Objective To evaluate the accuracy and safety of pedicle-scope assisted pedicle screw fixation and percutaneous pedicle screw fixation for treating lumbar degenerative disease(LDD).Methods Thirty cases of LDD treated by mini-invasive transforaminal lumbar interbody fusion(TLIF) under microscope plus percutaneous pedicle screw fixation with fluoroscopy or pedicle-scope of lumbar spine from December 2013 to September 2015 were selected and divide into the percutaneous group and pediclescope group,15 cases in each group.The operative duration,intraoperative blood loss volume,hospital stay and complications were compared between the two groups.The clinical effects were assessed with visual analogue scale(VAS) and Oswestry disability index(ODI).The plain radiography,dynamic radiology and lumbar magnetic resonance imaging(MRI) and computed tomography (CT) were re-examined after operation for assessing the screw location and fusion rate.Results Eighty-four screws were placed in the percutaneous group and 70 screws in the pedicle-scope group.In the percutaneous group and pedicle-scope group,the mean intraoperative blood loss volume,mean operative duration,average times of C-arm fluoroscopy,mean length of hospital stay,mean time of off-bed and complication occurrence rate were measured,and the differences were not statistically significant (P＞ 0.05).In 6-month follow up,the VAS score and ODI score in the two groups were significantly improved compared with before operation(P＜0.01);the VAS score and ODI score were(2.50 ± 1.30) and (50.00-±-3.50) in pediclescope group,(3.00± 1.50) and (58.00 ±4.50) in percutaneous group,respectivehy,and the differences were statistically significant(P＜0.05);the improvement rates of clinical symptoms in the percutaneous group and pedicle-scope group were 73.33 ％ and 80.00 ％ respectively.The imaging reexamination showed that the placed screw location was good and lesion segment fusion was good without screw loosening.The location of 3 screws in the percutaneous group was deviated and adjusted by the second operation.Conclusion The accuracy and safety of pedicle-scope assisted screw placing for treating LDD are higher than those of conventional percutaneous pedicle screw fixation,moreover the operative time is shorter with less intraoperative bleeding.

Cervical cancer is one of the most common gynecological malignancies which seriously threatens the health of women. How to further expand the scope of screening and improve the sensitivity and specificity of screening and optimize screening programs are the key points of cancer prevention and treatment. At present,the screening methods that are commonly used at home and abroad include cervical smear cytology, human papillomavirus ( HPV) detection,molecular biology detection and genetic genetic testing. Cervical smear cytology has high specificity and low sensitivity,the sensitivity of HPV detection is high,but the specificity is low,and the molecular biological detection and genetic testing has high specificity and high sensitivity,but due to the lack of large quantities of clinical samples,and the higher detection cost,they are still in the test study stage.

Objective To investigate the correlation between TCM syndrome types and solar term of onset in patients with gastric cancer.Methods A total of 359 patients with gastric cancer admitted to the Cancer Center of the First Affiliated Hospital of Guangzhou University of Chinese Medicine from January 2020 to August 2023 were included in this study,and the frequency distribution method was used to analyze their information such as sex,age,solar term of onset,differentiation,metastasis and TCM syndrome type.The solar term of onset corresponding to the onset date was calculated,and then the association between solar term of onset and TCM syndrome type in gastric cancer was analyzed.The circular distribution method was used to explore the peak of solar term of onset and TCM syndrome type.Results Among the 359 patients with gastric cancer included in this study,male patients were more than female patients(1.69∶1).The age of onset was mainly between 60 and 70 years old(117 cases,32.6%),and male patients(85 cases,72.6%)were more than female patients(32 cases,27.3%)in this age group.The most common TCM syndromes were qi and blood deficiency syndrome(160 cases,44.6%)and phlegm damp condensation syndrome(94 cases,26.2%).The onset of the disease mainly occurred in winter(132 cases,36.8%),and the peaks were light snow(31 cases,23.5%),major cold(25 cases,18.9%),heavy snow(23 cases,17.4%)and the start of winter(22 cases,16.7%).Qi and blood deficiency syndrome and phlegm damp condensation syndrome in patients with gastric cancer were correlated with solar terms and seasons(P<0.05).The 285 patients with gastric cancer were mainly poorly differentiated gastric cancer(175 cases,61.4%),mainly concentrated in winter(66 cases,37.7%).The main route of gastric cancer metastasis is lymph node metastasis,followed by liver and abdominal cavity metastasis.Conclusion Qi and blood deficiency syndrome and phlegm dampness condensation syndrome are common in patients with gastric cancer.The onset time of gastric cancer is mostly in winter,and the syndrome type is significantly correlated with the onset solar term and differentiation degree.

