This study examined the sodium nitroprusside (SNP) toxicity to central nervous system (CNS) in treatment of patients with aortic dissection (AD). The medical records of 191 AD patients who were admitted to Tongji Hospital, China, from Jan. 1998 to Feb. 2009 were retrospectively analyzed. There were 140 cases of hypertension (73.3%) and 13 cases of Marfan syndrome (6.8%) among the 191 AD patients. A total of 157 patients were given SNP treatment. The toxic reactions of CNS occurred in 18 subjects (11.5%). Most of the adverse reactions occurred on the fifth day following SNP injection. SNP infusion rate was significantly higher in patients who developed CNS toxicity. It was suggested that systemic hypertension is the most common predisposing factor for AD. The combination of SNP with a β-receptor blocker is a medical therapy commonly used in patients with AD. Cyanide and thiocyanate toxicity from SNP treatment is always the consequence of prolonged drug infusion or relatively high dose administration.

To obtain the recombinant tumor necrosis factor-α converting enzyme (TACE) ectodomain and use it as a selective molecule for the screening of TACE peptide inhibitors, the cDNA coding catalytic domain (T800) and full-length ectodomain (T1300) of TACE were amplified by RTPCR, and the expression plasmids were constructed by inserting T800 and T1300 into plasmid pET28a and pET-28c respectively. The recombinant T800 and T1300 were induced by IPTG, and SDSPAGE and Western blotting analysis results revealed that T800 and T1300 were highly expressed in the form of inclusion body. After Ni2+-NTA resin affinity chromatography, the recombinant proteins were used in the screening of TACE-binding peptides from phage display peptide library respectively. After 4 rounds of biopanning, the positive phage clones were analyzed by ELISA, competitive inhibition assay and DNA sequencing. A common amino acid sequence (TRWLVYFSRPYLVAT) was found and synthesized. The synthetic peptide could inhibit the TNF-α release from LPS-stimulated human peripheral blood mononuclear cells (PBMC) up to 60.3 %. FACS analysis revealed that the peptide mediated the accumulation of TNF-α on the cell surface. These results demonstrate that the TACE-binding peptide is an effective antagonist of TACE.

Objective:
To explore the influence of personalized normative feedback interventions on precaution of adolescents’ Internet addiction,and to provide a new perspective for intervention in youth health online.
Methods:
A total of 170 students from the second grade in a middle school and a high school of Fuzhou Province were randomly selected between April and May in 2016. By using the pretest post-test control group design, 90 adolescents in experimental group received personalized normative feedback interventions, while the 80 adolescents in control group were tested without interventions.
Results:
At 1-month after intervention, students in the intervention group showed positive results relative to those in the control group on variables associated with online behavior, including the online time of students in experimental group and the index of their internet addiction have significantly reduced(t=2.79 and 3.09, P<0.01). Simultaneously, the estimate of the online time towards the experimental group students has decreased(t=3.75 and 3.74, P<0.01), the estimate of the proportion of study uses has decreased(t=-2.56, P<0.05).
Conclusion
The personalized normative feedback interventions, to some extent, has some precautions on the adolescents’ behaviors of internet addiction.

Background Patients often suffer from a few complications of neurological and psychiatric problems after traumatic brain injury including damage of cognition, mental disorders and behavior problems. Damage of cognition is a common sequela in traumatic brain injury. Numerous researchers were focus on the cognition changes of patients with mild brain injury. But their conclusions are debatable. Executive function is one of the important components of cognition. In this study,we tried to find out the executive functional alterations of the patients with mild brain injury.Methods 159 patients with brain injury caused by transportation events and 68 normal controls were assessed executive function. The executive function tests included the block design in WAIS, the Stroop test, the verbal fluency and the modified version of Wisconsin card sorting test (M-WCST). These tests were applied to compare the scores of traumatic brain injury patients with various severities including mild, moderate, and severe and with different CT/MRI results.Results Patients with mild head injury got significantly lower scores on all tests than normal controls ( P<0.01 ). But there was no significant difference between mild and moderate brain injury group. Except Stroop test and WCST categories, patients with mild brain injury got significantly lower scores on all other tests than those with severe brain injury ( P <0.05). In the brain injury cases with damage signs on CT/MRI, there was no significant difference on scores of all tests except block design tests among brain injury patients with various severities. Among the brain injury cases without any damage signs on CT/MRI, there was no significant difference on scores of all tests among brain injury patients with various severities. The correlation analysis showed that scores of block design and verbal fluency test were negatively related to the severity of brain injury( P<0.05). The age and the education level of the patients had negative and positive correlation, respectively, to executive function.Conclusions The executive function of patients with mild brain injury was impaired when the medication was terminated. We should pay more attention to patients with mild brain injury by performing various tests for assessment of disability.

