Schizophyllum commune has emerged as the most promising model mushroom to study developmental stages (mycelium, primordium), which are two primary processes of fruit body development. Long non-coding RNA (lncRNA) has been proved to participate in fruit development and sex differentiation in fungi. However, potential lncRNAs have not been identified in S. commune from mycelium to primordium developmental stages. In this study, lncRNA-seq was performed in S. commune and 61.56 Gb clean data were generated from mycelium and primordium developmental stages. Furthermore, 191 lncRNAs had been obtained and a total of 49 lncRNAs were classified as differently expressed lncRNAs.Additionally, 26 up-regulated differently expressed lncRNAs and 23 down-regulated between mycelium and primordia libraries were detected. Further, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that differentially expressed lncRNAs target genes from the MAPK pathway, phosphatidylinositol signal, ubiquitin-mediated proteolysis, autophagy, and cell cycle. This study provides a new resource for further research on the relationship between lncRNA and two developmental stages (mycelium, primordium) in S. commune

Objective:To analyze the value of C-reactive protein to prealbumin ratio (CRP/PA) combined with neutrophil CD64 (nCD64) index in evaluating the severity and prognosis of mycoplasma pneumonia (MPP) in children.Methods:The clinical data of 98 children with MPP admitted to Changzhou Maternal and Child Health Hospital from March to December 2023 were retrospectively analyzed. According to the severity of the patients, they were divided into mild children (60 cases) and severe children (38 cases). After 7 days of routine treatment, the patients were divided into good prognosis group (72 cases) and poor prognosis group (26 cases). The CRP/PA and nCD64 indices of children with different severity of disease were compared, and the relationship between CRP/PA and severity of disease was analyzed. The clinical data of children with different prognosis outcomes were compared, and the influencing factors of prognosis were analyzed. The area under receiver operating characteristic (ROC) curve (AUC) was used to analyze the prognostic value of CRP/PA and nCD64 index.Results:CRP/PA[(1.05±0.21) vs (0.77±0.15)] and nCD64 index [(4.11±0.82) vs (2.96±0.59)] in severe children were higher than those in mild children (all P<0.05). Pearson analysis showed that CRP/PA and nCD64 index were positively correlated with clinical pulmonary infection score (CPIS) ( r=0.587, 0.574, all P<0.05). Univariate analysis showed that the age of the poor prognosis group [(4.81±0.96)years vs (6.67±1.33)years] was smaller than that of the good prognosis group. The severity of the disease was severe [65.38%(17/26) vs 29.17%(21/72)], complicated complications [46.15%(12/26) vs 18.06%(13/72)], CRP/PA[(1.23±0.25) vs (0.74±0.15)] and nCD64 index [(4.48±0.89) vs (3.02±0.61)] were higher than those in good prognosis group (all P<0.05). Binary logistic regression analysis showed that the severity of disease ( OR=4.251, 95% CI: 1.682-10.742), CRP/PA ( OR=3.857, 95% CI: 1.886-7.887), nCD64 index ( OR=3.161, 95% CI: 1.382-7.228) were prognostic factors (all P<0.05). ROC curve showed that the sensitivity and specificity of CRP/PA, nCD64 index and their combination in predicting prognosis were 76.90%, 73.10% and 88.50%, respectively, and 73.60%, 72.20% and 90.30%, respectively. The AUC values were 0.809, 0.794 and 0.923 (all P<0.001). Conclusions:CRP/PA and nCD64 index are significantly positively correlated with the severity of MPP in children, and they are the influencing factors for the prognosis of children. The combined detection of CRP/PA and nCD64 index has good predictive value for the prognosis of children.

Objective To test the effectiveness of an integrated intervention to improve control and management of type 2 diabetic patients.Methods The study was designed as a randomized and multi-center clinic trial for 24 weeks.150 overweight patients from 2 companies and one hospital in Shanghai were recruited.The principal objective of the project was to compare the effectiveness of a structured diabetes management program consisting of 200 kcal breakfast as a meal replacement with low glycemic index (GI),scheduled blood glucose monitoring(6 times per week),low GI diet consulting,monitoring and medical check up and nutritional education (diet consulting,health education on nutrition and healthy lifestyle) in overweight individuals with type 2 diabetes.Results At 12th week,the level of fasting blood glucose(FBG) in both groups decreased by 16.5% and 10.6%,and at 24th week,the FBG also decreased by 25.0% in intervention group,but in control group FGB increased 2.8% (P＜0.01).Meanwhile,there were 8.2% and 11.1% reductions in HbA1C respectively at 12th week and at 24th week in intervention group,while the values were increased slightly in control group(P＜0.01).Compared with control group,waist circumference,hip circumference,and blood pressure were significantly reduced after treatment for 24 weeks in intervention group (P＜0.01).Conclusions Integrated intervention is an effective approach in managing FBG,HbA1C blood pressure,and weight control in overweight diabetic patients.

