Through researches of channels and collaterals and clinical practice of many years, the authors understand that Chinese medicine, which considers the human body as an interrelated, mutual constraints, whole, dynamic living system, has gradually become an important part of modern medicine. Channels and collaterals are a closed loop system which is communicated and linked by energy and information in the form of electromagnetic oscillation, reflecting many characteristics similar to quantum. Channels and collaterals are not a fixed organizational structure. Studies on channel and collaterals find that the track of the propagated sensation along channels (PSC) have the phenomenon drifting about. This exactly reflects the law of channels dynamically running. By information triggering and living resonance, channels and collaterals bring into play entirely regulative action. The innovative treatment of channels and collaterals followed by characteristics and laws of quantum can get a better curative effect. Theory of channels in the position of quantum information medical science provides an important breach for modernization of Chinese medicine.

Objective To investigate whether simple visual assessment of FVERVOT(the right ventricular outflow tract Doppler flow velocity envelop) graphs aids in hemodynamic differentiation. Method The hemodynamics, echocardiography, and clinical data of 88 patients with pulmonary hypertension (PH) were reviewed. The FVERVOTgraphs were categorized into normal pattern (no notch; NN), late systolic notch pattern (LSN) or mid-systolic notch pattern (MSN). Results The pulmonary vascular resistance (PVR) was highest in the MSN pattern (9.2±3.5 WU; P＜0. 001), in comparison with LSN (5,7 ±3. 1 WU) and NN (3.3±2.4 WU) patterns. The ratio of stroke volume to pulse pressure (compliance) also varied with different patterns of FVERVOr graph (MSN = 1.2 ± 0. 5; LSN = 1.7 ± 0.8; NN = 2.6 ± 1. 7, P = 0.001 and 0.04 respectively compared with NN). The specificity and sensitivity of MSN were 96% and 71%, respectively in case of a PVR ＞ 5 WU (PPV 98%). In the patients with PH, any notching pattern of FVERVOT graph was highly associated with PVR ＞ 3 WU (OR = 22.3, 95 % CI: 5.2 ～ 96.4), whereas the NN pattern predicted a PVR ≤3 WU and pulmonary artery wedge pressure (PAWP) ＞ 15 mmHg (OR =30.2, 95%CI: 6.3 ～ 144.9). Conclusions Visual inspection of the shape of the FVERVOT graphs provides insight into the hemodynamic status of patients with PH.

OBJECTIVETo observe the effect of acupuncture combined physical training and relearning on stroke patients.

METHODSA multi-center, randomized controlled trial design was adopted. A total of 364 stroke patients were recruited and randomly assigned to the experimental group (184 cases) and the control group (180 cases). Patients in the experimental group received acupuncture combined with physical training and relearning, while those in the control group only received physical training and relearning. All received four weeks of treatment. Effects on Fugl-Meyer motor function, neurological impairment, activities of daily living difference were compared before treatment, after treatment, 2 and 5 months after follow-ups between the two groups.

RESULTSTotally 353 patients completed this trial, 179 in the experimental group and 174 in the control group. (1) compared with before treatment, brief Fugl-Meyer motor functions scores and FIM scored obviously increased, and scores for neurological impairment obviously decreased in the two group. Besides, the increment of brief Fugl-Meyer motor functions scores and FIM scores was obviously higher in the experimental group than in the control group at month 2 and 5 of follow-ups; scores for neurological impairment was obviously lower in the experimental group than in the control group. The increment of FIM scores was obviously higher in the experimental group than in the control group at month 5 of follow-ups (P < 0.05, P < 0.01). (2) There was statistical difference in inter-group comparison of total Fugl-Meyer motor functions scores and FIM scores, or scores for neurological impairment (P < 0.01). The improvement of Fugl-Meyer motor functions grading and neurological impairment grading was obviously superior in the experimental group at month 2 and 5 of follow-ups. The distribution of FIM grading was also better in the experimental group at month 5 of follow-ups (P < 0.05, P < 0. 01).

CONCLUSIONSBoth acupuncture combined exercise training and relearning and physical training and relearning could effectively promote the rehabilitation of stroke patients, reduce their neurological impairment degrees, improve motor functions and independent capacities. Better long-term efficacy could be obtained by acupuncture combined exercise training and relearning.

Objective To evaluate the long-term effectiveness of the first set 8 methadone maintenance treatment (MMT) clinics in China. Methods Repeated cross-sectional surveys were conducted on the first month after the enrollment and 5 years later,among drug users who received MMT,using a standard questionnaire.Data on demographic characteristics,HIV-related high-risk bchaviors,criminal records associatcd with drug use and related family/social functions were collected and analyzed.Results There were 252 and 195 participants being interviewed at the baseline and the 5-year surveys,respectively,.Of them,66 participants were involved in both surveys.There was no significant differences on factors as ethnicity,level of education,working status,marital status and living status (P＞0.05) between the baselinc and the 5-year surveys.Compared with data from the baseline survey,participants' behavior on drug abuse (100.0％ vs.24.1％,P＜0.001 ),needle sharing behavior ( 19.4％ vs.0.0％,P ＜ 0.001 ),and exchanging sex for drugs ( 34.5 ％ vs.0.0％,P＜0.001 ) had significant decreases at the 5-year survey.Rates on condom use ( 10.6％ vs.25.0％,P=0.004),and having jobs (27.8％ vs.47.7％,P＜0.001 ) had been improved significantly,while self-reported criminal cases related to drug use (15.1％ vs.1.5％,P＜0.001) and the contacts with drug users (88.9％ vs.31.3％,P＜0.001) had been significantly reduced after joining the MMT program.Conclusion MMT could play an active role in reducing the HIV-related high-risk behaviors,criminal cases associated with drug abuse as well as enhancing the family and social functions of the MMT patients.Providing high quality service to the MMT clinic and trying to keep the drug users stick to the program remain difficult.It was also important to improve the training programs for staff working at the MMT clinics.

