ABSTRACT

OBJECTIVE@#To observe the effects of electroacupuncture (EA) on reproductive outcomes in women with Shen (Kidndy) deficiency syndrome after in vitro fertilization-embryo transfer (IVF-ET), and explore the underlying molecular mechanism.@*METHODS@#Sixty-six infertile patients with Shen deficiency syndrome undergoing IVF-ET were divided into EA or control groups according to a random table, 33 cases in each group. Before undergoing IVF, patients in the EA and control groups received EA therapy and placebo needle puncture, respectively, for 3 menstrual cycles. Shen deficiency syndrome scores were assessed. Other outcome measures included the number of retrieved oocytes and fertilization, high-quality embryo and clinical pregnancy rates. Follicular fluid was collected on the day of oocyte retrieval, and granulosa cell expression of phosphatidylinositide 3-kinases (PI3K), serine-threonine kinase (Akt) and forkhead box O3 (Foxo3a) mRNA were measured by reverse transcribed and quantitative real-time polymerase chain reaction.@*RESULTS@#Syndrome scores for pre- versus post-treatments decreased significantly (16.53±1.75 to 8.67±1.61) in the EA group (P<0.05), but showed no significant change in the control group (17.18±1.58 to 14.74±1.58). A significant difference in score change was found between the EA and control groups (P<0.05). High-quality embryo and clinical pregnancy rates were both increased in the EA group compared with the control group [69.15% (195/282) vs. 60.27% (176/292) and 66.67% (22/33) vs. 42.42% (14/33), respectively, P<0.05]. The fertilization rate was equivalent in EA and control groups. No difference was found in the number of retrieved oocytes between the two groups. Granulosa cell expression levels of PI3K and Akt mRNA were significantly increased in the EA group compared with the control group, while the expression of Foxo3a was reduced (all P<0.05).@*CONCLUSIONS@#For infertile patients with Shen deficiency syndrome undergoing IVF, EA for tonifying Shen as an adjunct treatment may alleviate clinical symptoms and improve the high-quality embryo rate. The EA-induced mechanism may involve regulation of PI3K/Akt/Foxo3a expression in granulosa cells to improve the developmental microenvironment of oocytes and inhibit granulosa cell apoptosis, possibly contributing to the improved clinical pregnancy rate (Registration No. ChiCTR 1800016217).

ABSTRACT

Disorders of sex development (DSD) is defined as a congenital condition or atypical development of the chromosomal, gonadal, or anatomic sex. The diagnosis, gender assignment, and treatment of DSD require the guidance from experienced multidisciplinary teams. So far there has been no consensus about it in China. Due to dysgenetic gonads, defects in sex steroid biosynthesis or action, or gonadectomy during the prepubertal years, those with DSD suffer from hypogonadism. The hormone replacement therapy of DSD aims at general physiological health and long-term prognosis as well as the avoidance of unnecessary genital and gonadal surgery. This review focuses on the advances in the studies of the diagnosis and hormone replacement therapy of 46,XY DSD.

ABSTRACT

Objective: Study on the influence of ζ potential on flocculating rate of Chinese herbs water-extract liquid. Methods: Chitosan of natural macromolecule flocculant was adopted to remove the flocculation impurity of the herb licorice (Glycyrrhizae Radix) extract, and the deep connection between ζ potential and liquid flocculating rate was proved by single factor experiment, orthogonal experiment, and granularity. Results: Under the influence of single factor conditions, absolute value of ζ potential of the system is lower, while the flocculation rate is higher. Based on orthogonal experiment, the optimum process condition of flocculating licorice extract is determined to be the flocculant dosage quantity of 0.347 g/L, pH value of 6, temperature of 30℃, and the system ζ potential of -1.67 mV, which is close to the isoelectric point among all the experiment. Whereas the flocculating rate was as high as 95.29%. The ζ potential of solution before flocculation is -14.78 mV, the average particle size is 17.12 μm; After the flocculation the ζ potential of clear liquid is -1.67 mV, the average particle size is 6.77 μm. The change of ζ potential affected the particle behavior of sol system and ultimately affected the liquid flocculating rate. Conclusion: In the process of flocculating herb licorice extract, the ζ potential has the important influence on the flocculation of herb extract. Absolute value of ζ potential of the system is lower, closer to the isoelectric point, the flocculation rate is higher. The ζ potential that reflects the flocculation essence provides a strong justification for the selection of flocculation conditions.

