ABSTRACT

Objective:To compare the efficacy and safety of retroperitoneal laparoscopic adrenalectomy (RLA) and transperitoneal laparoscopic adrenalectomy (TLA) in the treatment of localized adrenocortical carcinoma (ACC).Methods:The data of 22 patients with stage Ⅰ/Ⅱ ACC underwent laparoscopic adrenalectomy in our institution from January 2009 to December 2018 were retrospectively analyzed. According to the different surgical approaches, these patients were divided into RLA and TLA groups. Eleven patients underwent RLA and 11 patients underwent TLA. There were no significant differences between the RLA group and the TLA group in terms of age at first diagnosis[44 (35, 54) vs. 46(41, 55) years, P= 0.793], sex (male/female: 3/8 vs. 4/7, P = 1.00), secreting tumor ratio (3/11 vs. 4/11, P = 1.00), tumor location (left/right: 6/6 vs. 7/4, P = 1.00), with hypertension or diabetes mellitus (4/11 vs. 3/11, P = 1.00). However, RLA has significantly smaller tumor size [3.0(2.5, 8.4) cm vs. 7.7(5.2, 8.4)cm, P= 0.001], and more stage Ⅰ patients [90.9%(10/11) vs. 18.2%(2/11), P=0.002], compared with those in TLA group. The perioperative indicators and oncology prognosis outcomes were collected and compared between the two groups. The Kaplan-Meier method was performed to calculate the overall survival (OS) and disease-free survival (DFS). Results:Compared with TLA, RLA had shorter operation time[90(70, 100) vs. 110 (90, 120) min, P = 0.005] and postoperative drainage tube removal time [2 (2, 3) vs. 3 (2, 6) day, P = 0.002), and the difference was statistically significant. In the TLA group, one patient was converted to open operation due to intraoperative tumor capsule rupture. For postoperative complications, one patient in the TLA group suffered with wound infection. There were no perioperative deaths in either group. All postoperative pathological examinations confirmed ACC, and there was no significant difference in Ki-67 index between the two groups [10%(3%, 35%) vs. 10%(9%, 25%), P = 0.484]. The median follow-up was similar in the two groups [48(26, 98) vs. 31(18, 49) months, P=0.237]. The local recurrence and metastasis rates were 36.4% for RLA group and 63.6% for TLA group ( P = 0.395). Survival analysis showed no statistically significant difference in DFS [5-year DFS rate: 33.6% vs. 73.2%, P = 0.118] between the two groups. The 5-year OS rates for RLA group versus TLA group were 58.3% vs. 45.5% ( P=0.485). Conclusions:For localized (stage Ⅰ/Ⅱ) ACC, both RLA and TLA seem safe and feasible, based on the similar long-term oncological prognosis. However, compared with TLA, RLA has the advantage of shorter operation time and postoperative drainage tube removal time. Due to the small number of cases included in this study, further multi-center, large-sample studies are required to demonstrate clear benefit of one surgical approach in the future.

