Retrospective analyses were performed for the clinical data of 67 patients with biliary calculi.Among them,laparocholedochoscopy plus holmium laser lithotripsy (n =31) and laparocholedochoscopy (n =36) were performed.As compared with laparocholedochoscopy,early postoperative serum inflammatory mediators of holmium laser lithotripsy were obviously lower,biliary pressure dropped faster and less volatile[(8.5±1.5)-(12.2±4.1) vs.(8.1 ±1.6)-(16.5±4.7) mmHg(1 mmHg=0.133 kPa)],operative duration [(93.5 ± 13.4) vs.(127.6 ± 34.5) min],conversion into laparotomy rate[3％ (1/31) vs.11％ (4/36)],postoperation SIRS rate[23％ (7/31) vs.42％ (15/36)],length of hospital stay [(8.5 ± 3.5) vs.(12.6 ± 3.9) days] and postoperative biliary residual stones rate [0％ (0/31) vs.8％ (3/36)]were also better than.

Objective To investigate the effect of obesity on the early complications after esophageal cancer operation.Methods Clinical data of 327 patients who had esophageal cancer operation in our hospital from August 2012 to September 2015 were retrospectively analyzed.The patients were divided into 4 groups:lean group(n =75), normal group(n =120),overweight group(n =103)and obesity group(n =29)by body mass index(BMI).The impact of obesity on early complications of esophageal carcinoma after surgery was analyzed.Results The operation time of the lean group,normal group,overweight group and obesity group were (257.8 ±52.6 )min,(289.3 ± 48.7)min,(321.5 ±55.9)min,(367.9 ±50.2)min respectively.The operation time was increased with the increase of BMI (F =13.397,P =0.000).The incidence rates of incision infection,empyema,hoarseness,diaphragmatic hernia,postoperative bleeding,chylous fistula,pulmonary complication were 5.3%,1.3%,1.3%,1.3%,2.7%, 2.7%,16.0% in the lean group,5.0%,1.6%,1.6%,1.3%,1.6%,1.6%,17.5% in the normal group,5.8%, 1.9%,0.9%,1.9%,1.9%,1.9%,1.9% in the overweight group,10.3%,3.4%,0.0%,3.4%,3.4%,0.0%, 13.8% in the obesity group.No significant differences were found about the hospital days,wound infection,empyema, hoarseness,diaphragmatic hernia,operation hemorrhage,chylous fistula,pulmonary complications among the 4 groups (all P >0.05 ).The incidence rates of cardiovascular complications and anastomotic leakage after operation were 0.0%,4.0% in the lean group,1.9%,5.0% in the normal group,6.8%,9.7% in the overweight group,13.8%, 17.2% in the obesity group.The incidence of cardiovascular complications,postoperative anastomotic leakage increased with the increase of BMI.The differences of the four groups were statistically significant(F =1.675,1.054, all P <0.05).Conclusion Obesity can increase the incidence of early postoperative complications in patients with esophageal cancer.But obesity is not a contraindication of surgery for esophageal cancer,but obese patients should be more carefully treated in the perioperative period.

Pulse wave, a research focus in both traditional Chinese medicine and Western medicine, which contains a wealth of human physiological and pathological information, has always been the concern of medical practitioners. On the basis of the review on the development of the pulse wave theory and its applications, the existing problems in this field are discussed in this paper. On the basis of the status quo of pulse wave information extraction methods and the utilization of pulse wave in traditional Chinese and Western medicine, a more in-depth study on pulse wave is proposed to make it a bridge connecting traditional Chinese medicine with Western medicine.

Objective To observe the effect of medicine-induced posterior vitreous detachment (PVD) on proliferative vitreoretinopathy (PVR).Methods.PVR was induced in the left eyes of 24 pigmented rabbits by intravitreal injection with platelet rich plasma.The rabbits were randomly divided into two experimental groups (group A and B) and one control group with 8 eyes in each group.Three hours later,the eyes in group A and B and the control group underwent intravireal injection with 1 U plasmin 0.05 ml+ 20 U hyaluronidase 0.05 ml,plasmin 0.1 ml,and balance salt solution 0.1 ml,respectively.The grade of PVR was recorded 1,7,and 28 days after the intravitreal injection,and the eyes were examined by flash electroretinogram (FERG),B-scan,and retinal histopathological examination.Results The PVR models of rabbit eyes were induced successfully.On the 7th day after injection,complete and partial PVD was found in 5 and 3 eyes respectively in group A;partial PVD in 5 eyes and no complete PVD was observed in group B;there was no PVD in the other 3 eyes in group B and also in the eyes in the control group.On the 28th day after intravitreal injection,PVR grade of group A and B were both obviously lower than that of the control group(D= 75.6,98.9;P = 0.003,P = 0.011) ;On the 7th and 28th day after injection,the b-wave amplitude in group A and B was significantly higher than that in the control group;PVR grade of the PVD eyes was lower than that of non-PVD eyes;PVR grade of the complete PVD eyes was only 0 ～ 1.Conclusions Three hours after the PVR models of rabbit eyes were induced,complete PVD induced by intravitreal injection of plasmin combined with hyaluronidase could prevent the development of PVR of rabbit eyes in some degree;partial PVD induced by plasmin alone or combined with hyaluronidase could relieve the development of PVR.

