RESUMO
The extraction of wisdom teeth with mandibular impact frequently results in complications including damage to the inferior alveolar nerve (IAN) and malformations of the bone. The objective of this research endeavour was to assess the efficacy of low-level laser therapy and concentrated growth factor (CGF) in facilitating nerve recovery and wound healing in such instances. A total of thirty-one patients (mean age 27.52 ± 5.79 years) who presented with IAN injury after extraction were randomly assigned to one of three groups: control group (which received oral mecobalamin), CGF group (which received CGF gel applied to the extraction sockets) and laser group (which received low-level lasers (808 nm, 30 mW, 10 J/cm2 )) at the extraction site. Patients' recovery from IAN paresthesia was evaluated seven times over the course of 14 days utilizing visual analogue scale (VAS) and the pinprick test (PP). At multiple intervals following surgery, periodontal probing and bone level measurements were utilized to assess the recovery of both soft and hard tissues. The findings revealed that, compared with the control group, both the CGF and laser treatment groups exhibited a markedly greater improvement in VAS scores and wound healing of soft tissues, as well as in PP results (p < 0.001), indicating enhanced wound healing processes. Despite these improvements, there was no significant difference in wound healing outcomes between the CGF and laser groups. Notably, the CGF group showed a statistically significant improvement in healing bone defects at 30 and 90 days post-treatment compared with the control group (p = 0.003 and p = 0.004, respectively), underscoring its effectiveness in bone healing as a critical aspect of the overall wound healing process. However, in terms of other wound healing comparisons, no significant differences were observed. CGF and laser therapy significantly enhanced the healing of wounds, including soft tissue and bone recovery, in addition to accelerating the recovery of IAN injuries following mandibular wisdom tooth extraction. Although both treatments were equally effective in nerve recovery, CGF notably excelled in promoting bone healing, suggesting its pivotal role in comprehensive wound healing. This highlights that both CGF and laser therapy are viable options for not only nerve recovery but also for overall wound healing in such dental procedures.

BACKGROUND: Probiotics comprise effective feed additives that can replace antibiotics in animal livestock production. However, mono-strain probiotics appear less effective because of their instability. Therefore, the present study aimed to investigate dietary supplementation with compound probiotics (CPP) on growth performance, diarrhea rate and intestinal mucosal barrier, as well as the possible molecular mechanism, in chicks. In total, 360 1-day-old chicks of the Hy-Line Brown Chicks were randomly divided into the control group (CON, basal diet), chlortetracycline group (500 mg kg-1 CTC) and compound probiotics group (1000 mg kg-1 CPP, consisting of Bacillus subtilis, Bacillus licheniformis, Enterococcus faecium and yeast). The experiment period was 56 days. RESULTS: The results showed that, in comparison with the CON group, CPP significantly increased the average daily feed intake and average daily gain of chicks and reduced diarrhea (P < 0.05). The probiotic group exhibited increased immune organ (i.e. spleen and thymus) mass and increased levels of serum immunoglobulin (Ig)A, IgM and IgG (P < 0.05) compared to the CTC group. In addition, the jejunal mass and morphology were improved in the probiotic group (P < 0.05). Moreover, CPP reinforced jejunal barrier function, as indicated by increased transepithelial electrical resistance, protein expression of occludin and claudin-1, and diamine oxidase levels in the jejunum (P < 0.05). Likewise, enhanced fluorescence signals of proliferating cell nuclear antigen-labeled mitotic cells and villin-labeled absorptive cells in the jejunum (P < 0.05) suggested that CPP promoted intestinal stem cells activity. Mechanistically, the Wnt/ß-catenin signaling pathway, including ß-catenin, TCF4, c-Myc, cyclin D1 and Lgr5, was amplified in the jejunum by CPP addition (P < 0.05). CONCLUSION: The present study demonstrated that dietary supplementation with CPP reinforced the jejunal epithelial integrity by activating Wnt/ß-catenin signaling and enhanced immune function in chicks. © 2023 Society of Chemical Industry.

