Abstract
Enamel matrix proteins (EMP) are deposited on the surface of developing roots before dentin formation and may play a role in osteogenesis. Amelogenins (Am) are the main and active component in EMPs. Studies had showed great clinical values of EMPs in periodontal regenerative treatment and other fields. By affecting the expression of growth factors and inflammatory factors, EMPs could act on various periodontal regeneration-related cells to promote angiogenesis, anti-inflammation, bacteriostasis and tissue healing, achieving the clinical effect of periodontal tissue regeneration (newly generated cements and alveolar bones as well as functionally penetrated periodontal ligament). EMPs alone or combined with bone graft material and barrier can be used for regenerative surgical treatment in intrabony defects and degree Ⅱ furcation-involved at maxillary buccal or mandibular teeth. EMPs can also be adjunctively used to treat recession type 1 or 2 gingival recessions, forming periodontal regeneration on the exposed root surface. Through a comprehensive understanding of the principle and current clinical application of EMPs on periodontal regeneration, we can look forward to their future development. The development of recombinant human amelogenin to replace animal-derived EMPs through bioengineering technologies, the study of the clinical application of EMPs combined with other collagen biomaterials, and the specific application of EMPs in severe soft and hard periodontal tissue defects and peri-implant lesions are all important development directions of future EMPs-related researches.

Abstract
Objective: To evaluate the association between periodontitis and mild cognitive impairment (MCI), and explore the potential local oral risk factors for MCI. Methods: The study included 70 middle-aged and elderly subjects (44 females and 26 males) with periodontal disease who were first diagnosed by the Department of Periodontology or referred by the Department of Geriatrics in Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from January 2021 to January 2022. In this study, the control group consisted of periodontal disease patients without cognitive impairment, and the case group (MCI group) consisted of those diagnosed with MCI referred by the geriatrics specialists. Full-mouth periodontal examinations of all subjects were performed and periodontal indicators were recorded by periodontists, while digital panoramic radiographs were taken. The severity of periodontitis was defined according to the 1999 classification, and the staging and grading of periodontitis were defined according to the 2018 American Academy of Periodontology and European Federation of Periodontology classification. The mini-mental state examination scale was chosen by geriatricians to evaluate the cognitive function of the included subjects. The cubital venous blood was drawn to detect the expression levels of inflammatory factors such as hypersensitive C-reactive protein (hs-CRP), interleukin (IL)-1β, IL-6 and tumor necrosis factor-α(TNF-α) in serum. Independent-samples t test and chi-square test were used to analyze the differences in population factors, periodontal-related indexes and serum inflammatory factors between the two groups (α=0.05). Odds ratios (OR) for MCI according to the severity of periodontitis and main periodontal clinical indexes were calculated by binary Logistic analysis. Results: Thirty-nine subjects were included in the control group and thirty-one in the MCI group. The age of the study population was (58.3±6.2) years (range: 45-70 years). The comparison between two groups showed that the control group was with higher educational background (χ²=9.45, P=0.024) and 2.6 years younger than the MCI group [(57.1±6.0) years vs. (59.7±6.3) years, t=-1.24, P=0.082]. The number and proportion of moderate to severe periodontitis in control group were significantly lower compared to those in MCI group (17 cases with 43.6% vs. 23 cases with 74.2%, χ²=6.61, P=0.010), and the OR of moderate to severe periodontitis adjusted by age and educational background was 3.00 (95%CI: 1.01-8.86, P=0.048). Compared with the grading (χ²=5.56, P=0.062) of periodontitis, staging had a greater impact on MCI (χ²=7.69, P=0.041), moreover the proportion of MCI in stage Ⅰ grade A periodontitis was significantly lower than any other type of periodontitis (χ²=13.86, P=0.036). In addition, less presence of deep periodontal pockets [probing depth (PD)≥6 mm] (17.9% vs. 41.9%, χ²=4.87, P=0.027), fewer number of PD≥4 mm (6.48±6.70 vs. 11.03±8.91, t=-2.44, P=0.017), lower plaque index (1.42±0.56 vs. 1.68±0.57, t=-1.91, P=0.059) and gingival index (1.68±0.29 vs. 1.96±0.30, t=-3.93, P<0.001) were in the control group than in the MCI group. However, there were no significant differences between the two groups in the levels of serum inflammatory factors, such as hs-CRP, IL-1β, IL-6 and TNF-α (P>0.05). Conclusions: It appears a strong correlation between moderate to severe periodontitis and the incidence of MCI in middle-aged and elderly people. Moreover, deep and increased number of periodontal pockets, poor oral hygiene, and severe gingival inflammation can be potentially associated risk factors for MCI.

