BACKGROUND: Management of gastric leak after sleeve gastrectomy (SG) is challenging due to its unpredictable outcomes. We aimed to summarize the characteristics of SG leaks and analyze interventions and corresponding outcomes in a real-world setting. METHODS: To retrospectively review of 15,721 SG procedures from 2010 to 2020 based on a national registry. A cumulative sum analysis was used to identify a fitting curve of gastric leak rate. The Kaplan-Meier method and log-rank tests were performed to calculate and compare the probabilities of relevant outcomes. The logistic regression analysis was conducted to determine the predictors of acute leaks. RESULTS: A total of 78 cases of SG leaks were collected with an incidence of 0.5% (78/15,721) from this registry (6 patients who had the primary SG in non-participating centers). After accumulating 260 cases in a bariatric surgery center, the leak rate decreased to a stably low value of under 1.17%. The significant differences presented in sex, waist circumference, and the proportion of hypoproteinemia and type 2 diabetes at baseline between patients with SG leak and the whole registry population ( P = 0.005, = 0.026, <0.001, and = 0.001, respectively). Moreover, 83.1% (59/71) of the leakage was near the esophagogastric junction region. Leakage healed in 64 (88.9%, 64/72) patients. The median healing time of acute and non-acute leaks was 5.93 months and 8.12 months, respectively. Acute leak (38/72, 52.8%) was the predominant type with a cumulative reoperation rate >50%, whereas the cumulative healing probability in the patients who required surgical treatment was significantly lower than those requring non-surgical treatment ( P = 0.013). Precise dissection in the His angle area was independently associated with a lower acute leak rate, whereas preservation ≥2 cm distance from the His angle area was an independent risk factor. CONCLUSIONS Male sex, elevated waist circumference, hypoproteinaemia, and type 2 diabetes are risk factors of gastric leaks after SG. Optimizing surgical techniques, including precise dissection of His angle area and preservation of smaller gastric fundus, should be suggested to prevent acute leaks.

Objective: To explore the correlation between the attachment type of lateral pterygoid muscle (LPM) and the position of temporomandibular joint (TMJ) disc in patients with temporomandibular disorders (TMD) by using wireless amplified magnetic resonance imaging detector (WAND) coupled with conventional head and neck joint coil for high resolution imaging of TMJ. Methods: Eighty-five patients with TMD diagnosed by oral and maxillofacial surgeons of Guizhou Provincial People's Hospital from October 2019 to January 2022 were collected. A total of 160 TMJ were included. There were 16 males and 69 females, aged (32.7±14.2) years. All patients were scanned with open, closed oblique sagittal and coronal WAND coupled head and neck coils with bilateral TMJ. Based on TMJ and LPM high resolution imaging, to explore the correlation between LPM attachment types and the position of TMJ disc in TMD patients, and to evaluate the potential clinical value of LPM attachment types in TMD patients. χ² test and Pearson correlation analysis were used to evaluate the correlation between LPM attachment type and TMJ disc location. Results: There were three types of LPM attachment: type Ⅰ in 51 cases [31.9% (51/160)], type Ⅱ in 77 cases [48.1% (77/160)] and type Ⅲ in 32 cases [20.0% (32/160)]. There was a significant correlation between the type of LPM attachment and the position of articular disc (χ²=28.20, P=0.002, r=0.776). There was no statistical significance between the type of LPM attachment and the reversible displacement of articular disc (χ²=0.24, P=0.887, r=0.825). Conclusions: There is a correlation between the attachment type of LPM and the position of the disc in TMD patients. WNAD coupled with conventional head and neck joint coil TMJ high resolution scan can provide reliable imaging evidence for TMD patients in evaluating the type of LPM attachment and the location of disc.

OBJECTIVE: To test the effect of Banxia Xiexin Decoction (, BXD) on the contraction and relaxation of gastric smooth muscle (SM) in diabetic gastroparesis (DGP) model rats, and to explore the mechanism of BXD in the prevention and treatment of DGP through experiments of signal pathway both in vivo and in vitro. METHODS: Sixty Sprague-Dawley rats were divided into 6 groups according to a random number table: control group, model group, high-, medium- and low-dose BXD groups (9.2, 4.6 and 1.8 g/(kg·d), respectively), and domperidone group (10 mg/(kg·d)), 10 rats per group. DGP model was established initially by a single intraperitoneal injection of streptozotocin (STZ), and was confirmed by recording gastric emptying, intestinal transport velocity and gastric myoelectric activity of rats after 2 months. Each group was treated with a corresponding drug for 4 weeks. The mRNA and protein expressions of phospholipase C (PLC), inositol triphosphate (IP RESULTS: Compared with the model group, high- and medium-dose BXD and domperidone significantly increased the expressions of PLC, IP CONCLUSIONS Treatment with high- and medium-dose BXD significantly attenuated STZ-induced experimental DGP in rats. The therapeutic effect of BXD on DGP rats might be associated with the PLC-IP