OBJECTIVE: To explore the effect of Kuanxiong Aerosol (KXA) on isoproterenol (ISO)-induced myocardial injury in rat models. METHODS: Totally 24 rats were radomly divided into control, ISO, KXA low-dose and high-dose groups according to the randomized block design method, and were administered by intragastric administration for 10 consecutive days, and on the 9th and 10th days, rats were injected with ISO for 2 consecutive days to construct an acute myocardial ischemia model to evaluate the improvement of myocardial ischemia by KXA. In addition, the diastolic effect of KXA on rat thoracic aorta and its regulation of ion channels were tested by in vitro vascular tension test. The influence of KXA on the expression of calcium-CaM-dependent protein kinase II (CaMK II)/extracellular regulated protein kinases (ERK) signaling pathway has also been tested. RESULTS: KXA significantly reduced the ISO-induced increase in ST-segment, interventricular septal thickness, cardiac mass index and cardiac tissue pathological changes in rats. Moreover, the relaxation of isolated thoracic arterial rings that had been precontracted using norepinephrine (NE) or potassium chloride (KCl) was increased after KXA treatment in an endothelium-independent manner, and was attenuated by preincubation with verapamil, but not with tetraethylammonium chloride, 4-aminopyridine, glibenclamide, or barium chloride. KXA pretreatment attenuated vasoconstriction induced by CaCl2 in Ca2+-free solutions containing K+ or NE. In addition, KXA pretreatment inhibited accumulation of Ca2+ in A7r5 cells mediated by KCl and NE and significantly decreased p-CaMK II and p-ERK levels. CONCLUSION: KXA may inhibit influx and release of calcium and activate the CaMK II/ERK signaling pathway to produce vasodilatory effects, thereby improving myocardial injury.

Objective: To explore the safety and short-term efficacy of venetoclax combined with azacitidine (Ven+AZA) in previously untreated patients unfit for standard chemotherapy and patients with relapsed/refractory (R/R) acute myeloid leukemia (AML) in China. Methods: A retrospective study was conducted in 60 previously untreated patients unfit for standard chemotherapy and patients with R/R AML who received Ven+ AZA (venetoclax, 100 mg D1, 200 mg D2, 400 mg D3-28; azacitidine, 75 mg/m(2) D1- 7) at the Peking University Institute of Hematology from June 1, 2019 to May 31, 2021. The incidence of adverse events, complete remission (CR) /CR with incomplete hematological recovery (CRi) rate, objective remission rate (ORR) , and minimal residual disease (MRD) status in patients with different risk stratification and gene subtypes were analyzed. Results: The median age of the patients was 54 (18-77) years, 33 (55.0%) were males, and the median follow-up time was 4.8 (1.4-26.3) months. Among the 60 patients, 24 (40.0%) were previously untreated patients unfit for standard chemotherapy, and 36 (60.0%) were R/R patients. The median mumber cycles of Ven+AZA in the two groups were both 1 (1-5) . According to the prognostic risk stratification of the National Comprehensive Cancer Network, it was divided into 8 cases of favorable-risk, 2 cases of intermediate risk, and 14 cases of poor-risk. In previously untreated patients unfit for standard chemotherapy, after the first cycle of Ven+AZA, 17/24 (70.8%) cases achieved CR/CRi, 3/24 (12.5%) achieved partial remission (PR) , and the ORR was 83.3%. Among them, nine patients received a second cycle chemotherapy and two received a third cycle. Among CR/CRi patients, 8/17 (47.1%) achieved MRD negativity after two cycles of therapy. In the R/R group, after the first cycle of Ven+AZA, 21/36 (58.3%) cases achieved CR/CRi (7/21 achieved MRD negativity) , 3 achieved PR, and the ORR was 66.7%. Among R/R patients, 12 were treated for more than two cycles. There were no new CR/CRi patients after the second treatment cycle, and 14 cases (66.7%) achieved MRD negativity. According to the time from CR to hematological recurrence, the R/R group was divided into 12 cases in the favorable-risk group (CR to hematological recurrence ≥18 months) and 24 in the poor-risk group (CR to hematological recurrence<18 months, no remission after one cycle of therapy, and no remission after two or more cycles of therapy) . Eleven of 24 (45.8%) cases achieved CR/CRi after one cycle of Ven+AZA in the poor-risk R/R group, and 10 of 12 (83.3%) achieved CR/CRi in the favorable-risk R/R group, which was significantly superior to the poor-risk group (P=0.031) . After one cycle of treatment, 13 patients with IDH1/2 mutations and 4 that were TP53-positive all achieved CR/CRi. The CR/CRi rate of 18 patients with NPM1 mutations was 77.8%. Five patients with RUNX1-RUNX1T1 combined with KIT D816 mutation (two initial diagnoses and three recurrences) had no remission. Ven+ AZA was tolerable for AML patients. Conclusion: Ven+AZA has acceptable safety in previously untreated patients unfit for standard chemotherapy, patients with R/R AML can achieve a high response rate, and some patients can achieve MRD negativity. It is also effective in NPM1-, IDH1/IDH2-, and TP53-positive patients. The long-term efficacy remains to be observed.