ABSTRACT

<p><b>INTRODUCTION</b>An increasing number of targeted drugs have been tested for the treatment of nasopharyngeal carcinoma (NPC). However, targeted therapy-related oncogenic mutations have not been fully evaluated. This study aimed to detect targeted therapy-related oncogenic mutations in NPC and to determine which targeted therapy might be potentially effective in treating NPC.</p><p><b>METHODS</b>By using the SNaPshot assay, a rapid detection method, 19 mutation hotspots in 6 targeted therapy-related oncogenes were examined in 70 NPC patients. The associations between oncogenic mutations and clinicopathologic factors were analyzed.</p><p><b>RESULTS</b>Among 70 patients, 12 (17.1%) had mutations in 5 oncogenes: 7 (10.0%) had v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog (KIT) mutation, 2 (2.8%) had epidermal growth factor receptor (EGFR) mutation, 1 (1.4%) had phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA) mutation, 1 (1.4%) had Kirsten rat sarcoma viral oncogene homolog (KRAS) mutation, and 1 (1.4%) had simultaneous EGFR and v-Raf murine sarcoma viral oncogene homolog B1 (BRAF) mutations. No significant differences were observed between oncogenic mutations and clinicopathologic characteristics. Additionally, these oncogenic mutations were not associated with tumor recurrence and metastasis.</p><p><b>CONCLUSIONS</b>Oncogenic mutations are present in NPC patients. The efficacy of targeted drugs on patients with the related oncogenic mutations requires further validation.</p>

ABSTRACT

Both platinum-based doublet chemotherapy (PBC) and epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) prolong the survival of patients with advanced non-small cell lung cancer (NSCLC). In early studies, most patients underwent PBC as first-line treatment, but not all patients could afford EGFR-TKIs as second-line treatment. To understand the impact of PBC and EGFR-TKIs on NSCLC prognosis, we evaluated the association between the receipt of both regimens and overall survival (OS). Using MEDLINE and EMBASE, we identified prospective, randomized, controlled phase III clinical trials in advanced NSCLC that met the inclusion criteria: in general population with advanced NSCLC, the percentage of patients treated with both PBC and EGFR-TKIs was available in the trial and OS was reported. After collecting data from the selected trials, we correlated the percentage of patients treated with both PBC and EGFR-TKIs with the reported OS, using a weighted analysis. Fifteen phase III clinical trials--involving 11,456 adult patients in 32 arms--were included in the analysis, including 6 trials in Asian populations and 9 in non-Asian (predominantly Caucasian) populations. The OS was positively correlated with the percentage of patients treated with both PBC and EGFR-TKIs (r = 0.797, P < 0.001). The correlation was obvious in the trials in Asian populations (r = 0.936, P < 0.001) but was not statistically significant in the trials in predominantly Caucasian populations (r = 0.116, P = 0.588). These results suggest that treatment with PBC and EGFR-TKIs may provide a survival benefit to patients with advanced NSCLC, highlighting the importance of having both modalities available for therapy.

