Objective To analyze the cause of lower limbs swelling after knee arthroscopy operation, and compare the effect of gravity and pump irrigation system on lower limbs swelling after operation. Methods 60 patients after knee arthroscopic surgery were divided into the pump irrigation group and the gravity group with 30 patients in each group. We measured the perimeter of the lower limb pre and post operation and compared the operation time of each group. Results There were no significant differences in the perimeter of the lower limb and operation time between the gravity group and the pump irrigation group. Conclusions During knee arthroscopic surgery which cost less than 1 hour, there was no inlluence on lower limbs swelling whether using gravity or pump irrigation system.

This article explains four cases of professor REN Ji-xue,including anasarca,serious blepharoptosis,head cold,summer diarrhea,from which we can find the laws of syndrome differentiation by him. In which,the key point of the pathogenesis of anasarca is spleen-qi deficiency, so replenishing qi and invigorating the spleen, warming yang for diuresis are the treatment nethod for anasarca. Sinking of qi due to deficiency of spleen leads to serious blepharoptosis and Invigorating Spleen and Replenishing Qi Decoction is the main prescription. The key pathogenesis of head cold is disharmony of nutrient qi with defensive qi, so regulating ying and wei, dispersing lung qi for resuscitation are the treatment methods, and both inside and outside therapies are in use. Cold-damp invasion of spleen is the main cause of summer diarrhea, so activating qi flowing and warming spleen and stomach, dissipating dampness for stopping diarrhea are used. Professor REN Ji-xue is good at taking different method according to different key point of the pathogenesis, so the efficiency is good. This is one feature of Professor REN in treating miscellaneous diseases.

Recent studies have demonstrated that endothelial-to-mesenchymal transition ( EndMT) plays a pivotal role in the cardiovascular system, spanning cardiovascular development through to cardiovascular diseases (CVD).In this review, we describe the common signaling mechanisms that promote EndMT participating in the pathological process of CVD, and we discuss how these in-tracellular cascades participate in crosstalk to integrate cues to reverse EndMT, which potentially may provide novel therapeutic oppor-tunities for CVD.

Objective To establish the mathematical model and perform experimental mensuration on effective slice width for 4-slice spiral CT. Methods First, assuming the spiral slice sensitivity profile (SSP) was Gauss distribution, a formula about effective slice width, defined as the full width at half maximum (FWHM) of SSP, was get. Then, using Philips Mx8000 4-slice spiral CT system and the same CT technique as those used for clinical CT, CTP 528 of Phantom Catphan 500 was scanned with parameters as follows: 120 kV, 150 mAs, 180 mm FOV, 512×512 Matrix, 180° linear interpolation, different pitch and 0.5 mm detector width. Finally, FWHM was got from the coronal multiplanar reconstruction image passing by the center of tungsten ball in CTP528 for each sequence. Results With pitch of 0.500, 0.625, 0.875, 1.000, 1.250, 1.500 and 1.750, the measured FWHM was 0.7, 0.7, 0.7, 0.8, 0.7, 0.7 and 0.7 mm, respectively. With detector width of 0.5, 1.0 and 5.0 mm, the measured FWHM was 0.7, 1.2, and 6.7 mm, respectively. All the measured effective slices were higher than those of theoretical values. Conclusion The relativity between effective slice width and detector width is direct proportion, while that between effective slice width and pitch is non-linear.

