Objective To evaluate the possible roles of IL-4,IL-18 in hepatitis B virus (HBV) infection.Methods Serum IL-4,IL-18 level was measured using ELISA,and serum HBV-DNA content was detected by FQ-PCR.Results There was significant in serum IL-4,IL-18 level between the fulminant hepatitis patients and chronic hepatitis patients or normal controls (P

Objective To investigate the mechanism of an inhibitor of NADPH oxidases,diphenylene iodonium (DPI),in preventing radiation-induced lung injury.Methods Totally 48 adult SD male rats were randomly classified into 4 groups:control group (C),radiation group (R),radiation plus DPI group (R + D) and DPI group (D).The radiation induced pulmonary injury model was preformed by using 6 MV X-rays to deliver 8 Gy per day for 5 consecutive days with 40 Gy in total to the thorax of each animal.Rats in R + D group were subcutaneously administered with 0.02％ DPI (1 mg/kg) at 1 h prior to radiation while rats in D group received the same dose of DPI without radiation.DPI was given from 3 d before radiation to 30 d after the first radiation.Rats in C and D groups received the same dose of saline.Animals were sacrificed at 1 month and 6 months after radiation,respectively.The lungs were removed and processed for HE and Masson staining,hydroxyproline content measurement,and TGF-β1 immunohistochemical detection.Results At 1 month post-radiation,rats in R group showed typical alveolitis,the level of hydroxyproline was (0.69 ± 0.05) μg/mg,and the positive area of TGF-β1 expression was (39.97 ± 0.90) ％,while the level of hydroxyproline in R + D group was (0.55 ± 0.03) μg/mg and the positive area of TGF-β1 expression was(33.83 ± 1.55) ％,rats in R + D group showed less severe alveolitis compared with R group(t =5.32,5.93,P ＜0.05).At 6 months post-radiation,rats in R group showed typical lung fibrosis with hydroxyproline level of (1.04 ±-0.02) μg/mg and TGF-β1 expression of (37.80 ± 0.85) ％,whereas the hydroxyproline level in R + D group was (0.85 ± 0.02) μg/ mg,the TGF-β1 expression was(23.93 ± 1.16)％,rats in R + D group showed moderate lung fibrosis(t =15.77,16.68,P ＜ 0.05),rats in C and D group had no noticeable changes.Conclusions Diphenylene iodonium could prevent radiation-induced lung injury by reducing the level of hydroxyproline and the expression of TGF-β1.

Objective To summarize the experience of the ventriculoperitoneal shunt (VPS) in communicating hydrocephalus and its complications. Methods The clinical features, operative techniques and outcome of 100 patients with hydrocephalus were analysed retrospectively. Results Ninety-five (95%) cases had a good result. Postoperative complications were found in 6(6%) cases including shunt apparatus blockage (4 cases) and shunt infection (2 cases). All the cases improved after taking the corresponding measures. Conclusion VPS is the most common shunt style for communicating hydrocephalus. The shunt apparatus blockage and infection are common postoperative complications. Intraoperative aseptic technique, the minimally invasive procedure, and the optimal placement of shunt tube may play an important role in improving the outcome of cerebrospinal fluid shunting surgery for communicating hydrocephalus.

OBJECTIVETo analyze the effect difference of wave, intensity, time and treatment frequency by orthogonal design so as to explore the optimal parameters of scalp electroacupuncture (EA) for rehabilitation effect on children of cerebral palsy.

METHODSNinety children of cerebral palsy were assigned into 9 groups by orthogonal design, 10 cases in each one. The acupoints were bilateral excitable area, foot motor sensory area, speech two area, speech three area, balance area, and intelligent nine acupoints, including Shenting (GV 24), Sishencong (EX-HN 1), and bilateral Benshen (GB 13) and Touwei (ST 8). EA was applied at bilateral excitable area and speech three area. We designed an orthogonal experiment with four factors and three levels. We studied wave (sparse wave of 2 Hz, density wave of 100 Hz, sparse and density wave of 2 Hz /100 Hz), intensity (1 mA, 2 mA, intensity based on tolerance), time (10 min, 20 min, 30 min), frequency (once a day, once every other day, twice a week). The Gesell developmental scale was used to evaluate the developmental quotient (DQ); and gross motor function measure (GMFM), motor function before and after treatment.

RESULTSThe optimal parameters for DQ and GMFM were 2 Hz/100 Hz, 20 min, once every other day. .

CONCLUSIONThe optimal parameters for cerebral palsy may be 2 Hz/100 Hz, 20 min, once every other day.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.