Objective To evaluate the changes in the expression of c-fos protein in the spinal cord in a rat model of oxycodone dependence or withdrawal response.Methods Thirty SPF adult male Sprague-Dawley rats,aged 6-8 weeks,weighing 180-220 g,were divided into 3 groups (n=10 each) using a random number table method:normal saline group (group NS),oxycodone dependence group (group OD),and oxycodone withdrawal group (group OW).In OD and OW groups,oxycodone was injected subcutaneously in back,5 days in total,with the dose of 2,3,4,5 and 6 mg/kg in turn,3 times a day (8:00/15:00/22:00).The equal volume of normal saline was given instead in group NS.The mechanical paw withdrawal threshold was measured at 3 days before administration and 30 min after the last administration every day.The oxycodone withdrawal was induced by intraperitoneal injection of naloxone 4 mg/kg at 8 h after the last administration of oxycodone on 5th day in group OW.The withdrawal response scores and range of weight changes were recorded within 15 min after giving naloxone or normal saline in NS and OW groups.Spinal cord tissues were collected at 1 h after the last administration on 5th day in group OD and at 1 h after giving normal saline or naloxone on 5th day in NS and OW groups for determination of the expression of c-fos protein by Western blot.Results Compared with group NS,the mechanical paw withdrawal threshold was significantly increased on 1 and 2 days after administration,and the expression of c-fos protein in the spinal cord was up-regulated in OD and OW groups,and withdrawal response scores were significantly increased,and the range of weight change was increased in group OW (P＜0.05).The expression of c-fos protein was significantly down-regulated in group OW as compared with group OD (P＜0.05).Conclusion Oxycodone dependence or withdrawal response may be related to the expression of c-fos protein in the spinal cord of rats,and the expression is up-regulated during oxycodone dependence,while down-regulated during oxycodone withdrawal.

Objective:To study the clinical manifestations, diagnosis and treatment of primary hyperparathyroidism (PHPT) in pregnancy.Methods:This study involved six pregnant patients with PHPT who were admitted to Ruijin Hospital of Shanghai Jiao Tong University from August 2014 to November 2019. Their clinical manifestations, treatment strategies (multidisciplinary consultation with departments including Obstetrics, Endocrinology, Neonatology, General Surgery, Anesthesiology and Intensive Care Unit), maternal complications and maternal and infant outcomes were described and retrospectively analyzed.Results:(1) The median age of the six patients was 34(23-38) years old. PHPT was diagnosed in one case before pregnancy, four in the second or third trimester and one after delivery. The main clinical manifestations of four cases were nausea, vomiting, anorexia and other non-specific symptoms. Anemia was the most common maternal complication (five cases). Other complications included hypercalcemia crisis with renal failure (one case), multiple bone destruction and osteoporosis (one case). The median levels of serum calcium, parathyroid hormone and 25-hydroxyvitamin D were 3.08 (2.84-4.21) mmol/L, 216.7(93.1-2 603.6) ng/L and 29.66 (13.50-90.24) nmol/L, respectively. Results of parathyroid ultrasonography showed all patients had hypoechoic focus. Four cases underwent routine parathyroid radionuclide imaging showing abnormal radioactive concentration areas. (2) Obstetricians initiated the multidisciplinary team (MDT) for all patients to determine the treatment plans after communication with the patients and their families. One case received surgical treatment five months after delivery. Three cases received surgical treatment in the second trimester and among them, one terminated the pregnancy in the second trimester and the other two continued and achieved good pregnancy outcomes. Two cases underwent surgical treatment after giving up pregnancy and induced abortion. Postoperative pathology revealed that five cases were isolated parathyroid adenoma and one was parathyroid carcinoma. All of the patients were followed up and no abnormal serum calcium was reported. (3) One newborn had hypocalcemic convulsions one month after birth and was recovered by intravenous calcium supplementation. The newborn was followed up and the serum calcium level was normal so far. The other two neonates had normal serum calcium during follow-ups, but one of them was diagnosed with autism at the age of four and is now undergoing rehabilitation treatment.Conclusions:Pregnancy complicated by PHPT may lead to serious maternal and infant complications. MDT consultation ensures timely diagnosis, comprehensive treatment for the patients and better pregnancy outcomes.

