Objective:To compare the effects of rotational night shifts on the micturition patterns of fe-male nurses.Methods:A total of 58 nurses without lower urinary tract symptoms were recruited,who worked in the Peking University People’s Hospital during January and June in 2014.The nurses aged 20 -43 years were divided into two groups,the night-shift group (n =28)and the non-shift group (n =30).The alcohol or coffee intaking were forbidden.In the night-shift group,nurses had worked on rota-tional shifts for at least 6 months.Their average age was (26.75 ±4.11)years.In the non-shift group, nurses took regular day-time work,whose average age was (27.80 ±5.60)years.A voiding diary was kept for 7 consecutive days at the end of 6 months,starting 2 days before their night duties until 4 days after completion of their night duties.For comparison,the non-shift group with regular shifts completed a 7-day voiding diary.In the 7-day recording voiding diary,the nurses were required to have the normal in-take of liquid about 1 500 -2 000 mL/d.The frequency volume charts of nocturia,the 8-hour interval urine production and frequency were compared between the two groups.Results:Nocturia frequency was increased in the night-shift group [0.5 (0 -2.4)]compared with the non-shift group [0 (0 -2),P =0.02].The volume of nocturia was increased in the night-shift group [125 mL (0 -660 mL)]compared with the non-shift group [0 mL (0 -340 mL),P <0.01].The 8-hour interval indices showed that urine production changed with shift (P <0.01).In the consecutive 7 days,the nocturnal volume of the night-shift group increased on the day after night shift.When the night-shift nurses returned to daytime duty, the volume of urine decreased but nocturnal urine production remained high,and the frequency of noctu-ria also increased significantly (P <0.05).Compared with the 8-hour interval indices,the night-shift group’s voiding volume [(542.35 ±204.66)mL]and voiding frequency (2.24 ±0.69)were more than those of the non-shift group at the afternoon time (from 2 pm to 10 pm).During the 8 h interval night time (from 10 pm to 6 am),the volume of nocturia in the night-shift group [(309.74 ±162.74) mL]was more than that in the non-shift group [(199.38 ±153.98)mL,P =0.01];the frequency of nocturia in the night-shift group (1.31 ±0.52)was increased than that in the non-shift group (0.82 ± 0.55,P <0.01).Conclusion:The rotational shifts affect the micturition patterns of nurses who go through the night shift work,which increases the volume and frequency of the nocturia.

Purpose Two kinds of forward conditional reasoning including modus ponens (MP) and denial of the antecedent (DA) are the most common deductive reasoning in daily life. The present study aimed to explore the difference between the two neural machanisms. Materials and Methods Three kinds of tasks including MP, DA, and baseline were administrated to 14 undergraduates [7 males and 7 females, mean age (23.4±1.3) years] by using functional magnetic resonance imaging (fMRI) technique. fMRI data was analyzed. Results The reaction times were significantly slower for MP and DA than that of BS (P<0.001), while the effect was not significant for accuracy. In contrast to baseline, both MP and DA tasks activated the left inferior frontal cortex (BA 9), inferior parietal lobule (BA 40), and postcentral gyrus. Bilateral caudate significant activation was found in MP task when compared with DA, whereas the frontal, parietal, occipital lobe and anterior cingulate cortex were acivated more in the DA than in MP task. Conclusion Both forward conditional reasoning of MP and DA commonly activate the left frontoparietal cortex, while significant dissociations can be seen in the regions of caudate and bilateral frontal, parietal and occipital. These results firstly demonstrates the different neural mechanism underlying the two forward conditional reasoning, which might help to further uncover the brain mechanism of conditional reasoning.

The incidence of venous thromboembolism after spinal cord injury is high, and its diagnosis and prevention received much attention in clinical research in recent years. Because of the special characteristics, the prevention of venous thrombosis should be combined with basic prevention, physical prevention and drug prevention. According to the different situations of venous thromboembolism in patients with spinal cord injury, the prevention methods need to adjust to carry out multidisciplinary comprehensive treatment.

