RESUMO
The preoperative nutritional and immunological statuses have an important impact in predicting the survival outcome of patients with various types of malignant tumors. Our study aimed to explore the clinical significance and predictive prognostic potential of Onodera's prognostic nutritional index (PNI) in patients with colorectal carcinoma. This retrospective study included a total of 1321 patients who were diagnosed with colorectal cancer and who had been surgically treated between January 1994 and December 2007. The PNI level was determined according the following formula: 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (per mm(3)). The impact of PNI on clinicopathological features and overall survival (OS) was determined. The optimal cutoff value of PNI was set at 45. Patients in the low-PNI group had a greater potential to have aggressive histological features, advanced tumors (T), nodal involvement (N), metastasis (M), and TNM stage than those in the high-PNI group. The low-PNI group had a worse OS than the high-PNI group (5-year survival rate 56.1 vs 64.8 %, respectively; P < 0.05). Furthermore, the PNI value was an independent prognostic factor for colorectal cancer in this study. The OS was significantly lower in the low-PNI group than in the high-PNI group in patients with TNM stage II and III diseases. Preoperative PNI is a simple and useful marker to predict clinicopathological features and long-term survival outcome in patients with colorectal carcinoma. PNI analysis should be included in the routine assessment of patients with locally advanced colorectal cancer.

PURPOSE: Malignancies of the anal canal are rare diseases associated with limited reports and insufficient data. The purpose of this study was to evaluate the spectrum of pathological subtypes, therapeutic modalities and prognosis of patients in the Chinese population with anal canal malignancies. METHODS: A retrospective consecutive series of patients with malignancies of the anal canal at 4 institutions in China between January 1990 and December 2011 was studied. The patient demographic data, including age, gender, tumor stage, initial symptoms, pathological diagnosis, treatment and survival, were collected and analyzed from the hospitals' databases. RESULTS: A total of 180 patients (90 males, 90 females) with anal canal malignancies was identified. Their median age was 58 years (range 17-88). The 3 most common pathological subtypes were adenocarcinoma (N-129, 71.7%), squamous cell carcinoma (SCC; N=21, 11.7%) and melanoma (N7equals;15, 8.3%). Ninety-five adenocarcinoma patients and 10 SCC patients were managed with abdominoperineal resection (APR). With a median follow-up time of 28.9 months (range 1-173), the 5-year overall survival (OS) rates for all patients, adenocarcinoma patients, SCC patients and melanoma patients were 41.9, 40.6, 44.5 and 14.8% respectively, and the median OS time were 46.8, 50.1, 52.5 and 25.0 months, respectively (p=0.173). CONCLUSION: Adenocarcinoma was the major histological subtype in Chinese patients with anal canal malignancies. APR-based combined modality treatment was the first choice for the past two decades, whereas multidisciplinary treatment was not performed adequately. The management of SCC must be standardized in South China population. In the future, randomized clinical trials are warranted for the optimal treatment options of anal canal adenocarcinoma patients.

BACKGROUND Laparoscopic-perineal neovagina construction by sigmoid colpoplasty is a popular therapeutic approach for patients with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome. The conventional approach requires an auxiliary abdominal incision to exteriorize the descending colon to fix the anvil for end-to-end colorectal anastomosis. We modified the natural orifice specimen extraction surgery (NOSES) approach by exteriorizing the descending colon through the artificial neovaginal tunnel to replace the anvil extracorporeally, without requiring an auxiliary abdominal incision. It was a more minimally invasive technique. CASE REPORT We performed this modified laparoscopic-perineal sigmoid colpoplasty in a 26-year-old woman with MRKH syndrome. We cut off a segment of the sigmoid colon with a vascular pedicle to make a new vagina out of it, the same as in the traditional laparoscopic-perineal sigmoid colpoplasty. What is new about this technique is that it has no need for abdominal incision and is more minimally invasive. The operating time was 315 min. No postoperative complications occurred. The postoperative hospital stay was 4 days. The modified laparoscopic-perineal approach, free from an auxiliary abdominal incision, demonstrated advantages, including a shorter hospital stay, expedited recovery, and comparable anatomical outcomes, when compared with the traditional approach. This innovation improves the surgical experience for patients with MRKH syndrome, addressing the physical and psychological aspects of their condition. CONCLUSIONS This refined laparoscopic-perineal neovagina construction by sigmoid colpoplasty represents a feasible and minimally invasive technique. It is an attractive option for MRKH syndrome patients in need of vaginal reconstruction, offering a streamlined procedure with reduced postoperative recovery time and enhanced patient outcomes.

