[Application of TELSA structured education program in adults with type 1 diabetes mellitus].

Objective: To evaluate the effect of TELSA structured education program in adults with type 1 diabetes mellitus (T1DM) in China. Methods: From January 2019 to January 2020, 64 adult T1DM patients who met the standard of entry and had the intention to participate in TELSA structured education program were selected from the outpatient of type 1 diabetes comprehensive management in the Second Xiangya Hospital as intervention group. A total of 64 patients matched by age and sex were enrolled as the control group. During the program, the intervention group lost 3 cases and the control group lost 4 cases. Finally, there were 61 effective samples in the intervention group and 60 effective samples in the control group. The patients in the control group were given face-to-face education by a T1DM educator for about 2 hours. The patients in the intervention group were intervened according to TELSA structured education program. The level of glycosylated hemoglobin, the frequency of hypoglycemia, self-management ability and quality of life were evaluated before intervention, 6 months after intervention and 12 months after intervention. Results: The ages of the intervention group and the control group were 30.0(22.0,43.5) and 29.5(22.3,42.5) (P>0.05), and the proportions of males were 47.54%(29 cases) and 45.00%(27 cases), respectively (P>0.05). There were interaction effects (P<0.05) on the level of glycosylated hemoglobin, self-management ability and quality of life in the two groups. At 6 and 12 months after intervention of TELSA structured education program, the level of glycosylated hemoglobin in the intervention group decreased from the baseline level (7.87±1.45)% to (7.23±1.06)% and (7.28±0.93)%, respectively, which was significantly lower than that in the control group at 6 months (7.72±1.20)% and at 12 months(7.76±1.24)% (all P<0.05). After TELSA structured education intervention, the scores of self-management scale for adult type 1 diabetes mellitus (SMOD-CA) in the intervention group showed an upward trend (P<0.001), and the scores of diabetes-specific quality of life scale (A-DQOL) showed a downward trend (P<0.001). In contrast, there was no statistically significant difference in the trend of scores in the control group (P=0.853 and 0.227). The comparison between groups at different time points showed that at 6 and 12 months after the intervention, the SMOD-CA scores of the patients in the intervention group were higher than those in the control group (P<0.001), and the A-DQOL scores were lower than those in the control group (P<0.001). Conclusions: The TELSA structured education program can effectively ameliorate glycemic control, with the improvement of self-management ability and quality of life in adult T1DM patients.

Uric acid level and risk of symptomatic intracranial haemorrhage in ischaemic stroke treated with endovascular treatment.

BACKGROUND AND PURPOSE: There are limited data on the association between uric acid (UA) and symptomatic intracranial haemorrhage (SICH) in patients who have undergone mechanical thrombectomy [endovascular treatment (EVT)]. In the present study, we aimed to investigate the role of serum UA level in SICH after EVT in a real-world practice. METHODS: Patients were selected from the Endovascular Treatment for Acute Anterior Circulation Ischemic Stroke (ACTUAL) registry. SICH was identified using the Heidelberg Bleeding Classification. Multivariable logistic regression analysis was performed to explore the relationship between serum UA and SICH. RESULTS: Among 611 enrolled patients, 90 (14.7%) were diagnosed with SICH within 72 h after EVT. Patients with SICH had a significantly higher level of serum UA (median, 341.0 vs. 302.0 µmol/L; P = 0.003) than those without SICH. Univariate logistic regression analysis indicated that patients with UA levels in the fourth quartile, compared with the first quartile, were more likely to have SICH (odds ratio, 2.846; 95% confidence intervals, 1.429-6.003; P = 0.003). The association remained significant after multivariable adjustment for potential confounders. Furthermore, the multiple-adjusted spline regression model showed an inverted U-shaped association between UA and SICH (P = 0.047 for non-linearity). CONCLUSION: Our study indicated that increased serum UA level was independently associated with SICH after EVT in acute ischaemic stroke.

