Objective To histomorphometricly assess changes occurred in the alveolar ridge following different methods of socket preservation and to compare them against natural healing without interventions. Methods The second、 third and fourth mandibular premolars were extracted from six beagles. Six extraction sites in each dog were randomly assigned to three treatments as follows:natural healing (T1), Bio-Oss Collagen (T2) and immediate implant with Bio-Oss (T3). Six month after surgery, the dogs were euthanized and tissue samples were sectioned, fixed and mounted, then were stained with toluidine blue. The histologic studies and morphological measurements were performed by using an optical microscope and a digital image software. Results Reabsorption in the buccal aspect of the alveolar crest of ridge was showed in all groups. With respect to the mean vertical bone loss of the buccal bone plate, T3 is lower than T1 and T2(P<0.001 ), while no significant differences were observed between T1 and T2. With regard to horizontal dimension of the alveolar process , a statistical significance could be found at 3mm and 4mm below the crest of ridge in group T1 and T3(P=0.017, P=0.042), while no statistical differences were found between other groups. Conclusions Both techniques of alveolar ridge preservation were not able to completely preserve the original bone volume after tooth extraction. Immediate implant placement in combination with Bio-Oss seems to have the potential to limit the reabsorption of the alveolar process efficiently , but the bone preserving effect of Bio-Oss Collagen is undesirable.

Objective To investigate the value of spiral CT in therapy observation during and after radiofrequency ablation (RFA) for lung or liver tumors. Methods Spiral CT-guided RFA were performed in 35 patients (38 lesions) with lung or liver tumors. CT value of lesions during operation and the changes of lesions after operation were observed. Results Thirty-eight lesions were accurately located under spiral CT. The position of the electrode and the expension of claw-like thin needle electrode could be observed directly. CT value of lesions decreased and some gasification foci in some lesions were observed after RAF therapy. One month after RFA, tumor volume decreased, and the tumors present as slightly low-density mass on contrast-enhanced CT. The total effective rate of RFA was 85.71% (30/35). Conclusion Spiral CT is able to accurately guide RFA treatment for lung or liver tumors and evaluate the efficacy of therapy.

Objective To investigate AXIN2 mRNA expression level in hepatocellular carcinoma (HCC) , and to analyze the effect of AXIN2 gene methylation status on its mRNA expression and HCC genesis and development. Methods Fifty-three surgical excised HCC specimens and paired adjacent non-cancerous specimens, seven normal liver specimens and five HCC cell lines were collected. The expression of AXIN2 at mRNA level and the methylation status of AXIN2 gene promoter were determined by quantitative PCR. Results The expression of AXIN2 mRNA was lower in HCC tissues (0.1629 + 0.0679) than that in adjacent non-cancerous tissues (0. 4155 + 0. 2330), and there was significant difference (Z= -2. 567, P = 0. 010). The methylation level of AXIN2 gene in HCC and adjacent non-cancerous tissues (39. 77% ±3. 89%, and 36. 92% ±2. 81%) was significantly higher than that in normal liver tissues (7. 38% ±2. 40% , t=-3. 663 ,P = 0. 009;t= -4. 591 ,P = 0. 007).AXIN2 gene was hypermethylated in all five HCC cell lines. There was a negative correlation between AXIN2 mRNA expression level and the degree of methylation ( r = -0. 458, P = 0. 032). The methylation level was higher in TNM Ⅲ patients of HCC than that in TNM Ⅰ and Ⅱ patients (P =0.008). Conclusion The down-regulation of AXIN2 gene mRNA expression is correlated with its hypermethylation status. The low expression of AXIN2 mRNA and the abnormal methylation of promoter may be one of the important mechanism of HCC genesis and development.

Objective:To investigate the characteristics and differences of anxiety, depression and sleep disorder among human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients in Guangzhou, then optimize the antiretroviral therapy and provide effective mental intervention.Methods:All HIV/AIDS patients from the outpatient department of Guangzhou Eighth People's Hospital were enrolled in the present study from January 2016 to December 2016. They were evaluated by the hospital anxiety and depression scale and Pittsburgh Sleep Quality Index, to analyze the levels of depression, anxiety and sleep disorder.Results:The incidences of anxiety, depression and sleep disorder were 30.5%(61/200), 31.0%(62/200) and 22.5%(45/200) respectively. 36.1%(22/61) of patients with anxiety and 35.5%(22/62) of patients with depression were accompanied by sleep disorder. The sleep disturbance index were significant higher in HIV/AIDS patients with anxiety ( t=4.065, P<0.001) or depression ( t=3.034, P=0.003) than those without anxiety or depression. Anxiety was mainly found in HIV/AIDS patients in aged 20 to 40 group ( F=7.998, P=0.018), while depression was mostly found in HIV/AIDS patients who didn't receive higher education ( F=13.55, P=0.001), and sleep disorder was more common in people with CD4 + count <200 cells/μl ( t=2.01, P=0.046). Conclusions:Anxiety and depression, which could aggravate sleep disorder, are very common in HIV/AIDS patients. Psychological care need to be strengthened to HIV positive patients in early phase, and screening questionnaires should be conducted before antiretroviral treatment began.

