ABSTRACT
Objective:To investigate the effect of laparoscopic ovarian cystectomy on anti-Mullerian hormone (AMH) level, ovarian response to gonadotropin stimulation and pregnancy rate for in vitro fertilization (IVF) patients with benign ovarian cysts.Methods:Patients with benign ovarian cysts who were admitted for cystectomy and had undergone IVF treatment were enrolled in the study. There were 373 participants with ovarian cysts underwent laparoscopic ovarian cystectomy in the experimental group. According to duration of post-surgery, there were four sub-groups: 1 year post-surgery (1Y POST), 2 years post-surgery (2Y POST), 4 years post-surgery (4Y POST) and ≥5 years post-surgery (≥5Y POST) in the experimental group. According to histopathologic types of ovarian cysts, there were two sub-groups: ovarian endometriotic cysts and ovarian non-endometriotic cysts. Two hundreds and three patients with no history of ovarian cysts and ovarian surgery were in the control group. The level of AMH and basic concentrations of follicle stimulating hormone (FSH), luteinizing hormone (LH), progesterone (P), estradiol (E 2) were measured. Antral follicle counts (AFC) were calculated. There were other study variables: total dose of gonadotropins, duration of ovarian stimulation, the number of oocyte retrieved, the number of embryo obtained, blastocyst transfer rate and pregnancy rate. Results:The control group was matched as closely as possible to the experimental group, including age, body mass index and menstrual cycle (all P>0.05). Compared to the women in control group, the women in ovarian endometriotic cystectomy sub-group had significantly higher levels of basal FSH and basal P, lower level of AMH (all P<0.05); the women in ovarian endometriotic cysts sub-group had significantly higher dose of gonadotropins (all P<0.05); the women in ovarian endometriotic cysts ≥5Y POST sub-group had significantly lower number of oocyte retrieved, lower number of embryo obtained, lower blastocyst transfer rate, and lower pregnancy rate (all P<0.05). Compared to the women in control group, the women in ovarian non-endometriotic cysts sub-group had a significantly higher level of basal FSH and basal P (all P<0.05). The women in ovarian non-endometriotic cysts sub-group had lower level of AMH, higher dose of gonadotropins, lower number of oocyte retrieved, lower number of embryo obtained, lower rate of blastocyst transfer and lower rate of pregnancy than the control group but there were no statistically significant differences among them (all P>0.05). The women with unilateral ovarian endometriotic cysts had significantly lower number of oocyte retrieved on the side of surgery than another side ( P<0.05). Conclusions:In short term laparoscopic ovarian cystectomy has no significant effect on ovarian reserve. But with long-term follow-up ovarian reserve, ovarian response to gonadotropin stimulation and pregnancy rate are decreased. The effect of laparoscopic ovarian cystectomy in benign cysts on ovarian is associated with whether or not it is the surgical side.
ABSTRACT
Objective:To explore the clinical outcomes of top-quality blastocysts transfer developed from cleavage embryos with different grading and determine whether the cleavage stage embryo morphology grading should be taken into consideration when transferring the embryo at the blastocyst stage.Methods:A number of 3 059 cycles were included with single top-quality blastocyst transfer dating from January 2017 to May 2021 in Henan Provincial People′s Hospital. According to the number of cleavage sphere and degree of fragmentation, all cleavage stage embryos were divided into three groups: top D3 embryo (8 cells, ≤5% fragments)-TB group, suboptimal D3 embryo (8 cells, 5%<fragments≤10%; 7 cells or 9 cells, ≤10%)-TB group, and normal D3 embryo-TB group. Univariate analysis, multivariate logistic regression analysis and threshold effect analysis were performed on the data.Results:The clinical pregnancy rates of top D3 embryo-TB group(1 326 cycles), suboptimal D3 embryo-TB group (830 cycles) and normal D3 embryo-TB group (903 cycles) were 69.53%, 70.12% and 66.67%, respectively ( P>0.05); and the early abortion rate were 10.74%, 12.54% and 12.62%, respectively ( P>0.05). After adjusting for confounders, logistic regression showed that no significant associations were found between cleavage stage embryo morphology grading and clinical pregnancy rate (suboptimal D3 embryo-TB group: OR=1.02, 95% CI: 0.76-1.38, P=0.879; normal D3 embryo-TB group: OR=0.84, 95% CI: 0.61-1.14, P=0.262) and early abortion rate (suboptimal D3 embryo-TB group: OR=1.18, 95% CI: 0.77-1.82, P=0.445; normal D3 embryo-TB group: OR=1.26, 95% CI: 0.81-1.98, P=0.309). The results of threshold effect analysis showed that when a single top-quality blastocysts was transferred, the effect of age on the clinical pregnancy rate showed a curve relationship, when the age was≥33 years old, the clinical pregnancy rate decreased significantly with age increased ( OR=0.89, 95% CI: 0.83-0.95, P=0.007); and there was no significant change in early abortion rate ( OR=1.01, 95% CI: 0.97-1.06, P=0.628). Conclusions:Cleavage stage embryo grading is not found to correlate with clinical outcomes in single top-quality blastcyst tranfer. Therefore, when considering blastocyst transfer, its morphology at blastocyst stage is more relevant. The effect of age on pregnancy outcomes of single blastocyst transfer should be considered.
