Objective:To explore the effect of electroacupuncture on the expression of N-methyl-D-aspartic acid (NMDA) in the spine and the activity of α 2 adrenergic receptors in rats with stress urinary incontinence (SUI). Methods:In all, 48 adult female rats were randomly divided into a sham operation group, a model group and an acupuncture group. The sham operation group received sham vaginal distention. Both the model and acupuncture groups had SUI induced using endovaginal balloon dilatation. The former group then had no further intervention, while the latter was given acupuncture on the sanyinjiao point for one week. Urodynamic testing and leak point pressure (LPP) determination were then conducted with all three groups, as well as urethral sphincter electromyography. The expression of NMDA in the L 6-S 1 spinal segments using the polymerase chain reaction and α 2 adrenergic receptor activity was analyzed using western blotting. Results:No significant differences in the urodynamic variables were observed among the three groups. However, compared with the sham operation group, a significant decrease in the average LPP and the frequency and amplitude of the external urethral sphincter electromyography was observed in the model group. Moreover, compared with the model group, the acupuncture group showed significantly increased average LPP and higher electromyographic frequency and amplitude. The average mRNA and protein expression of NMDA in the spine were also significantly higher in the acupuncture group, as was the average α 2 receptor activity. Conclusions:Vaginal distention is an effective method of establishing urinary incontinence in rats. Electroacupuncture can not only improve the ability to store urine, it also increases urination, which may be related to the up-regulation of the expression of NMDA and α 2 adrenergic receptors.

Objective: To explore the effect of low-dose Maren Soft Capsule (MSC) on constipation and colonic mucosa. Methods: Patients (208 cases) with colon slow transit constipation and mixed constipation were divided into treatment and control groups. MSC (two pills, once daily) and Sennae Folium (5 g) were given to the patients in the treatment and control groups, respectively, for 10 months. The recovery rate, total significant efficiency, and total efficiency were determined by defecation frequency and gastrointestinal transmission experiment. The side effects such as bloating and abdominal pain were observed. Results: The recovery rate in the treatment group was lower than that in the control group, and the total significant efficiency and total efficiency were similar to those in the control group. There was no colon melanosis in the treatment group after 10 month, while 26.9% of the patients in the control group were observed with colon melanosis. Conclusion: The low-dose MSC has the therapeutic effect on constipation with high safety.

This paper summarized the experience of Professor FANG Dingya in staged treatment of Sjögren's syndrome from the perspective of dryness toxin. It is believed that the cause of Sjögren's syndrome is externally-contracted dryness， consumption of essence and fluid， congenital and acquired essence deficiency， depleted essence and insufficient blood， and the core mechanism is internal accumulation of dryness toxin. The treatment can be divided into three stages， that is dryness toxin transforming into fire-heat， damp-heat and phlegm-stasis， from the perspective of dryness metal qi transformation. It is emphasized to dispel pathogen mainly， to clear and moisten with yin-nourishing medicinals in supplementation， and to treat by stages based on syndrome differentiation. For dryness toxin with fire-heat， it is suggested to moisten dryness， resolve toxins and subdue fire， with self-made Runzao Jiedu Decoction （润燥解毒汤） in modification. For dryness toxin with damp-heat， the method of nourishing yin， clearing heat and draining dampness should be used， and Chunze Decoction （春泽汤） in modification is suggested. For dryness toxin with phlegm-stasis， it is recommended to unblock collaterals， disperse phlegm and dissipate stasis， with self-made Sanyu Xiaotan Decoction （散瘀消痰汤） in modification.