OBJECTIVE: To explore the impact of clinicopathological features and extent of lymph node dissection on the prognosis in early gastric cancer (EGC) patients. METHODS: A total of 142 EGC cases screened from database of gastric cancer of Sun Yat-sen University, from Aug. 1994 to Jan. 2010, were included in this study. According to the lymph node metastasis status, they were divided into lymph node negative (n = 116) and lymph node positive (n = 26) groups. The clinicopathological features of the two groups and the impact of extent of lymph node dissection on the prognosis were analyzed. RESULTS: There were no significant differences in age, gender, tumor size and location, Borrmann typing, WHO TNM staging, histological typing, and CEA value between the two groups (P > 0.05). The TNM stages in the lymph node positive group were higher than that in the lymph node negative group (P < 0.001). Between the cases who underwent D1 (n = 21) and D2 (n = 121) dissection, there were no significant differences in postoperative hospital days, blood transfusion volume, and operation time (P > 0.05). The median numbers of LN dissected in D1 and D2 cases were 4 (0 to 16) and 20 (12 to 30), with a significant difference (P = 0.000), but the number of positive LN without significant difference (P = 0.502). The postoperative complication rates were 9.5% in the D1 and 3.3% in the D2 dissection groups, without a significant difference (P = 0.128). The median survival time of the lymph node negative and positive groups was 156 vs. 96 months (P = 0.010). In cases who received D2 and D1 lymph node dissection, the median survival time (MST) was 156 vs. 96 months (P = 0.0022). In the lymph node positive group, D2 dissection prolonged survival time significantly than D1 dissection (96 vs. 27months) (P = 0.001). Cox regression analysis showed that the extent of lymph node dissection and LN metastasis were independent prognostic factors for EGC patients. CONCLUSIONS: It is not able to accurately assess the LN metastasis status preoperatively according to the routine clinicopathological features. For the patients with unknown LN metastasis status, D2 dissection should be the first choice. Comparing with D1 dissection, the morbidity of D2 dissection are not increased, but survival time is prolonged.

OBJECTIVE: To screen and collect the familial gastric cancer (FGC) kindreds for exploring its clinicopathological characteristics and prognosis. METHODS: A cross-sectional study was performed among 3640 patients with gastric cancer at 5 hospitals in Guangdong province between 2000 and 2007 and FGC kindreds were diagnosed according to the Amsterdam criteria. Their pedigree features and cancer incidence were analyzed. Clinical characteristics and prognosis were compared between FGC and sporadic gastric cancer (SGC) patients. Survival curves and overall five-year survival rates were established according to the Kaplan-Meier and Log-rank methods. Hazard ratios for death were calculated by Cox regression analysis. RESULTS: A total of 112 FGC kindreds (3.1%) were diagnosed among 3640 gastric cancer patients. In these 112 FGC families, 182 malignant tumors were diagnosed in the first- and second-degree relatives. Gastric cancer (n = 154, 84.6%), esophageal cancer (n = 8, 4.4%) and lung cancer (n = 6, 3.3%) were most common tumors. Tumor types in male proband families did not differ from those in female counterparts (P = 0.644). Most tumors occurred in the first-degree relatives and the ratio of male-to-female was 106:44. The mean age of FGC patients at 54 years was 10 years younger than that of SGC patients. No differences existed in tumor size, tumor location, Borrmann type, pT or pN between the FGC and SGC patients. The overall 5-year survival was 56.0% for FGC patients and 48.8% for SGC patients. Univariable (P = 0.287) and multivariable (HR = 1.101, P = 0.807) analyses demonstrated that FGC was not a significant prognostic factor. CONCLUSIONS: Gastric cancer is the most common cancer in FGC families. The first-degree male relatives are at a high risk of developing gastric cancer. Not particular clinical characteristics but pedigree examination facilitates the diagnosis of FGC.

