BACKGROUND:Intraocular refractive operation with phakic intraocular lens implantation has been used in highly refractive errors patients with over-high diopter and thinner corneal thickness, which has the advantages of reversibility and retain the eye's accommodation. OBJECTIVE:To evaluate the safety and stability of posterior chamber phakic intraocular lens implantation in comparison with Lasik correction for high myopia. METHODS:Total y 126 col ege students with high myopia, 63 males and 63 females, aged (21.87±1.18) years, were randomly divided into test and control groups. In the test group, col ege students received posterior chamber phakic intraocular lens implantation, while those in the control group were subject to Lasik correction. During 1-year fol ow-up, naked vision, corrected visual acuity, contrast sensitivity, and postoperative untoward reaction were observed, and the effectiveness and safety indexes were calculated in the two groups. RESULTS AND CONCLUSION:The effectiveness and safety indexes in the test group were both superior to those in the control group (P<0.05). After 1 year of fol ow-up, the contrast sensitivity light and dark environment in the test group was significantly improved, which was also higher than that in the control group. Decreased night vision and glare was found in five cases of the control group and one case of the test group. These findings indicate that posterior chamber phakic intraocular lens implantation is safe and effective that can improve the visual quality in clinic.

BACKGROUND:Insulin-like growth factor-1(IGF-1), a main active factor in growth hormone (GH), plays various biological functions, such as improving cognitive ability and anti-apoptotic action.
OBJECTIVE:To detect the expressions of GH and IGF-1 in the temporal cortex of Lewis dwarf rats, and to explore the effect of different concentrations of GH on the differentiation of hippocampal nerve stem cels (NSCs).
METHODS:Lewis dwarf rats aged 11(adult) and 20 (senile) month olds and normal wild-type rats were euthanized by decapitation, underwent the craniotomy quickly, and the temporal cortex in the cold saline was extracted. GH and IGF-1 levels were detected using western blotting. After isolation, purification and identification of the rat hippocampal NSCs, the effect of GH in different concentrations (10, 30, 90μg/L) on the NSCs differentiation was determined at 96 hours after culture.
RESULTS AND CONCLUSION:The GH level in the temporal cortex did not differ significantly among rats (P > 0.05). While the IGF-I level in the temporal cortex of Lewis dwarf rats was significantly higher than that of the wild-type rats (P < 0.05). The GH level in the temporal cortex of adult female Lewis dwarf rats was significantly lower than that of the male rats (P < 0.05). Immunofluorescence showed that the proportion ofβ III-tubulin-positive neurons was significantly higher than that in the control group (P < 0.05) after the hippocampal NSCs and precursor cels cultured for 96 hours with GH (30μg/L), but there was no significant difference between the control group and treatment group with GH of 10 or 90μg/L. These results suggest that GH and IGF-I are expressed in the temporal cortex of both Lewis dwarf and wild-type rats which are independent from pituitary GH and the peripheral circulating IGF-1. Additionaly, GH can promote the differentiation of hippocampal NSCs and precursor cels into neurons.

Objective To evaluate the value of medical treatment in the management of SAP.Methods From January 2000 to December 2011,a total of 1064 cases out of 931 SAP patients were admitted and retrospectively analyzed.The etiologies,severity score,complication rates,therapies,effectiveness and costs of those SAP cases were summarized.Results There were 559 males and 372 females with a mean age of (51 ± 15)years old.The main cause was biliary tract disease (58.3％),followed by fat-rich diet (31.2％),hyperlipidemia (13.6％) and alcohol (7.1％).At the time of admission,95.5％ of SAP patients presented with level D disease according to Balthazar CT severity index,26.0％ had a Ranson score ≥3 and 30.1％ had an APACHE Ⅱ score ≥ 8.There were 42.7％ cases complicated with systemic inflammatory response syndrome (SIRS).Acute lung injury and acute respiratory distress syndrome (ARDS),acute kidney injury,shock or heart failure,acute liver dysfunction,and diffuse intravascular clotting (DIC)occurred in 24.0％,8.1％,5.4％,3.2％,and 1％ of all patients,respectively.Other complications of SAP included abdominal cavity bleeding (n =17),pseudocyst bleeding (n =9),pancreatic abscess (n =78) and gastrointestinal fistula (n =33).Totally 25 (2.3％) patients died in hospital and 36 (3.4％) patients were discharged against advice,with an overall treatment success rate of 94.3％.The mean hospital stay was (23.7 ± 19.2) d,and the average cost was 52.3 thousands of RMB.Conclusions A comprehensive treatment pathway relying on medical treatment,focusing on organ function support and assisted by miniinvasive intervention may improve the treatment success rate of SAP,which is worth of further application.

