OBJECTIVE:
To investigate the effect of moxibustion on central insulin resistance related proteins of the rats suffering from diabetic cognitive decline, and analyze the underlying mechanism of moxibustion for cognition improvement.
METHODS:
Using the intraperitoneal injection of STZ combined with a high-fat diet, the rat model of diabetic cognitive decline were prepared. Twenty successfully-modeled rats were assigned randomly into a model group and a moxibustion group, 10 rats in each one. Besides, a blank group was set up with 10 rats collected. In the moxibustion group, suspending moxibustion was applied to "Baihui" (GV20), "Shenting" (GV24) and "Dazhui" (GV14) at the same time, 20 min in each intervention, once a day, and 6 interventions were delivered weekly and the duration of treatment was consecutive 4 weeks. The random blood glucose was measured using glucometer, and the learning-memory ability was detected by water maze test. HE staining was used to observe the morphology of neurons in the hippocampal tissue, real-time PCR assay was to detect mRNA expression of insulin receptor substrate 1 (IRS1), phosphatidylinositol 3-kinase (PI3K) and protein kinase B (AKT) in the hippocampal tissue. The Western blot method was employed to detect the protein expression of IRS1, PI3K, AKT, phosphorylated IRS1 (p-IRS1), phosphorylated PI3K (p-PI3K) and phosphorylated AKT (p-AKT) in the hippocampal tissue, and the ratio of p-IRS1/IRS1, p-PI3K/PI3K and p-AKT/AKT was calculated separately. The immunofluorescence intensity of p-IRS1, p-PI3K, and p-AKT was measured using immunofluorescence.
RESULTS:
Compared with the blank group, the rats of the model group exhibited higher random blood glucose (P<0.001), longer escape latency (P<0.001), severe pathological damage in the hippocampus, lower mRNA expression of IRS1, PI3K, and AKT (P<0.001), reduced ratio of p-IRS1/IRS1, p-PI3K/PI3K and p-AKT/AKT (P<0.001), and declined immunofluorescence intensity of p-IRS1, p-PI3K, and p-AKT in the hippocampal tissue (P<0.001). In comparison with the model group, for the rats of the moxibustion group, the random blood glucose decreased (P<0.05), the escape latency was shortened (P<0.01), the hippocampal pathological damage was attenuated, the mRNA expression of IRS1, PI3K and AKT increased (P<0.01), the ratio of p-IRS1/IRS1, p-PI3K/PI3K and p-AKT/AKT was elevated (P<0.01, P<0.05), and the immunofluorescence intensity of p-IRS1, p-PI3K, and p-AKT in the hippocampal tissue was strengthened (P<0.01, P<0.05).
CONCLUSION
In diabetic rats experiencing cognitive decline, moxibustion can enhance the learning-memory ability, which may be attributed to modulating the protein expression of IRS1, PI3K, and AKT, and their phosphorylation, activating insulin signal transduction, and reducing central insulin resistance.

OBJECTIVE:
To observe the effects of moxibustion at different temperatures on cognitive function and blood glucose levels in patients with cognitive impairment associated with type 2 diabetes mellitus (T2DM).
METHODS:
A total of 66 T2DM patients with cognitive impairment were randomly assigned to a high-temperature group (22 cases, 1 case dropped out, 1 case was eliminated), a medium-temperature group (22 cases, 2 cases were eliminated), and a low-temperature group (22 cases, 2 cases were eliminated). All groups received moxibustion at Baihui (GV20), Dazhui (GV14), and Shenting (GV24) based on their existing glycemic control treatment. Moxibustion temperatures were maintained at 44-46 ℃ (high-temperature group), 41-43 ℃ (medium-temperature group), and 38-40 ℃ (low-temperature group), respectively, for 20 min per session, every other day, 3 times a week for 3 months. The Montreal cognitive assessment (MoCA) score, mini-mental state examination (MMSE) score, short-term memory (STM) accuracy and average reaction time, Rey-Osterrieth complex figure (ROCF) score, fasting plasma glucose (FPG), and glycated hemoglobin (HbA1c) were assessed before and after treatment. Clinical efficacy was evaluated after treatment.