OBJECTIVE: To elucidate the mechanism of Hedgehog pathway in the metastasis of gastric cancer and examine particularly the effect on epithelial-mesenchymal transition (EMT). METHODS: Using pharmacological and siRNA knockdown approach, the Hedgehog pathway was inhibited. The cellular morphology, protein level, invasion and metastatic abilities were measured by microscope, Western blot, Transwell invasion assay and Transwell migration assay. RESULTS: Under the inhibition of Hedgehog pathway, the invasive and migration abilities of gastric cancer decreased. The transforming growth factor (TGF) -ß could induce spindle-like-shaped morphological changes with a down-regulation of epithelial characteristic (decreased E-cadherin protein level) and an up-regulation of mesenchymal characteristics (increased Vimentin protein level). There were concurrent increases of invasive and migration potentials by 3 and 4 folds respectively.However, under the continuous stimulation of TGF-ß, the inhibition of Hedgehog pathway could reverse the EMT changes, lower the expression of vimentin and reduce the invasion and metastatic abilities by 3 and 2 folds respectively. CONCLUSIONS: The inhibition of Hedgehog pathway can decrease the TGF-ß-inducing EMT.It suggests that Hedgehog pathway may play a critical role in the metastasis of gastric cancer.

OBJECTIVE: To explore the risk factors and prognostic impact of duodenal hepatic ligamentous lymph node (No.12 LN) metastasis in cases with curable advanced distal gastric cancer. METHODS: The data of 379 cases with advanced distal gastric cancer undergoing radical resection were screened from the Database of Gastric Cancer Center of Sun Yat-sen University from January 1997 to December 2010. According to No.12 LN metastasis, they were divided into negative (n = 339) and positive (n = 40) groups. Their clinicopathological parameters and surgical regimens were compared. And the risk factors and prognostic impact of No.12 LN metastasis were analyzed. RESULTS: No significant inter-group difference existed in gender, age, infiltration depth or differentiation degree (all P > 0.05). In negative and positive groups, the percent of tumor size ≥ 5 cm was 30.1% (102/339) vs 55.0% (22/40), lymph node metastasis N3 stage 8.3% (28/339) vs 42.5% (17/40), other lymph nodes except for No.12 metastasis 70.2% (238/339) vs 92.5% (37/40), distal metastasis M1 10.9% (37/339) vs 32.5% (13/40), TNM stage IV 18.6% (63/339) vs 65.0% (26/40), infiltration Borrmann type 74.3% (252/339) vs 92.5% (37/40), non-adenocarcinoma 15.9% (54/339) vs 35.0% (14/40) and positive serum-carcinoembryonic antigen (S-CEA) 12.7% (43/339) vs 32.5% (13/40). There were all with significant difference (all P < 0.01). Logistic regression analysis showed tumor size ≥ 5 cm, lymph node (except for No.12) metastasis, distal metastasis and positive S-CEA were independent risk factors of No.12 LN metastasis (OR = 2.144, 3.581, 2.597, 2.552; P = 0.035, 0.042, 0.019, 0.022 respectively). Cox regression analysis showed lymph nodes (except for No.12) and No.12 metastasis, distal metastasis and Borrmann type were independent prognostic factors for all cases. In negative and positive groups, median survival time was 63.0 versus 12.0 months with significant difference (P = 0.000). CONCLUSIONS: For cases with curable advanced distal gastric cancer, No.12 LN metastasis was an independent prognostic factor. No.12 LN should be dissected thoroughly in cases with tumor size ≥ 5 cm, lymph nodes (except No.12) metastasis, distal metastasis and positive S-CEA.

The continuation of the COVID-19 pandemic has caused a decline in people's subjective well-being and emotional states. Digital travel based on 360° videos provides an alternate way for people to improve their mental health at home during this specific period. Yet, how to construct effective digital travel content that improves emotions remains an issue. This investigation assessed the impact of people's perceived presence and sense of place (SOP) on emotional improvement during a 360° digital travel experience. A total of 156 undergraduate students volunteered to participate, and anxiety, emotion levels, and life satisfaction were measured before and after the digital travel experience; presence and SOP ratings were also collected after the experience. A Latent Change Score model was then developed, and the results indicated that the greater presence and SOP individuals experienced during their digital travel, the better their digital travel experience and emotional improvement. Furthermore, the current data highlight that SOP has a greater impact on emotional improvement than presence. This result provides a novel understanding that how SOP is generated may be more critical to digital travel than presence. This new understanding should help improve relevant applications in the field of digital travel, such as the possibility of providing meaningful narrative context in a virtual environment to induce SOP more effectively, and improve the digital travel experience. Overall, the findings of this study expand our understanding of the digital travel experience and lay the groundwork for future research on SOP and digital travel.