ABSTRACT
Objective:To explore the effectiveness, safety and cost between urinary follicle stimulating hormone (uFSH) and recombinant follicle stimulating hormone (rFSH) in controlled ovarian stimulation (COS) in China.Methods:Data were collected from 16 reproductive centers in China covering oocytes collection time from May 1, 2015 to June 30, 2018. Eligible patients were over 18 years old, adopting COS with uFSH (uFSH group) or rFSH (rFSH group) as start gonadotropins (Gn), and using in vitro fertilization (IVF) and (or) intracytoplasmic sperm injection for fertilisation, excluding frozen embryo recovery cycle. Generalised estimating equation was used to address the violation of independency assumption between cycles due to multiple IVF cycles for one person and clustering nature of cycles carried out within one center. Controlling variables included age, body mass index, anti-Müllerian hormone level, cause of infertility, ovulation protocol, type of fertilisation, number of embryos transferred, number of days of Gn use.Results:Totally 102 061 cycles met eligibility criteria and were included in the analyses. In terms of effectiveness, after controlling relevant unbalanced baseline characteristics, compared with rFSH group, the high oocyte retrieval (>15 oocytes was considered high retrieval) rate of uFSH group significantly decreased in gonadotropin-releasing hormone agonist protocol ( OR=0.642, P<0.01) and in gonadotropin-releasing hormone antagonist protocol ( OR=0.556, P=0.001), but the clinical pregnancy rate per transfer cycle and the live birth rate per transfer cycle significantly increased ( OR=1.179, OR=1.169, both P<0.01) in both agonist and antagonist protocols. For safety, multiple analysis result demonstrated that in the agonist protocol, compared with rFSH group, the incidence of moderate to severe ovarian hyperstimulation syndrome of uFSH group significantly decreased ( OR=0.644, P=0.002). The differences in ectopic pregnancy rate and multiple pregnancy rate between the uFSH and rFSH groups were not significant ( P=0.890, P=0.470) in all patients. In terms of cost, compared with rFSH group, the uFSH group had lower total Gn costs for each patient ( P<0.01). Conclusion:For patients who underwent COS, uFSH has better safety, and economic profiles over rFSH in China.
