Objective To analyze the clinical features and the surgical treatment outcomes of patients with tuberculous otitis media and mastoiditis. Methods The medical records of 16 patients (18 ears) with tuberculous otitis media and mastoiditis, who received surgery in Beijing Tongren hospital,were reviewed. Results The common symptoms were otorrhea and hearing loss, and 3 patients demonstrated severe sensorineural hearing loss. Three patients demonstrated a peripheral-type facial palsy.Temporal bone high resolution CT scans demonstrated the entire tympanum and mastoid air cells were occupied by soft tissue. Eleven patients demonstrated bone destruction and sequestra was found in 7 temporal bones. Contemporary pulmonary tuberculosis were diagnosed in 7 of the 16 patients. Surgical removal of disease lesions in combination with anti-tuberculosis treatment were given to 15 patients. Other than 2 cases of tuberculous otitis media and mastoiditis diagnosed by pre-operational biopsy through the perforated tympanic membrane, the remaining 14 cases were diagnosed intra-oporatively or post-operatively. No relapse of tuberculosis in the middle ear and mastoid were found after follow-up for more than 1 year, except for the one case that was lost to follow-up. The 3 cases of facial nerve palsy almost recovered to normal.Conclusions Clinicians should suspect tuberculous otitis media and mastoiditis if clinical findings include refractory otorrhea, total occupation of the tympanic cavity and mastoid ari cells by soft tissue, and erosion of the bone or sequestra as shown by CT. A history of tuberculosis should be asked carefully in order to differentiate tuberculous otitis media and mastoiditis. The patients who received surgery and anti-tuberculosis chemotherapy achieved more rapid healing of the ear.

BACKGROUNDThe hybrid procedure for coronary heart disease combines minimally invasive coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) and is an alternative to revascularization treatment. We sought to assess the predictive value of four risk-stratification models for risk assessment of major adverse cardiac and cerebrovascular events (MACCE) in patients with multivessel disease undergoing hybrid coronary revascularization.

METHODSThe data of 120 patients were retrospectively collected and the SYNTAX score, EuroSCORE, SinoSCORE and the Global Risk Classification (GRC) calculated for each patient. The outcomes of interest were 2.7-year incidences of MACCE, including death, myocardial infarction, stroke, and any-vessel revascularization.

RESULTSDuring a mean of 2.7-year follow-up, actuarial survival was 99.17%, and no myocardial infarctions occurred. The discriminatory power (area under curve (AUC)) of the SYNTAX score, EuroSCORE, SinoSCORE and GRC for 2.7-year MACCE was 0.60 (95% confidence interval 0.42 - 0.77), 0.65 (0.47 - 0.82), 0.57 (0.39 - 0.75) and 0.65 (0.46 - 0.83), respectively. The calibration characteristics of the SYNTAX score, EuroSCORE, SinoSCORE and GRC were 3.92 (P = 0.86), 5.39 (P = 0.37), 13.81 (P = 0.32) and 0.02 (P = 0.89), respectively.

CONCLUSIONSIn patients with multivessel disease undergoing a hybrid procedure, the SYNTAX score, EuroSCORE, SinoSCORE and GRC were inaccurate in predicting MACCE. Modifying risk-stratification models to improve the predictive value for a hybrid procedure is needed.

OBJECTIVEWe investigate the magnitudes of waveform changes of arterial blood gas (ABG) in patients with heart failure.

METHODSFive patients with heart failure were selected, continuous collecting radial artery blood and measured PaO2, PaCO2, pHa and Sao2. We selected two typical breaths cycles of waveform changes of ABG from each patient for data analysis. Comparison of the adjacent highest and lowest values to verify the presence of a periodic waveform changes of ABG, and in addition, we used t test to analysis the range of waveform changes of ABG in patients with heart failure and patients with normal cardiac function and compared whether the difference between them.

