Objective To investigate the correlation between opportunistic infections in patients with HIV /AIDS in Dali of Yunnan Province and CD +4 lymphocyte count,discover the incidence trend of opportunistic infections in patients with HIV /AIDS in Dali and instruct early diagnosis and treatment.Methods Choosing 454 cases of opportunistic infections in patients with HIV /AIDS in Infectious Disease Dali Prefectural Hospital were chosen,ana-lyze various opportunistic infections,examining CD +4 lymphocyte count and analyze the differences of opportunistic infections on CD +4 lymphocyte count.Results 454 cases opportunistic infections with HIV /AIDS,48.24% were HCV infections,38.72% of various tuberculosis consumption phthisis,28.41% of bacterial pneumonia and 25.77%of oral condida monilia infections,high rate of opportunistic infections when CD +4 lymphocyte count <200 /μL;when CD +4 <50 /μL,53.33% of the patients with more than three pathogen infections,thus higher than those CD +4 >350 /μL of 5.56%(χ2 =34.88,P <0.01);The high rate of opportunistic infections found on patients without the treatment of HAART(40.83%,U =9.05,P <0.01),comparing to 18.79% of those with the treatment.Conclusion The com-mon opportunistic infections in our area are HCV,various tuberculosis consumption phthisis,bacterial pneumonia and oral condida monilia infections;high rate of opportunistic infections happens when CD +4 lymphocyte count are low and lower rate on those with the treatment of HAART,offering an effective method on controlling opportunistic infections.

Objective To observe the therapeutic effects and action mechanism of moxibustion in the treatment of intestinal fibrosis in ulcerative colitis. Methods Tianshu (ST 25) and Qihai ( CV 6) were the main acupoint; other points were used according to syndrome differentiation. Sixty-five patients were randomized into two groups: Group A in which 32 cases were treated by herbpartitioned moxibustion and group B in which 33 cases were treated by bran-partitioned moxibustion. The therapeutic effects and TGF-β1, Ⅰ and Ⅲ collagen expressions were measured before and after treatment. Results In group A, 17 cases were cured, 12 cases improved and 3 failed; in group B, 1 1 cases were cured, 16 cases improved and 6 cases failed. Ⅰ , Ⅲ collagen expressions were obviously inhibited in the two groups, in group A in particular. Conclusion In the prevention and treatment of intestinal fibrosis, moxibustion may reduce the expression of TGF-β1, and hence to block or inhibit the synthesis of Ⅰ、Ⅲ collagens, and improve the structure and function.

Objective:To investigate the effects of nutritional intake in the first two weeks of life on bronchopulmonary dysplasia (BPD) in preterm infants with gestational age (GA) ≤ 32 weeks.Methods:A retrospective case-control study was conducted 154 preterm infants with birth weight ≤ 1500 g and GA ≤ 32 weeks were enrolled from neonatal intensive care unit (NICU) of Affiliated Hospital of Qingdao University between January 1, 2016 and December 31, 2017. These infants were divided into BPD group or non-BPD group. All clinical and nutritional data were collected and analyzed to investigate the effects of early-life (within 2 weeks after birth) nutritional intake on BPD.Results:Among a total of 154 eligible neonates, 68 were without BPD and 86 with BPD (55.8%). Mild, moderate and severe BPD accounted for 39.5% (34/86), 58.1%(50/86)and 2.4%(2/86)of all BPD cases respectively. GA and birth-weight of BPD group were significantly lower than that of non-BPD group [(28.35 ± 1.55)weeks vs. (30.12 ± 1.23)weeks; (1050.91 ± 190.6)g vs. (1205.88 ± 195.83)g, both P = 0.000]. The duration of mechanical ventilation in BPD group was longer than that in non-BPD group [(2.65 ± 1.08)days vs. (0.47 ± 0.12)days, P < 0.05]. The incidences of complications in BPD group, including neonatal asphyxia, sepsis and patent ductus arteriosus, were all higher than those in non-BPD group( P < 0.05). The fluids and caloric intake, enteral fluids and caloric intake were significantly lower in BPD group on Day 7 and 14 of life ( P < 0.05). The macronutrient intake in BPD group was also consistently lower, reaching statistical significance for carbohydrate intake on Day 7 and 14 of life, and for protein and lipid intake on Day 14 of life ( P < 0.05). Multivariate logistic regression analysis showed that mechanical ventilation ( OR = 2.257, 95% CI: 1.143~4.456, P = 0.019) and GA ( OR = 0.325, 95% CI: 0.215~0.49, P = 0.000) were high-risk factors for BPD. The decreased odds of developing BPD were associated with higher levels of enteral calories on Day 14 of life ( OR = 0.96, 95% CI: 0.94~0.98, P = 0.000), fluids on Day 7 of life ( OR = 0.927, 95% CI: 0.876~0.981, P = 0.009) and protein intake on Day 14 of life ( OR = 0.044, 95% CI: 0.011~0.177, P = 0.000). Conclusions:GA and mechanical ventilation were independent high-risk factors for BPD. Higher intake of protein and enteral calories were protective factors. Proactive early enteral nutrition support, adequate protein intake and decreasing the duration of mechanical ventilation may reduce the risk of BPD.