ABSTRACT
Objective:To explore the related factors of poor ovarian response (POR) in patients receiving controlled ovarian stimulation (COS) and to establish the nomogram for predicting POR in patients who received in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI).Methods:In this retrospective research, clinical data of 17 164 cycles of patients who received IVF/ICSI treatment at Henan Provincial People′s Hospital from September 1st, 2016 to September 1st, 2020 were analyzed. Independent correlative factors affecting the occurrence of POR were screened by logistic regression, which were the model enrollment variables in the prediction model. Totally 13 266 cycles with well-record of enrollment variables were screened, and these data were randomly divided into model group (9 896 patients) and validation group (3 370 patients) according to 3∶1. The nomogram was established according to the regression coefficient of the relevant variables. The prediction accuracy of the nomogram was evaluated by calculating area under the receiver operating characteristic curve (AUC).Results:Multivariate logistic regression analysis showed age, infertility type, body mass index, anti-Müllerian hormone, basal follicle stimulating hormone, basal estrogen, antral follicle number, previous times of POR, history of ovarian surgery, ovulation stimulation protocol and average amount of gonadotropin were independent correlative factors affecting the occurrence of POR (all P<0.05). In the model group, according to the above factors, the prediction model and nomogram of POR risk were constructed and the validation group verified the model. The AUC of the model group was 0.893 (95% CI: 0.885-0.900), and the AUC of the validation group was 0.890 (95% CI: 0.878-0.903). Conclusion:The influencing factors of POR after COS in patients treated by IVF/ICSI are screened, and the nomogram for predicting POR established in this study is proved to be effective, simple, intuitive and clear in predicting the occurrence of POR.
ABSTRACT
@#OBJECTIVE To investigate the situation of pharmaceutical pr eparations in medical institutions （hereinafter refer to hospital preparations ），and to promote the sustained and healthy development of hospital preparations. METHODS Under the organization of National Pharmacy Administration & Quality Control Center ，internet survey was adopted to statistically analyze the data of hospital preparations in 2019 that was completed and reported by the secondary general hospitals and above in provinces （cities，districts）and Xinjiang Production and Construction Corps. RESULTS Among the 4 639 hospitals，9.36％ had drug approval numbers and 8.15％ had preparation laboratories. The average ratio of the number of hospital preparations in production to the number of preparations approved was 0.72，and that of 41.52％ hospital was concentrated in 1-0.9. Self-produced by hospital was the main production mode of hospital preparations ；the higher hospital level was ，the higher the proportion of self-production combined with commissioned processing ，while the lower the proportion of commissioned processing only. In hospitals with preparation approval numbers ，the proportion of owning TCM preparations was the highest （73.66％），followed by common chemical preparations （69.93％）. From perspective of annual output value of hospital preparations ，tertiary hospitals were higher than secondary hospitals ，and private hospitals were higher than public hospitals ；it was related to the production mode ，varieties of hospital preparations and the establishment of the preparation laboratories. There was a trend that the development of hospital preparations in C entral China ，North China and South China was better than that in the Northeast China ，Northwest China and Southwest China. CONCLUSIONS At present ，hospital preparations in China are mainly made in medical institutions ， com and the types are relatively limited. The regional developmentis unbalanced and the scale of hospital preparations is reduced.It is suggested that medical institutions should pay attention to the innovation of hospital preparations ，especially to deve lopment of characteristic preparations with definite curative effect ，so as to give full play to their role of “shortage make-up ”. Great importance also should be paid to the policy support of dispensing and the establishment of regional dispensing centers.
ABSTRACT
Objective:To assess the nutritional status of elderly patients with dementia in a memory clinic and to identify patients with malnutrition and patients at risk for malnutrition.Methods:A total of 510 elderly dementia patients were recruited from a memory clinic of the First Affiliated Hospital of Chongqing Medical University.All subjects were assessed with the mini-nutritional assessment short-form(MNA-SF), mini-mental state examination(MMSE), activities of daily living scale(ADL)and neuropsychiatric inventory(NPI). Logistic regression was used to explore potential risk factors and to establish a prediction model.Results:13.33%(68/510)of participants were classified as being malnourished, 52.94%(270/510)as being at risk for malnutrition and 33.73%(172/510)as well nourished.A Logistic regression model for predicting malnutrition identified dysphagia, irritability, physical self-maintenance scale(PSMS), appetite and eating disorders as important influencing factors( OR=4.334, 1.096, 1.121, 1.213, all P<0.05), and MMSE score, family history of dementia and age were important influencing factors for predicting malnutrition/at risk for malnutrition( OR=0.923, 0.517, 1.045, all P<0.05). Conclusions:The incidence of malnutrition and the risk of malnutrition in elderly patients with dementia in the memory clinic are high, and there are many related influencing factors.Early detection and intervention can delay or avoid malnutrition.