Objective:To systematically evaluate the effects of body mass index (BMI) on the prognosis of patients with diffuse large B-cell lymphoma (DLBCL).Methods:The databases (PubMed, Medline,Web of Science) were searched to identify clinical literatures about the relationship between BMI and the prognosis of DLBCL according to the inclusion and exclusion criteria. RevMan 5.3 software was used to analyze hazard ratio ( HR) and 95% confidence interval (95% CI) of overall survival (OS) and progression-free survival (PFS); the quality of included literatures, publication bias risk and heterogeneity were also evaluated. Results:There were 12 articles included in our research. Meta-analysis result showed that compared with normal weight patients (BMI 18.5-24.9 kg/m 2), the overweight patients (BMI 25.0-29.9 kg/m 2) had longer OS and PFS time, while the differences were not statistically significant (OS: HR=0.93, 95% CI 0.78-1.11, P=0.42; PFS: HR=0.89, 95% CI 0.67-1.20, P=0.45). The under-weight (BMI < 18.5 kg/m 2) (OS: HR=1.97, 95% CI 1.41-2.74, P < 0.01; PFS: HR=1.89, 95% CI 1.19-3.03, P < 0.01) and the obesity (BMI≥30.0 kg/m 2) patients both had shorter OS and PFS time, but the latter had no statistically significant difference (OS: HR=1.15, 95% CI 0.88-1.51, P=0.31; PFS: HR=1.32, 95% CI 0.90-1.94, P=0.15). No publication bias was observed in the symmetric funnel plot analysis. Conclusion:The increased BMI within a certain range is a protective factor for the prognosis of DLBCL patients.

We tried to explore the value of contrast echocardiography (CEcho) on evaluating hypertrophic cardiomyopathy (HCM) with the inferior wall hypertrophy. A total of 114 patients with HCM were investigated. All the patients received CEcho and routine echocardiography (Echo), and 45 of them received cardiac magnetic resonance (CMR) and 47 of them received Holter. The frequency and percentage of inferior wall hypertrophy were analyzed in HCM patients, as well as the structure and function. The results showed that: (1) Inferior wall hypertrophy was detected in 55 patients (48%) by Echo, while 68 patients (60%) by CEcho. (2) There was no significant difference between CMR and CEcho in the measurement of inferior wall at end-diastole and end-systole. Thickness of inferior wall by CEcho tended to be higher than CMR. However, the inferior wall thickness measured by Echo was obviously lower than that by CMR ( < 0.05) and CEcho ( < 0.05). (3) Bland-Altman plot suggested good consistency between CEcho and CMR in measuring inferior wall thickness. 95% CI of mean differences in inferior wall thickness between CEcho and CMR were smaller in HCM patients as compared with that between Echo and CMR. Unary linear regression analysis showed good degree of fitting between CEcho and CMR. (4) Holter showed that HCM patients with inferior wall hypertrophy were likely to have higher incidence of premature ventricular complexes (PVC) ≥ 500/24 h. We demonstrate that CEcho is rather sensitive in detecting inferior wall hypertrophy. Echo may underestimate the inferior wall thickness. The risk of ventricular premature beats may increase in HCM patients with inferior hypertrophy.