Objective: To explore the role of targeted ultrasound contrast agent in the evaluation of angiogenesis in papillary thyroid carcinoma (PTC) in nude mice by constructing platelet derived growth factor receptor α (PDGFRα)-targeted ultrasound contrast agents, and to explore the effect of platelet derived growth factor (PDGF) on angiogenesis in PTC. Methods: PDGFRα-targeted ultrasound contrast agents were constructed through biotin-avidin linkage, and blank micro-bubbles were served as control group. After the siRNA-PDGF BCPAP cell line was established, well prepared BCPAP cells or siRNA-PDGF-BCPAP cells were injected subcutaneously into the back of male BABL/C nude mice. The growth of the tumors was observed closely. All tumors of the normal group and the siRNA-PDGF group were examined by PDGFRα-targeted ultrasound contrast agents or blank micro-bubbles, and the dynamic images were analyzed quantitatively by QontraXt software.All mice were sacrificed after ultrasonography. Microvessels density (MVD) in the tumors was counted by CD31 staining and the expressions of vascular endothelial growth factor(VEGF) and PDGF were detected by Western Blot. Results: PTCs in nude mice were enhanced well by PDGFRα-targeted ultrasound contrast agent or blank micro-bubbles. The peak of tumors in siRNA-PDGF group was significantly lower than that in the normal group [(43.085±13.244)% vs (57.428±10.952)%, P=0.004]; MVD of the siRNA-PDGF group was significantly less than that of the normal group [(23.200±6.017)strips/view vs (35.000±8.456)strips/view, P=0.012]. The protein expression of PDGF and VEGF in siRNA-PDGF group were significantly lower than those in the normal group, respectively (0.142±0.058 vs 0.269±0.102, P=0.002; 0.096±0.036 vs 0.158±0.072, P=0.016). Conclusions PDGF plays an important role in angiogenesis of PTC, it maybe a new ultrasound molecular imaging method for monitoring tumor angiogenesis.

Objective:To observe the efficacy and safety of single-port laparoscopy for giant ovariotubal cysts.Methods:38 patients with giant ovarian and fallopian tube cysts in Ruijin Hospital Affiliated to Shanghai Jiaotong University Hospital from January 2018 to June 2019 were retrospectively analyzed. They were divided into transumbilical single-port laparoscopy group (18 cases) and traditional laparoscopy group (20 cases). The perioperative related indexes such as operation time, intraoperative bleeding and the number of analgesic cases were compared between the two groups.Results:All 38 patients successfully completed the operation without conversion to laparotomy, and no auxiliary hole was added in the single-port laparoscopy group; There were no postoperative complications and no cystic fluid leakage. In the single-port laparoscopy group, 18 patients were satisfied with the concealment of umbilical scar. There was no statistically significant difference in operation time [(51.67±13.72)min vs (55.50±14.59)min], intraoperative blood loss [(52.22±24.38)ml vs (61.50±28.88)ml] and first postoperative anal exhaust time [(25.77±8.59)h vs (27.60±6.67)h] between single-port laparoscopy group and traditional laparoscopy group (all P>0.05); The number of cases requiring postoperative analgesia in the single-port laparoscopy group (2 cases vs 12 cases) was less than that in the traditional laparoscopy group ( P<0.05); The out of bed activity time [(20.95±3.65)h vs (26.95±5.43)h] and postoperative discharge time [(3.11±0.68)h vs (4.30±1.21)h] were shorter than those in the traditional laparoscopy group (all P<0.05). All 38 patients were followed up in the gynecological clinic for 6-24 months. The incision healed well without recurrence. Conclusions:Transumbilical single-port laparoscopic surgery for giant ovarian and fallopian tube cysts is reliable and safe when the possibility of malignant ovarian and fallopian tube tumors was excluded before operation.

Single-cell or low-input multi-omics techniques have revolutionized the study of pre-implantation embryo development.However,the single-cell or low-input proteomic research in this field is rela-tively underdeveloped because of the higher threshold of the starting material for mammalian embryo samples and the lack of hypersensitive proteome technology.In this study,a comprehensive solution of ultrasensitive proteome technology(CS-UPT)was developed for single-cell or low-input mouse oocyte/embryo samples.The deep coverage and high-throughput routes significantly reduced the starting material and were selected by investigators based on their demands.Using the deep coverage route,we provided the first large-scale snapshot of the very early stage of mouse maternal-to-zygotic transition,including almost 5,500 protein groups from 20 mouse oocytes or zygotes for each sample.Moreover,significant protein regulatory networks centered on transcription factors and kinases between the MII oocyte and 1-cell embryo provided rich insights into minor zygotic genome activation.