Objective: To observe the anti-inflammatory effect, as well as the effect on the expression of microtubule-associated protein light chain 3B (LC3B) and Beclin-1 of herbal cake-partitioned moxibustion in rats with experimental autoimmune thyroiditis (EAT). Methods: Female Sprague-Dawley rats were randomly divided into a normal group and a modeling group. The EAT rat model was prepared by a combination of antigen immunization plus iodine agent induction. After the model was prepared, rats in the modeling group were randomly and equally divided into a model group and a herbal cake-partitioned moxibustion group. In the herbal cake-partitioned moxibustion group, moxibustion was alternately applied to two groups of points [Dazhui (GV14)-Mingmen (GV4) and Tiantu (CV22)-Guanyuan (CV4)], and the treatment continued for 30 d. Rats in the normal and model groups were only fixed identically without intervention. Histopathological manifestations of thyroid glands were observed by hematoxylin-eosin staining; the concentrations of thyroid peroxidase antibodies (TPOAb), thyroglobulin antibodies (TGAb), interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were detected by enzyme-linked immunosorbent assay; real-time fluorescence quantitative polymerase chain reaction and immunohistochemistry were used to detect the mRNA and protein expression of autophagy-related factors LC3B and Beclin-1 in thyroid tissue. Results: There were massive follicular destruction, lymphocytic infiltration, and interstitial fibrous tissue hyperplasia of the thyroid glands in the model group. Some follicles of the thyroid glands were destroyed with few lymphocyte infiltrations and fibrous tissue hyperplasia in the moxibustion group. Compared with the normal group, the concentrations of serum TPOAb, TGAb, IL-1β, IL-6, and TNF-α were increased in the model rats (P<0.05); the mRNA and protein expression levels of LC3B and Beclin-1 in thyroid tissue were reduced in the model group (P<0.05). Compared with the model group, the concentrations of serum TPOAb, TGAb, IL-1β, IL-6, and TNF-α were reduced in the herbal cake-partitioned moxibustion group (P<0.05); the mRNA and protein expression levels of LC3B and Beclin-1 in thyroid tissue were increased in the herbal cake-partitioned moxibustion group (P<0.05). The mRNA and protein expression of LC3B and Beclin-1 in thyroid tissue was negatively correlated with the serum levels of TPOAb and TGAb.Conclusion: Herbal cake-partitioned moxibustion reduces the inflammatory response in the thyroid glands of EAT rats and lowers the levels of serum TPOAb and TGAb. This may be related to the regulation of mRNA and protein expression of the autophagy-associated factors LC3B and Beclin-1 in rat thyroid tissue.
RESUMO
Geographical origin is an important factor affecting the quality of traditional Chinese medicine. In this paper, the identification of geographical origin of Gastrodia elata was performed by using excitation-emission matrix fluorescence and chemometric methods. Firstly, excitation-emission matrix (EEM) fluorescence spectra of Gastrodia elata samples from different geographical origins were obtained. And then three chemometric methods, including multilinear partial least squares discriminant analysis (N-PLS-DA), unfold partial least squares discriminant analysis (U-PLS-DA), and k-nearest neighbor (kNN) method, were applied to build discriminant models. Finally, 45 Gastrodia elata samples could be differentiated from each other by these classification models according to their geographical origins. The results showed that all models obtained good classification results. Compared with the N-PLS-DA and U-PLS-DA, kNN got more accurate and reliable classification results and could identify Gastrodia elata samples from different geographical origins with 100% accuracy on the training and test set. Therefore, the proposed method was available for easily and quickly distinguishing the geographical origin of Gastrodia elata, which can be considered as a promising alternative method for determining the geographic origin of other traditional Chinese medicines.

