OBJECTIVETo discuss the best surgical approach to the skull base neoplasms.
METHODSRetrospective analysis the 79 skull base neoplasms cases treated with surgical resection in Qilu hospital of Shandong university from 1992 to 2002. Eleven surgical approaches including midfacial degloving, frontal coronal discission, nasal eversion, maxillary swing, partial maxillary resection, total resection of orbit, mandibular swing, combination of front, temple, preauricular, post aureum, neck, and transoral approaches were used to resect the tumor which involved fossae pterygopalatine, paranasal sinuses, nasopharynx, antero, meso and posterobasilar region, lobi frontalis and lobi temporalis of cerebrum.
RESULTSSeventy-nine skull base neoplasms were totally removed and no one died from the operation. Although 5 cases complicated with cerebrospinal fluid leak and all recovered within 1 week, no serious cranium-cerebrum complication occurred. In 29 patients with benign tumor including 11 cases of meningioma, 3 cases of chondroma, 1 case of hemangio-meningioma, 1 case of cavernous hemangioma, 2 cases of osteodysplasia fibromas, 9 cases of neurofibroma, 1 case of glomus jugular tumor, 1 case of neurilemmoma, 19 have survived over 5 years and the longest one has survived over 8 years. For 50 patients with malignant tumor including 3 cases of well-differentiated squamous cell carcinoma, 17 cases of moderately differentiated squamous cell carcinoma, 11 cases of poorly differentiated squamous cell carcinoma, 1 case of undifferentiated carcinoma, 2 cases of chondrosarcoma, 5 cases of canceration of papilloma, 2 cases of adenocarcinoma, 1 case of esthesioneuroblastoma, 2 cases of malignant fibrohistiocytoma, 1 case of fibrosarcoma, 2 cases of malignant mixed tumour, 3 cases of sarcoma survival rates of 3 and 5 years were 59.2% (29/49), 38.5% (10/26) respectively.
CONCLUSIONIn order to resect the tumor completely and reduce the complication and malformation as far as possible, different surgical approaches must be designed according to the pathological changes characters and involved area,and the surgeon should select the shortest approach, avoid to damage the important neurovascular structure, and resect the tumor through the natural anatomy space by the shelter incision.

Although neuropsychiatric manifestations are common in survivors of coronavirus disease 2019 (COVID-19), the pathophysiology is not yet elucidated. Here we describe the case of a geriatric inpatient who developed post-COVID depression with psychomotor retardation, anxiety, hopelessness, executive function problems, and suicidal ideations. The language problems and cognitive impairments coemerged with the motor problems. We propose a mechanism associated with problems in energy prediction and regulation in which the coronavirus infection, which causes neuroinflammation and viral activity in the nervous system, interferes with the reward pathway and sensory prediction process. Sigma-1 receptor agonists such as sertraline may regulate energy expenditure and, thus, be beneficial to the process. The treatment improvements in our patient included those in the autonomic nervous system, activity, and circadian rhythm.

BACKGROUND: Few studies investigated serum uric acid levels in patients with acute ST-elevation myocardial infarction (STEMI). The study was to assess the clinical value of serum uric acid levels in patients with acute ST-elevation myocardial infarction (STEMI). METHODS: Totally 502 consecutive patients with STEMI were retrospectively studied from January 2005 to December 2010. The level of serum lipid, echocardiographic data and in-hospital major adverse cardiovascular events (MACE) in patients with hyperuricemia (n=119) were compared with those in patients without hyperuricemia (n=383). The relationship between the level of serum uric acid and the degree of diseased coronary artery was analyzed. All data were analyzed with SPSS version 17.0 software for Student's t test, the Chi-square test and Pearson's correlation coefficient analysis. RESULTS: Serum uric acid level was positively correlated with serum triglyceride level. Hyperlipidemia was more common in hyperuricemia patients than in non-hyperuricemia patients (43.7% vs. 33.7%, P=0.047), and serum triglyceride level was significantly higher in hyperuricemia patients (2.11±1.24 vs. 1.78±1.38, P=0.014). But no significant association was observed between serum uric acid level and one or more diseased vessels (P>0.05). Left ventricular end-diastolic diameter (LVEDd) was larger in hyperuricemia patients than in non-hyperuricemia patients (53.52±6.19 vs. 52.18±4.89, P=0.041). The higher rate of left systolic dysfunction and diastolic dysfunction was discovered in hyperuricemia patients (36.4% vs. 15.1%, P<0.001; 68.2% vs. 55.8%, P=0.023). Also, hyperuricemia patients were more likely to have in-hospital MACE (P<0.05). CONCLUSIONS: Serum uric acid level is positively correlated with serum triglyceride level, but not with the severity of coronary artery disease. Hyperuricemia patients with STEMI tend to have a higher rate of left systolic dysfunction and diastolic dysfunction and more likely to have more in-hospital MACE.
4.Advance in Mirror Therapy for Motor Rehabilitation of Stroke Patients with Hemiplegia (review)
Chinese Journal of Rehabilitation Theory and Practice 2018;24(6):659-666
Mirror therapy (MT), was first used for phantom limb pain, and afterwards used widely for stroke and peripheral nerve injury, etc. The mechanism of MT is obscure and various, mainly included mirror neuron system, visual feedback, facili-tation of motor pathways, and so on. A large quantity of researches claimed that training of unaffected limb activated ip-silateral cortex, changed conduction of pyramid tracts, and promote motor function recovery of affected limb, which cor-rected motor deficits and improved function of patients with hemiplegia (eg. finger movement and wrist flexion-exten-tion function).

