Prevalence and Years of Life Lost due to Disability from Dental Caries among Children and Adolescents in Western China, 1990-2015.

OBJECTIVE: To analyze the prevalence and years lived with disability (YLD) from dental caries among children and adolescents and the time trends over the past two decades in Sichuan province, the largest province in west China. METHODS: Based on the Global Burden of Disease Study 2015 (GBD2015), which systematically assessed the epidemiological characteristics of major diseases and their transitions by country and region from 1990 to 2015, we extracted the estimated results for China. We then used the Bayesian meta-regression method to estimate the sex- and age-specific prevalences and YLDs from dental caries among children and adolescents under 15 years old in Sichuan province and compared them with global and national indicators for the same period. RESULTS: In 2015, there were almost 6 million cases of dental caries in children and adolescents (aged < 15 years) in Sichuan province, accounting for 6% of the total cases in China. For children under 5 years, the prevalence of deciduous caries was 55.9%, and the YLDs value was 10.8 per 100,000, while it was 24.3% and 5.1 per 100,000 respectively among 5- to 14-year-olds; for those aged 5 to 14 years, the prevalence of permanent caries was 21.5%, and the YLDs value was 11.5 per 100,000. From 1990 to 2015, the prevalence of dental caries for children under 5 years increased substantially, by 16.2%, and the YLDs increased by 8.7%. Among those aged 5 to 14 years, the prevalence increased and the YLDs decreased. CONCLUSION: Dental caries remains a huge health burden in Western China. In contrast to the global and national data, the trend has increased rapidly over the past 25 years in this region. This work provides suggestions for the prevention and control for oral health in China with the policy of two-child.

[Effect of electroacupuncture of "Biao-Ben" acupoints on renal function and hemorheology and eNOS level in patients with early diabetic nephropathy].

OBJECTIVE: To observe the effect of electroacupuncture (EA) of "Biao-Ben acupoints" (Biao indicates pathogenic factors of disease; Ben refers to body constitution) on renal function, hemorheology and endothelial nitric oxide synthase (eNOS) level in patients with early diabetic kidney disease (DKD), so as to explore its mechanism underlying relieving early DKD. METHODS: A total of 120 patients with early DKD were selected and randomized into 3 groups: medication, conventional acupoints, and "Biao-Ben"acupoints groups by stratified randomization method, with 40 cases in each group. Patients of the me-dication group were treated by routine symptomatic supportive treatment (gleziquantel tablets or subcutaneous injection of insulin \[for hyperglycemia\], candesartan tablet \[hypertension\], simvastatin tablets \[hyperlipidemia\], etc.).Based on the medication group, patients of the conventional acupoint group were treated by EA of bilateral Feishu (BL13), Weiwanxiashu (EX-B3), Weishu (BL21), Shenshu (BL23), Sanyinjiao (SP6), Taixi (KI3) (main acupoints), etc., and those of the Biao-Ben acupoint group treated by EA of main acupoints Zhongwan (CV12), Fenglong (ST40), Xuehai (SP10) and Taichong (LR3) (Biao acupoints), and Guanyuan (CV4) and Zusanli (ST36) (Ben acupoints). The EA treatment was conducted one daily, 5 days a week for 8 weeks. The urine microprotein level in 24 h was detected using an automatic specific protein analyzer, followed by calcula-ting the urine albumin excretion rate (UAER). The serum creatinine (Scr), urea nitrogen (BUN) and cystatin (CysC) contents were detected by using an automatic biochemical analyzer, and the whole blood low-cut viscosity (ηbL), whole blood mid-cut viscosity (ηbM), whole blood high-cut viscosity (ηbH), plasma viscosity (ηp) and fibrinogen (FIB) levels were detected using an automatic hemorheology tester, and the serum eNOS and nitric oxide (NO) levels assayed using enzyme linked immunosorbent assay. The total clinical effective rates were compared and the adverse reactions of the treatment were recorded. RESULTS: Compared with the values before the treatment in each group, the levels of UAER, Scr, BUN, CysC, ηbL, ηbM, ηbH, ηp and FIB were all significantly decreased (P<0.01), while serum eNOS and NO levels significantly increased in the three groups after the treatment (P<0.01). Compared with the medication group, the levels of UAER, Scr, BUN, CysC, ηbL, ηbM, ηbH, ηp and FIB were notably lower (P<0.01, P<0.05), and serum eNOS and NO contents obviously higher in both the conventional acupoint and "Biao-Ben" acupoint groups (P<0.01). Comparison between the two EA groups showed that the levels of UAER, BUN, ηbL, ηbM, ηbH and ηp were lower (P<0.05), whereas the serum eNOS and NO contents were considerably higher (P<0.05) in the "Biao-Ben" acupoint group than in the conventional acupoint group. After the treatment, the total clinical effective rate of the "Biao-Ben" acupoint group was 89.74%(35/39), being significantly higher than those of both the conventional acupoint group (71.05%, 27/38,P<0.05) and medication group (64.10%, 25/39, P<0.05). CONCLUSION: EA of "Biao-Ben" acupoints can improve renal function and reduce microcirculation disorders in patients with early DKD, which may be related to its function in up-regulating the levels of serum eNOS and NO.

