The fossa of the lacrimal sac and the naso-lacrimal canal in 506 crania(1,012 sides)of the Chinese were measured.Among them,374 crania are adult male and 132 crania are adult female.The main results obtained are summarized as follows: 1.The fossa of the lacrimal sac: male female average (1)height 16.79mm 16.41mm 16.60mm (2)width 7.74mm 7.57mm 7.66mm (3)width of the portion of the lacri- mal bone 4.08mm 3.87mm 3.98 mm (4)width of the portion of the frontal process of maxilla 5.51mm 5.43mm 5.47mm (5)width of the part anterior to the crest of the frontal process of ma- xilla 7.22mm 6.69mm 6.96mm (6)width of the part posterior to the crest of lacrimal bone 6.93mm 6.80mm 6.87mm (7)deepness 3.44mm 3.34mm 3.39mm (8)thickness of the middle part of ant- erior lacrimal crest 5.68mm 5.22mm 5.45mm (9)distance from anterior ethmoidal foramen to the anterior border of trochlear fossa 20.54mm 20.28mm 20.41mm 2.The naso-lacrimal canal male female average (1)transverse width of the upper ori- fice 6.06mm 5.84mm 5.95mm (2)length 17.29mm 16.29mm 16.79mm (3)distance from the lower orifice to piriform aperture 7.79mm 7.92mm 7.86mm (4)length from the upper orifice to the floor of the inferior nasal me- atus 29.62mm 28.61mm 29.12mm

The pterion of 739 crania of the Chinese (adult male 486 cases, adult female 181 cases and young specimen of both sexes 72 cases) was studied. The pterion in the form of spheno-parietal suture was highest in percentage (77.94?1.08％). The percentage of the form of epipteric bone (19.22?1.02％) was higher than that of the temporofrontal suture (2.03?0.36％). The K-form represented only in 0.81?0.23％. In the form of spheno-parietal suture, the percentage of the wide H-type was highest (57.98?1.28％). The form of epipteric bone was found to be more common in nonadults than in adults. The N-type occurred more frequently in the male adults than in the female adults. Region and side failed to show any statistical importance in the percentage distribution of other forms. The group with epipteric bones was divided into three main classes, namely, with a single os epiptericum, with double, or multiple ossa epipterica. The percentage of those with a single os epiptericum was much higher (82.04?2.28％) than that of the other two classes (15.14?2.12％ and 2.82?0.92％). In the forms of the single os epiptericum, os epiptericum posterius was found in 6.77?0.66％, os epiptericum typicum in 6.50?0.64％, and os epiptericum anterius in 2.30?0.39％. In the forms of the double ossa epipterica, the united type occurred in 2.50?0.41％ and the separated type in 0.41?0.16％. In the forms of the multiple ossa epipterica only the united type was found in 0.54?0.18％. The centre of pterion was situated at 30.1 mm behind and 11.7 mm above the fronto-zygomatic suture or 37.7 mm above the baseline. In the pterion region the presence of the canal for the anterior branch of the middle meningeal artery was 60.83?2.75％. The bony canal that lay opposite the centre of pterion occurred more frequently in percentage 44.27?2.80％ and that lied below and behind the centre of pterion was relatively small in number (6.69％ and 6.37％), however, that lay in front of the centre of ptetion occurred only in 0.96％.

The intracranial portion of the vertebral arteries and the basillar artery of 103 Chinese (80 adults and 23 children) brains have been studied. The diameter of the intracranial portion of the vertebral artery on the left side is usually greater than that on the right side. The anterior spinal artery comes off mostly from the vertebral artery. It descends, slants medially and unites with the opposite artery to form a single anterior spinal artery in front of the anterior median fissure of the medulla oblongata. The vertebral artery usually gives off 1～3 medullary branches, which enter the medulla oblongata mostly through the posteriolateral sulcus. The blood supply of medulla oblongata has been discussed.In 57.50?5.53% of the adults, the union of the right and left vertebral arteries to form the basilar artery was found at the level of pons, while in children, 47.83?10.39% was found at the level of the lower border of pons. The labyrinth arteries arise mostly from the anterior inferior cerebellar arteries (77.50?2.95), and in rare cases, from the superior cerebellar or vertebral arteries. The pontine branches coming off from each side of the basilar artery are usually 3～4 in number.