Objective To explore the cerebral circulation characteristics of patients with persistent trigeminal artery (PTA) combined with cerebrovascular diseases and their clinical relevance.Methods Eight patients with PTA,admitted our hospital from March 2010 to March 2013 and conformed by DSA,MR radiography (MRA) or CT angiography (CTA),were chosen in our study; their cerebral circulation features and clinical manifestations were retrospectively analyzed.Results In these eight patients,two were combined with cerebral infarction,one with cerebral artery stenosis,two with cerebral infarction and cerebral artery stenosis,one with transient ischemic attack,and the left two with cerebral aneurysm.Four patients complained for paroxysmal dizziness (one of them with one-side weakness),two patients complained for numbness of a limb,One patient had headache and blepharoptosis and one patient had diplopia.Saltzman type Ⅰ was noted in six patients,type H in one and special type in one.The pathogenesis of cerebral infarction was related to PTA.Conclusion The clinical features of the patients with PTA often determine by merger cerebrovascular diseases; PTA can change the normal cerebral circulation; PTA detection can be helpful in the diagnosis of the pathogenesis of multiple cerebral infarction.

Histiocytic necrotic lymphadenitis is known as Kikuchi-Fujimoto disease (KFD).KFD is a systemic disease,which is characterized by fever,necrotizing lymphadenopathy and leukopenia.However,involvement of the central and peripheral nervous system is rare.It can present as aseptic meningitis,encephalomyelitis,peripheral neuropathy,cerebellar ataxia and tremor,which makes it difficult to be differentiated with other nervous system diseases.Our review summarizes the clinical manifestations and differential diagnoses of KFD involving nervous system in order to reduce misdiagnoses and mistreatments.

OBJECTIVETo observe whether bladder controller can restore bladder function in paraplegic dogs.

METHODSFour dogs were studied after their T(10) spinal cord was transected. Electrodes implanted around S(2) bilaterally were connected to subcutaneous recievers. Microsurgical techniques were employed in dorsal rhizotomy at S(1 - 3) intradural segment. After daily stimulation, the results of bladder controller were evaluated by micturition and vesicography.

RESULTSMicturition was given under electrical stimulation with a urine volume of 80 - 140 ml per time. The mode of micturition was post-stimulus voiding. Vesicography showed that the bladder was filled and bladder neck was open in the micturition course of electric stimulation. Residual urine volume was 15 - 20 ml.

CONCLUSIONBladder controller together with a sacral deafferentation procedure can restore bladder function of paraplegic dogs.

CD70/CD27 pathway plays an important role in human immune regulation.The role of CD70/CD27 pathway in immune regulation is mainly to promote the activation and proliferation of T cells,induce the differentiation and formation of effector T cells and memory T cells,and interfere with regulatory T cells.In addition,the high level of CD70 expression in some tumor cells provides a new way for tumor immunotherapy.

OBJECTIVETo summarize surgical treatments and their corresponding curative effects on sciatic nerve injuries.

METHODSSurgical treatments on sciatic nerve injury were performed in 28 patients from January 1990 to July 2000. The treatments included neurolysis, neurolysis plus partial nerve anastomosis, nerve anastomosis and nerve transplantation. The curative effect was evaluated according to Sunderland criteria.

RESULTSOf 28 cases, 22 patients were followed up with a follow-up period of 13 months to 5 years (average 30 months). Of 22 nerves, 7 were excellent, 5 good, 7 fair and 3 poor, with an excellence rate of 54.5%.

CONCLUSIONSThe fair results of sciatic nerve injury are related to its structural character. Surgical exploration should be performed if nerve function does not recover 3 months after primary operation and if Tinel's sign and electromyogram show no signs of nerve regeneration. Electrophysiological monitoring in the operation is useful in electing surgical methods and predicting the results of nerve anastomosis.