OBJECTIVE: To discuss the clinical efficacy and safety of balloon-expandable stent in the treatment of symptomatic atherosclerotic cerebral artery stenosis in the middle cerebral artery(MCA), and to assess the appropriate methods of postoperative follow-up auxiliary examination. METHODS: A total of 67 patients with symptomatic atherosclerotic cerebral artery stenosis in the MCA were treated with balloon-expandable stent. The clinical data and follow-up data were collected and then analyzed retrospectively.RESULTS: the success rate of the surgical treatment with balloon-expandable stent was 98.51%(66/67). The incidence of symptomatic perioperative complications was 4.48%(3/67). All patients received clinical follow-up, and the auxiliary examination methods of the internal condition lesion of the stent included transcranial Doppler(TCD) or digital subtraction angiography(DSA). The incidence of in-stent restenosis or occlusion was 8.96%(6/67), and the consistency rate of stent restenosis or occlusion between TCD and DSA was75.00%, and the incidence of symptomatic in-stent restenosis or occlusion was 2.99%(2/67). It was found that there were two patients with recurrent stroke in cerebrovascular stent related region but without in-stent restenosis, and within 1 year of follow-up, the incidence of symptomatic stroke in stent-associated areas after operation was 10.44%(7/67). CONCLUSION: The treatment with balloonexpandable stent for symptomatic MCA stenosis has good clinical effect. The incidence of perioperative complications is low and the incidence of stroke in stent-associated areas after operation is low. TCD is an effective way of follow-up after the arterial stenting in the brain, which can play a role in the early detection of the in-stent restenosis, and its consistency with DSA is high.

OBJECTIVETo detect the influence of compatibility of rhubarb with different traditional Chinese medicines (TCM) on extracted quantities of AQs, and to provide scientific basis for the clinical code for rhubarb preparation.

METHODThe influence of compatibility of rhubarb with different traditional Chinese medicines (saponin, alkaloids, flavonoids TCMs, animal medicines and mineral medicines) on decocting volume of anthraquinone substance was detected using ultra performance liquid chromatography.

RESULTIn comparable conditions, more AQs were extracted from mixed decoction of rhubarb and saponin medicinal materials (Astragali Radix, Notoginseng Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, Polygalae Radix, Ginseng Radix et Rhizoma) than single decocting of rhubarb. The mixed decoction of rhubarb and alkaloid medicinal materials (Coptidis Rhizoma, Sophorae Flavescentis Radix, Prepared Aconiti Lateralis Radix Praeparata, Phellodendri Chinensis Cortex, Aconiti Lateralis Radix) caused a remarkable decrease in extracted quantities of AQs. And the mixed decoction of rhubarb and mineral medicines (Natrii Sulfas, Gypsum Fibrosum, Ostreae Concha, Alumen) also resulted in less extracted quantities of AQs to varying degrees. Besides, more rhubarb AQs were extracted from mixed decoction with Curcuma than single decoction. But less rhubarb AQs were observed in mixed decoction with Lonicerae Flos, Rehmanniae, Artemisiae Herb and Forsythiae Fructus than single decoction to varying degrees. In the study, the maximum extracted quantities of AQs is 2. 3-fold higher than the minimum, the largest difference existed in the extracted quantity of physcion which was 13.5 times.

CONCLUSIONIn compatibility between rhubarb and different TMCs, mixed decoction and single decoction show different influences on extracted quantity of rhubarb AQs. It is proved that more AQs may be extracted from mixed decoction between rhubarb and saponin medicinal materials, whereas less AQs may be observed in mixed decoction between rhubarb and alkaloid medicinal materials.

OBJECTIVEThis study was to compare the performance of three HIV antibody confirmatory assay kits in confirming early HIV infection.

METHODSFive HIV antibody-positive plasma specimens were ten-fold serially diluted and then detected by ELISA. The above diluted specimens were detected with the following three HIV antibody confirmatory assay kits to analyze their sensitivity, including Wantai-RIBA (Recombinant immunoblot assay, Beijing Wantai Biological Pharmacy, China), MP-WB (HIV Blot 2.2 WB, MP Biomedicals Asia Pacific Pte. Ltd., Singapore) and INNO-LIA (INNO-LIA(TM) HIV I/II Score, Innogenetics N.V., Belgium), respectively. These kits were further used to detect 48 ELISA-reactive specimens from 11 sets of HIV seroconversion specimens (a total of 48 samples) which were previously detected as HIV antibody-positive by ELISA.

RESULTSWhen 5 samples were diluted to 100 fold, Wantai-RIBA still can detect them positive. Among the 48 HIV antibody-positive specimens detected with ELISA, the confirmation positive rate for Wantai-RIBA, MP-WB and INNO-LIA were 97.92% (47/48), 81.25% (39/48) and 91.67% (44/48), respectively. There was statistically significant difference between the confirmatory results of Wantai-RIBA and MP-WB (χ(2) = 6.13, P < 0.05), as well as between those of INNO-LIA and MP-WB (χ(2) = 5.48, P < 0.05); however, there was no statistically significant difference between those of Wantai-RIBA and INNO-LIA (χ(2) = 1.33, P > 0.05). For other six HIV seroconversion panels containing indeterminate specimens, the average seroconversion period of time for Wantai-RIBA, MP-WB and INNO-LIA were 0.7, 13.3 and 3.7 days, respectively.

CONCLUSIONCompared with MP-WB, Wantai-RIBA and INNO-LIA could reduce the window period to confirm early HIV infection.