The cerebellar arteries including the arterial supply to the dentate nucleus had been studied on 103 Chinese brians (80 adults, 23 children) by dissection, angiography, clearing method and dissection under stereoscopic microscope. The following results were obtained:1. The superior cerebellar artery which arose mostly from the upper end of the basilar artery near the posterior cerebral artery was one(82.52?2.68％)or two (17.48?2.68％) in number on each side. It was grouped into simple-trunk type (one trunk on each side 69.90?4.52％), double-trunks type(two trunks on each side 4. 86?2.13％), and mixed type (one trunk on one side and two on the other 25.24?4.28％).It passed backward around the cerebral peduncle and was more frequently divided into lateral and medial branches.2. Most of the anterior inferior cerebellar arteries sprang from lower third (66.49?3.29％) and middle third (12.14?2.69％) of the basilar artery. The rest (15.06?2.69％) sprang from posterior inferior cerebellar and vertebral arteries and upper segment of the basilar artery. It was absent in 6.31?1.69％.3. The posterior inferior cerebellar artery arose mostly from the vertebral artery (77.18?2.92％)and was absent in 6.80?1.95％. It formed a loop at its original segment and gave off 1～4 branches to medulla oblongata.4. The middle inferior cerebellar artery was present in 17.48?3.95％ and occurred on both sides in two cases.The course, position, distribution of all arteries mentioned above and their interrelationships were observed.5. The arteries to the dentate nucleus might be derived mainly from the superior cerebellar artery, but the anterior and posterior inferior cerebellar arteries also contributed some branches to it. These branches were found mostly 5～6 in number on the superior surface and 3～5 in number on the inferior surface.

Objective:To investigate the effect of ulinastatin on liver and kidney function in the patients with traumatic hemorrhag-ic shock. Methods:Totally 110 patients with traumatic hemorrhagic shock were divided into the control group (n=55) and the obser-vation group (n=55) according to the random number table. The control group received the conventional anti-shock treatment, and the observation group received ulinastatin with intravenous injection by syringe pump additonally. The changes of heart rate, urine vol-ume, liver function, renal function and inflammatory cytokine levels in the two groups were observed before and after the operation. Results:The heart rate at the 3rd h and 6th h after the operation in the observation group was significantly lower than that before the treatment , and urine volume was aslo significantly more than that before the treatment. The postoperative AST, ALT and LDH at the 3rd h and 6th h in the observation group were significantly lower than those in the control group at the same period, and the difference was significant (P<0. 05). The postoperative BUN, SCr andβ2-MG on the 1st day in the observation group were significantly higher than those before the surgery, and the difference was significant (P<0. 05);the postoperative BUN, SCr andβ2-MG on the 3rd day in the observation group were significantly different from those in the control group (P<0. 05). The postoperative IL-1β level on the 1st day in the observation group was significantly higher than that before the surgery (P<0. 05);the serum IL-1βlevel on the 3rd day in the observation group showed no statistically significant difference from that before the surgery (P>0. 05);the IL-6 levels on the 1st and 3rd day in the observation group were significantly higher than those before the surgery, however, lower than those in the control group with significant differences (P<0. 05). Conclusion: Ulinastatin has protective effect on liver and kidney function in the pa-tients with traumatic hemorrhagic shock, and can improve heart rate and urine output of the patients.

ObjectiveTo investigate the risk factors in ischemic stroke following total hip replacement. MethodsThe clinical data of 18 patients who suffered ischemic stroke following total hip replacement were compared with other 142 patients without ischemic stroke following total hip replacement who were randomly selected as control. ResultsThe incidence rate of ischemic stroke following total hip replacement in our hospital was 1.8%. Age,hypertension, history of stroke,falling of systolic pressure and diastolic pressure during opereration were significantly different between patients and controls(P<0.05).There was no significantly different in sex,previous cardiac diseases, diabetes, hyperlipemia,and the bleeding in operation between patients and controls(P>0.05).ConclusionAge,hypertension, history of cerebrovascular disease,falling of systolic pressure and diastolic pressure during opereration are the important risk factors of ischemic stroke following total hip replacement.