Objective To investigate the relationship between serum progesterone level at the day with human chorionic gonadotrophin (hCG) administration and pregnant outcome from in in-vitro fertilization-embryo transfer(IVF-ET). Methods From Mar. 2002 to Apr. 2007, 786 cycles with serum progesterone measurement on the day of hCG administration for final oocyte maturation in IVF were analyzed retrospectively in Reproductive Medicine Center in First Affiliated Hospital of Nanjing Medical University.All stimulations were down-regulated with gronadotrophin release hormone agonist (GnRH-a) in both long protocols and short protocols before gonadotrophin stimulation. When the thresholds of serum progesterone were set at 5.5, 6.0,6.5,7.0,7.5,8.0,8.5 and 9.0 nmol/L, respectively. If the level of progesterone was less than the thresholds, those patients were in lower progesterone group, on the contrary, more than the threshold value, those patients were in higher progesterone group. The laboratory results and the clinical outcomes between all patients at lower and higher progesterone group at different thresholds value were analyzed. Results The rate of normal fertilization, quality embryos, successful implantation, chemical pregnancy, clinical pregnancy and live birth did not exhibit remarkable difference between patients with higher and lower serum progesterone level at multiple thresholds on the day of hCG administration in the 786 cycles (P >0.05). However, when the thresholds of serum progesterone were at 8.5 and 9.0 nmol/L, early abortion rates of 27.3% (3/11) and 3/7 in higher progesterone group were significantly higher than 8.8% (26/297) and 8.6% (26/301) in lower progesterone group (P<0.05). And the total abortion rates of 3/7 in higher progesterone group were significantly higher than 11.0% (34/301) in lower progesterone group when the thresholds of serum progesterone were 9.0 nmol/L (P<0.05). Conclusions This study did not prove the correlationship between progesterone level at the clay with hCG administration and the probability of clinical pregnancy or live birth. However, early abortion rates or the total abortion rates were associated with higher progesterone level when the thresholds of serum progesterone were at 8.5 nmol/L or 9.0 nmoL/L.