Objective:To evaluate the efficacy and impacts of air tamponadein treating rhegmatogenous retinal detachments (RRD) including inferior breaks after 25G pars plana vitrectomy (PPV).Methods:A prospective non-randomized study. From November 2016 to December 2018, 110 RRD patients receiving PPV in the Ophthalmology Department of Affiliated Hospital of Nantong University were included in the study. All the patients choose the operation mode voluntarily after fully understand the condition and operation mode. There were 90 eyes in the air filling group and 20 eyes in the silicone oil filling group. There was no difference of age ( t=-0.082), sex ratio ( χ2=1.538), left or right eye ( χ2=0.839), average course of disease ( Z=-0.276), intraocular pressure ( t=3.669), axial length ( t=0.765), grade of proliferative vitreous retinopathy ( Z=-2.101), high myopia ( χ2=0.013), lens state ( χ2=1.275), logMAR BCVA ( t=-0.681), the scope of retinal detachment ( t=0.970), the site ( χ2=0.108) and numbers ( t=0.158) of the retinal holes, whether involving macula ( χ2=1.791) between the two groups ( P>0.05). At 1, 3, and 6 months after surgery, the first retinal reduction rate, BCVA increase rate, visual recovery rate, intraocular pressure, fovea retinal thickness (CFT), ellipsoid and cross sectional area, and the occurrence of postoperative complications in the two groups were observed and compared. Independent sample t test and Chi-squared test, Mann-Whitney U test, and ANOVA were used for data comparision. Results:After the first operation, retinal reattachmnents were achieved in 87 eyes (96.6%) in the air group and 19 eyes (95.0%) in the silicone oil group ( χ2=0.130, P>0.05). In the air group and the silicone oil group, there were 7 and 2 eyes with subretinal holes, whose retinal reattachmnents were achieved. At 6 months after surgery, logMAR BCVA of the eyes in the air group and the silicone oil group were 0.23±0.23 and 0.37±0.23, respectively. All of them were higher than that before operation ( t=-2.410, P<0.001). BCVA in the air group was superior to that in the silicone oil group ( P<0.05). The increase rate of BCVA of the eyes in the air group and the silicone oil group were 0.69±0.28 and 0.48±0.30 logMAR units, respectively ( t=-3.225, P<0.05). The CFT of the eyes in the air group and the silicone oil group were 226.87±42.30 μm and 234.83±36.10 μm, respectively ( t=-0.448, P=0.657). In the air group and silicone oil group, posterior cataract was observed in 15 and 4 eyes, subretinal residual fluid in 1 and 2 eyes, and visual object deformation in 3 eyes respectively. In the air group and silicone oil group, posterior cataract was observed in 15 and 4 eyes, subretinal residual fluid in 1 and 2 eyes, and visual object deformation in 3 eyes respectively. Conclusions:Air filling combined with PPV can effectively treat RRD, which is suitable for both superior and inferior holes. The visual acuity recovered well and the complication is less. The time of retinal detachment (especially the time of macular detachment) is an important factor affecting the prognosis.

OBJECTIVE:
To investigate the protective effect of losartan against on injury induced by ox-LDL in endothelial cells and the relationship with asymmetric dimethylarginine (ADMA).
METHODS:
Endothelial injury was induced by incubation with ox-LDL 100 mg/L in cultured HUVECs for 24 h, and the levels of ADMA, lactate dehydrogenase (LDH), nitric oxide (NO) and tumor necrosis factor-alpha (TNF-alpha) in the conditioned medium were measured. The activity of dimethylarginine dimethylaminohydrolase (DDAH) of cultured endothelial cells was also determined.
RESULTS:
Incubation of endothelial cells with ox-LDL 100 mg/L for 24 h induced a marked elevation of the levels of ADMA, LDH and TNF-alpha in the conditioned medium and a significant decrease in the activity of DDAH and the content of NO (P < 0.05). Pretreatment with losartan (10(-8) - 10(-6) mmol/L) significantly inhibited the increased levels of ADMA, LDH and TNF-alpha, attenuated the decreased levels of NO and the decreased activity of DDAH induced by ox-LDL (P < 0.05).
CONCLUSION
Losartan may preserve ox-LDL-induced endothelial cell injury by increasing the DDAH activity and decreasing the ADMA level.

