Preliminary study on the process and prognosis of 55 cases of esophageal stricture after circumferential endoscopic submucosal dissection / 中华消化杂志

Objective:To investigate the characteristics, process, and prognosis of esophageal stricture after circumferential endoscopic submucosal dissection (ESD), and to preliminarily analyze the prevention and treatment effects of simple dilation, stent placement, mucosal transplantation, and glucocorticoid (hereinafter referred to as hormone) application in esophageal stricture.Methods:From August 2017 to March 2022, at the First Affiliated Hospital of Zhengzhou University, the clinical and follow-up data of 55 patients who underwent circumferential ESD for early esophageal cancer and precancerous lesions were retrospectively analyzed. According to the prevention and treatment methods for esophageal stricture, the patients were divided into two groups: simple dilation group (23 cases) and combined dilation group (32 cases). The combined dilation group was divided into mucosal transplantation subgroup (9 cases), stent placement subgroup (14 cases), hormone application subgroup (7 cases), and bleomycin subgroup (2 cases, excluded from comparative analysis due to limited cases). Overall prognosis of patients was observed. Treatment efficacy, prognosis, and adverse events were compared among the simple dilation group, mucosal transplantation subgroup, stent placement subgroup, and hormone application subgroup. Independent samples t-test, chi-square test, and Fisher′s exact test were used for statistical analysis. Results:Among the 55 patients, the follow-up time was (894.1±417.7) days. Refractory esophageal stricture (total dilation times ≥ 5) occurred in 33 patients (60.0%). Fifty-two patients (94.5%) achieved clinical remission of the stricture. The total number of dilations was 5.8±4.0, and the average dysphagia-free period was (52.3±37.1) days. The dysphagia-free period of mucosal transplantation subgroup was longer than that of the simple dilation group, stent placement subgroup, and hormone application subgroup ((114.5±50.0) days vs. (40.9±20.0), (39.7±10.0), and (40.9±25.5) days, respectively), and the differences were statistically significant ( t=4.82, 3.77 and 3.14, P<0.001, =0.011, =0.009). There were no statistically significant differences between the simple dilation group and the mucosal transplantation subgroup, stent placement subgroup, and hormone application subgroup in the total number of dilations (6.8±4.8 vs. 3.0±2.5, 5.8±2.2, and 5.7±5.0), stricture remission rate (95.7%, 22/23 vs. 8/9, 13/14, and 7/7), and incidence of adverse events (17.4%, 4/23 vs. 5/9, 5/14, and 2/7; all P>0.05). Conclusions:Esophageal stricture formed after circumferential ESD shows the characteristics of recurrence and intractability. The over all number of dilations is high, and the average dysphagia-free period is short. Most patients can achieve clinical remission of the stricture after multiple times of endoscopic dilation treatment. However mucosal transplantation, stent placement, and hormone application cannot well intervene the natural process of esophageal stricture.

The correlation between the level of PLA 2R and the condition and prognosis of patients with primary membranous nephropathy / 中国医师杂志

Objective:To investigate the correlation between serum anti phospholipase A2 receptor (PLA 2R) antibody level and the condition and prognosis of patients with primary membranous nephropathy (PMN).Methods:61 patients who were diagnosed as PMN in the laboratory department of Jiangsu Province Hospital of Chinese Medicine from January 2017 to August 2019 were selected and divided into PLA 2R positive group (41 cases) and PLA 2R negative group (20 cases) according to the level of PLA 2R antibody. The gender, age and other general data of the two groups were collected, and the clinical pathological characteristics and prognosis of the two groups were analyzed. Spearman correlation was used to analyze the correlation between the level of PLA 2R antibody and the disease condition and treatment prognosis.Results:The levels of estimate glomerular filtration rate (eGFR), total protein (TP) and albumin (ALB) in PLA 2R positive group were lower than those in PLA 2R negative group, while the levels of 24-h urinary protein and IgG4 were higher in PLA 2R positive group than that in PLA 2R negative group ( P<0.05); Multivariate logistic regression analysis showed that 24-hour urinary protein was an independent risk factor for PLA 2R antibody level ( OR=2.242, P<0.05), while TP and ALB levels were protective factors ( OR=0.840, 0.674, P<0.05); The patients in both groups were followed up for one year by rechecking serological indexes. The complete remission rate and total remission rate of PLA 2R positive group were lower than those of PLA 2R negative group ( P<0.05); Spearman correlation analysis showed that the level of PLA 2R antibody was negatively correlated with the levels of TP, ALB, and prognosis of patients ( r=-0.642, -0.547, -0.357, P<0.05), and positively correlated with the level of 24-hour urinary protein ( r=0.347, P<0.05). PLA 2R in renal tissue of 61 patients was found to be positive in 63.93% (39/61). Conclusions:The level of PLA 2R antibody is closely related to serum albumin, TP, 24 h urinary protein and prognosis of patients with PMN.