RESUMO
Objective:To evaluate the clinical efficacy and safety of Longmu Zhuanggu granule for the treatment of children recurrent respiratory infection due to lung-spleen Qi deficiency. Method:This multicenter stratified, block-randomized, double-blind, double-dummy, positive drug (pidotimod granule) parallel controlled, and non-inferiority trail intended to included 240 children patients and divided them into the experimental group (<italic>n</italic>=120) and the control group (<italic>n</italic>=120) at the ratio of 1∶1. Patients in both groups were treated for eight successive weeks and followed up for 12 months. The cure rates, numbers of respiratory infections, average courses of disease, curative effects of traditional Chinese medicine (TCM) syndrome, curative effects of individual symptoms, curative effects of immune indexes, and safety indexes between the two groups were observed and compared. Result:A total of 237 subjects were collected from 10 research centers, including 119 cases in the control group and 118 in the experimental group. There were 236 cases enrolled into the full analysis set (FAS), 210 into the per-protocol set (PPS), and 236 into the safety set (SS). The baseline data of the two groups were not significantly different from each other, indicating that they were comparable. The cure rates of the experimental group and control group were 75.21% (88/117) and 73.95%(88/119), respectively, with the 95% confidence interval (CI) of difference between the two groups being 1.26% (-9.85%,12.37%) for FAS and 3.81% (-6.28%,13.90%) for PPS. The 95% CI fell within the 10% non-inferiority margin, implying that non-infertility test of the cure rate in the treatment of endpoint disease was valid, and the conclusions of FAS and PPS analysis were consistent. There was no significant difference in the number or course of upper respiratory infection, bronchitis, and pneumonia. The difference in curative effects of TCM syndrome between the two groups after four weeks of treatment was not remarkable. After eight weeks of treatment, the total effective rate of the experimental group was 84.62%(99/117), statistically higher than 78.15%(93/119) of the control group(<italic>χ</italic><sup>2</sup>=-3.26,<italic>P</italic><0.05). There were no significant differences in the disappearance rates of individual symptoms between the two groups after four weeks of treatment. After eight weeks of treatment, the experimental group and control group exhibited the disappearance rates of 67.50%(54/80) and 47.37%(36/76) for shortness of breath and laziness to speak, 75.00%(54/72) and 53.33%(40/75) for poor appetite, 54.55%(60/110) and 37.84%(42/111) for hyperhidrosis, respectively, with obviously better outcomes observed in the experimental group (<italic>P</italic><0.05,<italic>P</italic><0.01). The inter-group comparison revealed significant differences in immune indexes after eight weeks of treatment. As demonstrated by comparison with the situations before treatment, IgA, IgG, IgM, and CD4 did not change significantly after treatment. Except for CD8 in the experimental group (<italic>P</italic><0.05), there was no significant difference in other immune indexes before and after treatment There was no significant difference in the incidence of adverse reactions. Conclusion:Longmu Zhuanggu granule is not inferior to pidomod granule in the treatment of children recurrent respiratory infection due to lung-spleen Qi deficiency, and it exhibits good safety, implying its promising clinical application value.

