Retinal vein occlusion(RVO)is often accompanied by macular edema(ME), which is the main cause of visual impairment in patients. From the perspective of traditional Chinese medicine theory, the key pathogenesis lies in Qi stagnation and blood stasis, as well as internal retention of water and dampness, which is closely related to the dysfunction of internal organs such as liver depression and qi stagnation, spleen failure to function properly, and kidney deficiency with water retention. Although anti-vascular endothelial growth factor(VEGF)therapy has become the first-line treatment option for RVO-ME, some patients show a low response or no response to this therapy, resulting in recurrent ME. According to traditional Chinese medicine, such difficult-to-treat cases are often caused by long-term illness entering the meridians and the interplay of phlegm and blood stasis, or by deficiency of the body's vital energy and the lingering of pathogenic factors. Intervention should be carried out through therapeutic methods such as promoting blood circulation and diuresis, resolving phlegm and unblocking meridians, and strengthening the body's vital energy and eliminating pathogenic factors. At present, the pathogenesis of RVO-ME is not yet fully understood. Modern medicine believes that it may involve multiple factors such as retinal microstructure damage, abnormal blood flow and systemic diseases throughout the body, while traditional Chinese medicine emphasizes the overall connection between local lesions and the imbalance of Qi, blood, Yin and Yang throughout the body. This article systematically reviews the existing research achievements of traditional Chinese and Western medicine on RVO-ME, analyzes its possible high-risk factors, and provides a theoretical basis for formulating individualized treatment plans integrating the advantages of traditional Chinese and Western medicine for such patients.

This paper summarized the clinical experience of Professor LIU Shenlin in diagnosing and treating gastric cancer with the thinking of "prescription according to tendency". In this paper， the thinking of diagnosis and treatment for gastric cancer and medication skills were summarized into four dimensions： power， energy， chronology and situation. The diagnosis emphasizes the tendency of qi power， considering that the onset of gastric cancer primarily stems from the disorder of qi movement in zang-fu organs， and emphasizing the importance of regulating the liver and spleen qi to intercept the tendency of disease. It points out that dampness-phlegm-stasis-toxin is a crucial link leading to the metabolic imbalance of body energy， and Professor LIU adepts at using methods such as breaking up blood and expelling stasis， and clearing heat and resolving toxins to block the pathological chain reaction caused by energy imbalance and to restore the homeostasis of the organism. In the treatment process， according to the characteristics of gastric cancer staging and chronological evolution， we will explore the changes of the exuberance and weakness of healthy qi and pathogenic qi in the context of the chronologic tendency， and adjust the dosage of attacking and tonic medicines in different stages of the disease in order to balance and restore the body. The "situation" is in line with the state of consumptive disease in advanced gastric cancer， Professor LIU skillfully uses large doses of Huangqi （Astragalus mongholicus） with flexible combination of medicinals to replenish deficiencies， invigorate qi， and regulate blood vessels.

OBJECTIVE To investigate the effect of Jianpi Yangzheng(JPYZ)formula regulating tumor-associated macrophage(TAM)exosomes on anoikis in gastric cancer and its mechanism.METHODS TAM model was established by inducing human mononuclear THP-1 cells in vitro;M0,TAM and TAM+JPYZ formula exosomes were extracted by ultracentrifugation and co-incuba-ted with gastric cancer cells.Flow cytometry was used to detect the effect of exosomes in each group on anoikis in gastric cancer cells.A BALB/c transplanted tumor mouse model was constructed,and the expression level of apoptotic proteins in transplanted tumors was detected by Western blot.Label-free mass spectrometry proteomics and bioinformatics were used to analyze the differential proteins in gastric cancer cells before and after intervention;Western blot and qPCR experiments were used to detect the expression level of dif-ferential protein isocitrate dehydrogenase 1(IDH1),and ubiquitination experiments were used to detect the ubiquitination level of IDH1;kits were used to detect the levels of α-ketoglutarate(α-KG),NADPH/NADP+,glutathione(GSH/GSSG)and reactive oxy-gen species(ROS)content.RESULTS The anoikis rate of gastric cancer cells was reduced after TAM exosomes intervention(P<0.05,P<0.01),while it was significantly increased after TAM+JPYZ exosomes intervention(P<0.05,P<0.01).In the in vivo mouse experiment,the ratio of Cleaved Caspase-3/Caspase-3 in the tumor of the TAM exosome group was reduced(P<0.05),while the ra-tio was significantly increased after TAM+JPYZ exosome intervention(P<0.05).Proteomic analysis showed that IDH1 was significant-ly different after intervention,and was related to tricarboxylic acid cycle metabolism.Compared with the M0 group,the IDH1 ubiquiti-nation level of gastric cancer cells in the TAM group with exosome intervention was increased,the levels of α-KG,NADPH/NADP+and GSH/GSSG were significantly increased,and the ROS content was reduced(P<0.05),while TAM+JPYZ exosomes could reverse the above phenomenon.CONCLUSION JPYZ Formula can regulate TAM exosomes to cause ubiquitin degradation of IDH1 in gas-tric cancer cells,reduce the level of tricarboxylic acid cycle metabolism in gastric cancer cells,promote ROS accumulation,induce anoikis in gastric cancer,and thus inhibit the development of gastric cancer.