RESULTS:
After treatment, MMSE scores in all three groups were higher than those before treatment (P<0.05). In the high-temperature group, the total MoCA score and the scores of visuospatial and executive function, memory and delayed recall, attention, naming, language, and abstraction were higher than those before treatment (P<0.05); the scores of ROCF copy, immediate recall, and delayed recall were higher than those before treatment (P<0.05); the HbA1c level was lower than that before treatment (P<0.05). In the medium-temperature group, the total MoCA score and the scores of memory and delayed recall, attention, and language were higher than those before treatment (P<0.05). STM accuracy was higher than before treatment (P<0.05), and STM average reaction time was shorter than before treatment (P<0.05) in both the high-temperature and medium-temperature groups. After treatment, the total MoCA score and the scores of visuospatial and executive function, memory and delayed recall, attention, and language in the high-temperature group were higher than those in the medium- and low-temperature groups (P<0.05); MMSE score, STM accuracy, and ROCF immediate recall and delayed recall scores were higher than those in the medium- and low-temperature groups (P<0.05); STM average reaction time was shorter than that in the medium- and low-temperature groups (P<0.05); HbA1c level was lower than that in the low-temperature group (P<0.05). The total MoCA score, attention score, and MMSE score in the medium-temperature group were higher than those in the low-temperature group (P<0.05), and STM average reaction time was shorter than that in the low-temperature group (P<0.05). There were no statistically significant differences in FPG within or between the three groups before and after treatment (P>0.05). The total effective rates were 75.0% (15/20) in the high-temperature group, 50.0% (10/20) in the medium-temperature group, and 15.0% (3/20) in the low-temperature group; the total effective rate in the high-temperature group was significantly higher than that in the low-temperature group (P<0.05).
CONCLUSION
Moxibustion at different temperatures has a dose-effect relationship in treating cognitive impairment in T2DM patients. A temperature range of 44-46 ℃ is more effective in improving cognitive function and stabilizing average blood glucose levels over 2-3 months.

OBJECTIVE:
To observe the clinical effect and safety of Jiuci renmai therapy (moxibustion and acupuncture on the conception vessel) combined with bladder function training in treatment of post-stroke neurogenic bladder (PSNB).
METHODS:
Sixty patients with PSNB were randomly divided into an observation group and a control group, 30 cases in each group. On the basis of conventional treatment with western medication, bladder function training was delivered in the control group, once a day for 4 weeks. In the observation group, Jiuci renmai therapy was supplemented besides the regimen as the control group. The main acupoints were Guanyuan (CV4), Zhongji (CV3), Qihai (CV6) and Qugu (CV2); and the supplementary acupoints were Henggu (KI11), Zhongwan (CV12), Xiawan (CV10) and Shuifen (CV9). Warm needling and moxibustion were operated, once every other day, for 4 weeks. Separately, before treatment and in 2 and 4 weeks of treatment, the urodynamic parameters were detected in the two groups, including maximal urine flow rate (Qmax), maximal detrusor pressure (PdetQmax), residual urine volume (RUV), maximal bladder capacity in the filling phase (MCC), and maximal intravesical pressure in the voiding phase (Pvesmax); the voiding parameters (the average daily number of micturition, urinary leakage episodes, and single voiding volume) were recorded; neurogenic bladder symptom score (NBSS), lower urinary tract symptom score (LUTS) and the score of quality of life scale for incontinence of urine (I-QoL) were evaluated, as well as the clinical effect and safety in the two groups.
RESULTS:
In 2 and 4 weeks of treatment, Qmax, PdetQmax, MCC, Pvesmax, and average daily single voiding volume were increased compared with the levels before treatment in each group (P<0.05), and the above indexes in the observation group were higher than those of the control group (P<0.05). RUV, the average daily number of micturition, urinary leakage episode, NBSS and LUTS scores of the two groups were reduced in comparison with those before treatment (P<0.05 ), and these indexes in the observation group were lower than those of the control group (P<0.05). In 4 weeks of treatment, the average urinary leakage episode was reduced largely in comparison with the control group (P<0.05); and the improvement in RUV for the patients with retention of urine in the observation group was superior to the control group (P<0.05). In 4 weeks of treatment, the score of each dimension in I-QoL and the total score were elevated compared with those before treatment in the two groups (P<0.05), and the scores in the observation were higher when compared with the control group (P<0.05). The total effective rate in the observation group was 90.0% (27/30) which was higher than 70.0% (21/30) of the control group (P<0.05). The incidence of adverse reactions was 3.3% (1/30) in the observation group, which was not significantly different from that in the control group [10.0% (3/30), P>0.05].
CONCLUSION
The combination of Jiuci renmai therapy and bladder function training can effectively alleviate clinical symptoms, recover bladder voiding function, and improve the quality of life in the patients with PSNB, presenting the favorable safety profile in treatment.