Objective:To investigate the effect of decompression of optic nerve canal for traumatic optic neuropathy (TON) via lateral supraorbital approach.Methods:A retrospective case series study was performed to analyze clinical data of 23 TON patients admitted to First People's Hospital of Huzhou from December 2013 to June 2019. There were 16 males and 7 females, aged 17-51 years [(34.3±2.2)years]. Degree of visual impairment included count fingers in 4 patients, hand motion in 4, light perception in 9 and loss of light perception in 6. Visual evoked potential examination (VEP) was performed in 15 patients before surgery. The amplitude of P100 completely disappeared in 5 patients, and the amplitude of P100 was lower than the lower limit of normal value and the latency prolonged in 10 patients. The time from injury to operation was 3 h-14 days [(3.3±0.6)days]. All patients underwent decompression of optic nerve canal via supralateral orbital approach, and dural repair was performed simultaneously in 11 patients with dural rupture. Intraoperative fractures and meningeal tears, duration of operation, blood loss, and hospitalization duration were recorded. Combined with the classical visual acuity improvement assessment method and the World Health Organization (WHO) low vision and blind grading standard, visual acuity was compared before operation, at 10 days and 3 months after operation. Glasgow Coma Scale (GCS) was used to evaluate patients' state of consciousness in the course of the disease. Glasgow Outcome Scale (GOS) was used to evaluate the prognosis. Incidence of complications was observed as well.Results:All patients were followed up for 12-16 weeks [(13.5±2.4)weeks]. Intraoperative microscopic exploration revealed that all patients had optic nerve canal fracture, 3 patients had frontal fracture with dural rupture, and 8 patients had ethmoid bone fragment with anterior skull base dural rupture. The duration of operation was 108.5-224.3 minutes [(151.8±30.2)minutes], including (32.5±8.4)minutes for craniotomy. The intraoperative blood loss was 90.5-165.3 ml [(121.3±15.5)ml]. The hospitalization was 14-26 days [(19.7±3.4)days]. The visual acuity of 13 patients (57%) improved and 5 patients (39%) relieved from blindness 10 days after operation, showing significant difference compared with the preoperation ( P<0.05). The visual acuity of 17 patients (74%) improved and 9 patients (39%) relieved from blindness at 3 months after operation. There was significant difference in visual acuity examined between 10 days and 3 months after operation ( P<0.05). Six patients were invalid, and 4 of them had no light perception before operation and the amplitude of VEP examination completely disappeared. All patients had GCS of 15 when left the hospital and GOS of 5 at 3 months after operation. One patient had cerebrospinal fluid rhinorrhea and healed after 7 days of supine position. No secondary hematoma, epilepsy or intracranial infection occurred during follow-up. Conclusion:Optic canal decompression via the lateral supraorbital approach can improve visual acuity in early stage and increase the rate of out of blindness, with low postoperative complications and satisfactory functional recovery, which is worthy of clinical application.

Objective:To compare the efficacy and safety between WangShiBaoChiWan and mosapride in the treatment of functional dyspepsia (FD).Methods:From September 2019 to September 2020, patients with postprandial fullness and early satiation who met the Rome Ⅳ criteria for FD diagnosis were enrolled from 15 hospitals, including the First Affiliated Hospital of Naval Medical University (Shanghai Changhai Hospital), Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical College. The subjects were randomly divided into WangShiBaoChiWan (experimental) group and mosapride (control) group in the ratio of 1∶1. The treatment regimens were WangShiBaoChiWan+ mosapride simulator, WangShiBaoChiWan simulator+ mosapride, respectively with a treatment period of 2 weeks. The primary efficacy outcome was the improvement rates of main symptoms before and after treatment, the secondary efficacy primary efficacy outcome was the total clinical effective rate and the change of the single symptom score. And the safety indicator included adverse events. Independent sample t-test, paired t-test and chi-square test were used for statistical analysis. Results:A total of 251 FD patients were enrolled in the full analysis set, including 124 in the experimental group and 127 in the control group; 241 FD patients were in the per-protocol analysis set, including 117 in the experimental group and 124 in the control group. The analysis of per-protocol analysis set showed that the improvement rates of the main symptoms of the experimental group and the control group were (66±29)% and (60±30)%, respectively, and the difference was not statistically significant ( P>0.05). The improvement rate of the main symptoms of the experimental group reached 117% of that of the control group, which exceeded the expected non-inferiority standard of 80%. The total clinical effective rates of the experimental group and the control group were 76.07% (89/117) and 75.81% (94/124), respectively, and the difference was not statistically significant ( P>0.05). The results of full analysis set showed that the incidence of adverse events of the experimental group and the control group was 1.62% (2/124) and 1.57% (2/127), respectively, and the difference was not statistically significant ( P>0.05). There were no serious adverse events in the two groups. Conclusion:The improvement rate of the main symptoms of WangShiBaoChiWan is not inferior to that of mosapride in the treatment of FD, and it has good safety.

Objective To explore the role of continuous pulse output (PICCO) monitoring in treatment of patients with traumatic acute diffuse brain swelling (PADBS). Methods Eighty-six PADBS patients, admitted to our hospital from January 2014 to October 2017, were routinely given brain invasive intracranial pressure (ICP) monitoring after admission. At the same time, the patients were given bone flap decompression and hematoma clearance according to the condition of the diseases. After surgery, according to the wishes of family members, patients were divided into two groups (n=43):patients from treatment group accepted PICCO monitoring on the basis of ICP monitoring, and the treatment plan was adjusted according to the monitoring results; and the treatment plan in patients from control group was adjusted according to traditional central venous pressure (CVP) monitoring results on basis of ICP monitoring. Results One week after operation, the ICP in the treatment group was (14.36±2.82) mmHg when the cerebral perfusion pressure (CPP) was controlled between 50 and 70 mmHg, which was significantly different from the ICP in the control group (18.58±2.25) mmHg (P<0.05). Two weeks after treatment, Glasgow Coma Scale (GCS) scores of the treatment group (10.87±1.72) were significantly higher than those of the control group (8.18±1.16, P<0.05). The incidences of posttraumatic cerebral infarction (PTCI) and neurogenic pulmonary edema (NPE) in the treatment group (11.6％, 18.6％) were significantly lower than those of the control group (25.6％, 34.9％, P<0.05); the recovery rate (76.7％) in the treatment group was significantly higher than that in the control group (60.5％, P<0.05); the mortality rate (9.3％) was significantly lower than that in the control group (18.6％, P<0.05). Conclusion On the basis of intraventricular ICP monitoring, combined PICCO monitoring can effectively control ICP, improve cerebral perfusion, reduce the incidence of PTCI and NPE, improve the prognosis, and reduce the mortality in PADBS patients.
