Background::Differentiated thyroid cancer (DTC) is commonly diagnosed in women of child-bearing age, but whether pregnancy influences the prognosis of DTC remains controversial. This study aimed to summarize existing evidence regarding the association of pregnancy with recurrence risk in patients previously treated for DTC.Methods::We searched PubMed, Embase, Web of Science, Cochrane, and Scopus based on the prespecified protocol registered at PROSPERO (CRD42022367896). After study selection, two researchers independently extracted data from the included studies. For quantitative data synthesis, we used random-effects meta-analysis models to pool the proportion of recurrence (for pregnant women only) and odds ratio (OR; comparing the risk of recurrence between the pregnancy group and the nonpregnancy group), respectively. Then we conducted subgroup analyses to explore whether risk of recurrence differed by response to therapy status or duration of follow-up time. We also assessed quality of the included studies.Results::A total of ten studies were included. The sample size ranged from 8 to 235, with participants’ age at pregnancy or delivery ranging from 28 to 35 years. The follow-up time varied from 0.1 to 36.0 years. The pooled proportion of recurrence in all pregnant patients was 0.13 (95% confidence intervals [CI]: 0.06-0.25; I2: 0.58). Among six included studies reporting response to therapy status before pregnancy, we observed a trend for increasingly higher risk of recurrence from excellent, indeterminate, and biochemically incomplete to structurally incomplete response to therapy ( Ptrend <0.05). The pooled risk of recurrence in the pregnancy group showed no evidence of a significant difference from that in the nonpregnancy group (OR: 0.75; 95% CI: 0.45-1.23; I2: 0). The difference in follow-up time (below/above five years) was not associated with either the proportion of recurrence in all pregnant patients ( P >0.05) or the OR of recurrence in studies with a comparison group ( P >0.05). Two included studies that focused on patients with distant metastasis also did not show a significant difference in disease recurrence between pregnancy and nonpregnancy groups (OR: 0.51 [95% CI: 0.14-1.87; I2: 59%]). Conclusion::In general, pregnancy appears to have a minimal association with the disease recurrence of DTC with initial treatment. Clinicians should pay more attention to progression of DTC among pregnant women with biochemical and/or structural persistence.Registration::PROSPERO, https://www.crd.york.ac.uk/PROSPERO/; No. CRD42022367896.

Based on observing the cytological characteristics of the flower buds of the functional male sterile line (S13) and the fertile line (F142) in eggplant, it was found that the disintegration period of the annular cell clusters in S13 anther was 2 days later than that of F142, and the cells of stomiun tissue and tapetum in F142 disintegrated on the blooming day, while it did not happen in S13. The comparative transcriptomic analysis showed that there were 1 436 differential expression genes (DEGs) (651 up-regulated and 785 down-regulated) in anthers of F142 and S13 at 8, 5 days before flowering and flowering day. The significance analysis of GO enrichment indicated that there were more unigene clusters involved in single cell biological process, metabolism process and cell process, and more catalytic activity and binding function were involved in molecular functions. Through KEGG annotation we found that the common DEGs were mainly enriched in the biosynthesis of secondary metabolites, metabolic pathway, protein processing in endoplasmic reticulum, biosynthesis of amino acids, carbon metabolism and plant hormone signal transduction. The fifteen genes co-expression modules were identified from 16 465 selected genes by weighted gene co-expression network analysis (WGCNA), three of which (Plum2, Royalblue and Bisque4 modules) were highly related to S13 during flower development. KEGG enrichment showed that the specific modules could be enriched in phenylpropanoid biosynthesis, photosynthesis, porphyrin and chlorophyll metabolism, α-linolenic acid metabolism, polysaccharide biosynthesis and metabolism, fatty acid degradation and the mutual transformation of pentose and glucuronic acid. These genes might play important roles during flower development of S13. It provided a reference for further study on the mechanism of anther dehiscence in eggplant.

