OBJECTIVE: To investigate the clinical effect of Kinesio Taping combined with electroacupuncture in the treatment of Bigliani typeⅠsubacromial impingement syndrome. METHODS: From January 2019 to June 2021, 82 cases with Bigliani typeⅠsubacromial impingement syndrome were selected and divided into treatment group and control group. Treatment group included 41 cases, 23 males and 18 females, aged from 20 to 52 years old, with an average of (39.31±5.80)years old. There were 12 cases on left shoulder and 29 cases on right shoulder. The course of disease was from 3.2 to 35.4 months. The treatment group was treated with Kinesio Taping and electroacupuncture. In control group, there were 41 cases, including 22 males and 19 females, aged from 19 to 53 years old with an average of (40.67±6.13) years old, 30 cases on right shoulder, 11 cases on left shoulder. The courses of disease was from 3.0 to 36.0 months. The control group was treated with simple shoulder electroacupuncture. Patients in both groups were treated with electroacupuncture 3 times a week for 3 weeks. After each electroacupuncture treatment in the treatment group, the Kinesio Taping was applied immediately and kept for 2 days. Before treatment, immediately after treatment, and after 1, 3, 8 weeks, the shoulder joint Constant-Murley score, pain visual analogue scale (VAS), and shoulder joint range of motion were used to evaluate the treatment effect. RESULTS: After 1 week of treatment, there was 1 patient in treatment group refused treatment due to hypersensitivity to Kinesio Taping, 1 patient in control group was allergic to the metal needle and refused treatment. And the other 80 patients completed all treatment. Immediately after treatment, and 1, 3, and 8 weeks after treatment, VAS of treatment group were (2.06±1.03), (2.74±1.66), (3.28±1.04), and (3.90±0.12) points, respectively. The Constant-Murley scores of shoulder joint were(86.41±3.52), (82.44±3.14), (80.46±2.54), (76.97±2.01) points. VAS of control group were(3.35±0.41), (3.08±0.92), (3.77±0.67), (3.96±1.04) points, and the Constant-Murley scores of the shoulder joint were(75.82±2.73), (74.72±1.53), (73.66±1.53), (70.68±1.95) points respectively. Immediately after treatment, VAS, Constant-Murley score, and shoulder range of motion between two groups were better than those of before treatment (P<0.05), and the difference was statistically significant between two groups after treatment (P<0.05). One week after treatment, VAS, Constant-Murley score, and shoulder joint range of motion between two groups were better than those of before treatment (P<0.05), but there was no significant difference in VAS between two groups (P>0.05). There were significant differences in the Constant-Murley score and shoulder range of motion between two groups (P<0.05). At 3 and 8 weeks after treatment, VAS, Constant-Murley score, and the range of motion of shoulder joints between two groups were better than those of before treatment (P<0.05), but there was no significant difference between two groups(P>0.05). CONCLUSION: The treatment for bigliani typeⅠsubacromial impingement syndrome with Kinesio Taping combined with electroacupuncture can reduce pain, effectively improve the function of shoulder joint. In addition, with Kinesio Taping protection when motion, the patients sports ability can be improved obviously, with good immediate effect, and no trauma. If the patients are willing to accept it, it would be an immediate and effective treatment.

Ferric ions release from iron-binding protein: Interaction between acrylamide and human serum transferrin and the underlying mechanisms of their binding.

Acrylamide (ACR) is a surprisingly common chemical due to its widespread use in industry and various other applications. However, its toxicity is a matter of grave concern for public health. Even worse, ACR is frequently detected in numerous fried or baked carbohydrate-rich foods due to the Maillard browning reaction. Herein, this study intends to delineate the underlying molecular mechanisms of Fe ions released from iron-binding protein transferrin (TF) after acrylamide binding by combining multiple methods, including multiple complementary spectroscopic techniques (UV-Vis, fluorescence, and circular dichroism spectroscopy), isothermal titration calorimetry, ICP-MS measurements, and modeling simulations. Results indicated that free Fe was released from TF only under high-dose ACR exposure (>100 µM). Acrylamide binding induced the loosening and unfolding of the backbone and polypeptide chain and destroyed the secondary structure of TF, thereby leading to protein misfolding and denaturation of TF and forming a larger size of TF agglomerates. Of which, H-binding and van der Waals force are the primary driving force during the binding interaction between ACR and TF. Further modeling simulations illustrated that ACR prefers to bind to the hinge region connecting the C-lobe and N-lobe, after that it attaches to the Fe binding sites of this protein, which is the cause of free Fe release from TF. Moreover, ACR interacted with the critical fluorophore residues (Tyr, Trp, and Phe) in the binding pocket, which might explain such a phenomenon of fluorescence sensitization. The two binding sites (Site 2 and Site 3) located around the Fe (III) ions with low-energy conformations are more suitable for ACR binding. Collectively, our study demonstrated that the loss of iron in TF caused by acrylamide-induced structural and conformational changes of transferrin.