BACKGROUND AND OBJECTIVES: The purpose of this study was to clarify the relationship of hepatocyte growth factor (HGF), c-Met, and E-cadherin with clinicopathological parameters and prognosis in gastric carcinoma (GC). METHODS: 114 specimens were collected from GC patients and expression of HGF, c-Met, and E-cadherin in tissue microarray was evaluated by immunohistochemical staining. Correlation between immunostainings and clinicopathological parameters, follow-up data of patients, was analyzed statistically. RESULTS: Abnormal E-cadherin expression was found in 60.5% (69/114) and associated with tumor depth (P = 0.003), lymph node metastasis (P = 0.001) and advanced clinical stage (P = 0.001). High-expression of HGF and c-Met were found in 64.0% (73/114) and 82.4% (94/114), respectively. High c-Met expression was significantly associated with advanced clinical stage (P = 0.001) and lymph node metastasis (P = 0.011) of GC. In univariate survival analysis, high-expression of HGF and c-Met, and abnormal E-cadherin were significantly associated with poor prognosis of GC patients. However, only abnormal E-cadherin expression (P = 0.001) and tumor depth (P = 0.010) emerged as strong independent prognostic factors for overall survival of GC patients. CONCLUSION: We found significant correlation among HGF/c-Met, E-cadherin expression and worse prognosis of patients with GC. Abnormal E-cadherin expression may serve as an independent predictive factor for prognosis of GC patients.

BACKGROUND AND OBJECTIVES: This study was conducted to investigate whether and how macrophages recruited to tumor microenvironments (tumor-associated macrophages, TAMs) were involved in angiogenesis and lymphangiogenesis of gastric cancer (GC). METHODS: TAMs, microvessel density (MVD), and lymphatic vessel density (LVD) in 115 cases of GC tissue were assessed by immunohistochemistry (IHC) staining of CD68, CD34, and D2-40, respectively. Preoperative blood samples from 43 patients were obtained to detect serum levels of vascular endothelial growth factor (VEGF) and VEGF-C. A co-culture system was also developed to study effects and underlying mechanisms of THP-1 macrophages on SGC7901 GC cells. RESULTS: TAMs numbers were closely related to serosa invasion, lymph node metastasis and tumor, nodes, and metastases stage and a positive correlation existed between the TAMs count and MVD and LVD. Additionally, TAMs were associated with preoperative serum levels of VEGF and VEGF-C, the expression of VEGF and VEGF-C protein in macrophages was up-regulated in the co-culture system, and inhibition of the NF-κB pathway in macrophages induced a significant reduction in the expression of VEGF and VEGF-C in both macrophages and GC cells (all P<0.05). CONCLUSIONS: TAMs may promote angiogenesis and lymphangiogenesis of GC, possibly by enhancing VEGF and VEGF-C expression.

OBJECTIVE: To compare Borrmann type IV gastric cancer with other types of cancer and explore their clinicopathological features and prognostic factors. METHODS: We retrospectively reviewed the medical records of 893 consecutive advanced gastric cancer patients. They were divided into 2 groups: Borrmann type IV (n = 139) and other macroscopic Borrmann types of cancer (n = 754). Their clinicopathologic characteristics and overall survival data were analyzed. RESULTS: Borrmann type IV gastric cancer was found to be associated with more advanced and unfavorable clinicopathological features. The incidence of preoperative biopsy-negative rate of Borrmann type IV gastric cancer was much higher (15.9%) than other Borrmann types of gastric cancer. The 5-year survival rate of Borrmann type IV cancer patients was 9.9% and it was significantly lower than that of other types. Moreover, the 5-year survival rate was higher in the patients with curative resection (18.7%) (P < 0.05). Stratified analysis revealed that when the tumor TNM stages were of II, III, the survival data of Borrmann type IV cancer were worse than others. Multivariate analyses revealed distant metastasis and curability were independent prognostic factors for Borrmann type IV gastric cancer. CONCLUSIONS: Borrmann type IV carcinoma has poor clinicopathological features and survival rate compared with other types. An early detection and curative resection may improve the prognosis for the patients with Borrmann type IV cancer.