ABSTRACT

<p><b>OBJECTIVE</b>To probe the effects of dexamethasone (DEX) combined with histone deacetylase (HDAC) inhibitor vorinostat on inhibiting proliferation and inducing differentiation and apoptosis in Kasumi-1 leukemia cells, and its possible mechanisms in order to provide a theoretical basis for the treatment of AML1-ETO positive AML.</p><p><b>METHODS</b>The cell survival, differentiation and apoptosis rates were tested by MTT or flow cytometry analysis after Kasumi-1 cells were treated by DMSO, DEX (20 nmol/L), vorinostat (1 μmol/L) or DEX (20 nmol/L) in combination with vorinostat (1 μmol/L). WB and IP-WB were performed to detect AML1-ETO and its ubiquitination.</p><p><b>RESULTS</b>Treatment with the combination of DEX and vorinostat for 48 h led to statistically significant differences of inhibited proliferation [(42.06±8.20)%], increased differentiation [(52.83±8.97)%] and apoptosis [(52.92±2.53)%] of Kasumi-1 cells when compared with vorinostat [(33.82±9.41)%, (43.93±9.04)% and (42.98±3.01)%, respectively], DEX [(17.30±3.49)%, (22.53±4.51)% and (19.57±2.17)%, respectively] or control [(6.96±0.39)%, (21.73±2.03)% and (6.96±0.39)%, respectively]. Also significant ubiquitination and decreased AML1-ETO protein in Kasumi-1 cells after the combination treatment over single agent or control were observed.</p><p><b>CONCLUSION</b>The results indicated that DEX and vorinostat could synergistically inhibit the Kasumi-1 cells proliferation, induce Kasumi-1 cells differentiation and apoptosis through ubiquitination and degradation of AML1-ETO.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate retrospectively the relationship between clinicopathological factors and lymph node matastasis of pancreatic adenocarcinoma.</p><p><b>METHODS</b>The clinicopathological factors, including gender, age, preoperative CA-19-9 level etc. of 71 patients with pancreatic adenocarcinoma were summarized to analyze the relationship between those factors and lymph node matastasis.</p><p><b>RESULTS</b>Among the 71 cases, there were 49 males (69.0%) and 22 females (31.0%). Forty-eight were ≥ 60 (67.6%) and 23 were < 60 (32.4%) years old. Twenty patients had normal preoperative CA-19-9 level (28.2%) and 51 had elevated level (71.8%). The tumor in 43 (60.6%) cases located in the pancreatic head and neck, and 28 (39.4%) in the body and tail. The tumors in 8 patients were well-differentiated (11.3%), 27 were moderately differentiated (38.0%), and 36 were poorly differentiated (50.7%). The maximum diameter of the tumor was ≤ 2 cm in 11 cases (15.5%), 2 - 5 cm in 45 cases (63.4%), and > 5 cm in 15 cases (21.1%). Ten patients had tumor confined to the pancreas (14.1%), and 61 invaded peripancreatic tissues (85.9%). Vascular tumor thrombus was found in 48 cases (67.6%), and 23 cases were absent (32.4%). Thirty-six cases had lymph node matastasis (50.7%). Univariate chi-square test revealed that differentiation and range of local infiltration were significantly associated with lymph node meatstasis (P < 0.05). Multivariate logistic regression analysis also showed that differentiation and range of local infiltration were significantly associated with lymph node meatstasis (P < 0.05).</p><p><b>CONCLUSIONS</b>The differentiation of tumor and range of local infiltration of pancreatic adenocarcinoma are significantly associated with lymph node metastasis. There is no significant relationship of location of the tumor, maximum diameter, presence or absence of vascular tumor thrombus with lymph node metastasis. Therefore, special attention should be paid to lymph node dissection in cases with a poorly differentiated pancreatic adenocarcinoma invading into peripancreatic tissues.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the clinical data and prognosis of gastric small cell carcinoma (GSCC), summarize recent progress in diagnosis and therapy of this disease reported in the literature, and to provide the theoretical basis for its appropriate treatment.</p><p><b>METHODS</b>Clinicopathological data of 17 patients with pathologically confirmed GSCC, treated in our hospital between 1999 to 2012, were retrospectively reviewed.</p><p><b>RESULTS</b>There were 16 males and 1 female, ranged from 46 to 75 years (mean 64.6 years). The tumor was located in the gastric cardia in 13 cases, three in the gastric fundus, and one in the gastric body. All the 17 patients received surgery and 10 of them received postoperative adjuvant chemotherapy, one received preoperative adjuvant chemotherapy. Thirteen patients were followed up. Among them, two 1ived for 40 months all along, the other 3 cases died of recurrence and extensive metastasis in 6 month after operation. The median survival was 13.0 months. The median survival of the patients with and without lymph node metastasis were 42 months and 13 months, respectively. The median survival time of stage II and III patients were 24 months and 14 months, respectively.