[Safety and short-term efficacy analysis of breast-conserving surgery combined with intraoperative radiotherapy for early-stage breast cancer].

Objective: To analyze the safety and short-term efficacy of breast-conserving surgery combined with intraoperative radiotherapy for early-stage breast cancer. Methods: A total of 101 consecutive patients who received breast-conserving surgery plus intraoperative radiotherapy were recruited to summarize the recent follow-up results and clinicopathological data. Univariate analysis and Logistic regression model were used to evaluate the factors affecting the postoperative adverse reactions and cosmetic effects. Results: Among 101 patients, 4 patients had recurrence or metastasis. The 3-years disease free survival rate was 94.9%, and the 3-years cumulative recurrence rate was 5.1%. Univariate analysis showed that the menstrual status and postoperative whole breast radiotherapy were associated with the postoperative adverse reactions (P<0.05). The T stage and applicator diameter were associated with the cosmetic effect (P<0.05). Multivariate analysis indicated that the diameter of the applicator (OR=3.701, P=0.026) and postoperative whole breast radiotherapy (OR=5.962, P=0.005) were independent factors for the postoperative adverse reactions, and the diameter of the applicator (OR=2.522, P=0.037) was an independent factor for the cosmetic effect. Conclusion: Breast-conserving surgery combined with intraoperative radiotherapy shows safety and good short-term efficacy in low-risk early-stage breast cancer.

[Vestibular incision subperiosteal tunnel access with connective tissue graft for the treatment of Miller classI and II gingival recession].

OBJECTIVE: To evaluate the clinical outcomes of vestibular incision subperiosteal tunnel access (VISTA) with connective tissue graft (CTG) in the treatment of Miller classes I and II localized gingival recession. METHODS: Ten patients with 10 Miller classes I and II localized gingival recessions were enrolled in the study. All defects were equal to or above 2 mm in recession depth. All the patients received treatment with VISTA+CTG. Their clinical parameters, including recession depth (Rec), recession width (RW), keratinized tissue width (KT), clinical attachment loss (CAL), probing depth (PD) were recorded and compared before surgery and 6 months later. The mean root coverage (MRC) and complete root coverage (CRC) were calculated at the end of 6 months. A visual analogue scale (VAS) was used to estimate the patients' discomfort during the operation and during the 2 weeks post-operation. Patient-based aesthetic satisfaction 6 months after surgery was evaluated by a VAS. RESULTS: The mean Rec was (2.65±0.82) mm at baseline, and (0.35±0.58) mm after 6 months. The VISTA+CTG treatment resulted in an improvement of (2.30±0.98) mm in recession depth (P<0.001). MRC was 86.67%±21.94% and CRC reached 70% at the end of 6 months. KT increased (0.90±1.22) mm (P<0.05). Aesthetic satisfaction on the patients' level was 8.30 based on VAS (0=unsatisfied, 10=extremely satisfied). The patients' discomfort during the operation and 2 weeks post operation were 2.40 and 4.30 (0=no pain, 10=extreme pain). Furthermore, clinical outcomes showed no statistically significant difference between the gingival biotypes, and between the teeth positioned in maxillary and in mandibular. CONCLUSION: VISTA+CTG could be an effective treatment for Miller classes I and II localized gingival recession. Clinical outcomes indicated decrease in recession depth and width, and increase in width of keratinized tissue. Patients suffered little pain during the operation and 2 weeks post-operation of healing and accessed good aesthetic satisfaction. VISTA+CTG could be an option for the treatment of Miller classes I and II localized gingival recession.

[Epidemiologic characteristics and strategies on prevention and control of sexually transmitted human immunodeficiency virus/acquired immunodeficiency syndrome in China].