OBJECTIVE: To evaluate the rationality of different radical operative modalities for proximal gastric cancer. METHODS: A total of 366 cases of proximal gastric cancer undergoing radical dissection were screened from data base. According to the operative modalities, they were divided into proximal gastrectomy group (PG) (n = 77) and total gastrectomy group (TG) (n = 289). Through the comparisons of clinical pathologic features, surgical profiles, postoperative complications, postoperative quality-of-life and prognosis in two groups, the rationality of different operative modalities was evaluated. RESULTS: No significant differences existed in age, gender or carcinoembryonic antigen (CEA) value between two groups (all P > 0.05). The rates of tumor diameter ≥ 5 cm, organic infiltration, lymph nodes metastasis, distal organs metastasis, infiltrative type, poorly differentiated tumor in PG and TG groups were 15.6% (12/77) vs 49.8% (144/289), 16.9% (13/77) vs 37.7% (109/289), 67.5% (52/77) vs 79.9% (231/289), 3.9% (3/77) vs 11.4% (33/289), 45.5% (35/77) vs 68.9% (199/289), 32.5% (25/77) vs 57.8% (167/289) respectively (all P < 0.05). Operative duration, volume of blood transfusion, number of dissected lymph nodes and positive lymph nodes, rate of combined organic resection and complications in groups of PG and TG were (256 ± 83) vs (298 ± 86)min, 0 vs 400 ml, 15 ± 12 vs 26 ± 15, 0 vs 3, 15.6% (12/77) vs 43.2% (125/289), 14.3% (11/77) vs 7.6% (22/289) respectively (all P < 0.05). In two groups, the evaluating indices of postoperative quality-of-life showed no significant differences (P > 0.05). In two groups, the median survival time of the cases with tumor diameter < 5 cm, no-organic infiltration, no-peri-tumor lymph nodes metastasis, no-distal organic metastasis had no significant difference (all P > 0.05). However, in groups of PG and TG, the median survival time of the cases with tumor diameter ≥ 5 cm, organic infiltration, peri-tumor lymph nodes metastasis and distal organic metastasis was 15.0 months vs 29.0 months, 15.0 months vs 30.0 months, 34.0 months vs 45.0 months, 4.0 months vs 18.0 months respectively(all P < 0.05). CONCLUSION: As compared with radical proximal gastrectomy, radical total gastrectomy improves significantly the prognosis of patients of proximal gastric cancer with organic infiltration, peri-tumor lymph nodes metastasis, distal organic metastasis and tumor diameter ≥ 5 cm.

OBJECTIVE: To explore the effects of fast-track surgery on postoperative humoral immune function in patients undergoing elective colorectal resection. METHODS: Seventy patients with colorectal carcinoma requiring colorectal resection were randomized into fast-track group (n = 35) and conventional care group (n = 35). The clinical parameters and markers of humeral immune function were evaluated in both groups postoperatively. RESULTS: Sixty-two patients finally completed the study, including 32 in the fast-track group and 30 in the conventional care group. There was a significantly faster recovery of postoperative humoral immunity: blood levels of globulin (24.1 ± 2.4 vs 22.1 ± 3.3 g/L, P = 0.025), immunoglobulin G (10.79 ± 2.39 vs 8.66 ± 2.09 g/L, P = 0.007) and complement 4 (0.24 ± 0.09 vs 0.17 ± 0.05 g/L, P = 0.035) at Day 3 postoperation were higher in the fast-track group than in the conventional care group. And there was also a significantly shorter length of postoperative stay (6.0 ± 1.0 vs 11.7 ± 3.8 d, P < 0.001) in patients undergoing fast-track rehabilitation. CONCLUSION: Fast-track surgery accelerates the recovery of postoperative humoral immune function in elective surgery for colorectal carcinoma with a shorter length of postoperative hospital stay.

OBJECTIVE: To investigate the effects of fast track surgery on postoperative insulin sensitivity on the basis of clinical benefits in patients undergoing elective open colorectal resection. METHODS: During May 2008 to December 2008, Seventy patients with colorectal carcinoma requiring colorectal resection were randomized into two groups: a fast track group (35 cases) and a conventional care group (35 cases). All included patients received elective open colorectal resection with combined tracheal intubation and general anesthesia. Clinical parameters, stress markers and insulin sensitivity were evaluated in both groups. RESULTS: The 62 patients finally completed the study, 32 cases in the fast-track group and 30 cases in the conventional care group. The speed of recovery of postoperative insulin sensitivity on 7 days postoperative in the fast-track group (97% ± 9%) was significantly faster than the conventional care group (88.5% ± 9.0%, t = 2.552, P = 0.016). The hospitalization days in the fast-track group was 6 days (M(50)), and it was significantly shorter than the conventional care group ((11.7 ± 3.8) days, Z = 4.360, P = 0.000). The time of recovery of bowel function were faster in the fast-track group (time to pass flatus was 2 days (M(50))) than the conventional care group (4 days, Z = 3.976, P = 0.000). The Infectious complication rate in the fast-track group (2/32) is lower than the other group (8/30, P = 0.040). CONCLUSION: Fast track surgery accelerates recovery of postoperative insulin sensitivity in elective surgery for colorectal carcinoma with a lower rate of postoperative infectious complications and a shorter length of postoperative hospital stay.