OBJECTIVE:
To investigate the effects of Huayu Tongluo (transforming stasis and unblocking collaterals) moxibustion on cognitive function and insulin resistance in patients with type 2 diabetes mellitus (T2DM) and cognitive decline.
METHODS:
Ninety patients with T2DM and cognitive decline were randomly divided into a moxibustion group (n=45, 3 cases dropped out, 2 cases were eliminated) and a waiting moxibustion group (n=45, 2 cases dropped out). Both groups received routine hypoglycemic treatment for 12 weeks. The moxibustion group additionally received Huayu Tongluo moxibustion at Baihui (GV20), Shenting (GV24), and Dazhui (GV14). Pressing moxibustion was applied to Baihui (GV20) for 20 min, while suspended moxibustion was applied to Shenting (GV24) and Dazhui (GV14) for 20 min each. Treatments of moxibustion were administered every other day (three times per week) for 12 weeks. All patients were followed up for 12 weeks, during which their original hypoglycemic medication regimen was maintained. Before treatment, after 12 weeks of treatment, and at the 12-week follow-up, the scores of Montreal cognitive assessment (MoCA), mini-mental state examination (MMSE), Addenbrooke's cognitive examination Ⅲ (ACE-Ⅲ), symbol digit modalities test (SDMT), and Athens insomnia scale (AIS) and the insulin resistance index (HOMA-IR) were observed in the two groups.
RESULTS:
Compared with before treatment, the MoCA scores, MMSE scores, ACE-Ⅲ subscale scores (attention, memory, language fluency, language, visuospatial ability) and total scores, and SDMT scores were increased (P<0.01), while the AIS scores were decreased (P<0.05) in the moxibustion group after treatment and at follow-up. Compared with before treatment, the MMSE score, ACE-Ⅲ subscale scores (memory, attention) and total score after treatment, as well as the ACE-Ⅲ subscale scores (language, memory, attention) and total score, and SDMT score at follow-up were increased (P<0.05, P<0.01) in the waiting moxibustion group. Compared with before treatment, HOMA-IR was decreased in both groups after treatment and at follow-up (P<0.01). At follow-up, ACE-Ⅲ subscale scores (attention, memory), and the total score in the moxibustion group were lower than those after treatment (P<0.05, P<0.01), and the ACE-Ⅲ language subscale score, total ACE-Ⅲ score, and SDMT score in the waiting moxibustion group were higher than those after treatment (P<0.01, P<0.05). After treatment and at follow-up, compared with the waiting moxibustion group, the moxibustion group had higher MoCA scores, MMSE scores, SDMT scores, ACE-Ⅲ subscale scores (attention, memory, language fluency) and total scores (P<0.05, P<0.01), and lower HOMA-IR (P<0.05).
CONCLUSION
Huayu Tongluo moxibustion can effectively improve cognitive function in patients with T2DM and cognitive decline. This improvement may be associated with the reduction in insulin resistance.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective:To explore the experience and learning curve of single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach.Methods:Clinical data of 138 patients undergoing single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via oral vestibular approach from Sep. 2019 to Dec. 2021 in the Department of Thyroid and Breast Surgery of Affiliated Hospital of North Sichuan Medical College were retrospectively analyzed. The cumulative sum (CUSUM) method and best-fit curve analysis were used to compare the differences in each index such as operative time, intraoperative bleeding, number of lymph nodes cleared in the central region and postoperative related complications at various stages of the learning curve.Results:All 138 patients underwent single-line suspension rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach, and one patient was converted to open surgery due to large intraoperative bleeding in the mass. There were 14 males and 124 females, mean age (36.07±8.49) years (20-55 years), thyroid tumor size (7.74±6.49) mm (2.4-50mm), 5 cases underwent Subtotal thyroidectomy, 129 cases underwent Unilateral lobectomy + lymph node dissection in the middle region, and 4 cases total thyroidectomy + central zone lymph node dissection. The number of surgical cases corresponding to the apex of the CUSUM learning curve was 45, and the learning curve was divided into two stages: the learning improvement stage (1-45 cases) and the mastery stage (46-138 cases). The operative time, intraoperative bleeding, postoperative hospital stay, and chin numbness were all lower in the proficiency period than in the learning and training period ( P<0.05), and the number of lymph nodes cleared in the central region was larger than that in the learning and improvement stage ( P<0.05), while the differences in other indexes between the two stages were not statistically significant ( P>0.05) . Conclusion:The single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach has clinical application value and is worth promoting, and the number of surgical cases to be accumulated to master this technique is 45.
