Anxiety/depression symptoms and sleep quality in patients with menstrual migraine / 四川精神卫生

ObjectiveTo assess the anxiety and depression symptoms and sleep quality in patients with menstrual migraine， so as to provide references for the prevention and treatment of menstrual migraine and its comorbidity. MethodsAccording to the diagnostic criteria of the International Classification of Headache Disorder， third edition （ICHD-3）， 501 female migraine patients， including 112 patients with menstrual migraine and 389 patients with non-menstrual migraine， who attended the outpatient clinic of the Affiliated Hospital of North Sichuan Medical College from February 2019 to February 2020， were selected for the study. The general and clinical data of the patients were collected， meantime， patients were assessed using Hamilton Anxiety Scale （HAMA）， Hamilton Depression Scale-24 item （HAMD-24）， 6-item Headache Impact Test （HIT-6） and Pittsburgh Sleep Quality Index （PSQI）. ResultsThe detection rates of pure anxiety， pure depression， comorbid anxiety-depression and sleep disorders in patients with menstrual migraine were higher than those in patients with non-menstrual migraine （χ2=4.198， 4.355， 5.236， 8.624， P<0.05 or 0.01）. Patients with menstrual migraine had higher scores of HAMA、HAMD-17、PSQI and HIT-6 than those of non-menstrual migraine patients （Z=-3.550、-2.723、-2.482、-4.717，P<0.05 or 0.01）. Correlation analysis showed that PSQI score of menstrual migraine patients was positively correlated with HAMA score （r=0.338， P<0.01）， HAMD-24 score （r=0.372， P<0.01） and HIT-6 score （r=0.192， P<0.05）. ConclusionCompared with non-menstrual migraine patients， patients with menstrual migraine experience more severe anxiety and depression symptoms and sleep problems and suffer greater negative life impacts. In addition， the influence of anxiety and depression symptoms and headache on daily life is associated with sleep quality.

3D printed external fixator for treatment of tibial fractures / 中华骨科杂志

Objective To investigate the feasibility and primary clinical outcomes of a kind of independent research and development customized 3D printed external fixator in the treatment of tibial fracture.Methods Data of 7 tibial fracture patients who were treated using computer-assisted reduction and 3D printing technique including a new kind of customized external fixator with automatical reduction function from December 2013 to November 2015 were retrospectively analyzed.There were 5 males and 2 females in this cohort.The age of the patients ranged from 25 to 49 years old,with an average age of 38.1 years old.The procedure was as follows.At first,two or three pins were placed separately into the distal and proximal tibia away from fracture site.Then,the CT scanning was performed on the fractured tibia.According to the CT scanning data,the external fixator was designed by computer software and manufactured by the 3D printing technique.The reduction of tibial fracture was achieved automatically after the 3D printed external fixator was connected to the inserted pins.Finally,the accuracy of reduction was assessed by postoperative X-ray image.During the different fracture healing course,the stress environment could be dynamically adjusted by screwing or unscrewing the nuts to fulfill rigid fixation,compression fixation or elastic fixation for the bone healing.Results All the 7 cases had obtained successful reduction by only one time operation with the 3D printed external fixators.The average lateral angulation was 1.42°± 1.13°,and the average anteroposterior angulation was 1.65°± 1.36°,while the average lateral displacement was 1.38± 1.44 mm,and the average anteroposterior displacement was 1.83± 1.30 mm,which were measured from postoperative X-ray image.The individual durations of the operation were 9 min,8 min,9 min,1.5 min,1.4 min,1.4 min and 2.4 min,respectively.All fractures had achieved bony union in 19-25 weeks after operation,with an average time of 21.4±1.6 weeks.All patients were followed up for 6 months when removal of the external fixator,and no refracture occurred.Conclusion The customized 3D printed external fixator has the function of automatical reduction.In addition,it can provide three kinds of fixation modes,which are rigid fixation,compression fixation and elastic fixation.It has the advantages of simple operation,accurate reduction,reasonable fixation,etc.