OBJECTIVE: To evaluate the impact of different gastrectomy and reconstruction method on prognosis and quality of life in proximal gastric cancer. METHODS: The 265 cases of proximal gastric cancer received radical resection, according to gastrectomy or reconstruction method, were divided into proximal gastrectomy/gastroesophagostomy group (PG) (n = 63) and total gastrectomy/esophagojejunostomy group (TG) (n = 202). The clinical pathologic features, prognosis, postoperative quality of life in 2 groups were compared. RESULTS: There had no significant differences in age, gender, CEA value between two groups (all P > 0.05). In PG and TG group, tumor size (cm), ratio of organic invasion, lymph nodes metastasis, distal metastasis, TNM IV stage, Borrmann typing, poor or undifferentiated carcinoma was 2.9 ± 1.9 vs. 4.8 ± 2.8, 9.5% vs. 32.2%, 64.7% vs. 70.6%, 0 vs. 8.4%, 6.9% vs. 31.8%, 44.4% vs. 69.2%, 31.7% vs. 53.7%, respectively, all with significant difference (t = -6.260, χ(2) = 29.473, 14.559, 5.665, 32.483, 12.588, 10.954, all P < 0.05). In PG and TG group, the ratio of D3 and D3(+) resection, multi-visceral resection, complications was 0 vs. 13.8%, 9.5% vs. 38.6%, 7.9% vs. 1.5% respectively, showed increasing range of resection and decreasing complications significantly in TG group (all P < 0.05). The median survival time (months) was 62.5 vs. 78.9 in TG and PG group respectively, without significant difference (P > 0.05). In 2 groups, the evaluation index of post-operative quality of life without significant differences (P > 0.05). CONCLUSIONS: For proximal gastric cancer, although the cases received TG with worse clinicopathological features, which prognosis was similar to that received PG. The postoperative quality of life without significant difference between the cases received gastroesophagostomy and esophagojejunostomy.

Executive functions (EFs) are essential for early childhood development, and effective programs to improve EFs in preschool education are becoming increasingly crucial. There is rising evidence that combined physical-cognitive intervention training utilizing active video games (exergames) could be a viable strategy to improve EFs. However, there is a shortage of empirical evidence on the application of this approach in preschool education. The effectiveness of exergame intervention training in preschools must be evaluated. This study conducted a randomized controlled trial to assess the effects of exergames intervention training on preschool children's EFs. A total of 48 participants aged 4-5 years were enrolled; 24 were randomly allocated to receive exergames physical activity training, and the remaining 24 received conventional physical activity training. After a four-week intervention, the children who received the exergames intervention training exhibited considerably greater gains in all three EFs tasks than children who received the conventional physical activity program. Follow-up interviews revealed that the children accepted the exergames well. The results demonstrate the viability of incorporating exergames into preschool education to improve children's EFs, supporting prior findings and offering more empirical evidence from early childhood research.