Acupoint position and manipulation of needle knife treating shoulder bi syndrome / 中国针灸

With Jianyu (LI 15), Jianliao (TE 14) and Jianzhen (SI 9) for instance, the three acupoints used to treat shoulder bi syndrome by needle knife, and through traceability and researching constant structure, the acupoint position, insertion trace, manipulation and clinical significance of needle knife medicine were discussed. Accurate position is one of the characteristics of acupoints selection of needle knife medicine. As for the acupoints selection method, the mean of body surface localization is always used. The phanerous or palpable bone processes, muscles and tendons are taken as positioning marks; pressing areas where appear sour, numb, or distensible and other sensations is considered as the principle of press positioning. So acupoints position method is the combination of observation and palpation. Different insertion methods can effectively relieve the accretive bursae synovialis, tendon, joint capsule and the compressed nerve, so that shoulder bi syndrome is relieved.

Measurement report on the horizontal position relationship between the umbilicus and the 2nd lum- bar spinal process in adults / 中国针灸

The impact factors were explored to determine the horizontal positional relationship between the umbilicus and the 2nd lumbar spinal process in adults and to verify the accuracy of the localization of Shenshu (BL 23) via the umbilicus. The position of the umbilicus and the 2nd lumbar spinal process was measured in 100 participants and the data were analyzed through SPSS 20.0 software. It was found that the umbilicus and the 2nd lumbar process were not positioned horizontally. The positional relationship of these two sites was not apparently correlated with gender, age, body weight, body height, BMI, waistline and discomfort of lumbar region. The umbilicus was commonly and posteriorly projected on the site between the 4th and 5th lumbar vertebra. It is explained that the localization of Shenshu (BL23) via the umbilicus is not accurate.

Experimental Study of Needle Knife Treatment for Knee Osteoarthritis / 上海针灸杂志

Objective To explore the mechanism of therapeutic action of needle knife “regulating sinews and treating bones” on knee osteoarthritis (KOA) by observing the effect of needle knife intervention on KOA rabbit behaviors, mechanical characteristics of patellar ligament (PL), and expressions of interleukin-4 (IL-4), matrix metalloproteinase-3 (MMP-3) and aggrecan in knee cartilages.Methods Forty New Zealand rabbits were randomly allocated to blank, model, needle knife and electroacupuncture groups, 10 rabbits each. A rabbit model of KOA was made by the modified Videman method of immobilization in extension position. After model making, the needle knife and electroacupuncture groups received needle knife and electroacupuncture treatments, respectively. A behavioral assessment was made using the modified Lequesne MG knee grade evaluation method in every group after model making and treatment. The samples were taken after treatment. PL tension, stress relaxation and creep state were tested using a Bose Electro Force 3300 protracted test machine. Cartilage cell IL-4 expression was examined by ELISA. MMP-3 mRNA and aggrecan mRNA expressions were detected by real-time PCR.Results After model making, there was a statistically significant difference in the Lequesne MG score between the model and blank groups (P0.05). There was a statistically significant post-treatment difference in the Lequesne MG score between the needle knife or electroacupuncture group and the model group (P0.05).Conclusion The mechanism of action of needle knife treatment on KOA may be that it improves ligament mechanical characteristics, regulates intra-articular stress environment, and modulates aggrecan mRNA and MMP-3 mRNA expressions and inhibits cartilage degeneration through IL-4 mechanical signal pathway, to produce the therapeutic effect of “regulating sinews and treating bones”.

Study on the relationship between lower limb artherosclerosis and cardiac function in elderly patients with diabetes mellitus complicated with coronary heart disease / 中华老年医学杂志

Objective To investigate the relationship between lower limb artherosclerosis and cardiac function in elderly patients with diabetes mellitus(DM)complicated with coronary heart disease (CHD). Methods 441 cases of elderly patients were divided into four groups: the group with CHD (n=117), the group with DM(n=42), the group with DM compllicated with CHD( DM±CHD, n=132),the group without DM and CHD(NC,n=150). Systolic blood pressure (SBP), diastolic blood pressure(DBP), pulse pressure (PP), braehial-ankle pulse wave velocity (baPWV), ankle-brachial index(ABl) and toe-brachial index(TBI) were measured by the auto-survey artherosclerosis apparatus.Left ventricular posterior wall (LVPW), left atrium (LA), fractional shortening (FS), ejection fraction(EF) and EF slope were measured by the two-dimensional echocardiography. Results The baPWV was significantly higher in DM+CHD group than in DM group and NC group[(20125±354)cm/s vs (1849±467)cm/s, (1863±347) cm/s. P<0.05]. The ABI was significantly lower in DM±CHD group compared with NC, CHD and DM groups (0.91±0.23 vs 1.15±0.11,1.07±0.16 and 1.06±0.14. all P＜0.05). There were significant differences in TBI among four groups(all P<0.05) :NC group(0.905±0.15)>CHD group(0.805±0.16)>DM group(0.71±0.17)>DM+CHD group(0.625±0.17). The LA and the LVPW were significantly higher in DM+CHD group than in NC group(P<0.05). The FS and EF slopes were significantly lower in the DM+CHD group than in DM group (P<0.05) and NC group(P<0.05). The EF in DM+CHD group was significantly lower than that in other three groups (P<0.05). BaPWV showed a strong negative association with FS,EF and EF slope(r:-0.112,-0.151,-0.275. all P<0.05). ABI showed a strong positive association with FS,EF and EF slope(r:0.150,0.186,0.260. all P<0.01) ,TBI was found to have strong negative association with LA and LVPW ( r:-0.158,-0.171;all P<0.01) and have strong positive association with FS,EF and EF slope(r:0.163,0.197,0.243.all P<0.01). Conclusions The lower limb artherosclerosis is serious and cardiac function is significantly decreased in elderly patients with diabetes mellitus complicated with coronary heart disease. PWV,ABI and TBI are closely related with cardiac function and can reflect the state of cardiac function in some extent.

