12100 cases of induced abortion in our hospital from January 1986 to December 1988 were divided in five groups according to pregant days: The depth of uterine cavities; the weight of embryonoid tissue and the mean of bleeding volume in the operations. Results showed that bleeding in the operation was significantly increased with the progreses of pregnancy (P

Objective To study the influence of the rupture of anterior cruciate ligament(ACL) on the menisci. Methods Four hundred and nineteen consecutive patients with rupture of ACL during December 1984 to December 1999 were included in this study. The incidence of meniscal injuries and the correlation of injuries of menisci and cartilage were investigated. Results The incidence of meniscal injuries was increased from 55.6% in acute to 74.1% in sub chronic and 89.8% in chronic. There were significant differences between each two stages (P

In order to explore the causes and nursing care of gastroesophageal reflux in patients with ceryical vertebra frac-ture and paraplegia,the clinical data of 79 patients were retrospectively analyzed. Among which,31 patients suffered from gas-troesophngeal reflux. The main causes of gastroesephageal reflux were improper body position,gastrointestinal dysfunction,con-sciousness disorders,lnappropriate nasngastric feeding,drng adverse reaction,inappropriate feeding time,lack of knowledge in nurse aids and family members. It is suggested to take proper body position,assess gastrointestinal functions,implement naso-gastric feeding correctly,observe patient carefully to detect gastroesophageal reflux as early as possible,as well as provide health education for the nurse aids and family members to prevent gastroesophageal reflux and complications.

Objective:To evaluate the change in hamstring ( H ):quadriceps ( Q ) ratio following anterior cruciate ligament ( ACL) rupture during isokinetic knee extension and flexion at 30 degrees of flexion which is important for knee dynamic function .Methods:A study was performed in 25 male com-plete unilateral ACL ruptures .Isokinetic concentric and eccentric quadriceps and hamstring muscle tests in both the deficient knees and intact knees were performed at 60°/s, respectively.At 30 degrees of flexion, the average torque of quadriceps and hamstring , Qe∶Qc ratios ( ratios of eccentric quadriceps to concentric quadriceps muscle torque ) , He∶Hc ratios ( eccentric hamstring to concentric hamstring ) , Hc∶Qc ratios ( concentric hamstring to concentric quadriceps ) , He∶Qc ratios ( eccentric hamstring to con-centric quadriceps ) , and Hc∶Qe ratios ( concentric hamstring to eccentric quadriceps ) were calculated . Wilcoxon matched-pairs signed-ranks test was used .Results:At 30 degrees of knee flexion , a significant reduction ( P<0.05) in the average torque of quadriceps was observed at concentric and eccentric 60°/s produced by the deficient-side compared with the intact side .In addition, Hc∶Qc, He∶Qc, and Qe∶Qc significantly increased on the ACL-deficient side .Conclusion:The change in H ∶Q ratio in the mode of isokinetic 60 °/s at 30 degrees of knee flexion might therefore be a new tool to objectively document muscle function in ACL-deficient knee .