For the study of venae cerebri profundae of the Chinese, 50 previously fixed adult cerebral hemispheres and 11 brains of the newborn were investigated. The adult cerebral hemispheres were dissected under the stereoscopic microscope. All the 11 brains of the newborn were treated within 24 hours after death. Six percent gelatin solution containing 6% vermilion was injected into arteria carotis interna while a mixture of Indian ink with 3% gelatin was injected into vena jugularis interna. The specimens were fixed, sectioned into slices of 1～3 mm thick, cleared and observed under stereoscopic microscope. The findings were summarized as follows:1. vena cerebri interna was mostly formed by the continuation of v. thalamostriata superior after it curved inward and backward. In 38.00%?6.86 of the cases it united with v. choroidea superior and v. septi pellucidi at the site of the curvature. In 32.00%?6.6 it didn't receive any veins. In 12.00%?4.60 it united with v. septi pellucidi and 80.00%?3.84 with v. choroidea superior, while other occurrences were rare.In 80.00%?5.66 of the cases, Vena cerebri interna took its course at the posterior margin of the interventricular foramen. The rest started at the anterior one third (12.00%?4.60)and middle one third (8.00%?3.84) of the thalamus respectively.The source, position and course of v. thalamostriata superior, v. choroidea superior, v. septi pellucidi and v. ventriculi lateralis medialis were observed and described.2. v. basalis was formed by the union of the v. cerebri anterior, v. cerebri media profunda and v. ventricularis lateralis inferior. 70% of v. cerebri anterior emptied into v. basalis whereas the other 30% into the adjacent venous sinuses. v. cerebri media profundae, most of which received vv. thalamostriata inferior, emptied into v. basalis in 68.00%?6.60 cases and the adjacent venous sinuses in 32.00%?6.60 v. ventricularis lateralis inferior emptied into v. basalis in 96.00%?2.77 cases and into v. cerebri magna in 2.00%?1.98, while in 2.00%?1.98 it was absent.3. The longitudinal anastomotic vein. was formed by the "T" shaped bifurcations of the small branches of v. thalamostriata superior, v. septi pellucidi and v. ventricularis lateralis medialis in the white matter within an area of 2 mm by the lateral angle of the lateral ventricle. It received numerous radially arranged small veins in the medulla of the cerebral hemisphere. The longer ones of these veins might extend to the cortex and anastomoses between them and superficial cortical veins were demonstrated.

Intracortical distribution of arteries were studied on thick sections prepared from brains of 11 newborns after injection and fixation. The results are as follows.1. Branches from the cerebral arteries form a pial arterial network on the cortical surface. The larger pial arteries are supplied with vasa-vasorum and perivascular vessels. They send out cortical and medullary arteries penetrating the cortex vertically from the surface.2. The distribution of arteries in the entire cortical area can be represented by the pattern observed in a single gyrus, which serves as a general rule. The cortical arteries arising from the pial arteries penetrate into the cortex vertically and are arranged regularly which appear as a brush border that curves with the cerebral surface in sections. The diameter of the long cortical arteries is 16～31 ?m, while that of the short ones is 7.5～15.4 ?m. All these arteries send out branches at right angles which anastomose with one another to form a dense polygonal or irregular vascular network.The medullary arteries pass directly through the cortex into medulla. The diameter of the long medullary arteries is 48～61 ?m and that of the short ones, 35～47 ?m. Those entering from the top of each gyrus pass directly to the deep medulla, whereas those from the sulcus to the junction between the cortex and medulla exhibit various degrees of curvature. The medullary arteries send out branches at right angle, which, in turn, form T-shaped bifurcations, interconnecting each other in an oblong lattice framework.3. The central arteries penetrate the base of the brain, fan out and arch upward to reach the corpus striatum. Arteries may penetrate into the thalamus from posteriolateral, inferio-medial or superior surface. They branch with acute angles and form dense network with polygonal, triangular, circular and irregular interspaces. The arteries of the internal capsule also branch at right angles, show "T" bifurcations after a short distance and form an oblong vascular network.

Objective To investigate the relationship between carotid artery intima-media thickness and plasminogen activator inhibitor-1(PAI-1)in patients with metabolic syndrome(MS).Methods According to the definition of MS by NCEP-ATP Ⅲ,323 patients were divided into the MS group(160 cases)and without MS group(163 cases).The PAI-1 level was assayed by ELISA.The carotid artery intima-media thickness(IMT)and atherosclerotic plaque were measured by high-frequency Doppler ultrasound.Results The PAI-1 level,carotid IMT and incidence rate of plaque of the MS group were 30.52±11.02 ng/ml,0.92±0.21 mm and 63.1% respectively.Those of the without MS group were 26.57±11.09 ng/ml,0.86±0.20 mm and 49.1% respectively.There was a significant difference between two groups(P<0.05～0.01).Moreover,with the increasing of the number of MS components,the carotid artery intima-media thickness(IMT)and incidence rate of plaque were gradually increased(P<0.05).The stepwise regression analysis showed that PAI-1 was independently associated with the carotid IMT(standardized coefficients=0.105,P<0.05).Conclusion MS tends to cause carotid atherosclerosis,the increase of PAI-1 is possibly correlated with carotid artery atherosclerosis.