BACKGROUND: At present, there is no ideal way to treat auditory injury, and acupuncture would become an effective method to prevent and cure drug auditory injury.OBJECTIVE: To observe the effect of acupuncture at Yifeng, Ermen and Zhongzhu acupoints on improving histopathologic form of basilar membrane of guinea pig with drug poisoning auditory injury.DESIGN: Completely randomized design on the basis of experiment al animals.SETTING: Department of Neurology, Xuanwu Hospital, Capital University of Medical Sciences.MATERIALS: A total of 45 white male guinea pigs with normal Preyer's reflex were selected in this study. Guinea pigs were 3-4 months old, of general grade and weighted from 250 g to 300 g. All guinea pigs were randomly divided into 5 groups: normal group, model group, Yifeng group, Ermen group and Zhongzhu group with 9 in each group.METHODS: The experiment was completed at the Laboratory of College of Acupuncture and Moxibustion Affiliated to Beijing University of Traditional Chinese Medicine from April to July 2002. ① Normal group: Guinea pigs were fed with normal feed. Other four groups: Guinea pigs were injected into muscle with 80 mg/kg gentamycin for 20 days, and guinea pigs in Yifeng group, Ermen group and Zhongzhu group were acupunctured at corresponding acupoints at the same time. Before acupuncture, guinea pigs were fixed and rapidly acupunctured into subcutaneous tissue with stainless steel needle sized 0.35 mm × 25 mm. The needle was inserted about 10 mm. According to uniform reinforcing-reducing method, the needle was thrusted once every 10 minutes with each for 30 seconds and retained for 30 minutes. The course was 20 days. ② Basilar membrane of guinea pigs was established. Amount of hair cell was calculated under optic microscope (×200) to record deletion amount of hair cell and observe activity of succinic dehydrogenase; meanwhile, ultrastructure of hair cells was observed with transmission electron microscope (×5 000). Measurement data were compared with t test among groups.MAIN OUTCOME MEASURES: Activities of succinic dehydrogenase of hair cell in stretched preparation and changes of ultrastructure of hair cell in cochlea of guinea pigs.RESULTS: All 45 guinea pigs were revolved in the final analysis. ① Comparing activities of succinic dehydrogenase: Activity in normal group was great, and structures of inter and outer hair cells were normal. Activity in mode group was reduced gradually till disappeared. Outer hair cell at base was damaged severely, and there was significant difference from that in normal group (P ＜ 0.01). Activity of succinic dehydrogenase in Yifeng group was changed a little as compared with that in normal group, and difference was not obviously (P ＞ 0.05). Activity of succinic dehydrogenase in Ermen group was decreased, and hair cell showed a little swelling and deletion. Activity of succinic dehydrogenase in Zhongzhu group was decreased remarkably, and outer hair cell at base was damaged severely.There was significant difference between Ermen group and Zhongzhu group as compared with that in normal group (P ＜ 0.01). ② Deletion amount of outer hair cells in basilar membrane of guinea pigs: Amounts in Yifeng group, Ermen group and normal group were less than those in model group (P ＜ 0.05-0.01), but those in Zhongzhu group were similar to those in model group. ③ Ultrastructure: Structure of hair cell of cochlea was normal in normal group, pathological changes were observed on hair cells in model group, and pathological changes in acupuncture groups were milder than those in model group. Pathological changes of outer hair cells were mild in Yifeng group, structure of hair cells was changed a little in Ermen group,pathological changes in Zhongzhu group were severe, but its degree was milder than that in model group.CONCLUSION: Acupuncture can improve and maintain the activity of succinic dehydrogenase, relieve or resist toxic effect of gentamycin, especially at Yifeng, then at Ermen and Zhongzhu.