Objective To compare the expression of leukemia inhibitory factor (LIF), interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) in tissue and fluid samples from patients with endometriosis, and investigate whether LIF and IL-6 regulate VEGF in human endometriotic stromal cells (ESC). Methods The levels of VEGF, LIF, IL-6 in serum, peritoneal fluid of patients with and without endometriosis were measured by ELISA. The mRNA of these three factors in the ectopic and eutopic endometrial tissue and stromal cells were measured by real-time PCR. ESC derived from ovarian endometriomas were cultured using the method of primary cell culture with LIF and IL-6, and the level of VEGF mRNA and protein were measured by the method of real-time PCR and ELISA respectively.Results VEGF and IL-6 concentration were 1.2 and 1.3 times higher in the serum of patients with endometriosis than in the control group [(94±19) versus (78±17) ng/L; (45±14) versus (35±9) ng/L; all P<0.05]. VEGF and IL-6 concentration were 1.2 and 1.4 times higher in the peritoneal fluid of patients with endometriosis than in the control group [(110±25) versus (91±21) ng/L; (69±20) versus (49±15) ng/L; all P<0.05]. VEGF and IL-6 concentrations in peritoneal fluid of patients with endometriosis were 1.2 and 1.5 times higher than in serum (all P<0.01). VEGF, LIF and IL-6 mRNA expression were 2.2, 8.6, 44.7 times higher in ESC compared with the matching eutopic endometrial stromal cells (all P<0.01). LIF and IL-6 mRNA were 2.0 and 64.8 times higher in ectopic endometrial tissue than the matching eutopic endometrial tissue (all P<0.05).ESC cultured with LIF, IL-6 and LIF+IL-6 induce VEGF protein secretion [(106±18), (124±30), (140±27) ng/L] by 1.3 , 1.5 and 1.7 times (all P<0.05). Conclusion Overexpression of LIF and IL-6 may synergistically contribute to upregulation of VEGF in ESC and promote development of endometriosis.

Objective:To investigate the diagnosis, treatment and prognosis of ureteral endometriosis with hydronephrosis.Methods:A retrospective study was performed of 92 cases diagnosed as ureteral endometriosis with surgery confirmed in Peking University First Hospital from January 2000 to January 2021.Results:The incidence of ureteral endometriosis was 0.9% (92/10 222), with an average age of (40.0±6.0) years. Among 92 cases, urological symptoms and pelvic pain including dysmenorrheal, periodic abdominal pain were the main forms of clinical characteristics, while 11 patients (12%, 11/92) were asymptomatic. All patients with ureteral endometriosis had hydronephrosis and hydroureter before surgery, hydronephrosis were left sided in 48 (52%, 48/92) patients, right sided in 39 (42%, 39/92) patients, both sided in 5 (5%,5/92) patients. The distal and middle sections of ureteral obstructions existed in 73 (79%, 73/92) patients and 19 (21%, 19/92) patients, respectively. Out of the 92 ureteral lesions 71 (77%, 71/92) patients were extrinsic lesions, 21 (23%, 21/92) patients presented intrinsic lesions. Of the 38 cases who took preoperative radionuclide renal dynamic imaging examination, there were 6 (16%, 6/38) cases of mildly damaged, 7 (18%, 7/38) cases of moderately dameged, 14 (37%, 14/38) cases of severely damaged, and 11 (29%, 11/38) cases of normal renal function. Laparotomy was decided in 25 (27%, 25/92) patients, and laparoscopic surgery in 67 (73%, 67/92) patients. In cases of ureteral surgery, ureterolysis, partial ureteral resection and ureterocystoneostomy, partial ureteral resection and end-to-end ureteral anastomosis and nephroureterectomy were undertaken in 52 (57%, 52/92), 20 (22%, 20/92), 12 (13%, 12/92) and 8 (9%, 8/92) patients separately. The median follow up was 108 months (range: 6 to 240 months). During the follow-up period, 68 (87%, 68/78) patients took urinary ultrasound after surgery, and 60 (88%, 60/68) cases of hydronephrosis disappeared, and 8 (12%, 8/68) cases were better than before.Conclusion:Most of the patients with ureteral endometriosis are impaired with renal function, and early surgical treatment could effectively relieve urinary obstruction and promote the recovery of renal function.