Objective: To compare the long-term outcomes in ST-elevation myocardial infarction (STEMI) patients who underwent early or late delayed percutaneous coronary intervention (PCI) using drug-eluting stents (DES). Methods: This study was a retrospective, observational and single-center study. Consecutive STEMI patients (n=977), who admitted to Fuwai Hospital in 2013 and underwent successful selective PCI using drug-eluting stents (DES) within 3 to 35 days after symptom onset were enrolled and divided into the early delayed PCI (3-14 d) group (n=495) and the late delayed PCI (15-35 d) group (n=482). General clinical data of the patients and related data of coronary angiography and interventional therapy were collected, and the endpoint events were followed up. The primary endpoint was 2-year major adverse cardiac and cerebrovascular events (MACCE) including cardiac death, recurrent myocardial infarction, definite or probable stent thrombosis and ischemic stroke. The secondary endpoint was 2-year ischemia-driven target vessel revascularization. The incidence of endpoint events of the two groups was compared, and it was compared again after the primary baseline characteristics such as age and gender were matched by the propensity scoring method at a 1∶1 ratio. Results: A total of 910 (93.1%) patients who underwent delayed PCI were transferred from other hospitals, and 292 (29.9%) patients received thrombolysis before PCI. The time interval before PCI was 14 (10, 20) days. The incidence of 2-year MACCE (3.0%(15/495) vs. 2.3%(11/482), P=0.468) and ischemia-driven target vessel revascularization (3.8%(19/495) vs. 5.0%(24/482), P=0.385) were similar between the two groups. The incidence of 2-year MACCE (3.3%(15/453 vs. 2.4%(11/453), P=0.426) and ischemia-driven target vessel revascularization (4.2% (19/453) vs. 4.9%(22/453), P=0.632) were also similar between the two groups after matching propensity score. Conclusion The long-term clinical outcomes after early delayed PCI using DES is statistically equivalent to those of late delayed PCI using DES for STEMI patients who missed the time window for emergency PCI.

Objective To detect the expression of Beclin1 and Bcl2 in invasive pituitary adenomas and to explore the relationship of Beclin1 and Bci2 in invasive pituitary adenomas and the relativity between the 2 genes.Methods 61 specimens were classified into invasive group (32 cases) and non-invasive group (29 cases) according to the comprehensive evaluation of invasive pituitary adenomas.lmmunofluorescence analysis and RT-PCR were adopted respectively to detect the protein and mRNA expressions of Beclinl and Bcl2.The difference and relativity of Beclin1 and Bcl2 expression in invasive group and non-invasive group were analyzed.Results 32 specimens of pituitary adenoma were invasive and 29 were non-invasive.Beclin1 protein and mRNA expressions were lower in the invasive group than in the non-invasive group (P ＜0.01 ).Bcl2 protein and mRNA expressions were higher in the invasive group than in the non-invasive group (P ＜0.01 ).Pearson related analysis showed that Beclin1 mRNA expression was negtively correlated with Bcl2 mRNA expression in the invasive group ( r =-0.42,P =0.028 ).Conclusions Beclinl expression is decreased in invasive pituitary adenomas.The invasiveness of pituitary adenoma is closely related to the high expression of Bcl2 protein and mRNA,and the low expression of Beclin1 protein and mRNA.The inhibition of the autophagy may lead to the enhancement of the invasiveness of pituitary adenomas and that inhibition may come from the interaction of Beclin1 and Bcl2.

ObjectiveTo compare the therapeutic effects of percutaneous cervical discectomy (PCD group),percutaneous cervical disc nucleoplasty(PCN) and the association of them (PCDN) for the treatment of cervical intervertebral disk displacement and instability of cervical vertebral column.Methods From February 2003 to April 2011,171 consecutive patients with cervical disc herniation have presented at the authors' hospital and were retrospectively studied.The average age of patients was 47.8 years(ranged,21-74).Ninety-seven cases were treated with PCD,50 cases with PCN,and the other 24 cases with PCDN.Clinical result and the stability of cervical vertebral column after operation were evaluated and compared among the 3 groups.ResultsAll cases had been followed up for a median of 4.1 years.There was significant difference in the pre- and post-operation the Japanese Orthopaedic Association(JOA) scoring system on within 3groups (PCD:t=21.85,P＜0.05; PCN:t=14.50,P＜0.05; PCDN:t=8.56,P＜0.05).All cases had been successfully operated.There was no significant difference between groups among the 3 groups in terms of the clinical outcomes(The recovery rate of JOA standard evaluation,F=2.19,P=0.12).According to Odom criteria,the excellent and good rate are as follows:81.35％ in PCD,82.44％ in PCN,83.19％ in PCDN,respectively.There was no significant difference between groups among the 3 groups in terms of the clinical success rate (P＞0.05).There was no instability of cervical vertebral column cases in 3 groups after operation(P＞0.05),and no significant difference was found in terms of cervical vertebral column stability in pre- and post-operation in each group.ConclusionAll the three operations including PCN,PCD and PCDN are safe,minimally invasive spine surgery for the treatment of cervical intervertebral disk displacement; they achieve good clinical outcomes and there are no difference on the stability of cervical vertebral column between preoperation and postoperation.

