The fundamental mechanism of gastrointestinal diseases is the imbalance between the attack factor and the protective factor of stomach mucous membrane. It can not outbreak if the protective factor is stronger than the attack factor; otherwise, it will. Attack and protective function inside the stomach are mediated by various factors. These related factors interaction constitutes a complicated network system. This kind of outbreak theories of imbalance in Western medicine is same as that, "The sense of right saves inside, the evil can't do" and "Evil is competing with right, all diseases occur", in Chinese medicine. So, it is the key which points to futher study the interaction between gastrointestinal attack factors and protective factors by traditional Chinese medicine, thus improving the clinical effect.

Objective To study the effect of Phenobarbital (PB) on experimental rats,observe the histological changes of immature brain and the expressions of apoptosis-related proteins Bcl-2 and Bax in neurons detected by immunohistochemistry,and to explore the influence and mechanism of PB on brain damage at therapeutic levels to immature brain maturation of rat in order to provide the theoretical and experimental base for clinic.Methods A total of 40 healthy 18-day-old Sprague-Dawley(SD) rats (male or female) were randomly assigned into 2 groups:normal saline (NS) treated as control group(20 cases),PB group(20 cases).Each group was further randomly divided into longterm(4 weeks) treated group and short-term(2 weeks) treated group(10 rats in each group).The rats in PB group received intragastricadministration with PB (30 mg/kg).The rats in control group were handled by injection of NS into stomach and abdomen according to 4 mL/kg.All performances were undertaken for twice every day.At the end of the therapeutic period,body and brain weight were measured when the rats were sacrificed.Histological studies on the tissues of frontal lobes and hippocampus were performed by Hematoxylin-Eosin(HE) staining and Nissl staining.Expressions of apoptosis-related proteins Bcl-2 and Bax in neurons were detected by immunohistochemistry.Results There were no significant differences in body and brain weights or histological studies index among control group as well as PB group before and after treatment for short term(P ＞0.05).Remarkable reduction of brain weight was only observed in immature rats exposed to PB compared to control group for long period,and significant neurodegeneration,neuronal necrosis were observed in immature rats exposed to PB compared to control group(all P ＜ 0.01).The expression of Bax protein in the frontal lobe increased significantly in immature rats receiving PB for long period comparing with control (P＜0.01).In contrast,expression of Bcl-2 protein did not change at therapeutic level.The ratio of Bax/Bcl-2 was obviously increased.Conclusions Chronic treatment with PB will result in significant neuronal apoptosis and necrosis and persistent cognitive impairment and brain damage to immature rates.Brain damage of PB at therapeutic level to immature brain may be irreversible.The significant expression of Bax protein in the frontal lobe and the high rate of Bax/Bcl-2 are probably the main reasons which cause brain weight decreasing and brain damage by PB in immature brain tissue.

In the new stage for intelligent manufacturing of traditional Chinese medicine(TCM) from pilot demonstration to in-depth application and comprehensive promotion, how to raise the degree of intelligence for the process quality control system has become the bottleneck of the development of TCM production process control technology. This article has sorted out 226 TCM intelligent manufacturing projects that have been approved by the national and provincial governments since the implementation of the "Made in China 2025" plan and 145 related pharmaceutical enterprises. Then, the patents applied by these pharmaceutical enterprises were thoroughly retrieved, and 135 patents in terms of intelligent quality control technology in the production process were found. The technical details about intelligent quality control at both the unit levels such as cultivation, processing of crude herbs, preparation pretreatment, pharmaceutical preparations, and the production workshop level were reviewed from three aspects, i.e., intelligent quality sensing, intelligent process cognition, and intelligent process control. The results showed that intelligent quality control technologies have been preliminarily applied to the whole process of TCM production. The intelligence control of the extraction and concentration processes and the intelligent sensing of critical quality attributes are currently the focus of pharmaceutical enterprises. However, there is a lack of process cognitive patent technology for the TCM manufacturing process, which fails to meet the requirements of closed-loop integration of intelligent sensing and intelligent control technologies. It is suggested that in the future, with the help of artificial intelligence and machine learning methods, the process cognitive bottleneck of TCM production can be overcome, and the holistic quality formation mechanisms of TCM products can be elucidated. Moreover, key technologies for system integration and intelligent equipment are expected to be innovated and accelerated to enhance the quality uniformity and manufacturing reliability of TCM.

OBJECTIVE: To verify the consistency between the digital manufacturing simple intraoral Gothic arch-tracing device and the traditional intraoral Gothic arch-tracing device in determining the centric relation of complete dentures restoration. METHODS: Ten outpatients with edentulous jaws were selec-ted, and the centric relation of the patients was determined by digital manufacturing of simple intraoral Gothic arch-tracing device (T1) and traditional intraoral Gothic arch-tracing device (T2); the difference of clinical operation time between the two methods was recorded; the upper and lower edentulous jaw plaster models were scanned with two kinds of centric relation, the Standard Triangle Language (STL) files imported into Geomagic studio software to apply the best fitting of multiple points of the both upper jaw models, the fitted STL files imported into the 3 shape viewer software, and the maximum position deviations of the vertical, labial (buccal) and lingual directions of the mandibular midline area and molar areas in T1 and T2 groups measured. During the clinical complete dentures try-in, we observed whether there was midline deviation in the mouth of T1 group and T2 group, and whether the occlusion of posterior teeth was stable or not. RESULTS: The mean time spent on determining the centric relation of T1 and T2 groups was (41.90±2.64) min, (57.50±2.37) min respectively. Paired t test was conducted in the two groups, P < 0.01 with significant statistical difference; The mean maximum position deviation between T1 group and T2 group of the midline mandibular region in labial lingual direction was (0.32±0.14) mm, that was (0.40±0.23) mm in vertical direction; the mean maximum position deviation of molar area in buccal lingual direction was (0.35±0.23) mm and that was (0.33±0.20) mm in vertical direction. In the vertical and horizontal directions, the maximum position deviation of mandibles between group T1 and group T2 was controlled within 0.5 mm. In the process of clinical complete dentures try-in, there was no deviation from the center line of dentures. There was not warping, swinging and other poor stability phenomena in T1 and T2 groups. CONCLUSION The digital manufacturing of simple intraoral Gothic arch-tracing device can be used to determine the centric relation of complete dentures, which can not only save time of clinical operation, but also ensure the accuracy of the centric relation.