[Thumb-tack needle based on Biaoben Genjie theory for dry eye: a randomized controlled trial].

OBJECTIVE: To compare the clinical efficacy of thumb-tack needle and sodium hyaluronate eye drops for dry eye. METHODS: A total of 60 patients with dry eye were randomly divided into a thumb-tack needle group and a western medication group, 30 cases in each group. Based on Biaoben Genjie theory, thumb-tack needle was applied at Zhiyin (BL 67), Lidui (ST 45), Fuyang (BL 59), Yanglao (SI 6), Jingming (BL 1) and Cuanzhu (BL 2) in the thumb-tack needle group, 2 times a week. In the western medication group, 0.1% sodium hyaluronate eye drops were applied, 3 times a day. Both groups were treated for 4 weeks. Before and after treatment, TCM symptom score, tear film break-up time (BUT), SchirmerⅠtest (SⅠT), corneal fluorescein sodium staining (FL) score and 36-item short form health survey (SF-36) score were observed, and the clinical efficacy was evaluated in the two groups. RESULTS: After treatment, the total scores and each item score of TCM symptom in the two groups were decreased compared with before treatment (P<0.05); except for score of visual fatigue and photophobia, the total score and each item score of TCM symptom in the thumb-tack needle group were lower than the western medication group (P<0.05). After treatment, the BUT, SⅠT and SF-36 scores were increased and the FL scores were decreased in the two groups (P<0.05); the BUT, SⅠT and SF-36 score were higher than the western medication group (P<0.05), and the FL score was lower than the western medication group (P<0.05) in the thumb-tack needle group. The total effective rate in the thumb-tack needle group was 93.3% (28/30), which was higher than 80.0% (24/30) in the western medication group (P<0.05). CONCLUSION: Thumb-tack needle based on Biaoben Genjie theory could effectively relieve clinical symptoms of dry eye patients, prolong tear film break-up time, increase tear secretion, improve tear film function and quality of life, and its curative effect is better than sodium hyaluronate eye drops.

Effect of Electroacupuncture on Neurological Deficit and Activity of Clock and Bmal1 in Cerebral Ischemic Rats.

Acute focal cerebral ischemic stroke (IS) is a leading cause of morbidity and mortality worldwide. Acupuncture is an emerging alternative therapy that has been beneficial to acute brain ischemia. However, the underlying protective mechanism of its neuroprotective effect remains unclear. Human original circadian rhythm will be lost after IS, which seriously affects the quality of life and functional recovery of stroke patients. We hypothesize that acupuncture treats IS by regulating the balance of Clock and Bmal1. This study aims to explore the effect of acupuncture at acupoints GV20 and BL23 on neuroprotection and anti-apoptosis in middle cerebral artery occlusion (MCAO) rats and expression of apoptosis and circadian rhythm related proteins. Male Sprague-Dawley (SD) rats were randomly divided into five groups: normal group (Normal), sham model group (Sham MCAO), MCAO model group (MCAO), sham electroacupuncture group (Sham EA) and electroacupuncture group (EA). The MCAO model was prepared by electrocoagulation. The first acupuncture treatment was performed within 2 h after surgery, and then acupuncture therapy was performed on 1st day, 2nd day and 3rd day respectively. After their neurological examination at 72 h of ischemia, the rats from each group were sacrificed. Triphenyltetrazolium chloride (TTC) staining was used to evaluate the brain infarct size. Ultrastructural observation on cerebral ischemic cortex and serum inflammatory cytokines were evaluated. TUNEL staining was used to detect cell apoptosis of brain tissue. The expression levels of proteins Bax, bcl-2, caspase-3, Clock and Bmal1 in the cerebral ischemic region were detected by immunofluorescence staining. Here, we presented evidence that EA at GV20 and BL23 could significantly improve the neurological deficit score and infarct size, and alleviate the cell apoptosis of brain tissue. Moreover, acupuncture treatment upregulated the anti-apoptotic Bcl-2/Bax ratio and reversed the upregulation of caspase-3 following 72-h cerebral ischemia. In addition, the expression levels of circadian proteins Clock and Bmal1 were upregulated in EA group while compared with MCAO group. Our study demonstrated that acupuncture exerted neuroprotective effect against neuronal apoptosis after stroke and the mechanism might be related with regulation of circadian rhythm proteins Clock and Bmal1.