RESULTSThe 5 patients (2 surgical and 3 ICU) with heart failure, were 4 male and 1 female, (69 ± 7)year, (169 ± 10) cm, (75 ± 19)kg, LVEF = (38 ± 3)%. The heart beat numbers for full blood into the blood sampling pipe were 17 ± 2, and all covered more than 2 breath cycles. There were significant changes of PaO2, PaCO2, [H+]a and SaO2 (P < 0.05). The magnitudes of changing PaO2, PaCO2, [H+]a and Sao2 were (7.94 ± 2.02)mmHg, (1.18 ± 0.56)mmHg, (0.54 ± 0.17)nmol/L and (0.21 ± 0.07)%, and they were (6.1 ± 1.5)%, (3.2 ± 1.5)%, (1.5 ± 0.5)% and (0.2 ± 0.1)% from their mean respectively. Even these magnitudes fo all ABG parameters were trendily lower than those of patients with normal cardiac function, but only PaO2 and [H+]a were significant (P < 0.05).

CONCLUSIONUsing this simple continuous beat-by-beat arterial blood sampling method, we obtained a clear evidence of periodic waveform of ABG parameters following by breath cycle in patients with heart failure, but the magnitude trendily be decreased.

Protoberberine alkaloids belong to the quaternary ammonium isoquinoline alkaloids, and are the main active ingredients in traditional Chinese herbal medicines, like Coptis chinensis. They have been widely used to treat such diseases as gastroenteritis, intestinal infections, and conjunctivitis. Studies have shown that structural modification of the protoberberine alkaloids could produce derivative compounds with new pharmacological effects and biological activities, but the transformation mechanism is not clear yet. This article mainly summarizes the researches on the biotransformation and structure modification of protoberberine alkaloids mainly based on berberine, so as to provide background basis and new ideas for studies relating to the mechanism of protoberberine alkaloids and the pharmacological activity and application of new compounds.

In colorectal cancer surgery, loop ileostomy is sometimes necessary to prevent anastomotic leakage. Although ileostomy reversal is relatively simple, postoperative complication is inevitable. In recent years, laparoscopic surgery has been gradually applied in ileostomy reversal due to its small trauma, fast recovery, and low complications, exhibiting satisfactory short-term outcomes. This review analyzes the application of the laparoscopic technique in ileostomy surgery and explores the potential of total laparoscopic surgery, aiming to provide a new perspective for the clinical application of laparoscopic ileostomy reversal.

Objective:To examine the safety and feasibility of using fusion indocyanine green fluorescence imaging (FIGFI) technique for intraoperative evaluation of colorectal perfusion in the totally laparoscopic left colectomy.Methods:A retrospective cohort study was conducted to collect the clinical data of 58 patients with left colon cancer who underwent totally laparoscopic surgery at the Colorectal Surgery Department, Cancer Hospital, Chinese Academy of Medical Sciences from October 2016 to December 2019. There were 39 males and 19 females, aging (57.0±10.1)years(range:28 to 75 years). According to whether the FIGFI was used during the operation, they were divided into 36 cases in the study group and 22 cases in the control group. The clinical pathological characteristics, operative and postoperative recovery of the two groups were compared by t test, χ 2 test, and Fisher exact test. Results:All the 58 patients underwent R0 resection with totally laparoscopic surgery. In the study group, due to poor bowel blood flow after cutting the mesentery (Sherwinter score = 1), 1 patient had to be expanded the resection range until the blood flow was rich(Sherwinter score≥3), and 1 patient in the control group had the complication of postoperative anastomotic leakage of grade A. Compared with the control group, the operation time in the study group was shorter ((156.3±43.5) minutes vs. (180.4±41.3) minutes, t=-2.083, P=0.042). However, there were no significant differences in the amount of blood loss, postoperative hospital stay, postoperative time of anal exhaust, length of bowel resection, number of lymph nodes dissected, and in the incidence of postoperative complications between the two groups. Median follow-up period was 23 months (range: 18 to 37 months). There were no long-term postoperative complications such as ischemic enteritis and anastomotic stenosis in both groups. Conclusions:The FIGFI is safe and feasible to assess the blood supply of intestinal segment and anastomosis during totally laparoscopic left hemicolectomy, and is easy to operate. It is expected to reduce the incidence of anastomotic leakage.