Objective To summarize the initial experience in application of mesohepatectomy for the treatment of central liver tumors while focusing on its indication, short-term and long-term prognosis and especially outlining its technical details. Methods The clinical data of 3 patients receiving mesohepatectomy from December 2007 to March 2009 in our hospital were retrospectively analyzed.The imaging characteristics were summarized to convey the indication details. The technique details of the operation were outlined so as to reduce blood loss or other complications during and after the operation. The post-operative course and follow-up data were also collected and analyzed. Results Two patients suffered from primary hepatocellular carcinoma with liver cirrhosis and the other from giant hemangioma. The tumors were located in Couinaud yegment Ⅳ and/or Ⅷ. The average blood loss and operative duration were 800 ml and 7 h, respectively. Blood liver function tests returned to normal within 7 days postoperatively and the patients were discharged after that. No complications occurred. The follow-up for 7-15 months showed that there was no recurrence. Conclusion Mesohepatectomy is the principal choice of treatment for centrally located liver tumors. For the safety and avoidance of complications, the doctor should abide by the concept of segment-oriented hepatectomy and apply the updated techniques such as CUSA (Cavitron ultrasonic surgical aspirator). For patients with compromised liver function, mesohepatectomy might be superior to extended bepatectomy. Thus, the application of mesohepatectomy should be expanded. Meanwhile, further investigation is needed for its full evaluation.

Objective To summarize the experience in the diagnosis and treatment of elastofibroma dorsi,focusing on the clinical features,the specific radiological characteristics,and the typical pathological alterations.Methods Clinical data of 10 cases of pathologically confirmed elastofibroma dorsi from January 1997 to April 2008 were retrospectively reviewed.Results Most patients were female(8/10)in this series.All the lesions were located within the muscles in the subscapular region.There were 13 lesions in 10 cases(3 cases with bilateral involvement).Seven patients complained of pain and feeling of foreign body,and three were asymptomatic.The size of the masses was between 4 centimeters to 12 centimeters,averaging at(7.46 ±2.70)centimeters.Except for the early 3 cases,accurate diagnosis was made in all the other 7 cases before the histological exams solely based on the physical examination and imaging findings.Marginal excision was done for all the cases under general anesthesia.Fluid accumulation,as the only kind of complication was found in 3 cases which was resolved by repeated paracentesis.No recurrence was found during the follow-up period(4 months to 125 months,median 11 months).Conclusion Elastofibroma dorsi is a rare,pseudotumoral lesion usually found in elderly women.It is a very special type of soft tissue tumors that its diagnosis can usually be made solely on the basis of unique imaging characteristics and physical examination before the histological exam.Surgical marginal excision is the choice of treatment with good short-term and long-term results.

Objective To evaluate the effects of different selection criteria on the prognosis of hepatocellular carcinoma(HCC)patients undergoing liver transplantation(LT)and to evaluate a new criterion.Methods A retrospective analysis was performed on 81 consecutive patients with HCC who underwent LT.The survival rates of the patients who met different criteria such as Milan.UCSF(University of California San Francisco UCSF).and Pittsburgh(Pitt)modified TNM criteria were calculated by KaplanMeier method,and the value of different criteria was evaluated.The Long-Rank test and COX proportional hazards regression model were performed to analyze the prognostic factors.the model of criteria was established according the most important prognostic factors.Using the Kaplan-Meier method,the suitable cut-offs of every variable ifl the model were found by comparing the survival and the number of the patients who met the cut-off,and considering the significant difference between the patients who met and exceed the cut-off at the same time.Resuits The 1,2,3-year accumulative survival rates of the 19 patients who met Milan criteria were 87.7%,87.7%,and 52.6%respectively:the 1,2,3-year disease free survival rates of them were 88.9%,72.7%,and 72.7%respectively.The 1,2.3-year accumulative survival rates of the 26 patients who met UCSF criteria were 87.2%,80.5%,and 55.2%respectively;the 1,2,3-year disease free survival rates of them were 84.1%,68.4%,and 68.4%respectively.With our new expanded criterion as of solitary tumor≤8 cm in diameter.or no more than 3 tumors,with the largest≤6 am,and a total tumor diameter≤10 cm.there was no significant difierence in 1,2,3-year sunrival rates and disease free survival rates(89.0%,81.8%,71.8%,and 81.9%,72.4%,72.4%.)as compared with Milan or UCSF criteria.but with this new criterion more patients(a=41)would be eligible for transplantation with a comparable long term survival.and the difference of the accumulative survival rates and disease free survival rates of the patients who met and exceed the new criteria was significant(P＜0.05).Conclusion The new indication is acceptable because the criteria does not adversely impact survival.