</p><p><b>CONCLUSIONS</b>It is difficult to make a definite diagnosis before or during the operation for GSCC. Radical operation could be done according to other gastric cancers and lymph node dissection could be simplified. Postoperative chemotherapy with the same scheme as lung small cell carcinoma may help to improve the outcome and prolong the survival of the patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To assess the effects of acupuncture combined Chinese materia medica for tonifying shen and soothing gan (CMMTSSG) on the anxiety and depression of patients with in vitro fertilization and embryo transplantation (IVF-ET), and to observe the treatment outcomes.</p><p><b>METHODS</b>Totally 97 IVF-ET patients were randomly assigned to two groups, the acupuncture combined CMMTSSG (group A, 51 cases) and the Western medicine treatment group (group B, 46 cases). The long protocol of IVF-ET in a mid luteal phase was performed in all patients. Patients in group A received acupuncture and CMMTSSG (erzhi tiangui granule and xiaoyao granule) during the process of ovarian hyperstimulation, while those in group B only received the routines of IVF-ET. The improvement of Shen deficiency Gan depression syndrome (SDGDS) between after and before treatment were observed in the two groups. The changes of self-rating anxiety scale (SAS) and Beck depression inventory (BDI) score were observed. The endometrial thickness, typing, and endometrial blood flow resistance index (RI) on the day of injecting HCG, the number of retrieved oocytes, the rate of high quality oocytes, the fertilization rate, the rate of high quality embryos, and the clinical pregnancy rate were respectively compared between the two groups.</p><p><b>RESULTS</b>The scores of SDGDS, SAS, and BDI were improved more obviously in group A than in group B, showing statistical difference (P < 0.01). There was no statistical difference in the endometrial thickness on the day of injecting HCG between the two groups (P > 0.05). The proportion of type A endometrium was 74.5% (38/51 cases) in group A and 45.7% (21/46 cases) in group B, showing statistical difference between the two groups (P < 0.01). The RI was significantly lower in group A (0.48 +/- 0.03) than in group B on the day of injecting HCG (0.52 +/- 0.06, P < 0.01). There was no statistical difference in the number of retrieved oocytes and the fertilization rate between the two groups (P > 0.05). The rate of high quality oocyte, the rate of high quality embryos, and the clinical pregnancy rate were all improved more significantly in group A than in group B, showing statistical difference between the two groups (P < 0.05).</p><p><b>CONCLUSIONS</b>Acupuncture combined CM-MTSSG could obviously alleviate unfavorable emotions as anxiety and depression in patients with IVF-ET, effectively improve the treatment outcomes. Its effects might be correlated with lowering the excitability of the sympathetic nervous system, elevating the quality of oocytes, and improving the endometrial receptivity.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of Er'zhi Tiangui Granule (, ETG) on sequential expressions of integrinβ3 and its ligand osteopontin in the mouse endometrium during controlled ovarian hyperstimulation (COH) and implantation period.</p><p><b>METHODS</b>Seventy-five Mature female Kunming mice were randomly divided into 3 groups, a normal control group, a model group, and a treatment group administrated with ETG for 10 days, 25 in each group. After mated with male mice, every 5 mice were sacrified in each group at the 0, 2nd, 4th, 6th, and 8th days to take their endometrium. In-situ hybridization was used to detect the expressions of integrinβ3 and osteopontin in the endometrium.</p><p><b>RESULTS</b>mRNA expressions of integrinβ3 and osteopontin in the endometrium during implantation period showed similar time sequence rules in the treatment group to those in the normal control group; the peak values of them were a little lower in the treatment group than the normal control without significant differences. In the model group, integrinβ3 mRNA expression was higher at the 2nd day, obviously lower at the 4th and 6th days, and insignificantly lower at the 8th day; and osteopontin expression was remarkably lower at the 4th, 6th, and 8th days, compared with the normal control and the treatment groups (P<0.05, P<0.01).</p><p><b>CONCLUSIONS</b>COH might influence the sequential expressions of integrinβ3 and its ligand osteopontin, bring forward the integrinβ3 expression peak, impact on the cooperation of integrinβ3 and osteopontin, so as to damage the endometrial receptivity. ETG could regulate the sequential expressions of integrinβ3 and its ligand osteopontin to improve the mouse endometrial receptivity during COH.</p>