[Moxibustion therapy in prevention and treatment of coronavirus disease 2019 (COVID-19): construction and application of non-contact diagnosis and treatment mode].

OBJECTIVE: To establish and promote the non-contact doctor-patient interactive diagnosis and treatment mode based on mobile internet for the treatment of coronavirus disease 2019 (COVID-19) with moxibustion therapy, and to observe the feasibility and effectiveness of the model in the pandemic. METHODS: A total of 43 first-line medical staff and 149 suspected and confirmed cases with COVID-19 [18 cases in medical observation period, 17 cases of mild type (cold dampness and stagnation in the lung), 24 cases of ordinary type (cold-dampness accumulated in the lung) and 90 cases in recovery period (qi deficiency of spleen and lung)] were included. A non-contact doctor-patient interactive diagnosis and treatment platform was established for the treatment of COVID-19 with indirect moxibustion plaster based on mobile internet. By the platform, the patients were instructed to use indirect moxibustion plaster in treatment. For the first-line medical staff and patients in the medical observation period, Zusanli (ST 36), Qihai (CV 6) and Zhongwan (CV 12) were selected. For the mild cases (cold dampness and stagnation in the lung) and the cases of ordinary type (cold-dampness accumulated in the lung), Hegu (LI 4), Taichong (LR 3), Zusanli (ST 36) and Guanyuan (CV 4) were selected. In the recovery period (qi deficiency of spleen and lung), Dazhui (GV 14), Feishu (BL 13), Geshu (BL 17), Zusanli (ST 36) and Kongzui (LU 6) were used. The treatment was given once daily for 40 min each time. The intervention lasted for 10 days. After intervention, the infection rate and the improvement in the symptoms and psychological status of COVID-19 were observed in clinical first-line medical staff and COVID-19 patients. RESULTS: In 10 days of intervention with indirect moxibustion plaster, there was "zero" infection among medical staff. Of 43 first-line physicians and nurses, 33 cases had some physical symptoms and psychological discomforts, mainly as low back pain, poor sleep and anxiety. After treatment, regarding the improvements in the symptoms and psychological discomforts, the effective rate was 78.8% (26/33) and the curative rate was 36.4% (12/33). Regarding the improvements in psychological discomforts, the effective rate was 58.3% (14/24) and the curative rate was 37.5 (9/24). Of 149 patients, 133 cases had the symptoms and psychological discomforts. After treatment, regarding the improvements in the symptoms and psychological discomforts, the effective rate was 81.2% (108/133) and the curative rate was 34.6% (46/133). Regarding the improvements in psychological discomforts, the effective rate was 76.5% (52/68) and the curative rate was 57.4 % (39/68). CONCLUSION: It is feasible to apply the indirect moxibustion plaster technique based on mobile internet to the treatment COVID-19. This mode not only relieves the symptoms such as cough and fatigue, improves psychological state, but also possibly prevents the first-line medical staff from COVID-19.

[Discussion on needling manipulation of Chifeng Yingyuan].

Regarding the needling manipulation, Chifeng Yingyuan, there are different descriptions in ancient medical literature and the current teaching materials or clinical reports, especially for the understanding recorded in Jinzhenfu Poem of Golden Needle). In the current teaching materials and clinical reports, it is described that the needle is inserted deeply at first, and then shallowly; afterward, the needle tip is pushed to the middle layer and manipulated with lifting, thrusting and rotating technique, combined with twisting and flying method. After analyzing the original description in the book and the feasibility of function and operation, the authors introduced their recognition on its manipulation and techniques in this article. This manipulation should be: the needle is inserted to the middle layer, afterward, the needle body is pulled and tilted toward each of the four directions, on this basis, then twisting and flying method is applied.