ABSTRACT
OBJECTIVE@#To explore the clinical feature and gene variant for two cases of primary male infertility caused by severe asthenospermia and to analyze the etiology of the disease.@*METHODS@#Genomic DNA of peripheral blood samples of patients and their parents was extracted and gene variant analysis of the patients was conducted by using whole exome sequencing. Suspected pathogenic variant was verified by Sanger sequencing and pathogenic analysis.@*RESULTS@#Whole exome sequencing showed that the DNAH1 gene of patient 1 had two heterozygous variants of c.2016T>G(p.Y672X) and c.6017T>G (p.V2006G). The DNAH1 gene of patient 2 had a homozygous variant of c.2610G>A(p.W870X), which were inherited from his father and mother, respectively.

Objective:To investigate the effect of endometrial thickness(EMT) on the clinical outcome of blastocyst hormone replacement freeze-thawed embryo transfer (HRT-FET) on the first progesterone day, and to analyze the threshold and optimal thickness interval corresponding to ideal clinical pregnancy rate by statistical method.Methods:The endometrial preparation protocols of 2 825 blastocyst HRT-FET cycles from January 2013 to December 2016 in Henan Provincial People′s Hospital and the Second Hospital of Hebei Medical University were studied retrospectively. According to EMT on the first progesterone day, they were divided into 5 subgroups: group Q1(EMT: 3.5-7.9 mm), group Q2(EMT: 8.0-8.9 mm), group Q3(EMT: 9.0-9.5 mm), group Q4(EMT: 9.6-10.7 mm), group Q5(EMT: 10.8-21.0 mm). Univariate analysis, classification multivariate Logistic regression analysis, curve fitting and threshold effect analysis were used to investigate the effect of endometrial thickness on clinical outcome of blastocyst HRT-FET.Results:Group Q1 was set as the control group in classification multivariate Logistic regression analysis, after adjusting for confounding factors, the clinical pregnancy rate and live birth rate in other groups were higher than the control group. The clinical pregnancy rate and live birth rate in group Q3 and Q4 were significantly increased and the differences were statistically significant(all P<0.05). The cut-off value of the endometrial thickness was 9.6 mm. When endometrial thickness was less than 9.6 mm, with 1 mm increase of endometrial thickness, the clinical pregnancy rate increased by 23%( OR=1.23, 95% CI=1.11-1.36) and the live birth rate increased by 21%( OR=1.21, 95% CI=1.10-1.33). When the endometrial thickness was thicker than the threshold, the clinical pregnancy rate did not increase significantly( OR=0.92, 95% CI=0.84-1.02), and the live birth rate showed a downward trend( OR=0.88, 95% CI=0.81-0.96). Conclusions:In the blastocyst HRT-FET cycle, endometrial thickness showes a curvilinear relationship with clinical outcome. The optimal endometrial thickness range for ideal clinical outcome is 9.0-11.0 mm.
ABSTRACT
Objective To explore the value of anti-Müllerian hormone (AMH) and age in predicting outcomes of patients undergoing in vitro fertilization and embryo transfer treatment. Methods In this retrospective study, 6 328 Chinese patients who underwent the first in vitro fertilization or intracytoplasmic sperm injection and embryo transfer treatment in Henan Provincial People′s Hospital between July 2016 and July 2018 were analyzed. All the patients were categorized into two groups according to pregnancy or not. Baseline data and outcomes of two groups were compared. The regression analysis was conducted to identify the independent factors of clinical pregnancy rates. Furthermore, correlation analysis was performed between AMH and other factors. Results (1) The total clinical pregnancy rate was 56.86% (3 547/6 238). Age, AMH, basal FSH, antral follicle number (AFC), starting dose of gonadotropin (Gn), total doses of Gn, duration of Gn, number of oocytes, transferable cleavage embryos and transferred embryos were significantly different (all P<0.01). (2) Correlation analysis showed that AMH had significant passive correlation with age, basal FSH, starting dose of Gn and total doses of Gn (all P<0.01), while showed significant positive correlation with AFC, body mass index, duration of Gn, number of oocytes and transferable cleavage embryos (all P<0.01). Of all the factors, AMH had the strongest correlation with AFC (P<0.01). (3) Multivariate logistic regression analysis suggested that age was the independent influencing factor of clinical pregnancy rate ( OR=0.938, 95%CI : 0.824-0.952, P<0.01), while AMH not ( OR=1.004, 95%CI : 0.984-1.024, P=0.687). In the subgroups according to age, the advanced group (age>35 years old) had lower clinical pregnancy rate and higher cancellation rate for no available embryos. Conclusions AMH has no predictive value of clinical pregnancy outcomes for patients with in vitro fertilization and embryo transfer treatment, while age has certain predictive value of pregnancy outcomes. AMH level may have indictive value for the evaluation of ovarian reserve.