Stone buildings exposed to natural environment inevitably subject to various factors. Among which, biodeterioration caused by bacteria, fungi, algae, lichen, and moss is widespread. The long-term cumulative effect of biodeterioration will lead to irreversible changes in the aesthetic characteristics, physical and chemical properties of stone buildings. Therefore, it is necessary to control the biodeterioration of stone buildings. Here, we summarized four traditional methods including heat shock treatments, laser and ultraviolet radiation, application of biocides, and presented typical examples. We analyzed several emerging techniques, such as synergistic effect of physical and chemical methods, plant extracts and nanomaterials biocides, and reviewed their advantages, disadvantages as well as applicability. Aiming to provide a reference for the research of biodeterioration prevention and conservation of stone buildings, we discussed the preventive methods for biodeterioration of stone building and the assessment methods to test the effects of such methods, and prospected the future research direction.

Emerging Benefits: Pathophysiological Functions and Target Drugs of the Sigma-1 Receptor in Neurodegenerative Diseases.

The sigma-1 receptor (Sig-1R) is encoded by the SIGMAR1 gene and is a nonopioid transmembrane receptor located in the mitochondrial-associated endoplasmic reticulum membrane (MAM). It helps to locate endoplasmic reticulum calcium channels, regulates calcium homeostasis, and acts as a molecular chaperone to control cell fate and participate in signal transduction. It plays an important role in protecting neurons through a variety of signaling pathways and participates in the regulation of cognition and motor behavior closely related to neurodegenerative diseases. Based on its neuroprotective effects, Sig-1R has now become a breakthrough target for alleviating Alzheimer's disease and other neurodegenerative diseases. This article reviews the most cutting-edge research on the function of Sig-1R under normal or pathologic conditions and target drugs of the sigma-1 receptor in neurodegenerative diseases.

Pharmacokinetics of FGF21-164 fusion protein in mice using UHPLC-MS/MS method / 药学学报

FGF21-164 is a fusion protein obtained by structural modification and coupling of endogenous FGF21. It is a candidate drug used in the treatment of glucose and lipid metabolic disorders caused by obesity. In this study, the candidate peptide mass spectrometry information of the protein hydrolyzed by trypsin was predicted by Skyline software and verified by high resolution mass spectrometry. The specific surrogate peptide (YLYTDDAQQTEAHLEIR) with the best mass response was selected after optimizing ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Under ESI positive ion mode, the parent ion m/z 689.3 with 3 charge and the product ion m/z 738.4 with single charge can be monitored. After dilution by PBS, the serum samples were denatured under 60 ℃ and alkylated to reduce the matrix effect, then incubated with trypsin at 37 ℃ for 2 h, to obtain the surrogate peptide. The chromatographic separation was carried out on an EclipsePlus C18 column (2.1 mm×50 mm, 1.8 μm) using aqueous solution containing 0.1% formic acid (phase A) and acetonitrile solution containing 0.1% formic acid (phase B). Finally, the concentration of FGF21-164 fusion protein in mouse serum was quantitatively analyzed by external standard method by monitoring the above ion pairs using triple quadrupole mass spectrometer. This method showed a good linearity in the range of 2.50-500 μg·mL-1 (r = 0.998 8), and was successfully applied to the pharmacokinetic study of FGF21-164 fusion protein in mice. This experiment was approved by the Experimental Animal Ethics Committee of Shanghai Institute of Materia Medica, Chinese Academy of Sciences (batch number: 20180004040450). Compared with the endogenous FGF21, the t1/2 of FGF21-164 fusion protein was prolonged from 0.5 h to 2.6 h, which is expected to prolong the therapeutic efficacy of this protein.

A randomized, multicenter and noninferiority study of amoxicillin plus berberine vs tetracycline plus furazolidone in quadruple therapy for Helicobacter pylori rescue treatment.

