Objective To investigate the ureteral injury in gynecological laparoscopies and discuss its diagnosis,treatment and prevention.Methods Six cases of ureteral injury were reviewed.The clinical features including the type of diseases,uterine size,pelvic adhesion and the methods of diagnosis,treatment were studied.Results Ureteral injuries happened during laparoscopically assisted vaginal hysterectomy(LAVH). The gynecological disorders included pelvic adhesions,endometriosis and leiomyoma in cervical.Patients presented flank pain,fever,increased volumes discharge.Conclusion Ureteral injury is an uncommon and sever complication in gynecological laparoscopies.Fever,flank pain and abnormal vaginal discharge should be paid attention to be ureteral injury.

Objective To explore the changes of asphyxial neonatal gastric juice pH values,and to provide data for making early intervention measures.Methods Eighty asphyxial neonates were divided into routine group(55 cases)and intervention group(25 cases).Twenty neonates who weren't asphyxial were set as a control group.Those neonates' gastric juice pH values were monitored dynamically.The newborns in intervention group were treated by giving smecta and cimetidine intravenously on the routine treatment.The impairment occurrence conditions of these newborns' gastrointestinal functions were observed.Results The gastric juice pH values of asphyxial neonates were obviously lower than those of the control group at their birth(Pa0.05).The occurrence rate of gastrointestinal functions impairment was lowered(?2=16.0 P

OBJECTIVETo observe the effects of electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) com- bined with granisetron on nausea and vomiting as well as serum levels of 5-hydroxy tryptamine (5-HT) and dopamine (DA) in chemotherapy patients.

METHODSSeventy-two chemotherapy patients who met the inclusive criteria were randomly divided into an observation group (38 cases) and a control group (34 cases). The patients in the observation group were treated with electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron injection; the patients in the control group were treated with electroacupuncture at sham-point 1 and sham- point 2, and the rest treatment was identical to the observation group. After 3-day treatment, the clinical indices including times of vomiting and severity of nausea, etc. were observed in the two groups.

RESULTS(1) At the acute stage within 24 h, the times of vomiting in the two groups were not significantly different (P>0.05); at the delay stage, the severity of nausea was significantly higher in the control group (P<0.05). (2) As for the comprehensive efficacy and rate of complete control, there was no obvious difference between the two groups at the acute stage (P>0.05); while in the delay stage, the rate of complete control in the observation group was superior to that in the control group (P<0.01). (3) Compared before and after the treatment, serum levels of 5-HT and DA were evidently reduced in the observation group (both P<0.05), while those in the control group were not significantly changed after treatment (both P>0.05).

CONCLUSIONElectroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron could obviously relieve the nausea in chemotherapy patients at the delay stage. The effect mechanism is possibly related to reducing the content of 5-HIT nndl nA

Objective To examine the distribution of flurbiprofen axetil in cerebral-spinal fluid (CSF) by determining the CSF concentration of flurbiprofen after iv administration. Methods Seventy-two ASA Ⅰ or Ⅱ patients of both sexes aged 18-75 yr weighing 54-82 kg undergoing spinal or combined spinal-epidural anesthesia for lower extremity or lower abdominal surgery were studied. Flurbiprofen axetil 1 mg/kg was injected intravenously.CSF 2 ml and venous blood 3 ml were obtained simultaneously every 5 min after iv injection for 45 min (T1-9 ) for determination of flurbiprofen concentration using high performance liquid chromatography, and the CSF/blood flurbiprofen concentration ratio was caculated. Results Flurbiprofen was not detected in CSF at T1,2 after iv injection in 3 and 4 patients. The CSF flurbiprofen concentration was significantly higher at T4-9, and CSF/blood flubiprofen concentration ratio higher at T5-9 than at T3 ( P ＜ 0.05). There was no significant difference in CSF flurbiprofen concentrations among T4-9 ( P ＞ 0.05 ) Conclusion Flurbiprofen is detected in CSF after iv injection, the CSF flurbiprofen concentration peaks at 20 min after iv injection and it lasts until 45 min after iv injection.

AIM: To study the curative effect for patients with age related cataract and shallow anterior chamber after phacoemulsification.METHODS: Totally 38 patients (38 eyes) with age related cataract and shallow anterior chamber were selected and divided into two groups according to the depth of the anterior chamber, as mild shallow anterior chamber group (2-2.5mm) 23 eyes, high risk shallow anterior chamber group (<2.0mm) 15 eyes.Thirty-eight patients (38 eyes) with age related cataract with normal anterior chamber were as control group at the same period.All the patients received the operations by the same doctor and were followed up for 3mo.The observed items included visual acuity before and after operations, intraocular pressure, anterior chamber depth, corneal endothelial cell density and complications.RESULTS: There were no significant difference on visual acuity, intraocular pressure and corneal endothelial cell density between the two groups before operations (P>0.05).The visual acuity improved significantly after operation in both groups (P<0.05).Intraocular pressure after operation decreased significantly in both groups (P<0.05).Anterior chamber depth increased significantly after operation in both groups (P<0.05).Corneal endothelial cell density decreased significantly in both groups (P<0.05).There were no significant difference on anterior chamber depth, intraocular pressure and corneal endothelial cell density between the two groups at different time point after operations (P>0.05).Posterior capsular rupture occurred in shallow anterior chamber group in 1 eye, suspensory ligament rupture in 1 eye.Posterior capsular rupture and suspensory ligament rupture occurred none in normal anterior chamber group.Postoperative corneal edema occurred in 10 eyes (26%) in shallow anterior chamber group, which occurred in 3 eyes (8%) in normal anterior chamber group.The difference on the incidence was significant (P <0.05).CONCLUSION: Phacoemulsification should be taken timely for patients with age related cataract and shallow anterior chamber.The postoperative visual acuity can be improved and the anterior chamber depth can increase.The operation is safe and effective for those patients.

Objective To investigate the medial-lateral tilting of patella in two different coordinate systems before and after total knee arthroplasty (TKA). Methods Six fresh-frozen left low limbs from cadaver were tested using a modified Oxford Rig. Anatomically based multiple loading of the quadriceps mechanism was applied(Vastus medialis 24.5 N, Vastus intermedius/rectus femoris 29.4 N, Vastus lateralis 19.6 N). In a three dimensional coordinate system, patellar tilting was tracked using a custom-made Laser tracking device. The femoral trochlea was used as the other coodinate system in skyline view of patellar-femoral joint. Total knee arthroplasty was performed using PFC? posterior cruciate ligament substituting knee system. The tilting angles of patellar were measured before and after TKA. Results In three dimensional coordinate system, when knee flexed 30?,60?,90?,120?,150?, the patella titled :-3.10??2.25?,2.50??1.07?,5.46??2.60?,6.32??2.16?,-2.10??1.90? respectively before total knee arthroplasty was undertaken. After total knee arthroplasty, the patella tilted 3.24??0.35?,2.30??1.39?,1.65??1.17?,1.29??1.03?,-0.86??1.42? respectively. When femoral trochlea was taken as coordinate, the patella tilted 0??0?,0??0?,0??0?,0.24??0.35?,-3.21??1.80?; 0??0?,0??0?,0??0?,0??0?,-1.12??1.20? respectively both before and after TKA (Lateral patella tilting was defined as positive and medial patella tilting, negative). Conclusion Even the relationship between patella and femoral trochlea remains normal, the mode and magnitude of patellar tilting changes significantly after TKA. In early flexion of knee joint, patella tilts medially before TKA while it tilts laterally after TKA. After TKA, patella tilts less laterally than it does before TKA when a knee flexes from 60 to 120 degrees.