At present, sexual route is the main transmission route of AIDS in China, and its role in the process of AIDS epidemic has been evolving. Various modes of transmission in sexual transmission and the prevention and control strategies adopted by China have also been changing. This paper mainly summarizes the epidemic characteristics of different periods and different modes of transmission of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in China in recent years. The strategies of prevention and control were described from seven aspects, including health education, promotion of condom use, expanded testing, HIV/AIDS antiviral treatment, pre-exposure prophylactic medication, post-exposure prophylactic medication, social organization participation and sexually transmitted diseases prevention and control. Only when innovative and targeted measures according to the evolution of the HIV/AIDS epidemic and various specific methods are complemented by each other, can the transmission of HIV/AIDS through sexual route be effectively prevented and controlled.

The role of peginterferon in nucleos(t)ide-analogue-treated chronic hepatitis B patients: A review of published literature.

Chronic hepatitis B infection (CHB) causes up to 1.0 million deaths annually. Currently, more than 90% of CHB patients worldwide are receiving indefinite nucleos(t)ide analogue (NA) therapy. New strategies for optimizing hepatitis B surface antigen (HBsAg) loss are required for NA-treated patients as the majority are unable to achieve HBsAg loss and may require lifelong therapy. In hepatitis B e antigen (HBeAg)-positive patients, switching from NAs to finite peginterferon (PegIFN) therapy can double HBeAg seroconversion rates. One in five patients who switch to PegIFN can achieve HBsAg loss, whereas patients who continue NA therapy typically do not. In HBeAg-negative NA-treated patients, add-on PegIFN therapy achieves higher, albeit modest, HBsAg loss rates compared with continued NA monotherapy and offers the opportunity for NA-treated patients to achieve the inactive carrier state. In the absence of curative therapies, PegIFN represents a valuable, finite option for NA-treated patients who would otherwise require potentially lifelong therapy.

Comparison of entecavir and lamivudine in preventing hepatitis B reactivation in lymphoma patients during chemotherapy.

During chemotherapy for lymphoma, the administration of cytotoxic agents and rituximab often results in hepatitis B reactivation (incidence, 14-72%). This study was designed to compare the efficacy of entecavir and lamivudine in preventing hepatitis B reactivation in lymphoma patients. Between January 2007 and February 2009, patients treated in four hospitals in China were screened to identify those most appropriate for analysis. These patients received either entecavir or lamivudine during chemotherapy and for 6 months after completion of chemotherapy. A total of 34 patients received entecavir and 89 patients received lamivudine. Compared with the lamivudine group, the entecavir group had significantly lower rates of hepatitis (5.9 vs 27.0%, P = 0.007), hepatitis B reactivation (0 vs 12.4%, P = 0.024) and disruption of chemotherapy (5.9 vs 20.2%, P = 0.042). All patients with hepatitis B reactivation had B-cell non-Hodgkin's lymphoma (stage III-IV). In lymphoma patients under chemotherapy treatment, entecavir is more effective than lamivudine in preventing hepatitis B reactivation. For patients with advanced stage disease, entecavir should be considered the primary preventive therapy.

[Comparison of endoscopic versus conventional surgery for benign parotid tumor: a metaanalysis].

To assess the efficacy and safety of endoscopic versus conventional surgery for benign parotid tumor.We searched the electronic databases including PubMed, Embase, Web of Science, CNKI and Wanfang Data for studies published before January, 2021. A meta-analysis was performed using Rev Man 5.3 software.We retrieved 8 eligible studies involving a total of 532 patients, and 4 of the studies were RCT. The results of meta-analysis showed that endoscopic surgery was better than conventional surgery in terms of incision length (WMD=- 5.73; 95% CI: - 6.84--4.62), intraoperative bleeding volume (WMD=-34.50; 95% CI: -49.09--19.91), postoperative drainage volume (WMD=- 21.72; 95% CI: - 29.31--14.12), subjective satisfaction with incision scar(WMD=2.23; 95%CI: 1.11-3.34), and temporary facial paresis (OR=0.37; 95%CI: 0.17-0.78). There were no significant differences in the operation time, salivary fistula, Frey's syndrome or tumor recurrence between the two groups.For treatment of benign parotid tumor, endoscopic surgery is a safe surgical procedure and is superior to conventional surgery in terms of incision length, operative bleeding volume, postoperative drainage volume, subjective satisfaction with incision scar, and temporary facial paresis.