ABSTRACT

Objective:To explore the predictive value of transvaginal ultrasound measurement of cervical length (CL) in the first and second trimester on spontaneous preterm birth in singleton pregnant women.Methods:This study retrospectively recruited 2 254 singleton pregnancies without severe comorbidities at Peking University First Hospital from January 2019 to June 2019. CL was measured for all subjects using transvaginal ultrasound in the first (11-13 +6 weeks) and second trimester (21-23 +6 weeks). Differences in CL between women with preterm (preterm group) and full-term delivery (full-term group) as well as the CL during the first and second trimester were compared. The independent risk factors for preterm birth and the predictive value of CL in the first and second trimester for spontaneous preterm birth were also explored. Fisher's exact test, t-test, χ2 test, and logistic regression analysis, etc, were adopted for statistical analysis. Results:(1) For the 2 254 subjects, CL measured in the first trimester and second trimester were (36.1±4.2) mm (22.4-52.6 mm) and (36.9±5.3) mm (2.9-59.7 mm), respectively. The incidence of short cervix in the first trimester and second trimester were 0.31% (7/2 254) and 1.46% (33/2 254), respectively. When CL was ≤25.0 mm ( OR=43.92, 95% CI:6.83-282.49) or >25.0-≤30.3 mm ( OR=6.59, 95% CI:1.97-22.0) in the first trimester, the risk of short cervix increased in the second trimester (both P<0.05). (2) The total incidence of preterm delivery was 3.06% (69/2 254). CL and the incidence of short cervix did not differ significantly in the first trimester between the preterm and full-term group [(35.2±4.5) and (36.1±4.1) mm, t=-1.78, P=0.076; 1.5% (1/69) and 0.3% (6/2 185), χ 2=2.98, P=0.084]. Compared with the full-term group, CL was shorter and the incidence of short cervix was higher in the second trimester in the preterm group [(33.6±6.7) vs (37.0±5.2) mm, t=-5.12;8.7% (6/69) vs 1.2% (27/2 185), χ 2=25.80, P<0.001]. (3) Multivariate regression analysis showed that age ≥35 years ( OR=2.05, 95% CI:1.22-3.46), history of spontaneous preterm birth ( OR=25.25, 95% CI:5.01-127.28), conception assisted by reproductive technology ( OR=10.39, 95% CI:2.39-50.33), and short cervix during the second trimester were independent risk factors for premature delivery. (4) There was no significant difference in the risk of preterm delivery when comparing to those with CL≤25.0 mm, >25.0-≤30.3 mm, >30.3-≤33.0 mm, >33.0-≤35.7 mm, >35.7-≤38.7 mm women with CL>38.7 mm during the first trimester (all P>0.05). The risk of premature delivery was relatively increased for those with CL≤25.0 mm,>25.0-≤29.5 mm, >29.5-≤33.6 mm, >33.6~≤36.8 mm, >36.8~≤40.1 mm during the second trimester compared to those with CL>40.1 mm [ OR (95% CI):17.64 (4.99-62.32), 6.89 (2.11-22.55), 3.58 (1.34-9.59), 4.04 (1.58-10.32), 3.34 (1.28-8.67), respectively , all P<0.05]. (5) When CL≤25.0 mm and ≤29.5 mm in the second trimester were used as the cut-off value, the prediction of preterm delivery was with a sensitivity of 8.70% and 17.39%, specificity of 98.80% and 95.29%, positive predictive value of 18.20% and 10.43%, negative predictive value of 97.16% and 97.34%, and the accuracy rate of 96.01% and 92.90%, respectively. Conclusions:There were no significant differences in CL and the incidence of short cervix during the first trimester among women with preterm or full-term delivery. CL in the first trimester is not an independent risk factor for preterm birth, but the risk of short cervix in the second trimester is increased when CL≤30.3 mm in the first trimester. The shorter the cervix during the second trimester, the greater the risk of preterm birth.

ABSTRACT

Objective:To analyze the clinical characteristics of rare adrenal angiomyolipoma.Methods:Clinical data of 5 patients with adrenal angiomyolipoma admitted to West China Hospital of Sichuan University from April 2009 to April 2019 were retrospectively analyzed. There were 2 males and 3 females. Age ranged from 40 to 57 years old, with an average of 46.7(40-57) years old. Clinical manifestations included right upper abdominal mass in 1 case, pain in the lower back in 1 case, and no significant symptoms were found in the rest. One patient was complicated with hypertension, one patient was complicated with decreased activities of epinephrine, norepinephrine and renin activity (orthosis), and the other patients had no abnormal hormones. 2 patients underwent abdominal ultrasound with " strong echo mass in adrenal area" , and all underwent enhanced abdominal CT with " space occupying lesion in adrenal area" , which was specifically manifested as tumors with mixed density in fat, blood vessels, muscle and so on. The average tumor diameter was 5.8(2.3-9.1) cm, including 2 cases on the left, 3 cases on the right, and 1 case with renal angiomyolipoma. All patients underwent laparoscopic adrenal tumor resection.Results:All the 5 patients underwent surgical resection successfully and were diagnosed as adrenal angiomyolipoma by pathological examination of tumor specimens after surgery. There was no significant change in blood pressure level of patients with hypertension after surgery. Follow-up time was 2-7 years and no recurrence.Conclusions:Adrenal angiomyolipoma is an extremely rare benign nonfunctional disease, which is more common in middle age. Most of the patients had no clinical history and signs. The tumor has no hormone secretion function and can be basically diagnosed with CT and other imaging examinations. The final diagnosis depends on pathological examination. After operation, the prognosis of adrenal angiomyolipoma is good.