Objective:To observe the effectiveness of bone cement-enhanced proximal femoral nail antirotation (PFNA) in the treatment of severe osteoporotic intertrochanteric fracture.Methods:Between January 2016 and June 2017, 23 patients with severe osteoporotic intertrochanteric fracture were treated with bone cement-enhanced PFNA at Department of Orthopaedics, The Second Affiliated Hospital to Luohe Medical College. They were 9 men and 14 women with an average age of 85.3 years (range, from 80 to 91 years). According to AO/OTA-2018 classification, there were 2 cases of type 31-A1.3, 5 cases of type 31-A2.2, 13 cases of type 31-A2.3 and 3 cases of type 31-A3.3. According to Singh standard grading, 4 cases were rated as level 1, 16 cases as level 2 and 3 cases as level 3. The PFNA fixation was enhanced by bone cement in all. The operation time, amount of intraoperative bleeding, postoperative complications, fracture healing time and hip Harris scores at the last follow-up were recorded.Results:The operation time averaged 56.3 minutes (range, from 47 to 91 minutes) and the amount of intraoperative bleeding 197 mL (range, from 110 to 450 mL). All patients were followed up for 5 to 27 months (mean, 14.7 months). One patient who had been rated as good by the Harris hip score died 5 months after surgery because of acute suppurative obstructive cholangitis. All the 23 fractures achieved bony union. The healing time averaged 11.3 weeks (range, from 8 to 18 weeks). By the Harris scores at the last follow-up, 11 cases were excellent, 10 cases good and 2 cases fair, giving an excellent and good rate of 91.3%.Conclusion:Bone cement-enhanced PFNA can bring about good short-term outcomes for severe osteoporotic intertrochanteric fractures because it can improve the screw control and reduce the risk of internal fixation failure.

【Objective】 To investigate the control rate of blood glucose and its influencing factors in type 2 diabetes mellitus patients in Yulin area. 【Methods】 We selected the adult type 2 diabetes patients who visited our hospital from May 2020 to December 2021 as the subjects. Then we collected their basic information (gender, age, household income, type of medical insurance payment, education level, and duration of disease), measured their height and weight, calculated their body mass index (BMI), detected HbA1c, and measured their subcutaneous and visceral fat. The Chi-square test and multivariate Logistic regression methods were used to analyze the influencing factors. 【Results】 The total attainment rate of HbA1c (HbA1c<7%) among 877 adults with type 2 diabetes was 13.34%. The Chi-square test showed that statistical differences in the attainment rate of HbA1c among different ages, family annual income, type of medical insurance, and duration of disease. Further unconditional multivariate Logistic regression analysis model results showed that the HbA1c attainment rate in 18-44 years old group was 0.418 times higher than that in ≥60 years old group (95% CI=0.219-0.799, P=0.008). The HbA1c compliance rate of patients with employees’ medical insurance was 1.744 times that those with residents’ medical insurance (95% CI=1.131-2.782, P=0.013). The HbA1c attainment rate of diabetic patients with an annual family income of 30 000 yuan to 100 000 yuan was 1.873 times (95% CI=1.074-3.266, P=0.027), and with an annual family income of more than 100 000 yuan was 2.649 (95% CI=1.299-5.404, P=0.007) times than that of diabetic patients with less than 30 000 yuan. 【Conclusion】 The blood glucose control rate in adults with type 2 diabetes mellitus in Yulin area is lower compared with the level of the nation and other regions. Age, annual household income, and type of medical insurance payment are independent influencing factors.

OBJECTIVE:
To evaluate effectiveness of proximal femur bionic nail (PFBN) in treatment of intertrochanteric fractures in the elderly compared to the proximal femoral nail antirotation (PFNA).
METHODS:
A retrospective analysis was made on 48 geriatric patients with intertrochanteric fractures, who met the selection criteria and were admitted between January 2020 and December 2022. Among them, 24 cases were treated with PFBN fixation after fracture reduction (PFBN group), and 24 cases were treated with PFNA fixation (PFNA group). There was no significant difference in baseline data such as age, gender, cause of injury, side and type of fracture, time from injury to operation, and preoperative mobility score, American Society of Anesthesiologists (ASA) score, Alzheimer's disease degree scoring, self-care ability score, osteoporosis degree (T value), and combined medical diseases between the two groups ( P>0.05). The operation time, intraoperative blood loss, number of blood transfusions, transfusion volume, length of hospital stay, occurrence of complications, weight-bearing time after operation, and postoperative visual analogue scale (VAS) score, walking ability score, mobility score, self-care ability score were recorded and compared between the two groups. And the radiographic assessment of fracture reduction quality and postoperative stability, and fracture healing time were recorded.
RESULTS:
The operations in both groups were successfully completed. All patients were followed up 6-15 months with an average time of 9.8 months in PFBN group and 9.6 months in PFNA group. The operation time was significantly longer in PFBN group than in PFNA group ( P<0.05), but there was no significant difference in intraoperative blood loss, number of blood transfusions, transfusion volume, length of hospital stay, change in activity ability score, and change in self-care ability score between the two groups ( P>0.05). The weight-bearing time after operation was significantly shorter in PFBN group than in PFNA group ( P<0.05), and the postoperative VAS score and walking ability score were significantly better in PFBN group than in PFNA group ( P<0.05). Radiographic assessment showed no significant difference in fracture reduction scores and postoperative stability scores between the two groups ( P>0.05). All fractures healed and there was no significant difference in fracture healing time between the two groups ( P>0.05). The incidence of complications was significantly lower in PFBN group (16.7%, 4/24) than in PFNA group (45.8%, 11/24) ( P<0.05).
CONCLUSION
Compared with PFNA, PFBN in the treatment of elderly intertrochanteric fractures can effectively relieve postoperative pain, shorten bed time, reduce the risk of complications, and facilitate the recovery of patients' hip joint function and walking ability.