Comparison of relative potency of intrathecal bupivacaine for motor block in pregnant versus non-pregnant women.

BACKGROUND: Pregnancy is associated with facilitated spread of spinal and epidural anesthesia. There are limited data available for relative potency of motor block of neuraxial local anesthetics in non-pregnant versus pregnant women. The purpose of this study was to investigate the median effective dose (ED(50)) of intrathecal isobaric bupivacaine for motor block in non-pregnant and pregnant women and to estimate the respective potency ratio. METHODS: American Society of Anesthesiologists physical status I and II pregnant (n=35) and non-pregnant (n=35) patients undergoing elective cesarean delivery or elective gynecological surgery under combined spinal-epidural anesthesia were enrolled. According to the up-down sequential allocation technique, the dose of intrathecal isobaric bupivacaine for each patient was determined by the response of the previous patient in both groups. The initial dose of bupivacaine was 4 mg and the testing interval was set at 0.5 mg. Efficacy was determined by the occurrence of motor block in either lower limb as assessed by the modified Bromage scale within 5 min of spinal injection. RESULTS: The ED(50) of intrathecal bupivacaine for motor block was 4.51 (95% confidence interval (CI) 4.27-4.76) mg for non-pregnant women and 3.96 (95% CI 3.83-4.08) mg for pregnant women. The relative potency ratio for motor block for pregnant versus non-pregnant women was 1.14 (95% CI 1.05-1.24), (P=0.0037). CONCLUSIONS: Intrathecal bupivacaine was 1.14 times more potent for motor block in pregnant versus non-pregnant women. Our current data confirm the difference in local anesthetic requirement between non-pregnant and pregnant patients.

The medicinal potential of influenza virus surface proteins: hemagglutinin and neuraminidase.

Nowadays, influenza virus is still a big threat to human. Hemagglutinin (HA) and neuraminidase (NA) are the two viral surface proteins, which play important roles in the life cycle of influenza virus. Current influenza vaccines and anti-influenza drugs work mainly by interfering with the functions of the two proteins. In this review, we will display some recent studies about the two proteins. As to HA, this review covers a lot including its fusion function, receptor specificity, antigenic shift hypothesis, novel antibodies and various inhibitors in order to deeply discuss this protein. As to NA, this review mainly focuses on studies about the newly identified 150-cavity of group-1 NAs and shows some untypical NA inhibitors aiming to provide a broader range of lead compounds for anti-influenza drug design.

[The influence of recombinant human growth hormone on the metabolism of glucose and protein in severely burned patients].

OBJECTIVE: To investigate the influence of recombinant human growth hormone (rhGH) on the metabolism of glucose and protein in severely burned patients. METHODS: The serum levels of total protein and albumin and the incidence of hyperglycemia in 24 cases of severely burned patients treated by rhGH were determined and compared with those in patients without rhGH treatment (control group). RESULTS: The serum levels of total protein (TP) and albumin in burned patients after being treated by rhGH were much higher than those before treatment and those in control group. The blood level of glucose increased within 2 weeks, especially 1 week postburn. The incidences of hyperglycemia were 52.38%, 50.24% and 20% on 0 similar 3, 4 similar 7 and 8 similar 14 postburn days (PBDs), respectively. And the incidences of hyperglycemia were 100%, 50% and 0% when the administration of rhGH started within 1, 2 and after 2 weeks respectively. CONCLUSION: The systemic protein synthesis in severely burned patients could be accelerated by the use of rhGH. But early administration of rhGH in burned patients could affect blood sugar level obviously. And the optimal time to give rhGH is 2 weeks after burn injury.