ABSTRACT

Objective:To investigate the relationship between thyroid iodine uptake rate, 99Tc m imaging and treatment of Graves' hyperthyroidism with 131I. Methods:132 patients with Graves' hyperthyroidism were analyzed retrospectively. According to the difference of thyroid 24-hour iodine uptake rate, they were divided into group A (≤50%), group B (50%-80%) and group C (≥80%). According to the trend of iodine uptake rate curve, they were divided into peak advance group (6 h/24 h iodine uptake rate ratio >1) and non-peak advance group (6 h/24 h iodine uptake rate ratio≤1). Thyroid 99Tc m imaging was divided into three groups according to quality, including group 1 (≤30 g), group 2 (30-60 g) and group 3 (≥60 g). The therapeutic effects of 131I in different types of patients were compared. Results:132 patients were followed up for 6 months after the first 131I treatment. The total effective rate, total cure rate and uncured rate were 88.6%(117/132), 78.0%(103/132), 22.0%(29/132), respectively. The serum thyroxine levels of patients with different 24-h iodine uptake rates in the three groups after treatment were significantly lower than those before treatment ( P<0.05). The lower the 24-h iodine uptake rate of thyroid, the more significantly the serum total triiodothyronine (TT3), total triiodothyronine (TT4), free triiodothyronine (FT3) and free thyroxine (FT4) levels decreased after treatment, the more obvious the increase of thyroid stimulating hormone (TSH), and the more obvious the treatment effect ( P<0.05). The cure rate (13/29, 44.8%) in the peak advance group was significantly lower than that in the non peak advance group (90/103, 87.4%), with statistically significant difference (χ 2=23.899, P<0.001). There was significant difference in the cure rate among the three groups with different thyroid 99Tc m imaging quality (χ 2=15.502, P<0.001). Conclusions:With the increase of thyroid mass, the higher the 24-h iodine intake rate, the more obvious the peak shift, the lower the cure rate, the higher the non-healing rate, and the lower the incidence of hypothyroidism.

ABSTRACT

Adrenal vein sampling (AVS),as the gold standard of subtype diagnosis for primary aldosteronism,can directly detect the hormone concentration in adrenal vein by adrenal vein cannulation.Adrenal tumor can be categorized into no function adenoma,adrenal carcinoma,aldosterone producing adenoma (APA),cortisol producing adenoma (CPA) and pheochromocytoma.Traditionally,peripheral blood hormone testing and image examination were performed to make functional diagnosis of adrenal tumor,which exhibits low specificity and sensitivity.On the contrary,AVS can help make a distinct lateralization diagnosis according the aldosterone concentration of each gland,even in the condition of bilateral adrenal tumor and early stage tumor,which is difficult to make functional lateralization diagnosis by traditional methods.AVS can be categorized into simultaneous sampiing and sequencing sampling,according to the order of sampling.According to using adrenocorticotropic hormone (ACTH) or not,AVS can be categorized into no stimulus sampling and post-stimulus sampling.