Abstract
OBJECTIVE To observe the effect on motor function, spasticity degree, muscle strength and the relevant parameters of three-dimensional gait analysis in the patients with post-stroke spasticity in the lower limbs treated with the combined therapy of electroacupuncture (EA) and muscle electricity biofeedback or the simple muscle electricity biofeedback therapy on the base of rehabilitation medicine. METHODS A total of 60 patients with post-stroke spasticity in the lower limbs were randomized into an EA + biofeedback group, a biofeedback group and a rehabilitation group, 20 cases in each one. In the rehabilitation group, the basic rehabilitation training was provided, 45 min each time. In the biofeedback group, on the base of the treatment as the rehabilitation group, the biofeedback therapy was added, 30 min each time. In the EA + biofeedback group, besides the treatment as the biofeedback group, acupuncture was supplemented at Futu (ST 32), Liangqiu (ST 34), Zusanli (ST 36) and Fenglong (ST 40), etc, and EA was applid at Zusanli (ST 36) and Taichong (LR 3) with continuous wave and 5 Hz in frequency. In each group, the treatment was given once daily, 5 times a week, for 6 weeks totally. Separately, before and after treatment, the score of Fugle-Meyer assessment (FMA), the score of clinical spasticity index (CSI) in the lower limbs and the strength of the anterior tibial muscle on the affected side were assessed, and the spatial-temporal parameters (step frequency and steep speed) in the three-dimensional gait analysis and the kinematic parameters (maximum dorsal flexion and maximum plantar flexion of ankle joint on the affected side) were measured in the patients of three groups. RESULTS After treatment, FMA score was increased as compared with that before treatment in all of three groups (P<0.05). FMA score in the EA + biofeedback group and the biofeedback group was higher than the rehabilitation group respectively (P<0.05). CSI score in the EA + biofeedback group and the biofeedback group was lower than that before treatment respectively (P<0.05), and lower than the rehabilitation group (P<0.05). After treatment, the step frequency and speed were all improved and the angles of maximum dorsal flexion and maximum plantar flexion of ankle joint on the affected side were all increased as compared with those before treatment in the patients of three groups separately (P<0.05). The step frequency and speed, as well as the angles of maximum dorsal flexion and maximum plantar flexion of ankle joint on the affected side in either the EA + biofeedback group or the biofeedback group were all higher than the rehabilitation group (P<0.05), and the step speed in the EA + biofeedback group was higher than the biofeedback group (P<0.05). After treatment, the strength of the anterior tibial muscle on the affected side was increased as compared with that before treatment in the patients of each group (P<0.05); and the strength of the anterior tibial muscle in the EA + biofeedback group and the biofeedback group was larger than the rehabilitation group (P<0.05). CONCLUSION On the base of rehabilitation treatment, the combined regimen of EA and muscle electricity biofeedback therapy and the simple muscle electricity biofeedback therapy all effectively strengthen the motor functions and reduce spasticity as well as improve step frequency, step speed and the range of motion of ankle joint in the patients with post-stroke spasticity in the lower limbs. Regarding the gait improvement, the combined regimen of EA and muscle electricity biofeedback is better than the simple muscle electricity biofeedback.

Abstract
OBJECTIVE This study investigated the effects of transcranial direct current stimulation (tDCS) combined with conventional swallowing training on the swallowing function in brainstem stroke patients with cricopharyngeal muscle dysfunction (CPD). METHODS Twenty-eight brainstem stroke patients with CPD were assigned randomly to an anodal tDCS group or a sham tDCS group. The patients received anodal tDCS or sham tDCS over the bilateral oesophageal cortical area combined with simultaneous catheter balloon dilatation and conventional swallowing therapy for 20 days. Swallowing function was assessed using the functional oral intake scale (FOIS) and the functional dysphagia scale (FDS) and by measuring the pharyngoesophageal Segment Opening (PESO) before and immediately after the intervention. RESULTS Both groups showed a significant improvement in the FDS, FOIS and PESO scores immediately after the intervention (all p < .005). However, compared with the sham stimulation group, the anodal tDCS group showed greater improvements in the FDS, FOIS and PESO scores immediately after the intervention (all p < .005). CONCLUSION The bihemispheric anodal tDCS combined with simultaneous catheter balloon dilatation and conventional swallowing therapy effectively improves the swallowing function in patients with CPD caused by a brainstem stroke. tDCS may be an effective adjuvant therapy in CPD rehabilitation.

Abstract
Wu Jinshou()[(1785-1795)-(1844-1851)]once wanted to take the imperial examination, but in late Qing Dynasty, under the depressed situation of economics and politics, he was trapped in countryside as many lower intellectuals, and chose medicine as another way to earn a living. In fact, he was both a doctor and a literatus. He kept friends with scholars, such as Zhang Tingji, Yao Wentian, Lu Changchun, Wei Guangfu, and scholar-physicians like Chen XIshu, Lu zeng and also Xu Jin's family, famous doctors at that time. He changed status Flexibly. To some extent, he represented the basic appearance of the traditional Chinese practitioner. In Daoguang 11 years(1831), Wu Jinshou published Medincal Cases Records of Three physicians(《》), Yi Xiao Mi Chuan(《》), Wen Re Zhui Yan(《》). This naturally have business purpose and was market-oriented. He had influenced on the spread of Wuzhong(the name of Suzhou and its surrounding area in Ming and Qing Dynasty) medical books, and provided some topics to the study of the Wenbing academic history.

