sinus thrombosis involving three sinuses following spontaneous intracranial hypotension. The patient presented no other thrombotic risk factors except for spontaneous intracranial hypotension. This case adds to the evidence that spontaneous intracranial hypotension is a risk factor for cerebral venous sinus thrombosis.

In order to clarify the regulatory mechanism of the neurohormone releasing in the neurohypophysis, the immunohistochemical and chemical lesion method were combined to demonstrate the vasopressin (VP)-and catecholamine (CA)-containing nerve terminals, and their distribution and relationship were observed under electron microscopic level. The results showed that in the rat neurohypophysis there were not only widely distributed VP nerve terminals, but also there were many 6-OHDA induced degenerated nerve endings. The close relationship even synapse-like contacts existed between the CA-ergic endings and pituicytes as well as microglial cells. It was very interesting that the CA-ergic boutons formed axoaxonic synapses with VP-containing boutons. In this case, the CA-bouton was presynaptic element whereas the VP-bouton served as postsynaptic element. The above mentioned results probably provided ultrastructural evidence for the regulatory mechanism of the neurohormone releasing in the neurohypophysis for the first time.

AIM: To explore the effects of prostaglandi n I 2 (PGI 2) on mesenteric microcirculation and hemorheology during renal isch emia/reperfusion (IR) injury. METHODS: 36 rabbits were randomly distributed into the sham oper ated group (sham group), renal ischemia/reperfusion injury group (IR group) and PGI 2+IR group(PGI 2 group). IR group received clamping for 60 min follow ed by 120 min of reperfusion. A microcircular microscope image analysis system w as used to study the changes of mesenteric microcirculation and hemorheology at 60 min of ischemia and 120 min of reperfusion, respectively, while the blood sa mples were obtained for the measurement of hemorheological indexes. RESULTS: ① In IR group during the period of renal IR, the numb er of adhesive leukocytes and microthrombus, hemorrhage and hemorheological ind exes such as blood viscosity, plasma viscosity, blood reduction viscosity, he matocrit, erythrocyte aggregation index, erythrocyte sedimentation rate, eryt hrocyte sedimentation rate K and plasma fibrinogen were significantly higher, w hile microvascular diameters, blood flow velocity and erythrocyte deformation i ndex were significantly lower compared with sham group (P0.05). CONCLUSIONS: PGI 2 ameliorates the disturbance of mesenteric microcirculation and hemorheology caused by renal IR injury with the best effect at 10 ng?kg -1?min -1.

The development of orthopedic fixing materials is a most basic and active aspect in orthopedic injury treatment.Their invention and application of early manual splints,gypsum bangs,hot-shaped splints,polymeric bangs and so on,greatly promoted orthopedic fixing performance and varied the strategies of orthopedic injury treatment.By repeated experiments and clinical trials,we developed a new orthopedic fixing material using polymeric materials.Convenient to operate,easy to remove,auto-shaped,X ray transmittable,water proof and durable,it not only satisfies the needs of fixing different parts of the body,but also remedies the defects of earlier fixing materials,and therefore has gained an extensive application as the best fixing material for the treatment of clinical and battle-field bone fractures.Further studies on it will surely better its properties,reduce its cost and lead it to a wider application.

A total of 296 patients were randomly divided into short message group (n =153) and non short message group (n =143).The former group received short message service (SMS) for follow-ups while the latter group had routine oral follow-ups.The return visit rate,recall rate of glycosylated hemoglobin (HbA1c),HbAlc level and glucose control rate for diabetics were assessed after one-year follow-up.The return visit rate (96％) and recall rate of HbAlc (78％) in the short message group were significantly higher than those in the non-short message group (59％,25％,P ＜0.01 for both).The HbAlc level after one-year follow-up (6.51 ± 0.74) ％ was lower than that one year before (6.85 ± 1.26) ％ in the short message group.The glucose control rate after one year (82％) were significantly higher than that one year before in the short message group (65％) and that after one year in the non-short message group(59％,P ＜ 0.01).Use of SMS platform system for follow-ups and health education can effectively improve the return visit rate and glucose control rate,lower the HbA1c level.in diabetics.

OBJECTIVE:To optimize the inclusion technology of Eugenol-β-cyclodextrin (β-CD) inclusion complex,and to identify and characterize it. METHODS:With the molar ratio of eugenol to β-CD,inclusion temperature and inclusion time as fac-tors,using the yield of inclusion compounds as index,the inclusion technology was optimized by orthogonal test. The formation of inclusion compound was identified by the spectra change of FT-IR,XRD and 1H NMR. Its structure was characterized by 1H RO-ESY NMR. RESULTS:The optimized inclusion conditions were that the molar ratio of eugenol to β-CD was 1.0:1;inclusion tem-perature was 60 ℃;inclusion time was 2.0 h. And the yield of inclusion compound was 73.86%(RSD=0.17%,n=3). 1H NMR results ofβ-CD and its inclusion complex indicated that the optimum qualitative ratio of the inclusion complex was 1.0:1. The inter-molecular interaction between eugenol and β-CD was confirmed by the spectrum analysis of FT-IR and XRD. 1H ROESY NMR re-sults indicated the structure of inclusion complex mainly was that the phenyl of eugenol was in the cavity of β-CD,the vinyl was outside. CONCLUSIONS:The inclusion technology is reasonable and feasible,and can be used for the inclusion of eugenol andβ-CD. The formation of inclusion compound is confirmed by the spectrum analysis.

OBJECTIVE:To assess the cost and therapeutic effects of Chinese traditional medicine and western medicine in treating varicocele sterility. METHODS:165 patients with sterility were randomly divided into 2 groups. Chinese traditional medicine group included 110 cases who took Zhang's varicosity prescription, while the western medicine group included 55 cases who took human chorionic gonadotropin, clomiphene citrate, zinc gluconate, ATP and vitamin AD,Vitamin E,Vitamin C,for 3mo～9mo normally. The therapeutic effects and adverse effects of two groups were monitored and evaluated with cost- effectiveness analysis. RESULTS:The total effective rates of Chinese traditional medicine and western medicine were 81.82%and 50.91% respectively, while the costs were 3 688.2 Yuan and 2 399.2 Yuan accordingly, C/E were evaluated to be 45.08 and 47.13 respectively and ?C/?E was 41.7. CONCLUSION:Zhang's varicosity prescription is the better choice for treatment of varicocele sterility