Objective:To compare the clinical efficacies of O-arm combined with CT three-dimensional navigation system assisted screw placement versus manual screw placement in treating lower cervical fracture and dislocation.Methods:A retrospective cohort study was used to analyze the clinical data of 41 patients with lower cervical fracture and dislocation, who were treated in Honghui Hospital, Xi′an Jiaotong University from May 2021 to February 2022. The patients included 26 males and 15 females, aged 31.5-48.6 years [(41.5±15.0)years]. The injured segments were C 3 in 3 patients, C 4 in 12, C 5 in 13, C 6 in 10 and C 7 in 3. Nineteen patients were treated with cervical pedicle screws by O-shaped arm combined with CT three-dimensional navigation system (navigation group, 76 screws) and 22 by bare hands (traditional group, 88 screws). The total operation time, effective operation time, single nail placement time, single screw correction times, screw distance from anterior cortex, intraoperative blood loss, intraoperative fluoroscopic radiation dose, incision length and length of hospital stay were compared between the two groups, and the height of intervertebral space, Cobb angle, interbody slip distance and American Spinal injury Association (ASIA) grade were compared before operation and at 3 days after operation. Visual analogue score (VAS), Japanese Orthopedic Association (JOA) score, and neck dysfunction index (NDI) were evaluated before operation, at 3 days, 3 months after operation and at the last follow-up. Accuracy of screw placement and incidence of complications (adjacent facet joint invasion, infection, screw loosening) were detected as well. Results:All the patients were followed up for 11.1-13.9 months [(12.5±1.4)months]. The total operation time, intraoperative blood loss, intraoperative fluoroscopic radiation dose and incision length in the navigation group were more or longer than those in the traditional group (all P<0.05). The effective operation time, single nail placement time, single nail correction times and screw distance from anterior cortex in the navigation group were markedly less or smaller than those in the traditional group (all P<0.05). There was no significant difference in the length of hospital stay between the two groups ( P>0.05). There were significant improvements in the height of intervertebral space, Cobb angle and interbody slip distance between the two groups at 3 days after operation (all P<0.05). There was no significant difference in the height of intervertebral space, Cobb angle, interbody slip distance or ASIA grade between the two groups before operation or at 3 days after operation (all P>0.05). Compared with pre-operation, the VAS, JOA score and NDI were significantly improved in both groups at 3 days, 3 months after operation and at the last follow-up (all P<0.05), with further improvement with time. There was no significant difference in VAS between the two groups before operation or at 3 months after operation (all P>0.05), but it was markedly lower in the navigation group compared with the traditional group at 3 days after operation and at the last follow-up (all P<0.05). There were no significant differences in JOA score or NDI between the two groups before operation or at 3 days and 3 months after operation (all P>0.05), but both were lower in the navigation group compared with the traditional group at the last follow-up (all P<0.05). The accuracies of placement of grade 0 and grade 0+1 screws were 92.0% (70/76) and 96.6% (73/76) in the navigation group, respectively, which were markedly higher than 88.7% (78/88) and 93.5% (82/88) in the traditional group (all P<0.05). The rates of adjacent facet joint invasion of A, B, and C degrees were 71.2% (54/76), 28.8% (22/76) and 0% (0/76) in the navigation group, respectively, while the invasion rates were 60.5% (53/88), 32.3% (28/88) and 7.3% (7/88) in the traditional group ( P<0.05). No screw loosening was noted in the navigation group, but the screw loosening rate was 9.1% (8/88) in the traditional group ( P<0.01). Conclusion:Compared with manual screw placement, O-arm combined with CT three-dimensional navigation system assisted screw placement for lower cervical fracture and dislocation has the advantages of shorter effective operation time, quicker screw placement, stronger screw holding force, better cervical stability, slighter postoperative pain, higher screw placement accuracy, and lower facet joint invasion and screw loosening rates.

Objective:To investigate the efficacy and safety of promestriene vaginal gelatin capsules administered through different schemes in the treatment of postmenopausal female urethral syndrome.Methods:A total of 120 patients with postmenopausal female urethral syndrome who received treatment in General Hospital of Medical and Health Group of Cixi Third People's Hospital from January 2021 to June 2022 were included in this study. They were randomly divided into groups A and B ( n = 60/group). Group A was treated with vaginal gelatin capsules containing 10 mg promestriene once a day. Group B was treated with vaginal gelatin capsules containing 10 mg promestriene twice a day. Both groups were treated for 20 days as a course of treatment. The improvement of symptoms, lower urinary tract symptom score, quality of life score, estradiol level, follicle stimulating hormone level, and endometrial thickness were compared between the two groups. Results:After treatment, the scores of incomplete urination, urination interval, intermittent urination, dysuria, thinner urine line, urination force, and nocturnal urination times in group A were (2.51 ± 1.76) points, (2.66 ± 1.08) points, (2.61 ± 1.45) points, (2.48 ± 1.42) points, (2.85 ± 1.03) points, (2.48 ± 1.42) points, and (2.52 ± 1.72) points, respectively, which were significantly lower than (3.15 ± 1.35) points, (3.23 ± 1.14) points, (2.99 ± 1.57) points, (3.08 ± 1.09) points, (3.45 ± 1.72) points, (3.25 ± 1.08) points, and (3.21 ± 1.87) points, respectively, in group B ( t = 10.57, 9.78, 13.83, 10.34, 9.35, 12.34, 9.45, all P < 0.05). The quality of life score in group A was (2.45 ± 0.86) points, which was significantly lower than (3.51 ± 0.92) points in group B ( t = 5.45, P < 0.05). There were no significant differences in estradiol and follicle stimulating hormone levels and endometrial thickness between the two groups before and after treatment (all P > 0.05). There was no significant difference in the incidence of adverse reactions between the two groups. Conclusion:Local application of promestriene vaginal gelatin capsules can improve the urethral syndrome in postmenopausal women. The once daily 10 mg promestriene vaginal gelatin capsule administration scheme can achieve better efficacy and safety than the twice daily administration scheme. The study is innovative, scientific, and worthy of clinical promotion.