ABSTRACT
Objective: To predict the optimal single-batch production and annual production batches for five oral solutions in order to support equipment upgrade and control reasonable cost as well as provide reference for optimizing production management of new preparation room. Methods: The clinical use of the five oral solutions in four consecutive validity periods was retrospectively analyzed. Decision analysis was used to predict the optimal single-batch production and annual production batches for the five oral solutions. The weight coefficient was adjusted according to the clinical characteristics of each preparation. Results: The optimal single-batch produc-tion for the five oral solutions was five to seven times larger than the current scale while the annual production batches were greatly re-duced. In particular, compound ammonium chloride and glycyrrhiza oral solution ( formerly known as brown mixture) were reduced from 95 batches to 13 batches per year. Conclusion: The optimal prediction can provide reference for the appropriate adjustment of production scale of hospital preparations to lower the cost of single packaging production. At the same time, it is also beneficial to the overall management of production equipment selection and future scale design for new preparation room.
ABSTRACT
Objective To establish a mouse model of intrauterine malnutrition to investigate the growth characters and the DNA methylation level of H19 of the offspring. Methods The pregnancy ICR mice were randomly divided into the food restricted group and the control group. The food eaten by each pregnant mouse every day was monitored from d0. 5 to d12. 5. The food restricted pregnancy mice were given half amount food of the daily consumption during d0. 5-d12. 5. The mice in control group were given the normal food. The pregnant mice of both groups of were given normal food after delivery. The number, birth weight and sex ratio of the offspring were calculated. Furthermore, the body weight of the offspring was monitored at different growth stages. The oocytes of female offspring mice were obtained to detect the DNA methylation level of H19. Results (1) Compared to normal feeding pregnant mice, mice with food restricted were small and less active, and even some of them were died before delivery. The incidence of premature birth was significantly increased (P ＜0. 05). The number of abortion, stillbirth pregnant mice in the food restriction group were more than that in the control group, but the difference was not statistically significant (P ＞ 0. 05). (2) There was no significant difference in the number of offspring between pregnancy mice with food restricted or normal food (P ＞ 0. 05). As well as the number of male offspring between the two groups (P ＞ 0. 05). However, the offspring of the food restricted pregnant mice showed significant low birth weight (P ＜ 0. 05). (3) At the age of 3 weeks, there was still a low body weight in the offspring of the food restricted pregnant mice, but the difference had no significant difference between groups (P ＞ 0. 05). After weaning at 3 weeks, the offspring of food restricted pregnant mice began the catch-up growth. At the age of 6 weeks, the body weight of offspring of food restricted pregnant mice was higher than that of the normal offspring, but the difference was not statistically significant (P ＞ 0. 05). During the period of 6-8 weeks, the weight of offspring of normal feed pregnancy mice was increased slowly. But the body weight of food restriction offspring mice was increased rapidly. At the age of 8 weeks, the body weight of offspring of food restricted group was significantly higher than that in control group (P ＜ 0. 05). (4) The methylation level of H19 in oocyte from offspring of food restricted pregnancy mice was normal. Conclusion Food restriction at pregnancy period not only affect the outcome of pregnancy, but also increased the rate of premature birth. The offspring of food restriction pregnancy mice showed low birth weight. Until the age of 6 weeks, the offspring of food restriction pregnancy mice had lower body weight compared with the offspring with normal feeding pregnancy mice. The offspring of food restriction pregnancy mice demonstrated obesity at 8 weeks. But the H19 methylation levels of oocytes from offspring of pregnancy mice with food restriction was normal.