Effect of soft tissue thickness of upper lip on lip retraction in orthodontical-treated Class II, Division 1 females / 中南大学学报(医学版)

OBJECTIVE@#To establish the Chinese Han national criteria for the thickness of upper lip in Chongqing and to investigate the effect of lip thickness on lip retraction in orthodontic treatment.
@*METHODS@#A total of 240 adult patients (male=120, female=120) of Chinese Han nationality aged 18-35 years in Chongqing were treated with cephalograms and measured the thickness of upper lip. We established the Chinese Han national criteria for the thickness of upper lip in Chongqing according to the results. Sixty-eight female patients with Angle II 1 from Department of Orthodontics Stomatological Hospital of Chongqing Medical University were treated with maxillary premolars extraction, and pre- and post-treated with lateral cephalograms, then divided into 3 groups according to our criteria: a thin lips group, a normal lips group and a thick lips group. The ratio of the incisors retraction and the upper lip retraction were measured and calculated. The correlation between incisors retraction and the upper lip retraction was analyzed by the Pearson correlation method.
@*RESULTS@#There was statistical significance in the thickness of upper lip between males and females (P<0.01). The ratio of maxillary inscior retraction to the upper lip soft tissue retraction was 1.6:1, 2.2:1 and 2.9:1 in the thin lips group, the normal lips group and the thick lips group, respectively.
@*CONCLUSION@#Gender differences exist in the thickness of upper lip. Upper lip retraction with the incisors was negatively correlated with the soft tissue thickness of the upper lip in females with Angle II 1.

Analysis of HPV subtype infection in 4 037 healthy women in Haikou area / 中华微生物学和免疫学杂志

Objective To investigate the infection of 23 kinds of human papillomavirus ( HPV) subtypes in female cervical epithelium samples and to analyze their relationships with age and results of cyto-logic test in Haikou area. Methods A total of 4 037 local healthy women were enrolled in this study from July 2013 to August 2016, 1 967 of whom received cervical cytology test. Cervical cell samples collected from those women were detected for HPV typing by using PCR-reverse dot blot hybridization. Results (1) The total positive rate of HPV in 4 037 samples was 22. 15% (894 cases), and the detection rates of carci-nogenic, possibly carcinogenic and non-carcinogenic HPV were 16. 13%, 3. 99% and 5. 55% (651, 161 and 224 cases), respectively. The positive rates of 6 genotypes were high, which were HPV52, 53, 81, 51, 16 and 58 in turn. (2) The detection rates of carcinogenic, possibly carcinogenic HPV and some of the gen-otypes (HPV18, 52, 53, 66) increased with age (all P<0. 05). (3) Multiple infection in HPV-positive women accounted for 24. 38% (218/894), in which the infection rates of carcinogenic types declined with age and the numbers of HPV genotypes in carcinogenic infections were negatively correlated with age ( both P<0. 05). (4) Only 2. 49% (49/1 967) of the samples were positive for cervical cytologic test, classified into the ≥ASC-US ( atypical squamous cells of undetermined significance ) group. The detection rates of eight kinds of carcinogenic and two kinds of possibly carcinogenic HPV in≥ASC-US group were significantly higher than those in the negative (no intraepithelial lesion or malignant lesion, NILM) group (all P<0. 05). Conclusion This study indicates that Haikou women have higher rates of HPV infection, especially the eld-erly group. HPV subtype infections present some regional characteristics and are mainly single type infec-tion. Cervical cancer screening should be combined with tests for HPV and cytology analysis to improve its effectiveness.

Changes of cardiac rhythms in a swine model of adult asphyxial cardiac arrest / 中华急诊医学杂志

Objective To observe the changes of cardiac rhythms in a swine model of adult asphyxia! cardiac arrest. Method Sixteen Pigs were aphyxiated by endotracheal tube clamping until 8 min after loss of aortic pulsations. Resuscitation was then provided and swinds were assigned to received 0.045 mg/kg epinephrine intravenously after 3 min of basic life support. The animals with restoration of spontaneous circulation within 20 min from CPR were defined as successfully resuscitated, while the rest were identified as unresuscitation. Electrocardiogram ( EGG) were monitored from the start of asphyxia to the start of the CPR. Results When loss of pulsations occurred, 2 of 16 animals had ventricular fibrillation; 10 pigs exhibited pulseless electrical activity, and 4 pigs had asystole. During the 8 min after the loss of aortic pulsations, pulseless electrical activity converted to VF in 7 pigs. Immidiatedly prior to resuscitation, VF occurred in 9 pigs, asystole in 4 pigs, and PEA in 3 pigs. Conclusions Most of animals in this swine model of asphyxial cardiac arrest presented PEA, but most of them converted to VF especially late in the asphyxial process.