OBJECTIVE: Helicobacter pylori (H. pylori) infection is closely associated with gastric ulcers and gastric adenocarcinomas. We aimed to assess the efficacy and safety of a quadruple regimen with amoxicillin plus berberine vs tetracycline plus furazolidone in rescue therapy for H. pylori eradication. METHODS: We conducted a randomized, open-label, multicenter, noninferiority trial. Patients with previous treatment failures recruited from five centers were randomized (1:1) to receive a regimen with esomeprazole and bismuth plus either berberine and amoxicillin (the BA group) or tetracycline and furazolidone (the TF group) for 14 days. Their H. pylori infection status was confirmed 4-8 weeks after treatment. The primary outcome was the eradication rate. The secondary outcomes included the rates of symptom improvement, compliance, and adverse events. This study was registered at ClinicalTrials.gov (NCT03609892). RESULTS: Altogether 658 participants were consecutively enrolled. An intention-to-treat analysis demonstrated that the two regimens achieved a similar eradication rate (76.3% vs 77.5%; P = 0.781). The per-protocol analysis reached a similar result (81.5% vs 85.0%; P = 0.278). The eradication rate reached in the BA group was greater than the pre-established margin of noninferiority, at -10% (the lower bounds of the 95% CI were -7.66% and -9.43%, respectively). The rate of adverse events was lower for the BA group than the TF group (18.5% vs 26.1%, P = 0.024). Rates of compliance and symptom improvement were similar for the two therapies. CONCLUSION: The efficacy of both regimens in rescue treatment for H. pylori eradication was satisfactory, 14-day BA-based quadruple therapy is noninferior to the TF-based therapy.

Panax ginseng C.A. Meyer (Rg3) Ameliorates Gastric Precancerous Lesions in Atp4a-/- Mice via Inhibition of Glycolysis through PI3K/AKT/miRNA-21 Pathway.

Gastric cancer, one of the most common types of cancers, develops over a series of consecutive histopathological stages. As such, the analysis and research of the gastric precancerous lesions (GPLs) play an important role in preventing the occurrence of gastric cancer. Ginsenoside Rg3 (Rg3), an herbal medicine, plays an important role in the prevention and treatment of various cancers. Studies have demonstrated a correlation between glycolysis and gastric cancer progression. Herein, the aim of the present study was to clarify the potential role for glycolysis pathogenesis in Rg3-treated GPL in Atp4a-/- mice. The GPL mice model showed chronic gastritis, intestinal metaplasia, and more atypical hyperplasia in gastric mucosa. According to the results of HE and AB-PAS staining, it could be confirmed that GPL mice were obviously reversed by Rg3. Additionally, the increased protein levels of PI3K, AKT, mTOR, HIF-1α, LDHA, and HK-II, which are crucial factors for evaluating GPL in the aspect of glycolysis pathogenesis in the model group, were downregulated by Rg3. Meanwhile, the miRNA-21 expression was decreased and upregulated by Rg3. Furthermore, the increased gene levels of Bcl-2 and caspase-3 were attenuated in Rg3-treated GPL mice. In conclusion, the findings of this study imply that abnormal glycolysis in GPL mice was relieved by Rg3 via regulation of the expressions of PI3K, AKT, mTOR, HIF-1α, LDHA, HK-II, and miRNA-21. Rg3 is an effective supplement for GPL treatment and can be harnessed to inhibit proliferation and induce apoptosis of GPL cells.

Combination of flunarizine and transcutaneous supraorbital neurostimulation improves migraine prophylaxis.

OBJECTIVE: This study is aimed to access the efficacy and safety of combination therapy of flunarizine plus transcutaneous supraorbital neurostimulation (tSNS) compared with either flunarizine or tSNS alone for migraine prophylaxis. METHODS: Patients with episodic migraine were enrolled and randomized into 3 groups. Flunarizine 5 mg per day, or tSNS for 20 minutes daily or combination of both were prescribed consecutively for 3 months. The primary outcome measures were changes in migraine days and 50% responder rate of monthly migraine days. Secondary outcome measures were the changes in migraine intensity and intake of rescue medication. Finally, satisfaction to treatment and adverse effect were evaluated as well. RESULTS: A total of 154 were randomized and included in the analysis. After 3 months, the monthly migraine days were decreased in 3 groups and more significant in the combination group. The 50% responder rate was significantly higher (78.43%) in the combination therapy than monotherapy of flunarizine (46.15%) or tSNS (39.22%) alone. Greater reduction of migraine intensity and intake of rescue medication was observed in combination group. There was no difference of adverse events between flunarizine group and combination group (P = .89). CONCLUSION: Adding tSNS to flunarizine can improve the therapeutic efficacy of migraine prophylaxis without increasing the adverse effects. In addition, tSNS is effective and safe for migraine treatment and can be a valid option for migraineurs who are reluctant to take oral medications or for patients who experience a low-migraine frequency and/or intensity that prophylactic therapy is not indicated but desire to acquire medical intervention.