ObjectiveTo evaluate the predictive value of the sperm quality to fertilization outcomes after short-time insemination.MethodsA total of 558 cycles of short-time insemination in the Reproductive Medical Center of Henan Provincial People's Hospital during January 2009 to June 2010 excluding patients aged ＞ 38 years and M Ⅱ oocyte number ＜ 3 were analyzed retrospectively.According to whether undergo rescue intracytoplasmic sperm injection( Re-ICSI),all cycles were divided into in vitro fertilization (IVF)group (472 cycles) and rescue intracytoplasmic sperm injection (Re-ICSI) group (86 cycles).Both IVFgroup and Re-ICSI group were subdivided into primary infertility and secondary infertility according to previous history of pregnancy.269 primary infertility cycles and 203 secondary infertility cycles were characterized in IVF group; and 64 primary infertility cycles and 22 secondary infertility cycles were characterized in Re-ICSI group.x2 test was applied for comparison of embryo plant rate,clinical pregnancy rate,early miscarriage rate between IVF and Re-ICSI groups,while Fisher test was used for comparison of live birth rate.and Mann-Whitney U test was utilized for comparison of duration of infertility,forward moving sperm counts,abnormal sperm rate,sperm acrosin activity between IVF and Re-ICSI groups.ResultsThe embryo plant rate,clinical pregnancy rate,early miscarriage rate,live birth rate of IVF group were:29.4％,44.9％,13.4％,37.0％ respectively; the above indicators in Re-ICSI group were:25.7％,34.6％,10.7％,29.6％ respectively,the differences of the indicators between the two groups had no statisticalsigmficance (x2 =0.869,2.963,0.010,P =0.351,0.085,0.922,0.098).Median of duration of infertility,forward moving sperm counts,abnormal sperm rate,sperm acrosin activity of primary infertility cycles in IVF group were:4.00(3.00 -6.00) years,58.37(33.64 - 102.27) × 106,81.09％ (79.41％ -88.69％ ),76.30 (48.50 - 92.46 ) μIU/106 sperm respectively ; in Re-ICSI group were:5.00 ( 3.25 -8.00) years,36.33 (20.59 -64.43 ) × 106,85.5％ (81.28％ - 89.02％ ),47.14( 31.61 -90.24) μIU/106 sperm respectively,the differences of them between the two groups had statistical significance (Z =-2.617, -3.505, -3.553, -3.530,P =0.009,0.000,0.000,0.000).Median of duration of infertility,forward moving sperm counts,abnormal sperm rate,sperm acrosin activity of secondary infertility cycles in IVF group were:5.00 (3.00 -7.00) years,63.00 (34.20 - 107.73 ) × 106,81.29％ (79.90 -86.09) ％,78.34 ( 53.87 - 98.00) μIU/106 sperm respectively,in Re-ICSI group were:5.00 ( 3.75 -7.00) years,28.80 ( 18.57 - 48.56 ) × 106,88.79％ ( 84.04 - 95.64 ) ％,54.70 ( 39.73 - 76.77 ) μIU/106 sperm respectively,the differences of them between the two groups showed statistical significance except duration of infertility (Z =- 0.338,- 3.505,- 3.553,- 3.530,P =0.735,0.000,0.000,0.006).ConclusionThe duration of infertility,forward moving sperm counts,abnormal sperm rate,sperm acrosin activity have predictive value of fertilization outcomes after short-time insemination.