Objective:To compare the three effects of lidocaine in the prevention of general anesthesia in elderly patients.Methods:A total of 120 elderly patients (65-85 years old) underwent anesthesia with general anesthesia (ASA) Ⅰ ～ Ⅱ were randomly divided into thyrocricocentesis group (group H),throat surface anesthesia group (Group Y),intravenous injection group (group J) and control group (group D).Group H was injected with lidocaine for surface anesthesia;group Y used laryngeal spray for laryngeal sprayed lidocaine for surface anesthesia;group J was anesthetized induction of intravenous lidocaine to prevent intubation reaction;group D the control group was not treated with lidocaine.(SBP) and heart rate (HR) were measured before and after induction (T0),tracheal intubation (T1) and 1 (T2),3 (T3) and 5 min (T4),the changes of hemodynamics related indexes were compared.Results:Compared with the same group of T0,the SBP and HR of four groups of T1 moments were significantly decreased (P ＜0.05);In the other three groups,SBP was significantly increased at T2 and T3 (P ＜0.05),HR ofT2 was significantly increased (P ＜0.05);Compared with group D,SBP and HR in group H,Y and J were significantly different at T2,T3 and T4,he difference was statistically significant (P ＜0.05);but there was no statistically significant difference between the three groups (P＞ 0.05).Conclusion:The three ways of lidocaine can be used to prevent the general anesthesia reaction in elderly patients,the effect of three ways is parallel.However,cricothyroid membrane puncture increased the patient's pain,throat spray method increased the cumbersome operation and enhanced the cost of the patient,and intravenous injection method is simple and worthy of popularization and application in clinic.

Objective: To investigate the current bedtime routine among Chinese children less than 3 years of age and explore its dose-dependent association with sleep duration and sleep quality. Method: Healthy full-term born children aged 0-35 months were selected by stratified cluster random sampling method from 8 provinces in China following the "Hospital of Province-City-County" sampling technical route during 2012-2013.Brief Infant Sleep Questionnaire(BISQ) was used to assess sleep conditions of these children.Children′s personal and family information was obtained by Shanghai Children′s Medical Center Socio-demographic Questionnaire.Both of these questionnaires were filled in by parents. The effects of bedtime routine on children′s sleep duration and quality were analyzed by multivariate analysis of variance. Result: The children′s average age was(12±10) months(n=1 304), of whom 689 were males (52.8%, 689/1 304). There were 48.5%(632/1 304)of the parents reported that their children had not established regular sleep routines. There was a consistent dose-dependent association between bedtime routine and sleep duration, as well as other indicators for sleep quality (all P<0.05). The more regular the sleep routines, the longer the sleep duration, the earlier the children went to sleep, the shorter the sleep onset latency, the fewer the nighttime wakeup and the shorter the nighttime waking.The nighttime sleep duration was significantly longer for those with a bedtime routine 'every night’ than those who 'never’ had a bedtime routine (9.5(95%CI: 9.4-9.6)vs. 8.9(95%CI: 8.6-9.3)h, t=3.345, P=0.001). Compared with children who never had bedtime routines, children with regular bedtime routines had fewer night wakeup (1.3(95%CI: 1.2-1.4) vs. 2.4( 95%CI: 2.0-2.9), t=3.182, P=0.001) and shorter night waking duration(16.6(95%CI: 14.6-18.8) vs. 59.2 (95%CI: 47.0-72.7)min, t=6.383, P<0.01). Conclusion The percentage of children who have established regular bedtime routine is low in China. There is significant dose-dependent association between regular bedtime routine and sleep outcomes, especially sleep quality. The more regular the sleep routines, the better the sleep quality.