ABSTRACT

Objective To investigate the effects of preoperative 8 am plasma total cortisol level (PTC) on the prognosis of adrenocortical carcinoma (ACC).Methods A total of 44 patients from January 2009 to October 2017 with ACC were included,PTC level within one week before surgery,clinical and pathological data were collected.The mean age of the patients was (45.2 ± 15.2) years.There were 27 females and 17 males.The mean tumor diameter was (63.6 ± 20.7) mm.There were 20 cases with functional ACC,in which 18 patients presented symptoms associated with Cushing syndrome.According to ENSAT stage,9 patients were staged as stage Ⅰ,and 35 were staged as stage Ⅱ.The median pre-operative 8 am PTC was 572.6 nmol/L,range from 89.3 to 1 118.7 nmol/L.Open adrenalectomy was employed in 23 patients and laparoscopic approach in 21 patients.The optimal cut-off value of pre-operative PTC was determined by receiver operating characteristic curve (ROC) and patients were divided into two groups with high PTC and low PTC values.Kaplan-Meier method was used to draw the survival curve,univariate and multivariate Cox regression were used to explore factors influencing the prognosis of ACC patients.Results The median follow-up duration was 42 months,range from 3-104 months.The optimal cut-off value was determined as 476.2 nmol/L,baseline and clinic-pathologic characteristics differences between two groups were not statistical significant (P > 0.05).The overall survival (OS) in the high PTC group was shorter than that in the low PTC group [median 18months (20-104 months) vs.40 months (5-98 months),P =0.014],and the recurrence free survival (RFS) of patients in the high PTC group was also shorter than that in the low PTC [median 26 months (0-104 months) vs.50 months (5-98 months),P =0.028).In univariate analysis,age,gender,tumor stage,preoperative PTC,and symptoms were correlated with postoperative OS and RFS (P < 0.05).After adjusting for age,gender,tumor stage,symptoms,multivariate Cox regression showed that pre-operative high PTC was an independent prognostic factor associated with a decreased OS (HR =2.086,95 % CI 1.495-2.287,P =0.014) and decreased RFS (HR =2.234,95% CI 1.546-2.334,P =0.045).Conclusion The preoperative morning PTC is an independent risk factor for the prognosis of ACC.

ABSTRACT

Objective To investigate the relationship between placental endoglin expression and the pathogenesis of severe preeclampsia (SPE). Methods Forty nine pregnant women with SPE and 40 normal pregnant controls were collected in Peking University First Hospital from January 2006 to January 2008,among which,nine SPE patients complicated with fetal growth restriction (FGR),six with hemolysis,elevated liver enzymes and low platelets syndrome (HELLP syndrome) and 12 with heavy proteinuria. The expression of placental endoglin was detected and semi-quantified by immunohistochemistry.Data were analyzed by independent sample t test. Results Endoglin was presented on cell membranes of placental syncytiotrophoblasts and vascular endothelial cells. The endoglin density of SPE group was higher than that of control group (0.1621± 0.0029 vs 0.1576 ± 0.0038,t=- 6.367,P<0.05).No significant difference in endoglin density was found between FGR group and non-FGR group (0.1611±0.0026 vs 0.1623±0.0029,t=1.107,P>0.05) ; neither did the heavy proteinuria group and non-heavy proteinuria group (0.1611±0.0032 vs 0.1624±0.0027,t=1.350,P>0.05).The endoglin density of HELLP group was lower than that of non-HELLP group (0.1595±0.0032 vs 0.1625±0.0027,t=2.495,P=0.016). Conclusions The elevated placental endoglin expression might contribute to the pathogenesis of SPE.

Objective To investigate the efficacy and side effects of the molecular targeted drug sunitinib in the treatment of metastatic renal cell carcinoma(mRCC). Methods Fifteen patients with histopathological confirmed mRCC,including 10 males and 5 females,were enrolled in the study.The median age was 56(range from 37 to 73 years).Fourteen cases of clear-cell RCC and 1 papillary RCC were diagnosed.Thirteen patients had prior nephrectomy,and 6 patients were treated with cytokines previously.All of the patients were given sunitinib at a dosage of either 50 mg daily(4 weeks on/2 weeks off)or 37.5 mg daily continuously.Objective response rate(ORR),progressive-free survival(PFS)and overall survival(OS)were evaluated,and adverse events were also observed. Results The median follow-up was 13 months(2-24 months).According to RECIST,partial response could be evaluated in 8 patients and stable was found in another 5 patients.Only 2 patients were confirmed disease progression.The ORR was 53% with the disease control rate of 87%,However,the median PFS and OS were not yet available due to the short-term follow-up.During the treatment,the most common adverse events experienced by patients were hand-foot syndrome 11/15(73%),changes in hair color 10/15(67%),mucositis 9/15(60%),alopecie 9/15(60%),diarrhea 8/15(53%)and neutropenia 8/15 (53%). All of adverse events were manageable and reversible. Conclusions Sunitinib as a single agent in the treatment for Chinese mRCC patient is efficient and the side effects are reversible. Further long-term follow-up and expanded samples should be expected to confirm the efficacy and safety of sunitinib.