ABSTRACT
Objective To study ovarian development in vitrificatiou of embryos born mice and expression of growth differentiation factor 9 ( GDF-9 ) in its.MethodsThe vitrification recovery embryos (vitrified-embryo group) and fresh embryos (fresh-embryo group) were transplanted into pseudopregnant mice,respectively.The female offspring mice in two groups were sacrificcd on the 3rd,7th,14th,21st,28th and 60th day after birth,the ovarian tissues were taken,6 mice in each time point of each group.The ovarian development was observed by HE staining,the expression of GDF-9 mRNA and protein at each time point of two groups were detected by reverse transcription(RT)-PCR and western blot.ResultsHE staining showed that no abnormal ovarian development was observed in offsprings at two groups.On the 3rd,7th,14th,21st,28th and 60th day after birth,the expression of GDF-9 mRNA in vitrified-embryo group were 0.14 ± 0.07,0.42±0.16,1.00±0.24,1.59±0.28,2.05 ±0.32 and 2.23 ±0.21,respectively,which in fresh-embryo group were 0.13 ±0.06,0.45 ±0.18,1.00 ±0.21,1.56 ±0.26,2.01 0.37 and 2.26 ±0.23,respectively,there was no statistical difference between two groups ( P ＞ 0.05 ) ; the expression of GDF-9 protein in vitrified-embryo group were 0.040 ± 0.030,0.120 ± 0.060,0.170 ± 0.030,0.250 ± 0.040,0.320± 0.060 and 0.330 ± 0.010,respectively,which in fresh-embryo group were 0.030 ± 0.020,0.110 ± 0.040,0.150 ± 0.010,0.210 ± 0.020,0.360 ± 0.070 and 0.350 ± 0.030,respectively,there was no statistical difference between two groups ( P ＞ 0.05 ).Conclusion The ovarian morphology in vitrification of embryos born mice and expression of GDF-9 in ovary has no any obvious change.
ABSTRACT
Objective To investigate the clinical and pathological features of small cell carcinoma of the urinary bladder. Methods The pathological and clinical data of 9 cases of small cell carcinoma were analyzed retrospectively. There were 6 males and 3 females, ages 45 to 79 years (mean age, 62 years). Clinical manifestations of 7 cases included gross hematuria and dysuria, the other 2 cases experienced lower abdominal pain. The mean tumor size was 2.0 cm (ranged, 0.5 to 7.0 cm). Two cases had multiple tumors and 5 cases had single tumors. The growth pattern in 2 cases was diffuse growth in the whole bladder. In 4 cases tumor cells were found in urine cytology. All 9 patients underwent surgical treatment, including TURBt. Four patients were diagnosed as superficial tumors before operation. All the patients underwent regular theprubicine irrigation in the bladder. One case underwent additional intravenous chemotherapy for 3 cycles. Partial cystectomy was performed in 2 cases, with regular theprubicine irrigation in bladder and 1 case underwent intravenous chemotherapy for 2 cycles. Radical cystectomy was performed in 3 cases, with 2 cases undergoing intravenous chemotherapy after operation. Results Pathological findings showed that tumor cells were small and round in shape. These hyperchromatic nuclei showed limited cytoplasm with lack of nesting characters. CgA and NSE were positive in immunohistochemistry. The final diagnosis was small cell carcinoma, with 1 case accompanied with transitional cell carcinoma and 1 case accompanied with prostate cancer. One case showed high preoperative serum calcium (3.15 mmol/L) and low serum phosphate (0.61 mmol/L), which returned to normal 1 month after operation. Four cases who′s bladder was preserved were followed up, 3 cases were alive for 4, 9 and 25 months after operation. The 1 case who underwent intravenous chemotherapy was followed up for 24 months and there was no sign of relapse or metastasis. In all the 3 cases with radical cystectomy, 2 cases died 2 and 28 months postoperativly. Another case with adjuvant chemotherapy was followed up for 24 months without recurrence or metastasis. Conclusions Small cell carcinoma of the urinary bladder is highly malignant with poor prognosis. Radical cystectomy in combination with systemic chemotherapy has better efficacy. Retained bladder surgery with systemic chemotherapy is an alternative choice. The most important factors which influence the prognosis of the tumor are clinical stage and therapeutic methods.
