Objective To observe the effects of electroacupuncture on genu recurvatum after stroke. Methods 80 stroke patients with genu recurvatum were randomly assigned to treatment group (n=40) and control group (n=40). The control group accepted routine rehabilitation, and the treatment group accepted electroacupuncture at Yanglingquan (GB34), Futu (ST32), Weizhong (BL40), Chengshan (BL57) and Zusanli (ST36) in addition, for 30 days. The incidence of effectiveness was compared between groups. All the patients were assessed with range of motion (ROM) of knee and Fugl-Meyer Assessment of lower limbs (FMA) before and after treatment. Results The incidence of effectiveness was 72.5% in the treatment group, which was more than 55% in the control group (P<0.05). The ROM and score of FMA improved more in the treatment group than in the control group (P<0.05). Conclusion The electroacupuncture can promote the recovery of genu recurvatum after stroke.

To observe the clinical effect of Yisui decoction plus western medicine in treating multiple system atrophy patients, totally 65 patients from China-Japan Friendship hospital during 2008-2012 with complete clinical data and received consecutive traditional Chinese medicine and western medicine treatment for more than 3 months were observed changes of traditional Chinese medicine symptom score, part 1 of unified multiple system atrophy rating scale, orthostatic hypotension before treatment and after 3 months treatment. After 3 months treatment, total effective rate of traditional Chinese medicine symptom was 70.8%. Compared with before treatment, score of part 1 of unified multiple system atrophy rating scale was obviously reduced after 3 month treatment (P < 0.001). Ex- cept swallow function without significant improvement, the remaining projects of unified multiple system atrophy rating scale were im- proved obviously (P < 0.05), of which the most obvious differences were orthostatic symptoms, falls and intestinal function (P < 0.001). Orthostatic hypotension after 1 month treatment and 3 month treatment was obviously better than before treatment (P < 0.001). There was no significant difference in orthostatic hypotension between 1 month treatment and 3 month treatment. The research results show that Yisui decoction plus western medicine has a certain effect on improving clinical symptoms of multiple system atrophy patients, especially has a significant effect on orthostatic hypotension, and can maintain a stable clinical effect in a certain period of time.

OBJECTIVETo investigate the biocompatibility of new bone tissue engineering scaffolds, A:D, L-polylactic acid (PDLLA)/polylactic acid-polyethylene glycol-polylactic acid-polylactic acid (PLA-PEG-PLA)/Tricalcium phosphate and B: PDLLA/PLA-PEG-PLA in vivo, compared with PDLLA in repair of a rabbit mandibular body defect.

METHODS24 New Zealand adult rabbits were divided into 4 groups randomly. 15 mm x 6 mm defects were made surgically in the bilateral mandibular bodies and each hemi-mandible was assigned as an experimental unit. The defects were randomly repaired with scaffold materials in each group. Specimens obtained were evaluated with general observation, X-ray, histomorphology and computerized graphical analysis at 2, 4 , 8, 12 weeks after surgery.

RESULTSCompared with PDLLA, the new scaffold materials B showed biocompatibility. At the same time the quantity of new bone produced was much more than that in control group (P<0.05). The new scaffold materials A showed the clear chronic granulomatous inflammation.

CONCLUSIONNew scaffold material B had sound biocompatibility. It was much better than PDLLA. So it may be an ideal bone tissue engineering scaffold material. A is not adapted to be used as scaffold material.

Objective:To construct a cognitive training program suitable for elderly patients with mild cognitive impairment based on horticultural therapy, so as to effectively slow down the cognitive decline of patients with mild cognitive impairment.Methods:Through searching the Chinese and English database literature of cognitive intervention from July 2000 to July 2020 and field visits to nursing homes, the draft intervention plan was formed. Two rounds of focus group interview were held to consult experts in cognitive impairment and geriatric care, etc., and to revise the intervention plan.Results:In the two rounds of focus group interview, the expert positive coefficient was 100%, the expert judgment basis was 0.84, the expert familiarity degree was 0.84, and the expert authority coefficient was 0.84. In the end, a 10-week cognitive intervention program targeting six cognitive domains -- "visuospatial/executive ability", "memory ability", "language ability", "attention ability", "abstract ability" and "naming ability" was formed, and the implementation steps of the program were improved.Conclusions:The construction process of cognitive training program for patients with mild cognitive impairment based on horticultural therapy theory is rigorous, scientific and feasible, and can be used to guide the cognitive training of patients with mild cognitive impairment.

OBJECTIVETo investigate the efficacy of continuous propofol infusion via the common carotid artery for general anesthesia.

METHODSForty adult patients scheduled for abdominal surgery were randomly assigned into 2 groups to receive propopol via the common carotid artery (IC group, n=20) or via the median cubital vein (IV group, n=20). Anesthesia was induced with intravenous administration of drugs and maintained with continuous propofol infusion via the common carotid artery or the median cubital vein, with the CSI stabilized at 40-/+5 till the end of the operation. During the anesthesia, intravenous injection of fentanyl (3 microg.kg(-1).h(-1)) and vecuronium (50 microg.kg(-1).h(-1)) were given intermittently to maintain the analgesia and muscular relaxation. The dose of propofol used, hemodynamics and recovery of the patients were observed.