BACKGROUND: The outcomes of the use of commercial in vitro maturation (IVM) medium to culture immature oocytes obtained from conventional ovulation induction, followed by rescue intracytoplasmic sperm injection (RICSI), are not ideal. It is thus difficult to widely adopt this approach in clinical practice. Therefore, it is necessary to explore methods for improving the clinical outcome of IVM. AIM: To study the effect of sperm on the developmental potential of in vitro-matured oocytes in conventional culture. METHODS: This was a retrospective study of patients whose immature oocytes were harvested from conventional oocyte stimulation cycles and underwent ICSI at our hospital between June 2018 and August 2020. RICSI was performed using sperm collected on the day of oocyte harvest (old) and sperm collected on the day of RICSI (fresh) and oocytes matured in vitro after 24 h of culture in conventional medium. The rates of in vitro oocyte maturation, normal fertilization, normal cleavage, day-3 top-quality embryos, and useful blastocyst formation were compared between the two groups. RESULTS: In total, 102 germinal vesicle (GV)-stage immature oocytes were cultured in the old sperm group. In the fresh sperm group, 122 GV-stage immature oocytes were collected and cultured in vitro for 24 h. There were no significant differences in the general conditions of males and females between the two groups (P > 0.05). The oocyte maturation, normal fertilization, and normal cleavage rates of the old and fresh groups were 51.0% vs 55.7%, 61.5% vs 64.7%, and 93.8% vs 93.2%, respectively. None of the rates differed significantly (P > 0.05) between the two groups. However, the day-3 top-quality embryo and useful blastocyst rates of the old and fresh sperm groups were 16.6% vs 63.4%; 6.67% vs 34.6%, respectively. The day-3 top-quality embryos and useful blastocyst rates of the old sperm group were significantly lower than those of the fresh group (P < 0.05). CONCLUSION: In vitro maturation with conventional culture medium combined with the use of fresh sperm collected on the day of RICSI is an easy-to-implement strategy for patients whose oocytes are completely or mostly immature.
RESUMO
OBJECTIVE: To compare the reconstructing safety of pancreaticogastrostomy (PG) versus pancreaticojejunostomy (PJ) after pancreaticoduodenectomy (PD). METHODS: The articles of prospectively controlled trials published until late December 2010 comparing PJ and PG after PD were searched by the means of MEDLINE, EMBASE, Cochrane Controlled Trials Register databases and Chinese Biomedical Database. After quality assessment of all included prospective controlled trials, a meta-analysis was performed with Review Manager 5.0 for statistic analysis. RESULTS: A total of 6 prospective controlled trials were included. Among 867 patients analyzed, 440 underwent PG and 426 PJ. A meta-analysis of 6 prospective controlled trials (including randomized control trial (RCT) and non-randomized prospective trial) revealed significant differences between PJ and PG regarding the overall postoperative complication rates [OR 0.53, 95%CI (0.30, 0.95), P = 0.03], pancreatic fistula [OR 0.47, 95%CI (0.22, 0.97), P = 0.04] and intra-abdominal fluid collection [OR 0.42, 95%CI (0.25, 0.72), P = 0.001]. The differences in biliary fistula, intra-abdominal (IAC) complications and mortality were of no significance. Meta-analysis of 4 RCTs revealed significant differences between PJ and PG regarding intra-abdominal fluid collection [OR 0.46, 95%CI (0.26, 0.79), P = 0.005]. The differences in pancreatic fistula, overall postoperative complications, biliary fistula, intra-abdominal complications and mortality were of no statistical significance. CONCLUSION: Through a meta-analysis of 6 prospective controlled trials, there are significant differences between PJ and PG regarding overall postoperative complications, pancreatic fistula and intra-abdominal fluid collection. Significant differences exist between PJ and PG regarding intra-abdominal fluid collection. The safety profiles of PG and PJ are comparable.

OBJECTIVE: To explore the application value of next generation sequencing (NGS) in preimplantation genetic diagnosis of α/ß complex thalassemia couple. METHODS: The coding regions of α-globin genes (HBA1, HBA2) and ß-globin gene (HBB) were selected as the target regions. The high-density and closely linked single nucleotide polymorphism (SNP) sites were selected as the genetic linkage markers in the upstream and downstream 2M regions of the gene. After NGS, the effective SNP sites were selected to construct the haplotype of the couple, and the risk chromosome of the mutation carried by the couple was determined. The NGS technology was used to sequence the variations of HBA1, HBA2 and HBB directly and construct haplotype linkage analysis for preimplantation genetic diagnosis. RESULTS: Direct sequencing and haplotype linkage analysis of HBA1, HBA2 and HBB showed that two of the six blastocysts were α/ß complex thalassemia, one was ß-thalassemia heterozygote, two were α-thalassemias heterozygotes, and one was intermediate α-thalassemia. A well-developed embryo underwent preimplantation genetic diagnosis was implanted into the mother's uterus, and a healthy infant was born at term. CONCLUSION: Preimplantation genetic diagnosis can be carried out by NGS technology in α/ß complex thalassemia couples, and abortion caused by aneuploid embryo selection can be avoided.