ABSTRACT

Gemcitabine has high activity against nasopharyngeal carcinoma (NPC). The level of ribonucleotide reductase subunit M1 (RRM1) expression is closely related to the efficacy of gemcitabine on non-small cell lung cancer and pancreatic cancer. However, the expression of RRM1 and its association with sensitivity to gemcitabine-based chemotherapy in advanced NPC is not known. In this study, we retrospectively collected 48 formalin-fixed, paraffin-embedded NPC tissues to evaluate the expression of RRM1 using immunohistochemistry. All patients were diagnosed and treated with gemcitabine-based chemotherapy at Sun Yat-sen University Cancer Center. RRM1 expression was positive in 17(35%) patients. RRM1 expression was not associated with sex, age, performance status, WHO histological type, number of distant metastases, previous treatment, or cycles of gemcitabine-based chemotherapy(P> 0.05). The progression-free survival of the RRM1-positive group was shorter than that of the RRM1-negative group (5 months vs. 7 months, P = 0.036), and the response rate of the RRM1-positive group was somewhat lower than that of the RRM1-negative group (51.6% vs. 35.3%, P = 0.278). There was no significant difference in median survival between the RRM1-positive and RRM1-negative groups (22 months vs. 19 months, P = 0.540). Our results show that RRM1-negative expression is related with longer progression-free survival in advanced NPC patients treated with gemcitabine-based regimens.

ABSTRACT

<p><b>OBJECTIVE</b>To assess the diagnostic value of magnetic resonance imaging (MRI) in the follow-up of patients with hepatocellular carcinomas treated with radiofrequency ablation (RFA) and to compare it with that of computed tomography (CT).</p><p><b>METHODS</b>From December 2009 to September 2011, 40 patients (47 hepatocellular carcinomas) were treated with RFA after transcatheter arterial chemoembolization and underwent MRI and CT for follow-up. RFA margins were assessed on a five-point scale with receiver operating characteristic curve analysis. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were evaluated.</p><p><b>RESULTS</b>The interobserver agreement rate for MRI was significantly higher (Kappa=0.935) than for CT (Kappa=0.714; P < 0.05). The scores of 1 and 5 points for MRI, which confirms the presence or absence of residual tumor, accounted for 89.4% (84/94), while for CT accounting for only 31.9% (30/94). The area under the receiver operating characteristic curve of MRI was significantly higher than that of CT (P < 0.05), as were the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of detection rate (mean, 100%, 96.4%, 76.9%, 100%, and 96.8% for MRI, respectively, vs. 30.0%, 57.1%, 10.3%, 87.7%, and 63.8% for CT).</p><p><b>CONCLUSION</b>MRI is superior to CT in assessing the RFA margins in terms of the diagnostic accuracy and detection rate .</p>

ABSTRACT

<p><b>OBJECTIVE</b>To develop a novel rapid protocol for the detection of occult disseminated tumor cells by a recombinant herpes simplex virus expressing GFP (HSV(GFP)).</p><p><b>METHODS</b>Tumor cells of seven cell lines were exposed to HSV(GFP) and then examined for GFP expression by fluorescence microscopy. Various numbers of tumor cells (10, 100, 1000, 10 000) were mixed into 2 ml human whole blood, separated with lymphocytes separation medium, exposed to HSV(GFP), incubated at 37°C for 6 - 24 h and then counted for the number of green cells under the fluorescence microscope. Some clinical samples including peripheral blood, pleural effusion, ascites, spinal fluid from tumor-bearing patients were screened using this protocol in parallel with routine cytological examination.</p><p><b>RESULTS</b>HSV(GFP) was able to infect all 7 tumor cell lines indicating that the HSV(GFP) can be used to detect different types of tumor cells. The detection sensitivity was 10 cancer cells in 2 ml whole blood. In the clinical samples, there were 4/15 positive by routine cytological examination but 11/15 positive by HSV(GFP), indicating a higher sensitivity of this new protocol.</p><p><b>CONCLUSION</b>Recombinant herpes simplex virus-mediated green fluorescence is a simple and sensitive technique for the identification of occult disseminated cancer cells including circulating tumor cells (CTCs).</p>