BACKGROUND:Studies have shown that umbilical cord blood stem cel transplantation promote the recovery of spinal cord injury, and electroacupuncture also can inhibit the proliferation of astrocytes to reduce damage to scar formation, suggesting that a combination of umbilical cord blood stem cel transplantation and electroacupuncture may play an important role in the treatment of acute spinal cord injuries. OBJECTIVE:To observe the influence of transplantation of human umbilical cord blood stem cels combined with electroacupuncture at theDu channel on expression of nerve growth factor and neurotrophin 3 in rats with spinal cord injuries. METHODS: Seventy-two female Sprague-Dawlay rats were randomly divided into control group, injury group, transplantation group and combined therapy group. In the control group, only an incision on the back was sutured;in the injury group, a piece of saline-infiltrated gelatin sponge, 1 mm×2 mm×2 mm, was placed into the transected spinal cord at T10 level; in the transplantation group and combined therapy group, a piece of gelatin sponged infiltrated in the suspension of human umbilical cord blood stem cels was placed into the transected spinal cord, respectively, and then, electroacupuncture stimulation at the Duchannel was performed in the combined therapy group at 1 hour after modeling. Specimens were taken at 7, 14, 28 days after modeling in each group, and then immunohistochemistry, western blot and real time-PCR methods were used to detect the expression of nerve growth factor and neurotrophin 3. RESULTS AND CONCLUSION:Compared with the transplantation group, the expression of nerve growth factor and neurotrophin 3 was lower in the injury group but higher in the combined therapy group at 7, 14, 28 days after modeling (P < 0.05). The results of western blot and real time-PCR were consistent with those of immunohistochemical detection. Findings show that human umbilical cord blood stem cel transplantation combined with electroacupuncture has a remarkable synergistic effect in the treatment of spinal cord injury that can significantly up-regulate the expression of nerve growth factor and neurotrophin 3, and contribute to injured spinal cord repair, regeneration and functional recovery after spinal cord injury.

BACKGROUND:At present, there are many researches about repairing articular cartilage defects. In particular, the microfracture technique has been widely used. OBJECTIVE:To observe recovery of knee joint motor function and morphological changes in tissue repair during articular cartilage defects with different directions (coronal position and sagittal position). METHODS:Articular cartilage fracture models with 2 mm-thick medial femoral condyles of rabbit knee joint were established. According to incision directions, models were assigned to coronal and sagittal groups. At 5, 10 and 20 weeks after model induction, general observation was performed. Specimens were sliced into paraffin sections, and subjected to hematoxylin-eosin staining and col agen staining. Tissue repair at the articular cartilage defects was observed using optical microscope and immunohistochemical method. After model induction, range of motion of rabbit joints was regularly examined in the two groups.RESULTS AND CONCLUSION:A white line was seen across the femoral condyles at defects in the two groups. Articular surface at defect repair was at the level of in situ cartilage, and reached a bone union. Knee joint treated by operation did not affect function. Under light microscope, partial reconstruction of subchondral bone was seen in the two groups, mainly fibrocartilage repair. The level of bony remodeling was lower than tidal line of adjacent in situ cartilage. Immunohistochemical method exhibited that type I col agen staining gradual y reduced at defects of specimens, but type II col agen staining gradual y increased. These results suggested that there was no significant difference in the recovery of motor function of knee joint and the repair of articular cartilage with different directions (coronal and sagittal position).