Objective To study the role of serum C-reactive protein (CRP) ,supplement C3 and CA in sys-temic inflammatory response syndrome (SIRS) induced by acute cerebral infarction(ACI).Methods The levels of CRP,C3 and CA were measured by automatic immunoturbidimetry in 52 ACI cases accompanied with SIRS (SIRS group) ,50 cases of acute simple cerebral infarction(SACI group) and 46 normal cases (control group).Results The serum CRP, C3 ,and CA levels were significantly different among the three groups( F=720.6,580.8,94.1 ,P <0.01) ,the serum CRP levels in SIRS group were significantly higher than those in SACI group(P <0.01 ).The ser-um C3 and CA levels in SIRS were significantly lower than those in SACI group(P <0.01).With the diagnosis crite-rion items increasing, the serum CRP levels tended to be higher (t = 7.69 ,P < 0.01 ), and the serum C3, CA levels tended to be lower meeting SIRS diagnosis criterion numbers increasing respectively (t=10.68 and 10.53, P <0.01).Conclusion The serum ClIP levels are higher significantly and the serum levels of C3 and C4 are lower sig-nificantly when ACI progresses to SIRS.The serum CRP,C3,CA level changes can be used as an index for judging the progress of ACI progressed to SIRS.

Objective To discuss the prenatal diagnosis of abnormalities of fetal limb bone.Methods We selected 18 cases which long bone of fetus less than 2SD of average volume of gestational weeks or long bone changed into angle or other fetus's abnormalities by first B-mode ultrasonic. All above cases was delivered at Capital Medical University of Obstetric and Gynecological Hospital during Jan. 2006 to Dec. 2009. We B-mode ultrasonic was used to measure fetus's biparietal diameter (BPD) ,femur length (FL) ,abdominal circumference(AC) ,head circumference(HC) ,humerus length (HL) ,amniotic fluid index (AFI) and structures of organ and calculated FL/AC, growth speed of long bone. The standard of achondroplasia is that FL and HL are less than 4SD of average of gestational weeks or FL/AC less than 0. 16. The standard of Osteogenesis Imperfecta is fetal long bone of fetus shows short and thick, curves into angle, fracture in uterus by X-ray, or skull shows thin or sink by X-ray. Results (1) By B-mode ultrasonic and X-ray exam of all 18 cases: 7 cases shows that HC ＞2SD, 10 cases shows too much amniotic fluid, 12 cases shows AFI ＞ 18.0, 9 cases shows abnormalities of narrow cavitas thoracis, disordered vertebral column, or unusual architecture of heart. For cases 1 to 14 are achondroplasia, among which,11 cases are FL＜4SD and HL＜4SD, 2 cases are FL ＜3SD and HL ＜4SD, 1 case is not only FL ＜2SD and HL ＜3SD but also hydroncus all over the body of fetus. The growth velocity of long bone of fetus in all the 14 cases is more slowly than the normal rate. For all the above 14 cases, 12 cases FL/AC ＜0. 16, 1 case FL/AC =0. 19, 1 case FL/AC =0. 20. The length of femur or humerus is shorter than the normal rate and have other abnormalities the above last two cases. For case 15 and 16, they don't show any abnormalities of bone growth though one year's follow up studying. For case 17 and 18, they are osteogenesis imperfecta. (2) The result of fetal perinatal period fate and autopsy: there are 8 female and 10 male in all the 18 cases. One case is labored after 39 weeks pregnancy, and it is low birth weight infant, weight ＜3%th. All the other cases are normally birth weight infant. All the 18 cases of abnormalities of fetal limb bone are examined by chromosomes check, among which, 9 cases are amniocentesis, 7 cases are cordocentesis,2 cases are checked chromosomes by fetus cord blood, all the caryotype are normal. In the 16 autopsy cases,14 cases are achondroplasia or hypochondroplasis. It can be seen amplifying extremities, hyperplasia chondrocytes of tubiform born, karyomegaly, anachromasis, hyperplasia capillaries though microscope and grow up into cartilage irregularly. Also can be seen hyperplasia chondrocytes of epiphyses, delaying osteosis.2 cases are osteogenesis imperfecta. It can be seen broadening of metaphyses, exility of bone trabeculae. For the other two cases which the fetus is alive, we do the follow up studying to their one year old one of them is low birth weight new born, their limb and height are all normal. Conclusions To diagnose fetal Achondroplasia, it is not only based on the significantly shorter of femur or humerus length but also based on the dynamics observing the long bone growth velocity and calculating FL/AC. For osteogenesis imperfecta fetus, it should be diagnosed by fractures in uterus though X-ray.