ABSTRACT

Objective To discuss the serum endoglin expression in severe pre-eclampsia and eclampsia women and their relationships. Methods Forty-two severe pre-eclamptic patients and 4 eclamptic patients in Peking University First Hospital from Dec. 2005 to Dec. 2007 were enrolled in the study group, with the mean gestational week of 35 ± 4, the mean age of 29.3 ± 5.7 and the mean BMI (30.1 ± 4.1 ) kg/ m2. This group included 25 cases of early onset pre-eclampsia, 21 cases of late onset pre-eclampsia, 8 cases of fetal growth restriction and 5 cases of HELLP syndrome. The control group included 29 cases of normal pregnant women during the same period, with the mean gestational week of 33±4, the mean age of 30.7± 3.4 and the mean BMI(27.2±2. 2) kg/m2. Peripheral serum endoglin was determined by ELISA in these two groups. Results (1)There is positive correlation between serum soluble endoglin level and the gestational weeks during 27 to 37 gestational weeks in the control group (r=0.79, P<0.05), but there is no distinct relationship in the study group (r=0.31, P>0.05). (2) Serum endoglin level of severe pre-eclampsia group was higher than the normal group [(14.2±5.6)μg/L vs. ( 10.9 ± 4.2 ) μg/L, P<0.05]. (3) Serum endoglin level of early onset group did not differ from late onset group [(14.3±5.7)μg/L vs. (13.6±5.0)μg/L, P >0.05]. (4) No difference of serum endoglin between HELLP group and non-HELLP group was found [(10.1±2.9) μg/L vs. ( 14.4±5.4) μg/L, P>0.05 ]. (5) Serum endoglin level of FGR sub group was higher than non-FGR sub group [(17.3±6.1) μg/L vs. (13.0±4.8) μg/L, P < 0.05] in the stady group. Conclusion The elevated peripheral serum endoglin level may contributes to the pathogenesis of severe pre-eclampsia and FGR, but not the week of the onset of the disease.

ABSTRACT

SUMMARY In recent years, successful pregnancies in renal transplant women have been reported worldwide. However, pregnancy in renal trasplant recipient is relatively rare in China. This paper reported a case of pregnancy 2 years post renal transplant. At the end of 28 weeks' gestation she had abnormal liver and renal function complicated with severe preeclampsia. Literatures were reviewed on considerations about pregnancy in renal transplant women. Maternal and neonatal outcomes can be improved by intensive care during pregnancy, proper immunosupression and timely termination of pregnancy.

ABSTRACT

Objective To observe the effect of topical application with warm and wet carthamus tinctorius alcohol and anisodaminum on phlebitis caused by mannitol injection. Methods 100 patients with fractured bones suffered from phlebitis caused by mannitol injection were randomized into the observation group and the control group with 50 cases in each group. The observation group adopted topical application with warm and wet carthamus tinctorius alcohol and anisodaminum while the control received external application of 50% magnesium sulfate. The dosage was 3 hours per time,2 times a day, one time in the morning and afternoon respectively. The treatment continued till the phlebitis disappeared and the effect at the 24th,48th and 72th post treatment was compared between the two groups. Results The effect at the above mentioned time points in the obsevation group was superior to that of the control group(P<0.05).Conclusion Topical application with warm and wet carthamus tinctorius alcohol and anisodaminum on phlebitis caused by mannitol injection proved to be safe and had no adverse effect.