The structures of the new compounds were established based on detailed NMR and HRESIMS analysis, as well as from their ECD spectra. The absolute configuration of the known compound 1-deoxy-2α-hydroxynagilactone A (16) was confirmed by single-crystal X-ray diffraction. All of the isolates were tested for their cytotoxic activities against cancer cells. The results indicated that compounds 4 and 6, as well as several known compounds, displayed cytotoxicity against A2780 and HEY cancer cells. Among the new compounds, 2ß-hydroxynagilactone L (6) showed IC50 values of less than 2.5 µM against the two cell lines used. Furthermore, compound 6 induced autophagic flux in A2780 cells, as evidenced by an enhanced expression level of the autophagy marker phosphatidylethanolamine-modified microtubule-associated protein light-chain 3 (LC3-II) and increased mRFP-GFP-LC3 puncta. Also, compound 6 activated the c-Jun N-terminal kinase (JNK) pathway, while pretreatment with the JNK inhibitor SP600125 decreased compound 6-induced autophagy.

A new benzofuran derivative from Nicotiana tabacum.

A new benzofuran derivative, methyl 3-acetyl-7-hydroxy-6-methoxy-2-methylbenzofuran-4-carboxylate (1), and a known compound pyrrolezanthine (2), were isolated from leaves of Nicotiana tabacum. Compound 1 was elucidated by means of spectroscopic methods, as well as X-ray diffraction. Both compounds 1 and 2 exhibited moderate inhibitory activities on human cancer cell lines.

[Concentration of Nitrate in Main Anoxic Stage and PHA, TP Metabolism for Nitrogen and Phosphorus Removal in Single Sludge System with Continuous Flow].

Based on test results and mass balance, PHA, TP metabolic regularity was revealed under different nitrate nitrogen concentrations in main anoxic stage [c(NO3)] for nitrogen and phosphorus removal in single sludge system with continuous flow, then the effectiveness of using c(NO3) as control parameter was proved from the perspective of the reaction mechanism. During experiment period, the influent COD, total nitrogen (TN), and total phosphorus (TP) concentrations were stabilized at (285.78±18.19), (58.13±3.79), and(7.14±0.51) mg·L-1, respectively. The experiment was carried out under the condition that the c(NO3) values were 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0 mg·L-1 based on the feedback control structure using PLC automatic control system to control the nitrifying liquid flow with the water quality. The sludge load of COD was (0.253±0.071)kg·(kg·d)-1, the sludge load of TP in anaerobic stage was (0.006±0.001) kg·(kg·d)-1, the sludge load of TN in aerobic stage was (0.049±0.006) kg·(kg·d)-1, the hydraulic retention time (HRT) in bioreactor was 9h, the sludge recycle flow was 0.5, and the mixed liquor recycle was 1.0. The results showed that effect of c(NO3) value on PHA synthesis and storage rate in the ANS was conspicuous, and the percentage of PHA storage occupied 74% of COD removal when c(NO3) value was 2.5 mg·L-1.The impact of c(NO3) value on PHA degraded in the main anoxic stage was great, and the percentage of PHA degradation in the main anoxic stage occupied 55% of total PHA degradation when c(NO3) value was 2.5 mg·L-1. The phosphorus released in anaerobic stage changed along with increasing c(NO3), and the amount of phosphorus released obtained the maximum value 6.16 g·d-1 when c(NO3) value was 2.5 mg·L-1. In addition, under c(NO3) value of 2.5 mg·L-1, the amount of total phosphorus uptake and anoxic phosphorus uptake obtained the maximum values of 8.04 g·d-1 and 3.67 g·d-1, respectively. Then it was confirmed thatc(NO3) could serve as a run controlling parameter with the best value of 2.5 mg·L-1 from the perspective of PHA and TP metabolic mechanism.
