Pituitary adenoma, a benign intracranial tumor, is the third most common brain tumor, second only to glioma and me-ningioma. Pituitary adenoma has been defined as a benign tumor, but some pituitary adenomas can invade the surrounding tissue. This tumor is difficult to resect and can easily recur after surgery. RWD-containing sumoylation enhancer (RSUME) can stabilize the activity of hypoxia-inducible factor-1α and inhibitor kappaB by the small ubiquitin-related modifiers. This phenomenon indicates the impor-tance of RSUME in pituitary adenoma because it promotes the invasiveness of the tumor. However, the correlation between RSUME and the invasion of pituitary adenoma remains unclear. In this study, the roles of RSUME on HIF-1α/VEGF signaling pathway and IκB/NF-κB compomers in the invasiveness of pituitary adenoma were reviewed.

Objective To observe the clinical efficacy of electroacupuncture plus nasal irrigation in treating upper airway cough syndrome (UACS).Method A total of 114 UACS patients were randomized into 3 groups, 38 cases in each group. Group A was treated with acupuncture plus electrical stimulation with sparse-dense wave, group B was intervened by nasal irrigation with Shuang Huang Lian, and group C was treated with the two methods together. The clinical efficacies of the three groups were compared.Result The total effective rates were respectively 84.2%, 73.7% and 94.7% in group A, group B and group C. The total effective rate of group C was significantly different from that of group A and group B (P<0.05).Conclusion Electroacupuncture plus nasal irrigation can produce a more significant therapeutic efficacy compared to electroacupuncture or nasal irrigation alone.

Objective To investigate the role of Kit signal pathway in the proliferation and spontaneous rhythmic motility of interstitial cells(ICs)in the bladder of guinea pigs.Methods Fourteen Guinea pigs aged 45-60 days were administered with Imatinib intragastrically for 20 and 40 days.Three were fed on normal saline as control.The morph and number of ICs were observed by immunofluorescence,Kit protein expression was detected by Western blot and spontaneous rhythmic motility of bladder were investigated in in vitro organ bath.Results Quite a few ICs were observed in the bladder of controls.After administration of Imatinib,the amount of ICs and the expression of Kit protein decreased gradually,and the spontaneous rhythmic contraction weakened.Conclusion ICs might be the pacemaker of bladder in guinea pigs.Kit protein might play an important role in the survival and functional maintenance of ICs.

Objective To evaluate a protocol of early treatment for dogs suffering from open abdominal injury and seawater immersion. Methods A canine model of open abdominal injury was made with 30 adult health dogs. After 2 hours seawater immersion, the dogs were divided into two groups: treatment group( n =18) and control group(untreated group, n =18). The changes of survival rate, body liquid metabolism and hemodynamics were observed respectively. Results The survival rate significantly increased from 0 in control group to 94 4% in treatment group. The disorder of hemodynamics and body liquid metabolism was improved significantly, P

Objective To evaluate the outcome of primary total knee arthroplasty (TKA) in treatment of stiff knee, and discuss the key points of operative technique and rehabilitation. Methods From February 2005 to April 2009, 23 patients with 34 stiff knees were treated with primary TKA. The study included 3 males (4 knees) and 20 females (30 knees), with the mean age of 56.9 years. Primary disease of the patients included rheumatoid arthritis (26 knees in 15 cases) and osteoarthritis (8 knees in 8 cases). Varus deformity was found in 10 knees (5°-15°), and valgus was found in 5 knees (5°-10°). Evaluations included preoperative and postoperative range of motion (ROM) measurement, hospital for special surgery knee score (HSS), blood loss, operative time and assessment of postoperative complications. Results All patients were followed up. The mean follow-up time was 32.2 (range, 24 to 40) months. At the final follow-up visit, the HSS score increased from 42.9±5.2 preoperatively to 85.7±4.3, the range of motion increased from 42.6°±5.7° preoperatively to 89.2°±10.5°. Sixteen knees in 12 cases underwent manipulation at 3 to 8 weeks postoperatively for unsatisfied ROM, but ROM was still less than 90° in 8 knees at the last follow-up. The average blood loss were (632.4±180.2) ml in first 24 hours (450-850 ml) and the operative time were (98.1±18.6) min (80-150 min). Deep venous thrombosis was found in 3 patients. All the symptoms relieved after anticoagulant therapy. Postoperative varus deformity was seen in one patient, but the function of knee was good. No revision was needed. Conclusion Primary total knee arthroplasty is reliable method in treatment of stiff knees. Sufficient soft tissue release during the operation, postoperative muscle strength exercise and essential manipulation are key points for satisfactory outcomes.

Objective· To investigate the prospective value of early postoperative PI-APD in children with hydronephrosis.Methods· Data of children with hydronephrosis who underwent pyeloplasty in Xinhua Hospital,Shanghai Jiao Tong University School of Medicine between Jan 2012 to Nov 2015 was collected.PI-APD was divided into 3 categories (≤ 19％,19％＜PI-APD＜40％ and ≥ 40％).The relationship between PI-APD value and the degree of renal function (DRF) and dilation recovery after surgery was analyzed.Results· There were 360 children with hydronephrosis.The median follow-up was 20 months.The PI-APD value (3 months after pyeloplasty) was positively correlated with the degree of DRF recovery (r=0.631,P=0.000).Five patients received redo-pyeloplasty.PI-APD of all these patients was ＜19％.Conclusion· PI-APD is a new feasible ultrasound parameter in pyeloplasty followup.PI-APD ≥ 40％ at the first post-operative visit predicts pyeloplasty success.PI-APD ≤ 19％ indicates close follow-up after operation.PI-APD can also help select children at high risk for repeat intervention after pyeloplasty.

