To observe the clinical efficacy of spleen, liver and kidney-strengthening formula combined with polyethylene glycol interferon in the treatment of HBeAg positive chronic hepatitis B(HP-HBV).One hundred and twenty-six patients with HP-HBV, who were treated in the hospital from June 2012 to December 2014, were selected and injected with polyethylene glycol interferon α-2a(or α-2b). The treatment course for the patients lasted for 24 weeks. Base on the level of HBV-DNA, patients are divided into response group and poor response group. According to random number table, the poor response group were randomized into control group and test group. Patients in the control group were injected with polyethylene glycol interferon α-2a(or α-2b), and patients in the test group were treated with spleen, liver and kidney-strengthening formula combined with polyethylene glycol interferon. Clinical efficacies of the 2 groups were observed, and changes in the level of HBeAg, ALT and HBV-DNA were observed before treatment and at the 24th week after treatment, and virological and serological response, biochemical responses, integral clinical symptoms and signs, adverse reactions were observed after 48 weeks of treatment.After 24 weeks of treatment, the response group was significantly better than the poor response group in HBeAg, ALT and the level of HBV-DNA(P<0.05). After 48 weeks of treatment, there was statistical significance in HBV-DNA negative conversion rate, HBeAg negative conversion rate between the 2 groups(P<0.05), and the test group was better in the two indicators. And the test group was significantly lower than the control group in clinical symptoms and signs score at the 48th week after treatment(P<0.05), with a significantly lower adverse reaction rate than the control group(P<0.05).Combination of spleen, liver and kidney-strengthening formula and polyethylene glycol interferon α-2a was effective and safe in the treatment of chronic hepatitis B, and so worth promoting in clinic.

ObjectiveTo explore the effect of virtual reality on upper limb function in stroke patients through diffusion tensor imaging (DTI). MethodsFrom September, 2021 to March, 2023, 80 stroke patients in the Fuzhou Second General Hospital were randomly divided into control group (n = 40) and experimental group (n = 40). Both groups received routine rehabilitation, while the experimental group received virtual reality training additionally, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and Action Research Arm Test (ARAT) before treatment, after treatment and after four-week follow-up; and they were scaned with DTI to measure the fractional anisotropy (FA) and relative anisotropy (RA) of cerebral peduncle and posterior limb of inner capsule of the affected side before and after treatment. ResultsTwo cases dropped in each group. The FMA-UE and ARAT scores increased in both groups after treatment and follow-up (F > 2.790, P < 0.001), and increased more in the experimental group than in the control group (t > 2.297, P < 0.05). FA and RA in the posterior limb of inner capsule increased in both groups after treatment (t > 21.013, P < 0.001), and increased more in the experimental group (t > 2.006, P < 0.05). The d-value of FA of the posterior limb of internal capsule before and after treatment (ΔFA) was positively correlated with the d-value of FMA-UE score (r > 0.362, P < 0.05) in both groups, the ΔFA of the posterior limb of internal capsule was positively correlated with the d-value of ARAT score (r = 0.459, P < 0.01). ConclusionVirtual reality training can promote the recovery of upper limb function in stroke patients, which may associate with the conductivity of posterior limb of inner capsule.

Nuclear receptors are transcriptional regulators involved in almost all biological processes such as cell growth, differentiation, apoptosis, substance metabolism and tumor formation, and they can be regulated by small molecules that bind to them. Autophagy is a special way of programmed cell death and it is a highly conserved metabolic process. Once autophagy defects or excessive autophagy occur, the disease will develop. In recent years, numerous studies have shown that nuclear receptors are related to autophagy. Therefore, this paper mainly reviews the research progress on nuclear receptors involved in the regulation of autophagy, and focuses on the mechanism of several nuclear receptors involved in the regulation of autophagy, aiming at understanding the molecular basis of how nuclear receptors participate in regulating autophagy, as well as providing possible ideas and strategies for the treatment of corresponding diseases.

Directed evolution is a cyclic process that alternates between constructing different genes and screening functional gene variants. It has been widely used in optimization and analysis of DNA sequence, gene function and protein structure. It includes random gene libraries construction, gene expression in suitable hosts and mutant libraries screening. The key to construct gene library is the storage capacity and mutation diversity, to screen is high sensitivity and high throughput. This review discusses the latest advances in directed evolution. These new technologies greatly accelerate and simplify the traditional directional evolution process and promote the development of directed evolution.

OBJECTIVETo explore the effect of nano carbon tattooing on the lesion localization in the early colon cancer for additional surgical procedure after endoscopic resection.

METHODSThirty-five patients with early colon cancer accepted additional surgical procedures after endoscopic resection in Fuzhou General Hospital of PLA from May 2014 to November 2016. All the patients underwent nano carbon tattooing before the end of endoscopic resection: 0.1 ml carbon nanoparticles suspension was respectively injected into the normal intestinal submucosa from 1 cm outside the 4 sites (upper, lower, left and right) of the lesion border by colonoscopy, marking the original lesion location and guiding the subsequent additional surgery. Data of these 35 cases were summarized.