ABSTRACT

<p><b>OBJECTIVE</b>To screen and diagnose Down's syndrome during mid-term pregnancy to reduce the number of babies with Down's syndrome.</p><p><b>METHODS</b>With the multi-level of stratified cluster sampling, twenty thousand and eight hundred and three women at 15-20 weeks gestation were screened by maternal serum AFP and beta-hCG using the time resolved fluoroimmunoassay (TRFIA). Then the screened high-risk women were diagnosed by amniocentesis, cell culture and chromosome analyses. The born children were diagnosed by follow-up and peripheral blood chromosome analyses.</p><p><b>RESULTS</b>Six fetuses were diagnosed by serum screening and amniotic fluid chromosome analyses, and 3 born children were diagnosed by follow-up and peripheral blood chromosome analyses. Nine cases of Down's syndrome were detected in total, with the positive prenatal screen rate being 67% (6/9).</p><p><b>CONCLUSION</b>The prenatal screening and diagnosis can reduce the birth of Down's syndrome patients and improve the population quality. However, the diagnosis accuracy still needs to be improved to further reduce the false negative rate and prevent misdiagnosis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To assess the risk factors of stress-related ulcer and gastrointestinal hemorrhage after pancreaticoduodenectomy.</p><p><b>METHODS</b>From May 1999 to July 2007, 285 periampullary cancer patients underwent pancreaticoduodenectomy in our hospital. The clinical data, pathological results, type of operation, and postoperative treatment were retrospectively analyzed. Patients with stress-related ulcer and gastrointestinal hemorrhage were selected for risk factor analysis, and other patients were taken as control group.</p><p><b>RESULTS</b>35 patients (12.3%) developed stress-related ulcer and gastrointestinal hemorrhage following pancreaticoduodenectomy. Pathological examination showed pancreatic cancer in 5 cases, duodenal cancer in 8, common bile duct cancer in 10, ampullary carcinoma in 11, and solid-pseudopapillary tumors in 1. Single variate analysis demonstrated that alcohol, preoperative bilirubin level, operation time, lymph node metastasis, prealbumin decrease after operation and other complication were significantly associated with the stress-related ulcer and gastrointestinal hemorrhage. Logistic regression in multivariate analysis revealed that preoperative bilirubin level, operation time, other complication, prealbumin decrease after surgery were independent risk factors.</p><p><b>CONCLUSION</b>Stress-related ulcer and gastrointestinal hemorrhage are one of the most common complications after pancreaticoduodenectomy. Preoperative bilirubin level, operation time, other complications, and prealbumin decrease after operation are four independently risk factors.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinicopathological characteristics, diagnostic methods and prognosis of small pancreatic cancer.</p><p><b>METHODS</b>From May 2000 to January 2007, 89 patients with pancreatic cancer underwent surgery in our hospital. Of those, 14 had a tumor < or = 2 cm in diameter (small tumor group), and the other 75 had a tumor >2 cm in diameter (controlled group). The clinicopathological data of all the cases were retrospectively reviewed and analyzed.</p><p><b>RESULTS</b>In the small pancreatic cancer group, CT and MRI detected 66.7% (8/12) and 77.8% (7/9) of the tumors, respectively. Serosal infiltration was found in 2 cases, lymph node involvement in 3 cases, and retroperitoneal infiltration in 3 cases. The follow-up duration of this group was 4-86 months. The overall 3- and 5-year survival rates were 42.8% and 31.7%, while in the control group, the overall 3- and 5-year survival rates were 29.7% and 22.5%, respectively. The multivariate analysis showed that the lymph node involvement, serosal infiltration and retroperitoneal infiltration were independent risk factors (P<0.05). However, the tumor size was not shown to be an independent risk factor (OR value = 1.45, P = 0.971).</p><p><b>CONCLUSION</b>CT and MRI are valuable in detecting small pancreatic cancer. Small pancreatic cancers are likely to have a better prognosis when compared with larger ones. Lymph node metastasis and local infiltration are independent predictors of prognosis but not tumor size.</p>