Objective:To explore the effect of postoperative stent placement time on flexible ureteroscopy lithotripsy (FURL) in the treatment of kidney calculi.Methods:A retrospective analysis of 126 patients with kidney calculi admitted to Guangyuan Central Hospital from April 2017 to November 2018. All patients were treated with FURL. The patients were divided into two groups according to the time of stent placement after FURL: conventional tube placement group ( n=91) and short-term tube placement group ( n=35). The postoperative stent placement time of patients in the conventional tube placement group was 4 weeks, and the postoperative stent placement time of patients in the short-term tube placement group was 2 weeks. The postoperative outcome indicators (hospitalization time and stone-free rate), postoperative complication indicators (postoperative hematuria, renal hematoma, urinary tract infection and fever) and postoperative pain were compared between the two groups. The measurement data was expressed as mean±standard deviation ( Mean± SD), and the Student′s t test was used for comparison between groups; the Chi-square test was used for comparison between counting data. Results:There were not significant differences in hospitalization time [(7.22±1.02) d vs (7.26±1.22) d], stone-free rate 1 month after surgery (84.6% vs 82.8%), stone-free rate 2 month after surgery (93.4% vs 88.5%), postoperative hematuria (10.9% vs 11.4%), renal hematoma (3.3% vs 0) and fever (2.2% vs 0) between the conventional tube placement group and short-term tube placement group ( P>0.05). Compared with the conventional tube placement group, the short-term tube group had lower urinary tract infection rates (17.6% vs 2.9%), the difference was statistically significant ( P<0.05). There was not significant difference in the average use rate of opioids [(1.05±0.45) vs (1.00±0.50), P>0.05], acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) [(1.52±0.55) vs (1.45±0.45), P>0.05] between the two groups during hospitalization. There was not statistically significant difference in the incidence of abdominal pain after discharge from the hospital [(1.25±0.55) vs (1.15±0.45)]. The number of applications of acetaminophen and NSAIDs in the conventional tube placement group was greater than that in the short-term tube placement group [(1.45±0.46) vs (1.25±0.30)] after one month, the difference was statistically significant ( P<0.05). Conclusions:Short-term tube placement after renal FURL surgery is as effective as traditional long-term stenting, achieving the same stone-free effect and reducing early postoperative complications. For the reduction of postoperative infection and postoperative pain, short-term stenting has certain advantages.

Estrogen-related receptor alpha (ERR alpha) is an orphan nuclear receptor and functions as a key regulator of energy metabolism in high energy demand tissues. However, its role in white adipose tissue is largely unknown. In this study, we aim to clone the ORF sequence of pig ERR alpha with touch down-PCR, analyze the expression pattern of ERR alpha protein and its subcellular localization with Western blotting and cell immunofluorescence method respectively, and identify the effect of ERR alpha on lipid accumulation in mature porcine adipocytes with its specific inhibitor XCT790. The results showed that the ERR alpha ORF sequence is 1269 bp (GenBank Accession No. FJ446485, not published), and encode 422 amino acids. The homologies of ERR alpha nucleotide and amino acids sequences are high in different species. ERR alpha protein is highly expressed in pig white adipose tissue, kidney and heart, while remarkably lower in spleen. Cell immunofluorescence results indicated that ERR alpha protein distribute widely in adipocytes nucleus and cytoplasm. XCT790 significantly inhibited the expression of ERR alpha and lipid accumulation in porcine mature adipocyte. This study will provide new target and theoretical reference for fat deposition control.

Objective Using gradient-echo sampling of spin-echo (GESSE) sequence to study the change of oxygen extraction fraction (OEF) in patients with unilateral cerebral vessel stenosis and the relationship between OEF and cerebral blood flow (CBF). Methods Eight normal volunteers and 16 patients with unilateral cerebral vessel stenosis were enrolled in this study. Written informed consents were obtained from all subjects. Routine MRI, GESSE and arterial spin labeling (ASL) sequences were performed for all patients. Raw data from GESSE and VE-ASL sequences were transferred to PC to conduct postprocessing. To obtain quantitative OEF and CBF of the brain parenchyma, 6 ROIs were placed respectively in the anterior, middle and posterior part of both hemispheres. The relative CBF (rCBF) was defined as the ratio of CBF of ischemic hemisphere to that of contralateral hemisphere. T test was used for statistics. Results The mean value and normal range of OEF in the volunteers were 0. 318 ± 0. 023 and 0. 272-0. 364, respectively. In the 16 patients with unilateral cerebral vessel stenosis, 8 patients had ROIs with greater OEF in unilateral hemisphere than those in contralateral hemisphere. These cases presented multiple intracranial main arterial stenoses in digital subtraction angiography (DSA) or MR angiography (MRA) examination. The other 8 patients had normal OEF in all ROIs. And they only had single arterial stenosis in DSA or MRA. Set rCBF = 0. 50 as a dividing point, the mean OEF value was 0. 397 ±0. 010 in the patients with rCBF ＜ 0. 50. In the patients with rCBF ≥ 0. 5, the mean OEF value was 0. 325 ±0. 028. The difference between the two groups was statistically significant (t = - 8. 840, P = 0. 000).Conclusion Patients with chronic cerebral ischemia may present with various hemodynamic impairment.The more CBF decreases, the more OEF increases. Those with increased OEF tended to have more than one lesion in the major intracranial arteries.