OBJECTIVE To investigate the induc-ing factors of Bell’s palsy. METHODS From Febru-ary to May 2005, 262 outpatients of Bell’s palsy were surveyed for 9 inducing factors. RESULTS The mean age of onset was 39?17 years old. The ratio of male to female and of left to right were 48:52. Forty-eight patients denied all inducing factors, while 214 pa-tients (81.7 %) had at least one factor. Cold was found in 53.5 % of the patients, fatigue in 22.5 %, viral infec-tion in 18.7 %, recurrence in 11.8 %, psychological stress in 11.5 %, family history in 7.6 %, puerperal period in 1.5 %, and molar infection of the affected side in 1.5 %. CONCLUSION Bell’s palsy is likely to be a set of disease. Most of patients with Bell’s palsy had inducing factors. Avoid these factors may reduce the incidence of Bell’s palsy. Further investigate will fractionize Bell’s palsy to several diseases includ-ing true idiopathic peripheral facial paralysis and some definite diseases.

Objective To explore the effect of recombinant pEGFP-N3-APC vectors carrying various APC functional domains on the expression of β-catenin in human colorectal cancer cells HT-29.Methods The recombinant plasmids were transfected into HT-29 cells mediated by lipofectamine~(TM) 2000, and detected by green fluorescence and RT-PCR. Western blot was applied to detect β-catenin expression level in HT-29 cells after transfection, and gray scales of electrophoresis strips were analyzed by SPSS 13.0.Results Green fluorescence and RT-PCR made clear that all 5 recombinant plasmids were successfully expressed in HT-29 cells. Western blot showed that β-catenin expression level in HT-29 cells was not affected after being transfected with pEGFP-N3-APC1, pEGFP-N3-APC2 and pEGFP-N3-APC3, and was distinctly affected after being transfected with pEGFP-N3-APC4 and pEGFP-N3-APC5, especially the later one. Conclusion The selected APC5 gene fragment with 15-amino acid repeats and SAMP repeats, which is relatively short, can degrade β-catenin level in HT-29 cells and may be applied in the gene therapy.

Objective To evaluate the value of the short-segment nerve conduction studies (SSCSs, inching test) in the diagnosis and localization of cubital tunnel syndrome (CubTS).Methods The clinical and electrophysiologic data of 46 patients (92 limbs from 32 men and 14 women, aged from 19 to 59 years, with average age of 41.2 years) with CubTS were collected.The symptoms occurred in unilateral arm in 41 patients and bilateral arms in 5 patients, involving 35 left arms and 16 right arms.SSCSs were performed in both arms in all the 46 patients.Sixty ulnar nerves were studied in 30 healthy control subjects using SSCSs.Results The 51 symptomatic arms with CubTS were abnormal in long segment motor nerve conduction studies.There were 68 abnormal arms ( 51 symptomatic arms, 17 asymptomatic arms ) in SSCSs.The lesions were located 2 cm proximal to the elbow-the elbow segment ( AE2-E ) in 41 arms (44.6%),the elbow-2 cm distal to the elbow segment (E-BE2) in 23 arms (25%), 4 cm proximal to the elbow-2 cm proximal to the elbow segment (AE4-AE2) in 18 arms (19.6%), 6 cm proximal to the elbow-4 cm proximal to the elbow segment (AE6-AE4) in 9 arms (9.8%), 2 cm distal to the elbow-4 cm distal to the elbow segment (BE2-BE4) in 8 arms(8.6%) and 4 cm distal to the elbow-6 cm distal to the elbow segment (BE4-BE6) in 6 arms(6.5%),respectively.Conclusions SSCSs are more sensitive in detecting CubTS than the conventional long segment motor conduction studies.SSCSs could precisely localize the entrapment lesions in patients with CubTS ,might be a useful tool for the detection of ulnar mononeuropathy at the elbow, especially for diagnosing the patients with CubTS who have no clinical features or have a normal long segmental nerve conduction findings.