RESULTSThe dose of propofol used during the surgery to maintain a CSI of 40-/+5 was significantly lower in group IC and than in group IV (2.57-/+0.67 vs 5.72-/+1.37 mg.kg(-1).h(-1), P<0.01). In group IC, the blood pressure was elevated in more than half of the patients and in some cases, the elevation exceeded one third of baseline value and needed intervention with hypotensive drugs. In the IV group, the patients' blood pressure remained stable and varied within the amplitude of 15% of the baseline level. Recovery of spontaneous breathing and consciousness was more quickly in group IC than in group IV (P<0.05).

CONCLUSIONLoss of consciousness and nervous reflex can be achieved with propofol infusion via the common carotid artery, which reduces propofol dose by about 50% in comparison with intravenous infusion and allows more rapid recovery of spontaneous breath and consciousness.

OBJECTIVETo compare the effects of common carotid artery and femoral vein administration of propofol for electrocerebral silence (ES) on circulatory and respiratory function and the dosage of propofol required during ES in dogs.

METHODSEight dogs were anesthetized by common carotid arterial and femoral vein administration of propofol for ES for 1 h. The time of consciousness loss and recovery, dose of propofol during ES, mean arterial pressure, heart rate, respiration rate, end-tidal carbon dioxide, SpO2, cerebral state index (CSI) and anal temperature were continuously monitored. Changes in the outcome variables were analyzed at 7 time points, namely the baseline, upon loss of consciousness, at 10 s, 30 min and 1 h of CSI=0, and recovery of CSI and consciousness.

RESULTSCarotid artery propofol administration produced ES with only half of the dose for intravenous administration. Compared with the baseline values, the mean artery pressure and respiration rate remained unchanged or decreased transiently during ES with carotid artery propofol administration. In contrast, intravenous propofol administration resulted in systemic hypotension and severe respiratory depression.

CONCLUSIONCarotid artery propofol administration produces ES with a much smaller dose than intravenous propofol administration without causing systemic hypotension or respiratory depression.

Objective To evaluate the efficacy and safety of Willis covered stent in the treatment of traumatic carotid cavernous fistulae (tCCF).Methods The imaging and clinical data of 7 patients with tCCF treated with Willis covered stent in Shanghai Punan Hospital from November 2015 to June 2018 were analyzed retrospectively.Results Seven Willis covered stent were used in 7 patients.Immediately after stent release,angiography showed that the fistulae completely disappeared in 6 cases.One patient had a small amount of endoleak,and there was still a small amount of endoleaks after balloon dilatation.It was not further treated.There were no operative complications.During 3-12 months follow-up,no new neurological deficits were found in all patients.Angiographic follow-up of 2 patients showed that the fistulae completely disappeared without recurrence.The internal carotid arteries were patent,no in-stent stenosis and stent displacement.Conclusions Wills covered stent can be used as a treatment for tCCF.Its efficacy is satisfactory and the safety is good.

OBJECTIVE: Plant-derived cytotoxic transgene expression, such as trichosanthin (tcs), regulated by recombinant adeno-associated virus (rAAV) vector is a promising cancer gene therapy. However, the cytotoxic transgene can hamper the vector production in the rAAV producer cell line, human embryonic kidney (HEK293) cells. Here, we explored microRNA-122 (miR122) and its target sequence to limit the expression of the cytotoxic gene in the rAAV producer cells. METHODS: A miR122 target (122T) sequence was incorporated into the 3' untranslated region of the tcs cDNA sequence. The firefly luciferase (fluc) transgene was used as an appropriate control. Cell line HEK293-mir122 was generated by the lentiviral vector-mediated genome integration of the mir122 gene in parental HEK293 cells. The effects of miR122 overexpression on cell growth, transgene expression, and rAAV production were determined. RESULTS: The presence of 122T sequence significantly reduced transgene expression in the miR122-enriched Huh7 cell line (in vitro), fresh human hepatocytes (ex vivo), and mouse liver (in vivo). Also, the normal liver physiology was unaffected by delivery of 122T sequence by rAAV vectors. Compared with the parental cells, the miR122-overexpressing HEK293-mir122 cell line showed similar cell growth rate and expression of transgene without 122T, as well as the ability to produce liver-targeting rAAV vectors. Fascinatingly, the yield of rAAV vectors carrying the tcs-122T gene was increased by 77.7-fold in HEK293-mir122 cells. Moreover, the tcs-122T-containing rAAV vectors significantly reduced the proliferation of hepatocellular carcinoma cells without affecting the normal liver cells. CONCLUSION HEK293-mir122 cells along with the 122T sequence provide a potential tool to attenuate the cytotoxic transgene expression, such as tcs, during rAAV vector production.