Objective:To measure the coagulation function of patients with adenomyosis so as to explore its relationship with increased menstrual amount and its clinical significance.Methods:From January 2014 to May 2019, clinical data of patients with hysterectomy in which 111 pathologically diagnosed adenomyosis (case group) and 115 with uterine myoma (control group) in Peking University First Hospital were retrospectively analyzed. The changes in coagulation function of the two groups were compared, and the correlation between coagulation and uterine volume in the adenomyosis group was analyzed.Results:(1) The activated partial thromboplastin time (APTT) was longer in the adenomyosis group than that in the uterine myoma group [(30.4±3.1), (29.6±2.5) s, respectively; P<0.05], while the thrombin time (TT) was shorter than that in the control group [(14.2±1.2), (14.6±1.0) s, respectively; P<0.05]. (2) According to the results of the Pearson correlation test, there was a positive correlation between prothrombin time (PT; r=0.135, P=0.042) and fibrinogen (FIB-C; r=0.139, P=0.036). (3) Platelet counts were higher in the anemia group of adenomyosis than that in the non-anemia group [(323±79)×10 9/L, (274±56)×10 9/L, respectively; P<0.05]. (4) FIB-C in non-anemia group of adenomyosis was lower than non-anemia group of uterine myoma [(2.8±0.5), (3.0±0.6) g/L, respectively; P<0.05], the anemia group of adenomyosis shortened TT compared with the anemia group of uterine myoma [(14.4±1.2), (15.2±0.9) s, respectively; P<0.05]. Conclusion:Patients with adenomyosis have abnormal coagulation function, which may be related to the increase amount of menstruation, and anemia may also be involved in coagulation disorders.

Objective To evaluate the effects of parthenolide on estradiol?synthesizing enzyme, steroidogenic acute regulatory protein (StAR), and ER isoforms,VEGF in human endometriotic stromal cells. Methods Primary endometriotic stromal cells were treated with different concentrations (1, 5, 10 and 20 μmol/L) of parthenolide. The mRNA of StAR, ER isoforms (ERα and ERβ), PR, vascular endothelial growth factor (VEGF), interleukin?6 (IL?6), tumour necrosis factor?α (TNFα), tumour necrosis factor receptor (TNFR) 1, TNFR2 were measured by real?time PCR. The levels of estradiol and progesterone in the cell supernatant were measured by ELISA. Results Different concentrations of parthenolide could up?regulate the mRNA of StAR in primary endometriotic stromal cells (F=5.722, P<0.05); the mRNA of StAR in the group of 20 μmol/L was significantly higher than that of the control group [2.6 ± 0.3 versus 1.0, P<0.01]. Different concentrations of parthenolide could down?regulate the mRNA of ERα (F=6.921, P<0.01); the mRNA of ERα in the group of 20 μmol/L and 10 μmol/L were significantly lower than those of the control group [0.2 ± 0.3 versus 0.3 ± 0.3 versus 1.0, all P<0.05]. Different concentrations of parthenolide could down?regulate the ratios of ERα/ERβ mRNA levels (F=4.209, P<0.05). Different concentrations of parthenolide could up?regulate the mRNA of VEGF and TNFR1 (F=10.964, P<0.01; F=7.286, P<0.01). There were no statiscal significances with different concentrations of parthenolide on the mRNA of ERβ, PR, IL?6, TNFα and TNFR2, and the levels of estradiol and progesterone in the cell supernatant (all P>0.05). Conclusions Parthenolide may regulate the expression of estradiol?synthesizing enzyme, ER isoforms and angiogenesis in endometriotic stromal cells. Parthenolide may promote the development of endometriosis.

OBJECTIVE: To study the polymorphism of human platelet antigen (HPA) system 10 among ethnic Han Chinese from Shandong, China so as to supplement the data of platelet donor bank in the region. METHODS: Peripheral blood samples of platelet donors from the region were genotyped for HPA-10 alleles by PCR-sequence specific primer (PCR-SSP) and direct sequencing. RESULTS: Among 1401 donors, a rare heterozygote carrier of HPA-10w (a+b+) was identified, which gave an allelic frequency of approximately 0.035%. CONCLUSION The detection of rare HPA-10bw antigen allele among ethnic Han Chinese from Shandong is useful for the diagnosis and prevention of neonatal alloimmune thrombocytopenia and post-transfusion purpura in the region.