ABSTRACT
Objectlve To discuss the characters and management of renal sinus tumors. Methods The clinical data of 3 tumors occurring in tenal sinus were reviewed.The first patient was a 33-year-old man with the chief complaint of lumbago in the right side for 6 months.B-ultrasound showed low echo in the right pelvis and CT scan showed that a mass measured about 3.5 cm in diameter in the right kidney collective system.Intravenous urography showed the upper collective system was tompressed.He was diagnosed for renal sinus tumor.The second case was a 34-year-old woman with the chief complaint of sudden lumbago in the right for 3 d.Color ultrasonography found hyperechoic in the right kidney.CT scan showed a mass measured 8 cm×6 cm × 8 cm in the right renal sinus,its CT value was about-70 HU.Intravenous urography showed the lower collective system was compressed.She was diagnosed for renal angiomyolipoma of right kidney.The third case was a 55+year-old woman with the chief complaint of lumbago for 1 year.B ultrasound showed hyperechoic in the leftrenal hilum.CT scan showed a nlass of 8 cm×5 cm×5 am in the left renal sinus with CT value of 50 HU.Intravenous urography showed the collective system of the left kidney was compressed.Mag-netic resonance imaging showed high signal on T1 WI and T2WI but low signal in fat suppression ima-ging.She was diagnosed for lipoma of the left renal sinus. Results All the 3 cases had undergone surgical approaches.The first case underwent surgical exploration of renal sinus tumor.Fast pathologic diagnosis was benign tumor,only the tumor was resected.Postoperative pathology confirmed the diagnosis of angioleiomyoma.There was no recurrence during follow-up of 3 years.The second case was scheduled for tumor enucleating,but nephrectomy was perform because of serious bleeding and damaged renal pelvis.Pathological report was angiomyolipoma.The third case was scheduled for lipoma enucleating but nephrectomy was performed because of tumor encapsulated renal pedicle vascular.Pathological report was lipoma.During the follow-up for 4 years there was no relapse. ConclusionsTumors occurred in renal sinus are rare, most of which are benign.CT scan, MRI and intravenous urography are the best imaging examination methods for differential diagnosis.Surgical operation is the major approach, while for the tumor radical nephrectomy less than 4 cm watchful waiting could be a choice.Tumor resection with nephron sparing is feasible while tumor is larger than 4 cm.Radical nephrectomy should performed for the malignant tumor.
ABSTRACT
Objective To discuss the surgical management of von Hippel Lindau(VHL) syn drome.Methods The clinical data of four VHL patients who were clinically diagnosed from March1999 to October 2006 were reviewed.The first patient was a 56 year old man with the chief complaintof hypodynamia and low serum glucose as 2.37 mmol/L.CT scan showed three masses in the the leftkidney.He had a history of cerebral haemangioblastoma ten years before.The second case was a 57 year old woman with the chief complaint of lumbago in the left side.CT scan showed masses in theleft kidney,adrenal gland and panerease.The third case was a 39 year old woman with the chief com plaint of an accident mass in the left adrenal gland.She had the history of cerebellar hemangioblastoma9 years before,spinal hemangioblastoma resection 7 years before.The fourth case was a 41-year oldwoman,she was found brain tumors and cured by gamma radiation abalation.Bilateral renal masseswere found by B ultrasound one month later,CT scan showed four masses in the both kidneys,leftadrenal gland and pancreas.Results All 4 cases underwent surgical approach.The first case under went radical nephrectomy which pathological report was PEComa of kidney.The blood glucose wasnormal one week later.The second case underwent resection of the left adrenal gland,kidney,pancre atic body and tail and spleen.Pathological report was clear cell carcinoma,islet cell tumor and adrenal cyst.Three months later she was found spinal hemangioblastoma and refused treatment.The thirdcase underwent adrenalectomy in the left side and pathologieal report was adrenal pheoehromocytoma.There was not tumor reeurrenee during 2 years' follow up.The nephrectomy and adrenalectomy wasperformed for the last ease whose pathological report was clear celt carcinoma and pheochromoeytoma.Three weeks later,tumor enueleating of the right kidney was undertaken; the result was clear cellcancer.During the follow up for one year there was no relapse of tumor.Conclusions For VHL ac companied with multiple organ tumors,surgery resection is the proper approaeh when tumors of centralnervous system is large.Different approaches could be taken to deal with multiple tumors of VHL such aswatchful waiting,nephron sparing surgery.