Xuezhikang (XZK), an extract of Chinese red yeast rice, is recommended as an optimal choice for patients with coronary heart disease (CHD) with markedly elevated triglyceride (TG) levels. This study was designed to compare the hypotriglyceridemic effects between XZK and simvastatin. The role of apolipoprotein A5 (apoA5), a key regulator of TG metabolism and a target gene of peroxisome proliferator-activated receptor α (PPARα), was to be identified in XZK-related hypotriglyceridemic actions. For these goals, hypertriglyceridemia of rats was induced by a high-fructose diet. In order to investigate the hypotriglyceridemic effects of XZK and simvastatin on these animals based on an equivalent low-density lipoprotein cholesterol (LDL-C) lowering power, we titrated their doses (XZK 80 mg/kg/d versus simvastatin 1 mg/kg/d) according to plasma LDL-C reduction of rats. Similarly, we titrated the target doses of the two agents (XZK 500 µg/ml versus simvastatin 10 µM) according to hepatocyte LDL receptor expressions, and then compared the effects of the two agents on TG and apoA5 of hepatocytes in vitro. Our results showed that XZK (80 mg/kg/d) had higher hypotriglyceridemic performance than simvastatin (1 mg/kg/d) on these animals albeit their equivalent LDL-C lowering power. Higher plasma apoA5 levels and hepatic apoA5 expressions were observed in rats treated with XZK (80 mg/kg/d) than simvastatin (1 mg/kg/d). Further, XZK (80 mg/kg/d) contributed to higher hepatic PPARα expressions of rats than simvastatin (1 mg/kg/d). Although the two agents led to an equivalent up-regulation of LDL receptors of hepatocytes, more TG reduction and apoA5 elevation were detected in hepatocytes treated with XZK (500 µg/ml) than simvastatin (10 µM). However, PPARα knockdown eliminated the above effects of XZK on hepatocytes. Therefore, our study indicates that XZK has greater hypotriglyceridemic performance than simvastatin in the setting of an equivalent LDL-C lowering power, which is attributed to more apoA5 up-regulation by this agent via the PPARα signaling pathway.

Objective To explore the effect of acupuncture-rehabilitation therapy on apoptosis and the expression of X-linked inhibitor of apoptosis protein (XIAP) and cleaved-caspase-9 in ischemic penumbra of rats with cerebral ischemia. Methods A total of 180 male Sprague-Dawley rats were randomly divided into sham operation group,model group,acupuncture group,rehabilitation group and acupunc-ture-rehabilitation therapy group.Each group was divided into three days,seven days and 14 days subgroups(n=12).The model was estab-lished with the modified Longa suture method. The model group and the sham operation group received no treatment. The acupuncture group received cluster needling of scalp acupuncture,the rehabilitation group received treadmill training,and the acupuncture-rehabilitation therapy group received both acupuncture and treadmill training.On the third,seventh and 14th days after modeling,the neurological func-tion was assessed with modified Neurological Severity Score(mNSS).The apoptosis was observed by TUNEL staining and the expression of XIAP and cleaved-caspase-9 protein was determined by Western blotting in cerebral ischemic penumbra,respectively.Results Compared with the model group,the mNSS scores decreased,the rate of apoptosis decreased,the expression of XIAP protein increased,and the expres-sion of cleaved-caspase-9 decreased in each treatment group at each time point(P<0.05).Compared with the other two treatment groups,the rate of apoptosis further decreased at each time points(P<0.05),the expression of XIAP protein further increased at each time points(P<0.05),the mNSS score further decreased(P<0.05)and the expression of cleaved-caspase-9 protein further decreased(P<0.05)seven days and 14 days after modeling in the acupuncture-rehabilitation therapy group.Conclusion Acupuncture and rehabilitation therapy could re-duce the neurological deficit in rats with cerebral ischemia,which was superior to the simple acupuncture treatment and rehabilitation train-ing.The mechanism may be related to th reduction of apoptosis by promoting XIAP protein expression and inhibiting caspase-9 protein acti-vation.
RESUMO
According to the records in Neijing (Internal Classic), this article discusses the relationship during the connotative evolution of mai (vessel) and jing (meridian) in the three aspects, named mai (vessels), the evolution from mai (vessel) to jing (meridian), and the connotation replacement of jing (meridian) with mai (vessel). The study results show that the connotation of Jingmai is originated from mai (vessel), but more enriched, which cannot be confused with each other. The recognition on the connotation of jingmai from mai (vessel) to jing (meridian) is the process of TCM understanding from concretization to abstraction, and from the entity to the concept. Jing (meridian) represents the law on the longitudinal and invariable running course of meridian, differenti from the perspective in western medicine in human body. This law results from the naive observation and is based on the rational summary and thinking, and it stands up the approval from practice. The description of jing (meridian) as mai (vessel) is just the superficial description of this term. In fact, its concept infers to the connotation of meridian.