Coronavirus disease-2019 (COVID-19) is highly contagious. In the early stages of the disease, the symptoms of coldness, dampness and depression in the lungs often appear, including fever, fatigue, soreness, dry cough, poor appetite, and white greasy tongue coating. During the development of the disease, the damp toxin epidemic often enters the inner and generates heat, and the damp heat epidemic toxin blocks pleurodiaphragmatic sites, the triple energizer and lungs, with manifestations of chest tightness, shortness of breath, exacerbation after exercise, or high fever without bringing down, poor appetite, bitterness in mouth, fatigue, diarrhea, loose stools, and yellow and thick tongue fur. As the pathogen can go outward or enter more deeply inside to cause death at the moment, it is the crucial time to treat the disease. In this study, Haoqin Qingdantang was used to clear dampness and heat, reconcile Shaoyang channel and recover the triple energizer, detoxify the dampness fever epidemic toxin, and block the toxin inside, with a good efficacy. This prescription focuses on smoothing the Shaoyang gallbladder channel and the triple energizer, and regards the spleen and stomach as the acquired essence. In the prescription, Erchentang reconciles the spleen and stomach, elevates clear Qi and lower turbid Qi. Bupleuri Radix is added to increase its detoxification function, and Paeoniae Rubra Radix is added to circulate the blood and prevent pathogen from the blood. When the condition improves, Sweet Wormwood Herb and talc are often withdrawn, and Codonopsis is added to nourish the spleen and stomach, to strengthening vital qi to eliminate pathogenic factor. Based on the cases of COVID-19 treated in Wuhan Jinyintan Hospital, this paper summarized some experience of applying Haoqin Qingdantang.

Perimenopausal syndrome refers to a series of physical and mental symptoms, caused by the fluctuation of the sex hormones in the menopause, which is one of the common diseases in gynecology. The incidence of sleep disorders in perimenopausal women is increasing significantly. Both Chinese medicine and Western medicine are trying to exploring its pathologic mechanism to find the safe and effective methods of treatment. Menopausal sleeping disorder is the same as the perimenopause syndrome and insomnia category in traditional Chinese medicine. Kidney deficiency is the basic characteristic of perimenopause, whether kidney essence, kidney Qi, kidney Yin or kidney Yang can lead to blood stasis. It is believed that this disease results from kidney deficiency in the root and blood stasis in the tip, and on this basis women affected by many factors will result in disharmony between heart and kidney. In clinical practice, The method of tonifying kidney and activating blood applied to treat perimenopause syndrome with insomnia was testified to be effective. Therefore the author thought that kidney deficiency and blood stasis and disharmony between heart and kidney were the key factors of patients with insomnia in perimenopause.

Hepatic osteodystrophy （HO） should be treated by stages based on the differentiation of root deficiency and branch excess. The root cause of HO is the insufficiency of the liver， spleen， and kidney， and the branch onset should be differentiated by stages that in the incubation， the pathogenesis is shaoyang （少阳） constraint and block and cardinal disturbance， while in the attack period， it is turbid toxin， static heat， scorching marrow and withering bones. In treatment， attention should be paid to regulating and tonifying the depletion of the liver， spleen， and kidney to cultivate the foundation. In the incubation period， it is suggested to put focus on unblocking cardinal disturbance of shaoyang liver and gallbladder so as to regulate and harmonize qi and blood. In the attack period， the focus should be on dissolving stasis， removing turbidity， and clearing the source to promote gallbladder function and bone strength. In clinical practice， medication should be modified according to individual symptoms， and the root and the branch， the primary and the secondary should be differentiated to closely follow the pathogenesis and be tailored according to the symptoms. At the same time， reasonable and safe medication should be emphasized to protect liver function.

Based on Chaihu Biejia Decoction （柴胡鳖甲汤， CBD） created by Professor LIU Duzhou， a newly modified CBD has been formulated. The differentiation and treatment of liver cirrhosis can be divided into three stages， that is， the early stage when liver cirrhosis is about to be， the middle stage when liver cirrhosis is formulated after long accumulations， and the late stage when liver cirrhosis has been transformed. Following the pathogenesis， it is recommended to differentiate the abnormal exuberance of zang-fu （脏腑） organs， qi or blood， deficiency or excess， cold or heat in three stages， and newly modified CBD is taken as the basic formula for further modifications. In early stage of liver cirrhosis， the treatment is mainly to invigorate blood and dissolve stasis， clear dampness and heat， and modifications should be made in accordance with the different causes flexibly. The treatment for the middle stage is to soften hardness and dissipate masses， dissolve stasis and clear heat， while fortifying the spleen and supplementing kidneys is accompanied. In the later stage when the healthy qi declines， and the disease is severe and evil prevails， the treatment is to reinforce healthy qi and supplement deficiency， take mild purgation and dispersion， and medicinals to promote urination， stanch bleeding， direct the turbid downward， or open the orifices can be added in accordance with the syndromes so as to treat the branch.