The most common manifestations of inflammatory bowel disease （IBD） are Crohn's disease and ulcerative colitis， and the global incidence of IBD is on the rise. Traditional Chinese medicine （TCM） is advantageous in the treatment of IBD. IBD， with TCM names based on clinical symptoms， mostly belongs to recurrent dysentery， long dysentery， diarrhea， dysentery， bowel， and other categories. In TCM pathogenesis of IBD， spleen deficiency and exuberant dampness predominate in the whole course of the disease. Since the lung is associated with the large intestine and the lung Qi and spleen Qi are interconnected， the lung Qi and spleen Qi are deficient and the dampness and heat accumulate internally， which caused collateral obstruction by stagnant blood and the development of IBD. From the perspective of "associating lung with large intestine"，it is believed that the main mechanism of IBD is the Qi imbalance and abnormal metabolism of fluids in the lung and the intestine，and the nutrient-Yin injury of the lung and the intestine. According to the chronic， recurrent， and diffuse pathogenesis characteristics and main clinical manifestations of IBD， IBD is closely related to the lung and the intestine. In terms of therapeutic principles， IBD can be treated by tonifying the spleen and replenishing the lung， which highlights the treatment of the intestine from the lung. To be specific， in time of tonifying the spleen and removing dampness， the intestine is regulated by tonifying the spleen and replenishing the lung. Shenling Baizhusan， a commonly used classical prescription for IBD， is mainly potent in replenishing Qi， invigorating the spleen， draining dampness， checking diarrhea， and especially "reinforcing earth to generate metal". It can enhance the function of the lung through "reinforcing earth to generate metal"， which in turn regulates the intestine and promote the improvement of IBD. The present study clarified the mechanism of Shenling Baizhusan in regulating the intestine by tonifying the spleen and replenishing the lung. On the basis of modern research， its therapeutic effect on IBD was achieved through multiple links， such as regulation of the level of inflammatory factors， immunoregulation， barrier function improvement via mucosal repair， and intestinal flora. The findings of this study are expected to provide new ideas for the regulation of the lung-spleen-large intestine axis in the syndrome differentiation and treatment of IBD and subsequent experimental research.

As part of systematic research of Corydalis hendersonii,a typical traditional Tibetan herbal medicine with clearing heat,relieving pain,and lowering blood pressure effects,a novel isoquinoline alkaloid,named hendersine G was isolated from the ethanol extract of the whole plant by various chromatographic techniques,including silica gel column,reverse phase column (ODS),Sephadex LH-20,and semi-preparative HPLC.Its structure was elucidated by MS,NMR and other spectroscopic data analysis.Hendersine G can be regarded as a condensation product of a tetrahydroberberine and a succinic acid,however,its absolute configuration has not been determined due to its structural complexity and less obtained amount.This present study provides an inspiration for further exploration of novel molecules from C.hendersonii.

OBJECTIVETo explore the operative technique and clinical results of using peroneal perforator-based sural neurofasciocutaneous flaps to repair skin and soft tissue defects in lower extremities.

METHODSFrom January 2009 to March 2012, 26 patients with skin and soft tissue defects at distal region of leg and foot were hospitalized. Among them, 9 patients suffered from tendon or bone exposure at the distal region of leg after injury due to traffic accident; 4 patients suffered from skin defects in the ankle as a result of electric injury; 8 patients suffered from chronic ulcer at the distal part of leg and foot; 5 patients suffered from plantar pressure ulcer. After debridement, soft tissue defect sizes ranged from 11 cm×5 cm to 18 cm×13 cm. According to the position and size of the defects, peroneal perforator-based sural neurofasciocutaneous flaps were designed and procured to repair the skin and soft tissue defects. The size of flaps ranged from 12 cm×6 cm to 20 cm×15 cm. Flap donor sites were closed by direct suture or skin grafting.

RESULTSTwenty-five flaps survived completely. Only one flap suffered partial margin necrosis in the size of 2 cm×1 cm, which was healed after dressing change. Patients were followed up for 6 to 12 months. The appearance and sensation of flaps were satisfactory; no ulcer occurred; the movement of lower extremities was normal.

CONCLUSIONSIt is suitable to repair the skin and soft tissue defects at distal region of leg and foot with the peroneal perforator-based sural neurofasciocutaneous flap, as it possesses reliable blood supply, long and non-bulky pedicle, and sufficient available size. The operation is also easy to perform.

OBJECTIVE: To evaluate the efficacy of sepsis risk calculator (SRC) in guiding antibiotic use in neonates with suspected early-onset sepsis (EOS). METHODS: A total of 284 neonates with a gestational age of ≥ 35 weeks were enrolled as the control group, who were hospitalized in the Children's Hospital of Chongqing Medical University from March to July, 2019 and were suspected of EOS. Their clinical data were retrospectively collected and the use of antibiotics was analyzed based on SRC. A total of 170 neonates with a gestational age of ≥ 35 weeks were enrolled as the study group, who were admitted to the hospital from July to November, 2020 and were suspected of EOS. SRC was used prospectively for risk scoring to assist the decision making of clinical antibiotic management. The two groups were compared in terms of the rate of use of antibiotics, blood culture test rate, clinical outcome, and adherence to the use of SRC. RESULTS: Compared with the control group, the study group had a significantly higher SRC score at birth and on admission ( CONCLUSIONS The use of SRC reduces the rate of empirical use of antibiotics in neonates with suspected EOS and does not increase the risk of adverse outcomes, and therefore, it holds promise for clinical application.