RESULTSAll the 35 cases, including 22 males and 13 females, with a mean age of 46.5 years(range 35-70), completed the endoscopic disposable carbon nano marking, and the mean operative time was 7.5 minutes(range 5-10). No bleeding, no perforation and no adverse reaction occurred. Four to 21(10±3.5) days after endoscopic resection, the patients received the additional surgery as a result of pathological specimens of endoscopic resection in 10 cases of vascular invasion, 7 cases of severe submucosal infiltration, 7 cases of more than grade G2 in tumor budding, 6 cases of poorly differentiated adenocarcinoma and undifferentiated carcinoma, and 5 cases of positive margin. All the patients underwent laparoscopic surgery. The mean time of intraoperative detection and lesion location was 3.0 minutes(range 1-5). All tattooings were clearly visible under the naked eye. The colon wedge resection were performed in 5 cases, colon segment resection in 14 cases, and radical resection of colon cancer in 16 cases. The operative time was 45 to 180(120±30) min, and the blood loss was 50 ~ 200(50±15) ml. There was no intraoperative complications. The first gas passage time was 12 to 48(24±8) h. The postoperative hospital stay was 10 to 3(6.5±2.5) d. There was no postoperative complication and no perioperative mortality.

CONCLUSIONNano carbon tattooing is helpful for the accurate location of primary lesions in the additional surgical operation after endoscopic resection of early colon cancer, and it can improve the safety and precision of surgical procedures, especially for laparoscopic surgery.

OBJECTIVE: To compare the effect of two different arthroscopic procedures, threading lasso fixation and full-thickness conversion, for repairing articular-sided partial-thickness supraspinatus tendon tear. METHODS: From July 2015 to November 2018, 21 patients with articular-sided partial-thickness supraspinatus tendon tears underwent arthroscopic modified threading lasso fixation repair(group A). There were 12 males and 9 females in the group, with an average age of(53.2±6.4)years old. Twenty-four patients with articular-sided partial-thickness supraspinatus tendon tears received arthroscopic full-thickness conversion repair(group B). In this group, there were 14 males and 10 females, with an average age of (55.7±5.2) years old. The American Shoulder and Elbow Surgeons (ASES) score and University of California Los Angeles (UCLA) shoulder score were used to evaluate preoperative and postoperative clinical function. MRI was used to examine the healing status of the reconstructed rotator cuff. RESULTS: All patients were followed up, and the duration ranged from 20 to 27 months, with a mean of (23.7±3.1) months. In threading lasso fixation group, ASES score and UCLA score increased from 50.6±6.4 and 15.6±2.7 preoperatively to 87.3±5.2 and 31.6±2.4 postoperatively. In full-thickness conversion group, ASES score and UCLA score increased from 52.3±5.6 and 16.8±2.4 scores to 90.1±4.8 and 32.1±2.8. There were also no significant differences in ASES score and Constant score between the two groups before and after operation. There were no significant differences in rotator cuff healing between the two groups(χ²=2.374, P=0.128). CONCLUSION For the treatment of articular-sided partial-thickness supraspinatus tendon tears both arthroscopic repairs employing threading lasso fixation and full-thickness conversion could achieve satisfactory clinical results, and there are no significant differences in clinical outcomes between the two techniques. Arthroscopic repair with threading lasso fixation is a novel transtendinous procedure in which integrity of the tendon can be preserved.

Ischemic stroke is a major health crisis causing high mortality and morbidity. The key treatment relies on the rapid intervention to dissolve thrombus, to reduce bleeding side effect and re-canalize clotted blood vessels using clot lysis drugs. Tissue plasminogen activator (tPA) is the only FDA-approved drug for ischemic stroke, but it has many limitations in clinical use. In recent years, the development of thrombolytic drugs and treatment strategies based on tPA has been progressed rapidly. Here we review the recent progress in this field, including the contributions from us and others, to promote the future development of novel thrombolytic drugs.

Drug eluting stents (DESs) have revolutionized the interventional cardiology over the past decade since the first DES became commercially available in Europe in 2002. Compared to bare metal stents that are deployed to keep the vessel open by mechanical force, DESs have an additional function of reducing restenosis by the action of the drug on the target site. Coatings on the stent surface which ensure the maximum delivery of therapeutic agents to the target site with minimal systematic toxicity, also play an important role in adjusting the drug release profile. Coating material and technology not only affect the surface biocompatibility and the integrity maintenance during the implanting process, but also decide the way of drug delivering and transmitting from the coating. This paper reviews the basic principles of DES coating design, the categories of DES coatings, the commonly used clinical DES coatings and their efficiency in reducing restenosis, and finally provides the future perspectives for DES coatings.