OBJECTIVETo analyze and summarize the clinical features and experience in surgical treatment of deep sternal infection (DSWI).

METHODSThis was a retrospective study. From January 2008 to December 2013, 189 patients with secondary DSWI after cardiac surgery underwent the pectoralis major muscle flap transposition in our department. There were 116 male and 73 female patients. The mean age was (54 ± 21) years, the body mass index was (26. 1 ± 1. 3) kg/m2. The incidence of postoperation DSWI were after isolated coronary artery bypass grafting (CABG) in 93 patients, after other heart surgery plus CABG in 13 patients, after valve surgery in 47 patients, after thoracic aortic surgery in 16 patients, after congenital heart disease in 18 patients, and after cardiac injury in 2 patients. Clean patients' wound and extract secretions, clear the infection thoroughly by surgery and select antibiotics based on susceptibility results, and then repair the wound with appropriate muscle flap, place drain tube with negative pressure. Of all the 189 patients, 184 used isolate pectoralis, 1 used isolate rectus, and 4 used pectoralis plus rectus.

RESULTSThe operative wounds of 179 patients were primary healing (94. 7%). Hospital discharge was postponed by 1 week for 7 patients, due to subcutaneous wound infection. Subcutaneous wound infection occurred again in 8 patients 1 week after hospital discharge, and their wounds healed after wound dressing. Nine patients (4. 7%) did not recover, due to residue of the sequestrum and costal chondritis, whom were later cured by undergoing a second treatment of debridement and pectoralis major muscle flap transposition. Eight patients died, in which 2 died of respiratory failure, 2 died of bacterial endocarditis with septicemia, 2 died of renal failure, 1 died of intraoperative bleeding leading to brain death and the 1 died of heart failure. The mortality rate was 4. 2% . The average length of postoperative hospital stay was (14 ± 5) days. The longest postoperative follow-up period was 40 months, the median time was 26 months, the follow-up rate was 83. 9% . Totally 179 patients were no-reinfected, 2 patients were reinfected because of artificial vascular rejection.

CONCLUSIONTo perform surgical debridement and then reconstruct the sternal defect with pectoralis major muscle flap actively for the patient is an effective measure to improve patient's survival rate.

Objective To evaluate the contrast-enhanced ultrasonography (CEUS) in quantitative diagnosis of chronic renal insufficiency. Methods Correlation of CEUS indexes with glomerular filtration rate (GFR) detected by 99mTc-DTPA renography was examined. Thirty-three cases of clinical chronic renal insufficiency were enrolled in the study. They were 15 males and 18 females with average age of (43.33±6.78) years. After intravenous bolus injection of 1 ml SonoVue,CEUS of renal cortex blood perfusion was performed successfully, and a time-intensity curve (TIC)was created with PHILIPS iU22 system's QLAB software. A 148 to 222 MBq dose of 99mTc-DTPA was injected as a bolus from antecubital vein. Renal scintigraphic images were collected immediately and GFR was obtained. Results The significant correlation coefficients between GFR and CEUS quantitative indexes were as follows: rAUC (area under curve)=0.886 (P＜0.05), rA (slope rate of ascending curve, A) =0.804(P＜0.05). However, rDPI (derived peak intensity, DPI)=0.021 (P＞0.05), rTTP (time to peak, TTP) =0.043 (P＞0.05), rα (slope rate of descending curve,α)=0.039 (P＞0.05). Conclusion CEUS can precisely display the hemodynamic change of chronic renal insufficiency, which is well correlated with GFR by 99mTc-DTPA renography.

0.05). Conclusions CEUS can accurately display the perfusion changes of CIRD model of dogs,it's more sensitive than the BUN and SCr. DPI and TTP are the most sensitive quantitative indexes of CEUS.