OBJECTIVE:
To determine the effect of integrin-linked kinase(ILK) in renal tubular epithelial cells and its relation to tubular epithelial-myofibroblast transdifferentiation.
METHODS:
Wistar rats were randomly divided into 3 groups, Group normal control (n=10), Group diabetic without therapy(n=10) and Group diabetic with Losartan 20mg/(kg . d)(n=10). Five rats were killed in each group at the 8th and 16th week. The left kidneys were kept for HE and Masson staining to observe the pathological variations in the renal interstitium. ILK, alpha-SMA and Vimentin in renal tubular epithelial cells were detected by immunohistochemistry analysis.
RESULTS:
Compared with the control group, ILK, alpha-SMA and Vimentin in renal tubular epithelial cells in Group diabetes gradually increased in immunohistochemistry (P<0.01); ILK was consistent with the pathological variation of renal interstitium and was positively correlated to alpha-SMA(rs=0.621, P<0.05). In comparison with the Group diabetes, the expression of ILK, alpha-SMA and Vimentin in renal tubular epithelial cells was apparently declined (P<0.01) in Group diabetes with Losartan.
CONCLUSION
Tubular epithelial myofibroblast transdifferentiation and the over-expression of ILK, between which there may be significant connections, are important events in the progression of diabetic nephropathy. Losartan, a blocker of angiotension II type I receptor, which may down-regulate the expression of ILK in diabetic renal tubular epithelial cells, can restrain the procession of epithelial-myofibroblast transdifferentiation.

The aim of this study was to investigate the efficacy and safety of bortezomib-combined with dexamethasone, methylprednisolone and other drugs in the treatment of patients with multiple myeloma (MM). 60 MM patients including 19 de novo patients, out of them 14 patients received the treatment using regimen of bortezomib in combination with thalidomide (BT), 5 patients received bortezomib-methylprednisolone regimen (BMP). Out of 41 patients with refractory or relapsed myeloma 26 cases of MM received the treatment using regimen of bortezomib combined with methylpreamsolone (BMP), 6 cases received the treatment using regimen of bortezomib combined with cyclophosphamide, prednisone and thalidomide (BCPT), 5 cases received the treatment using regimen of bortezomib combined with cis-diaminodichloroplatimm, etoposide, cydophosphomide and dexamethasone (BDECD), 4 cases received the treatment using regimen of bortezomib combined with dexamethasone (BD). Each patient received treatment of 2-8 courses at least. Response was assessed according to the criteria of the Bladè. Adverse events were graded according to the common Toxicity Criteria, version 3.0 (NCI CTCAE, USA). The median follow-up from the start of bortezomib treatment was 9 months. The results showed that out of 19 newly diagnosed patients, 6 cares achieved CR, 6 cases achieved nearly CR, 5 cases achieved PR, 1 case achieved MR, resulting in an ORR of 94.7%. Out of 41 refractory or relapsed patients, 5 cases achieved CR, 10 cases got nearly CR, 14 cases were PR and 5 cases were MR, resulting in an ORR of 82.92%. The main toxicities were fatigue, gastrointestinal disorders, peripheral neuropathy, thrombocytopenia, herpes zoster, skin rash. All adverse events were diminished by using routine ways. In conclusion, bortezomib combined with or the drugs is a very effective regimen, its side effects are predictable and manageable.

OBJECTIVETo probe into immunological mechanisms and clinical therapeutic effect of acupoint-injection of BCG polysaccharide nuclear acid (BCG-PSN) for treatment of condyloma acuminatum (CA).
METHODSTwo hundred cases were randomly divided into 4 groups. After removed the CA by laser, the treatment group (group A) was treated with acupoint-injection of BCG-PSN, the control group I (group B) with intramuscular injection of BCG-PSN, the control group II (group C) with intramuscular injection of interferon, and the blank control group (group D) with no treatment. The levels of cellular immune function were detected before treatment and after treatment of 6 months, and the cases of relapse were recorded.
RESULTSThe cured rate of 94.3% in the group A was significantly higher than 78.0% in the group B, 80.4% in the group C and 78.2% in the group D, with significant differences (P < 0.05); in the group A, CD4+ percent increased, CD8+ percent decreased, CD4+ /CD+ ratio increased, and NK cell activity increased with a low relapse rate, and with significant differences as compared with the control groups (P < 0.05, P < 0.01).
CONCLUSIONAcupoint-injection of BCG-PSN has a better therapeutic effect and it can obviously reduce the recurrence rate of CA. The cellular immunoregulatory action is one of the mechanisms of this therapy in preventing relapse of CA.