Abstract
Background The effectiveness of meditative movement (tai chi, yoga, and qigong) on COPD remained unclear. We undertook a systematic review and meta-analysis to determine the effectiveness of meditative movement on COPD patients. Methods We searched PubMed, Web of Science, EMBASE, and the Cochrane Center Register of Controlled Trials for relevant studies. The methods of standard meta-analysis were utilized for identifying relevant researches (until August 2017), quality appraisal, and synthesis. The primary outcomes were the 6-minute walking distance (6MWD), lung function, and dyspnea levels. Results Sixteen studies involving 1,176 COPD patients were included. When comparing with the control group, the 6MWD was significantly enhanced in the treatment group (3 months: mean difference [MD]=25.40 m, 95% CI: 16.25 to 34.54; 6 months: MD=35.75 m, 95% CI: 22.23 to 49.27), as well as functions on forced expiratory volume in 1 s (FEV1) (3 months: MD=0.1L, 95% CI: 0.02 to 0.18; 6 months: MD=0.18L, 95% CI: 0.1 to 0.26), and FEV1 % predicted (3 months: 4L, 95% CI: 2.7 to 5.31; 6 months: MD=4.8L, 95% CI: 2.56 to 7.07). Quality of life for the group doing meditative movement was better than the control group based on the Chronic Respiratory Disease Questionnaire dyspnea score (MD=0.9 units, 95% CI: 0.51 to 1.29) and fatigue score (MD=0.75 units, 95% CI: 0.42 to 1.09) and the total score (MD=1.92 units, 95% CI: 0.54 to 3.31). Conclusion Meditative movement may have the potential to enhance lung function and physical activity in COPD patients. More large-scale, well-designed, multicenter, randomized controlled trials should be launched to evaluate the long-range effects of meditative movement.

Abstract
In this work, we demonstrate a novel carrier transporting combination made of tungsten trioxide (WO3) nanomaterials and Cs2CO3/PCBM buffer bilayer for the fabrication of perovskite solar cells (PSCs). Two different types of WO3, including nanoparticles and nanorods, were prepared by sol-gel process and hydrothermal method, respectively. Cs2CO3/PCBM buffer bilayer was inserted between WO3 and perovskite layers to improve charge transfer efficiency and formation of pinhole-free perovskite layer. Besides, the leakage current of the devices containing Cs2CO3/PCBM buffer bilayer was significantly suppressed. The optimized device based on WO3 nanoparticles and Cs2CO3/PCBM bilayer showed an open-circuit voltage of 0.84 V, a short-circuit current density of 20.40 mA/cm2, a fill factor of 0.61, and a power conversion efficiency of 10.49 %, which were significantly higher than those of PSCs without Cs2CO3/PCBM buffer bilayer. The results revealed that the combination of WO3 nanomaterials and Cs2CO3/PCBM bilayer provides an effective solution for improving performances of PSCs.

Abstract
The female healer is a special community in traditional Chinese medical professionals. Since the Song-Yuan Dynasties, although the literati class holding the social voices and the male healers acting as medical orthodoxy were always suspicious of the female healers' behaviors and their medical morality, and tarnished their images through all kinds of media. Meanwhile, the female healers were still badly needed on the account of recognition of distinction between sexes between both sexes due to the rising of neo-Confucianism. An excellent female healer could still earn wide respect from the society. Gu Dehua was a famous female healer from Wuzhong in the Qing Dynasty's Daoguang-Xianfeng period. By investigating Gu Delua's family conditions, deeds and works, and her career, the community of the female healers in the Ming-Qing Dynasties can be thus understood.

Abstract
OBJECTIVES Amelogenins are proposed to be responsible for enamel matrix derivative (EMD)-induced periodontal regeneration; however, heterogeneity of amelogenins makes it challenging to purify the full-length proteins. This study has been carried out to express and purify a recombinant full-length human amelogenin protein (rHhAm175) in the eukaryotic yeast Pichia pastoris, and further compare biological responses of human periodontal ligament fibroblasts (PDLFs) to rHhAm175 and porcine EMD (pEMD). MATERIALS AND METHODS Human cDNA encoding a 175-amino acid amelogenin was subcloned into the pPIC3.5K vector. The rHhAm175 expressed in P. pastoris GS115 (Mut+) was purified and characterized. We examined cell attachment, migration and proliferation responses of human PDLFs to rHhAm175 and pEMD respectively, and characterized associated changes of proliferation-related intracellular signalling molecules, including extracellular signal response kinase (ERK) and Akt kinases/protein kinase B (Akt/PKB) kinases. RESULTS The purified rHhAm175 was confirmed to be molecular mass 22 021.13 Da, phosphorylated human amelogenin, and alone significantly promoted proliferation and migration of human PDLFs to an extent comparable to that of pEMD. Cell attachment was increased over the first 60 min incubation with rHhAm175 or pEMD. Both rHhAm175 and pEMD induced PDLF mitogenesis via extracellular signal response kinase (ERK1/2), but not by Akt kinases/protein kinase B (Akt/PKB). CONCLUSIONS rHhAm175 modulated cell activities of human PDLFs, to a comparable extent as porcine EMD. These data suggest that rHhAm175 might be used to induce periodontal tissue regeneration.