Objective To explore Angptl2(angiopoietin-like protein 2)expression in tumor tis-sue and serum in patients with breast cancer(BC). Methods A total of 78 BC patients were enrolled in this study. Immunohistochemistry was used to detect Angptl2 expression in tumor and adjacent normal tis-sues. Preoperative and postoperative serum Angptl2 levels were determined via ELISA. Correlation among Angptl2 expression,clinicopathological factors and progression-free survival(PFS)were further evalua-ted. The receiver operating characteristics(ROC)curve was constructed to describe diagnostic specificity and sensitivity. Results Angptl2 was positively expressed in 64(82. 1% )cases. The rates of high and moderate expression of Angpt l2 in tumor and adjacent tissues were 53. 8%(42 / 78)and 7. 7%(6 / 78), respectively(P ﹤ 0. 001). Moreover,the elevated Angptl2 protein was significantly associated with lymph metastasis and adverse PFS. In addition,serum Angptl2 level in BC patients was significantly higher than that in benign controls[(218. 72 ± 88. 02)vs(80. 88 ± 30. 59)ng/ ml,P ﹤ 0. 01]. The area under the curve(AUC)was 0. 909,which indicated a good function for diagnosis. Postoperative serum Angptl2 level was decreased to(142. 43 ± 60. 29)ng/ ml,but still higher than that in controls(P ﹤ 0. 01). Conclusion The expression of Angptl2 may increase in tumor tissue and serum of BC and it may be a potential tumor marker for diagnosis and prognosis.

Objective To observe the clinical efficacy and safety of application of lafutidine treated in curing peptic ulcer.Methods Eighty-four patients with peptic ulcer were randomly assigned to receive either lafutidine(10 mg) twice daily in 42 patients of cured group or lansoprazole (30 mg) once daily for 4 weeks in 42 patients of control group.Ulcer healing rate and clinical performance were examined after treatment.Results The first,third and seventh day of peptic ulcer healing rate were 38.09％ (16/42), 71.42％ (30/42) and 90.47％ (38/42) in the lansoprazole group and 23.81％ (10/42), 76.19％ (32/42) and 85.71％ (36/42) in the lafutidine group.There were no siginificant difference between two groups (P =0.157,0.620, 0.736).Gastroscope examination showed the complete healing rate, average healing rate and general clinical effectiveness were 61.90％(26/42) ,30.95％(13/42) and 97.61％(41/42) in the lansoprazole group,while the number for lafutidine group were 57.14％ (24/42), 28.57％ (12/42) and 95.23％ (40/42).There were no siginificant difference between two groups (P =0.657, 0.811, 1.000).No severe side-effect was occurred in both groups.Conclusion Use Lafutidine to cure peptic ulcer can promote healing effectively, improve patients' clinical symptoms which is similar to lansoprazole.

Objective To study the feasible prophylactic proposal for the periventricular-intraventricular hemorrhage(PIVH)in preterm infants with the aim to reduce the mortality and improve the prognosis.Methods From January 2004 to June 2005,pregnant women at high risk for preterm delivery and with gestational age of less than 35 weeks and their infants were enrolled and divided into five groups randomly.Pregnant women received antenatal intramuscular or intravenously injection of vitamin K_1 10 mg per day for 2 to 7 days were Group A.Group B received antenatal intramuscular or intravenously injection of dexamethasone 10 mg per day for 1 day.Group C received antenatal intramuscular or intravenously injection of dexamethasone 10 mg per day for 2 days.Group D received dexamethasone 10 mg per day for 1 or 2 days and vitamin K_1 10 mg per day for 2 to 7 days.Infants in the phenobarbital group received intravenous injection of phenobarbital within 3 hours after birth for 3 to 5 days.Infants in the control group received neither phenobarbital after birth nor dexamethasone or vitamin K_1 injection antenatally.Results PIVH was diagnosed in 17 of 40(42.5%)in Group A,34 of 63(54.0%)in Group B,36 of 70(51.4%)in Group C,14 of 44(31.8%)in Group D,they all higher than control group(?2=15.10,P=0.004).More infants in the control group had severe PIVH(Grade Ⅲ and Ⅳ)than other groups(?2=9.527,P=0.049).The incidence of PIVH and severe PIVH in Group B and Group C were no significant difference.Furthermore,the incidence of PIVH was no difference in phenobarbital group(60.0%)and control group(65.2%)(?2=0.361,P=0.548).But the incidence of severe PIVH in phenobarbital group(5.0%)was less than control group(18.4%)(?2=4.04,P=0.044).Conclusions The combined antenatal administration of dexamethasone and vitamin K_1 can reduce the incidence of PIVH in preterm infants.Postnatal administration of phenobarbital can not decrease the incidence of PIVH,but decrease the frequency of severe PIVH.
